Food, water, energy crises, human tragedies in 2023-2025 detailed in sweeping analysis
Fuelled by climate change and relentless pressure on land and water resources, some of the most widespread and damaging drought events in recorded history have taken place since 2023, according to a UN-backed report launched today.
Prepared by the U.S. National Drought Mitigation Center (NDMC) and the UN Convention to Combat Desertification (UNCCD), with support from the International Drought Resilience Alliance (IDRA), the report, “Drought Hotspots Around the World 2023-2025,” available at https://bit.ly/4kkHApR, provides a comprehensive account of how droughts compound poverty, hunger, energy insecurity, and ecosystem collapse.
Says UNCCD Executive Secretary Ibrahim Thiaw: “Drought is a silent killer. It creeps in, drains resources, and devastates lives in slow motion. Its scars run deep.”
“Drought is no longer a distant threat,” he adds.
“It is here, escalating, and demands urgent global cooperation. When energy, food, and water all go at once, societies start to unravel. That’s the new normal we need to be ready for.”
“This is not a dry spell,” says Dr. Mark Svoboda, report co-author and NDMC Director. “This is a slow-moving global catastrophe, the worst I’ve ever seen. This report underscores the need for systematic monitoring of how drought affects lives, livelihoods, and the health of the ecosystems that we all depend on.”
“The Mediterranean countries represent canaries in the coal mine for all modern economies,” he adds. “The struggles experienced by Spain, Morocco and Türkiye to secure water, food, and energy under persistent drought offer a preview of water futures under unchecked global warming. No country, regardless of wealth or capacity, can afford to be complacent.”
A wide-ranging crisis
The new report synthesizes information from hundreds of government, scientific and media sources to highlight impacts within the most acute drought hotspots in Africa (Somalia, Ethiopia, Zimbabwe, Zambia, Malawi, Botswana, Namibia), the Mediterranean (Spain, Morocco, Türkiye), Latin America (Panama, Amazon Basin), Southeast Asia, and beyond.

“A Perfect Storm” of El Niño and climate change
The 2023–2024 El Niño event amplified already harsh climate change impacts, triggering dry conditions across major agricultural and ecological zones. Drought’s impacts hit hardest in climate hotspots, regions already suffering from warming trends, population pressures, and fragile infrastructure.
“This was a perfect storm,” says report co-author Dr. Kelly Helm Smith, NDMC Assistant Director and drought impacts researcher. “El Niño added fuel to the fire of climate change, compounding the effects for many vulnerable societies and ecosystems past their limits.”
Co-author Dr. Cody Knutson, who oversees NDMC drought planning research, underlined a recent OECD estimate that a drought episode today carries an economic cost at least twice as high as in 2000, with a 35% to 110% increase projected by 2035.
“Ripple effects can turn regional droughts into global economic shocks,” she adds. “No country is immune when critical water-dependent systems start to collapse.”
Women, children among the most affected
Most vulnerable to the effects of drought: Women, children, the elderly, pastoralists, subsistence farmers, and people with chronic illness. Health risks include cholera outbreaks, acute malnutrition, dehydration, and exposure to polluted water.
The report highlights in particular the disproportionate toll on women and children.
In Eastern Africa, forced child marriages more than doubled as families sought dowries to survive. Though outlawed in Ethiopia, child marriages more than doubled in frequency in the four regions hit hardest by the drought. Young girls who marry can bring their family income in the form of a dowry while lessening the financial burden of providing food and other necessities.
In Zimbabwe, entire school districts saw mass dropouts due to hunger, costs, and sanitation issues for girls.
In the Amazon, the drought upended life for remote Indigenous and rural communities. In some areas, the Amazon River fell to its lowest level ever recorded, leaving residents stranded – including women giving birth – and entire towns without potable water.
“The coping mechanisms we saw during this drought grew increasingly desperate,” says lead author Paula Guastello, NDMC drought impacts researcher. “Girls pulled from school and forced into marriage, hospitals going dark, and families digging holes in dry riverbeds just to find contaminated water — these are signs of severe crisis.”
“As droughts intensify, it is critical that we work together on a global scale to protect the most vulnerable people and ecosystems and re-evaluate whether our current water use practices are sustainable in today’s changing world,” Guastello says.
Says Deputy Executive Secretary of UNCCD Andrea Meza: “The report shows the deep and widespread impacts of drought in an interconnected world: from its rippling effects on price of basic commodities like rice, sugar and oil from Southeast Asia and the Mediterranean; to disruptions in access to drinking water and food in the Amazon due to low river levels, to tens of millions affected by malnutrition and displacement across Africa.”
“The evidence is clear”, adds Meza. “We must urgently invest in sustainable land and water management, land-use planning and integrated public policies to build our resilience to drought or face increasingly harsh consequences.”
Public policies and international cooperation frameworks must urgently prioritize drought resilience for the sake of societies and economies.”
Wildlife killed en masse
Lessons and recommendations
The report calls for urgent investments in drought preparedness, including:
“Drought is not just a weather event – it can be a social, economic, and environmental emergency,” says Dr. Smith. “The question is not whether this will happen again, but whether we will be better prepared next time.”
“Drought has a disproportionate effect on those with fewest resources. We can act now to reduce the effects of future droughts by working to ensure that everyone has access to food, water, education, health care and economic opportunity.”
“The nations of the world have the resources and the knowledge to prevent a lot of suffering,” Dr. Smith adds. “The question is, do we have the will?”

]]>Bonn/Ulaanbaatar – Degradation of Earth’s extensive, often immense natural pastures and other rangelands due to overuse, misuse, climate change and biodiversity loss poses a severe threat to humanity’s food supply and the wellbeing or survival of billions of people, the UN warns in a stark report today.
Authors of the Global Land Outlook Thematic Report on Rangelands and Pastoralists, launched May 21 in Ulaanbaatar, Mongolia by the UN Convention to Combat Desertification (and available post-embargo at www.unccd.int), say up to 50% of rangelands are degraded.
Symptoms of the problem include diminished soil fertility and nutrients, erosion, salinization, alkalinization, and soil compaction inhibiting plant growth, all of which contribute to drought, precipitation fluctuations, and biodiversity loss both above and below the ground.
The problem is driven largely by converting pastures to cropland and other land use changes due to population growth and urban expansion, rapidly rising food, fibre and fuel demands, excessive grazing, abandonment (end of maintenance by pastoralists), and policies that incentivise overexploitation.
What are rangelands?
The rangelands category of Earth’s land cover consists mostly of the natural grasslands used by livestock and wild animals to graze and forage.
They also include savannas, shrublands, wetlands, tundra and deserts.
Altogether, these lands constitute 54% of Earth’s land cover, account for one sixth of global food production and represent nearly one third of the planet’s carbon reservoir.
“When we cut down a forest, when we see a 100-year-old tree fall, it rightly evokes an emotional response in many of us. The conversion of ancient rangelands, on the other hand, happens in ‘silence’ and generates little public reaction,” says UNCCD Executive Secretary Ibrahim Thiaw.
“Sadly, these expansive landscapes and the pastoralists and livestock breeders who depend on them, are usually under-appreciated,” Mr. Thiaw adds. “Despite numbering an estimated half a billion individuals worldwide, pastoralist communities are frequently overlooked, lack a voice in policy-making that directly affects their livelihoods, are marginalised, and are even often seen as outsiders in their own lands.”
Mongolia Environment Minister H.E. Bat-Erdene Bat-Ulzii says: “As custodian of the largest grasslands in Eurasia, Mongolia has always been cautious in transforming rangelands. Mongolian traditions are built on the appreciation of resource limits, which defined mobility as a strategy, established shared responsibilities over the land, and set limits in consumption. We hope this report helps focus attention on rangelands and their many enormous values – cultural, environmental, and economic – which cannot be overstated. If these rangelands cannot support these massive numbers of people, what alternatives can they turn to?”
Mongolia will host the 17th UNCCD Conference of the Parties meeting in 2026, the International Year of Rangelands and Pastoralists (IYRP), declared by the United Nations General Assembly on Mongolia’s initiative.
Two billion people – small-scale herders, ranchers and farmers, often poor and marginalised – depend on healthy rangelands worldwide.
Indeed, in many West African states, livestock production employs 80% of the population. In Central Asia and Mongolia 60% of the land area is used as grazing rangelands, with livestock herding supporting nearly one third of the region’s population.
Ironically, the report underlines, efforts to increase food security and productivity by converting rangelands to crop production in mostly arid regions have resulted in degraded land and lowered agricultural yields.
The report calls out “weak and ineffective governance,” “poorly implemented policies and regulations,” and “the lack of investment in rangeland communities and sustainable production models” for undermining rangelands.
An innovative approach
The new report’s 60+ expert contributors from over 40 countries agree that past estimates of degraded rangeland worldwide – roughly 25% – “significantly underestimates the actual loss of rangeland health and productivity” and could be as much as 50%.
Rangelands are often poorly understood and a lack of reliable data undermines the sustainable management of their immense value in food provisioning and climate regulation, the report warns.
The report details an innovative conceptual approach that would enable policy-makers to stabilise, restore and manage rangelands.
The new approach is backed by experience detailed in case studies from nearly every world region, drawing important lessons from successes and missteps of rangeland management.
A core recommendation: protect pastoralism, a mobile way of life dating back millennia centred on the pasture-based production of sheep, goats, cattle, horses, camels, yaks, llamas or other domesticated herbivores, along with semi-domesticated species such as bison and reindeer.
Says Mr. Thiaw: “From the tropics to the Arctic, pastoralism is a desirable default and often the most sustainable option that should be incorporated into rangeland use planning.”
The economic engine of many countries
Rangelands are an important economic engine in many countries and define cultures. Home to one quarter of the world’s languages, they also host numerous World Heritage Sites and have shaped the value systems, customs and identities of pastoralists for thousands of years.
The report includes detailed analyses of individual countries and regions.
For example, livestock production accounts for 19% of Ethiopia’s GDP, and 4% of India’s.
Brazil – with over 250 million cattle — produces 16% of the world’s beef, valued at $7.6 billion in 2019.
In Europe, many rangelands have given way to urbanization, afforestation and renewable energy production.
In the United States, large tracts of grassland have been converted to crops, while some Canadian grasslands have been left fragile by large-scale mining and infrastructure projects. There are also positive developments noted, such as growing efforts in both countries to reintroduce bison – an animal of great cultural importance to indigenous peoples – to promote rangeland health and food security.
World areas most acutely affected by rangelands degradation, ranked in descending order:
Central Asia, China, Mongolia
The replacement of government management and oversight with privatization and agricultural industrialization left herders abandoned and dependent on insufficient natural resources causing widespread degradation.
The gradual restoration of traditional and community-based pastoralism is leading to critical advances in sustainable rangeland management.”
North Africa and Near East
The impact of climate change in one of the world’s driest regions is pushing pastoralists into poverty and degrading the rangelands on which they rely.
Updated traditional institutions, such as Agdals – reservoirs of fodder used to feed animals in periods of critical need and allowing for the regeneration of natural resources – and incipient supportive policies are improving the way rangelands are managed.
Sahel and West Africa
Conflict, power balance and border issues have interrupted livestock mobility leading to rangelands degradation.
Unified policies, recognition of pastoralists’ rights and cross-border agreements are reestablishing mobility for animal herders, crucial for landscape restoration.
South America
Climatic change, deforestation linked to industrialised agriculture and extractive activities, and land use conversion are South America’s main drivers of rangeland degradation.
Multifunctionality and diversity of pastoralist systems hold the key for restoring some of the most interesting rangelands in the world, including the Pampa, the Cerrado and Caatinga savannahs, and the Puno Andean systems.
East Africa
Migration and forced displacement caused by competing uses of land (such as hunting, tourism, etc), are evicting pastoralists from their traditional lands, causing unanticipated degradation consequences.
Women-led initiatives and improved land rights are securing pastoralists’ livelihoods, protecting biodiversity, and safeguarding the ecosystem services provided by rangelands.
North America
The degradation of ancient grasslands and dry rangelands threatens the biodiversity of iconic North American ecosystems such as the tall-grass prairies or the southern deserts.
The incorporation of indigenous people to rangeland governance is a clear step to help recover these historic landscapes.
Europe
Policies favouring industrial farming over pastoralism and misguided incentives are causing rangelands and other open ecosystems to be abandoned and degraded.
Political and economic support, including legal recognition and differentiation, can turn the tide and help address critical environmental crises such as the rising frequency and intensity of wildfires and climate change.
South Africa and Australia
Afforestation, mining, and the conversion of rangelands to other uses are causing the degradation and loss of rangelands.
The co-creation of knowledge by producers and researchers, and respect for and use of traditional wisdom held by indigenous communities, open new paths for restoring and protecting rangelands.
Paradigm shift
Halting the deterioration requires a paradigm shift in management at every level – from grassroots to global, the report concludes.
Pedro Maria Herrera Calvo, the report’s lead author, says: “The meaningful participation of all stakeholders is key to responsible rangeland governance, which fosters collective action, improves access to land and integrates traditional knowledge and practical skills”.
Achieving “land degradation neutrality” (Sustainable Development Goal 15.3) – balancing the amount and quality of healthy land to support ecosystem services and food security – also requires cross-border cooperation.
Pastoralists with generations of experience in achieving life in balance with these ecosystems should help inform this process at every step, from planning to decision-making to governance, the report says.
Solutions must be tailored to the characteristics and dynamics of rangelands, which vary widely from arid to sub-humid environments, as seen in West Africa, India or South America.
The report notes that traditional assessment methods often undervalue the real economic contribution of rangelands and pastoralism, highlighting the need for the innovative approach recommended.

Comments
“Imbalance between the supply of and demand for animal forage lands leads to overgrazing, invasive species, and the increased risk of drought and wildfires – all of which accelerate desertification and land degradation trends around the world.”
“We must translate our shared aspirations into concrete actions – stopping indiscriminate conversion of rangelands into unsuitable land uses, advocating for policies that support sustainable land management, investing in research that enhances our understanding of rangelands and pastoralism, empowering pastoralist communities to preserve their sustainable practices while also gaining tools to thrive in a changing world, and supporting all stakeholders, especially pastoralists, to implement measures that effectively thwart further degradation and preserve our land, our communities, and our cultures.”
Maryam Niamir-Fuller, Co-Chair, International Support Group for the UN’s International Year for Rangelands and Pastoralists – 2026
For the sake of future generations and economic stability, we need to improve awareness of and safeguard the immense value of rangelands. Due to their dynamic nature, predicting the consequences of rangelands degradation on economics, ecology, and societies is challenging. Managers require authoritative insights into the response of rangelands to different disturbances and management approaches, including policy tools that better capture the broad social importance of rangelands.
Carlos Manuel Rodríguez, CEO and Chairperson, Global Environment Facility
“More than half of the world’s land mass is rangeland – and yet these landscapes and the people who inhabit and manage them have been largely neglected. They are a main source of food and feed for humanity, and yet they are also the world economy’s dumping ground. It is time to shift perspective – from ‘a rangeland problem’ to ‘a sustainable rangeland solution’.
UN International Year of Rangelands & Pastoralists (IYRP) Working Group
“Pastoralists produce food in the world’s harshest environments, and pastoral production supports the livelihoods of rural populations on almost half of the world’s land. They have traditionally suffered from poor understanding, marginalization, and exclusion from dialogue. We need to bring together pastoralists and the main actors working with them to join forces and create the synergies for dialogue and pastoralist development
UN Food and Agricultural Organization (FAO)
“To have any chance of meeting global biodiversity, climate and food security goals, we simply cannot afford to lose any more of our rangelands, grasslands and savannahs. Our planet suffers from their ongoing conversion, as do the pastoralists who depend on them for their livelihoods, and all those who rely on them for food, water and other vital ecosystem services. The Global Land Outlook reinforces that too little political attention or finance is invested in protecting and restoring these critical ecosystems. National and sub-national authorities must take place-based action to safeguard and improve the health and productivity of rangelands, grasslands and savannahs – to benefit people and planet.”

]]>Two billion tons of sand and dust, equal in weight to 350 Great Pyramids of Giza, enter the atmosphere every year; UNCCD experts attribute over 25% of the problem to human activities; Wreaks havoc from Northern and Central Asia to sub-Saharan Africa; Health impacts poorly understood

Sand and dust storms are an under-appreciated problem now “dramatically” more frequent in some places worldwide, with at least 25% of the phenomenon attributed to human activities, according to the UN Convention to Combat Desertification (UNCCD).
Accompanied by policy recommendations, the warning comes as a five-day meeting takes place in Samarkand, Uzbekistan to take stock of global progress in the Convention’s implementation. The UNCCD is one of three Conventions originated at the 1992 Earth Summit in Rio de Janeiro. The other two address climate change (UNFCCC) and biodiversity (UN CBD).
The meeting, 13-17 November (www.unccd.int/cric21) , includes a high-level session on 15 November hosted by the Government of Uzbekistan on ways to address the impacts of sand and dust storms on global agriculture, industry, transportation , water and air quality, and human health.
Says Ibrahim Thiaw, UNCCD’s Executive Secretary: “The sight of rolling dark clouds of sand and dust engulfing everything in their path and turning day into night is one of nature’s most intimidating spectacles. “It is a costly phenomenon that wreaks havoc everywhere from Northern and Central Asia to sub-Saharan Africa.”
“Sand and dust storms present a formidable challenge to achieving sustainable development. However, just as sand and dust storms are exacerbated by human activities, they can also be reduced through human actions,” adds Thiaw.
While sand and dust storms (SDS) are a regionally common and seasonal natural phenomenon, the problem is exacerbated by poor land and water management, droughts, and climate change, according to UNCCD experts.
And fluctuations in their intensity, magnitude, or duration “can make SDS unpredictable and dangerous.”
With impacts far beyond the source regions, an estimated 2 billion tons of sand and dust now enters the atmosphere every year, an amount equal in weight to 350 Great Pyramids of Giza.
In some areas, desert dust doubled in the last century.
“Sand and dust storms (SDS) have become increasingly frequent and severe having substantial transboundary impacts, affecting various aspects of the environment, climate, health, agriculture, livelihoods and the socioeconomic well-being of individuals. The accumulation of impacts from sand and dust storms can be significant,” says Feras Ziadat, Technical Officer at the Food and Agriculture Organization of the UN (FAO), Chair of the UN Coalition on Combating Sand and Dust Storms.
“In source areas, they damage crops, affect livestock, and strip topsoil. In depositional areas atmospheric dust, especially in combination with local industrial pollution, can cause or worsen human health problems such as respiratory diseases. Communications, power generation, transportation, and supply chains can also be disrupted by low visibility and dust-induced mechanical failures. The United Nations Coalition on Combating Sand and Dust Storms, chaired by FAO, was created in 2019 to lead global efforts to address SDS.”
In their Sand and Dust Storms Compendium (https://bit.ly/3slJ6mE) and accompanying SDS Toolbox (https://bit.ly/3QSPWcI), the UNCCD, FAO and partners offer guidance on approaches and methodologies for collecting and assessing SDS data, monitoring and early warning, impact mitigation and preparedness, and source mapping and anthropogenic source mitigation at sub-national, national, regional and global levels.
The SDS discussion forms part of the agenda of this year’s meeting in Uzbekistan of the UNCCD’s Committee for the Review of the Implementation of the Convention (CRIC 21) and global progress in delivering the Convention’s strategic objectives. It marks the first time since its establishment that UNCCD has agreed to one of its most significant meetings in Central Asia.
The meeting comes at a critical juncture, as recent statistics published via UNCCD’s new data dashboard (https://data.unccd.int) shows the world now losing nearly 1 million square kilometers of healthy and productive land every year – some 4.2 million square kilometers between 2015-2019, or roughly the combined area of five Central Asian nations: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan.
During the meeting (at 18:00 local time / 13:00 GMT, Tuesday 14 November) UNCCD and FAO experts will launch three reports:
Sand and dust storms. A guide to mitigation, adaptation, policy and risk management measures in agriculture (https://bit.ly/40zSEad)

Preparing for sand and dust storm contingency planning with herding communities: a case study on Mongolia (https://bit.ly/3swg8Rd)
Other items on the CRIC 21 agenda include promoting sustainable land management, ensuring fair land rights for women, and tackling droughts and wildfires exacerbated by climate change and environmental degradation.
Background: Sand and dust storms
Sand and dust storms (SDS) are known by many local names: the sirocco, haboob, yellow dust, white storms, or the harmattan.
While SDS can fertilize both land and marine ecosystems, they also present a range of hazards to human health, livelihoods and the environment.
SDS events typically originate in low-latitude drylands and sub-humid areas where vegetation cover is sparse or absent.
They can also occur in other environments, including agricultural and high-latitude areas in humid regions, when specific wind and atmospheric conditions coincide. SDS events can have substantial transboundary impacts, over thousands of kilometers. Unified and coherent global and regional policy responses are needed, especially to address source mitigation, early warning systems, and monitoring.
SDS often have significant economic impacts: for example, they cost the oil sector in Kuwait an estimated US$ 190 million annually, while a single SDS event in 2009 resulted in damage estimated at US$ 229 – 243 million in Australia.
The major global sources of mineral dust are in the northern hemisphere across North Africa, the Middle East and East Asia. In the southern hemisphere, Australia, South America and Southern Africa are the main dust sources.
More than 80% of Central Asia is covered by deserts and steppes which, coupled with climate change and lasting droughts, represent a major natural source of sand and dust storms.
The dried-up Aral Sea is a major source of SDS, emitting more than 100 million tons of dust and poisonous salts every year, impacting the health not just of the people living in the vicinity, but far beyond and generating annual losses of US$ 44 million.
Recognition of SDS as a disaster risk appears to be high in North-East Asia, parts of West Asia and North America but less prominent elsewhere.
Low recognition of SDS as a disaster risk is likely due to the lack (in many cases) of significant immediate direct human fatalities or injuries from individual SDS events, and limited consolidated documentation on their long-term health, economic or other impacts.
SDS and health
SDS can be life-threatening for individuals with adverse health conditions.
Fine dust particles are carried to high tropospheric levels (up to a few kilometers high) where winds can transport them over long distances.
The health implications of SDS have been under increased research for decades, with most studies conducted in East Asia, Europe and the Middle East. There has been a lack of studies in West Africa.
A particular focus of this research has been SDS modification of air pollution.
The cause-and-effect between sand and dust in the atmosphere and health outcomes remains unclear and requires more extensive study. What can be said is that at-risk members of a population, especially those with pre-existing cardiopulmonary issues, including childhood asthma, may have a higher mortality or morbidity rate during a dust storm.
SDS can also impose major costs on the agricultural sector through crop destruction or reduced yield, animal death or lower yields of milk or meat, and damage to infrastructure.
For annual crops, losses are due to burial of seedlings or crops under sand deposits, loss of plant tissue and reduced photosynthetic activity as a result of sandblasting. This can lead to complete crop loss in a region or reduced yield.
There may also be a longer-term effect on some perennial crops due to tree or crop damage (such as lucerne/alfalfa crowns being damaged).
On a positive note, SDS dust can contain soil nutrients such as nitrogen, phosphorus and potassium, as well as organic carbon. Some places benefit from this nutrient deposition on land, and mineral and nutrient deposition on water, particularly ocean bodies. When deposited, these can provide nutrients to downwind crop or pasture areas. These limited benefits, however, are far outweighed by the harms done.
Globally, the main large dust sources are dried lakes; Local sources include glacial outwash plains, volcanic ash zones and recently plowed fields.
The multi-faceted, cross-sectoral and transnational impacts of SDS directly affect 11 of the 17 Sustainable Development Goals yet global recognition of SDS as a hazard is generally low due in part to the complexity and seasonally cumulative impact of SDS, coupled with limited data .
Insufficient information and impact assessments hinder effective decision-making and planning to effectively address SDS sources and impacts.
UNCCD helps governments create policies to promote the scaling-up of sustainable land management practices and to find and use the latest science to develop and implement effective mitigation policies.
Working with The Regional Environmental Center for Central Asia , (https://bit.ly/46aAhKq) UNCCD assists countries vulnerable to drought and sand and dust storms in Central Asia to develop and implement risk reduction strategies at national and regional level. UNCCD encourages countries to adopt a comprehensive risk reduction strategy with monitoring and early warning systems to improve preparedness and resilience to these environmental disasters.
Among the measures most needed are
A multi-sector approach bolstered by information-sharing, short- and long-term interventions, engaging multiple stakeholders, and raising awareness of SDS.
Land restoration, using soil and water management practices to protect soils and increase vegetative cover, which have been shown to significantly reduce the extent and vulnerability of source areas, and reduce the intensity of typical SDS events.
Early warning and monitoring, building on up-to-date risk knowledge, and forecasting, with all stakeholders (including at-risk populations) participating to ensure that warnings are provided in a timely and targeted manner
Impact mitigation, through preparedness to reduce vulnerability, increase resilience, and enables a timely, effective response to SDS events

The UNCCD is an international agreement on good land stewardship. It helps people, communities and countries create wealth, grow economies and secure enough food, clean water and energy by ensuring land users an enabling environment for sustainable land management. Through partnerships, the Convention’s 197 parties set up robust systems to manage drought promptly and effectively. Good land stewardship based on sound policy and science helps integrate and accelerate achievement of the Sustainable Development Goals, builds resilience to climate change and prevents biodiversity loss.
The UNCCD Secretariat led the creation of the SDS Compendium document in collaboration with the UNCCD Science-Policy Interface (SPI), the World Meteorological Organization (WMO), the World Health Organization (WHO), the UN Environment Programme (UNEP), UN Women, the Food and Agriculture Organization of the UN (FAO), the UN Development Programme (UNDP), the UN Office for Disaster Risk Reduction (UNDRR), and external experts and partners.

]]>Key role in 60% of global plant and animal extinctions; Annual costs now >$423 Billion – have quadrupled every decade since 1970; Report provides evidence, tools and options to help governments achieve ambitious new global goal on invasive alien species
The severe global threat posed by invasive alien species is underappreciated, underestimated, and often unacknowledged. According to a major new report by the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), more than 37,000 alien species have been introduced by many human activities to regions and biomes around the world. This conservative estimate is now rising at unprecedented rates. More than 3,500 of these are harmful invasive alien species – seriously threatening nature, nature’s contributions to people and good quality of life. Too often ignored until it is too late, invasive alien species are a significant challenge to people in all regions and in every country.
Approved Sept 2 in Bonn, Germany, by representatives of the 143 member States of IPBES, the Assessment Report on Invasive Alien Species and their Control finds that alongside dramatic changes to biodiversity and ecosystems, the global economic cost of invasive alien species exceeded $423 billion annually in 2019, with costs having at least quadrupled every decade since 1970.
In 2019, the IPBES Global Assessment Report found that invasive alien species are one of the five most important direct drivers of biodiversity loss – alongside changes in land- and sea-use, direct exploitation of species, climate change and pollution. On the basis of this finding, Governments tasked IPBES to provide the best available evidence and policy options to deal with the challenges of biological invasions. The resulting report was produced by 86 experts from 49 countries, working for more than four and a half years. It draws on more than 13,000 references, including very significant contributions from Indigenous Peoples and local communities, making it the most comprehensive assessment ever carried out of invasive alien species around the world.
“Invasive alien species are a major threat to biodiversity and can cause irreversible damage to nature, including local and global species extinctions, and also threaten human wellbeing,” said Professor Helen Roy (United Kingdom), co-chair of the Assessment with Prof. Anibal Pauchard (Chile) and Prof. Peter Stoett (Canada).
The authors of the report emphasize that not all alien species become invasive – invasive alien species are the subset of alien species that are known to have become established and spread, which cause negative impacts on nature and often also on people. About 6% of alien plants; 22% of alien invertebrates; 14% of alien vertebrates; and 11% of alien microbes are known to be invasive, posing major risks to nature and to people. People with the greatest direct dependence on nature, such as Indigenous Peoples and local communities, are found to be at even greater risk. More than 2,300 invasive alien species are found on lands under the stewardship of Indigenous Peoples – threatening their quality of life and even cultural identities.
While many alien species were historically introduced on purpose for their perceived benefits to people, the IPBES report finds that the negative impacts of those that do become invasive are enormous for nature and people. “Invasive alien species have been a major factor in 60% and the only driver in 16% of global animal and plant extinctions that we have recorded, and at least 218 invasive alien species have been responsible for more than 1,200 local extinctions . In fact, 85% of the impacts of biological invasions on native species are negative,” said Prof. Pauchard. Examples of such impacts include the ways that North American beavers (Castor canadensis) and Pacific Oysters (Magallana gigas) change ecosystems by transforming habitats – often with severe consequences for native species.
Nearly 80% of the documented impacts of invasive alien species on nature’s contributions to people are also negative – especially through damage to food supplies – such as the impact of the European shore crab (Carcinus maenas) on commercial shellfish beds in New England and the damage caused by the Caribbean false mussel (Mytilopsis sallei) to locally important fishery resources in India.
Similarly, 85% of documented impacts negatively affect people’s quality of life – for instance through health impacts, including diseases such as malaria, Zika and West Nile Fever, spread by invasive alien mosquito species like Aedes albopictusand Aedes aegyptii. Invasive alien species also damage livelihoods, for example in Lake Victoria where fisheries have declined due to the depletion of tilapia, as a result of the spread of water hyacinth (Pontederia crassipes), which is the world’s most widespread terrestrial invasive alien species. Lantana (Lantana camara), a flowering shrub, and the black rat (Rattus rattus) are the second and third most widespread globally, with far-reaching impacts on people and nature.
“It would be an extremely costly mistake to regard biological invasions only as someone else’s problem,” said Pauchard. “Although the specific species that inflict damages vary from place to place, these are risks and challenges with global roots but very local impacts, facing people in every country, from all backgrounds and in every community – even Antarctica is being affected.”
The report shows that 34% of the impacts of biological invasions were reported from the Americas, 31% from Europe and Central Asia, 25% from Asia and the Pacific and about 7% from Africa. Most negative impacts are reported on land (about 75%) – especially in forests, woodlands and cultivated areas – with considerably fewer reported in freshwater (14%) and marine (10%) habitats . Invasive alien species are most damaging on islands, with numbers of alien plants now exceeding the number of native plants on more than 25% of all islands.
“The future threat from invasive alien species is a major concern,” said Prof. Roy. “37% of the 37,000 alien species known today have been reported since 1970 – largely caused by rising levels of global trade and human travel. Under ‘business-as-usual’ conditions, we project that total numbers of alien species will continue to increase in this way.”
“But business-as-usual is actually unlikely,” continues Roy. “With so many major drivers of change predicted to worsen, it is expected that the increase of invasive alien species and their negative impacts, are likely to be significantly greater. The accelerating global economy, intensified and expanded land- and sea-use change, as well as demographic changes are likely to lead to increases in invasive alien species worldwide. Even without the introduction of new alien species, already established alien species will continue to expand their ranges and spread to new countries and regions. Climate change will make the situation even worse.” The report underscores that interactions between invasive alien species and other drivers of change will be likely to amplify their impacts – for example invasive alien plants can interact with climate change, often resulting in more intense and frequent fires, such as some of the devastating wildfires experienced recently around the world, releasing even more carbon dioxide into the atmosphere.
The IPBES experts point to the generally insufficient measures in place to tackle these challenges. While 80% of countries have targets related to managing invasive alien species in their national biodiversity plans, only 17% have national laws or regulations specifically addressing these issues. This also increases the risk of invasive alien species for neighbouring States. The report finds that 45% of all countries do not invest in the management of biological invasions.
On a more positive note, the report highlights that future biological invasions, invasive alien species, and their impacts, can be prevented through effective management and more integrated approaches. “The good news is that, for almost every context and situation, there are management tools, governance options and targeted actions that really work,” said Prof. Pauchard. “Prevention is absolutely the best, most cost-effective option – but eradication, containment and control are also effective in specific contexts. Ecosystem restoration can also improve the results of management actions and increase the resistance of ecosystems to future invasive alien species . Indeed, managing invasive alien species can help to mitigate the negative effects of other drivers of change.”
Prevention measures – such as border biosecurity and strictly enforced import controls – are identified by the report as having worked in many instances, such as the successes achieved in Australasia in reducing the spread of the brown marmorated stink bug (Halyomorpha halys). Preparedness, early detection and rapid response are shown to be effective at reducing rates of alien species establishment, and to be especially critical for marine and connected water systems . The PlantwisePlus programme, assisting smallholder farmers in Africa, Asia and Latin America is spotlighted by the report as a good example of the importance of general surveillance strategies to detect new alien species.
Eradication has been successful and cost-effective for some invasive alien species, especially when their populations are small and slow-spreading, in isolated ecosystems such as islands. Some examples of this are in French Polynesia where the black rat (Rattus rattus) and rabbit (Oryctolagus cuniculus) have been successfully eradicated. The report indicates that eradication of alien plants is more challenging due to the length of time that seeds may lie dormant in soil. The authors add that successful eradication programmes depend on, amongst other elements, the support and engagement of stakeholders and Indigenous Peoples and local communities.
When eradication is not possible for different reasons, invasive alien species can often be contained and controlled – especially in land-based and closed water systems, as well as in aquaculture – an example being the containment of the invasive alien Asian tunicate (Styela clava) in aqua-cultured blue mussels in Canada. Successful containment can be physical, chemical or biological – although the appropriateness and effectiveness of each option is dependent on local context. The use of biological control for invasive alien plants and invertebrates, such as introducing a rust fungus (Puccinia spegazzinii) to control bitter vine (Mikania micrantha) in the Asia-Pacific region, has been effective – with success in more than 60% of known cases.
“One of the most important messages from the report is that ambitious progress in tackling invasive alien species is achievable,” said Prof. Stoett. “What is needed is a context-specific integrated approach, across and within countries and the various sectors involved in providing biosecurity, including trade and transportation; human and plant health; economic development and more. This will have far-reaching benefits for nature and people.” Options explored in the report include considering coherent policies and codes of conduct across sectors and scales; commitment and resourcing; public awareness and engagement, such as citizen science campaigns like those promoting ‘check, clean and dry’; open and interoperable information systems; filling knowledge gaps (the authors identify more than 40 areas where research is needed); as well as inclusive and fair governance.
“The immediate urgency of invasive alien species, with extensive and growing harm to nature and people, makes this report so valuable and timely,” said Dr. Anne Larigauderie, the Executive Secretary of IPBES. “The Governments of the world agreed, in December last year, as part of the new Kunming-Montreal Global Biodiversity Framework, to reduce the introduction and establishment of priority invasive alien species by at least 50% by 2030. This is a vital, but also very ambitious commitment. The IPBES Invasive Alien Species Report provides the evidence, tools and options to help make this commitment more achievable.”

IPBES Partner Comments
Humanity has been moving species around the world for centuries. This practice has brought some positives. However, when imported species run rampant and unbalance local ecosystems, indigenous biodiversity suffers. As a result, invasive species have become one of the five horsemen of the biodiversity apocalypse that is riding down harder and faster upon the world.
While the other four horsemen – changing land- and sea-use, over exploitation, climate change and pollution – are relatively well understood, knowledge gaps remain around invasive species. The IPBES Invasive Alien Species Report is a welcome effort to close these gaps. By providing critical information on trends in invasive species and policy tools to address them, this report can provide a springboard to concrete action on invasive species.
I ask all decision-makers to use this report’s recommendations as a basis to act on this growing threat to biodiversity and human well-being – and make a real contribution to achieving the Kunming-Montreal Global Biodiversity Framework by 2030.
Inger Andersen, Executive Director, United Nations Environment Programme (UNEP)
Invasive alien species pose a substantial threat to livelihoods and food security around the world. They can, for example, manifest as destructive crop or forest pests or displace species targeted by fisheries. They are an important driver of biodiversity loss and hence a threat to the various ecosystem services that support agricultural production and sustainable livelihoods.
The information contained in this report will contribute greatly to efforts to combat the spread of invasive alien species and to meeting Target 6 of the Kunming-Montreal Global Biodiversity Framework. It will be especially valuable for all of us who work to integrate the conservation and sustainable use of biodiversity into the world’s agrifood systems to enhance their productivity and resilience.
QU Dongyu, Director-General, Food and Agriculture Organization of the United Nations (FAO)
Invasive alien species — plants, animals or microorganisms that are introduced intentionally or unintentionally into areas where they are not native — remain one of the most striking symptoms of the adverse effect of human activities on our natural world. They not only contribute to wildlife species extinctions, but also pose a rapidly growing risk to progress on the Global Goals — affecting entire ecosystems, economies and food security to human health, wellbeing, and livelihoods.
As anthropogenic factors such as climate change provide the perfect petri dish for alien species to multiply and spread, our decisions and actions must be rooted in a comprehensive understanding of this threat and its future implications.
Addressing this need, this timely analysis by IPBES combines the latest science, data, and new thinking to guide countries, communities, and the United Nations family to prevent, mitigate, and manage invasive alien species, a pivotal step towards advancing the Kunming-Montreal Global Biodiversity Framework targets. That includes leveraging invaluable local knowledge and outlining a range of practical solutions.
This new understanding will allow our global community to take new measures to protect both people and planet from the unwanted and severe consequences of invasive alien species.
Achim Steiner, Administrator, United Nations Development Programme (UNDP)
Invasive alien species are one of the five main direct drivers of biodiversity loss globally and the threats they pose to species, to ecosystems and to human well-being are rapidly increasing.
The Kunming-Montreal Global Biodiversity Framework, in its Target 6, aims to tackle the impacts of invasive alien species on biodiversity and ecosystem services, and to reduce the rate of introduction and establishment of invasive alien species by at least 50% by 2030. This is an ambitious target, especially when we consider the increasing levels of global trade and travel.
The IPBES Assessment will provide the best available scientific knowledge to help countries and stakeholders understand and address this growing threat. It will identify tools and policy measures for identifying and regulating pathways of introduction and for eliminating or controlling invasive species that have already been established. Critically, the assessment will take into account different value systems and help to focus actions on priority species, pathways and sites.
Congratulations to IPBES for this critical work. I look forward to seeing its active use by Parties and stakeholders. I believe it will be a critical resource to facilitate the urgent actions necessary to achieve Target 6 and work towards living in harmony with nature.

Humanity is “at a crossroads” when it comes to managing drought and accelerating mitigation must be done “urgently, using every tool we can,” says a new report from the United Nations Convention to Combat Desertification (UNCCD).

“Drought In Numbers, 2022,” released today to mark Drought Day at UNCCD’s 15th Conference of Parties (COP15, 9-20 May in Abidjan, Côte d’Ivoire) – calls for making a full global commitment to drought preparedness and resilience in all global regions a top priority.
The report, an authoritative compendium of drought-related information and data, helps inform negotiations of one of several decisions by UNCCD’s 196 member states, to be issued 20 May at the conclusion of COP15.
“The facts and figures of this publication all point in the same direction: an upward trajectory in the duration of droughts and the severity of impacts, not only affecting human societies but also the ecological systems upon which the survival of all life depends, including that of our own species.” says Ibrahim Thiaw, Executive Secretary of the UNCCD.
The report creates a compelling call to action. For example:
Unless action is stepped up:
“We are at a crossroads,” says Mr. Thiaw. “We need to steer toward the solutions rather than continuing with destructive actions, believing that marginal change can heal systemic failure.”
“One of the best, most comprehensive solutions is land restoration, which addresses many of the underlying factors of degraded water cycles and the loss of soil fertility. We must build and rebuild our landscapes better, mimicking nature wherever possible and creating functional ecological systems.”
Beyond restoration, he adds, is the need for a paradigm shift from ‘reactive’ and ‘crisis-based’ approaches to ‘proactive’ and ‘risk-based’ drought management approaches involving coordination, communication and cooperation, driven by sufficient finance and political will.
Needed as well:
The new UNCCD report notes that 128 countries have expressed willingness to achieve or exceed Land Degradation Neutrality. And nearly 70 countries participated in the UNCCD’s global drought initiative, which aims to shift from reactive approaches to drought to a proactive and risk-reducing approach.
Mr. Thiaw underlined the importance of promoting public awareness about desertification and drought, and letting people know the problems can be effectively tackled “through ingenuity, commitment and solidarity.”
“We all must live up to our responsibility to ensure the health of present and future generations, wholeheartedly and without delay.”
The COP15 decision on drought is expected to touch on five interrelated areas:

]]>The way land resources – soil, water and biodiversity – are currently mismanaged and misused threatens the health and continued survival of many species on Earth, including our own, warns a stark new report from the United Nations Convention to Combat Desertification (UNCCD).

It also points decision makers to hundreds of practical ways to effect local, national and regional land and ecosystem restoration.
UNCCD’s evidence-based flagship Global Land Outlook 2 (GLO2) report, five years in development with 21 partner organizations, and with over 1,000 references, is the most comprehensive consolidation of information on the topic ever assembled.
It offers an overview of unprecedented breadth and projects the planetary consequences of three scenarios through 2050: business as usual, restoration of 50 million square km of land, and restoration measures augmented by the conservation of natural areas important for specific ecosystem functions.
It also assesses the potential contributions of land restoration investments to climate change mitigation, biodiversity conservation, poverty reduction, human health and other key sustainable development goals.
Warns the report: “At no other point in modern history has humanity faced such an array of familiar and unfamiliar risks and hazards, interacting in a hyper-connected and rapidly changing world. We cannot afford to underestimate the scale and impact of these existential threats.”
“Conserving, restoring, and using our land resources sustainably is a global imperative, one that requires action on a crisis footing…Business as usual is not a viable pathway for our continued survival and prosperity.”
GLO2 offers hundreds of examples from around the world that demonstrate the potential of land restoration. It is being released before the UNCCD’s 15th session of the Conference of Parties to be held in Abidjan, Côte d’Ivoire (COP15, 9-20 May).
Says Ibrahim Thiaw, Executive Secretary of the UNCCD: “Modern agriculture has altered the face of the planet more than any other human activity. We need to urgently rethink our global food systems, which are responsible for 80% of deforestation, 70% of freshwater use, and the single greatest cause of terrestrial biodiversity loss.”
“Investing in large-scale land restoration is a powerful, cost-effective tool to combat desertification, soil erosion, and loss of agricultural production. As a finite resource and our most valuable natural asset, we cannot afford to continue taking land for granted.”
Future scenarios
The report predicts the outcomes by 2050 and risks involved under three scenarios:
• Baseline: Business as usual, continuing current trends in land and natural resource degradation, while demands for food, feed, fiber, and bioenergy continue to rise. Land management practices and climate change continue to cause widespread soil erosion, declining fertility and growth in yields, and the further loss of natural areas due to expanding agriculture.
By 2050:
• Restoration: Assumes the restoration of around 5 billion hectares (50 million square kilometers or 35% of the global land area) using measures such as agroforestry, grazing management, and assisted natural regeneration. (Current international pledges: 10 million square kilometers).
By 2050:
• Restoration and Protection: This scenario includes the restoration measures, augmented with protection measures of areas important for biodiversity, water regulation, conservation of soil and carbon stocks, and provision of critical ecosystem functions.
By 2050:
See below for additional scenario projections and information
Other key points in the report include:
GLO2 offers hundreds of good practice snapshots from around the world that illustrate context-specific measures to combat environmental degradation, restore land health, and improve living conditions.
Many regenerative agriculture practices have the potential to increase crop yields and improve their nutritional quality while reducing greenhouse gas emissions and drawing down carbon from the atmosphere, it says.
Examples include rewilding – reducing the human footprint to allow natural ecological processes to re-establish themselves – in the Greater Côa Valley in northern Portugal and the Iberá wetlands in Argentina; drought preparedness and risk reduction through national programmes in Mexico, the USA, and Brazil; sand and dust storm source mitigation in Iraq, China, and Kuwait; and gender-responsive land restoration in Mali, Nicauragua, and Jordan. There are also cases of integrated flood and drought strategies as well as forest landscape restoration using high-value crops.
Good practices can involve terrace and contour farming, conserving and restoring watersheds, and rainwater harvesting and storage. In addition to their economic benefits, these measures improve water retention and availability, prevent soil erosion and landslides, reduce flood risk, sequester carbon, and protect biodiversity habitat.
Africa’s Great Green Wall, meanwhile, which aims to restore the continent’s degraded landscapes, exemplifies “a regional restoration initiative that embraces an integrated approach with the promise of transforming the lives of millions of people,” says the report.
“The case studies from around the world showcased in GLO2 make clear that land restoration can be implemented in almost all settings and at many spatial scales, suggesting that every country can design and implement a tailored land restoration agenda to meet their development needs,” says Mr. Thiaw.
Many of the cases, he adds, underscore the value of education, training, and capacity building, not just for local communities, but also for government officials, land managers, and development planners. Linking local engagement to national policies and budgets will help ensure a responsive and well-aligned restoration agenda that delivers tangible outcomes for people, nature, and the climate.
Preventing, halting, and reversing the degradation of ecosystems worldwide is the focus of the UN Decade on Ecosystem Restoration (2021-2030), which calls for a broad and balanced response, addressing all ecosystems and their connectivity to reestablish a healthy landscape mosaic. These efforts are closely aligned with SDG target 15.3, which calls on countries to strive to achieve Land Degradation Neutrality (LDN) by 2030.
“Hope remains as the decade of restoration has begun,” says Mr. Thiaw. “Now is the time to harness political will, innovation, and collective action to restore our land and soil for short-term recovery and long-term regeneration to ensure a more stable and resilient future.”

Comments
“The second edition of the Global Land Outlook is a must-read for the biodiversity community. The future of biodiversity is precarious. We have already degraded nearly 40 % and altered 70 % of the land. We cannot afford to have another “lost decade” for nature and need to act now for a future of life in harmony with nature. The GLO2 shows pathways, enablers and knowledge that we should apply to effectively implement the post-2020 Global Biodiversity Framework.”
“Land is the operative link between biodiversity loss and climate change, and therefore must be the primary focus of any meaningful intervention to tackle these intertwined crises. Restoring degraded land and soil provides fertile ground on which to take immediate and concerted action.”
“As a global community we can no longer rely on incremental reforms within traditional planning and development frameworks to address the profound development and sustainability challenges we are facing in coming decades. A rapid transformation in land use and management practices that place people and nature at the center of our planning is needed, prioritizing job creation and building vital skill sets while giving voice to women and youth who have been traditionally marginalized from decision making.”
“Just as COVID-19 vaccines were developed, tested, and rolled out at unprecedented speed and scale, so too must land restoration and other nature-based solutions be undertaken to prevent further environmental decline and ensure a healthy and prosperous future. We can reduce the risk of zoonotic disease transmission, increase food and water security, and improve human health and livelihoods by managing, expanding, and connecting protected and natural areas, improving soil, crop, and livestock health in food systems, and creating green and blue spaces in and around cities.”
“Restoring long term health and productivity in food landscapes is a top priority to ensure future sustainability. Much as an investor uses financial capital to generate profits, regenerating a forest or improving soil health provides returns in the form of a future supply of timber or food.”
“Indigenous Peoples and local communities are proven land stewards. The recognition of their rights and their involvement in the long-term management of their lands and of protected areas will be vital to success.”
“By designing an innovative, customized land restoration agenda that suits their needs, capacities, and circumstances, countries and communities can recover lost natural resources and better prepare for climate change and other looming threats.”

GLO2: Additional scenario projections
Baseline: Business as usual
By 2050:
Restoration Scenario
Assumes that land restoration done on a massive scale – across a potential 50 million square kilometers (5 billion hectares) with measures such as:
This scenario envisions these measures applied to roughly 16 million square kilometers of cropland, 22 million of grazing land, and 14 million of natural areas. Sub-Saharan Africa and Latin America are estimated to have the largest areas with the potential for land restoration.
Compared to the baseline scenario, by 2050:
Restoration and protection scenario, projections
This scenario includes the restoration measures, augmented with protection measures expanded to cover close to half of the Earth’s land surface by 2050 – a threefold increase on the current coverage. These protected areas are important for biodiversity, water regulation, conservation of soil and carbon stocks, and provision of critical ecosystem functions.
However, significantly increasing the extent of protected land would limit the expansion of agriculture. Under this constraint, current yields would have to be 9% higher by 2050 than in the baseline scenario to meet expected demand. Nonetheless, food prices are projected to increase, particularly in South and Southeast Asia, where a scarcity of agricultural land is already impacting food security.
Under this scenario, most of the new protected areas would have to be in sub-Saharan Africa and Latin America.
When compared to the baseline, the restoration and protection scenario would mean, by 2050:

Notes to editors
Land degradation: The persistent or long-term loss of land-based natural capital. It gives rise to poverty, hunger, and environmental pollution, while making communities more vulnerable to disease and disasters like drought, floods, or wildfires. This is especially true in the drylands that cover more than 45% of the Earth’s land surface, home to one in three people.
Land restoration: A continuum of sustainable land and water management practices that can be applied to conserve or ‘rewild’ natural areas, ‘up-scale’ nature-positive food production in rural landscapes, and ‘green’ urban areas, infrastructure, and supply chains. Regenerative land use practices employed to boost soil health or recharge groundwater also enhance our ability to cope with drought, floods, wildfires, and sand and dust storms.

]]>1st assessment of water security in Africa is based on 10 indicators
Despite global Sustainable Development Goals and commitments made in 2015, just 29 African nations have made some progress over the past three to five years, 25 have made none, according to the UN’s first-ever assessment of water security in Africa.

Published on the eve of World Water Day (March 22) by UN University’s Canadian-based Institute for Water Environment and Health, the assessment employed 10 indicators to quantify water security in Africa’s 54 countries. Water security is elaborated below.
UNU-INWEH authors Grace Oluwasanya, Duminda Perera, Manzoor Qadir and Vladimir Smakhtin, the Institute’s Director, say the assessment is limited by “very poor” data on water security-related issues such as access to drinking water or sanitation, but it nevertheless offers some “preliminary but obvious conclusions.”
“Data limitations do not change the main outcome of this assessment, which is strong and clear,” says lead author Grace Oluwasanya. “Overall levels of water security in Africa are low. Not a single country let alone a subregion have at present achieved a state that can be seen as ‘model’ or even ‘effective’ stage of water security.”
Says co-author Duminda Perera: “This assessment for African countries aimed to create a quantitative starting point and a platform for subsequent discussions with national, regional and international agents; it is neither a prescription nor a guide.”
“As this quantitative tool develops, it will help generate targeted policy recommendations and inform decision-making and public-private investments toward achieving water security in Africa.”
Results in brief
Overall
Except for Egypt, all country scores are below 70 (on a scale of 100). Only 13 of 54 countries reached a modest level of water security in recent years, and over a third are deemed to have levels of water security below the threshold of 45.
Together, the 19 countries below the threshold are home to half a billion people.
Egypt, Botswana, Gabon, Mauritius and Tunisia are Africa’s top five most water-secure countries in Africa, yet with only modest absolute levels of water security achieved.
Somalia, Chad and Niger appear to be the least water-secure countries in Africa.
There has been little progress in national water security of most African states over the past three to five years, the report finds. The number of countries that made some progress (29) is close to the number of those that made none (25).
Indicator 1
Access to drinking water ranged from 99% in Egypt to 37% in the Central African Republic, and between subregions from 92% in North Africa to 62% in Central Africa. Africa’s average basic drinking water service is 71%, “leaving behind some 29% of the total population” or more than 353 million people.
Indicator 2
Access to sanitation is broadly similar at the subregional level, but a few countries — Seychelles and most countries in North Africa countries — have reached or nearly reached 100%. The most challenged countries are Chad and Ethiopia (under 20% access), with 60% average access to even limited sanitation; thus at least 40% of the total population (483 million people) are left behind.
Indicator 3
Access to hygiene facilities and practices (e.g. hand washing) are greatest in North Africa (67%), worst in West Africa (with Rwanda, Liberia lowest among eight countries with less than 10% access; Chad and the Central African Republic suffer the highest number of deaths from diarrhea).
Indicator 4
Per capita water availability is highest in Central Africa (with the Republic of Congo considered Africa’s most water-rich country — over 31,000 cubic meters per capita), while half of North African countries appear to be absolutely water scarce — less than 500 cubic meters of water per capita per annum. Due to their population growth, water availability has recently declined in West, Central and Southern Africa sub-region, and, on a country scale, in Ivory Coast, Cameroon, Somalia, Mozambique, and Malawi.
Indicator 5
Water use efficiency appears to be lowest in North Africa (with Somalia lowest at the national level) highest in Central Africa (with Angola highest at a national level). In general, agriculture-dominant countries score lower. An improvement seen in water use efficiency in Africa as a whole is primarily due to efforts in Tunisia, Gambia, Burkina Faso, Rwanda, and Uganda, but poor data quality makes assessment difficult.
Indicator 6
Water infrastructure is deemed best in the Southern Africa sub-region, worst in East Africa. South Africa, with over 25% of all large dams in Africa, is outscored by Ghana, Zimbabwe, and Zambia, likely due to just one mega reservoir in those countries. Half of all countries score very low, reflecting the continent’s low level of water storage development. Only Ethiopia and Namibia have increased their storage over recent years, while Ivory Coast and Gabon have shown a decline, partly explained by rising populations with no or minimal increase in storage. Africa-average per capita storage capacity increased by only 3% over five recent years.
Indicator 7
Wastewater treatment scores are highest in North African countries, lowest in East and West Africa, where 12 countries in each region treat less than 5% of wastewater. No country treats more than 75%, only Tunisia, Egypt and Lesotho treat over 50% and 67% of African countries treat less than 5%. The issue is poorly tracked in Africa overall.
Indicator 8
Water governance appears to be most advanced in North and Southern Africa sub-regions, while Central Africa the least advanced. Nationally, Ghana reported reaching 86% of Integrated Water Resource Management (IWRM) implementation, a significant improvement in just two years. Liberia, Guinea-Bissau, and Comoros are the lowest-performing countries, but again the assessment may be affected by the quality of national reporting.
Indicator 9
Disaster risk has either remained unchanged (North and Southern Africa sub-regions) or increased. North Africa appears to be the least risky subregion, West Africa the riskiest. Egypt appears to be the least risky country, while Cape Verde is the most, followed by Djibouti and Comoros. Some 49 of 54 African countries have seen increased disaster risk scores over five recent years, explained by the impacts of changing climate worsening countries’ exposure to natural disasters and outpacing their ability to adapt.
Indicator 10
Water dependency on neighboring nations and water resources variability: Egypt stands out as Africa’s most water-dependent country; the Southern Africa sub-region has the most variable water resources. Naturally existing physiographic conditions may, to an extent, determine how much effort is needed for a country to achieve higher levels of water security.
Call for global standards
To compare Africa’s situation globally, the authors call for global standards for water security measurement data and assessment.
“Some critical components of water security simply cannot be assessed without introducing surrogates or proxies,” as used in the report in the case of drinking water and sanitation, for example.
“With such poor data availability, progress toward water security is difficult to assess accurately.”
For example, it is not possible to estimate the percentage of the African population that will have access to safely managed drinking water services or safely managed sanitation by 2030, a key UN Sustainable Development Goal globally agreed in 2015.
“Data availability – or the lack of it – in itself may be an excellent indicator of water security,” says Dr. Oluwasanya. “Action needs to be taken immediately by national governments with support from international agents to radically improve data collection efforts for Africa.”
What is water security?
The UN’s concept of water security encompasses various needs and conditions — water for drinking, economic activity, ecosystems, hazard resilience, governance, transboundary cooperation, financing, and political stability.
Hence water security is not just about how much natural water a country has but also how well the resource is managed. It is defined as “The capacity of a population to safeguard sustainable access to adequate quantities of acceptable quality water for sustaining livelihoods, human well-being, and socio-economic development, for ensuring protection against water-borne pollution and water-related disasters, and for preserving ecosystems in a climate of peace and political stability.”
UNU-INWEH led the UN’s development and definition of water security and its related tools are now the most widely-accepted in the world. This was a fundamental milestone, contributing to conceptualization of the SDGs and to on-going efforts to assess national water security in a quantifiable way.
The assessment tool is still a work in progress, Dr. Smakhtin notes, adding that UNU-INWEH’s goal is to have by 2025 — five years before the deadline for meeting the UN’s Agenda 2030 — “an improved, influential and nationally-owned tool” for assessing water security in all African countries.

]]>Even the Arctic, previously all but immune, faces rising wildfire risk; Wildfires and climate change are “mutually exacerbating”; Governments are called to radically shift their investments to focus on prevention and preparedness
Climate change and land-use change are projected to make wildfires more frequent and intense, with a global increase of extreme fires of up to 14 per cent by 2030, 30 per cent by the end of 2050 and 50 per cent by the end of the century, according to a new report by the UN Environment Programme (UNEP) and GRID-Arendal.

The paper calls for a radical change in government spending on wildfires, shifting their investments from reaction and response to prevention and preparedness.
The report, Spreading like Wildfire: The Rising Threat of Extraordinary Landscape Fires, finds an elevated risk even for the Arctic and other regions previously unaffected by wildfires. The report is released before representatives of 193 nations convene in Nairobi for the resumed 5th session of the UN Environment Assembly (UNEA-5.2), between 28 February and 2 March, 2022.
The publication calls on governments to adopt a new ‘Fire Ready Formula,’ with two-thirds of spending devoted to planning, prevention, preparedness, and recovery, with one third left for response. Currently, direct responses to wildfires typically receive over half of related expenditures, while planning and prevention receive less than one per cent.
To prevent fires, authors call for a combination of data and science-based monitoring systems with indigenous knowledge and for a stronger regional and international cooperation.
Current government responses to wildfires are often putting money in the wrong place. Those emergency service workers and firefighters on the frontlines who are risking their lives to fight forest wildfires need to be supported. We have to minimize the risk of extreme wildfires by being better prepared: invest more in fire risk reduction, work with local communities, and strengthen global commitment to fight climate change” said Inger Andersen, UNEP Executive Director.
Wildfires disproportionately affect the world’s poorest nations. With an impact that extends for days, weeks and even years after the flames subside, they impede progress towards the UN Sustainable Development Goals and deepen social inequalities:
Wildfires and climate change are mutually exacerbating. Wildfires are made worse by climate change through increased drought, high air temperatures, low relative humidity, lightning, and strong winds resulting in hotter, drier, and longer fire seasons. At the same time, climate change is made worse by wildfires, mostly by ravaging sensitive and carbon-rich ecosystems like peatlands and rainforests. This turns landscapes into tinderboxes, making it harder to halt rising temperatures.
Wildlife and its natural habitats are rarely spared from wildfires, pushing some animal and plant species closer to extinction. A recent example is the Australian 2020 bushfires, which are estimated to have wiped out billions of domesticated and wild animals.
There is a critical need to better understand the behaviour of wildfires. Achieving and sustaining adaptive land and fire management requires a combination of policies, a legal framework and incentives that encourage appropriate land and fire use.
The restoration of ecosystems is an important avenue to mitigate the risk of wildfires before they occur and to build back better in their aftermath. Wetlands restoration and the reintroduction of species such as beavers, peatlands restoration, building at a distance from vegetation and preserving open space buffers are some examples of the essential investments into prevention, preparedness and recovery.
The report concludes with a call for stronger international standards for the safety and health of firefighters and for minimising the risks that they face before, during and after operations. This includes raising awareness of the risks of smoke inhalation, minimising the potential for life-threatening entrapments, and providing firefighters with access to adequate hydration, nutrition, rest, and recovery between shifts.
The report was commissioned in support of UNREDD and the UN Decade on Ecosystem Restoration. UNEP will be exploring how further investments can be made to reduce fire risks in critical ecosystems around the world.

]]>Of the 18 science news releases produced in 2021, 16 were environment-themed: food waste, e-waste, oceans, biodiversity, dams, and floods. And one announced 14 living male relatives of Leonardo da Vinci, advancing a project investigating his DNA.

These releases generated over 9,200 news articles, published at thousands of online news sites in scores of countries and dozens of languages, ~33 billion potential public impressions in all, according to the Meltwater news search engine, which estimates actual impressions via online news sites at 825 million. Millions of additional impressions were also generated via print newspapers, magazines, radio, TV and social media.
With thanks to the researchers and collaborators behind these stories, and to the many journalists who covered them, the following releases were the most noted last year.
]]>Unprecedented changes in climate and biodiversity, driven by human activities, have combined and increasingly threaten nature, human lives, livelihoods and well-being around the world. Biodiversity loss and climate change are both driven by human economic activities and mutually reinforce each other. Neither will be successfully resolved unless both are tackled together.

This is the message of a workshop report, published today by 50 of the world’s leading biodiversity and climate experts.
The peer-reviewed workshop report is the product of a four-day virtual workshop between experts selected by a 12-person Scientific Steering Committee assembled by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and the Intergovernmental Panel on Climate Change (IPCC) – the first-ever collaboration between these two intergovernmental bodies.
The report finds that previous policies have largely tackled biodiversity loss and climate change independently of each other, and that addressing the synergies between mitigating biodiversity loss and climate change, while considering their social impacts, offers the opportunity to maximize benefits and meet global development goals.
“Human-caused climate change is increasingly threatening nature and its contributions to people, including its ability to help mitigate climate change. The warmer the world gets, the less food, drinking water and other key contributions nature can make to our lives, in many regions” said Prof. Hans-Otto Pörtner, co-chair of the Scientific Steering Committee.
“Changes in biodiversity, in turn, affect climate, especially through impacts on nitrogen, carbon and water cycles,” he said. “The evidence is clear: a sustainable global future for people and nature is still achievable, but it requires transformative change with rapid and far-reaching actions of a type never before attempted, building on ambitious emissions reductions. Solving some of the strong and apparently unavoidable trade-offs between climate and biodiversity will entail a profound collective shift of individual and shared values concerning nature – such as moving away from the conception of economic progress based solely on GDP growth, to one that balances human development with multiple values of nature for a good quality of life, while not overshooting biophysical and social limits.”
The authors also warn that narrowly-focused actions to combat climate change can directly and indirectly harm nature and vice-versa, but many measures exist that can make significant positive contributions in both areas.
Among the most important available actions identified in the report are:

The report authors stress that while nature offers effective ways to help mitigate climate change, these solutions can only be effective if building on ambitious reductions in all human-caused greenhouse gas emissions. “Land and ocean are already doing a lot – absorbing almost 50% of CO2 from human emissions – but nature cannot do everything,” said Ana María Hernández Salgar, Chair of IPBES. “Transformative change in all parts of society and our economy is needed to stabilize our climate, stop biodiversity loss and chart a path to the sustainable future we want. This will also require us to address both crises together, in complementary ways.”
Highlighting the significance of the co-sponsored workshop, Dr. Hoesung Lee, Chair of the IPCC, said: “Climate change and biodiversity loss combine to threaten society – often magnifying and accelerating each other. By focusing on synergies and trade-offs between biodiversity protection and climate change mitigation and adaptation, this workshop advanced the debate on how to maximize benefits to people and the planet. It also represented an important step in collaboration between our two communities.”
“It may be impossible to achieve win-win synergies, or even manage the tradeoffs between climate and biodiversity actions in every single patch of a landscape or seascape,” said Prof. Pörtner, “But achieving sustainable outcomes becomes progressively easier when integrating a mix of actions at larger spatial scales, through cross-border collaboration and joint consultative spatial planning, which is why it is important to also address the lack of effective governance systems and mechanisms to improve integration between solutions for climate change and biodiversity.”

The Governments of the United Kingdom and of Norway co-hosted the virtual workshop. “This is an absolutely critical year for nature and climate,” said Lord Zac Goldsmith, UK Minister of State for Pacific and the Environment. “With the UN Biodiversity Conference in Kunming, and the Glasgow Climate Change Conference in the UK, we have an opportunity and responsibility to put the world on a path to recovery. This hugely valuable report by the experts of IPBES and IPCC makes it clear that addressing biodiversity loss and climate change together offers our best chance of doing so.”
Sveinung Rotevatn, Norwegian Minister for Climate and Environment added: “Policies, efforts and actions to solve the global biodiversity and climate crises will only succeed if they are based on the best knowledge and evidence, which is why Norway welcomes this expert workshop report. It is clear that we cannot solve these threats in isolation – we either solve both or we solve neither.”
Paying tribute to the work of all the authors and expert reviewers, the Executive Secretary of IPBES, Dr. Anne Larigauderie, also recalled the recent and tragic passing of Prof. Robert Scholes, the other Co-Chair of the workshop’s Scientific Steering Committee, and his many contributions to both the IPCC and IPBES.
It is important to note that the workshop report has not been subjected to IPBES or IPCC review, and that IPBES and IPCC co-sponsorship of the workshop does not imply IPBES or IPCC endorsement or approval of the workshop or its conclusions.
