Aridity: The ‘existential crisis’ redefining life on EarthFive billion people could be affected by 2100Riyadh, Saudi Arabia – Even as dramatic water-related disasters such as floods and storms intensified in some parts of the world, more than three-quarters of Earth’s land became permanently drier in recent decades, UN scientists warned today in a stark new analysis.Some 77.6% of Earth’s land experienced drier conditions during the three decades leading up to 2020 compared to the previous 30-year period, according to the landmark report from the UN Convention to Combat Desertification (UNCCD).Over the same period, drylands expanded by about 4.3 million km2 – an area nearly a third larger than India, the world’s 7th largest country – and now cover 40.6% of all land on Earth (excluding Antarctica).In recent decades some 7.6% of global lands – an area larger than Canada – were pushed across aridity thresholds (i.e. from non-drylands to drylands, or from less arid dryland classes to more arid classes).Most of these areas have transitioned from humid landscapes to drylands, with dire implications for agriculture, ecosystems, and the people living there. And the research warns that, if the world fails to curb greenhouse gas emissions, another 3% of the world’s humid areas will become drylands by the end of this century. In high greenhouse gas emissions scenarios, expanding drylands are forecast across the Midwestern United States, central Mexico, northern Venezuela, north-eastern Brazil, south-eastern Argentina, the entire Mediterranean Region, the Black Sea coast, large parts of southern Africa, and southern Australia.The report, The Global Threat of Drying Lands: Regional and global aridity trends and future projections, was launched at the 16th conference of UNCCD’s nearly 200 Parties in Riyadh, Saudi Arabia (COP16), the largest UN land conference to date, and the first UNCCD COP to be held in the Middle East, a region profoundly affected by impacts from aridity.“This analysis finally dispels an uncertainty that has long surrounded global drying trends,” says Ibrahim Thiaw, UNCCD Executive Secretary. “For the first time, the aridity crisis has been documented with scientific clarity, revealing an existential threat affecting billions around the globe.” “Unlike droughts—temporary periods of low rainfall—aridity represents a permanent, unrelenting transformation,” he adds. “Droughts end. When an area’s climate becomes drier, however, the ability to return to previous conditions is lost. The drier climates now affecting vast lands across the globe will not return to how they were and this change is redefining life on Earth.”The report by UNCCD Science-Policy Interface (SPI) — the UN body for assessing the science of land degradation and drought — points to human-caused climate change as the primary driver of this shift. Greenhouse gas emissions from electricity generation, transport, industry and land use changes warm the planet and other human activities warm the planet and affect rainfall, evaporation and plant life, creating the conditions that increase aridity.Global aridity index (AI) data track these conditions and reveal widespread change over the decades. Aridification hotspotsAreas particularly hard-hit by the drying trend include almost all of Europe (95.9% of its land), parts of the western United States, Brazil, parts of Asia (notably eastern Asia), and central Africa.Parts of the Western United States and Brazil: Significant drying trends, with water scarcity and wildfires becoming perennial hazards.Mediterranean and Southern Europe: Once considered agricultural breadbaskets, these areas face a stark future as semi-arid conditions expand.Central Africa and parts of Asia: Biologically megadiverse areas are experiencing ecosystem degradation and desertification, endangering countless species.By contrast, less than a quarter of the planet’s land (22.4%) experienced wetter conditions, with areas in the central United States, Angola’s Atlantic coast, and parts of Southeast Asia showing some gains in moisture.The overarching trend, however, is clear: drylands are expanding, pushing ecosystems and societies to suffer from aridity's life-threatening impacts.The report names South Sudan and Tanzania as nations with the largest percentage of land transitioning to drylands, and China as the country experiencing the largest total area shifting from non-drylands into drylands.For the 2.3 billion people – well over 25% of the world’s population – living in the expanding drylands, this new normal requires lasting, adaptive solutions. Aridity-related land degradation, known as desertification, represents a dire threat to human well-being and ecological stability. And as the planet continues to warm, report projections in the worst-case scenario suggest up to 5 billion people could live in drylands by the century’s end, grappling with depleted soils, dwindling water resources, and the diminishment or collapse of once-thriving ecosystems.Forced migration is one of aridity’s most visible consequences. As land becomes uninhabitable, families and entire communities facing water scarcity and agricultural collapse often have no choice but to abandon their homes, leading to social and political challenges worldwide. From the Middle East to Africa and South Asia, millions are already on the move—a trend set to intensify in coming decades.Aridity’s devastating impactThe effects of rising aridity are cascading and multifaceted, touching nearly every aspect of life and society, the report says.It warns that one fifth of all land could experience abrupt ecosystem transformations from rising aridity by the end of the century, causing dramatic shifts (such as forests becoming grasslands and other changes) and leading to extinctions among many of the world’s plants, animals and other life.Aridity is considered the world’s largest single driver behind the degradation of agricultural systems, affecting 40% of Earth’s arable landsRising aridity has been blamed for a 12% decline in gross domestic product (GDP) recorded for African countries between 1990–2015More than two thirds of all land on the planet (excluding Greenland and Antarctica) is projected to store less water by the end of the century, if greenhouse gas emissions continue to rise even modestlyAridity is considered one of the world’s five most important causes of land degradation (along with land erosion, salinization, organic carbon loss and vegetation degradation)Rising aridity in the Middle East has been linked to the region’s more frequent and larger sand and dust stormsIncreasing aridity is expected to play a role in larger and more intense wildfires in the climate-altered future—not least because of its impacts on tree deaths in semi-arid forests and the consequent growing availability of dry biomass for burningRising aridity’s impacts on poverty, water scarcity, land degradation and insufficient food production have been linked to increasing rates of sickness and death globally —especially among children and womenRising aridity and drought play a key role in increasing human migration around the world—particularly in the hyper-arid and arid areas of southern Europe, the Middle East and North Africa and southern Asia. Report marks a turning pointFor years, documenting the rise of aridity proved a challenge, the report states. Its long-term nature and the intricate interplay of factors such as rainfall, evaporation, and plant transpiration made analysis difficult. Early studies produced conflicting results, often muddied by scientific caution.The new report marks a turning point, leveraging advanced climate models and standardized methodologies to deliver a definitive assessment of global drying trends, confirming the inexorable rise of aridity, while providing critical insights into its underlying drivers and potential future trajectory.RecommendationsThe report offers a comprehensive roadmap for tackling aridity, emphasizing both mitigation and adaptation. Among its recommendations:Strengthen aridity monitoringIntegrate aridity metrics into existing drought monitoring systems. This approach would enable early detection of changes and help guide interventions before conditions worsen. Platforms like the new Aridity Visual Information Tool provide policymakers and researchers with valuable data, allowing for early warnings and timely interventions. Standardized assessments can enhance global cooperation and inform local adaptation strategies.Improve land use practicesIncentivizing sustainable land use systems can mitigate the impacts of rising aridity, particularly in vulnerable regions. Innovative, holistic, sustainable approaches to land management are the focus of another new UNCCD SPI report, Sustainable Land Use Systems: The path to collectively achieving Land Degradation Neutrality, available at https://bit.ly/3ZwkLZ3. It considers how land-use at one location affect others elsewhere, makes resilience to climate change or other shocks a priority, and encourages participation and buy-in by Indigenous and local communities as well as all levels of government. Projects like the Great Green Wall—a land restoration initiative spanning Africa—demonstrate the potential for large-scale, holistic efforts to combat aridity and restore ecosystems, while creating jobs and stabilizing economies.Invest in water efficiencyTechnologies such as rainwater harvesting, drip irrigation, and wastewater recycling offer practical solutions for managing scarce water resources in dry regions.Build resilience in vulnerable communitiesLocal knowledge, capacity building, social justice and holistic thinking are vital to resilience. Sustainable land use systems encourage decision makers to apply responsible governance, protect human rights (including secure land access) and ensure accountability and transparency. Capacity-building programmes, financial support, education programmes, climate information services and community-driven initiatives empower those most affected by aridity to adapt to changing conditions. Farmers switching to drought-resistant crops or pastoralists adopting more arid-tolerant livestock exemplify incremental adaptation.Develop international frameworks and cooperationThe UNCCD’s Land Degradation Neutrality framework provides a model for aligning national policies with international goals, ensuring a unified response to the crisis. National Adaptation Plans must incorporate aridity alongside drought planning to create cohesive strategies that address water and land management challenges. Cross-sectoral collaboration at the global level, facilitated by frameworks like the UNCCD, is essential for scaling solutions.Comments“For decades, the world’s scientists have signalled that our growing greenhouse gas emissions are behind global warming. Now, for the first time, a UN scientific body is warning that burning fossil fuels is causing permanent drying across much of the world, too—with potentially catastrophic impacts affecting access to water that could push people and nature even closer to disastrous tipping points. As large tracts of the world’s land become more arid, the consequences of inaction grow increasingly dire and adaptation is no longer optional—it is imperative.” – UNCCD Chief Scientist Barron Orr“Without concerted efforts, billions face a future marked by hunger, displacement, and economic decline. Yet, by embracing innovative solutions and fostering global solidarity, humanity can rise to meet this challenge. The question is not whether we have the tools to respond—it is whether we have the will to act.” – Nichole Barger, Chair, UNCCD Science-Policy Interface“The report’s clarity is a wake-up call for policymakers: tackling aridity demands more than just science—it requires a diversity of perspectives and knowledge systems. By weaving Indigenous and local knowledge with cutting-edge data, we can craft stronger, smarter strategies to slow aridity’s advance, mitigate its impacts and thrive in a drying world.” – Sergio Vicente-Serrano, co-lead author of the report and an aridity expert with Spain’s Pyrenean Institute of Ecology“This report underscores the critical need to address aridity as a defining global challenge of our time. By uniting diverse expertise and leveraging breakthrough technologies, we are not just measuring change—we are crafting a roadmap for resilience. Tackling aridity demands a collaborative vision that integrates innovation, adaptive solutions, and a commitment to securing a sustainable future for all." – Narcisa Pricope, co-lead author, professor of geosciences and associate vice president for research at Mississippi State University, USA.“The timeliness of this report cannot be overstated. Rising aridity will reshape the global landscape, challenging traditional ways of life and forcing societies to reimagine their relationship with land and water. As with climate change and biodiversity loss, addressing aridity requires coordinated international action and an unwavering commitment to sustainable development.” – Andrea Toreti, co-lead author and senior scientist, European Commission’s Joint Research CentreBy the Numbers: Key global trends / projections77.6%: Proportion of Earth's land that experienced drier climates from 1990–2020 compared to the previous 30 years.40.6%: Global land mass (excluding Antarctica) classified as drylands, up from 37.5% over the last 30 years.4.3 million km²: Humid lands transformed into drylands in the last three decades, an area one-third larger than India40%: Global arable land affected by aridity—the leading driver of agricultural degradation.30.9%: Global population living in drylands in 2020, up from 22.5% in 19902.3 billion: People living in drylands in 2020, a doubling from 1990, projected to more than double again by 2100 under a worst-case climate change scenario.1.35 billion: Dryland inhabitants in Asia—more than half the global total.620 million: Dryland inhabitants in Africa—nearly half of the continent’s population.9.1%: Portion of Earth’s land classified as hyperarid, including the Atacama (Chile), Sahara (Africa), Namib (Africa), and Gobi (China/Mongolia) deserts.23%: Increase in global land at "moderate" to "very high" desertification risk by 2100 under the worst-case emissions scenario+8% at "very high" risk+5% at "high" risk+10% at "moderate" riskEnvironmental degradation5: Key drivers of land degradation: Rising aridity, land erosion, salinization, organic carbon loss, and vegetation degradation20%: Global land at risk of abrupt ecosystem transformations by 2100 due to rising aridity55%: Species (mammals, reptiles, fish, amphibians, and birds) at risk of habitat loss from aridity.

Drought, on the other hand, is an anomalous, shorter-term period of water shortage affecting ecosystems and people and often attributed to low precipitation, high temperatures, low air humidity and/or anomalies in wind. While drought is part of natural climate variability and can occur in almost any climatic regime, aridity is a stable condition for which changes occur over extremely long-time scales under significant forcing.

For centuries, rangelands and pastoralist communities have been the backbone of cultures, economies and ecosystems around the world. Covering more than half of the Earth's land surface, these vast landscapes support two billion people and contribute significantly to global food security and climate resilience. Yet they have remained largely invisible in international policy discussions, slowly degrading under the pressures of climate change, unsustainable land use and economic expansion. At UNCCD COP16 in Riyadh, nations took a decisive step by adopting a decision on rangelands and pastoralists, marking an unprecedented commitment to protect these critical ecosystems and the people who depend on them. This commitment represents a fundamental shift, placing rangelands alongside forests and wetlands in global conservation efforts and ensuring that their role in climate resilience, biodiversity conservation and food security is fully recognized. Why rangelands are more important than ever Rangelands and grasslands provide one-sixth of the world's food supply and store nearly one-third of the planet's carbon stocks in their deep-rooted soils. They are vital to smallholder herders, farmers and indigenous communities, yet more than 50 per cent of these ecosystems are now degraded. As Ibrahim Thiaw, Executive Secretary of the United Nations Convention to Combat Desertification (UNCCD), warns, their decline is often overlooked: "When a forest is destroyed, the loss is visible and causes immediate concern. But rangeland degradation is silent, often unnoticed and undervalued." He emphasizes the urgent need for global action to protect these landscapes before it is too late. Beyond their economic significance, healthy rangelands stabilize soil, prevent erosion, regulate water cycles, enhance biodiversity, and store carbon – essential functions in the fight against climate change. Yet, despite their immense ecological value, these landscapes have historically received far less attention and funding than forests and wetlands. Recognizing this oversight, the United Nations General Assembly has declared 2026 as the International Year of Rangelands and Pastoralists (IYRP), a global initiative designed to highlight the indispensable contributions of rangelands and pastoralist communities to our planet’s health and economies. A landmark decision at COP16 For the first time, UNCCD Parties adopted a decision to promote the sustainable management, restoration and conservation of rangelands – vast ecosystems used for grazing – ahead of COP17, which will be hosted by Mongolia in 2026. Countries have pledged to improve pastoralists' land rights by aligning with international guidelines, strengthening legal protections and ensuring access to rangelands. The decision also emphasizes the value of Indigenous and local knowledge in sustainable land management, recognizing the role of traditional pastoral practices in conserving these ecosystems for future generations. Commitments were made to mobilize public-private partnerships, establish biodiversity credits and develop innovative financing models to ensure long-term investment. This pivotal shift ends decades of neglect and places rangelands at the centre of global sustainability efforts. It aligns with the Kunming-Montreal Global Biodiversity Framework and the UN Decade of Ecosystem Restoration and strengthens their integration into national biodiversity and climate strategies and action plans. With Mongolia set to host UNCCD COP17 in 2026, the global community has a unique opportunity to cement rangelands as a key focus of environmental policy. Plans are already underway to develop a UNCCD Flagship Initiative on Rangelands, which will foster international cooperation, secure large-scale funding for restoration, and facilitate knowledge sharing between scientists and pastoral communities. However, systemic challenges remain. Conflicting land use policies, economic pressures and a lack of formal recognition of pastoralists' rights continue to threaten rangeland sustainability. Many pastoralist communities face displacement due to land conversion, mining and large-scale agricultural projects that prioritize short-term economic gains over long-term ecosystem health. Addressing these issues requires an integrated approach that combines scientific research, policy reform and traditional land management. Translating commitments into action “The commitments at UNCCD COP16 mark a turning point, but success depends on sustained collaboration. Governments must work closely with pastoralists and livestock value chain agents, conservation groups and financial institutions, to scale up investment through sustainable financing and innovative tools.” said Enrique Michaud co-chair of the IYRP Global Alliance. "Securing pastoralists' land rights is crucial to prevent displacement and conflict, to ensure access to their traditional rangelands and to fortify the ecosystem services they provide." Sustainable rangeland and land-use planning must balance conservation efforts with the economic realities of pastoral livelihoods, promoting land management strategies that maintain ecosystem health while supporting local economies. Rangeland conservation must also be fully integrated into national and global climate adaptation strategies to ensure that these landscapes contribute to long-term resilience to climate change and desertification. Ensuring rangeland sustainability is not just an environmental imperative – it is a necessity for climate security, food sovereignty and cultural preservation. As UNCCD Parties and partners prepare for COP17, the momentum generated at COP16 must be translated into real action. About UNCCD The United Nations Convention to Combat Desertification (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. https://unccd.int About the International Year of Rangelands and Pastoralists On the initiative of Mongolia, the United Nations General Assembly has designated 2026 the International Year of Rangelands and Pastoralists (IYRP 2026) to enhance rangeland management and the lives of pastoralists. With this declaration, UN Member States are called upon to invest in sustainable rangeland management, to restore degraded lands, to improve market access by pastoralists, to enhance livestock extension services, and to fill knowledge gaps on rangelands and pastoralism. The IYRP 2026 will coincide with the UNCCD COP17 to be hosted by Mongolia. https://iyrp.info

To what extent are a country’s economy, people, and infrastructure able to cope with drought and how can they do better? That is what the latest initiative of IDRA looks to answer, as 75 per cent of Earth’s land has become permanently drier in the last three decades and drought is driving forced displacement, disrupting shipping and hampering food and energy production around the world.The International Drought Resilience Observatory (IDRO), the first global AI-driven platform for proactive drought management, unveiled its prototype at the 16th Conference of the Parties (COP16) of the UN Convention to Combat Desertification (UNCCD) in Riyadh, which laid the groundwork for a future global drought regime.As the tool enters its final development phase ahead of the next UN land conference, which will take place in Mongolia in 2026, IDRO developers and partners break down what sets the Observatory apart, how it fits with existing drought-related initiatives, and why it matters for climate change adaptation.What kind of insights does IDRO provide?IDRO sheds light on the capacity of territories to anticipate, prepare for, and adapt to drought from various perspectives —built environments, natural environments, communities, and the economy. By selecting different variables, users from the global to the local level can generate visualizations to understand where the pain points are and set priorities for action.“With IDRO, authorities and land and water managers will be able to analyze and visualize key drought resilience indicators as the basis for better decisions,” says UNCCD Senior Advisor Edgar Gutiérrez-Espeleta.Importantly, users needn’t be specialists to use, and draw value from, the tool, which can support interventions across global, regional, country, and local scales.Why do we need an International Drought Resilience Observatory?“We must move from merely assessing drought risks towards building resilience,” says Andrea Toreti, senior scientist at the European Commission’s Joint Research Centre (EC- JRC), who coordinates the Copernicus European and Global Drought Observatories. “This is precisely IDRO’s added value: helping to quantify and evaluate the drought resilience status of a place to inform action on the ground.”The confirmation of 2024 as the warmest year on record highlights the growing urgency to turn science and data into policies and policies into action.“Simply put, we cannot adapt to climate change without building drought resilience,” says Roger Pulwarty, Senior Scientist at the Physical Sciences Laboratory of the US National Oceanic and Atmospheric Administration (NOAA). State Secretary of Environment of Spain Hugo Morán, UNCCD Executive Secretary Ibrahim Thiaw, Deputy Minister for Environment of Saudi Arabia Osama Faqeeha, Minister of Environment and Ecological Transition of Senegal Daouda Ngom, and European Commissioner for Environment, Water Resilience and a Competitive Circular Economy Jessika Roswall, during the IDRO presentation at COP16 in December 2024.What unique value does IDRO add to existing drought databases and tools?In the past decade, experts have produced a wealth of data, indicators and metrics on drought and have advocated for a shift in emphasis from response to preparedness. However, the breadth and complexity of this information and the fact that it is scattered means it can be hard for busy decision-makers to use it.IDRO will draw on the best available data globally —including NASA’s and Copernicus’— to answer queries in a format that non-specialists can easily assimilate.“IDRO will package complex drought resilience information into accessible, customizable, and highly actionable formats, unlocking a world of possibilities in terms of assessing priorities, targeting investments, and monitoring progress,” says Hugo Morán, State Secretary of Environment of Spain, which co-chairs IDRA.Who is leading the development of IDRO?IDRO is an initiative of the International Drought Resilience Alliance (IDRA), a global coalition of more than 70 countries and organizations hosted by the UNCCD.The creation of the Observatory is overseen by the IDRA secretariat in collaboration with the Yale Center for Ecosystems + Architecture, which acts as a developer, and top experts from governmental, non-governmental, multilateral, and research organizations from around the world.At a COP16 event on IDRO, Executive Secretary of UNCCD Ibrahim Thiaw pointed out the systemic nature of drought and the need to tackle it together: “We can only achieve meaningful results by joining forces; IDRO is a perfect example of the collaborative mindset we require to protect people from impending and future droughts.”The Minister of Environment and Ecological Transition of Senegal Daouda Ngom, who co-chairs IDRA, also welcomed the development of the Observatory: “It reaffirms our joint commitment to making drought resilience a cornerstone of sustainable development and international cooperation.”What initiatives does IDRO build on?The Drought Initiative, launched by UNCCD in 2018, has already supported more than 70 countries in creating national drought plans and improving the technical and institutional capacity to enhance drought management. Additionally, it put together a toolbox that stakeholders can use to boost the resilience of people and ecosystems to drought.How does IDRO relate to initiatives like the Riyadh Drought Partnership?Unveiled at UNCCD COP16, the Riyadh Global Drought Resilience Partnership is a financial facility launched by Saudi Arabia —an IDRA member since 2024— to support 80 of the world’s most vulnerable countries in preparing for drought.IDRA, which is currently focused on mobilizing political will and developing innovative tools like IDRO, is proud to have inspired the Partnership and the Arab Coordination Group to raise USD 12.15 billion for the land and drought agenda, as announced during COP16.“IDRO will provide critical information to vulnerable communities and synergize with the Riyadh Partnership,” said Deputy Minister for Environment of Saudi Arabia Osama Faqeeha at an IDRO event at the UN conference.What is next for IDRO?IDRA is convening leading drought experts and allies to fine tune suitable environmental and social indicators for drought resilience; further develop the functionalities of the Observatory, which harnesses remote-sensing data and AI; and enhance data collection and visualization. The final version of IDRO, with all its functionalities, is expected to launch at UNCCD COP17 in Mongolia in 2026.

Riyadh, Saudi Arabia, 14 December — After two weeks of intense negotiations on how to tackle land degradation, desertification and drought, the largest and most inclusive United Nations land conference wrapped up in Riyadh, Saudi Arabia.The nearly 200 countries convening at the 16th Conference of the Parties (COP16) to the United Nations Convention to Combat Desertification (UNCCD) committed to prioritize land restoration and drought resilience in national policies and international cooperation as an essential strategy for food security and climate adaptation. Nations also made significant progress in laying the groundwork for a future global drought regime, which they intend to complete at COP17 in Mongolia in 2026. In the meanwhile, more than USD 12 billion were pledged to tackle desertification, land degradation and drought around the world, especially in the most vulnerable countries.Among the main agreements reached at COP16 were the creation of a Caucus for Indigenous Peoples and a Caucus for Local Communities to ensure that their unique perspectives and challenges are adequately represented; a continuation of the Convention’s Science-Policy Interface to strengthen science-based decision-making, and the mobilization of private sector engagement under the Business4Land initiative.COP16 was the largest and most inclusive UNCCD COP to date: it attracted more than 20,000 participants, around 3,500 of them from civil society, and featured more than 600 events as part of the first Action Agenda to involve non-state actors in the work of the Convention.In a prepared statement, United Nations Deputy Secretary-General Amina J. Mohammed emphasized “Our work does not end with the closing of COP16. We must continue to tackle the climate crisis—it is a call to action for all of us to embrace inclusivity, innovation, and resilience. Youth and Indigenous peoples must be at the heart of these conversations. Their wisdom, their voices, and their creativity are indispensable as we craft a sustainable future with renewed hope for generations to come.”In his closing remarks, COP16 President, Saudi Arabia’s Minister of Environment, Water and Agriculture Abdulrahman Alfadley, said the meeting marked a turning point in raising international awareness of the pressing need to accelerate land restoration and drought resilience.“The Kingdom’s hosting of this important conference reflects its ongoing commitment to environmental issues and sustainable development. It reaffirms its dedication to working with all parties to preserve ecosystems, enhance international cooperation to combat desertification and land degradation, and address drought. We hope the outcomes of this session will lead to a significant shift that strengthens efforts to preserve land, reduce its degradation, build capacities to address drought, and contribute to the wellbeing of communities around the world.”Addressing COP16 closing plenary, Under-Secretary-General and UNCCD Executive Secretary Ibrahim Thiaw stated: “As we have discussed and witnessed, the solutions are within our grasp. The actions we took today will shape not only the future of our planet but also the lives, livelihoods, and opportunities of those who depend on it.”He further emphasized a significant shift in the global approach to land and drought issues, highlighting the interconnected challenges with broader global issues such as climate change, biodiversity loss, food security, forced migration, and global stability.Financial needs and pledgesDuring the Conference, participants heard that UNCCD estimates that at least USD 2.6 trillion in total investments are needed by 2030 to restore more than one billion hectares of degraded land and build resilience to drought. This equals USD 1 billion in daily investments between now and 2030 to meet global land restoration targets and combat desertification and drought.New pledges for large-scale land restoration and drought preparedness were announced, such as the Riyadh Global Drought Resilience Partnership which attracted USD 12.15 billion to support 80 of the world’s most vulnerable countries in building their resilience to drought, including a USD 10 billion pledge from the Arab Coordination Group.The Great Green Wall (GGW), an African-led initiative to restore 100 million hectares of degraded land, also mobilized EUR 11 million from the Italian Government for landscape restoration in the Sahel and EUR 3.6 million from the Austrian Government to strengthen the coordination and implementation of the initiative across 22 African countries. The drive is part of the GGW Accelerator, a UNCCD-supported effort to achieve the ambitions for a greener, more prosperous Sahel.Additionally, the United States and several partner countries and organizations announced total investments of nearly USD 70 million to advance the Vision for Adapted Crops and Soils (VACS). The initiative looks to build resilient food systems grounded in diverse, nutritious, and climate-adapted crops grown in healthy soils.The first-ever UNCCD COP in the Middle East and North Africa provided an opportunity to shine a light on the specific challenges facing the region and bring to the fore innovative solutions to land degradation and drought.The Kingdom of Saudi Arabia announced five new projects valued at USD 60 million to ramp up climate and environmental efforts as part of the Saudi Green Initiative. The UNCCD COP16 Presidency also announced the launch of an international sand and dust storm monitoring initiative. This effort, part of a regional early warning system, aims to complement existing efforts overseen by the World Meteorological Organization (WMO).The International Drought Resilience Observatory (IDRO), the first global AI-driven platform to help countries assess, and enhance, their capacity to cope with harsher droughts. This innovative tool is an initiative of the International Drought Resilience Alliance (IDRA), which Saudi Arabia joined earlier this year. Greater voice for Indigenous Peoples and other non-state actorsIn a landmark decision, Parties requested the creation of a Caucus for Indigenous Peoples and a Caucus for Local Communities. The objective is to ensure that their unique perspectives and priorities are adequately represented in the work of the Convention. The declaration ‘Sacred Lands’, presented during the inaugural Indigenous Peoples’ Forum at a UNCCD COP, underscored the role of Indigenous Peoples in sustainable resource management and called for greater involvement in global land and drought governance, including through participation in land restoration efforts.“Today, history has been made”, said Indigenous People representative Oliver Tester from Australia. “We look forward to championing our commitment to protect Mother Earth through a dedicated Caucus, and leave this space trusting that our voices be heard.”COP16 also saw the biggest youth participation to date, building on the UNCCD Youth Engagement Strategy and Action Plan, that seeks to give youth a more prominent role in land and drought negotiations and action, and provide technical and financial support for youth-led initiatives.On the gender front, countries underscored the need to pay special attention to all forms of discrimination faced by women and girls when designing and implementing policy and programmes related to land degradation and drought.In recognition of the important role of the private sector, which currently contributes only 6% of financing towards land restoration and drought resilience, Parties have mandated the UNCCD Secretariat and the Global Mechanism to mobilize private sector engagement under the Business4Land initiative. The decision emphasizes the critical role of private sector advocacy, environmental, social, and governance (ESG) strategies, and sustainable finance in addressing DLDD challenges. The decision comes after the Business4Land Forum, which brought together the largest-ever number of private sector participants at a UNCCD COP — more than 400— from industries like finance, fashion, agri-food, and pharmaceuticals.Stronger science on land and droughtAcknowledging the role of science as the foundation for sound policies, the Parties agreed on the continuation of UNCCD’s Science-Policy Interface (SPI), which was created at COP11 in 2013 to translate scientific findings into recommendations for decision-makers. At COP16, for instance, the SPI presented definitive evidence that three quarters of the Earth’s ice-free surface have become permanently drier in the past 30 years, with a predicted five billion people living in drylands by 2100, showing the urgency to take action.A new UNCCD report, The Global Threat of Drying Lands: Regional and global aridity trends and future projections, revealed that some 77.6% of Earth’s land has experienced drier conditions since the 1990s compared to the previous 30-year period. Over the same period, drylands — an arid area with low rainfall— expanded by about 4.3 million km2 equal to an area nearly a third larger than India, the world’s 7th largest country. Drylands now cover 40.6% of all land on Earth excluding Antarctica.Seven of nine planetary boundaries are negatively impacted by unsustainable land use, highlighted the UNCCD report Stepping back from the precipice: Transforming land management to stay within planetary boundaries, produced in collaboration with the Potsdam Institute for Climate Impact Research, which explains how land degradation is undermining Earth’s capacity to sustain a growing human population. The report reiterates that agriculture accounts for 23% of greenhouse gas emissions, 80% of deforestation, and 70% of freshwater use, and calls for an urgent land use transition to step away from the precipice.According to UNCCD’s newly released World Drought Atlas and Economics of Drought Resilience reports, droughts affect the livelihoods of 1.8 billion people worldwide, pushing already vulnerable communities to the brink. They also cost an estimated USD 300 billion per year, threatening key economic sectors such as agriculture, energy and water.From Riyadh to MongoliaFor the first time, UNCCD Parties made a decision encouraging the sustainable management, restoration and conservation of rangelands — vast ecosystems used for grazing — ahead of COP17, to be hosted by Mongolia in 2026 during the International Year of Rangelands and Pastoralists. These ecosystems cover half of the Earth’s terrestrial surface and are the dominant land use in the world’s drylands, but have long been overlooked and are disappearing faster than rainforests.The degradation of rangelands threatens one-sixth of global food supplies, potentially depleting one-third of the Earth's carbon reserves. Some two billion people who live in pastoral areas are among the world’s most vulnerable in the face of desertification, land degradation and drought.ENDNOTESMedia inquiries:For media enquiries, please contact the UNCCD Press Office at press@unccd.int or unccd@portland-communications.comCOP16 decisions are available here: https://www.unccd.int/cop16/official-documentsAbout UNCCDThe United Nations Convention to Combat Desertification (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.About COP16The Conference of the Parties (COP) was established by the Convention as its main decision-making body. It is made up of UNCCD’s 197 Parties (196 countries and the European Union) and is responsible for guiding the Convention so that it can respond to global challenges and national needs. UNCCD COP16 will be a landmark event to raise global ambition and accelerate action on land and drought resilience through a people-centred approach. Coinciding with the Convention’s 30th anniversary, UNCCD COP16 was the first major UN conference hosted by the Kingdom of Saudi Arabia. It was also the first time a UNCCD COP was held in the Middle East and North Africa (MENA) region, which knows firsthand the impacts of desertification, land degradation and drought.
