Riyadh, Saudi Arabia — As record-breaking droughts are becoming a new normal around the globe, the UN Convention to Combat Desertification (UNCCD) and the European Commission Joint Research Centre (JRC) launch the most comprehensive global publication on drought risks and solutions as an urgent wake-up call for world leaders and citizens.
The landmark new World Drought Atlas depicts the systemic nature of drought risks through dozens of maps, infographics, and case studies. It illustrates how drought risks are interconnected across sectors like energy, agriculture, river transport, and international trade and how they can trigger cascading effects, fueling inequalities and conflicts and threatening public health.
Co-produced with Cima Research Foundation (Italy), Vrije Universiteit Amsterdam (The Netherlands), and the UN University Institute for Environment and Human Security (Germany), its publication comes as UNCCD's 197 member states, meeting in Riyadh, negotiate how to build humanity's resilience to harsher droughts.
Droughts are one of the world's most costly and deadly hazards and are on track to affect 3 in 4 people globally by 2050. However, many countries and sectors are still failing to prepare for them through the right actions, policies, investments, and incentives.
"The World Drought Atlas challenges governments, business leaders, and policy makers at all levels to radically rethink how they make decisions and manage drought risk," said UNCCD Executive Secretary Ibrahim Thiaw. "I call on all nations, and in particular the Parties to the UNCCD, to take the findings of the Atlas seriously. At UNCCD COP16, Parties could change the course of history towards drought resilience. Let us seize the moment with the knowledge that the Atlas provides a path for a more resilient future for all."
The Atlas underscores the need for national drought plans and international cooperation to keep communities, economies, and ecosystems afloat in the face of harsher events. Additionally, it offers guidance for proactive and prospective drought management and adaptation across sectors and governance levels.
Drought impacts are typically less visible, and attract less attention, than sudden events like floods and earthquakes. That is particularly true for the effects on ecosystems, which tend to be neglected in national drought plans despite their crippling impacts on economies and communities. But fast-onset droughts, known as flash droughts, more intense droughts—and more readily apparent impacts—are also becoming commonplace.
HIGHLIGHTS FROM THE ATLAS
Impacts of human-made droughts
The World Drought Atlas explains how worsening drought risks are linked to human activities and then delves into the impacts of drought in five key areas—water supply, agriculture, hydropower, inland navigation, and ecosystems.
Droughts can reduce hydropower generation, leading to higher energy prices or power outages, and can disrupt international trade due to low water levels that hinder inland waterway transportation, as seen with the Panama Canal.
On the nature front, the Atlas notes that while droughts pose a threat to ecosystems, greater biodiversity can mitigate drought impacts, meaning that promoting biodiversity is important to build drought resilience and vice versa.
The food-land-water nexus is another major focus of the Atlas, since agriculture accounts for around 70% of freshwater use globally, and is also seriously impacted by drought.
The publication explores how the agricultural products that reach our plates through global supply chains can worsen the effects of droughts and create water-stress in the countries where they are produced through virtual water transfers. Small-scale farmers and marginalized groups are particularly vulnerable due to disparities in water access and resources needed to build resilience to drought.
The Atlas also shows how drought risks are interconnected and why their effects span across sectors. Countries reliant on hydropower for electricity, for instance, may face power outages during droughts. If this happens during a heatwave, it can result in hospitalizations and deaths as people cannot use fans or air conditioning to cool their homes.
Lessons from recent droughts
The Atlas features 21 case studies from around the world, underscoring that no country—whatever its size, GDP, or latitude—is immune to drought and all can better prepare for it.
For example, the publication highlights impacts and lessons learned from recent droughts on the Great Plains of the US, in the city of Barcelona in Spain, and in the Yangtze River basin in China and explores drought impacts across the Central American Dry Corridor, the Indian subcontinent, and the Horn of Africa. Other case studies highlight the particular needs, resources, and perspectives of Indigenous communities when it comes to preparing for drought.
Droughts have increased by 29% since the year 2000 due to climate change and the unsustainable management of land and water resources. The UN considers human-made drought an emergency on a planetary scale, but notes that drought risks can be tackled with the right actions, policies and investments.
How to build drought resilience
The Atlas describes concrete measures and pathways to manage, reduce, and adapt to systemic drought risks; underscores the co-benefits of these actions for different sectors; and showcases best practices from different regions.
The measures highlighted in the Atlas fall into three categories: governance (e.g. early warning systems, microinsurance for smallholder farmers, pricing schemes for water usage); land-use management (e.g. land restoration and agroforestry); and the management of water supply and use (e.g. wastewater reuse, managed groundwater recharge and conservation.)
As highlighted by the Atlas, the Secretariat of the UNCCD, its Communities of Learning and Practice, the International Drought Resilience Alliance (IDRA), the European Commission Joint Research Centre, the regional and global networks and partner institutions listed in the publication, and communities themselves can develop and provide the necessary knowledge, tools, and support to transform science into policy and policy into drought resilience action today
"The Atlas is a powerful new resource to build political momentum for proactive drought risk management ahead of UNCCD COP16 in Riyadh. We already have the knowledge and tools to build our resilience to harsher droughts. It is now our collective responsibility, and in our best interest, to take action for a drought-resilient future," sums up Hugo Morán, Secretary of State of Environment of Spain, which co-chairs the International Drought Resilience Alliance (IDRA) together with Senegal.
