Las sequías en las Américas: prioridades regionales, sistemas de alerta temprana y desarrollo sostenible

The document details a multi-stakeholder event focused on drought resilience in the Americas, highlighting the critical role of Early Warning Systems (EWS) and the need for better integration between scientific research and public policy. It discusses global trends in drought frequency, regional climate impacts in Latin America and the Caribbean, and specific case studies such as the SISSA project in the Southern Cone and water management at the Yacyretá hydroelectric plant. The report emphasizes the importance of scientific diplomacy, innovative financing models involving the private sector, and the necessity of co-designing climate services with end-users to ensure sustainability and effectiveness.

• Global drought frequency has increased by 29% since 2000, and it is projected that global freshwater demand will exceed supply by 40% by 2030.
• The economic cost of drought-related damages between 2000 and 2019 is estimated at 128 billion dollars, though cascading effects may bring the actual annual figure closer to 307 billion dollars.
• In 2024, severe climate events in Latin America and the Caribbean included the total loss of glaciers in Venezuela, a 21-day heatwave in Mexico causing 90 deaths, and devastating wildfires in Valparaíso, Chile, resulting in over 130 deaths.
• Early Warning Systems (EWS) for droughts differ from those for floods because droughts develop over longer periods and have different spatial scales, requiring long-term risk assessment and trend monitoring rather than just rapid communication.
• The Drought Information System for the South of South America (SISSA) utilizes co-design and co-production with national working groups to translate climate information into practical sectoral knowledge for agriculture, hydroelectric energy, and inland waterway transport.
• Drought-induced low water levels at the Yacyretá hydroelectric plant required complex regional negotiations between Paraguay, Argentina, and Brazil to balance navigation needs (150,000 tons of cargo for Paraguay) with drinking water supply and environmental protection.
• There is a persistent gap between academic research and operational application in national meteorological services; for example, Chile shifted toward localized, user-based services after finding that 'one-size-fits-all' products were ineffective.
• Sustainable resilience requires moving beyond public investment to include private sector co-financing, such as climate-resilient credit lines and agricultural insurance linked to measurable resilience criteria.
