Disaster Risk Management

Climate, weather, and water-related (hydrometeorological) disasters, such as cyclones, droughts, and floods, account for the largest number of natural disasters recorded worldwide and affect more people than any other type of natural hazard. According to the Centre for Research on the Epidemiology of Disasters, between 1994 and 2013, drought, extreme temperatures, floods, and storms resulted in approximately 600,000 deaths, affected more than 3 billion people, and caused an estimated $2 trillion in economic damages. In the last four decades, the number of reported hydrometeorological disasters increased nearly fivefold, from approximately 750 incidents between 1971 and 1980 to 3,500 events between 2000 and 2010. Direct impacts of climate-related disasters include death and injury, loss of livelihoods, resource scarcity, damage to infrastructure and environment, and reduced or altered access to critical, life-sustaining services.

Hydrometeorological hazards become disasters when they affect communities and countries that are exposed, vulnerable, and lack the capacity to cope with them. Disaster Risk Reduction (DRR) activities aim to reduce vulnerabilities and exposure to hydrometeorological events while increasing capacities at all levels. Early warning systems are a good example of a DRR activity. An early warning system that provides timely, accurate, and reliable information can give decision-makers and the public the time they need to act. Improved disaster preparedness at all levels of government and communities, combined with early warning systems, can guide communities to take actions that will save lives and property and help them be self-reliant.

In December 2019, Typhoon Kammuri flooded parts of Legazpi City, one of the biggest natural hazard hotspots in the country. Earlier that year, USAID had helped the local water district develop an emergency preparedness plan for maintaining and restoring water services when disasters strike.
Natural river shifting and human changes to the landscape can drastically redirect floodwaters from year to year, making anticipating flood paths extremely tricky. Because rising sea surface temperatures are fueling more frequent and severe rainfall extremes, faster flood mapping is in high demand.
Climate impacts social and economic development across sectors, in numerous ways. Each sector also has unique opportunities to contribute to climate solutions. USAID integrates climate change in development programming across a variety of technical fields.
