Total Running Time: 

USAID is helping countries adapt to climate change, from extreme storms already striking coastal communities, to rises in temperature and changes in rainfall patterns that are shifting agricultural zones.  Adaptation programs in more than 30 of the world's most-vulnerable countries—including small island states and glacier-dependent areas—are helping build resilience to these threats.
USAID assistance facilitates access by governments and other stakeholders to the latest climate and weather data to support decision-making, long-range planning and the development of climate-resilient policies and institutions.  Such information is vital, whether deciding where to site new urban infrastructure or in developing crop varieties that will thrive in different climate conditions. Adaptation funds are also helping communities prepare for more frequent extreme weather events through early warning systems.  Other efforts are lowering communities’ risk from droughts or floods, such as through index insurance or by diversifying traditional livelihoods that are particularly vulnerable to climate impacts.

Climate Smart Cities
USAID helps increase cities' capacity to finance and build public infrastructure and services, engaging diverse local, national, public and private stakeholders. Programs address incentives for and challenges to mobilizing finance, and improve urban services for climate-resilient, low-emission and sustainable economic development.
Climate Change, Migration and Conflict
USAID’s Office of Conflict Management and Mitigation and the Wilson Center's Environmental Change and Security Program developed a guide on the nexus between climate change, migration and conflict. The guide provides background on relevant literature and an in-depth analysis of the high-profile cases of Darfur and Syria to discern policy-relevant lessons from the latest research.
SERVIR-Global partners with leading regional organizations around the globe, providing NASA satellite data and international collaborators who collectively develop useful information, tools and training for national governments and local communities. This joint USAID and NASA initiative helps 37 countries in four regions to address climate change and other challenges related to water, agriculture, disasters, and land use. Activities span Eastern and Southern Africa, the Hindu Kush-Himalaya, Mekong, and Central America regions.
Index-based Livestock Insurance
Ethiopia’s Index-based Livestock Insurance (IBIL) program is providing an innovative micro-insurance product for pastoralists facing risk from extreme drought. The vegetation-based index relies on satellite data to identify drought in a region where few weather stations exist. By purchasing insurance, pastoralists transfer risk to insurance companies, thus buffering against the devastating loss of food and income associated with more-frequent and severe drought.
Drought Forecast & Alert System
Jamaica’s Drought Forecast & Alert System supports farmers in adjusting planting and harvesting schedules to save crops, investments, and livelihoods important to the national economy. The system combines recent rainfall measured by Jamaica’s weather stations with seasonal rainfall forecasts and delivers vital information to farmers via free texts and bulletins. Early success in Jamaica facilitated expanding the system to the broader Caribbean basin where it now serves 40 million residents.
Indonesia Urban Water, Sanitation and Hygiene
Indonesia’s Urban Water, Sanitation and Hygiene (IUWASH) project has given nearly 2 million people access to safe water and is improving sanitation. With climate change extending dry seasons and making rainfall more unpredictable in Indonesia, IUWASH has also teamed with The Coca-Cola Foundation to recharge groundwater aquifers and replenish streams. They have built more than 3,200 infiltration ponds, which trap rainwater that would otherwise be lost as runoff.
