The National Drought Mitigation Center’s mission is to reduce the effects of drought on people, the environment and the economy by researching the science of drought monitoring and the practice of drought planning. We collaborate with and learn from decision-makers at all levels – individual ranchers, communities, regions, watersheds, tribes, states, countries – across the US and around the world. We organize and present workshops, writeshops and other capacity-building activities, in close cooperation with local partners.
