Advancing Drought Understanding, Monitoring and Prediction

In order to address gaps in the understanding, monitoring, and prediction of drought and improve our Nation’s ability to prepare for impacts, NOAA’s Modeling, Analysis, Predictions, and Projections (MAPP) program — in partnership with the National Integrated Drought Information System (NIDIS) — is funding 12 new three-year projects. These competitively-funded projects involve $4.2 million in grants and $1.8 million in other awards (for a total of $6.0 million).
Drought has and continues to cause serious social and economic impacts throughout the United States. According to the NOAA National Centers for Environmental Information, a single drought event costs the U.S. about $9.4 billion on average1. From agricultural and drinking water supplies to infrastructure, health, ecosystems, and energy costs, drought negatively affects myriad sectors and people. Through the new National Drought Resilience Partnership, as well as NIDIS and its regional Drought Early Warning Systems (DEWS), NOAA, working with interagency and academic colleagues, strives to improve the country’s capacity to manage drought-related risks and mitigate impacts by providing the best available information and tools. Building on the NIDIS example, an emerging international effort has begun to develop similar capabilities through a Global Drought Information System. In addition, NOAA’s Drought Task Force (DTF) has contributed significantly to the goals of the World Climate Research Program’s Climate Variability and Predictability and Global Energy and Water Cycle Exchanges programs.
The newly selected projects will build on the previous NOAA DTFs’ accomplishments during a third term of the Drought Task Force, which will be active from 2017 to 2020. Research topics will focus on improving understanding of sources of predictability, advancing the capability to model processes related to drought, developing new national monitoring and forecast products, and advancing operational drought monitoring and prediction systems.
