Historically, drought has been viewed in terms of its agricultural, hydrological, and socioeconomic impacts. How drought affects ecosystems - and the services they provide human communities - is often not discussed. In response, the U.S. Geological Survey's National Climate Adaptation Science Center (NCASC) initiated a national-scale effort that’s addressing this gap in drought research. A new concept – ecological drought – was defined as part of this effort. This geo-narrative explains the concept of ecological drought, and highlights the research and products that were initiated as part of this effort.
