Ecological Drought Across the Country

Water resources are critical for ecosystems, agriculture, and communities, and potential climate impacts to hydrologic budgets and cycles are arguably the most consequential to society. Apart from precipitation, evapotranspiration makes up the most significant component of the hydrologic budget. Evapotranspiration is a primary metric for identifying Ecological Drought, a deficit in water availability that negatively impacts ecosystems and ecosystem services. Through an agreement between the USGS Earth Resources Observation and Science (EROS) Center Land Cover Monitoring, Assessment and Projection (LCMAP) program and the North Central CASC, Dr. Senay works to integrate and apply remotely sensed data for eco- and agro-hydrologic modeling. He promotes and advances the use of satellite-derived multi-scale evapotranspiration products by the key stakeholders in the irrigation and water resources community for climate adaptation planning.
