Eco-Scarcity

Water Reliability & Scarcity

Water reliability and scarcity data provide estimates of water supply and demand and the degree to which water demand may exceed supply in the future, based on past trends and climate change. Most of the data directly assess supply available for human uses but can also be applied to evaluate threats to water-dependent ecosystem services. For example, trends in stream baseflow by location can be compared to critical habitat for threatened freshwater fish species to assess the risk of habitat degradation.
