Freshwater

"Water that contains less than 1,000 milligrams per liter (mg/L) of dissolved solids; generally, more than 500 mg/L of dissolved solids is undesirable for drinking and many industrial uses." (U.S. Geological Survey, 2019)

This website includes tools and resources for developing basin report cards. It includes reports that incorporate satellite imagery to measure environmental indicators and change over time.

With the University of Maryland Center for Environmental Science (UMCES), we are developing, packaging, and sharing a process that helps stakeholders create science-based report cards in their own basins with the right buy-in on-the-ground and credibility globally, so they can better manage resources for the protection of fresh water they depend upon.

Interview with Prof. Hesham El-Askary

Photo of Prof. El-Askary
Prof. Hesham El-Askary works at Chapman University in the Earth Systems Science Data Solutions (ESsDs) lab. Here, he supervises students on the use of satellite earth observations for topics including agriculture, water resources, air quality and climate action, and makes use of Artificial Intelligence (AI) and Machine Learning (ML). Prof. El-Askary is researching natural and anthropogenic pollution’s influence on the environment and is particularly interested in the concept of “glocal” impact—how what’s happening globally in terms of climate affects us locally. He believes that one of the biggest challenges in implementing sustainable water management is the lack of data to monitor progress, and advocates for space technologies to mitigates this shortage.
