Schematic figure of the processes included in the Community Water Model. Credit: IIASA ENLARGE The growing global population and continued economic development will likely require a significant increase in water demand, especially in developing regions. At the same time, climate change is already having global, regional, and local impacts on […]

Organic matter in nebula could be the source of terrestrial water. Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA) Scientists have found the interstellar organic matter could produce an abundant supply of water by heating, suggesting that organic matter could be the source of terrestrial water. There remains a number of […]

A laser-etched, energy absorbing, water wicking metal surface, continually angled directly at the sun, provides a cheap, efficient way to purify water from sunlight. The technology was developed by the lab of Chunei Guo at the University of Rochester. Credit: H.M. Cao/University of Rochester By etching metal with ultrashort laser […]

Two satellite images show vegetation change from fog in two areas of the Namib desert. The left image shows the areas during periods of lower fog; the right image shows the areas during periods of higher fog. Greener areas inside the squares indicate vegetation greening.

Percentages represent fraction of the global cultivated area in each category. Shading indicates croplands affected by blue water scarcity (BWS) that can be sustainably irrigated with deficit irrigation. These areas are then reclassified as suitable for sustainable irrigation [i.e., with no blue water scarcity (NO BWS)], considering different deficit irrigation […]

A new U.S. Supreme Court ruling puts groundwater science at the center of decisions about how to regulate water pollution. Today, in a closely watched case with extensive implications, the court ruled 6 to 3 that the federal Clean Water Act applies to pollution of underground water that flows into nearby lakes, […]
