Fixing the Flawed Colorado River Compact
The 1922 Colorado River Compact ignored available science and overallocated the river’s water, a decision whose effects reverberate today. Now there’s an opportunity to get things right.
Groundwater Pumping Is Causing Mexico City to Sink
Researchers say knowing how much water is being extracted is crucial for addressing infrastructure and water supply crises in the capital.
Greening of Loess Plateau Increases Water Yield
Vegetation restoration over the Chinese Loess Plateau can enhance atmospheric moisture convergence, increasing the precipitation enough to compensate for the vegetation water consumption.
مراقبة تراكم الملوثات من المعادن الثقيلة في دلتا النيل
تُظهر نتائج تحاليل العينات أن إعادة استخدام مياه الصرف بدون معالجة والتوسع في إنشاء السدود يسبب زيادة تركيز المعادن الثقيلة الملوثة في دلتا النيل مما يهدد بشدة سلامة النظام البيئي والصحي والإنتاج الزراعي في مصر.
Redefining “Glacial Pace”
As Earth’s climate warms, glaciers and ice sheets are retreating, cracking, and adding to sea level rise at record speeds.
GPS Observations Sense Groundwater Change in Australia
By exploiting the fact that changes in groundwater cause deformations of the Earth’s surface, GPS receivers are used to detect groundwater changes related to extreme events and to seasonal oscillations.
Ten Rivers Facing Pollution, Development, and Climate Change—And Policies That Can Help
An annual report highlights 10 waterways that have arrived at forks: where public support could determine whether they receive protection.
Urban Water Conservation Success in the Colorado River Basin
In the past few decades, cities in Arizona, Colorado, and Nevada have vastly increased their water use efficiency. They’ve also learned lessons that can inform other cities’ efforts.
Tracking Heavy Metal Accumulation in the Nile Delta
Sediment measurements show that flow alterations and discharges are driving increasing concentrations of multiple heavy metals in the Nile Delta, threatening ecosystems, agriculture, and human health.
