Hydropower lost in one area is often replaced by fossil fuel power produced elsewhere—and renewable energy sources may struggle to meet electricity demands caused by more frequent dry spells.
Years of drought and climate change are causing water resources to dwindle in the Colorado River Basin. But farmers and scientists are collaborating to learn how to grow crops with less water.
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.
Warming temperatures and less rain are causing flash droughts to develop more quickly and strike more often.
Some southern beeches in the Andes have plumbed deeper for moisture as the surface has dried up. But doing so may deplete resources and undermine the trees’ future health.
The Bronze Age civilization adapted to changes in climate but suffered during a prolonged crisis.
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.
As Colorado River Basin states prove unable to reach a consensus in reducing their water consumption, the U.S. Department of the Interior is investigating an option that defies the Law of the River.
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.
Secas e enchentes alteraram radicalmente a agricultura familiar, mas lideranças femininas estão encontrando soluções para si e suas comunidades.
