Irrigation and hydropower

open access: yesEos, Transactions American Geophysical Union, 1976
The pairing of irrigation and h y d r o p o w e r in a discussion of progress in the hydrospheric sciences may seem an incongruity. In many ways the use o f water for irrigation or for the generation of electric power is in conflict, the first requiring seasonal use only and the latter a steady supply year around with only daily fluctuations to meet ...

Avoiding ecosystem and social impacts of hydropower, wind, and solar in Southern Africa’s low-carbon electricity system

open access: yesNature Communications
Avoiding the most damaging land use and freshwater impacts of solar PV, wind, and hydropower development while halving carbon emissions by 2040 in the Southern Africa region is not only possible but incurs only modest (3-6%) system cost increases.
