Peru's meteorological office Senamhi has projected that rainwater in the Rimac river water basin will decrease 10% from normal levels in the next 15 years due to climate change.
The decrease will affect the water supply for the Lima metropolitan region. Supply for the current population would not be an issue, but there could be a problem in meeting demand from a growing population, according to Senamhi's director of applied hydrology Oscar Felipe Obando, Bnamericas.com reported
The Rimac, Lurin and Chillon rivers are all vulnerable to lower flows due to climate change, according to studies performed in 2008.
In order to confront the problem, Obando recommends more efficient domestic and agricultural use of water, better management of the basin and improving storage systems. In addition, he recommended creating river defense and early alert systems.
The new study was based on rainfall over the last four decades in the zones with the highest levels of precipitation. Senamhi projects that between 2025 and 2035, changes in rainfall will be significant.
