Climate change is threatening an enormous reservoir of pure water with extinction
Climate change is causing the glaciers in Bolivia to accelerate melt, and there are concerns that water resources may run dry in the future. One study found a 56% glacier loss in the past 50 years. This project will work to develop monitoring techniques for securing sustainable water resources. Efforts will focus on projecting the amount of glacier melting that will occur in the future and estimating the changes in water demand accompanying urban population growth. The project will also consider reservoir sediment management and water environment, as well as the water quality of alternative water sources, and will include modeling to support water resource policy from a multifaceted perspective.
Water resources viewed from a multifaceted perspective to develop new management models
Satellite data will be used to analyze changes in glacier and snow area in the Andes highlands. The project is also working on projecting the accumulation of sediment in reservoirs, assessing water quality, examining changes in demand for water in the capital La Paz and the neighboring city of El Alto, and conducting water quality surveys of alternative water sources. The results of these studies will be integrated to reveal the impact of melt water from glaciers on water resources, and used in the creation of water resource management models for La Paz and El Alto.
