The natural water system in the Central Andes suffers from glacial retreat and other climate change impacts. First evidences are found on an actual and future decrease in water availability and increment of river flow variability in glaciated basins such as Rio Santo (Cordillera Blanca, Ancash) and Rio Vilcanota (Cordillera Vilcanota, Cusco). Water supply is at risk, while the population and economy in Ancash and Cusco continue to rise. Agriculture expands, irrigation becomes more intense and energetic demand increases. The actual project seeks to quantify water supply and demand through an interdisciplinary water balance by identifying and connecting determinant variables.
Prepare a water balance of the basins in the Central Andes. Develop future scenarios of water supply and demand. Formulate climate change adaptation strategies to reduce the risk of hydric stress.
