Assessment of the Impacts of Climate Change on Mountain Hydrology : Development of a Methodology through a case study in the Andes of Peru

This analytical report presents a summary of methodological tools for the assessment of climate impacts on surface hydrology in the Peruvian Andes. The importance of analyzing the potential climate impacts on hydrology in Peru arises in part from concerns about the retreat of tropical glaciers, the drying of unique Andean wetland ecosystems, as well as increased weather variability and weather extremes, all of which will affect water regulation.

The study is intended to inform plans for energy development in Peru and enable the consideration of the consequences of climate change for such development. It provides some insights into how hydrology may behave under future climate scenarios in Peru.
