The previous reports have outlined the current scientific knowledge of climate change and its impacts on tropical Andean glaciers and hydrology (Part I: The scientific basis) and the ongoing research and monitoring activities by the various institutions currently active in the region (Part II: Climate and Glacier Monitoring). It is clear that some practical measures to adapt and prepare for future changes in runoff behavior need to be implemented without delay (e.g. conservation, shift to less water-intensive agriculture, creation of water reservoirs, etc., see Vergara, 2005), but at the same time significant progress needs to be made on the scientific front. This third and final report (Part III: Future Recommendations) suggests a number of research strategies that would allow answering some of the most urgent scientific questions related to Andean climate change.
