Leonardo Sáenz (lsaenz@conservation.org) is Conservation International’s director of eco-hydrology. He would like to dedicate this blog to the memory of Dr. Fred Scatena, who helped us advance our understanding of these beautiful ecosystems and of their important services to people. He is also grateful to the Challenge Program on Water and Food (CPWF) and its focal project for the Andes, which has helped to improve understanding of the most pressing water challenges in the region and of the role of benefit-sharing mechanisms, including the public and private sectors, in order to tackle them more effectively. - See more: Cloud forest coverage critical to keep tropical dams running.
