The expanding and contracting of this seasonal flood pulse inspires the lake’s comparison to the “beating heart” of Cambodia, and fuels extreme productivity that supports a fishery of 300,000 tons a year. The Tonle Sap was a central focus of the recent International Symposium on Flood-Pulse Ecosystems in Siem Reap, Cambodia. The conference described changes underway in many aspects of the Tonle Sap, from the food web, to the fish catch, to human activities. Such changes underscore the important decisions facing Cambodia about the future of the lake, and how to address various needs of power generation, food security, and conservation in a sustainable way.
