I think this article may help answer this question. The article is entitled “Of Fish, Monsoons and the Future: A Push to Save Cambodia’s Tonle Sap Lake” by Chris Berdik over at the New York Times.
It’s a great article looking at the role of human activity on nature. As is stated towards the end,”Tonle Sap project is designed to capture those interactions and look for their consequences, often unintended”.
Worth a look!
