Fishing (IMAGE) NASA/Goddard Space Flight Center Caption This is a person fishing at sunset on Tonlé Sap Lake, near Akal village in Cambodia. Tonlé Sap, which feeds into the Mekong River, is an important food and economic resource for surrounding populations but is threatened by overpopulation, overfishing, dam development and more. NASA and Conservation International are partnering to map ecosystems connected to and including Mekong River to develop tools for evaluating the impacts of such threats as well as potential interventions on the entire Mekong Basin.
