This report is based on key informant interviews conducted in 6 of the 12 villages in the Tonle Sap Lake Region where the WorldFish-led CGIAR Research Program on Aquatic Agricultural Systems (AAS) proposes to work with local communities and other stakeholders to address natural resource management and related livelihood challenges. The socioeconomic setting of the Tonle Sap Lake is characterized by a rapidly growing population, high poverty levels and deep dependence on natural resources. The key informant interviews conducted by the International Water Management Institute are intended to record both significant differences and similarities among the villages, especially with respect to the types of institutions linked to fisheries, agriculture and water management, and thereby to help identify both village-specific and cross-cutting constraints and opportunities with respect to the identification and design of interventions.
