The FAO Project "Participatory Natural Resource Management in the Tonle Sap Region" is funded by the Belgian government and implemented through the Food and Agriculture Organisation of the United Nations (FAO).

The project works in direct collaboration with the provincial departments of forestry, fisheries, agronomy, rural development and environment within the province of Siem Reap.

The primary objective of the project is to facilitate responsible, productive and sustainable management of locally accessible natural resources by communities to meet local needs and to stimulate local development. An important part of this process is environment education, and to this end, the project founded the GECKO environmental education center in 1999 in collaboration with the provincial environment department.
