The project provides the benefiting authorities with useful tools and knowledge suitable for use in the protection of the Tonle Sap Lake. It is the largest freshwater lake in Southeast Asia and an important component in the Mekong water system, which includes six countries.

The area is globally unique and thought to be a critical component of the bio-diversity and inland fishery of the entire Mekong Basin. Productivity of the lake is threatened by a variety of changes in its catchment and in the upstream of the Mekong Basin. The project activities in Cambodia include field measurements, mathematical modelling, socio-economic analysis and preparation of management tools, as well as capacity building through training

The work is undertaken by two main organisations: Finnish Environment Institute (SYKE), lead consultant, and Environmental Impact Assessment Centre of Finland Ltd (EIA Ltd).
