After  more  than  twenty  years  of  war  and  instability,  Cambodia  has  entered  a reconstruction phase: physical reconstruction of infrastructures, reconstruction of government mechanisms for its roles of popular service and regulation, and above all reconstruction and modernisation of its institutions. Combining reparation of dikes, transfer of works management to users, improvement of land tenure security and support for the economic development of farms, the Prey Nup polder rehabilitation project is part of this movement. The first experiment in turning over management of an infrastructure to a farmers’ organisation in Cambodia, the Prey Nup project ended in 2008.


The Prey Nup polders cover a territory of 10,500 ha of rice paddies. The project made it possible to grow crops again on 3,000 ha and improve yields on all plots thanks to better water control and agronomic action research. Paddy production in the zone has grown from less than 12,000 tons per year to between 25 and 30 thousand tonnes per year.


A users’ organisation (the Polder Users’ Community - PUC) was set up. It has 15,000 members and manages an annual budget of approximately US$100,000 in membership dues paid by the users. It notably manages water in the irrigation scheme and maintains the separating dikes, canals and sluices. A managerial responsibility-sharing agreement was signed in 2008 with the state who keeps responsibility for maintaining the primary dike (the dike that protects against sea water intrusion).


Simultaneously, agronomic support was provided, both regarding rice and crop diversification (market gardening, fresh corn sold in Sihanoukville, etc.). In this way, the project also made it possible to record the 24,000 agricultural plots in the polders and facilitated the establishment of microcredit services in the district.
