Many of the poor households in the provinces surrounding the Tonle Sap Lake would migrate seasonally to the lake and upland forests to meet their food shortfalls and supplement their livelihood in the villages. This exacerbated the severe threats to the lake’s ecosystem, which included overexploitation of fisheries and wildlife resources, land clearance of the flooded forest, pollution, natural resource degradation, and more.
To help reduce the need for the poor to encroach into the lake, which is central to sustaining the Tonle Sap Biosphere Reserve (TSBR), the Asian Development Bank (ADB) approved in December 2007 a $10 million loan and a $9.9 grant for the Tonle Sap Lowlands Rural Development Project. The project focused on improving the livelihood and income opportunities in 40 selected communes of 3 lowland provinces in the Tonle Sap basin. It had 3 planned key outputs (i) improved rural infrastructure, (ii) improved rural livelihoods and employment options, and (iii) strengthened project management. Output 1 rural infrastructure improvements were to be delivered in 3 sub-output areas: social infrastructure, agricultural water management, and rural roads.
At project completion, 160 subprojects supported the construction or rehabilitation of commune council buildings, village or commune roads, schools, wells, latrines, conservation ponds, and riverbank protection structures; 58 subprojects rehabilitated or upgraded irrigation canals, embankments, and other small-scale irrigation infrastructure, increasing the total irrigated area to 13,376 hectares or 139% of the target; and 54 subprojects rehabilitated or constructed a total of 205.91 kilometers of rural roads or 90% of the target. 7 major subprojects supported the dissemination of modern farming practices and agricultural technologies.
Community participation in identifying, prioritizing, and implementing the subprojects was ensured through the community-driven Commune Investment Plan process and the formation of several community organizations, including farmer water user groups, road operation and maintenance groups, savings groups, agricultural cooperatives, and on-farm and off-farm business groups. Special attention to promoting women’s participation and access to project benefits resulted in women comprising 43% of the 16,112-total membership in community organizations and 60% of the 42,246 beneficiaries of agricultural training and extension.
Delivery of almost all the planned outputs allowed the project to achieve its overall aim to increase livelihood and income opportunities through improved infrastructure and services. By project completion: cropping intensity had risen, with farmers growing 2–3 crops per year; paddy rice production increased by 23.8% during the wet season and 99.6% during the dry season. 439 new enterprises, including 397 agri-businesses composed and run mostly by women, provided additional incomes to poor households. Overall, the project helped reduce poverty incidence in the participating communes from an average of 46% in 2007 to 25% in 2017 and enhance the connectivity, productivity, and food security of the poor in turn reducing their need to enter the TSBR buffer zone to meet livelihood and food shortfalls.
ADB’s Southeast Asia Department rated the project successful. The Ministry of Water Resources and Meteorology (MOWRAM) was the executing agency. MOWRAM, the Ministry of Rural Development, Ministry of Agriculture, Forestry, and Fisheries, and provincial local administration units implemented the project.
