Key City Development Issues

The Tonle Sap basin is home to about a third of Cambodia’s population. Nearly half of the population depends on the lake’s marine resources for their livelihoods. Cambodia’s urban population growth rate of about 4% translates into significant growth in the basin’s towns. The basin’s urban areas are located along rivers that flow into the lake, and most are flooded during the wet season. This means that urban development must be balanced with environmental measures to ensure that urban waste and pollution do not adversely impact the lake’s highly diverse ecosystem. The basin’s urban areas are highly sensitive to climate change, particularly given the lake’s unique hydrology.

Details of Cooperation

CDIA-supported activities included: (i) assistance to the municipalities in undertaking a rapid assessment to produce a medium term prioritized Urban Environmental Infrastructure Program; (ii) conduct of a pre-feasibility study (PFS) for water supply, wastewater and solid waste management infrastructure enhancement in Battambang, Steung Sen, Serei Saophoan, Kampong Chhnang and Pursat; and (iii) preparation of preliminary engineering designs for priority subprojects.

Expected Development Outcomes

Selected provincial towns will benefit from improved operation and management of sustainable water supply, wastewater and solid waste management infrastructure. Increase in wastewater and solid waste service coverage will benefit all residents in these provincial towns, particularly the poor population. Health risks of the residents in the selected towns will decrease from improvement in sanitation and solid waste management service provision.
