Background
The Ministry of Public Works and Transport administers transport and public-works infrastructure that intersects with river and basin systems used for navigation, flood control, and water-dependent infrastructure in Cambodia. Basin-level planning coordinates infrastructure investments, flood management operations, irrigation systems, and water allocation among national and subnational authorities.
Cambodia’s primary river systems include reaches of the Mekong River and the Tonle Sap basin, which require coordinated planning across agencies and sectors to manage seasonal floods, irrigation and fisheries impacts. Climate resilience grants commonly fund institutional capacity building, strategic planning, and monitoring systems to support basin-scale water governance.
Key Developments
On 21 May 2026, Secretary of State Kuoch Bunlat of the Ministry of Public Works and Transport joined the official launch of the Australia–Cambodia Partnership for Climate Resilience (ACP4Climate) under a bilateral cooperation framework. The ACP4Climate program aims to strengthen institutional capacity, improve planning and coordination mechanisms for diverse water resources, and promote evidence-based, environmentally sustainable water governance.
The MPWT statement listed three current Australia-supported water-sector initiatives in Cambodia: (1) an investment appraisal project for water infrastructure conducted through the Australian Water Partnership (AWP); (2) development of a fisheries-agriculture-water-rural strategic framework for 2027–2031 under the Cambodia–Australia Partnership for Resilient Economic Development (CAPRED); and (3) the ACP4Climate programme, which received grant funding for its first implementation phase covering 2026–2030.
Institutional Role
ACP4Climate is framed as an inter-agency capacity and planning intervention rather than a single infrastructure project. The programme is intended to support basin-level planning efforts that involve multiple ministries and technical working groups responsible for water, fisheries, agriculture and rural development.
Operational Implications
For public agencies and technical working groups, ACP4Climate signals targeted support for planning processes, evidence-based decision-making, and coordination mechanisms across the Upper and Lower Mekong reaches and the Tonle Sap basin. The 2026–2030 phase-one funding window defines an initial implementation period for capacity-building, planning tools, and pilot coordination arrangements.
