Climate Risk Management and Rehabilitation of Small- and Medium-scale Irrigation

The project preparatory technical assistance (PPTA) will conduct technical, economic, financial and social due diligence to prepare the Climate Risk Management and Rehabilitation of Small- and Medium-scale Irrigation Schemes in Tonle Sap Basin, a project under the Strategic Program for Climate Resilience (SPCR) for Cambodia. SPCR Cambodia forms part of the global Pilot Program for Climate Resilience (PPCR) supported by the Climate Investment Fund (CIF). A program for rehabilitation of small- and medium-scale irrigation schemes in Tonle Sap Basin has already been initiated under ADB financed Water Resources Management Sector Development Program (WRMSDP, Loan no. 2672-CAM)2, and the PPCR project will provide for (i) additional support to enhance the climate resilience of the rehabilitated irrigation facilities and improved agricultural activities; and (ii) capacity strengthening for mainstreaming resilience to development planning in water resources and agriculture sectors. The PPTA will be administered under TA 4848-CAM: Water Resources (Sector) Project. The irrigation engineer, in coordination with hydrologists and agricultural specialists, will: (i) assist the climate change specialists in the preparation of the climate change impact, vulnerability and adaptation assessment; (ii) develop improved climate resilient design criteria for irrigation systems; (iii) develop construction and maintenance cost estimates for subprojects selected for upgrading; (iv) assist project economist (in collaboration with the irrigation engineer (national)) prepare detailed cost estimates; and (v) provide support to the loan-financed design engineers to improve irrigation designs with particular emphasis on climate resilience of the proposed subprojects under WRMSDP.
