Cambodia-Australia Agricultural Value Chain Program

Water management has always been important to Cambodian people for agricultural production and supporting livelihoods. The irrigation system in Angkor over a thousand years ago was one of the largest in the world. There are now over 2,500 irrigation schemes in Cambodia. Most were constructed during the Khmer Rouge period in the late 1970s and many are not fully operational, requiring rehabilitation and in some cases decommissioning.

This series of Short Technical Briefs draws from the lessons learned under CAVAC to raise awareness of steps for establishing sustainable irrigation in Cambodia. New briefs will be uploaded periodically.

Managing Water Resources
River basin management plans: purpose, functions, and types
River basin management plans: purpose, functions, and types

A river basin management plan is widely considered an important tool for supporting the sustainable development of water resources. Cambodia’s Water Law mandates the Ministry of Water Resources and Meteorology to oversee river basin planning in collaboration with all concerned ministries.

Using water simulation models to support sustainable water resources management
Using water simulation models to support sustainable water resources management

Water simulation models help river basin managers and river water users to confidently plan, develop, and sustainably manage water resources. This STB outlines the main types of water simulations models used for water resources management and their value for understanding the status of water in each river basin to ensure sustainable infrastructure and economic development.

Securing water to support Sustainable Irrigation
Securing water to support Sustainable Irrigation

To manage water resources effectively it is important to understand how much water is available to support irrigation, energy production, urban and rural water supply, industry, the natural environment, etc. Changing climate and development pressures (e.g. irrigation expansion) will continually impact the availability of water.

Rehabilitating irrigation schemes
Achieving sustainable irrigation: overview of the process
Achieving sustainable irrigation: overview of the process

One of the first steps is to determine the selection criteria for identifying schemes to be rehabilitated or constructed. These criteria are used to inform an initial list of project areas and potential irrigation schemes to be considered. CAVAC developed its selection criteria based on the lessons learned during the implementation of its first phase (2010-2015).
