To better understand energy utilization in irrigated agriculture, Asian Development Bank (ADB) financed a study for Pilot and Demonstration Field-Based Research: Quantifying Water and Energy Links in Irrigation for Improved Resource Utilization in Viet Nam.
The study was conducted by the International Food Policy Research Institute with support from a Viet Nam-based consultant within a suitable area identified in the central highlands of Viet Nam.
The study is linked to an ADB-financed project preparation technical assistance for Water Efficiency Improvement in Drought Affected Provinces. The project is under implementation in Viet Nam and aims to provide improved water saving practices and technologies for high value crop cultivation in the
The following are the recommendations of this report:
- Raise awareness on water (and fertilizer) requirements for optimal yields (including groundwater governance mechanisms).
- Collect data on high-efficiency irrigation system (HEIS) adoption levels (to be carried out by provincial government agencies).
- Assess the potential impact of a water service charge on HEIS adoption.
- Conduct additional studies of HEIS impacts on all energy components.
- Highlight key energy savings, e.g., those from reduced fertilizer application (which also reduces water pollution levels, labor cost, etc.) in promoting adoption of HEIS.
- Assess the potential of enhanced groundwater governance system to reduce overwatering and induce water savings.
