Climate change risk and adaptation assessment for irrigation in southern Viet Nam: Water efficiency improvement in drought-affected provinces

This report presents the results and findings of the climate risk and adaptation assessment (CRA) of the Water Efficiency Improvement in Drought-Affected Provinces (WEIDAP) project in Viet Nam. The CRA adopted good practices from the Asian Development Bank (ADB) Climate Risk Management Framework (ADB 2015a, 2016b) and international guidelines (e.g., EUFIWACC 2016), particularly in considering a wide range of possible climate futures and potential risks over the lifetime of the proposed investment. The TA team was thus able to take stock of climate adapation activities that were already part of the project, as well as to refine the team’s recommendations. Those same practices also informed the detailed design of the project and the monitoring of progress in implementing climate adaptation measures.

The report was prepared to capture lessons learned from the CRA for the WEIDAP project and new developments in climate risk assessment that are relevant to ADB operations and future risk assessment projects. These lessons and new developments are highlighted throughout the report with cross-references to other ADB reports or external resources.
