Irrigation infrastructure should be built to last. Frequent damage to irrigation facilities caused by flooding and landslides is a big threat to the sustainability of infrastructure improvements. Considering the poor watershed management in the areas surrounding subprojects and incompatible land uses (e.g., hilly land corn farming above the irrigated rice fields), the construction of irrigation infrastructure needs to improve. Preventive and protective measures need to be taken to guard against recurring intense rainfalls and extreme weather events. Such measures could take account of environmental risks and ecological accidents and apply watershed management approaches. This would build long-term climate resilience, supporting the government’s Agriculture Development Strategy to 2025 and Vision 2030.
