摘要

Agriculture productivity is regularly affected by floods and droughts, and the severity is likely to increase in the future. Even ifsignificant efforts are spent on water development projects, ineffective project planning often means that they continue tooccur or are only partly mitigated, for example, in the Mun River Basin, Thailand, where 1,000 s of water projects have beenimplemented. Despite this, the basin regularly experiences floods and droughts. In this study, an analysis of the adverseimpacts of basin-scale floods and droughts on rice cultivation in the Mun River Basin is conducted, and an estimation of thecoping capacity of existing measures. The results demonstrate that while the total storage capacity of in-situ and ongoing projectswould be sufficient to tackle both hazards, it can only be achieved if the projects are effectively utilised. Based on this,proposed solutions for the region include small farm ponds, a subsurface floodwater harvesting system, and oxbow lake reconnections.The suggested measures are practicable, economical, environmentally low-impact, and their implementation (ifexecuted with appropriate care) would reduce flood and drought problems in the basin. Notably, the measures and calculationmethods proposed for this basin can also be applied to other crops and regions.
