| Abstract | Ecosystem-based solutions in addressing issues related to soil and water conservation are relatively new to the Southeast Asian Region. This study focuses on assessing the impacts of Ecosystem-Based Adaptation (EbA) on sediments in a small watershed in Mukdahan Province of Northeast Thailand. The study watershed is currently predominated by forests. The purpose of this study is to demonstrate the usefulness of EbAs in degraded watershed conditions to control sediment loading in the downstream. Seven watershed degradation scenarios were developed using specific rules and planning.
Simulations were carried out using Soil and Water Assessment Tool (SWAT) to examine the impact of EbAs on sediments. The study results revealed that cassava dominated watershed degradation scenarios yielded highest soil erosion rates in Huai Ta Poe. Individual and combined impacts of EbAs were evaluated. The combined EbA scenario comprising reforestation, grassed waterways and filter strips yielded highest reduction in soil erosion in the downstream. |
