Abstract
Riparian forest (RF) distributes along riverbanks, considered part of the river-floodplain system, provides longitudinal, lateral and vertical connectivity, as well as numerous ecological functions and ecosystem services (ES). In Yasothorn, many communities sustain their livelihoods through agriculture, freshwater fishing, and benefits derived from ES. This study aims to identify the structure and dynamics of RF, ES benefits to agrarian communities, and monitor changes using two main methods: (1) classifying landscape structures, detecting FPD extents, and riparian coverage through remote sensing, and (2) conducting field observation. The results indicate that RF predominantly located within an extensive floodplain ranging from 3.00-8.00 kilometers. The expansion and contraction of RF coverage are directly correlated with the occurrence of FPD. Ecosystem services from RF are essential for food security, the continuation of livelihoods, and household economy. The Loss of RF is primarily caused by land cover change for farmlands, reservoirs, and urban development, as well as FPD alteration due to dams and roads. These changes have significantly impacted the availability of natural foods sources and benefits derived from natural capital.
