The IWHF employs global expert opinions and the Analytic  Hierarchy Process (AHP) as decision management tools to define criteria for weighting  key watershed health attributes, prioritizing ecological factors (48.8%), followed by  economic (21.9%), socio-cultural (16.9%), and policy (12.4%) considerations. The  IWHF was applied to the Nan River Basin (NRB) in Northern Thailand to assess 17  sub-basins. Hydrological modeling using the Soil and Water Assessment Tool (SWAT)  and geospatial analysis (GIS) identified well-functioning sub-basins and highlighted  areas requiring improvements in ecological conditions, socio-cultural engagement,  economic stability, and policy frameworks. A vulnerability analysis, integrating  CMIP6-GCM climate projections under SSP2-4.5 and SSP5-8.5, Dyna-CLUE land-use  projections, water use scenarios, and GIS analysis, revealed increasing vulnerability  over time. While most sub-basins remained stable in the Near Future, several  transitioned to vulnerable states in the Mid and Far Future due to intensifying stressors.  Sub-basins in the Lower NRB, dominated by agriculture and expanding urban areas,  were the most susceptible due to rising impervious surfaces, shifting water use patterns,  and climate change impacts. To guide conservation and restoration, sub-basins were  classified into four management groups: Protect, Protection Priority, Restoration  Priority, and Restore. Resilient sub-basins were designated for conservation, while less  resilient ones required immediate intervention to prevent long-term degradation. The  study recommends adopting climate-resilient agriculture, improving water  conservation in agriculture and industry, and strengthening governance mechanisms.  Integrating digital monitoring tools and promoting research innovation will be crucial  for sustaining watershed resilience through adaptive management. These strategies  provide valuable insights for policymakers and stakeholders to support the long-term  sustainability of the NRB and other vulnerable watersheds.  0aWatershedszThailandzNan River BasinxManagement 0aClimatic changeszThailandzNan River Basin 0aLand usezThailandzNan River Basin1 aShrestha, Sangam,eChairperson0 aThammarat Koottatep,eExamination Committee1 aShanmugam, Mohana Sundaram,eExamination Committee0 aNatthachet Tangdamrongsub,eExamination Committee1 aKhadka, Dibesh,eExamination Committee2 aUniversity of Science and Technology of Southern Philippines {u2013} Cagayan de Oro (USTP-CDO),eScholarship Donor2 aAsian Institute of Technology.tDissertation :vno.WM-25-03403Full-Textuhttp://203.159.5.9/ait-thesis/detail.php?q=B22136
