On a global scale, watersheds are currently severely disrupted by climate change and human disturbances. As a representative of the capacity of a watershed to absorb and recover from disturbances, watershed resilience and related transitions in the watershed system has become a vital issue in the maintenance and management of watersheds. In order to understand watershed resilience to change, numerous studies have attempted to improve knowledge about the relationship between natural variables, drivers of change, ecosystem responses, and feedback in a watershed system or its subwatershed. The present study is planned with the aim of evaluating and ranking the watershed resilience index by considering four key dimensions: ecological (8 criteria), social (13 criteria), economic (8 criteria) and infrastructure (13 criteria). For this purpose, first the dimensions and criteria of each dimension were identified taking into account the prevailing conditions in the Shazand area, then information and data on climate, hydrological, demographic, economic and infrastructure and land use were obtained from relevant authorities. Then the mentioned criteria were standardized and the weight according to their importance was calculated based on BWM method and the data obtained from this stage were performed using TOPSIS technique to rank the resilience of the watershed for different subwatershed in Shazand watershed. Finally, a watershed resilience index map was prepared and presented. According to the results of natural environment criteria (ecological dimension), (education of local people (social dimension), livelihood diversity (economic dimension) and access to medical centers (infrastructure dimension) were the most important resilience criteria and among the studied dimensions ecological dimension according to the comprehensive map of watershed resilience index, sub-basin 1 in Shazand basin is the most resilient sub-basin of the study area. |
