Abstract

Over time, the development of human settlements and activities has led to an increasing demand for natural resources, including ecosystem services, which subsequently drives changes in land use. As the process of land allocation establishes a link between the natural environment and human resources, the competition among conflicting land uses becomes significantly important in this context. Various tools are employed to address conflicts among land uses and simulate changes in land use. The CLUMONDO model is one such tool that employs various ecosystem services in the allocation and transformation of land uses, allowing for the simulation of land use changes and land cover. In this research, the CLUMONDO model was utilized to predict the extent of changes in demand for major land uses within the Qareh-Sou watershed over a 10-year period (2020-2030). Variables such as slope, aspect, elevation, the number of neighboring urban cells in a 7x7 grid., temperature, precipitation, distance from rivers, distance from urban areas, and distance from roads were incorporated into the model. An optimization approach was implemented to simultaneously enhance carbon sequestration capacity and designate additional residential areas in a specific scenario. The analysis of results was conducted using Idrisi Terrset and ArcGIS software. The findings indicated that over the next 10 years (2020-2030), land use changes for constructed areas and dense forests followed an increasing trend, while semi-dense forests and agricultural lands experienced a decrease due to their conversion into other land uses. This transformation was aimed at enhancing ecosystem services. This study showcases the possibility of harmonizing diverse, and at times conflicting, services in a way that also addresses human needs
