Soil plays a critical role in providing various Ecosystem Services (ESs) that are beneficial to humanity. Services such as clean air, water, and food production are directly or indirectly provided through soils. The soil ecosystem is considered as the most important Carbon (C) sink in terrestrial systems, and human activities, particularly land use, impact ESs and increase carbon emissions into the atmosphere. Mapping ESs and assessing the risks associated with climate-related hydro-meteorological hazards and soil degradation can contribute to making spatial decisions for planning more climate-resilient. Indeed, strategies based on soil ecosystem services provide valuable insight for enhancing the resilience of spatial decision-making in adapting to climate change. The aim of this article is to illuminate the significance of SoES in the spatial planning decision-making for better integration and adaptation into climate change adaptation policies as a decision support tool. In this regard, ESs related to climate change were highlighted and mapped, and their suitability for settlement development decisions and relation with ESs’ integrity were assessed through weighted multi-criteria analysis, while discussing the contributions of this process to climate change adaptation. Incorporating Social-Ecological Systems (SoESs) factors into suitability analysis is crucial for comprehensive urban planning, particularly in the context of climate change adaptation and environmental protection. In this study, two settlement suitability analyses were conducted. The first analysis considered various factors, such as land use, soil classification, DEM (Digital Elevation Model), and slope. The second analysis utilized weighted climate-related SoES indicators, including soil depth, soil carbon sequestration capacity, soil loss, flood risk, temperature, and precipitation. The results revealed that the SoES-based suitability analysis was more stringent in identifying suitable areas for urban development and offered a more holistic perspective for urban planners.
