چکیده
In light of escalating climate change and its consequences, urban resilience has emerged as one of the most critical approaches to sustainable city management. Zahedan, due to its geographical location and arid to semi-arid climate, faces significant challenges such as rising land surface temperatures, declining soil moisture, intensifying drought conditions, and increased frequency of dust storms. This study aims to assess the impact of green spaces on reducing climate vulnerability and enhancing urban resilience by focusing on two neighborhoods with contrasting conditions: Daneshgah (University) and Shirabad. Landsat satellite imagery was employed to analyze changes in vegetation cover (NDVI) and land surface temperature (LST) over the period 1980–2023. Climatic variables including air temperature, precipitation, humidity, and wind were analyzed using time series analysis and the Mann-Kendall trend test. Additionally, the TOPSIS multi-criteria decision-making model was used to rank neighborhood vulnerability and resilience levels. The results indicate a significant decline in vegetation cover and a concurrent increase in land surface temperature in Zahedan over the past four decades. Drought indices further reveal that decreased precipitation and humidity are key drivers of these trends. The Daneshgah neighborhood, characterized by more extensive vegetation, demonstrates higher climate resilience compared to Shirabad. Vegetation in this area contributes to urban resilience by absorbing carbon dioxide, producing oxygen, lowering ambient temperatures, and enhancing soil water retention thereby improving air quality and mitigating urban heat island effects. In contrast, Shirabad’s dense construction, lack of adequate infrastructure, and scarcity of green space result in higher climate vulnerability. The findings underscore the importance of sustainable urban green space management such as selecting drought-resistant plant species, implementing smart irrigation systems, and developing green belts in effectively enhancing urban climate resilience.
