Abstract: Urbanization dramatically alters landscapes and ecological conditions. This study examines the environmental conditions within Dar es Salaam, Tanzania, using the Settlement Surface Ecological Index (SSEI). The SSEI combines biophysical parameters from satellite imagery to assess ecological health, revealing disparities across diverse urban typologies. This study’s methodology demonstrates advancements in using the Calculate Composite Index tool for streamlined index creation and greater flexibility in urban analysis. Statistical analysis reveals crucial relationships between ecological conditions and variables like tree cover, impervious surfaces, vegetation moisture, and Land Surface Temperature (LST). Multivariate clustering highlights distinct areas of high and Low SSEI, emphasizing disparities in urban ecological health. This study demonstrates how composite indices like the SSEI can inform targeted urban planning, promote green infrastructure, and mitigate the negative impacts of urbanization, ensuring both equitable and sustainable development in the face of climate change.
