Physical features of unplanned settlements in Herat City, Afghanistan

Abstract

Abstract The increase in urban population growth has contributed to the expansion of unplanned settlements, especially in developing countries. Triggered by the lack of government oversight, the expansion of these settlements is characterized by unique economic, social, physical, and functional attributes. This study aims at exploring the physical features of unplanned settlements in District 4th of Herat city, western Afghanistan. Employing a mixed-research method, we integrated spatial analysis using Geographic Information Systems (GIS) into detailed field observations to get a better understanding of the characteristics of the formation of these informal settlements. Our findings shed light on a number of key physical features including irregular street layouts, inadequate drainage systems, and substandard construction materials, irregular buildings in term of layout, number of floors, and building density. The features of unplanned urban morphology contribute to socio-economic loss and environmental degradation due to the absence of critical infrastructures including water infrastructures and the presence of unplanned streets in under-resourced unplanned settlements. In fact, the absence of government’s efforts in monitoring the development of unplanned settlements hinders the provision of essential services and infrastructures in the informal settlement communities. Our assertion is that the findings of this research will help policy makers in Afghanistan to reconsider their policies and decisions on urban development and growth, particularly in the poorer and under-served unplanned settlements in major cities in Afghanistan.
