Smaller Settlements are important for sustainable housing; however, a large proportion of urban area is covered by squatter settlements and slums in Indian cities with poor housing facilities. Growth of such slum clusters is a major problem which is further exacerbated by increasing urban development and deficit of affordable housing. There are many challenges in the task of making cities free of slums and improve the situation in existing slums. Spatial mapping of such areas is an effective tool for the improvement of slums. In this study, an attempt has been made to study the slum settlements in Dehradun city with an objective to provide useful information on sustainable housing as well as help planners make appropriate interventions using remote sensing and GIS. The purpose of this study is to locate the livelihood problems for promotion of sustainable life in slums, households having roof material other than concrete, not having facility of drinking water; drainage and latrine are treated as slums as well as contiguous area with 20-25 households.
