Land and water resources are the decisive factors for the socioeconomic development of any country. Since now land is becoming a scare resource because of immense agricultural and demographic pressure. Hence, information on land use / land cover and possibilities of their optimal use is vital for the selection, planning and implementation of land use scheme to meet the increasing demands for basic human needs and welfare. The recent remote sensing and GIS techniques can be useful measure to generate data and information for sustainable development. In this paper an attempt has been made to study the changes in land use and land cover of Western part of Solan district. The study was carried out using Remote Sensing and GIS approach using Landsat imageries of 2000 and 2010. GIS software is used to prepare the thematic maps. The result of the work shows a rapid growth in built-up area between 2000 and 2010. INTRODUCTION: All Human activities are based on natural resources and land is the most important resource. Rapid Growth of population is increasing more pressure on land resource. Human activities are mounting the demand on the existing land resources to fulfil their basic needs based on agriculture, forest, pasture, urban and industrial land use. Information on the degree and type of changes in the land resources is essential for proper planning, management and to regularize the utilization of such resources (Gautam N.C. & Narayanan, E.R., 1983).India is also facing a problem of natural resource scarcity, especially that of water in view of population growth and economic development (Yadav et al., 2013). As a result land use / land cover (LULC) changes have become a central focus point of interest within the environment scientist community (Meyer et al., 1996). Consequently, evaluating and understanding of the extent and spatial distribution of LULC is a vital significant to the study of environmental changes at various level (Ojima et al., 1994). Moreover, scientific investigation of these types of issues serves as a valuable tool to increase efficiency of LULC and also to decrease the negative societal and environmental impacts associated with the land use / land cover. Present geo-spatial technologies such as geographical information system (GIS), remote sensing and photogrammetry have capability to analyse the real world problems and to give effective spatial solutions. The repetitive nature of spatial data has proved to be very useful in mapping land use / land cover pattern, trends and change within the time. Thus, geo-spatial techniques are capable to detect changes over the period within the specific region with low cost, less time and better accuracy. Different spatial layer can be produced from satellite data to analyse in geo-spatial environment such as drainage, lithology, land use / land cover, geomorphological conditions and degraded landforms. These data sets are the fundamental requirement of the geographical information system (GIS) that provides an excellent mean of spatial database analysis and interpretation (KotokyP., et al., 2012). Quantification of land use / land cover changes is possible through GIS techniques on different scales and resolutions (Sharma et al., 2001). Studies based on geo-spatial techniques are helpful in understanding the dynamics of human activities in space and time. During the period of 70s and 80s satellite data were used in simple interpretation or as a reference map (Merified P.M., & Lamar D.L., (1975) Rib H.T., & Liang T., (1978) but at present with the advancement in tools,spatial analyses are possible. Remote sensing and GIS techniques have been applied by various researchers of different disciplines such as forest, agriculture, planning, disaster management and natural resources etc. (CracknellA.P., (2000); SabinsF.F., (1997); Dixon,T.H., (1995). Therefore, accurate and updated spatial land cover information is necessary to understand and asses the environmental consequences of changes over the time period (Giri et al., 2005). The application of GIS and RS is rapidly expanding worldwide for planning, management and solution of real world problems. Few examples of on-going / completed Geospatial Projects of Government of India under NNRMS (National Natural Resource Management System) are Forecasting Agricultural output using Space, Agro meteorologyand Land based observations (FASAL); National Agricultural Drought Assessment and Monitoring System; National Wastelands Monitoring; Potential Fishing Zone; Ground Water Prospects Mapping; Accelerated Irrigation Benefit Program; Watershed monitoring and development; Remote sensing based Integrated Mission for Sustainable Development; Water Resources Information System; Biodiversity Characterization; National Wetlands Inventory and Assessment; Snow and Glaciers; Coastal Zone Studies; National Urban Information System; Natural Resources Census and Space Based Information System for Decentralized Planning (SIS-DP). The present study has been taken up in order to understand the changes that have taken place in land use/land cover in western parts of Solan district of Himachal Pradesh. This area has become the industrial hub of Himachal Pradesh in recent times. It is believed that this rapid urbanization and urban sprawl might have influenced on the land use/land cover patterns resulting in a possible impact on the environment. This work is taken up to better understand this aspect. OBJECTIVE The aim of this study is to produce a land use/land cover map of western part of Solan district of Himachal Pradesh in order to detect the changes that have taken place over a given period using change detection method and to determine the location and magnitude of land use / land cover change. DATA AND METHODOLOGY In the present study, for evaluating the temporal changes in the land use and land cover, Landsat ETM+ satellite data has
