Préface
The present study deals with the land use land cover (LULC) change detection analysis using remote sensing and GIS in Chaksu Block of Jaipur district. A major flood in year 1981 in Jaipur district resulted in huge erosion of the top fertile soil, leaving the land unproductive for agriculture production. In order to manage the effects of disaster, restoration of the degraded land was undertaken by the local natives with the help of the forest department. This study focuses on the evaluation of the changes in LULC of the study area before and after restoration with the help of remote sensing and GIS technology. The most fundamental characteristic of remote sensing technology is that it provides comprehensive information on land at regular intervals and on large spatial coverage. The LULC of the study area encloses mapping of kharif season satellite data of September month. The methodology adopted includes visual interpretation of LANDSAT images to generate thematic maps. These maps were obtained by using LANDSAT images, collateral data like SOI toposheets, rainfall data and relevant published literature. The area was categorised into seven LULC classes namely agricultural land, built-up land, gullied land, fallow land, scrub land, water bodies and river course. Among all the LULC categories, agricultural land constitutes 29% of the total study area. Chapter 1 deals with the introduction, objectives and scope of the study. The literature related to the study is discussed in the Chapter 2.The methodology and database to fulfil the objectives is presented in the Chapter 3. The land use categories of the study area along with their estimated area for 5 different years are briefed in Chapter 4.Chapter 5 concludes the findings of the study and future recommendations were listed. The references related to the study cited in the chapters are listed at the end of the thesis in Chapter 6. The LULC classes reviews the environmental health of the area which helps planners and decision makers to make optimal use of the land to enhance its prosperity and productivity. Monitoring the pattern of LULC changes forms a basis for conserving, managing and planning land resources as these kind of studies have plausible effects on local, social and environmental conditions.
