À time series analysis of seasonal NDVI have been used to estimate net primary productivity, phonological characteristic of vegetative surface, length of growing season and dry drown periods (Ramsey ef al., 1995). The study is designed to achieve the objectives to Study the changes in vegetation for selected watershed in a desert districts of Bhilwara, Barmer & Jaisalmer in Rajastan State of India, to identify the changes in density of vegetation, to assess the temporal changes and to assess the impact of the watershed, with an objective to conserve the soil erosion and harvest the rainwater in order to increase the ground water table, to improve the socio economic condition of the people and to stop the migration of the people from the villages in search of livelihood. These activities will have a direct impact on the crop production. The Changes in density of vegetation indicates the quantity of crop production and the growth of vegetation apart from crops and the conservation of land with out scrub/barren land to land with scrub. This gives an picture about the impact of watershed programme in increasing the vegetative cover. The temporal changes help in understanding the changes taken place in the watershed, and facilitate understand the positive as well as negative impacts of any decisions taken in the implementation. The extent and density and type of vegetation for the years, 2000,2004,2005,2007 and 2008, was studied and vegetation growth was analysed using GIS and Digital Image Processing techniques. 1. INTRODUCTION Till the recent past, land was looked in a narrow perspective of being a physical entity in terms of its topography and spatial nature.But the broader, integrative or holistic view, takes into account both, a vertical aspect — from atmospheric climate down to ground water resources, and a horizontal aspect an identifiable repetitive sequence of soil, terrain, hydrological, vegetative and land use elements. Watershed-based development has been the strategy for growth and sustainability of agriculture in the vast semi- arid and dry subhumid regions popularly called rain-fed regions. Watershed Development Projects have been undertaken to enhance agricultural production, conserve natural resources base and ensure rural livelihood since 1980s. Initially soil and water conservation was the primary objective of the program which attracted large public investments in the last 25 years. Subsequently, egalitarian principles of equity and enhancing rural livelihood were given prominence; more recently the principle of sustainable development with emphasis on tenets of development economics like cost of degradation of fragile land and economic ecology like valuation of ecological services have gained emphasis. Large investments have been assigned for watershed based development in the India’s National Five-Year Plans since 1990s and more Investments have been earmarked till 2025. The natural resource data thus generated will be useful to conserve and manage watershed properly to achieve sustainable development particularly, in ecologically fragile areas in order to meet the living standards of the rural communities. The restoration of ecological balance and the productivity of various landbased activities, which can indirectly generate gainful employment to the rural poor, can be achieved through the effective use of this reliable decision support system. This model provides a holistic picture to enable to share the natural resources and protect them for the betterment of the watershed community. This will also help to plan the Infrastructural development needed such as connecting market with local produce. Geo- technical appraisal of all the surface water irrigation projects necessary to avoid unfavorable natural conditions will be easier to develop through participatory method. The Geoinformatics based evaluation of watersheds implemented in the districts of Barmer, Bhilwara and Jaiselmer of Rajastan State, India have generated digital layers of scientific data from field based study, GPS coordinate data, satellite imageries, maps, legacy data etc which objectively assesses the overall impact of the watershed development programmes in the region. The Department of Land Resources, Ministry of Rural Development (MoRD),Government of India, has assigned the GIS based evaluation using satellite imageries, in 7 blocks in 33 villages covering a total area of 13,500 ha in Barmer District, implemented under 7th phase, for about 27 watershed projects. In eight phase, 47 watershed projects
