One of the well know strategies for increasing the water supply is rain water harvesting. Studies were conducted using house sizes and population factors of Khuskera-Bhiwari Neemrana Investment Region (KBNIR) for the rooftop rainwater harvesting. It is estimated that if rain water harvesting is achieved in 50 % of resident houses and all buildings likes hospitals, schools, community halls etc., then 100% of the drinking water requirement of KBNIR could be met from rainwater harvesting alone.

State has large part of desert or arid area (58% of total geographical area) and has low water resources in comparison to rest of the country. Any adverse climate change conditions are likely to have catastrophic effect on already fragile water resource system of the state. In this study attempts have been made to understand climate conditions of the state and to highlight isolated events of the past suggesting that climate change may be happening in the state. It is stressed that climate change modeling need to undertaken for different climate zones in the state. State-of-art tools like remote sensing and geospatial tools must be used to develop optimal water resource management strategies for different zones.

In this small study, various gemorphological parameters are covering the Bhyunder Ganga Catchment. The main object is to map the land system into further various Landform unit and features through geomorphic approach in Bhyunder Ganga Catchment. Geomorphologic maps were prepared using Satellite images (Landsat ETM+, TM, MSS, ASTER, SRTM) and digital SOI topographic sheet of the region; this was further updated during post field work. Digital Elevation Model (DEM) generation based on topographical sheet was prepared for creating relief map, slope map, aspect map and 3D visualization in addition to drainage map with the help of topographical sheets, the generation of various thematic layers has also been developed. Land Use/Cover over the study area has been analyzed for the time periods of 2008 .The major proportion in land use is the snow cover (53.20%). Other landuse are barren land (22%), dense forest, open forest, built up and water bodies occupy only 24.8% area of catchment. Various theme maps (erosion intensity, LST) were generated for GIS study analysis is done to analyze the instability and morphology of the catchment area.

The study has been done through remote sensing approach using SOI map of Dehradun Valley. The aims of this study are to detect land use changes between 2000 to 2009 using satellite images of Landsat (ETM + , TM, MSS), LISS­III, SRTM and digital SOI topographic maps have been used. The aim of this study is to produce a land use/ land cover map of Dehradun valley at two epochs in order to detect the changes that have taken place particularly in the built­up land and forest areas. Landuse changes have been detected by image processing method in EDRAS imagine9.3, ArcGIS9.3. Finally to predict the changes in urban habitants and landuse/landcover changes occurred. Monitoring of landuse/landcover changes which would help to plan development activities such as major schemes and their land requirements. The nine year time period of 2000 ­2009 shows the major type of land use change. Forest area is decreased 3.75 % and water (seasonal) decreased 9.5%. Most remarkable change has taken place in Built up area resulting in 112.4% growth in less than a decade period.

Water Security means regular access and equity to safe potable water for drinking, sanitation and hygiene thereby leading to an acceptable physical and social well being. Integrated water resources management (IWRM) practices are needed to create sustainable water security. IWRM is a conceptual stakeholder participatory framework that could manage and develop the water resources in a sustainable and balanced way. It is based on the principles of social equity, economic efficiency and environmental sustainability. IWRM has been globally accepted as the water management doctrine for the 21st century. This paper presents a critical review of IWRM approach and highlights the challenges related to Rajasthan. This state is considered to be most crucial due to the insufficient water resources. State receives an average annual rainfall of 575 mm. The surface water availability in the state is 16.05 billion cubic meter (BCM). Total annual replenishable ground water of the state is 11.94 BCM out of which the natural discharge is 1.11 BCM during non-monsoon period and net annual ground water availability is 10.83BCM. Agriculture dependency on ground water is 70-90 %. The per capita water availability for the state is 640 cubic meters which is very low according to international standard of 1000 cubic meter. Water security would lead to efficient water supply system, use of water saving techniques and improved irrigation practices. Special attention is required for rainwater harvesting and conservation techniques and re-use of waste water. Conclusions are drawn and recommendations made based on the current status of water resources of Rajasthan.
