Almost 40% of land in the world is considered drylands, which are the most sensitive areas to climate change and human activities. Representative Concentration Pathways (RCPs) projections data show an increase of drylands by 50% near the end of this century. With the expansion of drylands, and the increasing population in West Bengal (85° 40'E-88° 15'E longitudes and 21° 45'N-24° 45'N latitude), this puts pressure on water managers to accurately plan, prepare, and implement new measures for increasing water sustainability and sources of water. Future climate projections will require finding alternative and reusable water sources for present and future use. The goal of this study is to design a methodology to evaluate current existing groundwater resources, and to identify future potential zone for <strong>artificial groundwater recharge </strong>activities to improve<strong> </strong>groundwater storage during rain events. We also evaluate locations for <strong>rainwater harvesting</strong>, the state-of-the science of <strong>wastewater reuse</strong> and <strong>alternative crop</strong> rotations to minimize water use while maximizing production and benefits to farmers. Our work is applicable to other dryland areas around the world experiencing accelerated warming and desertification. </p>

According to the National Commission on Agriculture has categorized three types of drought. One of them is hydrological drought, due to the drought rural community are affected by availability of surface water, sub-surface water and ground water. This is why we can say that hydrological or agricultural drought is the silent natural threat or hazard of rural economy. Also, it impacts on crop area, crop production, environment by abnormal weather condition. In West Bengal, the few districts are drought prone. Bankura is one of them. In this paper, remote sensing based methodology prepared for identify and take management stratagem according to state label or district label. Prevention and preparedness means pre-disaster activities designed to increase the level of readiness and improvement of operational and institutional capabilities for responding to a drought.

Therefore, its causes are as diverse as its consequences, both of which vary with the nature of the flood prone environment. In the low lying parts of flood plains, atmospheric extremes, especially excessive rainfall- are the primary causes of most of the flood episodes. The river Kaliaghai was originated from the highlands of the Jhargram P.S in the Paschim Medinipur district. The combined flows of the Kaliaghai and kangsabati which meet at Dheubhanga in P.S.-Moyna in the district of Purba Medinipur is known as the river Haldi. The river Kapaleswari and Baghai are two main tributaries of the Kaliaghai. The Kaliaghai-Kapaleswari- Baghai drainage basin covers an area of 2145 Km 2 The lower parts of the basin comprising of 1576.25 Km

The present study's focus is climate change impact on land use / land covers change identification of Dangra sub watershed. land use/ land cover (LU/LC) can be defined by the ability of the physical and chemical properties of soil, drainage, relief, ground water, slope and climate of the area. Remote sensing and GIS analysis are used to collect, analysis and retrieve large volumes of spatially referenced data collected from different sources. The present study has utilized the analytical capabilities of GIS in generation of thematic map of land use / land covers of the sub-watershed. The study concludes that, land use condition depends on climate (Rainfall) condition. Maximum area of agricultural land and water body are occurred in the year 2010, beside the rainfall amount also high in the year.

To assess the productivity of soil physical & chemical properties of soil, drainage density and climatic condition are considered. The present study has utilized the analytical capabilities of Geoinformatics in generation of thematic information on productivity of Jamboni block.

But, unfortunately the humans are using that gift wastefully. The villages of the study area are fast heading towards a water crisis. The most part of the area have traditionally relied on local rainfall for meeting the water requirements for drinking, washing and other purposes and for agriculture. Its’ shortage is likely to be so acute that the future may fought on sharing of water resources among various villages. Geoinformatics use in Micro Watershed Management can provide the appropriate platform for convergence of multidisciplinary data from various sources for appropriate planning. Remotely sensed data provides valuable and up-to-date spatial information on natural resources and physical terrain parameters. Geographical Information System (GIS) with its capability of integration and analysis of spatial, aspatial, multi-layered information obtained in a wide variety of formats both from remote sensing and other conventional sources has pro...

The Dungra sub-watershed is located in Bankura and Puruliya district of West Bengal, which is one of the most drought affected region of the state. The study area is totally rainfed and ground water level is very high, that's why availability of water is an increasing problem. For the prioritization of watershed holistic integrated techniques involving geoinformatics has been found to be effective for watershed development. The prioritization is based on Morphometric parameters using Geoinformatics techniques. Morphometric analysis involves a set of parameters like; Aerial aspects, linear aspects, Relief aspects. The current study is taking up to investing the utility of satellite imageries of IRS-P6 LISS-III of October 2011. Based on Morphometric of 7 mini watersheds have been priorities for conservation and management of water resources.

Predictive models such as Universal Soil Loss Equation (USLE) and its subsequent Revised Universal Soil Loss Equation (RUSLE) are useful tools to generate the quantitative estimates necessary for designing sound conservation measures. This study focuses on the calculation of erosion using the Revised Universal Soil Loss Equation (RUSLE). All parameters are calculated on the base of remote sensing data. First to understand the relationships between plateau buildings related to climatic factors and erosion, while the second goal is to produce a precise erosion risk map for the whole region which is observed in this study. The result advocates for check dam construction at selected sites. Whereas the check dam sites are selected by analyzing the information experienced through analyzing the maps and imageries with RS &GIS techniques. © 2014 Published by Vidyasagar University.

The supply of groundwater is not unlimited and therefore its’ use should be properly planned based on the understanding of the groundwater systems behavior in order to ensure its sustainable use. Again a judicious use of groundwater, proper evaluation is required. A groundwater development and management program needs the analyses of a large volume of multidisciplinary data from various sources. Integrated use of remote Sensing and GIS can provide the appropriate platform for convergence of multidisciplinary data from various sources for appropriate planning. In the present study, an integrated remote Sensing and GIS based methodology is developed and tested for the evaluation of the groundwater resources of Dulung watershed, Paschim Medinipur District, West Bengal and a small part of the adjoining Jharkhand state. IRS 1D LISS-III satellite data of 4th February, 2008 along with other data s...

In the context of quality, potable water is always meager for present and future. The study is an innovative attempt towards the development of the watershed on the earth science platform. There after balancing of water resources for the domestic and agricultural uses has also been tried. The focus is mainly on the surface water for present use and groundwater for future. This management plan specially includes the socially and economically backward demographic conditions. The present study is an integrated approach for micro watershed wise development plan of the Kansachara sub – watershed.
