The Ganges Basin is a part of the Ganges-Brahmaputra-Meghna (GBM) River Basin and is one of the most populated (600 million) river basins in the world. This study focuses on the Eastern Ganges Basin (EGB) and covers India (Bihar, Jharkhand and West Bengal), Bangladesh and the Nepal Terai. Poverty is acute in the EGB, where household incomes are low, food security is not assured and devastating floods (and also water shortages) occur too often. The EGB is underlain by one of the most prolific aquifers in the world. Yet, farmers struggle to cope with dry spells and droughts because of their inability to access groundwater. Huge untapped groundwater, surplus surface water, and enormous plains and fertile lands highlight the requirement of proper planning for groundwater management and governance to reduce poverty and assure food security. The aim of this report is to assist planners/policymakers in the planning and management of groundwater resources in the EGB. This report mainly discusses about hydrogeology, groundwater potential and challenges, and groundwater quality issues in the EGB. Moreover, it is an attempt to form a base for future work related to groundwater development, management and modeling in this basin.

Ground water is a precious natural resource in every aspect of human life from natural to artificial environment. Ground water is an indicator of regional development by improving the economic domain through intensive agricultural practices, and aesthetic value through sufficient ground water supply as drinking water, fertile soil, and healthy vegetation. However, ground water availability and associated human perceptions were the main themes of the present study. In this study, both primary and secondary data were incorporated to understand the human adaptation behaviour in drought-prone areas of the fringe of Chhotanagpur plateau region (Bankura-I and II blocks) to ground water storage. GWPZ mapping is a very important exposure to knowing the ground reality. So, the MCDM-AHP method has been developed based on the eight dominant conditioning factors viz. geomorphology, lithology, lineament density, soil, drainage density, LULC, average slope, and slope aspect using GIS analytics with field expertise. The output result was validated with comparing 105 inventory stations where 0.850 AUC value was good for accepting the GWPZ model. As a result, a major portion of the study area is dominated by poor to moderate possibilities of ground water level (ground water level drops 1–2 m during the pre-monsoon) due to Proterozoic granite gneiss formation over the study area. With comparing demographic status, it was not favourable for a healthy lifestyle. Agriculture dominated rural environment of Bankura-I and II blocks is far away from the modern digital environment that is why ground water has played a very crucial role in the field of development. Moreover, to build up a good level of ground water recharge zone through rainfall harvesting, and sustainable land use planning will be the best management practices. So, availability of ground water should be a positive sign of development in the field of the economic sector and sustainable human society.

The cluster-wise area of shallow and deep aquifer zones is used to estimate the potential of groundwater. The potential of the shallow aquifer zone is estimated at 4.61 MCM (million cubic meters) and for the deep aquifer zone at 17,509.03 MCM, while the total groundwater potential for both aquifer zones is estimated at 17,513.64 MCM. The Geographical Information System (GIS) was employed efficiently to estimate the subsurface volume of the lithological rock layers using cost-effective and time-saving techniques, while the Rockwork software integrated with GIS was successfully used to visualize the subsurface lithology and stratigraphy of the aquifer zones. The estimated potential of groundwater can be uncovered by using the alternative solar pumping system to improve the agricultural system in the study area, thereby reducing the migration rate, reducing poverty, and improving the socio-economic conditions of livelihood. In the future, too, it will be essential to design water quality studies to ensure the proper use of groundwater.
