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.

评估干旱易发地区的地下水状况和人类感知:以西孟加拉邦(印度)Bankura-I 和 Bankura-II 区块为例

从自然环境到人工环境,地下水是人类生活各个方面的宝贵自然资源。地下水是区域发展的指标,通过集约化农业实践改善经济领域,通过充足的地下水供应作为饮用水、肥沃的土壤和健康的植被而具有美学价值。然而,地下水可用性和相关的人类感知是本研究的主要主题。在这项研究中,主要和次要数据都被纳入以了解人类在 Chhotanagpur 高原地区(Bankura-I 和 II 区块)边缘干旱易发地区对地下水储存的适应行为。GWPZ 测绘是了解地面现实的一个非常重要的途径。所以,MCDM-AHP 方法是基于八个主要条件因素开发的,即。地貌学、岩性、线性密度、土壤、排水密度、LULC、平均坡度和坡度,使用具有现场专业知识的 GIS 分析。输出结果通过比较 105 个库存站进行验证,其中 0.850 AUC 值适合接受 GWPZ 模型。因此,由于研究区元古界花岗岩片麻岩的形成,研究区的大部分地区可能存在低到中等的地下水位(季风前地下水位下降 1-2 m)。通过比较人口状况,它不利于健康的生活方式。Bankura-I 和 II 区块以农业为主的农村环境远离现代数字环境,这就是地下水在发展领域发挥非常关键作用的原因。此外,通过雨水收集和可持续的土地利用规划建立良好的地下水补给区将是最佳管理实践。因此,地下水的可用性应该是经济部门和可持续人类社会领域发展的积极标志。
