A geospatial technique‐based site suitability analysis for construction of water reservoirs in Arsha and Balarampur Blocks, Purulia

Abstract

Water security is a term associated with the availability of fresh water for all. However, this finite resource has certain other related factors, as water resource can act as a driver for development or underdevelopment. From ancient history to now, human civilization has been dependent on water resources, not only for drinking but for the maintenance of natural systems, for hunting and foraging, through to the growth of agriculture and industrialization. Moreover, the relationship between water resource and regional development becomes more prominent in those areas where this finite resource is scarce. In most dryland areas, water resource management becomes an integral part of regional policy for overall development. This study aims to understand the intensity of water resource scarcity and management through proper site selection in the southwestern part of West Bengal, particularly in Purulia district. The district is underdeveloped, as well as water stressed due to climatic, geological, and socioeconomic factors. Water scarcity in the district impacts agricultural productivity through wasteland generation, which also drives regional poverty and migration. This study also seeks to explain how sustainable development goals, such as climate change (SDGs 13), life on land (SDGs 15), and poverty (SDGs 1), are related to water security. With the help of a semi‐structured questionnaire, secondary data (census, 2011), and geographical information systems, we endorse the view that assessment and management of water through proper site selection can help drive integrated rural water security.

Probability Integral Method in the Influence of Ground Settlement on a Certain Construction Land

“…Among them, the shortest distance between the No. 1 goaf and the west side of Rundu construction land is about 168m, which is the most likely to have an adverse geological impact on the northwest side Rundu pharmaceutical construction land [4]. No.…”

Dynamic Analysis of Watershed Management and Sustainable Agriculture in Dryland Regions: A Case Study of Purulia District, West Bengal

“…This district is selected as the study area because it has a long history of water scarcity. The average rainfall in the study area ranges between 1,000 and 1,600 mm (Kar et al, 2020). The Draft District Disaster Management Plan by Office of the District Magistrate, Purulia (2021) reports that the average rainfall in the district is 1,357 mm.…”

Site suitability analysis for the construction of water reservoirs in drought‐prone areas of Bangladesh using geospatial techniques

“…From the catchment perspective, it is very important to realize that different types of small impoundments provide various types of ecosystem service that includes groundwater recharge, storage of floodwater, sediment trapping, nutrient retention/removal, support for food chains, fisheries production, habitat for wildlife, recreation, and micro‐climate stabilization (MEA, 2005; Rahaman et al, 2019). Therefore, to reverse the degradation of catchment's hydrological condition, water reservoirs have crucial importance, because of their multi‐dimensional ecosystem services, which not only improve the quality of catchment's water resources but also create opportunity for livelihood improvement (Kar et al, 2020; Suharyanto et al, 2020; Tsiko & Haile, 2011). Bangladesh Delta Management 2100 also emphasized water reservoir creation in the northwest region (General Planning Division, 2018).…”

“…In this process, a lot of spatial data is required to handle and analyze in a spatial decision making process with a multi‐criteria environment. Geographic information system and remote sensing techniques were found to be the most appropriate and reliable techniques to process a vast amount of geospatial data (Ahmed et al, 2021; Kar et al, 2020; Olabode et al, 2021; Suharyanto et al, 2020). In this study, we used these techniques to prepare and process the relevant criteria in the selection of water reservoirs.…”
