Abstract
The Great Rann of Kachchh (GRK) in Gujarat, India, is a hyper-saline environment where isolated island communities face acute water scarcity. This literature review synthesizes Scopus and Web of Science indexed research to evaluate an integrated geo-hydrological approach for sustainable water development. The analysis integrates geology, lithology, geomorphology, hydrogeology, and socio-economic dimensions including population distribution, livelihoods, and agriculture. Subsurface core analysis reveals marine transgression since ~18 ka BP, with fine-grained sediments rendering shallow aquifers saline. However, remote sensing and High-Resolution Electrical Resistivity Tomography (HERT) have successfully delineated buried palaeochannels containing confined artesian aquifers below 100 m depth, offering promising brackish water sources. The region hosts ~17,000 inhabitants across 48 hamlets, including pastoralist Jatts and Maldharis, and artisan Meghwals, whose livelihoods depend on animal husbandry, handicrafts, and tourism β all vulnerable to water insecurity. By integrating geo-hydrological and socio-economic understanding, this review proposes a multi-phase development framework encompassing geospatial prospecting, geophysical surveys, exploratory drilling, and community-based management. Critical knowledge gaps include groundwater age, recharge dynamics, and sustainable yield estimation. An integrated approach combining earth sciences and human geography is essential for ensuring long-term water security for the Great Rannβs island communities.
