“…These rivers have an essential role in the irrigation of this region for growing crops and fodder (Bharti et al 2017a, b). However, due to poor soil quality, limited water availability, fodder scarcity, and extreme climate, agro-animal practices are traditional and have low productivity (Acharya et al 2011;Charan et al 2013;Bharti et al 2017a, b;Kumar et al 2021). Therefore, the region's agriculture sector should be significantly and substantially developed with greater efforts on the production scale.…”

A total of seventy irrigation water samples were collected from Leh, Ladakh, India, to determine their hydrochemistry profile and water quality for irrigation purposes. Water quality indices such as total hardness (TH), residual sodium carbonate (RSC), potential salinity (PS), permeability index (PI), Kelly's ratio (KR), sodium absorption ratio (SAR), corrosivity ratio (CR), and chloroalkaline indices (CAI) were measured. The Piper diagram, Durov's diagram, and United States Salinity Laboratory (USSL) diagram were drawn to determine the water types, ion exchange processes, and rock–soil–water interaction. The findings indicated that the hydrochemical characteristics of irrigation water are naturally alkaline. Furthermore, water quality parameters revealed that the study area’s surface water is suitable for irrigation purposes, despite relatively high TH and MH levels. The level of CR indicated that water should not be transported using metal pipes. The CAI and Durov's plot indicated direct ionic exchange processes controlling water chemistry. Additionally, this irrigation water is mainly dominated by the Ca2+–Cl−–SO42−, Na+–K+–CaCO3 + HCO3−, and Na+–K+–Cl− type, which indicates silicate rock weathering along with some anthropogenic input. The USSL salinity diagram indicated a medium salinity and low Na hazard. Hence, it is concluded that the rock weathering cycle is the natural source of all the cations and anions, and these ions pass directly from water to rock and vis-à-vis, along with some input of anthropogenic activity.

Climate change and human interventions over the past few decades have significantly affected the groundwater resources in Ladakh Himalaya. Sparse or lack of suitable data and knowledge gaps are a major challenge in evaluating these impacts. Here, we synthesize the available data to assess the status of groundwater quantity, quality, withdrawal, and contamination in the Leh district of India. The study shows that glacier area has decreased by 40% whereas its volume has reduced by 25% since the Little Ice Age (∼1650 AD). The glacier melt, which influences the recharge, has reduced significantly. The growth of population by 15% per year, expansion of build-up area by 50%, and changes in the socio-ecology have further stressed the groundwater. The bore wells and groundwater draft have increased at ∼115 wells/year and ∼7 MCM/year, respectively. The increase of groundwater development by ∼26 times has reduced the reserves. Hence, for the sustainability of the resource, modeling and managing the impacts is imperatively required. In this direction, this paper provides guidelines for researchers, policymakers, and water users to develop an integrative consortium management strategy for the sustainable utilization of the groundwater.
