“…Additionally, 5% and 14% of blocks are at critical and semi-critical stages, respectively. The situation is particularly concerning in three major regions: north-western, western, and southern peninsular [4]. Based on a World Bank project report, groundwater pollution and climate change, particularly unpredictable rainfall in dry regions, are putting extra pressure on groundwater resources.…”

Groundwater is an essential resource, but it is becoming increasingly scarce and depleting rapidly, particularly in Karnataka. As a result, groundwater markets have emerged as an alternative strategy to manage this limited resource more efficiently and equitably. These markets enable farmers who cannot afford water extraction machinery to access irrigation. This article, aims to study present status of groundwater markets, temporal depletion of water table, groundwater security, economics and factors affecting water trade in Northern Dry Zone of Karnataka, mainly to compare with the results obtained in the past study [1] to analyze changes in scenario and have historical lessons. Multi-stage random sampling technique was used to select farmers, who were then categorized into water sellers, self-users, and buyers. Primary data was collected through a structured, pre-tested schedule and analysed using descriptive and logit regression analysis. Results show that unlike earlier study, buyers in present study owned wells. Depth of borewells has increased (overall 44%), resulting in increased drilling, deepening, and pumping costs. Very few farmers (8%) acknowledged over-extraction from their farms could also contribute to groundwater insecurity. While studying economics it was found that perennial crops had the highest economic rents (260, 610Rs/hr for sellers and buyers).Reason for participation in water market has shifted from no investment capacity to water scarcity compared to earlier study. So farmers could be motivated to participate in water markets instead of relying on new wells during water shortages to encourage optimal water use and reduce negative externalities like increasing wells.

“…Various methods of groundwater sustainability assessment have been thoroughly investigated; however, none of them are capable of directly and accurately assessing the state of groundwater under the influence of multiple factors such as hydrometeorology, topography, and the extent of anthropogenic activities [9,10]. Thus, several indirect methods are still being applied to assess groundwater sustainability.…”

Local-Scale Groundwater Sustainability Assessment Based on the Response to Groundwater Mining (MGSI): A Case Study of Da’an City, Jilin Province, China

Sustainable groundwater utilization is important for social and economic development. There is a need for groundwater sustainability assessment in small-scale areas lacking detailed mining data. Here, exploiting water level data series, we propose an indicator of groundwater sustainability based on the response to mining (MGSI) for better evaluation; it integrates groundwater data and spatio-temporal variability at a local scale. A decomposition coefficient was applied to decompose the pressure exerted by groundwater mining on the groundwater system for each monitoring well. It correlated with the groundwater response state. In Da’an City, Jilin Province, China, the appraised results revealed that the aquifer type exhibiting the greatest risk to groundwater sustainability changed from phreatic to confined during 2008–2017. The spatio-temporal distribution of different sustainability levels between and within the aquifers indicated that adjustment of the groundwater mining layout should be the focus of groundwater management in Da’an City. Additionally, the Mann–Kendall trend test and Sen’s slope trend analysis effectively explained the sustainable evolution of groundwater in Da’an City and confirmed the reliability of the MGSI method. The proposed method highlights the effects of groundwater mining on sustainability and helps us better understand the interaction between anthropogenic activities and groundwater resources.
