Notably, in locales such as the Southern Hau River Region (SHRR), land subsidence rates as high as −10 cm/year have been documented, primarily associated with excessive groundwater extraction. Previous investigations have corroborated this relationship through the congruence between groundwater drawdown cones and areas of subsidence detected via InSAR (Interferometric Synthetic Aperture Radar) or through coupled Terzaghi consolidation theory-groundwater flow numerical modeling. This study extends the understanding of subsidence drivers in the SHRR beyond the groundwater level declining, encompassing tectonic activity, geological - lithological features, and landuse. Utilizing geostatistical analyses based on individual InSAR monitoring points, the study evaluates the respective contributions of these factors to land subsidence in the SHRR.

Findings from the study have been used to classify the basement complex aquifers of sub-Sahara Africa into three categories: marginally productive, low productive, and moderately productive. Weathered and fractured zones were found to be bright spots for groundwater storage, and aquifer productivity correlates with topography and the thickness of the weather zones. Most of the boreholes located on the low topographic heights were found to have the highest groundwater discharge, transmissivity, and hydraulic conductivity. Further, the study showed that the popular models used for estimating aquifer properties are unsuitable for basement complex aquifers. The results of the models are exaggerated when compared to the pumping test results. Cases of dry holes or poorly performing wells in the basement complex terrain may be attributed to the exaggeration. Consequently, two new and novel quantitative models were proposed and tested for evaluating the productivity parameters of basement aquifers of SSA for optimal selection of sites for groundwater development. The aquifer productivity maps computed with the new quantitative models show striking similarities to those computed from the pumping tests results and confirmed the appropriateness of the new quantitative models.

This study investigates the relationship between water table depth (WTD) and ecosystem productivity across India, considering the variation in irrigation practices, land use and climate types, from 2000 to 2021. We employ Ecosystem Water Use Efficiency (WUE<sub>e</sub>), the rate of carbon uptake per unit of water consumed, to examine these interactions at different spatial scales. Our findings reveal a strong link between WUE<sub>e</sub> and WTD. Shallower WTD regions, such as the lower Himalayas and Northeast India with forests and dominated by a wet/humid subtropical climate, exhibit higher WUE<sub>e</sub> (1.5–3.5 g C/kg H<sub>2</sub>O). Whereas deeper WTD regions like northwest India, characterized by shrublands and an arid climate, display lower WUE<sub>e</sub> (<1 g C/kg H<sub>2</sub>O). This suggests vegetation in arid/semi-arid regions shows higher sensitivity to water availability compared to wetter areas.

The major purpose of this research is to analyze aquifer vulnerability in Bangladesh's north-central area (Mymensingh) using conventional and modified DRASTIC modeling. Seven influencing hydrogeological factors were employed to develop and integrate conventional DRASTIC modeling: soil media, net recharge, aquifer depth, aquifer media, topography, hydraulic conductivity, and influence of vadose zone, while land use and lineament density were used with them for modified DRASTIC modeling. The findings from four vulnerability analysis detected 29.56% (93.35 sq.km), 22.24% (83.12 sq. km), 28.52 (106.93 sq. km), and 37.6% (140.55 sq.km) of the study area as high to very high vulnerable zones for groundwater pollution. Lower groundwater depth, higher hydraulic conductivity, moderate to high groundwater recharge, dense lineaments, dense settlement, agricultural land, and inland waterbodies together might indicate a high vulnerability in the research area. The validation results based on EC and nitrate levels show that conventional (r = 0.884, p ≤ 0.01; r = 0.951, p ≤ 0.01) and modified DRASTIC models (r = 0.868, p ≤ 0.01; r = 0.840, p ≤ 0.01) have a stronger association with unconfined aquifers, than confined aquifers.
