“…In terms of GWR, sandy soils are preferable to clayey soil since water can penetrate them more quickly. Factors like the roots systems of vegetation and the interception capability of canopies contribute to the increasing GWR that results from the conversion of forests or native vegetation to controlled land use systems [101]. The canopy impact and increased infiltration capacity of forest systems cause surface runoff to be lower than that of controlled land use types.…”

“…Forest ecosystems are less effective in recharging because their evapotranspiration rates are higher than those of controlled land use categories [25]. Native vegetation is more efficient in extracting soil moisture compared to managed LULC like crops and grasses, resulting in increased GWR [101]. After a forest is converted to another LULC type, the GWR is chiefly affected by soil texture, with sand-textured soils showing a more pronounced effect.…”

“…After a forest is converted to another LULC type, the GWR is chiefly affected by soil texture, with sand-textured soils showing a more pronounced effect. The aridity index determines GWR changes after LULC change, with more arid environments experiencing stronger recharge changes [101]. Several thematic maps were created using toposheets from the Survey of India and imagery from the Indian Remote Sensing-1C.…”

“…Different land uses impact GWR rates differently. In arid areas, replacing grassland with woodland and cropland can decrease recharge rates by 70% and 250%, respectively, while in humid climates, reforestation and agricultural use of areas originally designated as grassland results in reductions of 20% and 60% [101]. The hard rock aquifers are significantly governed by the geological structures, especially the infiltration, specific capacity, yield flow, water level, thickness of unsaturated/saturated zone, etc.…”

Extensive use of groundwater is a result of the growing population; in relation to this, studies have focused on groundwater conservation measures. This study identified groundwater artificial recharge zones (GWARZs) in the upper Manimuktha sub-basin through the application of remote sensing and GIS. A spatial analysis using the analytical hierarchical process (AHP) and weighted overlay analysis (WOA) was employed by integrating several spatial thematic layers such as geology, geomorphology, aquifer thickness, lineament density (LD), drainage density (DD), soil, slope, rainfall, and land use/land cover (LULC) in order to classify the GWARZs. The geomorphology along with lithology, higher aquifer thickness, low lineament densities, higher drainage densities, and gentle slope regions, were identified as suitable areas for artificial recharge zones. The study area was divided up into five classifications based on the integration analysis: excellent (41.1 km2), good (150.6 km2), moderate (123.9 km2), bad (125.5 km2), and very poor (57.7 km2). Excellent and good GWARZs were identified in the eastern and central regions of the study area. The final outcomes of this research were evaluated with seasonal electrical conductivity (EC) variations. The majority of samples with minor seasonal EC variations were observed in the excellent and good GWARZ categories. The results showed that the spatial analysis tool is useful for GWARZ delineation and sustainably managing groundwater resources.

“…Groundwater recharge zone and spring protection zone are a group of this zone. The delineation of groundwater recharge zones is important in saving and protecting groundwater resources and aquifer management [7]. The delineation of the spring protection zone is much simpler, simply the radius of 200 m from springs.…”

This paper aims to find a new groundwater conservation zone concept in Indonesia by improving groundwater zoning by considering groundwater recharge changes. The previous zoning criteria only used groundwater level decrease and selected groundwater quality parameters. The ideas of this new concept are related to actual conditions, in terms of groundwater recharge changes due to global climate changes that control the precipitation frequency and in terms of land use changes that control groundwater recharge quantity. The changes are dynamically altered due to anthropogenic interactions. Based on Decree No. 31 2018, the groundwater conservation zone is based on three criteria: the decline of the groundwater table, the groundwater’s physical quality, and the apparent effect on the environment. This research will improve the criteria by suggesting some improvements to that approach: firstly, the application of modeling in calculating the groundwater decline rate, secondly the investigation of the effect of recharge decline due to land use change, and lastly to include recommendations on each zone in the groundwater conservation zone. This new concept is expected will revise the previous Decree that according to the consensus approach is not a scientific approach
