“…In this work, a mix of RS and GIS methods was used to delineate the groundwater and agriculture potential zones. These are one of the most cutting-edge techniques and are also economical since it generates data that is suitable and of excellent quality for this kind of assessment [22][23][24][25][26][27]. Seven thematic layers namely Geomorphology, Soil, Slope, Drainage Density, Land Use/Land Cover, Lineament Density, and Geology were created for groundwater potential zonation based on the availability of groundwater, and six thematic layers namely Digital Elevation Model (DEM), Slope, Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST), Soil Moisture Index (SMI), and Rainfall were created for agriculture potential zonation as these factors affect the potentiality for agriculture.…”

Groundwater is one of the most valuable natural resources on the planet, sustaining all human activity. It is necessary not just for human survival, but also for a region’s economic and social advancement. Also, agriculture and allied businesses provide a living for more than half of India’s population. Long-term advantages from sustainable agriculture will be necessary to achieve sustainable resource development and management. For successful agricultural and groundwater management, it is vital to assess the groundwater and agricultural potential of an area. This research work may contribute to optimizing the choice of location for future drilling and increase the chances to take water from productive structures which will satisfy the ever-increasing water demand of the local population, especially for agriculture. The current study is an attempt to assess the groundwater and agriculture potential zones in Haryana’s southern region of Mewat district. In order to achieve the objectives, thematic layers such as geology, geomorphology, lineament density, slope, drainage density, soil, and land use/land cover of the research region are prepared for the mapping of groundwater potential zones. For agriculture potential thematic layers such as Digital Elevation Model (DEM), Slope, Rainfall, Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST), and Soil Moisture Index (SMI) were prepared. To combine all thematic layers, an analytical hierarchy process (AHP) assessment approach is applied. Individual themes and their accompanying categories are awarded a knowledge base weightage ranging from 1 to 5 according to their suitability to hold groundwater and potential for agriculture. All thematic maps are combined into a composite groundwater potential and agriculture potential map of the research region using the weighted overlay function. The groundwater potential map and the agriculture potential map were further subdivided into four categories, ranging from very low to excellent potential zones. It has been found that 69% and 60% of the area has moderate to good groundwater and agriculture potential, respectively, and 20% and 22% of the area has excellent and agriculture potential, respectively. This groundwater and agriculture potential information will help identify acceptable places for water extraction and efficient farming practices.

Groundwater is one of the most crucial natural water supplies because of continuously directly or indirectly supports many domestic, agricultural, and industrial activities but is now being degraded due to various causes. <i>Therefore, this study aimed to iddentfy and map the factors that determine groundwater potential and produce a groundwater potential zones map for Genale-Dawa Bale Sub-Basin.</i> Accordingly, in this study, ten (10) factors affect groundwater potential at varying degrees namely: rainfall, geomorphology, LULC, lithology, soil texture, slope, elevation, topographic wetness index, drainage, and lineament density were used. Criteria weights and rankings were assigned based on expert opinion, literature review, and field survey experience, using Analytical Hierarchy Process (AHP) and ArcGIS 10.3 software to map potential groundwater zones. The results show that thematic factors such as rainfall, geomorphology, LULC, lithology, soil texture, slope, topographic wetness index, elevation, drainage density, and lineament density affect groundwater potential with weight values of 24.2%, 18.7%, 10.7%, 13%, 7.9%, 6.9%, 3.8%, 3.8%, 5.4%, and 5.7% respectively in the study area. Maps of groundwater potential zones classified into five categories: very low 366,001.80 ha (24.36%), low 249,151.07 ha (16.58%), moderate 271,817 ha (18.09%), high 278,343.13 ha (18.53%), and very high 337,194.06 ha (22.44%) for the Bale Zone and the Genale-Dawa Sub-Basin. The low to very low groundwater potentiality has been seen on the map at different distances due to the presence of hills and steep slopes, rock outcrop surfaces, clay soil textural class, low rainfall areas, very high drainage density, low lineament density, bare land are the main reasons. The validation analysis revealed a 91% confirms the very good agreement between the groundwater inventory data and the developed groundwater potential zone. The groundwater potential zones assessment and map of the current research results serve as a baseline information for planners, decision-makers, and adopters of sustainable management options, to identify suitable sites for groundwater exploration, and initial for further studies. Further studies, detailed water chemistry surveys, geophysical surveys at potential drilling sites, and grade analysis should recommended.
