“…Results showed that technological developments increased borewell depth over the past 10 years in the Berambadi watershed. However, a recent study on hard-rock aquifers in Karnataka demonstrated that nearly 70% of all fractures occur within a depth of 100 m, and the probability of encountering fractures decreases considerably below 100 m [55]. Aubriot [18] indicated that farmers' willingness to drill deeper may be linked to social and prestige-related aspects.…”

Farmers' production decisions and agricultural practices directly and indirectly influence the quantity and quality of natural resources, some being depleted common resources such as groundwater. Representing farming systems while accounting for their flexibility is needed to evaluate targeted, regional water management policies. Farmers' decisions regarding investing in irrigation and adopting cropping systems are inherently dynamic and must adapt to changes in climate and agronomic, economic and social, and institutional, conditions. To represent this diversity, we developed a typology of Indian farmers from a survey of 684 farms in Berambadi, an agricultural watershed in southern India (state of Karnataka). The survey provided information on farm structure, the cropping system and farm practices, water management for irrigation, and economic performances of the farm. Descriptive statistics and multivariate analysis (Multiple Correspondence Analysis and Agglomerative Hierarchical Clustering) were used to analyze relationships between observed factors and establish the farm typology. We identified three main types of farms: (1) large diversified and productivist farms; (2) small and marginal rainfed farms, and (3) small irrigated marketing farms. This typology represents the heterogeneity of farms in the Berambadi watershed.

“…Additionally, factors such as terrain slope, geomorphology, lithology, precipitation, topo-graphic elevation, drainage, land use /land cover, and lineament often provide an indication of groundwater location Alrefaee, 2017). Given these circumstances, groundwater pros-pecting without proper hydrogeological surveys often leads to failures due to the complex geological structure and irregular nature of these water resources in crystalline rock environ-ments (Sivaramakrishnan et al 2015). For these reasons, the use of technologies that integrate con-ventional methods with modern techniques of remote sensing and geographic information system (GIS) has been helping to increase the accuracy of hydrogeological research results, as well as to delineate potential groundwater zones in this type of region (Das, 2017).…”

Wells drilling process in fractured-bedrock aquifers is a difficult task. Extreme variations in lithology and structure features, as well productive water zones sited at preferential points make geological and geophysical investigations difficult. To contribute to the understanding of the process of groundwater zones occurrence in fractured-bedrock aquifers, this paper develops a drilling prospective model by using regression analysis, whose parameters were calibrated according to the photogeological and cartographic analysis of 113 drilling points in the states of Rio Grande do Norte, Paraíba, and Ceará. The effectiveness of the resulting model was assessed through a sample of 43 additional drillings, which were carried out aiming at the distribution of water to the communities in the semiarid region of Brazil. The obtained results indicate the model as an important tool in the drilling process, with direct implications on the logistics costs of water well site location and consequent attendance to the population that needs the water.

“…Groundwater is always found mainly in the sub-surface core spaces under the earth's surface, starting from the water table level and is appreciably difficult to extract through some measures put in place. Hence, adequate technology and energy are needed to bring the water from the ground to the surface for collection [5].…”

The study examined the types of pumps used in supplying water to buildings, assessed the factors affecting the adoption and use of photovoltaic solar water pump and the perception of stakeholders on the use of the photovoltaic solar water pump in the study area. These were done to assess the effectiveness of the use of photovoltaic solar technology to improve the availability of water for the use of the building occupants. The study was carried out in Ile-Ife Region, Osun State, Nigeria. Stratified random sampling was used to categorize the selected residential buildings based on their distance limits to the locations of boreholes, 1-300m, 301-700m, and 711-100m respectively. Systematic sampling was further used in the selection of residential buildings and respondents in the study area. A total of 125 questionnaires were administered on the respondents and the data collected were analyzed using both descriptive and inferential statistical methods. The result shows that a very significant proportion of the respondents, 83.33% depended on wells and boreholes while 73.33% of the wells/boreholes used in the study area had pumping facility. A large proportion of the boreholes in the study area had photovoltaic facilities and were majorly (60%) donated by the government. The most significant factor that influenced the adoption and use of photovoltaic solar water pumps was the level of technical know-how (mean score of 4.1167) and the most ranked benefit had from the use of the facility was less time spent in collecting water (mean score of 4.3583). To foster the availability of quantitative and qualitative water for the use of the building occupants through the provision of photovoltaic water supply, efforts are direly needed to take advantage of the tropical environment of the study area, to ensure optimum performance and security of the facility to drastically reduce dependence on the national grid.
