Effective management of water resources is crucial for sustainable development in any region. When considering computer-aided analysis resource management, geospatial technology, i.e., the use remote sensing (RS) combined with Geographic Information Systems (GIS) proves to be highly valuable. Geospatial technology more cost-effective and requires less labor compared ground-based surveys, making it suitable a wide range agricultural applications. Effectively utilizing timely, accurate, objective data provided by RS technologies presents challenge field management. Satellite-based measurements offer consistent information on hydrological conditions across extensive land areas. In this study, we carried out detailed focused addressing issues India through application GIS technologies. Adhering Preferred Reporting Items Systematic Reviews Meta-Analysis (PRISMA) guidelines, systematically reviewed published research articles, providing comprehensive analysis. This study aims explore practices goal enhancing their effectiveness efficiency. primarily examines current Indian sustainability. We revealed that considerable has used multispectral Landsat series data. Cutting-edge like Sentinel, Unmanned Aerial Vehicles (UAVs), hyperspectral have not been fully investigated assessment monitoring resources.

Rainwater harvesting (RWH) has the potential to enhance sustainability of ground and surface water meet increasing demands constrained supplies, even under a changing climate. Since arid semi-arid regions frequently experience highly variable spatiotemporal rainfall patterns, rural communities have developed indigenous RWH techniques capture store rainwater for multiple uses. However, selecting appropriate sites RWH, especially across large regions, remains challenging since data required evaluate suitability using critical criteria are often lacking. This study aimed identify essential develop methodology select in Rajasthan (India). We combined GIS modeling (multicriteria decision analysis) with applied remote sensing as it assess land RWH. As assessment criteria, spatial datasets relating use/cover, rainfall, slope, soil texture, NDVI, drainage density were considered. Later, weights assigned each criterion based on their relative importance system, evidence from published literature, local expert advice, field visits. analyses used create maps (high, moderate, unsuited maps). The sensitivity analysis was also carried out identified check inadequacy inconsistency among preferences. It estimated that 3.6%, 8.2%, 27.3% area highly, moderately, unsuitable, respectively, Chauka implementation. Further, results show LULC is sensitive NDVI least parameter selected region, which suggests weight these parameters more likely decide outcome. Overall, this shows applicability GIS-based MCDA approach up-scaling traditional systems its other similar conditions, where offers increase resource availability reliability support livelihoods.

Water scarcity in arid and semi-arid regions is a critical global concern, necessitating innovative solutions to address increasing water demands these vulnerable areas. This study focuses on tackling this challenge by identifying classifying rainwater harvesting zones based their potentiality comparing the performance of two machine learning models, Artificial Neural Network (ANN) Random Forest (RF), for optimizing strategies. The area Purulia, district India. Extensive literature review was conducted identify key factors influencing harvesting. Open-source remotely sensed data were employed pinpoint potential zones. A multi-criteria decision-making technique applied assess importance various factors. Results indicated that rainfall, slope, runoff potential, soil, land cover, drainage density are six crucial selecting suitable locations. Approximately 2% unsuitable, 8% poorly suitable, 33% moderately 45% highly remaining 12% extremely Purulia. Two predictive models developed, with RF algorithm demonstrating nearly 99% accuracy. Finally, remedial techniques mitigating through discussed separately urban rural research article embraces comprehensive approach water-related concerns, offering replicable framework applicable globally, specific focus regions.

Rainwater collection systems play a crucial role in enhancing water availability regions with low precipitation. This study focused on identifying potential rainwater harvesting (RWH) locations drought-prone areas, specifically the Borena zone of Oromia and regional states Somali. research leveraged geospatial techniques multi-criteria decision analysis (MCDA) to assess feasible RWH sites. The dataset comprises essential factors such as rainfall, drainage density, slope, soil texture type, land use/land cover. These thematic layers serve inputs for analysis, each factor being weighted using Analytical Hierarchy Process (AHP) method based its significance. Reclassifying into subclasses facilitates suitability analysis. linear combination (WLC) technique is applied identify prioritize (PRWH) four classes: highly suitable, moderately suitability, unsuitable. Our findings reveal that 1% area, covering approximately 3288 km2, suitable RWH. Areas moderate constitute 12% (37,498 km2), while representing majority, encompass about 75% (242,170 km2). Additionally, 13% (41,000 km2) area deemed unsuitable proposed sites adaptable other low-precipitation regions. However, before implementing structures, further imperative. exploration socioeconomic variables future urged an in-depth examination various aspects environmental sustainability. paves way adapting align community needs life cycles also exploring socio-economic dimensions sustainability study. insights offer promising solutions address urgent issues associated scarcity. should include comprehensive site depictions, social economic activities, meticulous preparation cost-benefit
