Abstract

Water has been, is and will be most important natural resource for mankind. Such natural resource management becomes an important concern for 21st century due to high demand of water by rapidly increasing human population. Bundelkhand region is a hub of drought in Central India due to its erratic rainfall, hard rock terrains of archaen granite, absence of water interventions, undulating and rugged topography, dissected land, multidirectional slopes, highly eroded and shallow soil depth (25-150 cm). The study of last 20 years (2000-2019) reveals that 10 are severe drought years, 5 normal and 5 excess rainfall years. Most of the rainfall portion around >90% is received between June to September. Thus lack of agricultural water intervention structures, it was converted into runoff and generated drought for remaining period of the year. Around 85-90 % wells were dried in the region due to absence of groundwater recharge. In this way, this study was carried out for assessing the effect of v

Conclusion

Remote sensing and GIS based agricultural water interventions were found most effective and sustainable due to suitable site selection. These interventions generated approximately 25000 m3 water which was found sufficient for mankind and their activities. Adoptive method (Water table fluctuation) for groundwater recharge is a well accepted and convenient in hard-rock regions (Sharda et al., 2006; Dewandel et al., 2010; Glendenning and Vervoort 2010; Garg and Wani, 2012; Singh et al., 2014). Result of groundwater recharge reveals that adoptive technology was relevant and also satisfactory which supports to enhance the groundwater recharge for fulfil the requirements of mankind. Thus, this technology and method will be supportive for researchers and hydrologist to assessing the water scarcity problems and their solutions. Hence, such interventions and technology should be scaled up in other drought prone and semi-arid regions.
