Water harvesting is a critical component of any ap-proach to alleviating India’s water crisis. Traditional rainwater harvesting systems are found in every region of the country. Haveli is one such system found in almost every village in the Bundelkhand region, Uttar Pradesh, India. A defunct Haveli in the Parasai–Sindh watershed of Jhansi district, Uttar Pradesh, was rejuvenated by providing a cement concrete core wall to the earthen embankment to address the problem of breaching, and the existing outlet was also expanded. This study was conducted from 2013 to 2019 to analyse the hydrology of the rejuvenated Haveli and to understand its impact on surface-water availability and recharging ground-water. The study period was divided based on long-term southwest monsoon (SWM) as wet (SWM > 20%), nor-mal (SWM ± 20%) and dry (SWM < 20%) years. It was found that the Haveli could harvest about 1.91–2.0 times, 1.13–1.72 times and 0.2 times its capacity during a wet, normal and dry year, respectively. There was a 1.41 m difference in hydraulic head between pre and post-Haveli rejuvenation in a wet year, whereas, a normal year, the difference was 2.71 m. © 2023, Current Science.

Impact assessment of rainwater management interventions on land use land cover changes in Parasai-Sindh watershed of Bundelkhand Region, Central India
(Elsevier B.V., 2024) Liansangpuii; Ramesh Singh; R.M. Singh; K.N. Singh; S.K. Kar
Rainwater Management (RWM) interventions were implemented to address the scarcity of water and to restrict the degradation of land resources in the Parasai-Sindh watershed covering an areal extent of 1246 ha located in Jhansi district of Bundelkhand region, Central India. The region is constrained by several factors, the most significant of which is its high vulnerability to natural disasters and poor infrastructure development, resulting in low agricultural production and precarious livelihoods. This study's goal was to evaluate the impact of RWM intervention on groundwater dynamics and the changes in LULC that it has brought about. A total of 380 dug wells were monitored to investigate the ground water dynamics. Integration of Remote Sensing (RS) and Geographic Information Systems (GIS) were used to prepare LULC maps using Landsat images. The changes in LULC were studied before and after the implementation of RWM interventions. The study revealed enhanced groundwater availability for agricultural and domestic applications. Due to increased water availability, a significant portion of fallow land was converted into cropland. Built-up land coverings have also increased in the watershed. A decrease in the areal extent of barren rocky and scrubland was witnessed over the study period. The area under plantation was also increased.The study underlines the relevance of RWM interventions in restoring watershed land cover, assisting in poverty alleviation, and providing long-term livelihood. © 2024 Elsevier B.V.
