Description Rainfall variability and water scarcity continue to hamper the food and income security of smallholder farming
systems in poverty-affected regions. Innovations in soil and water management, especially in the drylands, are
critical for meeting food security and water productivity targets of Agenda 2030. This study analyzes how
rainfed agriculture can be intensified with marginal impact on the landscape water balance. The impact of
rainwater harvesting structures on landscape hydrology and associated agricultural services was analyzed in the
semi-arid Jhansi district of Bundelkhand region in central India. The Parasai-Sindh pilot watershed was subjected
to a 5-year (2012–2016) monitoring of rainfed system improvements in water availability and crop intensification
due to surface water storage (haveli system), check dams, and field infiltration structures.
Hydrological processes were monitored intensively to analyze the landscape’s water balance components.
Rainwater harvesting (RWH) structures altered the landscape’s hydrology, limiting average surface runoff from
250 mm/year to 150 mm/year over the study period. Groundwater levels increased by 2–5 m (m), alleviating
water scarcity issues of the communities in recurring dry years. Nearly 20% of fallow lands were brought under
cultivation. Crop yields increased by 10–70% and average household income increased from US$ 960/year to US
$ 2700/year compared to that in the non-intervention landscape. The combined soil–water–vegetation efforts
strengthened water resilience and environmental systems in agricultural landscape.
