Flood Forecasting & Mitigation: Worked with ILRI, Wageningen (Netherlands) to develop a
GIS-based system using the HydroSplash model for the Krishna River sub-basin. This tool enabled accurate flood forecasting at Prakasam Barrage, preventing ₹100–150 crore in annual flood damage and supporting better land-use and irrigation planning.
-
Sustainable Cropping Models: Under the Indo–US AKI initiative with the University of Florida and NC A&T, SWAT modeling was used in the Wargal watershed to suggest shifting from paddy to irrigated dry crops. This approach improved groundwater sustainability by 20% and enhanced farm incomes by ₹20,000–25,000 per acre.
-
Kolleru lake Restoration: Identified optimal lake boundary (5 ft) to safeguard 50,000 ha of cropland and 2 lakh villagers apart from preventing ₹250–300 crores in flood losses annually. This research directly influenced state water policy.
-
Mechanization Survey: A survey of 14,816 farmers in Andhra Pradesh revealed major gaps in subsidy access and emphasized the need for inclusive mechanization and custom hiring policies. An Android app was developed for on-farm data collection and analysis.
-
Solar-Powered Irrigation Systems: Designed crop-specific solar irrigation systems that reduced per-acre diesel and electricity expenses by ₹6,000–7,000 annually ensuring payback within five years.
-
Wastewater Reuse for Agriculture: Developed and deployed on-farm filter bed systems for Musi River water for improving irrigation quality, reducing nitrogen-induced groundwater pollution, and promoting sustainable peri-urban agriculture.
-
Water-Energy Nexus strategy: The spatial water footprint of major crops was assessed to identify suitable crop production zones in Guntur, Krishna, and Prakasam districts, which face moderate blue water scarcity. It was found that paddy uses 3,800 m³ of water per ton, leading to a recommendation for crop diversification and micro-irrigation to save 2,100 million m³ of water annually.
-
Policy Influence: Delivered data-driven recommendations across mechanization, crop diversification, water allocation, flood control, water-energy optimization and renewable energy adoption directly influencing state-level agricultural and environmental policies.
