Building cross-sectoral collaborations to understand the dynamic interactions across the water-energy-food nexus using new scientific knowledge to help stakeholders set objectives for freshwater management & transforming science into management solutions.
Improving water productivity and water use efficiency, irrigation and drainage management, agricultural water management, soil physics/soil hydrology, remote sensing application in hydrology, hydrological modelling at catchment scale, quantifying the impact of climate and land use changes on water resources, identifying the gap between water supply and demand and suggest management solutions to narrow the gap, and water, soil, and fertilizers management modelling and experimentation at field scale.
UKCEH Fellow, hydrologist and water resources management specialist. Long experience of being employed by both universities and research centres. Expert in catchment hydrology, irrigation, drainage, soil hydrology, soil physics, soil-water-plant –atmosphere relations, impact of land use and climate, change on water resources, water& food security and drought management.
