AgWIT - Agricultural Water Innovations in the Tropics

Identify improvements in resource use efficiencies and environmental performance of key crops produced via alternative water and soil management strategies under rainfed and irrigated conditions; Determine crop physiological responses of biochar additions to soil using non -destructive optical and thermal sensing at multiple cales throughout > 20 agricultural crop development cycles; Develop/apply crop ecophysiological, hydrological, and biogeochemical models to evaluate innovative soil and water management strategies in relation to the plant - soil -atmosphere system; Evaluate and set priorities among strategies to increase water resilience through structured decision making workshops with local communities, producer groups and water management agencies.
