My work focuses on putting together modern agricultural water management solutions to improve resource efficiency in irrigated agriculture. Resource efficiency aims to decouple economic growth from environmental burdens. When this concept is applied to irrigated agriculture, it requires that design and management of irrigation systems enable growers to enhance the economic profits from farming activities, without generating adverse environmental effects.
I help farmers optimize soil, water, and energy management, and find best practices for efficient and sustainable irrigation. When scaling-up efforts to the district and project level, I use analytical approaches for performance evaluation and modernization of irrigation delivery systems. My ultimate goal is to improve water management in California's irrigated agriculture, using problem-solving approaches in cooperation with growers, farmers’ organizations, county advisors, and water management agencies.
- Estimating actual evapotranspiration of vineyards with different aspects and slopes by surface renewal method
- Estimating evapotranspiration of alfalfa (ETr) by weighing lysimeters, and evaluating the standardized reference equation for ETr
- Development and validation of a methodology for auditing performance and planning modernization in pressurized irrigation delivery systems (MASSPRES — Mapping System and Services for Pressurized Irrigation), in cooperation with the FAO Land and Water Division and the International Center for Advanced Mediterranean Agronomic Studies
