Research Project: A Systems Approach to Improved Water Management for Sustainable Production

Location: National Programs

Project Number: 0500-00095-001-00-D
Project Type: In-House Appropriated

Start Date: Jul 1, 2017
End Date: Jun 30, 2022

Objective:
Objective. 1: Develop a production system decision support toolkit for water management by producers that accounts for interacting GxExM factors. Objective 2. Develop technologies to enhance the sustainability of water resources for crop production that account for the processes governing movement, storage, quantity and quality of water and water re-use. Objective 3. Quantify and enable management of the effects of new water management strategies on crop production responses by assessing genotype x environment x limited-water and water re-use management (GxExM) interactions for different land use, management, and climate scenarios at field to watershed scales. Objective 4. Develop effective systems-management practices for weed control in waterways associated with agricultural irrigation systems for arid regions of the western U.S. Objective 5. As part of the LTAR network, and in concert with similar long-term, land-based research infrastructure in the California region, use the California LTAR site to improve the observational capabilities and data accessibility of the LTAR network and support research to sustain or enhance agricultural production and environmental quality in agroecosystems characteristic of the region. Research and data collection are planned and implemented based on the LTAR site application and in accordance with the responsibilities outlined in the LTAR Shared Research Strategy, a living document that serves as a roadmap for LTAR implementation. Participation in the LTAR network includes research and data management in support of the ARS GRACEnet and/or Livestock GRACEnet projects. Subobjective 5.1: Create “business as usual” and “aspirational’ production and ecosystem service system scenarios as outlined by the LTAR common experiment. Assess the sustainability of both systems and develop new strategies to enable greater sustainability.

Approach:
Headquarters held project established to hold funds until new unit in Davis, California is established to carry out objectives of research.
