Projects Worked On
The Middle East and North Africa have longstanding water supply and sanitation challenges. In 2011, US Agency for International Development (USAID) partnered with Development Alternatives Inc. to end the global freshwater crisis by implementing the Furthering the Blue Revolution Initiative (FABRI). This program helps create Middle East and North Africa Network of Water Centers of Excellence (MENA NWC). Designed and launched by USAID through FABRI, DAI has partnered with the UC Davis College of Agricultural and Environmental Sciences International Programs office to provide critical guidance on water resource and wastewater management in the formation of MENA NWC. The Center for Watershed Sciences is spearheading UC Davis participation in FABRI.
California’s complex water management system often defies comprehensive analysis. We summarize the results of a decade of quantification and analysis of this system from a hydro-economic perspective using the CALVIN Model.
Water resource management in California is often extensive and complex and deserves a comprehensive data and modeling approach. The Hobbes Project is a new effort to provide a venue for modelers in California and elsewhere to create an open, organized and documented quantitative representation of the state's intertied water resources system. Geocoded elements in this database can be interactively converted into tiered networks able to be solved by multiple modeling platforms depending on user preferences, with the appropriate translators. Many Hobbes tools will be web-based with exporting capabilities to the most common analytical and modeling software.
This study for the state Delta Protection Commission compared the effectiveness of using new remotely sensed measurement technology to estimate farmers' "consumptive water use," or the amount of irrigation water crops transpire and evaporate from the nearby soil.
This technical workshop in collaboration with the California Water and Enviornmental Modeling Forum (CWEMF). This workshop presents various alternatives for modeling the economics of water use and water scarcity within an agricultural production setting, with a particular focus on California.
Sea level rise, large-scale flooding, and new conveyance arrangements for water exports may increase future water salinity for local agricultural production in California’s Sacramento-San Joaquin Delta. Increasing salinity in crop root zones often decreases crop yields and crop revenues. Salinity effects are nonlinear and vary with crop choice and other factors including drainage and residence time of irrigation water. Here, we explore changes in agricultural production in the Delta under various combinations of water management, large-scale flooding and future sea level rise.
UC Davis researchers forecast the socio-economic effects of the drought on California agriculture for 2014 and beyond. Economists use computer models and the latest estimates of water deliveries, well-pumping capacities and acres fallowed. The researchers exploit new satellite remote-sensing technologies to estimate fallowed acreage as the drought unfolds.
The Center for Watershed Sciences in Collaboration with researchers from the Universidad Autonoma de Baja California in Ensenada conducted a Pre-feasibility Assessment for a Water Fund in the Region. A Water Fund in the Ensenada Region may result an attractive water management tool for government agencies, water utilities, urban and agricultural water users and non-governmental or conservation organizations.
The National Science Foundation is sponsoring an Integrated Modeling Workshop to explore ways to improve the development and application of modeling for multipurpose management of changing estuarine systems. The two-day workshop will bring together experts from Europe, Asia and across the U.S. Potential solutions will be identified and discussed from multiple perspectives: government, academia, NGOs, consultants and stakeholders.
This program quantifies agricultural production, land use, water use, economic value and employment using optimization approaches such as the SWAP model (http://SWAP.ucdavis.edu) and statistical information.
PSAH programs give an economic incentive or cash payment to owners or holders of forest land for providing hydrological services. The lands must establish and implement a sustainable development plan and set of actions and be attractive to providers and beneficiaries of these services. In this report, a overview of payments for environmental services is presented with a case study in the region of Acayucan, Veracruz.
This website provides preliminary information on irrigated land areas, water use and crop value over various hydrologic boundaries. Information from the California Department of Water Resources (http://www.water.ca.gov/landwateruse/anlwuest.cfm) on land and water use, and economic information from the SWAP model (swap.ucdavis.edu) for 20 crop groups are employed.
This research project was convened by the Center for Watershed Sciences at the University of California Davis with financial support from the California State Water Resources Control Board Office of the Delta Watermaster and other agencies. Its objective is to develop a better understanding of consumptive water use in the Delta by coordinating modeling, measurement, and other information from a variety of independent research and estimation efforts.
Advanced Hardwood Biofuels Northwest (AHB) is a consortium of Pacific Northwest university and industry partners led by the University of Washington. AHB is carrying out research and development to support a system that will use renewable feedstocks like hybrid poplar to produce a suite of products that are currently derived from petroleum. AHB will focus on the development of a renewable bio-based chemical industry. Developing poplar-based biofuels including jet fuel, diesel, and gasoline that can supplement existing fossil fuels is the long term goal. A bio-based chemical and fuel industry will revitalize rural communities through job creation and economic development, decrease the nation’s dependence on foreign oil, and move the nation toward a clean energy and product economy based on renewable materials with a low carbon footprint.
To more accurately estimate the threat posed by sea level rise and intense storms to coastal infrastructure, this research will provide assess coastal flood risk accounting for changing climate patterns, erosion rates, shifting beach forms, and vertical land movement. Methods will be developed to support site-specific, project level assessments of coastal vulnerabilities to sea level rise through integration of models of projected sea level rise and climate scenarios, coupled with local and regional-scale erosion rates and vertical land motion estimates.
This project integrates hydrologic and socioeconomic data into a water management decision support system using hydro-economic principles. Goals are to organize and exchange hydrologic and socioeconomic data; develop long-term hydrologic and socioeconomic scenarios; model a large, multi-objective metropolitan water system using hydro-economics; and identify and compare promising water management strategies.
The model employs a Multi-Agent-Simulation (MAS) framework and is designed to evaluate direct and indirect outcomes of climate change scenarios and policy interventions on farmer decision making, including annual land use, groundwater use for irrigation, and water sales to a water tanker market.
