Research Project: SUSTAINABLE GROUNDWATER MANAGEMENT UNDER VARIABLE CLIMATE AND LAND USE CHANGE
2009 Annual Report


1a.Objectives (from AD-416)
The objective of this cooperative research project is to conduct research into integrated approaches to enhance the sustainable development and use of groundwater resources to support agriculture, industry, drinking water, and environmental requirements.


1b.Approach (from AD-416)
Research will be conducted in the Calera Basin, Zacatecas, Mexico; the Fort Cobb Basin and Rush Springs Aquifer, Oklahoma, USA: and the Ogallala Aquifer in the Southern High Plains of the USA. The research will involve broad stakeholder groups and diverse university, federal, state, and local researchers, educators, policy makers, and outreach specialists within each basin of interest. Methods will include geophysical and socioeconomic characterization utilizing remote sensing, field measurement, and surveys. Simulation models of surface and subsurface hydrology will be applied to climatic, technology, management, and policy scenarios of interest. Results of scenario analyses will be developed into decision support products, working closely with decision makers, and delivered to water managers and policy makers.


3.Progress Report

A collaborative team meeting was held in October 2008, in Houston, Texas, in conjunction with the Joint Annual Conferences of the American Society of Agronomy, Soil Science Society of America, Crop Science Society of America, and the Geological Society of America to discuss the annual plan of work. As an outgrowth of that meeting, the team pursued collaboration with the USDA Foreign Agricultural Service and the Mexico Mission of USAID to engage stakeholders in discussing their management decision, and policy options to improve water use efficiency and sustainability in the Calera basin. A workshop is being planned for October 2009. A masters-level graduate student was identified who will work under the direction of the Cooperator PI, with an internship period with ARS at the Bushland and El Reno laboratories to develop GIS and model input files for the Calera basin. Security clearance has been obtained for te student to work in the laboratories and the travel arrangements are being finalized. Climate and geographic data files were prepared by UAZ and sent to ARS for joint analysis. The ARS teams at El Reno and Bushland have entered into a joint effort to link surface and subsurface hydrologic models for application in the Ogallala, Rush Springs, and Calera aquifer assessments. The ADODR monitored progress of the project through meetings, e-mails, and telephone conversations.
