The unique nature of the Ogallala Aquifer presents interesting and confounding problems for water policymakers who are coping with changing groundwater rules in Texas. The purpose of this article is to link previous efforts in water policy research for the Ogallala Aquifer in Texas with current collaborations that are ongoing with regional water planners. A chronological progression of economic water modeling efforts for the region is reviewed. The results of two recent collaborative studies are presented that provide estimates of impacts of alternative policies on groundwater saturated thickness, water use, net farm income, and regional economic activities.

AbstractThe issue of the “identity” of comparative education as a field of study or a discipline has been discussed for decades. Yet a kind of systematic structure that provides the basic principles for a coherent exposition of the field remains open. “Comparative education” is no longer conceived as an imaginary field’s coherence but, rather in terms of distinct branches of comparative and international studies in education and their underlying issues. Such an understanding is fostered through a deepened awareness of the basic problems, and successive solutions, constitutive of the emergence and further conformations of the comparative approach in education and the social sciences. Thus, academic journal publications of the past decade to shape education policy research within an Asia-Pacific context have been analyzed. Facts of increasing research collaboration, growing policy evaluation research, and growing attention to higher education have been presented. Significant difference in research impact and diffusion between Asia-Pacific and American education policy studies has been shown. Perspectives for future research directions in education policy research in an Asia-Pacific context have been suggested.

Agricultural production in the Great Plains provides a significant amount of food for the United States while contributing greatly to farm income in the region. However, recurrent droughts and expansion of crop production are increasing irrigation demand, leading to extensive pumping and attendant depletion of the Ogallala aquifer. In order to optimize water use, increase the sustainability of agricultural production, and identify best management practices, identification of food–water conflict hotspots in the Ogallala Aquifer Region (OAR) is necessary. We used satellite remote sensing time series of agricultural production (net primary production, NPP) and total water storage (TWS) to identify hotspots of food–water conflicts within the OAR and possible reasons behind these conflicts. Mean annual NPP (2001–2018) maps clearly showed intrusion of high NPP, aided by irrigation, into regions of historically low NPP (due to precipitation and temperature). Intrusion is particularly acute in the northern portion of OAR, where mean annual TWS (2002–2020) is high. The Oklahoma panhandle and Texas showed large decreasing TWS trends, which indicate the negative effects of current water demand for crop production on TWS. Nebraska demonstrated an increasing TWS trend even with a significant increase of NPP. A regional analysis of NPP and TWS can convey important information on current and potential conflicts in the food–water nexus and facilitate sustainable solutions. Methods developed in this study are relevant to other water-constrained agricultural production regions.

Because of the decline of the Ogallala Aquifer, water districts, regional water managers, and state water officers are becoming increasingly interested in conservation policies. This study evaluates both short-term and long-term water rights buyout policies. This research develops dynamic production functions for the major crops in the Texas Panhandle. The production functions are incorporated into optimal temporal allocation models that project annual producer behavior, crop choices, water use, and aquifer declines over 60 years. Results suggest that long-term buyouts may be more economically efficient than short-term buyouts.

The Ogallala Aquifer underlies 45 million ha, providing water for approximately 1.9 million people and supporting the robust agriculture economy of the US Great Plains region. The Ogallala Aquifer has experienced severe depletion, particularly in the Southern Plains states. This paper presents policy innovations that promote adoption of irrigation technology, and management innovations. Innovation in Kansas water policy has had the dual effects of increasing the authority of the state to regulate water while also providing more flexibility and increasing local input to water management and regulation. Technology innovations have focused on improved timing and placement of water. Management innovations include soil water monitoring, irrigation scheduling, soil health management and drought-tolerant varieties, crops, and cropping systems. The most noted success has been in the collective action which implemented a Local Enhanced Management Area (LEMA), which demonstrated that reduced water pumping resulted in low to no groundwater depletion while maintaining net income. Even more encouraging is the fact that irrigators who have participated in the LEMA or other conservation programs have conserved even more water than their goals. Innovative policy along with creative local–state–federal and private–public partnerships are advancing irrigation technology and management. Flexibility through multi-year allocations, banking of water not used in a given year, and shifting water across multiple water rights or uses on a farm are promising avenues to engage irrigators toward more sustainable irrigation in the Ogallala region.

Adoption of mitigation measures to reduce greenhouse gas emissions may affect other members of the society, producing a situation of trade-offs. In this study, such a trade-off is has been analyzed using three aspects of the Canadian society: producers (farm level adopter), environment (through reduction in the GHG emissions),; and regional economy (including rest of the society through lost / gained economic activities). The nutrient management strategy involving the switching nitrogen fertilizer application from a combination of fall and spring application to a 100 percent spring application. Results suggest that the adoption of such a measure creates a 'win-win' situation, being both environmentally and economically desirable. Under the scenario, fertilizer expenditures decreased by $43 million (giving rise to an equivalent increase in farm income), GHG emissions (in CO2E) by 2.15 percent of the 2000 level of emissions, Canadian economy as a whole showed improvements, although on a regional basis the results were mixed.Key words: Canadian prairie agriculture; Greenhouse gases; Mitigation; Nitrogen fertilizer Use; Trade-off analysisThe Journal of AGRICULTURE AND ENVIRONMENT Vol. 11, 2010Page: 70-82Uploaded date: 15 Septembre, 2010

Abstract This symposium acknowledges the founders of W112 Reproductive Performance in Domestic Ruminants. The contributions they made laid foundation collaborative efforts that continued over the next half century. The W112 really began in 1969 as a rewritten project involving several Agricultural Experiment Stations. That original project was W-49, that had been in existence at least as early as 1958. Upon approval of the project renewal in early 1970, the project was renamed W112 Reproductive Performance in Domestic Ruminants. The list of names of participants is like a who’s who of reproductive physiologists, too long to enumerate here. Increasing knowledge of physiology and endocrinology were paramount during the early years. Development, improvement, and sharing of analytical techniques improved accuracy of results, safety of procedures, and knowledge to be gained from the research. Concurrently, mechanistic basic and applied studies involving oocyte development, ovulation, sperm development, fertilization, pregnancy, and parturition all brought new understanding of the reproductive biology of domestic species. A good deal of what we currently know of the reproductive biology of ruminant animals finds some basis in laboratories involved in W112 collaborations. The unique nature of these scientists resulted from their mutual respect. Many young scientists found mentors in W112 that assisted us in developing our own research programs. And the support has not ended with research collaboration. It has been common for project participants to share teaching resources and serve on graduate student committees for each other’s students, fostering future involvement in the project. The W112 began slightly more than 50 years ago. Those of us who have been part of this group share a hope that the multistate project named Reproductive Performance in Domestic Ruminants will still be meeting the same goals of collaboration and support among scientists working to further animal agriculture for another 50 years and more.
