Item Agricultural sustainabiltiy in the Texas High Plains: The role of advanced irrigation systems and biotechnology(Texas Tech University, 1998-12) Arabiyat, Talah S.The cunent state of ground water utilization in the Texas High Plains area is a reflection of the combined resuh of cunent economic, social and polkical factors. The main reason why ground water resources in the Texas High Plains are being used at a rate higher than the natural rate of recharge, is because of the revenues stemming from their cunent use being higher than the associated cost of extraction. However, water use in the Texas High Plains, given the critical dependence of the regional economy on this resource, is an inter-generational issue that must be evaluated in terms of the sustainability of agriculmral activities in the long-mn. For this reason, given the cunent state of economic, social and polkical factors, the sustainability of this resource needs to be better understood, given cunent and expected technological advances ki agriculmral production. In particular, advanced irrigation system technology can increase the efficiency of water utilization, and thus decrease the amount of water resources needed to produce a crop. However, these advanced irrigation system technologies can also induce the transition of previously irrigated cropland which is cunently under dryland production practices to revert back into krigation (Feng, 1992).Item Asset pricing and yield spreads in the commodity spot and futures markets(Texas Tech University, 2003-08) Arabiyat, Talah S.Not availableItem SOPHISTICATED IRRIGATION TECHNOLOGY AND BIOTECHNOLOGY ADOPTION: IMPACTS ON GROUND WATER CONSERVATION(AgBio Forum, 1999-11-02) Willis, David B.; Segarra, Eduardo; Arabiyat, Talah S.A county-wide dynamic optimization model is used to evaluate the potential contributions associated with the adoption of sophisticated irrigation system technology and anticipated biotechnological advances in crop production on ground water conservation. The results indicate that adoption of these technologies could contribute significantly to ground water conservation efforts.Item Techonology Adoption in Agriculture: Implications for Ground Water Conservation in Texas High Plains(Elsevier B.V, 2001) Johnson, Jason L.; Segarra, Eduardo; Arabiyat, Talah S.The impact of technology adoption (advanced irrigation technologies and anticipated biotechnological advances) on the sustainability of agricultural activities in the Texas High Plains of the US is evaluated in this study. Specifically, a county-wide dynamic optimization model is used to (a) determine optimal ground water use levels and cropping patterns, and (b) evaluate the impacts of irrigation technology and biotechnology adoption on ground water use. The results indicate that current cropland allocation and levels of advanced irrigation technology adoption are not close to optimal. Approaching the issue of sustainability. the results show that the net present value of returns trade-off to achieve ground water conservation, in terms of what producers would have to give up to achieve ground water supply stability, would be relatively small. © 2001 Elsevier Science B.Y.
