Adams, B. M.; Lacewell, R. D.; Condra, G. D. (Texas Water Resources Institute, 1976-06)The Arab oil embargo of 1973 awakened the world to the reality of energy shortages and higher fuel prices. Agriculture in the United States is highly mechanized and thus energy intensive. This study seeks to develop an ...

Condra, G. D.; Lacewell, R. D.; Hardin, D. C.; Lindsey, K.; Whitson, R. E. (Texas Water Resources Institute, 1979-03)Public concern over the potential effects of energy price increases on the U.S. food and fiber system has been dramatically justified in the Trans Pecos region of Texas where a 450 percent increase in the price of natural ...
-
Cornforth, G. C.; Lacewell, R. D. (Texas Water Resources Institute, 1981-12)The Bureau of Reclamation has approved a program for farmer storage of surface irrigation water in Elephant Butte Reservoir, New Mexico. This program would allow individual farmers to store part of their annual surface ...

Ellis, J. R.; Teague, P. W.; Lacewell, R. D. (Texas Water Resources Institute, 1982-12)This study estimated the expected regional impact and economic feasibility of a proposed water accumulation or water saving option for agricultural producers operating in the Elephant Butte Irrigation District in southern ...

Muncrief, G.E.; Lacewell, R. D.; Cornforth, G. C.; Pena, J. G. (Texas Water Resources Institute, 1983-02)The chief sources of groundwater for the Texas Winter Garden are the Carrizo (Dimmit, Zavala, Frio, and LaSalle Counties) and Edwards (Uvalde County) Aquifers. The major user of groundwater in the region is irrigation. ...

Zacharias, T.; Taylor, C. R.; Lacewell, R. D. (Texas Water Resources Institute, 1980-09)The U.S. Army Corps of Engineers (COE) has proposed a project that would reduce the flow from saline springs and seeps within the groundwater alluvium of the Red River Basin. While the amount of salts moving through the ...
-
Zavaleta, L. R.; Lacewell, R. D.; Taylor, C. R. (Texas Water Resources Institute, 1979-03)Agricultural production and associated economic effects of irrigation on the Texas High Plains are seriously threatened by a rapidly declining groundwater supply and a swift upward trend in energy costs. To optimize the ...
-
Lacewell, R. D.; Condra, G. D. (Texas Water Resources Institute, 1976-06)Agriculture is a major income-producing sector in the Texas economy and a large part of this economic activity originates in irrigated crop production. For example, in 1973, 50% of all grain sorghum and 46% of all cotton ...
-
Condra, G. D.; Lacewell, R. D. (Texas Water Resources Institute, 1977-01)Cropping pattern shifts in many aggregate linear programming (LP) models need to be constrained due to institutional, marketing machinery, and price uncertainty factors. The purpose of this study was to estimate constraints ...

Petty, J. A.; Lacewell, R. D.; Hardin, D. C.; Whitson, R. E. (Texas Water Resources Institute, 1980-05)Irrigation is a major contributing factor in crop production on the Texas High Plains. It is responsible for greatly increasing crop production and farm income for the region. Two factors, a declining groundwater supply ...
-
Williford, G. H.; Beattie, B. R.; Lacewell, R. D. (Texas Water Resources Institute, 1976-06)Reduced availability of groundwater in the Northern High Plains of Texas and Oklahoma is expected to have repercussions throughout the regional economy due to the reduction in agricultural income.
