Availability of water for agricultural use is one of the major factors determining agricultural production in the Western United States and is becoming an important factor in areas of the Southwest. In addition, water use and conservation is an important concern of the 1977 Soil and Water...

The interrelationship between food security of the United States and a diminishing water resource balances on the condition of that water resource, the quantity of other substitute resources, and the level of future technology. The answer to whether food supplies in the United States can be...

A multiperiod regional-national recursive system is formulated to model the interrelationships between agricultural production, resource use, and the environment, in a region nested within a national market. The system consists of three main components: a linear programming model of a region; an...

For the period of analysis, 1982 through 1987, the impacts on agriculture that result from increasing natural gas prices are examined. Two types of models are used in the analysis -- econometric and linear programming. These models are linked together so that a short-run multi-period analysis...

Good morning, ladies and gentlemen. My name is Burton C. English. I am a staff economist with the Center for Agricultural Development located in Ames, Iowa. My area of expertise is in agricultural economics and policy with a special emphasis in soil conservation. I wish to thank you for inviting...

Wind erosion is defined as the movement of soil particles resulting from strong turbulent winds. The movement of soil particles can be categorized as suspension, saltation, or surface creep. Fine soil particles can be suspended in the atmosphere and carried for great distances. Particles too...

The purpose of this paper is to elaborate on the basic assumptions that have been made or need to be made before the solutions for the 1985 RCA (Resource Conservation Act.) This paper will state the regions to be used in the programming and the assumptions used in the creation of the crop...

The Center for Agricultural and Rural Development (CARD) is developing a model to examine land use changes and their associated environmental and economic implications for the Southeast region of the United States. The model will be built as if there were two regions in the U.S. One region is...

With passage of the Food Security Act of 1985 (FSA85), Congress and the Administration set in motion the largest set of conservation measures since the inception of federal soil conservation programs. Although the FSA85 also has sodbuster, swampbuster, cross compliance and conservation easement...

In response to the Project Advisory Committee's inquiries, this note examines the consistency of using outputs from the National Inter-regional Agricultural Projection model (NIRAP) as inputs to the CARD/RCA linear programming model. To examine this, the paper first addresses the output that the...
