Potential Economic And Environmental Impacts Of Alternative Sediment Control Policies, Center For Agricultural And Rural Development, Iowa State University, Joseph C. Campbell Dec 1979

Potential Economic And Environmental Impacts Of Alternative Sediment Control Policies, Center For Agricultural And Rural Development, Iowa State University, Joseph C. Campbell

CARD Reports

This study focuses on the interaction of U.S. agricultural exports, regional patterns of farm production, and the problem of agricultural sediment. It also evaluates alternative policies in abating sedimentation of the nation's main river basins. One underlying hypothesis of the study is that changes in agricultural export demands cause shifts in the comparative advantage among producing regions within the United States and alter regional land use patterns, farm incomes, consumer food prices, and soil loss. Given this hypothesis, the study uses a mathematical model and two estimates of the U.S. 1985 agricultural exports to investigate if and ...

An Analysis Of American Agriculture Under Various Policy Alternatives For 1980, Center For Agricultural And Rural Development, Iowa State University, Ashok Chowdhury, Earl O. Heady

CARD Reports

Historically, the U.S. farm sector has been a leader in meeting the challenges of the world's growing food demand. American farmers produced an impressive 24 percent of the total world food and feed grains in 1977. They also contributed 53.6 percent of total world exports of these farm commodities in the same year. This achievement was possible through a combination of past governmental policies and technological developments. In the beginning cheap land and other inexpensive inputs encouraged farmers to increase agricultural production by expanding the use of these inputs. Gradually, technological innovations and mechanization of agriculture accelerated ...

U.S. Food Exports Under Various Worldwide Nutritional Constraints, Center For Agricultural And Rural Development, Iowa State University, Doeke C. Faber, Earl O. Heady Aug 1979

U.S. Food Exports Under Various Worldwide Nutritional Constraints, Center For Agricultural And Rural Development, Iowa State University, Doeke C. Faber, Earl O. Heady

CARD Reports

The world has become increasingly concerned with problems of health, population control, food production, and economic development. Organizations of the United Nations (Food and Agriculture Organization [FAO], International Labor Organization [ILO], World Health Organization [WHO], United Nations Economic Social and Cultural Organization [UNESCO], United Nations Development Program [UNDP]) have channeled a large amount of talent and finance into these areas in an attempt to improve conditions under which present and future generations live. Similarly, development organizations of individual nations and organizations such as the Rockefeller Foundation, the Ford Foundation, and the international research institutes also are making large contributions to ...


Final Report: Agricultural Sector Analysis In Thailand, Division Of Agricultural Economics, Ministry Of Agriculture And Cooperatives, Royal Thai Government, The Center For Agricultural And Rural Development, Iowa State University Jul 1979

Final Report: Agricultural Sector Analysis In Thailand, Division Of Agricultural Economics, Ministry Of Agriculture And Cooperatives, Royal Thai Government, The Center For Agricultural And Rural Development, Iowa State University

DAE-CARD Sector Analysis Series

The Agricultural Sector Analysis project in Thailand was initiated July 1, 1973,as a cooperative program between the Royal Thai Government and the United States Government. Royal Thai Government participation was provided by the Division of Agricultural Economics of the Ministry of Agricultural and Cooperatives with U.S. participation provided by Iowa State University. Funding for the project was furnished by the United States Agency for International Development and by the Royal Thai Government through the Department of Technical and Economic Cooperation. The project was funded initially for two years. It was subsequently extended to six years ending June 30 ...


Volume Of Grain And Fertilizer Requiring Transportation: Projections To 1984-1985 And 1989-1990 By Counties In Iowa, Center For Agricultural And Rural Development, Iowa State University, John J. Miller, C. Phillip Baumel, Robert N. Wisner, Thomas E. Fenton Jun 1979

Volume Of Grain And Fertilizer Requiring Transportation: Projections To 1984-1985 And 1989-1990 By Counties In Iowa, Center For Agricultural And Rural Development, Iowa State University, John J. Miller, C. Phillip Baumel, Robert N. Wisner, Thomas E. Fenton

CARD Reports

Iowa's grain and fertilizer transportation and distribution systems are undergoing major changes. Some rail lines are being upgraded; others are being abandoned. Major grain elevator expansions have been completed at some locations, and other grain and fertilizer facility expansions are being considered. Information on both the volume of grain likely to be moved out of Iowa counties and on the required in shipments of fertilizer in future years is needed to guide decisions on grain and fertilizer transportation and distribution facility expansion, relocation, or abandonment.


Weight Loss Of Fed Steers And Marketing-Decision Implications, Ronald Raikes, Gail M. Sieck, H. L. Self, M. Peter Hoffman Apr 1979

Weight Loss Of Fed Steers And Marketing-Decision Implications, Ronald Raikes, Gail M. Sieck, H. L. Self, M. Peter Hoffman

Special Report

Weight loss of fed steers during shipment to market adds to marketing cost. An understanding of factors influencing weight loss will aid feeders in making marketing decisions. In this study, we identified several factors that have a significant impact on percentage liveweight shrink and on hot-carcass weights of fed steers, quantified these impacts, and developed a method for predicting liveweight shrink and hot-carcass weight. Predictions of liveweight shrink and hot-carcass weight formed the basis for our development of guidelines for the evaluation and comparison of fed-steer marketing alternatives.


A Five-Commodity Econometric Simulation Model Of The U.S. Livestock And Poultry Sector, Center For Agricultural And Rural Development, Iowa State University, Roland K. Roberts, Earl O. Heady Mar 1979

A Five-Commodity Econometric Simulation Model Of The U.S. Livestock And Poultry Sector, Center For Agricultural And Rural Development, Iowa State University, Roland K. Roberts, Earl O. Heady

CARD Reports

Government grain policies of the early 1970s which returned U.S. agriculture to a free market situation are an example of the ignored condition of the livestock and poultry sector in policy formulation. An element of uncertainty not known for many years was reintroduced under the extreme fluctuations in grain prices in the free market. Feed prices began to increase as reserves of grains were depleted through high levels of exports. Not only were profit margins in livestock production reduced but also feed prices became highly volatile after many years of stabilizing government programs. The government no longer had vast ...


National Crop Model Of Thailand, Arthur L. Stoecker Mar 1979

National Crop Model Of Thailand, Arthur L. Stoecker

DAE-CARD Sector Analysis Series

The development of the national model of crop production in Thailand is the result of a joint effort by staff members of the Division of Agricultural Economics and by the Iowa State University team. This national model could not have been developed without the prior efforts of many individuals. Those efforts include previous assistance provided by the United States Agency for International Development in Thailand before the current project began. The leadership of Dr. Somnuk Sriplung. Director of the Division of Agricultural Economics in Thailand, has been a crucial element in the sector analysis project. The staff members of the ...
