Soil Depletion And Water Quality: A Case Study In The Conjunctive Management Of Natural Resources , James Samuel Shortle Jan 1981

Soil Depletion And Water Quality: A Case Study In The Conjunctive Management Of Natural Resources , James Samuel Shortle

Retrospective Theses and Dissertations

Conceptual models of crop production are developed to demonstrate the applicability of the theory of natural resource extraction to the economic analysis of cropland erosion and to draw upon this theory and the theory of environmental quality to consider economic issues in cropland erosion and erosion control for water quality improvement. Based upon the conceptual analysis, a multi-period model of cropland production in a small Iowa watershed is developed to consider these same issues quantitatively. The results demonstrate the importance of dynamic analysis in the investigation of issues in cropland erosion control and provide an economic basis for choosing alternative ...

Long-Term Impacts Of Soil Erosion: A National And Interregional Analysis For The Year 2030 , Burton Clyde English

Retrospective Theses and Dissertations

There has been a growing concern over soil erosion in recent years. Farmers, government officials, agronomists, agricultural economists, and the general public have become concerned with growing rates and the extent of soil loss under the "all out" production of recent years. Soil erosion cannot be entirely arrested economically or even physically. This study examines the impacts that would be likely if attempts are made to arrest erosion;The linear programming model used in the analysis is national in nature, incorporating 28 market regions and 105 producing areas and is used to examine five solutions for 2030. The Base is ...

Capital And Credit Demands In U.S. Agriculture: Projections For Alternative Economic And Policy Environments , Mark Richard Drabenstott

Retrospective Theses and Dissertations

Capital and credit demands in U.S. agriculture are projected for alternative policy and economic environments. The primary objective is to incorporate a finance sector in a sequential, econometric simulation model of U.S. agricultural production. Capital and credit demands are projected for the period, 1980-2000. The simulation model used is maintained by the Center for Agricultural and Rural Development. Structural equations in the finance sector estimate annual capital flow demands for real estate, buildings and land improvements, machinery, commodity inventories, livestock inventories, and financial assets. The model estimates annual net farm income. Given total capital demand and income estimates ...

The Bolivian Beef Cattle Industry: Effects Of Transportation Projects Upon Plant Location And Product Flows In Beni , Luis A. Ampuero-Ramos Jan 1981

The Bolivian Beef Cattle Industry: Effects Of Transportation Projects Upon Plant Location And Product Flows In Beni , Luis A. Ampuero-Ramos

Retrospective Theses and Dissertations

Bolivia has the potential to become an important beef exporting country in South America. However, to penetrate foreign markets (in Chile, Peru, and Brazil) she must upgrade her processing facilities. This calls for the construction of new slaughterhouses.;In the course of the 1980s, several new transport linkages (involving roads, railways, and waterways) are to be completed as Bolivians seek to integrate their territory. Most of these new linkages will connect the department of Beni, in the tropical lowland, with the rest of the country. It is in Beni where the greatest potential for cattle-beef production exists.;This study seeks ...

Supply Analysis Of Important Crops In Thailand , Apichart Pongsrihadulchai

Retrospective Theses and Dissertations

The purpose of this study is to attempt to contribute to the knowledge of the influence of price on the supply of agricultural production in Thailand. Seventy-two provinces in the country have been grouped into nineteen agroeconomic zones. Each zone is considered to be homogeneous in terms of climatic, agronomic conditions, and agricultural activities. The statistical analysis in this study is primarily at the zone level of aggregation. However, a national aggregate model is also estimated. The period under study is from 1969 through 1977 and the crops included are rice, corn, cassava, sugarcane, and kenaf.;The Nerlovian supply function ...


Modeling The Japanese Feed Grain Market , Wisut Wangworawut Jan 1981

Modeling The Japanese Feed Grain Market , Wisut Wangworawut

Retrospective Theses and Dissertations

This study develops two Japanese feed grains importation models. Model I considers only the Japanese market and consists of five different sub-models; the feed grain and oil seed imports, the commercial mixed-feed market, the processed food products market, the livestock products market, and the sources of feed-grain imports. This study also tries to capture Japanese policies on reducing rice stock surpluses by stimulating rice use in mixed-feeds, and diversifying the source of feed grain imports;There are 39 endogenous variables in Model I. The thirty-nine structural equations consist of: thirty estimated equations, 3 identity equations, and 6 market-clearing conditions. The ...


Econometric Analysis Of Farm Machinery Investment And Simulations Under Alternative Energy, Price Support, And Export Policies , Kisan Ramachandra Gunjal Jan 1981

Econometric Analysis Of Farm Machinery Investment And Simulations Under Alternative Energy, Price Support, And Export Policies , Kisan Ramachandra Gunjal

Retrospective Theses and Dissertations

The historical trends in structure, extent, and intensity of agricultural mechanization are analyzed in this study. The numbers of tractors, grain combines, corn pickers and picker shellers, pickup balers, and field forage harvesters peaked during the early 1960s. The decline in their numbers after the '60s is brought about mainly by the qualitative changes in those machines. The total tractor horsepower on farms also increased over the period 1963-79. Analysis of measures such as acres per horsepower, number of tractors and combines per farm, and acres per tractor and combine indicates that the intensity of machinery-use has increased over the ...

Macroeconometric Model Of The Thai Economy , Kajonwan P. Itharattana

Retrospective Theses and Dissertations

Thailand is an agricultural country in Southeast Asia. She always faces the same problems as other developing countries, such as high growth rate of population, low income per capita, unequal income distribution, and low productivity of labor. Thus, government attempts to solve these problems through the national development planning. The first national development planning was adopted in 1960. It did not achieve as expected due to lack of good statistical data and trained manpower. The Ministry of Agriculture and Cooperatives was assigned to make a plan for agriculture. In 1973, there was a joint project between the Ministry of Agriculture ...
