MEETING THE KYOTO TARGET THROUGH CONSERVATION TILLAGE AND ITS IMPLICATION FOR NATURAL CAPITAL MAINTENANCE, PRODUCTION EFFICIENCY, AND SUSTAINABILITY
According to Article 3.4 of the Kyoto Protocol, agricultural soil could be used as a sink for carbon sequestration and hence it may provide an alternative venue to sequester the greenhouse gas emission. US plans to reduce the carbon emission amount by seven percent below the 1990 level within the target date of 2008-2012. The major approaches to achieve the goal targeted by Kyoto Protocol in US are through fossil fuel tax and increasing forest area by afforestation. This means fossil fuel price will increase which will have a direct impact to conventional tillage cost. As a result farmers would be motivated to use less machinery operation in farming and hence may use conservation tillage in farming practices. Rather than cause and effect relationship created by fuel price increase, conservation tillage itself has been considered as a method suggested to increase carbon sequestration. We analyze the economic and environmental roles of conservation tillage in carbon sequestration. The use of conservation tillage helps to sequester carbon in the form of soil organic matter. We examined the potential of conservation tillage in sequestering carbon and its role in increasing soil natural capital and thus the productivity of soil. We then used the concept of production efficiency to calculate the benefits of soil carbon sequestration using sustainability criteria. The detail of carbon sequestration and soil natural capital buildup were demonstrated using conservation tillage practiced in cotton production in Georgia. Four systems of conservation tillage encompassing both chemical and organic source of plant nutrients were compared for their capacity to sequester carbon. Organic matter buildups were faster in a system with conservation tillage and organic sources of nutrient compared to conventional tillage. Result indicated that in a system with a slow buildup of natural capital, production efficiency was not significant. This has resulted the system to be unprofitable in the short run and unsustainable in the long run. The system with a high amount of organic matter increases the production efficiency of applied inputs and also plays an important role in substituting chemical fertilizers. Alternative tillage management systems were evaluated for their sustainability using total factor productivity. It was found that conservation tillage meets criteria of sustainability more often than the management system containing conventional tillage. Conservation tillage was found to be the best alternative not only to sequester carbon but also developing natural capital-based sustainable system.Kyoto protocol, Carbon sequestration, Natural capital, Production efficiency, Sustainability, Environmental Economics and Policy, Productivity Analysis,
Factors Affecting the Decision to Adopt and Continue Best Management Practices by Broiler Producers
We analyzed survey data collected from broiler producers in Louisiana to understand the factors affecting the longevity of best management practices adoption. Results indicated variables such as future expansion potential and the length of time the farm have been with the family decreases the chance of adopting best management practices. Our results support the idea that education and income would have positive results on the entry decision to adopt best management practices.adoption, best management practices, broiler production, entry, exit, Farm Management, Livestock Production/Industries,
ECONOMIC EFFECT OF IMPERFECT INFORMATION ON CONSERVATION DECISIONS
Cotton farmers in the Piedmont region incorrectly believe conservation systems with winter cover crop and no-till cultivation yield less than conventional systems. We model the effect of organic matter on productivity and show how ignoring this effect causes returns to be underestimated. Farmers with imperfect information underinvest in residue management.residue management, organic matter, productivity, comparative statics, Farm Management, Land Economics/Use, Productivity Analysis,
PRODUCTION TERMINATION AS AN ALTERNATIVE TO MITIGATE NUTRIENT POLLUTION
Nutrient runoff from agricultural land can be reduced through production termination to mitigate water pollution. The willingness to accept value to terminate the broiler production is evaluated using sample selection model. The result showed a positive relationship between the decision to participation and stated WTA value indicating the producers are willing to terminate the production but at high cost. The farmer’s perception about government role on water pollution, farm income, information and awareness about other pollution reduction alternatives play a major role on stated WTA amount as well as on participation decision.Environmental Economics and Policy,
PART TIME FARMING, FARM PRODUCTIVITY, AND FARM INCOME: EVIDENCE FROM THE SOUTHEAST US
We analyzed the effect of part time farming in the US using a panel data analysis method. Data from three census years on ten southern states and the counties therein indicated that part time farming has a positive impact on the total value of the farm products produced. Although the result is preliminary, it sheds an important light on the changing farm structure in the USA.Agricultural Finance,
DYNAMIC ECONOMIC ANALYSIS OF A RESIDUE MANAGEMENT SYSTEM IN COTTON
Residue management system (RMS), comprised of no till cultivation, a winter cover crop, and poultry litter, could be an alternative to existing management system in cotton production in the Georgian Piedmont. We compare the productivity and profitability of RMS with the current system over time, focusing on the role of organic matter. Using dynamic bioeconomic modelling technique, we show that the net return and land value difference between these two systems increase as the terminal period increases. We conclude that if financial and capital markets based on organic matter work efficiently, farmers will choose RMS in cotton production.residue management, organic matter, productivity, Crop Production/Industries,
FROM THE PERSPECTIVE OF GLOBAL WARMING: ALTERNATIVE FARMING SYSTEMS AND SUSTAINABILITY
According to Article 3.4 of the Kyoto Protocol, agricultural soil could be used as a sink for carbon sequestration. Soil sequestration of carbon provides dual benefits: an increase in soil productivity and a reduction in atmospheric carbon concentration. The gain in soil productivity is a slow process and attaining a steady-state level of carbon in soil takes several years. A frequently encountered difficulty in this situation is how to discount the future benefit of carbon sequestration into a current term. We compared the net benefit of four alternative management systems using discount rates based on the sliding gamma distribution, market rate of investment, and the social rate of time preference. We also calculated the sustainability of these alternate management systems based on the profitability and productivity index and their capacity to maintain the natural capital in soil. The result indicated that a management system that combines no-till and an organic source of nutrients is the most attractive system based on carbon sequestration, total discounted net present value, and sustainability perspectives.carbon sequestration, conservation practices, strong and weak sustainability, discounting method, Environmental Economics and Policy, Production Economics,
DYNAMIC ANALYSIS OF A RESIDUE MANAGEMENT SYSTEM IN COTTON
Residue management system (RMS) offers increase productivity gain to farmers by increasing the organic matter. Farmers have failed to realize this gain and consequently have not adopted RMS in cotton cultivation. Benefit of adopting RMS system appears sooner than farmers would think.Environmental Economics and Policy, Productivity Analysis,
NUMERAIRE CHOICE IN AGRICULTURAL SUPPLY ANALYSIS
Economic theory provides little guidance for selecting a numeraire in estimating dual function profit functions. In this study, we examine the choice of numeraire price (equation) for profit function models of Iowa agriculture. The choice of numeraire is evaluated by forecasting accuracy and with a non-nested specification test.Research Methods/ Statistical Methods,
Policy Reform and Off-farm Labor Supply by Operators in the Delta Region: A
Off-farm employment has been an integral part of the emerging structure of production agriculture in the South. Government farm program payments, farm structure, and strong non-farm economy have important impact on labor allocation, farm and non-farm labor, decision of farm operators. The objective of this investigation was to evaluate the determinants of off-farm labor supply for farm operators in the Delta States. Results show that off-farm work, educational level, presence of teenager, and farm tenure positive and significant impact on ff-farm labor supply by farm operators. On the other hand, farm size, household wealth, decoupled and couple farm program payments, and degree of farm diversification have a negative and significant impact on off-farm labor supply by farm operators. the semiparametreic functional formulation of the farm size and household wealth variables were found to perform better than the linear functional form.Off-farm labor supply, Delta region, Tobit, semiparametric, government farm program payments, education, Farm Management, Labor and Human Capital,
