COMPETITIVE ADVANTAGES OF POLISH ORGANIC SECTOR IN LIGHT OF CO-EXISTANCE BETWEEN GMO AND NON-GM PRODUCTS AgEcon
Maciejczak, Mariusz.
The perfect segregation of the different agricultural production types, namely conventional, organic or based on genetically modified organisms is not possible in practice. But the side by side functioning of this systems in agricultural production and further on of the products on the shelves requires suitable measures during cultivation, harvest, transport, storage, and processing to ensure co-existence. Consumers, food and feed industry, as well as wholesalers and retailers in European Union, including Polish ones demand a reasonable degree of choice between GMO and non-GMO derived products. Accordingly the ability to maintain different agricultural production and processing systems is a pre-requisite for providing a high degree of consumer choice. As...

Modelling Regional Agricultural Output Adjustments in Scotland in Response to CAP Reform AgEcon
Revoredo-Giha, Cesar; Leat, Philip M.K.; Milne, Catherine E..
The purpose of the paper is to present an agricultural supply model for Scotland used to estimate regional changes in agricultural outputs due to the 2003 Common Agricultural Policy (CAP) reform. Supply functions were estimated for several farm types based on generalised trans-logarithmic multiproduct cost functions (Caves, Christensen and Tretheway, 1981). The data used for the estimation were an unbalanced panel dataset constructed using farm level data from the Scottish Government’s Farm Accounts Scheme (FAS) survey. Using the estimated supply adjustments, individual farm level responses to subsidy and price changes were aggregated using agricultural census weights to estimate the output changes for different regions

Poorer performing paddock areas; do we:- Invest in amelioration, Vary input rates or Cull areas from the cropping system (IVC) AgEcon
Burt, Evan; Blake, John; McConnell, Graeme.
Poorer performing paddocks have plagued farmers often because paddocks tend to be treated as homogeneous when most are heterogeneous in the response to our current systems. The treatment of these paddocks requires that knowledge of where yield and quality differences are occurring. Differences in yield and quality necessitate a response action to occur to ensure that the management of these paddocks change. The purpose of zone management is to optimise the yield and quality of produce from the inputs applied to achieve high output/input ratios across the zones within the paddocks. The identification of performance differences in paddocks ensures that more efficient zone management practices can be applied to the paddock increasing the chances to profit....

POTENTIAL IMPACTS OF CHANGES TO GOVERNMENT PAYMENT LIMITS FOR MISSISSIPPI FARMS AgEcon
Miller, J. Corey; Coble, Keith H.; Vergara, Oscar; Broyles, Meredith E..
This paper examines the issue of government payment limits and how changes to these limits could impact program crops producers in Mississippi. Economic factors affecting the incidence of payment limits on various program crops are also discussed. The latest proposed change to payment limits, bill S. 667, is evaluated in contrast to the provisions of the current farm bill. Data from other states are also examined in order to obtain a better understanding of the regional differences in the application of payment limits.

Evaluating Yield Models for Crop Insurance Rating AgEcon
Lanoue, Christopher; Sherrick, Bruce J.; Woodard, Joshua D.; Paulson, Nicholas D..
Generated crop insurance rates depend critically on the distributional assumptions of the underlying crop yield loss model. Using farm level corn yield data from 1972-2008, we revisit the problem of examining in-sample goodness-of-fit measures across a set of flexible parametric, semi-parametric, and non-parametric distributions. Simulations are also conducted to investigate the out-of-sample efficiency properties of several competing distributions. The results indicate that more parameterized distributional forms fit the data better in-sample due to the fact that they have more parameters, but are generally less efficient out-of-sample–and in some cases more biased–than more parsimonious forms which also fit the data adequately, such as the Weibull. The...

Estimating the Carbon Footprint of Florida Orange Juice AgEcon
Spreen, Thomas H.; Dwivedi, Puneet; Goodrich-Schneider, Renee.
This study is a part of a comprehensive study which attempts to create a baseline of global warming impact (expressed in total greenhouse gas emission and measured in terms of carbon equivalent) associated with the production and consumption of a gallon of orange juice available in the form of NFC (Not from Concentrate) and FCOJ (Frozen Concentrated Orange Juice) in Florida. A detailed life‐cycle approach is adopted and greenhouse gas emissions of all the steps in the supply chain starting from citrus nursery management to the point where customer purchases juice from a food store are considered. This study reports total greenhouse gas emission related with the management of an acre orange grove under the two scenarios of with and without resetting of...

ALTERNATIVE MEASURES OF FARM SIZE: TRENDS AND DETERMINANTS AgEcon
Ahearn, Mary Clare; Yee, Jet.
Because of policy interest in the size distribution of farms, there is an interest in understanding the causes of changing farm sizes. This paper addresses an overlooked issue in the literature on the determinants of farm size, namely, the empirical specification of farm size. We examine 5 different size measures: acres operated, land and building value, cash receipts, cash receipts plus government payments, and a constructed measure of the rental value of farms. We graphically show the difference in trends in farm size using the various measures for the U.S. and selected states. We then discuss how the results of an analysis of the determinants of farm size depend on the farm size measure employed. The data set is a panel data set of 48 states from 1960...

IMPACTS OF POLICY REFORM ON SUSTAINABILITY OF HILL FARMING IN UK BY MEANS OF BIO-ECONOMIC MODELLING AgEcon
Acs, Szvetlana; Hanley, Nick; Dallimer, Martin; Robertson, Philip; Gaston, Kevin J.; Armsworth, Paul R..
Hill farming in UK is experiencing very difficult economic circumstances and many farmers rely on subsidies provided by the government for a large fraction of their income. The Peak District National Park is used as a case study to examine how farmers might respond to current policy changes � in particular, the move from area- and headage-based payments to the Single Farm Payment, and how optimal business plans should respond to these changes. The objective of this paper is thus to develop production models that predict how farmers will respond to changing policy framework conditions. For this purpose socio-economic surveys were carried out on 44 sample farms, in order to investigate how the land is managed on hill farms including ongoing policies and...

Host Country Attractiveness for CDM Non-Sink Projects AgEcon
Jung, Martina.
In the present study, CDM host countries are classified according to their attractiveness for CDM non-sink projects. A cluster analysis is conducted based on three different factors determining host country attractiveness (mitigation potential, institutional CDM capacity and general investment climate) in order to elaborate a CDM host country classification. The results suggest that only a small proportion of potential host countries will attract most of the CDM investment. The CDM (non-sink) stars are China, India, Brazil, Argentina, Mexico, South Africa, Indonesia and Thailand. They are followed by attractive countries like Costa Rica, Trinidad and Tobago, Mongolia, Panama, and Chile. While most of the promising CDM host countries are located in Latin...

Farm level effects of EU policy liberalization: Simulations based on an EU-wide agricultural sector model and a supply model of the German agricultural sector AgEcon
Deppermann, Andre; Grethe, Harald; Offermann, Frank.
The impact of sectoral or economy wide policy scenarios is often of strong political and public interest, yet it is a scientific challenge. When analyzing different levels of aggregation, the use of single models may not be sufficient. In this paper we establish an interface between the European Simulation Model (ESIM) and the Farm Modelling Information System (FARMIS). The linkage of the two models allows us to quantify adjustment processes both at the sectoral level and at the farm group level for the German agricultural sector. Different liberalization scenarios are presented and compared to a reference scenario. The abolishment of market price support leads to a reduction of farm incomes, especially if direct payments are also reduced. The low absolute...

SMALL HOLDERS, TRANSGENIC VARIETIES, AND PRODUCTION EFFICIENCY: THE CASE OF COTTON FARMERS IN CHINA AgEcon
Huang, Jikun; Hu, Ruifa; Rozelle, Scott; Qiao, Fangbin; Pray, Carl E..
The overall goal of this study is to measure the effect of the impact that genetically modified cotton varieties have had on the production efficiency of small holders in farming communities in China. We also find that the adoption of Bt cotton varieties leads to a significant decrease in the use of pesticides. Hence, we demonstrate that Bt cotton appears to be an agricultural technology that improves both production efficiency and the environment. In terms of policies, our findings suggest that the government should investigate whether or not they should make additional investments to spread Bt to other cotton regions and to other crops.

RISK MANAGEMENT THROUGH ENTERPRISE DIVERSIFICATION: A FARM-LEVEL ANALYSIS AgEcon
Mishra, Ashok K.; El-Osta, Hisham S..
Enterprise diversification is a self-insuring strategy used by farmers to protect against risk. This paper examines the impact of various farm, operator, and household characteristics on the level of on-farm diversification. Results provide evidence that larger farms are more specialized. Also, farmers who participate in off-farm income and farms located near urban areas are less likely to diversify. Additionally, results also show a significant positive relationship between diversification and farm/crop insurance and sole proprietorships. Finally, there is also evidence that farms that received government payments are more diversified than their counterparts.

Farming Options for Ameliorating Acidifying Soils in South - Eastern Australia: An Economic Assessment. AgEcon
Islam, Q.; Mullen, John D.; Brennan, John P.; Li, G.D.; Helyar, K.R.; Jones, Randall E..
Acid and acidifying soils occur extensively in Australia. Currently, some 90 million hectares of agricultural land in Australia is considered to be acidic and around 35 million hectares are considered to be highly acidic which is both a serious agricultural and environmental problem. The nature, impact, and causes of soil acidification vary across Australia, as do farming systems and the institutional and socioeconomic issues relating to land management. In high-rainfall areas of south-eastern Australia, managing acid soils is particularly difficult in permanent pasture systems. In this paper, an economic analysis is made of the results of a long-term trial (MASTER – Managing Acid Soils Through Efficient Rotations) aimed at developing a sustainable...

Agricultural Profits and Farm Household Wealth: A Farm-level Analysis Using Repeated Cross Sections AgEcon
Blank, Steven C.; Erickson, Kenneth W.; Nehring, Richard F.; Hallahan, Charles B..
This study examines the relationship between agricultural profits and farm household wealth across locations and farm sizes in U.S. agriculture. A multiperiod household model is used to develop hypotheses for testing. Results indicate that farmland has out-performed nonfarm investments over the past decade. Thus, households may want to keep their farmland to build wealth, even if it requires them to earn off-farm income. The analysis implies that decision will be made based on farm household wealth factors having little to do with agriculture.
