| The purpose of this paper is to assess the opportunity returns forgone to cotton producers in the lower Mid-South region of the United States for growing cotton, compared to alternative commodities. We calculate the actual net returns per acre for selected cotton-producing counties in Arkansas, Louisiana, and Mississippi. In addition, we calculate the opportunity returns per acre if the acres planted in cotton were planted in the highest net return commodity per acre between corn and soybeans during the period 1997 through 2008. Our results find that producers in these cotton producing-counties faced sizeable opportunity revenues foregone averaging 43% between 2003 and 2008. Most observers of the cotton industry would argue that these foregone revenues are... |

| The WWW, along with email, are simple forms of information technology which have become easily accessible through the Internet. They offer great sources of up-to-date information and data-sets of all kinds. They allow you to get in contact, communicate and exchange information in electronic form. Of particular interest are the increasing number of web sites which pertain to agriculture and notably to markets. You may find quotes on futures within 10 minutes of their actual calls, and you may also find outlook reports on specific commodities for the years to come. This paper serves as a guide to these different sources on market information presently available on the Internet1. These sources may be daily, weekly, monthly or yearly reports, outlook reports,... |

| The goal of this paper is to increase the capacity of the agriculture sector to understand and respond to the climate variability, by reducing the uncertainty of the farmers over decisions that are affected for meteorological conditions. To study the yield responses to meteorological variables in the past is crucial to understand the vulnerability of the agriculture to the climate change in the future. We have estimated regression models where the historical yields have been put in dependence of variables that can represent main drivers of global change, such as climate variables and technological ones. In this context we evaluate its influence over the yields. Among the conclusions we find that the adaptation to climate change requires challenges in which... |

| This study quantified interactions between animal welfare and farm profitability in British extensive sheep farming systems. Qualitative welfare assessment methodology was used to assess welfare from the animal's perspective in 20 commercial extensive sheep farms and to estimate labour demand for welfare, based on the assessed welfare scores using data collected from farm inventories. The estimated labour demand was then used as a coefficient in a linear program based model to establish the gross margin maximising farm management strategy for given farm situations, subject to constraints that reflected current resource limitations including labour supply. Regression analysis showed a significant relationship between the qualitative welfare assessment... |

| This paper analyses the evolution of agriculture’s participation in the US gross domestic product (GDP) from 1960 to 2001. An econometric model is run in order to identify the main variables that determine this participation. From 1960 to 2001, there is a downward trend of agriculture’s participation in the US GDP with a break from 1971 to 1973, in other words, agriculture’s participation in the US GDP decreased from 1960 to 1970, increased from 1971 to 1973 and decreased again from 1973 to 2001. The 1971-1973´s break in the downward trend of agriculture’s participation is econometrically proved. Dataset organized in graphs show grain and meat production steadily enlarged from 1970 to 2001, what is closely related to the productivity increase and federal... |

| Using conjoint analysis methodology, this study used an online survey to measure consumers’ preferences for the apple attributes as place of production, method of production, and price. The results of the conjoint analysis indicate that consumers are willing to make trade offs between the studied attributes. Segment analysis indicates Place-oriented consumers may be willing to pay 60% to 70% premiums for locally grown apples. The high consumer preferences for locally grown products combined with environmental benefits transferred through genetic modification provide an opportunity for producers to capture and build their markets, especially within certain market segments. |

| Swidden being a widespread form of land use in the tropics comprehensively defining it become a difficult task. Its characteristics embrace different types of topography, demographic feature, ethnic and ecological diversities. It also varies in terms of cropping pattern, frequency of land use, tools and methods of practice. It is argued that the institutions governing swidden are static in nature and do not adapt to the requirements of the changing ecological and social needs. This necessitates understanding what characterise institutions in a traditional swiddening society, and hence, changes in these characteristics to appreciate whether swidden is a static form of agriculture or changing over the time and space. There are a few aspects, which underscore... |

| This poster proposes a new procedure in agriculture supply modelling by the positive mathematical programming (PMP) approach. This approach is now widely used in last CAP reform simulations. However, simulation behaviour and performances of PMP procedures depend of the way parameters of the non linear total cost function in the objective function are recovered. We propose a new specification of the total cost function where land is explicitly considered as a fixed input. By using relative parts of land of the different activities this new PMP procedure permits to better capture production behaviour when economic conditions. It also permits to avoid a drawback of the early procedures concerning marginal activities |
