Our knowledge on the biology and ecology of marine species have improved greatly through the use of archival tags by enabling the collection on information from individual in the wild. This is specifically true for large pelagic species such as the Atlantic Bluefin tuna (ABFT, Thunnus thynnus) where, for the first time, it has been possible to confirm through fisheries-independent data, migration patterns, reproductive and feeding behaviours and habitat use. However, large-scale tagging experiments that would enable researchers to tackle group behaviour are difficult to set up. On the one hand, the impact of the actual tagging operation should be as minimal as possible to avoid any change in behaviour of the fish which could influence tag data analyses. On... |

Rural broadband infrastructure and service has received a significant amount of funding through the American Recovery and Reinvestment Act of 2009. These funds should increase broadband availability, but will broadband be used in rural areas and in particular by farmers? This paper uses Agricultural Resource Management Survey data to investigate why the majority of U.S. farmers choose not to use the Internet in their farm business. Although frequently cited by policymakers, concerns about inadequate Internet service or security actually account for a small percentage of responses. This research identifies targeted educational programs that focus on alleviating perceived barriers to Internet use. |

Even though farming accounts for only about 1 percent of the total national workforce, it is at the core of the food and fiber system. The system is one of the largest sectors in the U.S. economy, and is comprised of industries related to farming, including feed, seed, fertilizer, machinery, food processing, manufacturing, and exporting. The interrelationships among the sectors of the food and fiber system and the U.S. and world economies are many and complex. As a result, U.S. and world policies and economic factors--such as interest and inflation rates--play a critical role in everything from the cost and availability of farm credit to the demand for farm products at home and abroad. The farm crisis of the 1980's illustrates how specific economic events... |

The harvest with raw cane is increasingly present in the system of production of sugar cane in Brazil. From the decade of 90, precisely in the year 1997, the sucroalcooleira agribusiness in the state of Sao Paulo, the main centre Brazilian producer, stated adapt its system of harvesting of cane without burning prior to meet environmental Rio Branco – Acre, 20 a 23 de julho de 2008 Sociedade Brasileira de Economia, Administração e Sociologia Rural restrictions. This paper presents the current time the culture of sugar cane for the collection of raw cane and the cane burning in the region of the forest north of Pernambuco The focus of this work was to analyze the strategies of crops used by the main companies sucroalcooleiras the region. |

We designed a field experiment involving real payments to elicit farmers’ risk preferences. Farmers are a very interesting sample to study since risk has always played an important role in agricultural producers’ decisions. Besides, European farmers may face more risky situations in the future. In this context, it is very important for any economic analysis focusing on agriculture to correctly assess farmers’ behaviour in the face of different sources of risk. We test for two descriptions of farmers’ behaviour: expected utility and cumulative prospect theory. We use two elicitation methods based on the procedures of Holt and Laury (2002) and Tanaka et al. (2010) on a sample of 30 French farmers. The experiment consists in asking subjects to make series of... |

More research is needed before we know the implications of climate change for Australian farms. Nevertheless given the information at hand, an assessment can be made of some early indicators. First, the severity of the recent drought was compared with earlier droughts. Second, the trend in rainfall was examined. Third, projections of climate change were reviewed to assess the likely course of climate variability, and hence provide a picture of the severity of future droughts. Although further research is warranted, the indications are that even if rainfall is no lower in future droughts, they may seem more severe because rising temperatures will tend to increase evaporation and reduce runoff. |

Because land is scarce, farmers in China increasingly have to rely on nonfarm activities to enhance their incomes. The functioning of rural nonfarm labor markets is therefore crucial in determining who has access to nonfarm employment. Previous studies have identified human capital as a key factor determining the selection of workers in the rural nonfarm economy. Using a detailed household survey of northern and northeastern China, this paper shows that guanxi (social networks), has also played an important role. With limited nonfarm job opportunities and poor market information, farmers with better social contacts are more likely to obtain nonfarm jobs. Moreover, guanxi has a larger effect on the nonfarm employment opportunities of male workers than... |
