Ecologists recognize that fire and herbivory are essential to maintaining habitat quality in grassland ecosystems. Prescribed fire and grazing are typically used on public reserves to increase biodiversity, improve grassland productivity, and control encroachment of woody plants. However, these tools, particularly prescribed fire, have not been widely adopted by private landowners. Fire suppression and prescribed fire are strategies that present competing risks to owners who make management decisions. We explore landowner perceptions of risk associated with (1) eastern redcedar (Juniperus virginiana) encroachment, and (2) the use of prescribed fire to control woody species in the Grand River Grasslands of Iowa and Missouri, USA. We found that although... |

An online survey was conducted to describe stakeholders' perceptions, attitudes and practices towards risk prevention in the food chain and to explore if common features could be extracted from different fields of competency or groups of stakeholders. Out of 80 participants, 60% believed that pathogenic microorganisms were the main hazard to prevent. Twenty-four percent perceived climate change as the main risk factor. Seventy-three percent believed that hazards in the food chain are preventable and they often showed a positive attitude towards risk prevention measures. The opinion of 75% of stakeholders was that prevention measures should be compulsory and under the shared responsibility of both food business operators and competent authority.... |

Since the first case of bovine spongiform encephalopathy (BSE) was encountered in Japan in 2001, the country quickly responded with a change from passive to active surveillance. The response has not been a smooth one, though, and news media have contributed to opening the public’s eyes to inadequate behavior from government sources responsible for monitoring and protecting the health of consumers. The resultant information“gap” has served to augment the typical Japanese perceptions of risk assessment, as assessed in surveys from 2003 to 2005. Such false beliefs have caused consumers to call for 100% testing of animals for BSE despite accepted scientific standards which do not support such comprehensive and costly surveillance. Instead, testing agencies... |

A highly pathogenic H5N1 strain of avian influenza (AI) has been confirmed in 420 human cases and has caused 257 deaths in the world starting from 2003. Using face-to-face interviews, our data were collected by utilizing a stratified sampling scheme following the distribution of gender and age in three major metropolitan areas in Taiwan, including Taipei, Taichung, and Kaohsiung. The questionnaire was designed to retrieve information including AI knowledge, risk perceptions, and behavioral changes of two types of consumers, primary shoppers and general consumers. In total, 501 primary shoppers and 505 general consumers completed the survey in June 2007 and were recorded for analysis. The empirical results show several interesting findings, especially, that... |

Food safety crises usually receive widespread publicity and an extensive media coverage which evidently is mainly negative. Based on previous research, the purpose of this article is to illustrate the impact of positive and negative food safety information on demand both in the short and long term. Apparently, asymmetric effects of media coverage provoke a shift in the consumers' perception of risk and, in a subsequent step, their reactions. This cycle shall be investigated and explained in detail since it improves the prospects for a prediction of consumers' reactions to food safety crises. Results will contribute to the European Commission's research project Food Risk Communication and Consumers' Trust in the Food Supply Chain - TRUST. |

The local, regional and global economic and natural phenomena of previous decades collectively emphasize the growing importance of risk factors affecting agricultural production both directly and indirectly. Agricultural producers should not restrict their risk management strategies to offset and relieve the problems caused by climatic and natural phenomena, but the knowledge of up-to-date professional, market, and agricultural policy developments is more and more an indispensable condition of successful farming. Besides what mentioned above, it is at least equally important to answer the question of how farmers perceive the importance of risk factors surrounding their activities, as it strongly influences the shaping of their risk management strategies.... |

This study analyses the specific risks that organic farmers must manage. Due to the special features of management of their productive system, and due to the specific characteristics of their cultivations, they must face different risks than conventional farmers. Even if the Spanish farmers rely on the insurance system to manage their risks, today organic farmers do not have specific insurance products to manage them. The methodology and results presented in this study include the following: First, the primary information is compiled after the elaboration of more than 500 questionnaires to organic farmers of diverse Spanish regions. Second, the risk analysis is carried out by evaluating statistical, probabilistic, and stochastic properties of the... |
