Agriculture and aquaculture have common features associated with their biological nature affecting risk exposure of the businesses. The aim of this paper is to compare risk exposure in salmon farming and agricultural enterprises in Norway by using an implicit error component model to examine the risk structure of yields, prices and economic returns at the farm level. Results indicate a higher farm-level year-to-year variability in yields, prices and economic returns in salmon farming than in agricultural enterprises. The variability in livestock enterprises was generally lower than for crop enterprises. Return on assets was highest in salmon farming with an average annual return of 9.2%. All of the agricultural farm types exhibited a negative average... |

To lower the incidence of human food-borne disease, experts and stakeholders have urged the development of a science- and risk-based management system in which food-borne hazards are analyzed and prioritized. A literature review shows that most approaches to risk prioritization developed to date are based on measures of health outcomes and do not systematically account for other factors that may be important to decision making. The Multi-Factorial Risk Prioritization Framework developed here considers four factors that may be important to risk managers: public health, consumer risk perceptions and acceptance, market-level impacts, and social sensitivity. The framework is based on the systematic organization and analysis of data on these multiple factors.... |

Developed for carrying out risk assessments under the European Commission (EC) Council Regulation No 708/2007 concerning the use of alien and locally absent species in aquaculture (ASR), the European Non-native Species in Aquaculture Risk Assessment Scheme (ENSARS) is briefly summarised, and the ‘Organism’ module is applied to the 24 species listed in ASR's Annex IV. Four other ENSARS modules (Infectious Agent, Facility, Pathway, and Socio-economic) were used to assess two case study species (European catfish Silurus glanis L. and red swamp crayfish Procambarus clarkii Girard). No Annex IV species was categorised as low risk, 10 as moderately low risk, 12 as medium risk, two as moderately high risk and none as high risk. The results are discussed and... |

Mathematical programming methods are widely used for modelling farmers' decision-making and for economic analysis in agriculture. In this study, a MOTAD risk-programming model is applied to study the effects of risk on cropping pattern and farmers' income in Ramjerd and Sarpaniran districts near Marvdasht in the Fars Province of Iran. Primary data from 194 farmers randomly selected from 31 villages are used in this study. The results indicate that variability of crops gross margins or outcomes has a significant effect on cropping pattern but it varies over different farmers and regions with various conditions. Moreover, it was found that farm plans with more number of crops have a lower return but high degree of certainty. Based on this research,... |

Recent major spills on European coasts have highlighted the primary policy relevance for the EU of oil spills. This paper assesses the risks related to carrying oil to the EU along the route from the Russian Black Sea coast to Sicily, Italy (one of the most congested and strategically relevant European import routes). We develop a methodology based on Fault Tree Analysis, and we apply it to the most likely causes of an oil spill. We couple the resulting probabilities with data on expected spill size, types of oil carried and cleanup costs, to estimate expected costs for cleanup and loss of cargo. The route analysed appears to be a risky one; there is a high to very high risk of a spill along this route. The Turkish Straits turn out to be the major... |

ABSTRACT We aimed to study the potential use of carcass condemnation data of broiler chicken slaughterhouses in Brazil as indicators in an animal welfare monitoring program, and to identify points to be addressed to increase data reliability. Data from 2010 to 2015 in the states of Paraná (PR), Santa Catarina (SC) and Rio Grande do Sul (RS) were used. Fractures and bruising were recorded together, representing the most prevalent welfare problem, followed by skin lesion or inflammation. In PR, progressive increases on injury, arthritis, ineffective bleeding, and air sacculitis condemnation may reveal important welfare aspects. High correlation between AWI within PR was more commonly observed than in RS and SC, perhaps as a result of earlier implementation... |

Se ubicaron 29 poblaciones naturales de Pseudotsuga menziesii en Hidalgo, Tlaxcala y Puebla, con un estimado de 9,029 árboles adultos, en 682 ha que se ubican desde 2,450 a 3,400 m s.n.m. Las localidades son de clima templado, con temperatura media anual de 10.1 a 14.0 °C y precipitación de 611 a 1,109 mm anuales. Pseudotsuga convive con Abies religiosa y varias especies de Pinus y Quercus, en exposiciones N, NO y NE. Los suelos son de pH ligeramente ácidos, ricos en materia orgánica y clase textural franco-arenosa o franca. El tamaño poblacional varía de 4 a 1,450 árboles maduros; 11 de éstas menos de 100 individuos adultos, con poca repoblación natural en todas ellas. Existe gran fragmentación en su distribución natural. Con base en un análisis de... |
