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,... |

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.... |

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... |

One of the most studied systems in the last 20 years. The lactoperoxidase-thiocyanate-hydrogen peroxide system (LP System) is due to its potential possibilities to avoid raw milk deterioration against undesirable microorganisms. There are experimental and practical evidences demonstrating that the use of this method is innocuous. That is why, the Committee of Experts for Food Additives (JECFA) has pointed out that it is acceptable from the toxicological point of view. However, CODEX guidelines have identified the need of having greater information about the risk of exacerbation of pathogen bacteria present in milk because of the inhibition of the natural flora present in raw milk. The objective of the present study consisted on evaluating the effect of the... |

A methodology for the territorial risk analysis of biological disasters due to transboundary animal diseases (TADs) was developed and conducted in all municipalities in the country. The methodology identifies the relevant places for the potential entry and the following spreading of TADs (objectives with biological risk-OBR), and characterizes the level of their vulnerability (sanitary gaps) as well as that of the local animal populations. The vulnerability of animal populations considers many topics divided into four aspects: structure of animal production, sanitary control, urbanization of animal rearing, and general characteristics of the municipality. In 161 municipalities, 1597 OBRs were identified. Few municipalities were classified at the highest... |

This paper presents the practical application of concepts, and some methods of risk analysis, to check the possibility of overcoming a water level of project in the spillway of dam Orós, by excess of influent flow. Also evaluated the empirical formulas contained in the original design. Due to the difficulty of obtaining design data from the dam, since the end of construction date of January, 11, 1961, we minimize the effects of some variables in the calculations, leading us to the consequent simplification of the scenario under study. For a better evaluation and characterization of the setting, some variables in the model such as water level, accumulation and flow of the spillway, had updated their data to June 28, 2011. We have demonstrated the importance... |

Risk in the agricultural sector has multiple dimensions or factors and prioritization of these can support decision making. On the other hand, knowing the importance of these risk factors for distinct agricultural activities and how they vary according to geographic zone constitutes relevant information for agricultural development. The objective of this study was to prioritize risk factors that are highly relevant for farmers in Central South Chile. The multi-criteria Analytical Hierarchical Process (AHP) methodology was used to define a decision structure with four risk factors or criteria: climate, price and direct cost variability, human factor, and commercialization. In general, results obtained showed that there are no important imbalances in the... |

The joint analysis of indicators of the investment project is very relevant in making decisions, resulting in more consistent information regarding risk assessment and its confrontation with the possibility of return. This research aimed to evaluate the economic feasibility of Red Angus young steers finished in feedlot, slaughtered at 340, 373, 396 or 430kg with use of various financial indicators, marketed with or without bonus. The purchase of feeder cattle and feeding were variable costs with a higher share in the total cost. In the analysis with bonus, the regression analysis to gross margin, net margin, net present value, benefit:cost index and additional return on investment showed quadratic behavior, with the point of maximum at 406kg (R$ 185.17),... |
