| We report results of an analysis of the attribution of relative responsibility across the stages of the food chain for ensuring food safety. Specifically, we identify perceptions of the share of the overall responsibility that each stage in the food chain has to ensure that the meat people cook and eat at home does not cause them to become ill. Results are reported for two groups of stakeholders: consumers and farmers, and for two types of meat: chicken and beef. The stakeholders’ opinions regarding the relative degrees of responsibility of the sequential food chain stages (feed supplier, farmer, livestock transportation, abattoir,… consumer) are elicited via surveys using the Maximum Difference technique (best-worst scaling). The data are analyzed using... |

| Increasing public interest in the concept of sustainable agriculture has resulted in the development of a number of methods that could be used for the assessment of sustainability of various agricultural production systems. Because of its complex, multi-dimensional nature, sustainability is most often assessed using numerous indicators, which make aggregate comparisons among systems difficult. In this paper we propose a methodology that could be beneficial in aggregate sustainability assessment. We apply conjoint analysis to identify economic, social, and ecological attributes that are perceived as important for agricultural sustainability by different stakeholders and to assess their relative impact on the overall sustainability measure. |

| In order to guide conservation and restoration of wildlife in agricultural areas research is needed into the trade-off between wildlife and agricultural production and income. This study presents a location specific model for optimizing wildlife management on crop farms using the integer programming technique. Available data and indicators of wildlife production are presented. Furthermore, time and location aspects of wildlife management are discussed. The model is applied to crop farming in the Netherlands. Most important model outcome is a wildlife-cost frontier at the farm level. Model outcomes show that rotating wildlife conservation practices across the farm is economically more attractive than fixed-location practices. Opportunities for use of the... |

| Based on option value theory, we develop a theoretical model to assess the dollar compensation required for the conversion to organic farming. Our empirical model is a switching regression model with two regimes and we use county level data on organic and conventional corn and soybean production in the U.S. for the application. Assuming an interest rate of 10 percent, a conventional corn-soybean grower would need to receive a one-time payment of $315 per acre to compensate for the conversion cost and an additional $1,088 per acre to conver the long run higher production and market risks. The sum of these two values equals an annual payment of $228 per acre for a 10 year contract. The results are discussed in the context of the recently introduced... |

| This paper addresses its specifics of environmental accounting for agriculture. Particularly it focuses on (a) data collecting/presenting or the environmental accounting methodology in agriculture, and. (b) indicators to measure the environmental consequences of agricultural production. The paper takes farming systems in the Tuscany Region in Italy and its specific environmental policy and management issues as a back drop. A new Environmental Accounting Information System (EAIS) is exposed that comprises both a set of environmental indicators for the evaluation of the farm externalities and the estimate of the farm environmental capital, a data collection system (the Environmental Accounting Questionnaire) and a set of elaboration methodologies for the... |

| The paper discusses the appropriate functional form and estimation technique for a wildlife production function on the farm level. A random effect model was developed to capture the relationship between wildlife output, management practices, natural conditions and non-observed factors that cause a farm specific management bias. Two wildlife measures were compared: species richness and a wildlife yardstick that enables different species to be weighed on their ecological value. The results show that the farm specific factor has a significant impact on the production of wildlife both in terms of species numbers and in terms of ecological values. Parameter estimates that were similar for the species richness specification were found to vary with the yardstick... |
