| In the Brazilian agriculture, there is a great diversity and heterogeneity of production systems that are subject to wide number of factors of risks. Although these risks cannot be completely eliminated, they can be minimized by adopting some strategies, as the diversification with agricultural and cattle activities. Based on the research historical results of the Paraná’s agriculture e with the measurement of the value-at-risk, this work aimed to analyze the volatility of the economic returns of integrated crop-beef cattle systems compared to systems characterized by grain cultivation or beef cattle specialization. As results, we observed that, in the short-term, the integrated crop-livestock system is the alternative that trends to generate better... |

| Veggies 4U is a young and dynamic family-run greenhouse: Lucy and her husband run the business with the help of a small group of friends and colleagues who serve on the company's Board of Directors. Lucy is preparing a report to the Board to recommend a natural gas supply contract for the next three years. The company has received four different contract offers, ranging from a simple forward contract, to a maximum cost contract with a price floor. The case focuses on the pricing and risk management opportunities offered by an integrated North American natural gas market. Lucy has to assess the different supply contract offers received by the company and to reverse engineer them in order to benchmark their cost with that of potential synthetic alternatives... |

| Contractual arrangements for joint machinery ownership between independent agribusinesses are explored. A two-farm economic simulation model of locations in Texas, Colorado, and Montana is developed to provide insight associated with sharing combines. Important variables include combine size (efficiency), yield losses resulting from untimely access to equipment, the penalty structure for untimely delivery, and cost-sharing and depreciation deductions claimed between producers. Combine sharing is risk-reducing in most cases. The gains to both parties are lowest when harvesting periods overlap. While the value of sharing is positive under many scenarios, benefits from sharing are small relative to total farm revenue. |

| The paper addresses "food safety" and 'food quality' from the position of commodity and food science rather than economy. The various descriptions of both terms in literature are reviewed in connection with customer/supplier ability to evaluate food safety and quality by examination of various characteristics. Food safety has been described as opposite to food risk. Differences in perception of food risk by customer, producer/supplier and official agencies are discussed in this paper. The objective safety (and quality) of food can be evaluated using three categories of food risk (biological, chemical and physical) measured on a seven step intensity scale by producers and official agencies but not by customers. This leads to formulating food safety policy... |

| This study evaluates both the profitability and risk efficiency of grazing stocker steers on conservation tillage winter wheat pasture using simulation and stochastic efficiency with respect to a function (SERF). Average daily gains are simulated for steers grazed on conventional tillage (CT), reduced tillage (RT) and no-till (NT) winter wheat pasture. Steer price distributions and prices for key production inputs such as diesel, fertilizer, and glyphosate are also simulated. Stocker steer net return distributions by tillage treatment are constructed and ranked for risk efficiency using SERF. The results indicate the NT system is the most profitable and most risk efficient of the three tillage systems, followed by the RT system. Both conservation tillage... |

| Lending and financial institutions have looked for a variety of ways to expand their portfolios into agriculture, but because of the risks associated with lending to farmers who lack traditional forms of collateral, they face price and yield risks, causing these inroads to be limited. Market-based instruments are readily available for price risk. Organised exchanges offering the most basic of these instruments, futures and options, have operated for a long time, providing transparency to the market and low-cost risk transfer tools for those able to access them. While the use of price risk management instruments is an incomplete solution, it has sufficient merits on its own and will make the overall burden of risk more bearable. The use of these instruments... |

| This paper extends the long-term cash-flow simulations reported in Part I (Hutchings 2009) to include a range of seasonal scenarios at four representative dryland sites in south-eastern Australia. The effect of varying the proportion of sheep and cropping in the enterprise mix at each site on cash surpluses is discussed. The analysis shows that, for most sites, the cropping enterprises require better than average seasons, prices and water-use efficiencies to generate a positive cash flow and are subject to substantial variability and risk of loss. In contrast, the sheep enterprises show small but stable cash flows in all but extreme drought conditions. This paper emphasises the need to include site-specific, long-term variability and whole-farm costs in... |

| In the paper we investigate the role played by both production and market risks on farmer’s decision to adopt long rotations (over 2 years), considered as innovative cropping systems. We build a multiperiod dynamic farm model (run under GAMS) that arbitrates each year between traditional and innovative rotations. With discrete stochastic programming, the production risk is accounted as an intra-year risk; yearly farming operations are declined according to a decision tree where probabilities are assigned. Subjective yield and cost distributions linked to this decision tree are elicited among a sample of 13 farmers that are experiencing this innovation in South-western France. The price risk is randomly distributed with a given market trend. The crop... |

| Esse trabalho teve como objetivo verificar a viabilidade financeira da implementação de um sistema automatizado de irrigação por miniaspersão na cultura do feijão. O trabalho toma como referência a teoria de análise financeira de investimentos, considerando a abordagem determinística e probabilística. Os dados relativos à produtividade do feijoeiro, ao sistema de irrigação por miniaspersão, bem como os coeficientes técnicos, os custos de produção e as receitas de venda foram baseados em experimentos e coletas de dados realizados por pesquisadores da UFV. Diante dos resultados, pode-se concluir que tanto nos cenários determinístico e probabilístico, o projeto de irrigação por miniaspersão na cultura de feijão apresenta-se viável. O projeto é... |

| Many policy issues, as well as policy funding and management choices, have elements of risk and uncertainty. This means that choice experiments, such as those used in choice modelling (CM), may need to frame trade-offs so that risk and uncertainty are included. This research aims to explore some methodological approaches to identify and treat uncertainty in CM experiments. A review of theoretical models, as well as a case study application in the CM technique reported by Roberts et al. (2008), suggests that including uncertainty information in the choice sets should influence responses significantly. However, key challenges remain to define and describe the elements of risk and uncertainty that are to be included in a choice experiment, to communicate the... |
