| ABSTRACT: In this study, risk perception of wheat producers in Turkey was examined based on a case study conducted in Bitlis Province. The data set used in the study was obtained from 157 farmers randomly. Factor analysis was employed to classify risk sources and management strategies, and then multiple regression was used to investigate the relationship between farmers perceptions and some characteristic. Results of this study have shown that economic-based risks were perceived more strongly by farmers. Farmers’ also used more than one risk management strategy to minimize the impact of the risks they face. So, in order to ensure social and economic sustainability and predictability in wheat production and wheat market, the government should be considered... |

| This paper provides an example of a practical integration of probabilistic policy analysis and multi-stakeholder decision methods at a hydroelectric facility in British Columbia, Canada. A structured decision-making framework utilizing the probabilistic judgments of experts, a decision tree, and a Monte Carlo simulation provided insight to a decision to implement an experimental flow release program. The technical evaluation of the expected costs and benefits of the program were integrated into the multi-stakeholder decision process. The framework assessed the magnitude of the uncertainty, its potential to affect water management decisions, the predictive ability of the experiment, the value of the expected costs and benefits, and the preferences of... |

| Managing large-scale water resources and ecosystem projects is a never ending job, and success should be measured in terms of achieving desired project performance and not just meeting prescriptive requirements of planning and constructing a project simply on time and within budget. Success is more than studying, planning, designing, or operating projects. It is developing the right plan, getting it implemented, and seeing that it is operated and performs properly. Success requires all of these, and failing any of these results in wasted resources and potential for doing great harm. Adaptive management can help make success possible by providing a means for solving the most complex problems, answering unanswered questions, and, in general, reducing... |

| Resumo O monitoramento populacional de Diaphorina citri, o psilídeo--dos-citros, é essencial para o manejo regional deste inseto vetor da bactéria Candidatus Liberibacter asiaticus associada ao Huanglongbing (HLB), especialmente no cinturão citrícola de São Paulo e Triângulo/Sudoeste Mineiro, onde há a maior concentração populacional de D. citri e de plantas com sintomas da doença. Nesse sentido, o Fundo de Defesa da Citricultura (Fundecitrus) estabeleceu em 2013 o Alerta Fitossanitário para monitorar, por meio de armadilhas adesivas amarelas, a população do psilídeo em diferentes regiões do Estado de São Paulo e do Triângulo/Sudoeste Mineiro. Atualmente, o Alerta monitora 15 regiões e, a cada quinzena, gera dados de abundância (psilídeos/armadilha),... |

| Ciguatera poisoning (CP) results from the consumption of seafood contaminated with ciguatoxins (CTXs). This disease is highly prevalent in French Polynesia with several well-identified hotspots. Rapa Island, the southernmost inhabited island in the country, was reportedly free of CP until 2007. This study describes the integrated approach used to investigate the etiology of a fatal mass-poisoning outbreak that occurred in Rapa in 2009. Symptoms reported in patients were evocative of ciguatera. Several Gambierdiscus field samples collected from benthic assemblages tested positive by the receptor binding assay (RBA). Additionally, the toxicity screening of ≈250 fish by RBA indicated ≈78% of fish could contain CTXs. The presence of CTXs in fish was confirmed... |

| This article presents the results of multidisciplinary research (geochemistry, sociology) into the increasing concentrations of silver (Ag and nanoAg) in the environment and their potential impact on aquatic environments. We investigate simultaneously the risk of contamination of these environments by silver and the process of the social and political construction of this risk by water managers, health authorities, agencies and committees responsible for expert evaluations, environmental associations, and potential users of silver or nano-silver. Four updated models of risk construction allow us to understand the logic of arguments mobilized at this stage of the emerging risk. This interdisciplinary cooperation opens up possibilities for dealing with some... |

| In 2016, a massive harmful algal bloom (HAB) of Alexandrium catenella around Chiloé island caused one of the major socio-ecological crisis in Chilean history. This red tide occurred in two distinct pulses, the second, most anomalous, bursting with extreme toxicity on the Pacific coast, weeks after the highly controversial dumping off Chiloé of 4,700 t of rotting salmons, killed by a previous HAB of Pseudochattonella verruculosa. We study the transport of this pollution, analyzing the physical oceanographic conditions during and after the dumping. We find that a cyclonic gyre was present between the dumping site and the coast, visible in satellite altimetry and sea surface temperature data. Using Lagrangian simulations, we confirm that near-surface currents... |

| Biochar has the potential to make a major contribution to the mitigation of climate change, and enhancement of plant production. However, in order for biochar to fulfill this promise, the industry and regulating bodies must take steps to manage potential environmental threats and address negative perceptions. The potential threats to the sustainability of biochar systems, at each stage of the biochar life cycle, were reviewed. We propose that a sustainability framework for biochar could be adapted from existing frameworks developed for bioenergy. Sustainable land use policies, combined with effective regulation of biochar production facilities and incentives for efficient utilization of energy, and improved knowledge of biochar impacts on ecosystem health... |

| This teaching case focuses on the application of decision tools to assist managers making choices in an uncertain business climate. The case considers the difficult task of introducing a new product into the market. Under consideration is a sophisticated, surface-scanning technology that has applications in the food processing, food retail, and health industry sectors. Management of eMerge Interactive is faced with uncertainties in legislation, demand, and competitor response. The case can be used as part of a course in strategy and/or risk management where tools such as influence diagrams, scenario and payoff matrices, decision trees, and real options are introduced. |

| This report examines current trends in the U.S. grain industry. Many identity preservation(IP) grain systems have emerged recently, driven by a confluence of supply and demand factors. IP grain requirements for specific production protocols, marketing channels, and quality assurance depend on whether the crops are trait-specific, non-GM (genetically modified), organic, or pharmaceutical. Cost structures vary according to the relative importance of segregation and risk management. High information management, greater market coordination, and frequent reliance on contracts characterize IP grains. IP grain markets are also inherently riskier, with volatile supply, inelastic demand, and fluctuating price premiums. Increasing grain differentiation is altering... |

| Early-warning systems for plant diseases are valuable when the systems provide timely forecasts that farmers can use to inform their pest management decisions. To evaluate the value of the systems, this study examines, as a case study, USDA’s coordinated framework for soybean rust surveillance, reporting, prediction, and management, which was developed before the 2005 growing season. The framework’s linchpin is a website that provides real-time, county-level information on the spread of the disease. The study assesses the value of the information tool to farmers and factors that influence that value. The information’s value depends most heavily on farmers’ perceptions of the forecast’s accuracy. The study finds that the framework’s information is valuable... |

| The Farm Security and Rural Investment Act of 2002 (2002 Farm Act), which governs agricultural programs through 2007, was signed into law in May 2002. This report presents an initial evaluation of the new legislation's effects on agricultural commodity markets, based on sectorwide model simulations under alternative policy assumptions. The analysis shows that loan rate changes under the marketing assistance loan program of the 2002 Farm Act initially result in an increase in total planted acreage of eight major program crops. This increase in plantings, however, is relatively small (less than 1 percent), partly due to the inelasticity of acreage response in the sector. In the longer run, the simulations indicate that overall plantings of the eight program... |

| New revenue-based support programs in the 2008 Farm Bill represent a fundamental shift in farm programs and risk management decision-making. However, complexity, uncertainty, economics, and, arguably, an incomplete analysis of the new Average Crop Revenue Election (ACRE) program all contributed to low enrollment in the new program in 2009. An effective analysis of ACRE should consider farm programs as part of an integrated risk management portfolio, including crop insurance, marketing, and other risk management tools as opposed to a separate lottery program. Improving this integration could be one of the most significant consequences of the 2008 Farm Bill. |
