Detecting dispersal pathways is important both for understanding species range expansion and for managing nuisance species. However, direct detection is difficult. Here, we propose detecting these crucial pathways using a virtual ecology approach, simulating species dynamics using models, and virtual observations. As a case study, we developed a dispersal model based on cellular automata for the pest insect Stenotus rubrovittatus and simulated its expansion. We tested models for species expansion based on four landscape parameters as candidate pathways; these are river density, road density, area of paddy fields, and area of abandoned farmland, and validated their accuracy. We found that both road density and abandoned area models had prediction accuracy. The simulation requires simple data only to have predictive power, allowing for fast modeling and swift establishment of management plans. [ABSTRACT FROM AUTHOR]

In this study, we propose a method for estimating the risk of agricultural damage caused by an invasive species when species-specific information is lacking. We defined the 'risk' as the product of the invasion probability and the area of potentially damaged crop for production. As a case study, we estimated the risk imposed by an invasive weed, Sicyos angulatus, based on simple cellular simulations and governmental data on the area of crop that could potentially be damaged in Miyagi Prefecture, Japan. Simulation results revealed that the current distribution range was sufficiently accurate for practical purposes. Using these results and records of crop areas, we present risk maps for S. angulatus in agricultural fields. Managers will be able to use these maps to rapidly establish a management plan with minimal cost. Our approach will be valuable for establishing a management plan before or during the early stages of invasion. [ABSTRACT FROM AUTHOR]

- Abstract
This paper aimed to evaluate impacts of risk management (RM) on sheep production. It is based on Solvsamp Modeling, to analyze empirical data (2003-2011) obtained in two marketplaces. Results proved that RM was sometimes ineffective against natural agent severity or market prices fundamental elements (supply, demand) which would have caused strongly risks within season independently of one another. With government policies producers based their RM tools on the use of concentrated animal feed input and herd size management, either this last or herd mobility (nomadic, transhumant) and animal feed diversification, but the RM strategies and returns for individual farmer looked like at a point in time. RM ensured for producers the margin profit rate of 15 percent in winter to 33 percent (summer) and conversely high seasonal coefficient (1.25) in winter, low (0.86) in summer. RM must consider the seasonal, economic or policy factors and specificity of each breeding system to be more efficient. [ABSTRACT FROM AUTHOR]

Weather index-based crop insurance is increasingly becoming important as a risk mitigation strategy that farmers may use to mitigate adverse climate shocks and natural disasters encountered during farming. While Europe, North America, and Asia account for 20.1%, 55%, and 19.5% of the total agricultural insurance premium worldwide, respectively, Africa accounts for only 0.5% of the world insurance industry. One of the key reasons advanced against the low index insurance participation rate in Africa is the failure to involve farm households at the initial conceptualization and design of pilot initiatives. Therefore, the main purpose of this paper is to design an improved participatory methodology that could help elicit information on the value placed by farm households in Southwestern Burkina Faso on a new weather index-based crop insurance management initiative. A key concept in the improved participatory methodology is that of the willingness to pay (WTP) of farm households for the scheme. Knowledge of the maximum amount that farmers are willing to pay for the scheme can help insurance policy providers and public policy makers to design and put in place measures that sustain index insurance schemes in a developing country context and improve welfare among participating farmers.

The objective of this paper is to develop an approach for integrating a gender dimension into Agricultural Sector Risk Assessments (ASRAs). The focus is on the approach because both agricultural risk and gender issues are contextual, thus the outcomes of a gender-based risk assessment are highly dependent on the social, cultural, geo-graphic, and economic contexts of the setting in which the assessment is applied. The organization of the paper reflects the challenges of incorporating a gender dimension into ASRAs. The conceptual framework and step-by-step illustrations presented herein are based on lessons learned by the World Bank and other institutions in assisting developing economies in conducting sector and key commodity supply chain risk assessments (World Bank 2015a). The paper also relies on recent work by international institutions and academic research that offer insights into the complexities of gender issues in relation to agricultural shocks. These experiences inform this paper’s case for a gender-based approach to Agriculture Risk Management (ARM) and help to illustrate a practical, stepwise approach for conducting gender-based ASRAs. This paper is arranged as follows: Chapter 2 offers a summary of the conceptual framework for risk management, including addressing why a gendered approach to ASRAs is essential; Chapter 3 shows the available evidence that agricultural risk has a gender-differentiated impact on farming households and that farming households adopt a gender-differentiated response to risk; Chapter 4 describes a step-by-step operational approach for doing so, and includes guidance for formulating gender-smart policies and strategies for strengthening agricultural systems’ resilience; and Chapter 5 presents a summary of findings and concluding remarks.

Agriculture is a unique sector because of its dependence on the climate and biological variables. Therefore, in agriculture it is vital to identify and evaluate risks to be sure that decisions made on the farm will bring positive results. Scientific literature describes a lot of risk evaluation methods. However it is not easy to see which methods should be used in the agricultural sector. This article describes the main types of risk in agriculture, their features and their relevance with respect to scientific theories. Secondly, it introduces the most popular risk evaluation methods and their potential use in agriculture and finally presents a logical framework of integrated risk evaluation.

- Abstract
The 2018 Farm Bill has reopened commodity program enrollment for producers, and thus renewed interest in the Supplemental Coverage Option (SCO) of the Federal Crop Insurance Program (FCIP). This thesis examines the potential risk management benefits afforded to Kentucky corn, soybean and wheat producers by the SCO. A simulation model is used to rank downside-risk minimization of the common Multi-peril Crop Insurance Policies (MPCI) policies both with and without the SCO for various farm-level yield risk and farm- to SCO area-level yield correlations. The study found that the SCO endorsement was a component of every optimal insurance choice for all possible combinations examined in this study. Soybeans had the greatest homogeneity, while wheat had the greatest variability in optimal insurance choice. The results show that the SCO should enter into a producer's crop insurance decision and also commodity program enrollment decision — when applicable. The yearly commodity program enrollment deadlines occurring throughout the life of the current Farm Bill make this study especially timely.

Risk management of crop related exposures in coastal regions can be enhanced through a program of hazards modeling and real-time forecasting. As one component in the yield distribution of selected crops, typhoon-related hazards are a critical factor. Natural typhoon occurrence rates accentuate the extreme parts of the yield distribution, causing severe and correlated financial disruptions to invested interests. This paper outlines a suite of techniques focused on building a probabilistic understanding of crop risk from tropical cyclones. Several foundational technologies are discussed, including: Numerical Weather Prediction (NWP) of tropical cyclones; statistical consensus forecast models, such as the WeatherPredict Superensemble™; and the application of flood modeling techniques to typhoon landfall scenarios.
