Risk Assessment Methodology

Abstract Implementing more holistic forms of fisheries management (e.g. Ecologically Sustainable Development (ESD), Ecosystem-Based Fisheries Management) usually increases the number and scope of impacts requiring assessment. This study examined the effectiveness of a qualitative risk assessment process, developed as part of a National ESD framework, for prioritizing issues across the seven most valuable Western Australian commercial fisheries. Structured stakeholder workshops were used to identify issues across three ecological areas: retained species (i.e. target and by-product), non-retained (i.e. discarded and protected) species, and the broader ecosystem for each fishery. The risk associated with each issue was assessed using one of five sets of consequence criteria specifically developed to cover fishery-related impacts. The risk scores, for which suitably detailed justifications were written, determined the level of reporting and management required for each issue. Despite an additional 96 “non-target species issues” being identified at the workshops from a total of 115 issues, of the 27 issues requiring explicit management actions, just six new issues were added by this process. In addition, it identified where modifications of some of the existing arrangements were necessary. Finally, the system significantly improved stakeholder involvement and therefore acceptance of the outcomes. Given this success, risk assessment has now been applied to all Western Australia's export fisheries and to the development or review of many other systems, thereby improving the entire management process.

Risk Assessment Methodology

Risk assessment methodology in general has been around for quite a while, its prominence in the E-banking field is a fairly recent phenomenon. We are at the point where risk assessments are critical to the overall function of banks. Banks are required to assess the processes underlying their operations against potential threats, vulnerabilities, and their potential impact, which helps in revealing the risk exposure level, and the residual risks. Identifying clearly a risk assessment methodology is often the first step of assessing and evaluating risk associated with an organization operation. This paper presents a risk assessment methodology for Ebanking Operational Risk. The proposed risk assessment methodology consists of four major steps: a risk model, assessment approach, analysis approach and a risk assessment process. The main tool of the proposed risk assessment methodology is the risk assessment process. The assessment process gives detailed explanation with respect to which models or techniques may be applied and how they are expressed. In this paper the risk assessment technique is built upon fuzzy logic (FL) concept and Bayesian network (BN). In fuzzy logic, an element is included with a degree of membership. Bayesian network is an inference classifier that is capable of representing conditional independencies. The Bayesian and fuzzy logic–based risk assessment process gives good predictions for risk learning and inference in the E-banking systems.

<strong><em>Abstract. </em></strong>We review the impacts of towed gears on benthic habitats and communities and predict the consequences of these impacts for ecosystem processes. Our emphasis is on the additive and synergistic large-scale effects of fishing, and we assess how changes in the distribution of fishing activity following management action are likely to affect production, turnover time, and nutrient fluxes in ecosystems. Analyses of the large-scale effects of fishing disturbance show that the initial effects of fishing on a habitat have greater ecosystem consequences than repeated fishing in fished areas. As a result, patchy fishing effort distributions have lower total impacts on the ecosystem than random or uniform effort distributions. In most fisheries, the distribution of annual fishing effort within habitats is more patchy than random, and patterns of effort are maintained from year to year. Our analyses suggest that many vulnerable species and habitats have only persisted in heavily fished ecosystems because effort is patchy. Ecosystem-based fisheries management involves taking account of the ecosystem effects of fishing when setting management objectives. One step that can be taken toward ecosystem-based fisheries management is to make an a priori assessment of the ecosystem effects of proposed management actions such as catch controls, effort controls, and technical measures. We suggest a process for predicting the ecosystem consequences of management action. This requires information on habitat distributions, models to predict changes in the spatial distribution of fleets following management action, and models of the impacts of trawling disturbance on ecosystem processes. For each proposed management action, the change in disturbance affecting different habitat types would be predicted and used to forecast the consequences for the ecosystem. These simulations would be used to produce a decision table, quantifying the consequences of alternative management actions. Actions that minimize the ecosystem effects of fishing could then be identified. In data-poor situations, we suggest that management strategies that maintain or maximize the patchiness of effort within habitat types are more consistent with the precautionary approach than those that lead to more uniform fishing effort distributions.

Before initiating a project, risks assessment, is a process that its importance has felt in past two decades and has taken a position in project activities. Project's managers apply risk assessment as a preventive method for highly possible risks having an unfavorable influence on project objectives. Risk assessment has implemented in three ways: qualitative, semi-qualitative (semi-qualitative) and quantitative. In this paper, the author reviews quantitative and semi-qualitative risk assessment methods in associated with fuzzy sets theory (FST). Moreover, considering three steps of risk assessment process, namely: definition and measurement of parameters, fuzzy inference and defuzzification, the author classified presented articles into three groups of giving opinion methods, assessment methods and defuzzification methods. It is avoided mentioning articles with same assessment methods in this paper. Although giving opinion methods and defuzzification methods have the potential to be worked on, late risk assessment surveys, demonstrate increasing attempt on developing comprehension and reality adjustment in project risk assessment methodologies.

Climate change is affecting human and geophysical systems in a variety of complex and interdependent ways. For nature-based tourism-dependent communities like those along the North Shore of Lake Superior in Minnesota, impacts to the region’s abundant natural resources can subsequently affect the livelihoods of individuals who depend upon those resources to provide essential ecosystem services and support the region’s economy. Many of the area’s natural and outdoor recreation resources are collaboratively managed, making cooperation essential to address climate change impacts. In this study, we engaged North Shore stakeholders in a climate change risk assessment process through an exploratory application of participatory geographic information systems (PGIS). Stakeholder involvement allows for the co-production of science to deliver locally-relevant data and information. Involving stakeholders through a PGIS-based climate change risk assessment process allows locally-relevant data and information to be represented and visualized spatially. We used PGIS focus groups, as well as pre- and post-surveys, to solicit stakeholders’ perceptions of risk thresholds (i.e., the time scale of impacts) and climate-related risk severity to sites with built infrastructure, natural amenities, and recreation and tourism destinations. The stakeholders’ knowledge, as well as their commitment to their communities and local environments, influenced general perceptions of region-wide climate-related vulnerabilities. The PGIS exercises generated important discussion among stakeholders and shed light on how to more efficiently collect spatially-explicit data and information from stakeholders that can be used to inform mitigation and adaptation efforts.

Risk management is becoming increasingly more complex. Risk assessment, approached quantitatively, requires a factual database to define the likelihood of adverse health effects of workplace-related injuries and exposures, and it attempts to balance scientific knowledge with concerns of staff, investigators and administration. Practical guidance should be provided for Romanian coal mining companies to make progress in risk assessment process. Guidance is given on how to effectively introduce quantitative risk assessment in mining industry, the main goal being to highlight that the most valuable resource remains experience gained by effectively performing the process. Analyzing how various parameters are described/used, the paper aims to establish the place and role of quantitative risk analysis mining. Possibilities of developing safety/reliability database in coal mining are investigated. The block diagram describing the conceptual structure of a database on failures, safety of equipment and workers in the mining industry was developed. Because mining relies heavily on complex technologies - permanent mining facilities and large mobile equipment and support services - often located in isolated and hostile environments, the implementation of quantitative risk analysis and the development of a realistic database could be considered as a resilience business strategy and conversion of available knowledge into management actions.

This paper explains how the results of the source water characterisation for the Western Corridor Recycled Water Project in South East Queensland was used to augment the qualitative water quality risk assessment process and design of the monitoring programs. Results were evaluated against health standards published in 2008 by Queensland Health and also against level of reporting. This determined the relative risk of exceeding the health standard for parameters detected in the source. The relative risk was used to inform the qualitative risk assessment as well as the frequency of monitoring in both the source and purified water. Categorising hazards using their ionic charge and hydrophobicity enabled the selection of indicators for both source and purified water compliance monitoring programs.

Horizon Scanning

Early detection and eradication of invasive plants are more cost-effective than managing well-established invasive plant populations and their impacts. However, there is high uncertainty around which taxa are likely to become invasive in a given area. Horizon scanning, which pairs rapid risk assessment with consensus building among experts, can help identify invasion threats. We performed a horizon scan of potential invasive plant threats to Florida, USA—a state with a high influx of introduced species, conditions that are favorable for plant establishment, and a history of negative impacts from invasive plants. We began with a list of 2128 non-native plant species and subspecies that are crop pests or invasive somewhere in the world and used publicly available data to prioritize 100 taxa for rapid risk assessment. We derived overall invasion risk scores by evaluating the likelihood and certainty of each of the 100 taxa arriving, establishing, and having an impact in Florida. Through the rapid risk assessments and a consensus-building discussion, we identified six plant taxa with high overall risk scores ranging from 75 to 100 out of a possible 125. The six taxa are globally distributed, easily transported to new areas, found in regions with climates similar to Florida’s, and can impact native plant communities, human health, or agriculture. We recommend more thorough risk assessments for each of these six species and, if appropriate, policy and management actions to limit invasive plant introduction and establishment in Florida.
