Management Approaches

Abstract Risk assessment is the management approach or framework of choice in many disciplines, including health care and research, engineering design, and particularly the insurance sector which relies on the best available forward projections of natural hazards and accidents. The marine management community, which includes researchers, practitioners, and resource managers responsible for individual targeted stocks, aquaculture activities, and the marine environment in general, has been slower to take up quantitative risk assessment approaches. Whilst there are prominent examples where risk assessment and management approaches have been applied, they are relatively few. This article theme set presents examples of such and identifies tools and approaches that can be applied to coastal and oceanic marine systems worldwide. The methods developed and the lessons learned from these studies can be used to guide researchers, practitioners, and resource managers. It is hoped that this article theme set will provide an overview of the current state of risk assessment as applied to marine resource management, and stimulate new thinking on how risk assessment approaches can be applied.

Managing the transportation of dangerous goods (DG) through road tunnels is of great importance since it is associated with a serious risk of accidents. The consequences of an accident involving DG, especially in the closed tunnel environment, might be more significant and even more catastrophic compared to the same accident occurring on an open road. This article presents the Greek experience regarding the application of quantitative risk assessment (QRA) methods for the transportation of DG through Greek road tunnels. The modified Delphi method, with the participation of nine experts, is employed to investigate the obstacles to successfully conforming with the mandatory European Union regulatory framework that applies to transport operations within the Trans-European road network. Recommendations are made to improve the applied QRA approach, to facilitate the cooperation between tunnel managers and emergency services, to communicate lessons learned and to enhance the training of risk assessors.

SUMMARYIn recent years, the term ‘adaptive management’ has become integrated in government agriculture and conservation programmes in the United States. Adaptive management is described as ‘a process of developing improved management practices for efficient production and resource conservation by use of participatory learning through continuous systematic assessment’, by the NEERA1002 Coordinating Committee on Adaptive Nutrient Management. Such developments reflect recognition by government agencies of (1) the need for continuous improvement in managing agricultural systems to enhance productivity and environmental protection at farm, state, watershed and federal levels, and (2) the effectiveness of continuous systematic assessment and an outcome-based evaluation in achieving and documenting such progress. Various methods have existed for knowledge development and transfer in the past, some effective, others less successful. The present paper presents and discusses lessons learned from three different adaptive management approaches, implemented at field, whole farm and regional/state levels, which contributed to improvements in field, farm and regional/state balances for nitrogen and phosphorus in New York. These examples show that a combination of governmental regulations and an innovative, outcome-focused adaptive management approach that includes research, extension, and a focus on human dimensions (a people-based approach) will be most effective in obtaining greater sustainability of agriculture in future years.

Risk assessment is one of the main tools that oil and gas industries use to assess the hazards and risks in their facilities worldwide. Qualitative and quantitative risk assessments are carried out at various phases of the process industry: conceptual stage, design stage, construction stage, operational stage, decommissioning stage, etc. The quantitative risk assessment is directed during the detailed design stage to decide the spacing and layout out of equipment for safe operation and maintenance of oil and gas industries. The equipment layout and spacing are based on the safe distances are to be carried out on various design safety studies. In this work, a study was carried out on upstream onshore natural gas gathering stations and associated equipment and pipeline networks. The fire, explosion assessment, and toxic gas dispersion are conducted to evaluate how it affects people, assets, and the environment. Whether the design protection systems are adequate to mitigate the consequences or any additional measures to reduce risk to an acceptable level is analyzed.

Production of Oil & Gas in offshore involves some of the most ambitious engineering projects of the modern world, is a prime source of revenue for many countries. It is also involved risks of major accidents which have been demonstrated by disaster on the UK production platform Piper Alpha. Major accidents represent the ultimate, most disastrous way in which an offshore engineering project can go wrong. Accidents cause death, suffering, environmental pollution and disruption of business. To ensure all risks identified and controlled, risk management approaches need applying. This paper discusses the application of quantitative risk assessment approaches and its importance throughout the entire offshore installation.

The paper presents the concept of risk portfolio management – a holistic approach to risk analysis. It summarizes current state of knowledge regarding examined topic. Assessment of the suitability of portfolio management approach in the enterprise risk management was based on review of the subject literature. The author makes an attempt to confirm the hypothesis of risk portfolio management being a necessary and key part of proper enterprise risk management. The first section of the article provides a brief overview of the evolution of risk management. In the succeeding sections, descriptions of two latest risk management approaches: the traditional, silo risk management and the Enterprise Risk Management (ERM) approach are followed by a presentation of the risk portfolio management concept, which is compared to stock portfolio management. The paper focuses on the kinds of dependencies between certain risks which should be particularly considered and the ways in which portfolio analysis can be used to enhance a company’s understanding of its risks and enable it to make better management decisions. The last section of this paper presents potential effects of the implementation of the portfolio approach, focusing on benefits of portfolio management in a company’s activities.

Water quality standards set in the past have not helped resource managers in the decisions that they face in seeking sustainable development. Resource managers are looking for meaningful information on water quality so as to evaluate the resource, set priorities for action, and to monitor progress. Resource managers need to know how water quality affects, and is affected by, catchment uses and activities. Examples of three wild and scenic rivers, the Nymboida, Murrumbidgee, and Hawkesbury/Nepean River systems, demonstrate how a ‘Total Catchment Management' approach to resource use and resource protection has advantages for water quality management.

Campylobacter Spp

Shellfish are frequently contaminated by Campylobacter spp, presumably originating from faeces from gulls feeding in the growing or relaying waters. The possible health effects of eating contaminated shellfish were estimated by quantitative risk assessment. A paucity of data was encountered necessitating many assumptions to complete the risk estimate. The level of Campylobacter spp in shellfish meat was calculated on the basis of a five-tube, single dilution MPN and was strongly season-dependent. The contamination level of mussels (<1/g) appeared to be higher than in oysters. The usual steaming process of mussels was found to completely inactivate Campylobacter spp so that risks are restricted to raw/undercooked shellfish. Consumption data were estimated on the basis of the usual size of a portion of raw shellfish and the weight of meat/individual animal. Using these data, season-dependent dose-distributions could be estimated. The dominant species in Dutch shellfish is C. lari but little is known on its infectivity for man. As a worst case assumption, it was assumed that the infectivity was similar to C. jejuni. A published dose-response model for Campylobacter-infection of volunteers is available but with considerable uncertainty in the low dose region. Using Monte Carlo simulation, risk estimates were constructed. The consumption of a single portion of raw shellfish resulted in a risk of infection of 5–20% for mussels (depending on season; 95% CI 0.01–60%). Repeated (e.g. monthly) exposures throughout a year resulted in an infection risk of 60% (95% CI 7–99%). Risks for oysters were slightly lower than for mussels. It can be concluded that, under the assumptions made, the risk of infection with Campylobacter spp by eating of raw shellfish is substantial. Quantitative risk estimates are highly demanding for the availability and quality of experimental data, and many research needs were identified.
