Marine spatial planning: risk or opportunity for fisheries in the North Sea?

The North Sea is one of the busiest marine areas in the world. It is also a major fisheries ground. Bordered by seven countries with their own spatial uses and claims, the stage is set for complex and demanding governance challenges. Recent decades have also seen user groups multiply, competition for space and resources increase, and the pressure on the marine environment and its living natural resources grow. As governments strive to balance conservation and economic development needs, they also have to deal with inter-as well as intra-national user conflicts. Marine Spatial Planning (MSP) has arrived as a new approach to these issues. It is argued that for North Sea fishing people and their communities MSP holds risks as well as opportunities, depending on which institutions are formed and what role they are allowed to play in the planning process

Offshore decommissioning horizon scan: Research priorities to support decision-making activities for oil and gas infrastructure

Thousands of oil and gas structures have been installed in the world's oceans over the past 70 years to meet the population's reliance on hydrocarbons. Over the last decade, there has been increased concern over how to handle decommissioning of this infrastructure when it reaches the end of its operational life. Complete or partial removal may or may not present the best option when considering potential impacts on the environment, society, technical feasibility, economy, and future asset liability. Re-purposing of offshore structures may also be a valid legal option under international maritime law where robust evidence exists to support this option. Given the complex nature of decommissioning offshore infrastructure, a global horizon scan was undertaken, eliciting input from an interdisciplinary cohort of 35 global experts to develop the top ten priority research needs to further inform decommissioning decisions and advance our understanding of their potential impacts. The highest research priorities included: (1) an assessment of impacts of contaminants and their acceptable environmental limits to reduce potential for ecological harm; (2) defining risk and acceptability thresholds in policy/governance; (3) characterising liability issues of ongoing costs and responsibility; and (4) quantification of impacts to ecosystem services. The remaining top ten priorities included: (5) quantifying ecological connectivity; (6) assessing marine life productivity; (7) determining feasibility of infrastructure re-use; (8) identification of stakeholder views and values; (9) quantification of greenhouse gas emissions; and (10) developing a transdisciplinary decommissioning decision-making process. Addressing these priorities will help inform policy development and governance frameworks to provide industry and stakeholders with a clearer path forward for offshore decommissioning. The principles and framework developed in this paper are equally applicable for informing responsible decommissioning of offshore renewable energy infrastructure, in particular wind turbines, a field that is accelerating rapidly

Marine mammals and Good Environmental Status: Science, Policy and Society; Challenges and Opportunities

The Marine Strategy Framework Directive has become the key instrument for marine conservation in European seas. We review its implementation, focusing on cetacean biodiversity, using the examples of Spain and the Regional Seas Convention, OSPAR. The MSFD has been widely criticised for legal vagueness, lack of coordination, uncertainty about funding, and poor governance; its future role within EU Integrated Maritime Policy remains unclear. Nevertheless, the first stages of the process have run broadly to schedule: current status, environmental objectives and indicators have been described and the design of monitoring programmes is in progress, drawing on experience with other environmental legislation. The MSFD is now entering its critical phase, with lack of funding for monitoring, limited scope for management interventions, and uncertainty about how conservation objectives will be reconciled with the needs of other marine and maritime sectors, being among the main concerns. Clarity in governance, about the roles of the EU, Member States, Regional Seas Conventions and stakeholders, is needed to ensure success. However, even if (as seems likely) good environmental status cannot be achieved by 2020, significant steps will have been taken to place environmental sustainability centre-stage in the development of Integrated Maritime Policy for EU seas.Postprin

Human cell types important for Hepatitis C Virus replication in vivo and in vitro. Old assertions and current evidence

Hepatitis C Virus (HCV) is a single stranded RNA virus which produces negative strand RNA as a replicative intermediate. We analyzed 75 RT-PCR studies that tested for negative strand HCV RNA in liver and other human tissues. 85% of the studies that investigated extrahepatic replication of HCV found one or more samples positive for replicative RNA. Studies using in situ hybridization, immunofluorescence, immunohistochemistry, and quasispecies analysis also demonstrated the presence of replicating HCV in various extrahepatic human tissues, and provide evidence that HCV replicates in macrophages, B cells, T cells, and other extrahepatic tissues. We also analyzed both short term and long term in vitro systems used to culture HCV. These systems vary in their purposes and methods, but long term culturing of HCV in B cells, T cells, and other cell types has been used to analyze replication. It is therefore now possible to study HIV-HCV co-infections and HCV replication in vitro

Implementing the Marine Strategy Framework Directive: A policy perspective on regulatory, institutional and stakeholder impediments to effective implementation

The implementation of the European Union (EU) Marine Strategy Framework Directive (MSFD) requires EU Member States to draft a program of measures to achieve Good Environmental Status (GES). Central argument of this paper, based on an analysis of the unique, holistic character of the MSFD, is that social and political factors are having a major influence on this MSFD implementation process. More specifically, four potential impediments have been identified that are curtailing the drive towards the effective implementation of the scheme advanced by the Directive. First, scientific uncertainty about aggregated ecological pressure and drivers in relation to the different sectors clouds the definition of national programmes of measures and this in turn may lead to implementation-drift in achieving GES. Second, the scale of the ecosystem is different from the political and socio-economic scales of individual, sectoral decision-making and activities. Third, policy coordination is required on several levels, i.e. at the EU level, within the Regional Sea Conventions, at national level and between these three levels. Finally, the coming together of both stakeholder involvement organized for the MSFD and those of existing, sectoral policy domains makes fair and efficient stakeholder involvement challenging. This paper concludes that more attention should be rendered to establishing appropriate coordination and communication structures, which facilitate greater engagement with the different Directorates-General in the European Commission, the European Council and the Parliament, the Member States, sectoral decision making institutions as well as stakeholder interest groups
