Rapid Policy Network Mapping: A New Method for Understanding Governance Structures for Implementation of Marine Environmental Policy

Understanding the relationships and dependencies in the development and implementation of environmental policy is essential to the effective management of the marine environment. A new method of policy network analysis called ‘Rapid Policy Network Mapping’ was developed that delivers an insight for both technical and non-technical users into the lifecycle, relationships and dependencies of policy development. The method was applied to the Marine Strategy Framework Directive and the Water Framework Directive in the UK. These case studies highlight the environmental policy challenges to protect the UKs marine coastal environment and they identify differences in the styles of policy implementation between the devolved authorities of the UK. Rapid Policy Network Mapping provides an opportunity to create a collaborative policy data environment with a relatively small investment. As a tool for civil society it should assist in their ability to understand and influence policy making and implementation.

Oceans of opportunity or rough seas? What does the future hold for developments in European marine policy?

The management of European seas is undergoing a process of major reform. In the past, oceans and coastal policy has traditionally evolved in a fragmented and uncoordinated manner, developed by different sector-based agencies and arms of government with competing aims and objectives. Recently, the call for integrated and ecosystem-based approaches has driven the conceptualization of a new approach. At the scale of Europe through the Integrated Maritime Policy and Marine Strategy Framework Directive and in national jurisdictions such as the Marine and Coastal Access Act in the United Kingdom, ecosystem-based planning is becoming the norm. There are major challenges to this process and this paper explores, in particular, the opportunities inherent in building truly integrated approaches that cross different sectors of activity, integrate across scales, incorporate public involvement and build a sense of oceans citizenship.

Mussels and yachts in Loch Fyne, Scotland: a case study of the science-policy interface.

We report an application of the Science and Policy Integration for Coastal System Assessment (SPICOSA) Systems Approach Framework (SAF) to Loch Fyne, a fjord in western Scotland. The issue was the potential for conflict between shellfish aquaculture and recreational use for yachting. This was investigated by building an ecological-economic model to simulate: (1) release of modern anti-fouling compounds by recreational boats; (2) dilution of these in the upper layers of the loch by exchange with the sea; (3) their effects on photosynthesis by phytoplankton; (4) the role of phytoplankton (along with non-algal particulate matter) in providing food for mussels; (5) the growth of seeded mussels to harvest, determining (6) the cash input to farms, offset by their costs and allowing (7) the farm revenue to be compared with that from marinas used to berth the yachts. It was concluded from simulations that no noticeable effect on mussel harvest would occur (from this route) for any likely number of yachts berthed in the loch. The application took place in consultation with a local environmental forum and a small reference group of public officials; we reflect on it in the context of a 3-component schema for the science-policy interface and changes in the culture of UK science.

A Review of Marine and Coastal Ecosystem Services Data and Tools to Incorporate This into Decision-Making

This chapter provides a review of marine social and economic data and tools that may facilitate the incorporation of social and economic data into decision-making for sustainable coastal management. The results show that there is good information on provisioning services and a range of methods, but social information is often lacking or not at the appropriate scale. The recommendation is therefore to further develop and adapt models that incorporate social and economic information and cover the full pathway from environmental pressures to changes in ecosystem services and human wellbeing.

Linking Ecosystem Services of Marine Protected Areas to Benefits in Human Wellbeing

This chapter examines the potential relationship between ecosystem services provided by coastal ecosystems and the design and management of Marine Protected Areas (MPAs). While all coastal and marine habitats provide a range of ecosystem services, the implementation and management of an MPA may result in improvements in the quality or supply of an ecosystem service as pressures upon protected features are minimised. This chapter focuses on the United Kingdom (UK) and examines the contrasting approaches to MPA designation applied in England, Scotland, Wales and Northern Ireland. We argue that MPAs are able to influence ecosystem services and this is dependent on design concepts such as the scale of the site, the listed features, and management measures. Understanding the portfolio of services derived from features within MPAs will improve planning and management, particularly in the context of making site specific or regional trade-offs over designation, or in understanding the benefits and impacts of setting conservation objectives and introducing measures to achieve them.

Detecting critical choke points for achieving Good Environmental Status in European seas

Choke points are social, cultural, political, institutional, or psychological obstructions of social-ecological systems that constrain progress toward an environmental objective. Using a soft systems methodology, different types of chokes points were identified in the Outer Hebrides of Scotland, the Baltic, and the North and Mediterranean seas. The choke points were of differing types: cultural and political choke points were identified in Barra and the Mediterranean, respectively, whereas the choke points in the North Sea and Baltic Sea were dependent on differing values toward the mitigation of eutrophication. We conclude with suggestions to identify and address choke points. INTRODUCTION: WHAT IS A CHOKE POINT? Here, we aim to identify choke points constraining the achievement of Good Environmental Status (GEnS) under the Marine Strategy Framework Directive (MSFD; Mee et al. 2008, Long 2011) in the seas of the Northeast Atlantic, the North Sea, the Baltic Sea, and the Mediterranean Sea. We examine the properties of choke points and indicate opportunities for decision makers to address choke points to promote the effective management of European seas. In the context of military strategy and global trade, choke points have a specific meaning: they are straits with a narrow width that constrain the number of ships passing (Smith et al. 2011, Emmerson and Stevens 2012, Roger 2012). Choke points are of strategic importance because controling them gives a state the ability to constrain the functioning of maritime transport (Noer and Gregory 1996). We apply the concept of choke points by analogy, not to narrow physical straits, but to properties of social ecological systems. We identify choke points as properties of a social-ecological system that constrain progress toward an environmental objective. Choke points are a complex mix of social, political, or psychological obstructions, congestions, or blockages that decrease the power of society to reach its objectives.

Charting the course for a blue economy in Peru: a research agenda

Ocean- and coastal-based economic activities are increasingly recognised as key drivers for supporting global economies. This move towards the “blue economy” is becoming globally widespread, with the recognition that if ocean-based activities are to be sustainable, they will need to move beyond solely extractive and exploitative endeavours, aligning more closely with marine conservation and effective marine spatial planning. In this paper we define the “blue economy” as a “platform for strategic, integrated and participatory coastal and ocean development and protection that incorporates a low carbon economy, the ecosystem approach and human well-being through advancing regional industries, services and activities”. In Peru, while the seas contribute greatly to the national economy, the full potential of the blue economy has yet to be realised. This paper presents the findings of an early career scientist workshop in Lima, Peru, in March 2016. The workshop “Advancing Green Growth in Peru” brought together researchers to identify challenges and opportunities for green growth across three Peruvian economic sectors—tourism, transport and the blue economy with this paper exploring in detail the priorities generated from the “blue economy” stream. These priorities include themes such as marine spatial planning, detailed evaluations of existing maritime industries (e.g. guano collection and fisheries), development of an effective MPA network, support for sustainable coastal tourism, and better inclusion of social science disciplines in understanding societal and political support for a Peruvian blue economy. In addition, the paper discusses the research requirements associated with these priorities. While not a comprehensive list, these priorities provide a starting point for future dialogue on a co-ordinated scientific platform supporting the blue growth agenda in Peru, and in other regions working towards a successful “blue economy”.
