Visions for the North Sea: The Societal Dilemma Behind Specifying Good Environmental Status

We augment discussions about the Good Environmental Status of the North Sea by developing two extreme visions and assessing their societal benefits. One vision (‘Then’) assumes restoration of benthic functioning; we contend that trawling had already degraded the southern North Sea a century ago. Available information is used to speculate about benthic functioning in a relatively undisturbed southern North Sea. The second vision (‘Now’) draws on recent benthic functioning. The supply of five ecosystem services, supported by benthic functioning, is discussed. ‘Then’ offers confidence in the sustainable supply of diverse services but restoration of past function is uncertain and likely to be paired with costs, notably trawling restraints. ‘Now’ delivers known and valued services but sustained delivery is threatened by, for example, climate change. We do not advocate either vision. Our purpose is to stimulate debate about what society wants, and might receive, from the future southern North Sea.

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.
