Abstract

There is growing evidence that the ecosystem service (ES) concept can provide valuable input to marine spatial planning (MSP), by highlighting which ecosystem goods and services can be produced from a planning area. ES link the underlying ecosystem processes and functions to the benefits humans can receive from ecosystems (the ecosystem cascade). In this study, we argue that the ecosystem cascade can be used to structure the stock-taking and future scenario analysis in MSP.However, indicators, which are needed for measuring ES, have often been applied in various ways to the different steps of the cascade. Here, we apply a consistent approach to sorting indicators into the cascade. The indicators are presented in an indicator pool that can be used to filter them based on the cascade steps, several quality criteria, and themes. The pool consists of 772 indicators, of which 735 were analyzed. In total, 252 analyzed indicators belong to the provisioning services, 314 indicators to the regulating services and 169 to the cultural services. The indicator pool offers a suitable starting point to select indicators for ES assessments within MSP. Using indicators at the different cascade steps allows the assessment of i) the ecosystem components generating the services and ii) the impacts on ES and their beneficiaries when changes occur in the provision of the services due to planning or management decisions.

Highlights

There is a growing demand for the sea space due to an expansion of traditional maritime sectors and emerging marine uses, such as wind farms and mariculture
Based on Classi fication of Ecosystem Services (CICES) V5.1, in total, 62 ecosystem service (ES) classes were selected to be relevant in the marine environment (Supplementary Information A)
This study shows that the cascade can be used to structure indicators in a meaningful way for ES assessments within Marine spatial planning (MSP)

Summary

Introduction

There is a growing demand for the sea space due to an expansion of traditional maritime sectors and emerging marine uses, such as wind farms and mariculture. MSP needs to strike a balance between increasing maritime uses (fostered by the EU Blue Growth strategy (EC, 2012), for example) and the sustainable development of these activities within the natural limits (i.e., the carrying capacity) of the ecosystem (Hassler et al, 2019). The latter emphasizes the ecosystem approach to MSP that considers the entire ecosystem. The ecosystem approach en compasses the view that present and future generations should be able to continue using the goods and services provided by the sea (UNCED, 1992; UNEP, 2011). In the EU, the ES concept has made its way into relevant, marine-related legislation, such as the Marine Strategy Framework Directive (MSFD) (EC, 2008) and the Directive establishing a framework for maritime spatial planning (MSP Directive) (EC, 2014)
