Coastal nature-based solutions (NbS) are increasingly recognized for their multiple benefits to socio-ecological systems, including climate mitigation and adaptation (e.g. conservation, restoration and sustainable management of coastal ecosystems for climate). National climate plans, such as the Nationally Determined Contributions (NDCs) developed...
In line with international frameworks and following the example of other countries, France conducted a national ecosystem services (ES) assessment in 2012. National assessments are intended to be both comprehensive and useful. In practice, these objectives are conflicting and difficult to reach, leading the experts in charge of the assessment to al...
This paper aims to find mechanisms to align commercial interests with underwater noise reductions from commercial shipping. Through a survey and a series of interviews with representative stakeholders, we find that while acknowledging the wide variations in ports' specificities, port actions could support the reduction in underwater noise emissions...
The shifting policy focus towards Ecosystem Based Management in Fisheries (EBFM) requires the integration of knowledge and disciplines and the engagement of stakeholders to support decision-making processes. Scientists contribute to this through (i) participatory research projects, (ii) stakeholder partnerships and (iii) institutional scientific ad...
Blue-green infrastructure (BGI) is becoming a more popular means of dealing with climate change and climate change-related events. However, as the concept of BGI is relatively new, many urban and rural planners are unfamiliar with the barriers they may face during the lifecycle of a BGI project. As a result, some have been hesitant to adopt BGI sol...
The implementation of the European integrated marine policy poses many scientific challenges. Among them, the knowledge and understanding of interactions between anthropogenic pressures and ecological components is an important issue, particularly to help define Good Environmental Status, environmental targets and monitoring programs of the Marine...
With growing interest in ocean uses for sustainable economic development, there is an increasing need for cross-sectoral marine spatial planning to balance different resource uses and conservation requirements. Ecosystem service assessments can provide the evidence to inform marine spatial planning decisions. Existing case studies suggest that thes...
The health of the ocean, central to human well-being, has now reached a critical point. Most fish stocks are overexploited, climate change and increased dissolved carbon dioxide are changing ocean chemistry and disrupting species throughout food webs, and the fundamental capacity of the ocean to regulate the climate has been altered. However, key t...
Si l’idée que la Nature rend à l’Homme des services indispensables est très ancienne, l’approche par les services écosystémiques a gagné une reconnaissance universelle avec la réalisation du Millenium Ecosystem Assessment au début des années 2000. Dans l’acception contemporaine de cette notion, les évaluations de services écosystémiques doivent ava...

Stakeholder Perception on Maritime Spatial Planning
This document sums up the main finding of the SIMNORAT “stakeholder engagement in MSP” component, which aimed to assess stakeholders’ perception of MSP and to support their engagement in the process, particularly concerning crossborder aspects.
One of the current major scientific challenges to sustain social-ecological systems is to improve our understanding of the spatial and temporal dynamics of the relationships between biodiversity, ecosystem functioning and ecosystem services. Here, we analyze the bundles of ecosystem services supplied by three coastal ecosystems (coastal lagoons, co...
The specific objective of this component was to support good practice in stakeholder engagement within the transboundary context of MSP. The aim was to engage stakeholders to discuss about the Marine Spatial Planning (MSP) process and its cross-border dimension as well as to support dissemination of good practice in stakeholder engagement, and so p...
Since the 1990s, the Intergovernmental Panel on Climate Change (IPCC) has used global assessments of vulnerability to inform investment and action against the effects of climate change. Beyond the IPCC, others have undertaken global assessments to understand the vulnerability of coastal areas to climate change. Eight global vulnerability assessment...

Ecosystem resilience is the capacity of ecosystems to tolerate disorders without collapsing into different circumstances qualitatively controlled by a different set of processes. A robust ecosystem is one that can withstand shocks and rebuild itself when necessary. This study aims to identify the value of use-based economy and non-use value of curr...

In order to promote future sustainable development of coastal zones, technology-push, market pull, and government-led incentives for marine biotechnology became important issues to be discussed at a global scale today. Many marine resources could be transformed by marine biotechnology into food, medicine, cosmetic and energy. The marine biotechnolo...
In this paper, we propose an alternative preference uncertainty measurement approach where respondents have the option to indicate their willingness to pay (WTP) for a nature protection program either as exact values or intervals from a payment card, depending on whether they are uncertain about their valuation. On the basis of their responses, we...

Many marine resources could be used by marine biotechnology in order to be transformed into food, medicine, cosmetics and energy. The marine biotechnology is not restricted at creating new industrial products; it could also contribute to the bio-economy and grand societal challenges. The golden triangle of blue growth (marine resources, demand and...
Sustainability Science is emerging as the transdisciplinary research field that provides information and technical support needed for Sustainable Development (SD). It has complex and far reaching implications for research and for society. SD is a learning process that requires difficult social changes in paradigms and behaviors. This process involv...
ICZM depends on an understanding of the coastal zone system to be managed. During the SPICOSA project, the authors' task was to provide teams engaged in applications of the 'Systems Approach Framework' with a theoretical basis for understanding these systems in terms of ecological, economic, and social structures and processes. This chapter briefly...
Le très long terme, pour l'économie, la sociologie, le droit et les sciences politiques relève de la réflexion séculaire ou pluriséculaire. Il est donc au-delà de la prévision, il ne peut guère relever que de la prospective et de la futurologie. Imaginons la question posée sous la révolution! Or les évolutions démographiques et technologiques ont-é...

This article explores the value of the Systems Approach Framework (SAF) as a tool for the transition to sustainable development in coastal zone systems, based on 18 study sites in Europe, where the SAF was developed and tested. The knowledge gained from these experiments concerns the practical aspects of (a) governance in terms of policy effectiven...
the quantitative water management of the Charente River in France is a major policy concern because of freshwater scarcity in summer. In the context of SPICOSA project (Science and Policy Integration for Coastal System Assessment),) this policy issue was chosen to apply the System Approach Framework (SAF) methodology. This led to modeling irrigatio...
We analyse how to improve participatory modelling aimed at addressing complex socioecological
problems when it is driven by one of the actors involved. Whether they are stakeholders,
modellers, decision-makers or even researchers, such “actor-driven” approaches lead to significant drifts in
the process of engagement and have raised many doubts abou...
This Special Feature Volume examines the potential value of the Systems Approach Framework (SAF) as a methodological framework for the transition to sustainable development in coastal zones. This article provides insight on the Systems Approach, the theory behind it, and how its practical application to coastal zone systems (CZSs) was developed. Th...
Tax and entrance fee effects on tourists’ willingness-to-pay for new nature reserves in the Gulf of Morbihan
Using contingent valuation method, this paper empirically examines the effects of a special accommodation tax and an entrance fee on tourists’ willingness-to-pay (WTP) for new nature reserves in the Gulf of Morbihan (France). The results sho...
In this paper, we develop an empirical test of consistency in contingent willingness to pay (WTP) responses, which is based on the following a priori expectation. In economics, when an individual considers paying for public goods, his decision to pay, and his WTP are based on utility-maximising behaviour. Accordingly, supposing other factors are id...
Biological diversity, or biodiversity, is high on the international agenda for nature conservation. Marine and coastal ecosystems account for an important share of the biological diversity on Earth. As a consequence many international conventions, European legislation and national laws refer to marine biodiversity. The protection of marine biodiver...
For a long time, shrimp farming in Vietnam remained underdeveloped, in spite of good potential in terms of natural resources and farming area.Alack of investment, capital, technology, and knowledge have been the main restrictive factors. This potential was then exploited, at a time when many shrimp producers were facing problems and collapses in ot...

1. The ASTRODOME research project aims to study the economic aspects of the system of allocation and transmission of shellfish concessions, which is considered as an essential element in the understanding of the occupancy strategies of the coastal maritime space. Two series of questions are highlighted. The first series examines the system from a s...
Observation of the process of assessing and compensating damages caused by oil spills at sea shows that in most cases, it is difficult to establish a single global estimate of their social cost. Three categories of numbers regarding the costs of pollution are usually encountered following spills: (i) estimates by experts; (ii) compensation claims;...
For three years, a multidisciplinary group of researchers in social sciences, has analysed the Ethical, Legal and Social Aspects of fisheries management in Europe.
