This paper describes an empiric study of aggregation and deliberation—used during citizens’ workshops—for the elicitation of collective preferences over 20 different ecosystem services (ESs) delivered by the Palavas coastal lagoons located on the shore of the Mediterranean Sea close to Montpellier (S. France). The impact of deliberation is apprehen...

Les demandes et les usages des données spatiales satellitaires se développent et se diversifient de façon importante, en lien avec la précision, la fréquence des prises de vue et la taille des images. Ainsi, il convient de comprendre et de rendre compte des impacts de cette production croissante sur l’organisation et la rationalisation des structur...
Article
Drawing on the results of two research programs undertaken in France, we consider environmental inequality and regional solidarity in the context of adaptation to sea-level rise, given that there is in France a bespoke national system for natural-disaster solidarity. The analysis makes it possible to address situations of inequality, in particular...
Article
Ecosystem Services (ES) can contribute to several aspects of human well-being (WB) that we understand as the subjective perception that individuals have of their quality of life, depending on a set of factors. We compare the relative weights of the WB factors resulting from ES (ES-based) and those that do not depend on ES (non-ES-based), from an on...
Chapter
Risk managers share experiences and knowledge related to the territory in which they operate. This construction of memories allows an appropriation and a mastery of the territory. However, when it comes to anticipating a risk, how do these stable and shared memories come into play? Can they influence appropriate management? Semi-structured intervie...
Article
Policies aimed at adaptation to sea-level rise advocate new approaches, no longer based only on protection but also seeking to reduce the vulnerability of densely-urbanized coastal zones, especially through managed retreat or anticipatory relocation. However, such relocation faces substantial challenges and constraints at all governance and policy...
Article
Full-text available
Faced with sea level rise and the intensification of extreme events, human populations living on the coasts are developing responses to address local situations. A synthesis of the literature on responses to coastal adaptation allows us to highlight different adaptation strategies. Here, we analyze these strategies according to the complexity of th...

Article
Preferences elicitation can be a challenging exercise for citizens participating in assessment surveys. It is even more challenging when it comes to complex and unfamiliar ecosystems and the threatened ecosystem services they provide. Making people aware of the characteristics of the ecosystem services being valued is determinant for the assessment...
Article
Satellite imagery is increasingly employed for land-use analysis and planning. In this article, we examine the economic value of high-resolution (HR) satellite images as perceived by direct users. Drawing on a French spatial-data infrastructure (SDI), the direct users of which are mostly from public bodies, we used a contingent-valuation method to...

Article
This paper examines to what extent the ecosystem services (ES) provided by coastal (near toMontpellier) or aquaculture ponds (in the Dombes region) contribute to the life satisfaction of local populations and of direct beneficiaries of these ES. This research is based on three face-to-face surveys and an online survey on a national scale, so as to...
Article
The attractiveness and urbanisation of coastal zones increase their vulnerability to climate change and sea-level rise, in particular to flooding and marine erosion. In the face of the projected increase in losses and damages, the anticipation and measures needed for adaptation involve physical, socioeconomic and political dimensions at different g...
Article
Full-text available
By the end of the 20th century, many of the coastal lagoons along the French Mediterranean coast showed insufficient water quality and degraded ecosystem states due to anthropogenic impacts. Among these, nutrient over-enrichment, resulting in eutrophication, has been a major concern. The EU Water Framework Directive (WFD) has initiated public actio...

Article
The recognition of a spatial data infrastructure (SDI), as a two-sided market, leads the way to an innovative approach for analysing the strategies used to bring two groups of users into interdependent markets. The literature derived from the recent industrial organisation is rich in theoretical models, aiming at the study of price structure and pr...
Article
Facing sea-level rise, scientists recommend adaptation measures to relocate the most vulnerable assets. This is of particular interest regarding coastal land use management issues. In order to address the acceptability of these measures, we use the choice experiment method to assess residents' preferences for different relocation policy measures th...
Article
The increasing number of coastal floods in recent years in France has resulted in the design of new adaptation principles for the most endangered coastal areas. The aim of the government is to reduce the vulnerability of these areas by relocating property and infrastructure. These measures have, however, come up against considerable opposition from...
Chapter
The babassu (Attalea speciosa Mart. ex Spreng.) is a palm native to the Amazonian rainforest. It is very useful to mankind and is the subject of extractivism by local people: settlers, Quebraderas de coco babaçu, Quilombolas and indigenous peoples. Multiple uses have been recognized and result in the harvesting and processing of products from babas...
Chapter
The babassu palm tree (Attalea speciosa Mart. ex Spreng.) is a species native to the Amazonian rainforest. The invasive nature of this palm tree results in a high density of babassu palm trees with a subsequent decrease in forage crop production. This is a serious problem for local farmers who have tried to resolve it by removing mature palms, seed...

Languedoc-Roussillon, one of the largest sandy bays in Europe, is particularly vulnerable to the risk of marine inundation resulting from climate change. This article assesses the damage, in terms of lost beach surface by 2100, according to different adaptation scenarios: individual (denial, laisser-faire) or planned (strategic retreat). Two contin...
Article
Sea-level rise due to climate change creates new risks of submersion in coastal areas that must be taken into account. Although these are long-term risks for 2100, it is important to anticipate possible consequences in order to identify the most vulnerable areas or issues and develop the appropriate adaptation policies. The aim of this paper is to...
