Aedes -borne diseases, such as dengue, chikungunya and Zika are caused by viruses transmitted by Aedes aegypti and Aedes albopictus , producing an enormous public health burden and a lesser-known economic impact. We present a reliable, up-to-date, standardized and easily updatable global-scale synthesis of studies reporting the economic costs cause...

In this paper, we examine a particular case of land use pattern: forest management activities facing an uncertainty related to spatial information signals received. We investigate the combination of two well-known theoretical approaches, the Blackwell theorem and entropy analysis, in providing a decision support framework for decision makers. We ex...

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...

In addition to being a major threat to biodiversity and ecosystem functioning, biological invasions also have profound impacts on economies and human wellbeing. However, the threats posed by invasive species often do not receive adequate attention and lack targeted management. In part, this may result from different or even ambivalent perceptions o...

The management of invasive alien species (IAS) is complex and requires consideration of intertwined ecological and economic dimensions. Given the wide variety of costing purposes and practices, and the associated risk of misunderstandings and/or miscommunication of their impacts which may jeopardize perceptions and management, there is an urgent ne...

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...

The development of integrated management policies in the coastal and maritime environment involves renewing the information systems in support of these policies. New indicators have been proposed for which it is necessary to study not only the methods of construction but also their legitimacy and the nature of the needs they meet. This article exam...

Cet article propose un cadre d'évaluation des impacts économiques des Infrastructures de Données Géographiques et Spatiales (IDGS), à partir de l'exemple de GEOSUD et des cartes de coupes rases relatives à la gestion des forêts. L'évaluation est réalisée à partir d'une enquête en ligne auprès des services de l'État chargés du contrôle des coupes ra...

Biological invasions are responsible for substantial biodiversity declines as well as high economic losses to society and monetary expenditures associated with the management of these invasions1,2. The InvaCost database has enabled the generation of a reliable, comprehensive, standardized and easily updatable synthesis of the monetary costs of biol...

The Asian tiger mosquito is an invasive species, present in France for two decades, which is responsible for significant nuisances and can transmit serious diseases. We use DCE and CVM to value the reduction of these nuisances and health risks, and to estimate WTP for prevention and control measures. Our results show that populations are firstly se...

Economic valuation has been presented as an important tool for enhancing the consideration of ecosystem services (ES) in decision-making. Recent literature provides evidence that an implementation gap between theoretical findings, consideration in the policy sphere, and measurable action in practice persists. Our paper aims to contribute to its clo...

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...

This paper aims to investigate the extent to which ecosystem services maps can improve land-use planning decisions by strengthening the consideration of environmental issues. The methodology used is based on an experimental workshop simulating a participatory decision-making process for planning choices by a panel of territorial actors. The protoco...

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...

Since its accidental introduction in 2003 in France, the yellow-legged Asian hornet Vespa velutina nigrithorax is rapidly spreading through France and Europe. Economic assessments regarding the costs of invasive species often reveal important costs from required control measures or damages. Despite the rapid invasion of the Asian yellow-legged horn...

Ce chapitre propose un parcours dans un domaine qui a fait couler beaucoup d’encre depuis une dizaine d’années : celui de l’association d’une valeur économique aux avantages que nous procure la nature. La question est beaucoup plus ancienne, mais elle a suscité beaucoup d’interrogations depuis qu’elle a pris de l’importance dans le champ institutio...

Between ecological integrity and economic efficiency: analysis of a "ecological no net loss" Policy. Defining and implementing a policy of no net loss of biodiversity raise many questions of an ecological, economic and social nature. In this article, we propose to analyze three of them from an economic perspective at the crossroads of ecological an...

The ecosystem approach to aquaculture (EAA) considers ecosystem services (ES) important, but does not provide a framework for them. To supplement the EAA, a literature review of the ES conceptual framework and ES typologies was combined with selected criteria from the EAA and ES literature. The selected criteria to decide on a conceptual framework...

L'objet de cet article est d'analyser les impacts socio-économiques d'Infrastructures de Données Spatiales (IDS) basées sur l'imagerie satellitaire dans les politiques publiques environnementales, agricoles et territoriales. Nous nous appuyons pour cela sur le cas de l'IDS de l'Equipex GEOSUD à la Maison de la Télédétection à Montpellier. Après une...

From an economic perspective, damage and loss valuation aims first at justifying climate change mitigation efforts. But the difficulties related to the heterogeneity of the damage and the time horizon of the impacts make the results very contingent of the computation hypotheses. The debate thus focused on the social cost of carbon, driven by the id...

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...

We investigate whether visitors’ preferences for recreation and conservation could be reconciled by identifying management tradeoffs. We use a choice experiment based on a random sampling, and conducted face-to-face interviews on site with 475 respondents. Improving biodiversity emerged as the action with most likely effect of increasing the welfar...

Background REDD+ is being questioned by the particular status of High Forest/Low Deforestation countries. Indeed, the formulation of reference levels is made difficult by the confrontation of low historical deforestation records with the forest transition theory on the one hand. On the other hand, those countries might formulate incredibly high de...

Using a classification of existing approaches in environment economics and ecological economics, this article presents a method of valuing ecosystem services based on perception surveys. It assesses, on one hand, the level of familiarity with services among a diverse array of stakeholders, citizens and/or service users- and, on the other hand, appr...

RAPPORT SCIENTIFIQUE DE L'ÉTUDE RÉALISÉE PAR L'INRA - NOVEMBRE 2017

While high resolution spatial variables contribute to a good fit of spatially-explicit deforestation models, socio-economic processes are often beyond the scope of these models. Such a low level of interest in the socio-economic dimension of deforestation limits the relevancy of these models for decision making and may be the cause of their failure...

The land sparing versus land sharing debate has already had a significant history and was particularly active during the last decade. Studies carried out mostly by ecologists and agronomists have clarified a number of issues related to best land use strategies in different landscapes; establishing that the best strategy depends first on the respons...

Tropical forests of the Guiana Shield are the most affected by gold-mining in South America, experiencing an exponential increase in deforestation since the early 2000's. Using yearly deforestation data encompassing Guyana, Suriname, French Guiana and the Brazilian State of Amapá, we demonstrated a strong relationship between deforestation due to g...

Significations, intérêts et limites des approches économiques de la valeur de la biodiversité

Most of the world’s wild flowering plants (87.5%) are pollinated by insects and other animals (established but incomplete), more than three quarters of the leading types of global food crops can benefit, at least in part, from animal pollination (well established) and it is estimated that about one-third of global food volume produced similarly ben...

Pollinators provide a wide range of benefits to humans, such as securing a reliable and diverse seed and fruit supply, underpinning wider biodiversity and ecosystem function, producing honey and other outputs from beekeeping, and supporting cultural values. These benefits can be expressed in economic terms to quantify the consequences of gains a...

Insects have presented human society with some of its greatest development challenges by spreading diseases, consuming crops and damaging infrastructure. Despite the massive human and financial toll of invasive insects, cost estimates of their impacts remain sporadic, spatially incomplete and of questionable quality. Here we compile a comprehensive...

Les écosystèmes humains n’ont pas seulement une valeur en eux mêmes, ils nous rendent aussi d’innombrables services. Or, la « nature » est menacée par les pressions qui s’exercent sur elle : changement d’usage des sols, pollution, changement climatique, etc. Dans ce contexte, l’évaluation économique a pour objet de révéler la valeur sociale de la n...

Natural areas contribute to human well-being in many ways. Among the ecosystem services provided by natural areas, recreational services appear increasingly valuable. The main objective of our study is to evaluate the recreation demand of the Sensitive Natural Areas (SNAs) in the Hérault Department (France). These areas are acquired to protect them...

Highlighting the value of natural areas is a key element of legitimation for the constraints their protection imposes on certain activities. Travel cost method is used to value the recreational activities of the Port-Cros National Park (France), the first marine Park created in Europe, and currently a marine and terrestrial natural protected area n...
