Mediterranean soil resources are heavily affected by water erosion. There is a need for anticipating the potential impact of land-use change at the catchment scale, considering a range of contrasted possible changes, in order to prepare a relevant adaptation strategy. While participatory scenario approaches are useful for unveiling the diversity of possible futures, their outputs generally take the form of narratives that may be difficult to relate to biophysical models used for simulating soil and water processes. We addressed this challenge by developing a methodology combining narrative scenarios and land-use change modelling at the catchment scale, interacting with local stakeholders who were involved throughout the research, in line with current Land System research. First, we built contrasted scenarios, each with a narrative story and quantitative assumptions for key variables. Then we drew up rules for translating narrative scenarios into spatially explicit maps based on expert groups and local knowledge, simulating the evolution of land use over time. Third, we evaluated and validated the final scenarios by conducting two workshops with scientists and local stakeholders. Finally, we assessed the impact of these scenarios on agricultural production and erosion control. This approach was implemented in the Tleta basin (Morocco), a 180 km2 rural watershed, 10 km from Tangiers and heavily affected by water erosion. As a result, we propose three contrasted spatially explicit land-use change scenarios by 2040. Our work highlights the interest of combining narrative storylines and land-use modelling when developing spatially explicit scenarios at the catchment scale, incorporating the local knowledge of stakeholders. The combination of Land System and ecosystem frameworks contributes to integrating the soil erosion issue in a more global perspective, and lays the foundation for building sustainable strategies for Mediterranean catchments affected by soil erosion.

Nature-based solutions (NBS) are increasingly being promoted as a means to address societal and environmental challenges, especially flood risk reduction. In the context of rapidly urbanizing catchments, NBS can take part of the development of sustainable cities, either by conserving peri-urban ecosystems from urban sprawl or by developing green infrastructure in the cities. Both can provide a wide range of co-benefits (e.g., climate regulation, air quality regulation), but also generate some negative effects (e.g., mobility issues, unsafety, allergens). We develop and implement a Discrete Choice Experiment survey to analyse people’s perception of co-benefits and negative effects, and associated preferences for the two types of NBS at a catchment scale. The results obtained from 400 households living in a French Mediterranean catchment highlight that people associate numerous co-benefits to NBS, but also negative effects. Our estimations reveal that resident households are ready to contribute large amounts through a tax increase for the development of NBS (from 140 to 180 EUR/year, on average). There is however a strong heterogeneity of preferences at the catchment scale influenced by income, location of the respondent along an urban–rural gradient, and perception of the importance of ecosystem services. These differences may reflect urban environmental inequalities at the catchment scale, which are important to take into account in order to avoid distributive inequalities.

The objective of this study was to examine the impacts of climate and land use changes on water availability and sediment loads for a water supply reservoir in northern Morocco using data-intensive simulation models in a data-scarce region. Impacts were assessed by comparing the simulated water and sediment entering the reservoir between the future period 2031–2050 and the 1983–2010 reference period. Three scenarios of land use change and two scenarios of climate change were developed in the Tleta watershed. Simulations under current and future conditions were performed using the Soil and Water Assessment Tool (SWAT). The simulations showed that climate change will lead to a significant decrease in the annual water supply to the reservoir (16.9% and 27.5%) and in the annual volume of sediment entering the reservoir (7.4% and 12.6%), depending on the climate change scenarios tested. The three scenarios of land use change will lead to a moderate change in annual water inflow into the reservoir (between −6.7% and +6.2%), while causing a significant decrease in sediment entering the reservoir (−37% to −24%). The combined impacts of climate and land use changes will cause a reduction in annual water availability (−9.9% to −33.3%) and sediment supplies (−28.7% to −45.8%). As a result, the lifetime of the reservoir will be extended, but at the same time, the risk of water shortages will increase, especially from July to March. Therefore, alternative water resources must be considered.

This paper demonstrates the usefulness of valuing a diversity of ecosystem services for groundwater protection. It argues that improving the understanding of local stakeholders regarding the benefits that strategic groundwater preservation for future generations can bring to their territories is a relevant mean to enhance their support towards groundwater conservation. We develop and test a systemic approach based on local data collection, cost-based monetary valuation methods and stakeholder involvement. The paper reports on empirical work conducted in a strategic groundwater area located in Southern France, that could be of interest in the future to supply the growing population of coastal urban areas. We characterize, quantify and valuate in monetary terms nine ecosystem services. We then analyze the perception of the proposed approach, ecosystem services and associated monetary values by organising a workshop involving 25 local stakeholders. Overall, participants validate the operational feasibility and the relevance of the approach for raising awareness and bridging the gap between environmental issues, which can be effective triggers to the implementation of protection action. Yet, monetary valuation provides only partial insights into the overall value of the benefits of protecting the strategic groundwater area, and would improve from being articulated with socio-cultural valuation methods.

This article proposes an innovative approach to assess the benefits of adapting to sea level rise (SLR) in a coastal area on a regional scale. The valuation framework integrates coastal ecosystem services, together with urban and agricultural assets. We simulate the impacts of a progressive 1 m rise in sea level in the twenty-first century and an extreme flooding event in 2100 for four contrasted adaptation scenarios (Denial, “Laissez-faire”, Protection and Retreat). The assessment involves coupling the results of hazard-modelling approaches with different economic valuation methods, including direct damage functions and methods used in environmental economics. The framework is applied to the French Mediterranean sandy coastline. SLR will result in major land-use changes at the 2100 time horizon: relocation or densification of urban areas, loss of agricultural land, increase in lagoon areas and modification of wetlands (losses, migration or extension of ecosystems). Total benefits of public adaptation options planned in advance could reach €31.2 billion for the period 2010–2100, i.e. €69,000 per inhabitant (in the study area) in 2010 or €135 million/km of coastline. Our results highlight the importance of (i) raising awareness to ensure that public services and coastal managers can anticipate the consequences of SLR and (ii) incorporating coastal ecosystems into the assessment of the adaptation options. Our findings could provide a basis for participatory foresight approaches to build coastline adaptation pathways.

Le Languedoc-Roussillon, une des plus grandes baies sableuses d’Europe, est particulièrement vulnérable au risque de submersion marine lié au changement climatique. Cet article évalue les dommages, en termes de surface de plage perdue, à l’horizon 2100, selon différents scénarios d’adaptation, individuelle (déni, laisser-faire) ou planifiée (recul stratégique). Deux évaluations contingentes fournissent la valeur de la fonction de protection des plages vis-à-vis des tempêtes et de leur fonction récréative. Ces valeurs, par hectare de plage, sont centrales pour les politiques d’aménagement.

The transcription of the 2000’s European Water Framework Directive in France has led to define maximum volumes that can be abstracted in water bodies. In many French contexts, it requires reducing more or less drastically current water consumption, especially in agriculture where farmers were granted permits by the water policy authority, regardless the real level of water availability. To do so, French water law imposes, where water bodies are structurally in water scarcity, to create irrigation associations charged to share available water between farmers. And the challenge is particularly high in the groundwater case, where farmers are not embedded in collective irrigation schemes. Sharing rules have then to be designed from the ground up. This communication presents and critics the way that innovative management instruments were explored in six cases’ studies representative of the diversity of agricultural products and hydrogeological situations. These instruments were debated during 18 foresight workshops held with institutional representatives (50) and farmers (87). Foresight workshops had the advantages to make credible institutional and resource changes, and to retrieve from current but side-debates. In five cases, researchers took the lead of these workshops, and in the last one it was directly carried by a stakeholder (an Agriculture Chamber), which allows to test the transferability of such a method in real context with a direct implementing goal. Lessons are drawn at several levels. Firstly, debating on contrasted scenarios is a robust way to facilitate discussions on something not implemented yet in France. Secondly, the context highly matters, in particular the perception of the reality of groundwater scarcitylevel. Thirdly, to debate on groundwater management tools has to be firstly embedded in a more general discussion, on the future of agriculture or at least on more broadly water challenges (like in terms of quantity and quality).

This chapter investigates the potential and limits of the contingent valuation method for assessing the benefits of groundwater remediation or protection programs. The discussion is based on a review of the literature and on two original contingent valuation surveys conducted in France and in Belgium, in contexts where groundwater was expected to be particularly unfamiliar to respondents. Particular attention was paid to (i) people’s perception and understanding of the resource under study, and (ii) type and quantity of information provided by the questionnaire. In both cases, we show that the population is concerned about groundwater remediation or protection, especially to guarantee the wellbeing of future generations. Overall, we highlight that assessing willingness to pay through contingent valuation surveys is helpful for conducting an integrated valuation of groundwater protection benefits. However, we also point out two main limits which might restrict the relevance of the results obtained: (1) the respondents’ limited prior knowledge of groundwater and the risk that information provided by the questionnaire biases the elicitation process; and (2) two types of embedding effect, with the difficulty for respondents in considering the geographic extension of an aquifer and disentangling benefits derived from groundwater quality improvement from other environmental benefits.

Beach protection has become a major issue in reducing coastal risks (erosion and flooding). It is thus advisable to study residents’ preferences for mitigation strategies. Willingness-to-pay (WTP) by permanent and secondary residents for flood protection provided to properties by Languedoc-Roussillon beaches (French Mediterranean coast) is investigated by a contingent valuation study. Results show that WTP is more influenced by risk perception variables than by socio-economic ones. The WTP is then extrapolated on the basis of different adaptation strategies (laissez-faire, managed retreat, denial etc.) which provided information about expected damage associated with sea level rise at the 2100 time horizon.

International audienceIn Europe, 30% of groundwater bodies are considered to be at risk of not achieving the Water Framework Directive (WFD) 'good status' objective by 2015, and 45% are in doubt of doing so. Diffuse agricultural pollution is one of the main pressures affecting groundwater bodies. To tackle this problem, the WFD requires Member States to design and implement cost-effective programs of measures to achieve the 'good status' objective by 2027 at the latest. Hitherto, action plans have mainly consisted of promoting the adoption of Agri-Environmental Schemes (AES). This raises a number of questions concerning the effectiveness of such schemes for improving groundwater status, and the economic implications of their implementation. We propose a hydro-economic model that combines a hydrogeological model to simulate groundwater quality evolution with agronomic and economic components to assess the expected costs, effectiveness, and benefits of AES implementation. This hydro-economic model can be used to identify cost-effective AES combinations at groundwater-body scale and to show the benefits to be expected from the resulting improvement in groundwater quality. The model is applied here to a rural area encompassing the Hesbaye aquifer, a large chalk aquifer which supplies about 230,000 inhabitants in the city of Liege (Belgium) and is severely contaminated by agricultural nitrates. We show that the time frame within which improvements in the Hesbaye groundwater quality can be expected may be much longer than that required by the WFD. Current WFD programs based on AES may be inappropriate for achieving the 'good status' objective in the most productive agricultural areas, in particular because these schemes are insufficiently attractive. Achieving 'good status' by 2027 would demand a substantial change in the design of AES, involving costs that may not be offset by benefits in the case of chalk aquifers with long renewal times

MISEEVA (2008-2011) aims to assess coastal zone vulnerability to marine inundation by integrating the physical and socio-economical aspects at different temporal (2010, 2030 and 2100) and spatial (local to regional) scales. The Languedoc Roussillon (France) region was chosen as a pilot site, focusing on local sites from Villeneuve-lès-Maguelone to Carnon, in Hérault. It required the development of a transdisciplinary methodology to enable transfers of knowledge and promote interdisciplinary iteration of methods throughout the project. In 2030, sea level rise (SLR) should not exceed 0.07m (IPCC, 2007). For 2100, SLR of 0.35m (A2 SRES scenario, GIECC 2007) and 1m (Rahmstorf, 2007, Grinsted et al, 2009), are both considered. As negligible changes in storminess are expected (IPCC, 2007, Déqué, 2007), historical storms are therefore used as references to simulate exceptional inundations, in 2010, 2030 and 2100. Regional and local propagation of wind-generated waves and surges (wave set-up and atmospheric surge) are calculated using a chain of models and semi-empirical formulas. Then, maps of permanent, recurrent and exceptional inundations (due to SLR, tidal level, and surges) in 2010, 2030, and 2100 are drawn. Socio-economy in 2030 is believed to follow the present day trend in Languedoc-Roussillon (demographic growth, urbanisation and tourist development). Socio-economic evolution in 2100 is quite unforeseeable: scenarios for 2100 are being built based on contrasted potential adaptation strategy scenarios Designing a typology and valuation of present day assets help to value potential damages processes due to marine inundation on the coastal system at 2010, 2030 and 2100. Perception and response capacity knowledge to marine inundation risk is gained through residents, users and stakeholder surveys at the local site. Mixing physical and socio-economical approaches to evaluate the exposure of a territory to a hazard allows progression towards a systemic definition of vulnerability. Projection in the future points out the need to consider adaptation capacity as a main parameter of vulnerability evolution.

Cet article propose un cadrage méthodologique d’évaluation économique ex-ante des programmes de mesures à mettre en œuvre, conformément aux exigences de la Directive Cadre sur l’Eau, à l’échelle d’un bassin hydrographique. La préparation du 9ème programme d’interventions des Agences de l’Eau ainsi que du Schéma Directeur d’Aménagement et de Gestion des Eaux (SDAGE) visant à l’atteinte du bon état de l’ensemble des masses d’eau d’ici 2015 s’appuie sur une analyse coût-efficacité des mesures à mettre en place. La démarche consiste (i) à réaliser une typologie de mesures correspondant aux principaux enjeux de gestion de l’eau du bassin ; (ii) à évaluer des coûts d’ordre pour chaque type de mesure ; (iii) à dimensionner la mise en œuvre des mesures sur l’ensemble des masses d’eau ; (iv) puis à évaluer et comparer les ratios coût-efficacité des combinaisons de mesures proposées. L’application de ce cadrage méthodologique à l’enjeu de lutte contre la pollution organique des eaux superficielles du bassin hydrographique Rhin-Meuse donne un premier chiffrage des coûts de mise en œuvre des mesures nécessaires à l’amélioration de l’état des cours d’eau du bassin. Alors que le coût moyen annuel des mesures réglementaires actuellement en vigueur ainsi que des travaux déjà engagés (mesures de base) est de l’ordre de 70 millions d’euros par an, le programme de mesures complémentaires proposé pour l’atteinte du bon état entraînerait un coût moyen annuel de 88 millions d’euros, correspondant à une réduction des rejets de matières organiques sur les masses d’eau à risque de 70%. The aim of this paper is to propose a methodological framework to carry out the ex-ante economic assessment of the program of measures needed for the implementation of the Water Framework Directive (WFD) at the river basin scale. A cost-effectiveness analysis of potential measures has to be carried out in order to prepare the 9th French Water Agencies program and the river basin water planning and management scheme (SDAGE) that will be implemented to reach the good ecological and chemical water status until 2015. The main methodological steps are: (i) development of a typology of measures that could be implemented for the main water management issues of the river basin; (ii) assessment of a reference unit cost value for each of these measures; (iii) planning and selection of the scale for the implementation of measures; (iv) cost-effectiveness analysis and comparison between several combination of measures. The methodological framework has been used for a concrete economic assessment of the implementation of measures to reduce organic pollution in the French Rhine-Meuse surface water bodies. The mean annual cost of regulations and current measures (basic measures) has been estimated at 70 million euros per year for the whole Rhine-Meuse basin. In addition , supplementary measures necessary to reach the good status would cost 88 million euros per year and lead to a 70% decrease in the level of organic matter discharged into surface water bodies at risk.
