RepExtrem: Analysis and Mapping of heat waves in urban areas

Background and objectives

French meteorologist agency, Meteo-France, is producing maps resulting from the comparison of different forecast models in order to propose the most likely weather forecast. If models integrate data from a large special extend, urban areas are specific as they produce and store heats. Moreover that are sensitive places as they host a large proportion of people. As the city can be 10 degrees warmer than the surrounding countryside, as was the case in west Europe in August 2003. Furthermore, the climate change impact studies are still often limited to integrate the effects specific to the city. However a recent report (Ouzaeu et al 2015)[1] on possible scenarios for the next 100 years unfortunately confirms the risk of increased frequency of such phenomena on highly populated urban areas.

The research on Integrating Floods in Urban and Architectural Projects (PRÉCIEU) studies how flooding hazard is considered in urban projects, at neighbourhood scale. PRÉCIEU wants to have a particular regard for political strategies of middle-sized urban areas – based on the study case of French cities : Angers, Le Havre, and Narbonne – which choose to develop urban projects in established or presumed flood area. The PRÉCIEU positioning strategy is to shift the focus away from flood risk prevention and management to urbanism practice: this study will be focused on professions, tools and interests of spatial planning rather than on ‘best practices’ in flood risk prevention and management.

Elision but Inexorable Risk: what kind of resilience to soil pollution in former industrial areas?

EMIR research project takes the notion of resilience seriously and questions it from three perspectives: first, taking into account the slow temporal disturbances that affect an area and the answers given (or not) to these perturbations that will be analyzed in a comprehensive understanding of the economic and social dynamics system; secondly, by focusing on « very low profile » disturbances that are not subject to any mobilization or poorly legible, inefficient or even unrecognized mobilization (s) – the resilient character of a given area is often inferred from visible signs of change and adaptation to crisis phenomena that are just as visible – and finally, considering passive forms of resilience that lead to degraded situations and lead to question implicit reference to the « right » reaction and / or capacity of action.

The project aims to qualify how systems may adapt during the phase of disorder resolution (reparation, reconstruction, reorganization) which follows hazard occurrence. Adaptations taken into account are mainly those which imply sensitivity reduction of exposed assets (vulnerability reduction, assets relocation). Measures such as damage pooling (through insurance or solidarity), or hazard mitigation (in intensity or frequency) also impact the resilience of the territory but the analysis of their exact influence is out of the scope of this project.

Resilience of french overseas territories to coastal risks in the context of global change (Réunion Island, French Polynesia)

Five research laboratories contribute to the Réomers project: UMR LIENSs 7266 (geomorphology, environmental geography, geomatics; lead), Iddri (Sciences-Po Paris, human geography and law), CEJEP (University of la Rochelle, law), Géophen (LETG UMR 6554, Caen, geomorphology) and GEL (EPHE, Dinard, geomorphology). Additionally, two international experts are involved in this project, Andrew Cooper (University of Ulster) and John Hay (USP, Cook Islands). This project is also based on a close collaboration with both national institutions (ONERC, MEDDE) and local stakeholders, as it aims to support risk reduction (integrated shoreline management policy) and climate change adaptation (national plan for adaptation to climate change).

Resilience, how to make the concept operational ?

The research project RCO (for “Resilience, from Theory to Practice”), aims at improving the understanding of resilience as a concept used in practice by different types of risks practitioners (experts, engineers, researchers, risks managers, territorial managers) on the scale of a departmental territory. Our main objective is to understand how these specific actors (located in the French Département of Isère) concretely use the concept of resilience, and to identify if and how the issue of resilience might influence their practical work experience. Our project considers all kinds of risk (industrial, environmental, natural, health, etc.) existing on the territory of Isère.

Protective levees against flooding are large alignment structures that are critical for the safety of goods and people. In urban areas, it is common that these structures are used as mobility networks or are crossed by other technical networks. Read More →

Bringing Resilience into Changing Territories : Emerging risks management and territorial stakes in the South West region of France

This project aims at documenting the socio-territorial conditions at the centre of which resilience building takes shape in response to both weather-related and anthropogenic hazards in a global context of climate change and energy crisis. While the project conceptualises resilience as a reflexive process enabling the sustainability of social and institutional organisations to face inevitable changes, ACTER builds on the notion of territory as a way to identify contested sites of power through which interests collide over the use and meaning of the biophysical environment.

AEDES: Representation of hazards and definition of health risk related to the colonization of mainland France by Aedes Albopictus

Given the objective rise of health risks, related notably to dengue and chikungunya fever, which is due to the colonization of the coastal and seaside areas by tropical mosquitoes – that are potential vectors of a large range of diseases – in mainland France, it appeared to us crucial to better understand the multiple factors of vulnerability and resilience in the case of outbreaks, in particular the cognitive, social and behavioral ones, so that more effective and appropriate prevention policies targeting the exposed population might be developed in the next future.

Contribution to the Systemic Modeling of Technical and Organizational Resilience of a Territory to Natech Risk: from microscopic to macroscopic

Chemical accidents triggered by natural hazards (known as Natechs) are relatively rare. In fact they represent between 2 – 7 % of all chemical accidents reported in databases such as ARIA, MARS, FACTS, MHIDAS, NRC (Sengul et al., 2012; Rasmussen, 1995). Nonetheless, several studies indicate that Natech accidents are (Stacy Young et al., 2004; Sengul et al. 2012). Growing urban populations and industrialization in areas subject to natural hazards, coupled with environmental change due to climate change and other factors will contribute to an increase in the number of Natech accidents in the years to come (Ana Maria Cruz et al., 2004).
