Winner of the second wave of the call for project Laboratory of Excellence (Labex) in the framework of the "Future Investments", LabEx DRIIHM, device Interdisciplinary Research on Men-Media Interactions, brings together men-Observatories media (OHM, 8 in number) and their network (ROHM) which are a tool that the CNRS-INEE created since 2007. LabEx was set up for 8 years (February 2012-December 2019) with an allocation of 6.5 million Euros.

OHM Bassin Minier de Provence

The Gardanne mining area is the study area of this observatory.

Located in the east of the department of Bouches-du-Rhône, between Marseille and Aix-en-Provence, it concerns bringing together seventeen towns just over 100,000 inhabitants. For nearly two centuries, the unity of this space has been built around the lignite mining and industrialization induced by the mine. Bordered to the north by the massif of the Sainte-Victoire and the south by the Star chain as well as the mountain of Regagnas, iconic landscapes of Provence, this area is typical of suburban and industrial dynamics in the Mediterranean area. These dynamic, often contradictory, have been particularly affected by the permanent cessation of mining in the early 2000s.

Estarreja OHMI

Located in northern Portugal, the municipality of Estarreja is the study area for this OHM.I. It derives its originality of the presence of the second largest complex chemical country mainly producing ammonium sulphate, nitric acid and ammonium nitrate, but also synthetic resins (PVC), and its location near the largest brackish water lagoon of Portugal, the Ria of Aveiro.

Subjected to intense industrial pollution since the early 1950s, this area has suffered the simultaneous effects of solid waste, liquid and gas in the environment, which have both affected some plant and animal organisms and raised questions about health local populations.

OHM Littoral méditerranéen

Observation and research conducted by this OHM concern the Mediterranean coast of France, studied at three sites across a wide component gradient of urbanization and human pressure. The urbanizing at least subject to human pressures, these sites are: the Marseille urban area at large, from the docks of Fos-sur-Mer in the west to La Ciotat in the East; the gulf of Aigues-Mortes, Sète Grau du Roi, including coastal lagoons and associated watersheds; the shores of Balagne and the southern outskirts of Bastia, in Corsica. Spaces and environments studied correspond to the interface between the marine and terrestrial areas, that is to say the shore but also terrestrial and marine areas that infl uence each other on either side of the coastline, both ecological planning, hydrological or societal.

OHM Vallée du Rhône

The geographical area of OHM Rhone Valley is the river route from Lake Léman to the Mediterranean, the river itself, its appendices aquatic and riparian, floodplain for some. The study areas are thus subject to the influence of many amenities found throughout the river. These result of two key periods: the construction of the waterway (1840-1910) and the development of hydro-electric equipment (1948 to 1986). They have conditioned the evolution of contemporary landscapes and the distribution of human activities. A particular type of landscape characterized by Rhône "shorted," a channel and all associated works, repeats itself as a territorial pattern at each hydro development allowing unprecedented geographic comparisons and highlighting causality change.

OHMI Téssékéré

Located in the Ferlo, northern region of Senegal, the area studied by the OHM.I Tessékéré is characteristic of the African Sahel. This large area of bioclimatic transition between the Saharan area north and south Sudan savanna is characteristic consecutive ecological and human crises to drought events affecting Africa for several decades. The region covered by the Observatory presents all the traits specific to Sahel (rainfall deficit, human pressure on the environment, modification of the environmental equilibrium) and the distinction of being the heart of a major pan-African program development and reforestation called Great Green Wall.

OHM Oyapock

The human-environments observatorie Oyapock, created by the CNRS in 2008, is to project the long-term monitoring of relations human-environments in the valley of Oyapock border river of Guyana and Brazil.

Its implementation is related to the construction of the bridge linking the French and Brazilian sides of the river between the towns of Saint-Georges de l'Oyapock, french side and Oyapock, brazilian side. Its mission is to understand the parameters that affect the human population and the environment in connection with this event, and thus help in decision-making and public action.

The OHM Oyapock is part of the network of OHMs, itself integrated with the DRIIHM,Device for Interdisciplinary Research on human-environments Interactions.
