Fishing resources: catches and food availability
Fishing resources: catches and food availability By Julien NOËL L'Atlas Bleu / Exploiting Fishery resources, fishery, food fish consumption, disparity, world A map established on a global scale allows to compare the per capita food fish consumption by country and the fisheries catches of the adjacent ocean areas. North-South and inter-continental global disparities are highlighted and commented, revealing deep global imbalances in access to fishery resources. Fishery catches by FAO area and seafood food availability by country (interactive map)
Habitat vulnerability to coastal flooding risks. The example of L’Épine (Vendée, France)
Habitat vulnerability to coastal flooding risks. The example of L’Épine (Vendée, France) By Axel CREACH, Elie CHEVILLOT-MIOT and Denis MERCIER L'Atlas Bleu / Living Marine submersion, housing exposure, hazard, Xynthia, L’Epine, Vendée Based on the example of a municipality of the Noirmoutier island (Vendée), the article examines the vulnerability of housing to the risk of marine submersion of the Xynthia storm type, in a context of coastal urbanisation in low-lying areas. The cartographic synthesis allows to compare the potential water level and the architectural character of each construction, and to determine
Clandestine migrations in the Gulf of Guinea, non-native fishing camps on the Gabonese coast and in the Akanda National Park
Clandestine migrations in the Gulf of Guinea, non-native fishing camps on the Gabonese coast and in the Akanda National Park By Chancia NYINGUÉMA and Patrick POTTIER L'Atlas Bleu / Living Clandestine migration, foreign fisher, Gabonese coast, Akanda National Park The article describes clandestine maritime migrations at the scale of the Gulf of Guinea, and analyses the relationship with fishing communities practices through the examples of the Gabonese coast and the Akanda National Park. Indeed, the structuring and expansion of artisanal fishing practices in these areas favors the creation and settlement of

Vulnerability of Ivory Coast beaches to erosion
Vulnerability of Ivory Coast beaches to erosion By Célestin HAUHOUOT, Philibert KOFFI, Patrick POTTIER L'Atlas Bleu / Living Ivory Coast, coastal erosion, destroyed building, precariousness of the population, sector from Grand-Lahou to Assinie After highlighting the main physical characteristics of the Ivorian coastline on a national scale and proposing a typology of the sensitivity of its coastlines to erosion, the article examines the problem of coastal hindsight according to the point of view of the vulnerability of inhabited places. Several local examples are studied, showing the scope of the damage
Natural marine and coastal risks worldwide
What are the major natural risk the coastal zones cope at a global scale? What are their main drivers? The aim of this article is to propose a synthetic analysis and mapping of the different types of risks that occur in coastal zones.
Natural and anthropogenic hazards in tropical seas
This article proposes a synthetic visualisation of the risks weighing on the world intertropical zone. The interactive version of the map brings food for thought on each issue.

Marine invertebrates introduced into the Normano-Breton Gulf since 1920 By Laurent GODET, Patrick LE MAO, Eric THIÉBAUT, Christian RETIÈRE, Louis CABIOCH, Franck GENTIL, Nicolas DESROY, Jérôme FOURNIER L'Atlas Bleu / Protecting Maritime invertebrate, faunistic inventory, species, Normano-Breton Gulf The article has anticipated the publication of the ‘Atlas de la faune marine invertébrée du golfe Normano-Breton’ (see bibliographic reference). This article presents a synthesis of two centuries of observation and inventory of 2,152 species located in the Gulf. Several examples deal with the non-native species introduction in the marine area, and
Developing port infrastructures and protecting natural heritage in Veracruz (Mexico)
Developing port infrastructures and protecting natural heritage in Veracruz (Mexico) By Loïc MÉNANTEAU et Stephan GAILLARD L'Atlas Bleu / Protecting Bathymetry, sediment budget, port, environment, national park, Gallega (La), Veracruz, Vergara (Bay of). This article presents the main development stages of the port of Veracruz (Mexico), an historic site located on the edge of a protected reef system. A digital terrain model (DTM) allows to follow its transformation (embankments on the sea, dredging, infrastructures) on three dates (1886, 1911, 2010), mainly since the big works leaded from 1887 to 1902.
Professional fishing and the risk of accidents: the Dover Strait, an example of a high risk area
Professional fishing and the risk of accidents: the Dover Strait, an example of a high risk area By Brice TROUILLET L'Atlas Bleu / Exploiting Maritime fishing, spatial division, risk, accident, Strait of Dover. At the world scale, the Strait of Dover is a highly-concentrated area of the maritime activities (shipping and passenger traffic to name a few). The article examines the case of fisheries in this context, namely the risks fishers face day-to-day in an increasing congested sea. Fishing is one
