Forest cover mapping is an essential tool for forest management. Detailed maps, characterizing forest types at a régional scale, are needed. This need can be fulfilled by médium spatial resolution optical satellite images time sériés. This thesis aims at improving the supervised classification procé...

Islands are the first to be affected by climate change (CC): their small size, generally low altitudes and external dependence increase their vulnerability to natural, particularly coastal hazards, aggravated by CC (Bertrand and Richard, 2011). Nowadays, the introduction of adaptation to CC is criti...

national audience The work presented in this paper focuses on the development of a very low-cost hardware and software solution enabling, through low-speed network infrastructures, the multiplication of long-range, reliable, robust (therefore amarino) sensors, autonomous, miniature, discrete, to wor...

Many Europeans know Europe only through high-profile competitions such as the European Football Championship or the Champions League. These sports events are among the most viewers in the world. But European football also makes it possible to see ‘business’ or ‘drift’ that is equally publicised (cor...

, located south of Loire-Atlantique, around 10 kilometres from Bourgneuf-en-Retz Bay, the remains of the Machecoul Castle are installed on a slight calcareous depression. In the Middle Ages, the fortress was placed on the southern confins of Brittany, close to the coastline and Falleron, a river tha...

The coastline is a very popular area that is facing increasingly frequent attacks in front of the sea, leading to a backsliding of the coastline. Almost a quarter of the French coastline is subject to erosion. Faced with this phenomenon, the majority of municipalities use a method of combating erosi...

Fishing is one of the most important socio-economic activities in the Mediterranean and particularly in the Maghreb. In Algeria, in recent decades it has become a leading employment sector for a large part of the coastal population. Exploitation of the sea is also one of the main animal protein reso...

International audience Climate change is a major issue for the wine industry. Climate and in particular temperature plays a key role in vine physiology and phenology. Temperatures can be highly variable inside a winegrowing region and they are strongly related to local environment (topography, water...

The environment in which companies operate changes (stagnating markets, stronger competition, increasing environmental pressure, increasing costs, particularly transport costs, etc.).These changes encourage firms to adopt new strategies in managing their flows. The professional press is increasingly...

The work on knowledge and operation is rare, as the latest work on this cave is very old. This situation hampers the current work. To carry out our work, we looked at the external morphology of the cave. The finding shows a gondolated morphology reflecting the presence of small dolines, which allow...

An analysis of the characteristics of elected representatives of French municipalities according to their proximity to the Mediterranean on the basis of secondary processing of data from the National Repository of Elected Representatives (2010) shows that, the closer to the Mediterranean coast, the...

The Cerrado and Atlantic forest biodiversity hotspots have been experiencing rapid land-use changes in the last five decades resulting in habitat fragmentation, invasion of exotic species and biodiversity loss. Herbivore mammals are a key community to investigate the impacts of land-use changes on b...

The Garifuna, the products of the conflict between Africans and indigenous Caribes during the colonial period, have been living since the 18th century on the Caribbean coastline of four Central American countries (Belize, Guatemala, Honduras and Nicaragua). Following a steady migration process that...

This article describes a Geographical Data Infrastructure (Indigeo) developed in an academic framework involving a research laboratory and several environmental observatories. The deployed solution, based on free tools, is based on a metadata catalogue and a geo-referenced data server, backed by a w...

This paper examines the specificity of the coastline as a natural, cultural and medial boundary and interface. It focuses on how the motif of the coastline is depicted and remediated in the works of English artists Paul Nash and Dave McKean: between 1919 and 1925, as he was coming to terms with the...

International audience Agricultural intensification has greatly decreased grassland surface area in some regions, thus changing grassland management and modifying environmental and socio-economic systems. Therefore, knowledge about grassland management practices in farming systems is needed for sust...

This will not be so much an answer — which, necessarily nuanced, would have nothing original — to the question of the historical reliability of hagiographic stories, but to present a small sample of extracts from Anglo-saxon worms; stress, after rapid stripping, what their originality owes to the ex...

During the 1930s, Great Depression, repeated droughts, dust storms and erosion weakened farmers in the Great Plaines. More than two million will leave their farms for California. It was this social, economic and climate phenomenon that the American painter Alexandre Hogue chose to paint in a series...

Industrial ecology includes a set of practices aimed at reducing polluting industrial discharges and stands today as a possible way for the transition of industrial system towards a more sustainable operating mode, inspired by natural ecosystems. Its implementation can also be at the origin of innov...

This work aimed at providing a better understanding of nearshore circulation and dispersion processes under the effect of waves. An operational numerical modeling tool was developed, based on the spectral wave model WAVEWATCH III and the 3-D hydrodynamical model MOHID Water. The MOHID implementation...
