The term agroforestry covers practices that are promoted to maintain or even enhance biodiversity. However, the relationship between agroforestry and invasive species is rarely addressed, even though the spread of such species is an important issue, not only ecologically but also economically and socially. Over the past few decades, humans have gre...

As the heritage of rural systems which have used the tree as a structuring element, landscapes with non-woodland trees are under threat and are rarely taken into consideration in public policies. Yet they are of environmental and political importance not only due to the problems and challenges they present but also because of their potential, namel...

Small farmers have been blamed for forest degradation in O'Valley, Gudalur. The state's response to this perceived forest degradation in the post-colonial period has been to increasingly environmentalise forest policy and law through extending its territorial control over the 'forested commons', consequently labelling farmers as encroachers. This a...
Article
Full-text available
The northern part of the Mediterranean Basin recently experienced major transformations. Landscapes evolved along two contrasting trends: agricultural intensification and urbanization in the plains, and disuse of marginal areas. This led to a gradual disappearance of the natural and cultural heritages associated with Mediterranean scrublands. To re...

Milieux changeants, instables, dangereux parfois, rudes souvent, les montagnes attirent pourtant, et ce depuis fort longtemps, des populations nombreuses. Leur anthropisation ancienne témoigne du vif intérêt qu'elles ont très tôt représenté pour les hommes et leurs activités. En plaçant au cœur de son sujet la notion de ressource, cet ouvrage propo...

La diversité des terroirs de moyenne montagne se trouve unie, fédérée par un élément omniprésent dans le paysage : il s'agit de l'arbre hors forêt, en dehors des bois et forêts. L'arbre hors forêt est partout, qu'il soit arbre épars, isolé au milieu d'une prairie ou sur la place d'un village, planté en alignement le long des routes, qu'il se trouve...

Trees outside forests are difficult to define and often seen as troublesome in areas were major crops are grown. They are nonetheless visible everywhere in French landscapes, to the extent that they do not always get the attention they deserve. The diversity of tree structures can however supply a range of economically viable resources. Furthermore...

Rural people in developing countries including India continue to access a number of types of ‘forests’ to meet specific needs such as fuelwood, fodder, food, non-timber forest produce and timber for both subsistence and income generation. While a plethora of terms exist to describe the types of forests that rural people use—such as farm forests, so...

"Decentralization policies around forest management in developing countries such as India have received a large amount of attention in the recent past. But invariably analysis has been limited to the specificities of policies and to what extent they have provided forest produce benefits or not to forest-dependent communities. Public policies around...

Le Kérala, (S-O de l'Inde) ne représente que 1,2% de la superficie du pays pour 3,4% de sa population. S'il est très peu peuplé par rapport à la moyenne indienne, il apparaît peu urbanisé. La hiérarchie urbaine s'y inscrit dans le cadre d'un habitat dispersé:les habitations sont sur des terres exondées et sur des plantations. Mais, le Kérala reste...

ANR JC JC – BENDYS (ANR-19-CE03-0010) Scientific evaluation committee CES 03 Human-Environment interactions BENDYS is an interdisciplinary project focusing on the last European Old-Growth Forests (OGFs) that brings together, for the first time, researchers in Humanities and Social Sciences (sociology, anthropology, archaeology, history, geography) and in Environment and Life Science (ecology, biogeochemistry, geology, biology). The project is focusing on the last European old-growth fir-beech forests that are today threatened by global warming, unsustainable uses and a lack of global conservation plans. The major issue for their better understanding and conservation is to accurately define their reference state. To tackle this issue, we must study long-term legacies and ongoing impacts of anthropogenic and natural drivers on the structure, functioning and biodiversity of current forest ecosystems. We propose to perform a comparative study on the Eastern Romanian Carpathians, where there are secular forests just classified by UNESCO, and the Northern central Pyrenees, which present the highest density of old-growth forests in Western Europe. To reconstruct their long-term trajectories and characterise the tolerable ones for biodiversity, we propose to combine palaeoecological, ecological, historical and sociological approaches into a multiscalar and systemic research in a retrospective and prospective perspective.

Le projet INVAVISION vise à cartographier finement les fronts d’avancée de la végétation des lisières de forêt et des zones occupées par des plantes invasives à l’aide de technologies spatiales complémentaires. En particulier, il s’agit de mettre au point une méthodologie de changement d’échelle entre les 2 technologies très haute résolution suivantes: le drone de type aile volante eBee générant une cartographie à l’échelle centimétrique/décimétrique et les images satellites Pleiades délivrant une cartographie à l’échelle métrique. Nous souhaitons tester cette nouvelle méthodologie et sa robustesse sur plusieurs sites dans le piémont pyrénéen et la Patagonie chilienne.
