Nitrate pollution from agriculture is an important environmental problem, caused bythe excessive use of inorganic fertilizers. The internalization of this externality, via a tax onmineral nitrogen, could lead to a second best solution, reducing nitrate emissions. Severalauthors suggest that a…
The Coteaux de Gascogne region, an upland area in south-western France, is a site where studies related to the future of landscapes and the sustainability of natural resource management are well documented. The local agricultural system is induced by a “house centred” society with the…
Soil erosion leads to important environmental problems (e.g. muddy floods, reservoir sedimentation) in cultivated areas of the European loess belt. This study aimed to determine the impact of rainfall seasonality and land use change on soil erosion over the last 40 years in a 94-ha cultivated…

Using a sample of French crop farms during the 1999-2006 period, we test whether lesstechnically efficient farmers are more likely to engage in organic farming in order to benefitfrom conversion subsidies. Despite some limitations in our data, we find no evidence of suchselection effect. On the…
We propose a flexible and adaptable framework to assist the quick design of models dealing with the durability of the extensive livestock systems at the territorial scale. This metamodel results from the collaborative design starting from MAS developed on 7 sites in Latin America, France and…

Global environmental changes observed during recent decades are likely to have had an impact on the distribution of species. Currently, silver fir (Abies alba) is becoming established in the subalpine forests of the west central Alps at elevations higher than 2000 ma.s.l.; prior to the 1970s its…
Once the conditions that led to the creation of the Société Civile des Terres du Larzac (SCTL) have been introduced, the companion modelling approach used with this group of farmers is presented. The agent-based model co-constructed with a group of researchers and technicians is then described,…
This report examines the role of European Union (EU) member States, both collectively and individually, in the current reported wave of foreign land investment in Africa that has led to the current use of the term ‘land grabbing’.It discusses whether this role is consistent with the EU’s…
Dans le cadre de l'initiative de la FAO sur les Directives Volontaires sur la gouvernance responsable de la tenure des terres et des autres ressources naturelles, une réunion de consultation régionale était organisée à Ouagadougou, Burkina Faso les 23-25 juin 2010. La réunion était une…
