International audience; This study presents a decision support tool that evaluates the environmental efficiency of reusing treated wastewater for agricultural irrigation, among other options. The developed tool is published as open source at https://doi.org/10.18167/DVN...

Description du sujet. Pour la zone écologique du Moyen-Ouest des plateaux d’altitude de Madagascar, six variétés de riz pluvial ont été sélectionnées par un programme de recherche. Objectifs. Il s’agit d’évaluer leur potentiel de diffusion en milieu réel. Méthode. Elles...

Description. La culture du cacaoyer en Guyane tend à se (re)développer et nécessite aujourd’hui des références technico-économiques adaptées. Objectifs. Réalisation d’une évaluation de la viabilité technico-économique de la cacaoculture et de la transformation de ses pr...

Les eaux souterraines sont devenues indispensables pour l’agriculture dans les pays semi-arides et dont les ressources en eau sont sous forte pression. À de rares exceptions près, elles sont longtemps restées invisibles. Leur mise en visibilité – sur les plans physique,...

International audience; In agroforestry systems, fine roots grow at several depths due to the mixture of trees and annual crops. The decomposition of fine roots contributes to soil organic carbon stocks and may impact soil fertility, particularly in poor soils, such as ...

On the outskirts of the city of Bangui, the capital of the Central African Republic, fuelwood production, slash-and-burn agriculture and artisanal timber exploitation are causing deforestation and forest ecosystem degradation. Within the framework of the REDD+ Component...

Today, tree plantations play a crucial role in supplying wood and wood-based products. They supply almost half of global demand, as well as supporting a diversity of ecosystem services. In tropical and subtropical areas, where tree growth is optimum and large tracts of ...

Walnut agroforestry systems require regular tree pruning, generating a large volume of biomass residues which are mainly valorized as wood-energy, Ramial Chipped Wood (RCW) or animal litter. However, walnut is recognized as a rich source of different chemical compounds,...

An inventory of the species in and around the clove agroforestry systems (AFS) on the east coast of Madagascar revealed that none of the currently grown species derive from the native Malagasy biodiversity: the herbaceous and woody plants which comprise planned agrobiod...

Over the past decade, several global maps of above-ground biomass (AGB) have been produced, but they exhibit significant differences that reduce their value for climate and carbon cycle modelling, and also for national estimates of forest carbon stocks and their changes...
