Reducing emissions from deforestation and forest degradation (REDD+) requires developing countries to quantify greenhouse gas emissions and removals from forests in a manner that is robust, transparent, and as accurate as possible. Although shifting cultivation is a dominant practice in several developing countries, there is still very limited info...
Article
This study aims to test the relevance of synthetic aperture radar images of medium and high resolution on the characterization of the types of land use in urban areas. To this end, we relied on textural approaches based on second-order statistics. Specifically, we look for texture parameters most relevant for discriminating urban objects. In this r...

L'avènement des images radar de haute résolution, notamment celles de RADARSAT-2, renforce le potentiel de suivi de notre environnement. Cependant l'analyse et l'interprétation des ces images réservent encore bien des défis, tout particulièrement en milieu urbain. Dans ce type de milieu, la complexité des réponses des objets combinée à la variabili...

La texture de surface du sol est l'une des propriétés de base à prendre en considération dans la classification et la cartographie des sols. Une série multitemporelle de quatre images RADARSAT-1 (R-1), deux images RADARSAT-2 (R-2); soit une image pleinement polarimétrique acquise en mode fin avec quadruple polarisation (FQ4) et une en mode standard...
Article
Soil texture is one of the most important soil properties to be considered in soil classification and mapping. A multitemporal series of four RADARSAT-1 (R-1) images, two RADARSAT-2 (R-2) images, one acquired in fine quadpolarization mode (FQ4), and the other in standard dual-polarization mode (HH and HV), an IKONOS image, and a LANDSAT-7 (L-7) ima...
Article
The advent of high-resolution radar images, in particular those of RADARSAT-2, reinforces the potential for the survey of our environment. The analysis and interpretation of those images, however, remains a challenge, particularly regarding the urban environment. In this type of environment, the complexity of responses of the objects combined with...

African communities traditionally use medicinal plants for their primary healthcare. To ensure the sustainable use of these species one of the crucial issues is to document African communities' indigenous medicinal knowledge. To achieve this goal, the present study evaluated the use frequency and the knowledge of local Beninese communities on the e...
