The soil organic carbon plays an important role in climate change regulation through carbon emissions and sequestration due to land use changes, notably tropical deforestation. Monitoring soil carbon emissions from shifting-cultivation requires to evaluate the amount of carbon stored at plot scale with a sufficient level of accuracy to be able to d...
Thesis
Full-text available
En Côte d’Ivoire, pour appuyer les politiques de réduction de la déforestation et mieux comprendre les dynamiques en cours, des cartographies fines et régulières des changements d’occupation et d’usage des terres sont nécessaires. Cependant, ces études sont rarement conduites sur de grands territoires ou elles sont parfois obsolètes à cause de la r...
Article
Full-text available
The fight against deforestation and forest degradation is now a major challenge for the preservation of global forest ecosystems. The remote sensing forest monitoring methods that are currently deployed are not always adapted to the Ivorian context because of the high cloud cover, diversity of shaded crops, and land clearing techniques. This study...

Madagascar is recognized both for its unparalleled biodiversity and the high level of threat suffered by this biodiversity, associated in particular with anthropogenic deforestation. Despite sustained efforts to fight poverty and curb deforestation, forest cover in Madagascar is rapidly decreasing. To try to explain why it is so difficult to stop d...
Article
Remote sensing observations such as NDVI trends can provide important insights into past and present states of land condition. However, they do not directly provide comprehensive information about our representation of land degradation and the processes at work. This study aimed to analyze vegetation productivity underlying factors in order to asse...
Article
Full-text available
Sequestration of soil organic carbon (SOC) in agricultural systems is a key indicator of soil fertility improvement and climate change mitigation at the global scale. In Madagascar, the effect of management conversion from traditional practices to agroecological ones on SOC sequestration remains unclear. The objectives of this study therefore were...
Article
Full-text available
Land degradation and regeneration are complex processes that greatly impact climate regulation, ecosystem service provision and population wellbeing and require an urgent and appropriate response through land use planning and interventions. Spatially explicit land change models can greatly help decision makers, but traditional regression approaches...
Presentation
Full-text available
Miombo woodland is the most extensive tropical dry forest formation in Africa, considered as a major biodiversity hotspot but is facing important threats including deforestation due to subsistence agriculture. To mitigate these impacts, passive or assisted forest regeneration is a key solution but little is known on the dynamics of this particular...
Article
Full-text available
The island of Madagascar has a unique biodiversity, mainly located in the tropical forests of the island. This biodiversity is highly threatened by anthropogenic deforestation. Existing historical forest maps at national level are scattered and have substantial gaps which prevent an exhaustive assessment of long-term deforestation trends in Madagas...

Article
Soil organic carbon (SOC) plays an important role in climate change regulation notably through release of CO2 following land use change such a deforestation, but data on stock change levels are lacking. This study aims to empirically assess SOC stocks change between 1991 and 2011 at the landscape scale using easy-to-access spatially-explicit enviro...
Article
Assessment of soil organic carbon stocks (SOCs) is highly relevant considering that SOCs is the central driver in climate change mitigation and soil fertility. In Madagascar, a first attempt at mapping SOCs on a national scale was undertaken in 2009 with previous soil data. Advanced research on soil carbon mapping on a global scale is required to e...
