Albizia lebbeck (L.) Benth. and Gliricidia sepium (Jacq.) Kunth ex Walp. are species of the leguminosae group which are promoted in agroforestry. This study aimed at assessing the quality of leafy biomass composts of these two species in order to use them as green manure. For this, composts based on leafy biomasses of Albizia lebbeck and Gliricidia...
Article
A typology of degradation status of phytocenoses was carried out in order to identify the ecological indicators corresponding to each facies of degradation in agro-ecosystems. Phytosociological inventories and tree measurements were carried out in three different status of land degradation. Stratified random sampling, based on a high spatial resolu...

Agro-ecosystem degradation is a real socio-environmental problem in the Sahel. Face to the declining of yields from cultivated soils, populations are adopting various adaptation strategies. This study was conducted to assess the impact of three agricultural technologies on the evolution of soil fertility in the Sahel area of Burkina Faso. Soil was...
Article
Land degradation is a threat to biodiversity and has negative impacts on agricultural communities by aggravating food insecurity. The objective of this study was to examine the responses of native woody species and soil variables to different levels of glacis degradation in the Sahelian zone of Burkina Faso. Field investigations were performed acco...

The adoption of agroforestry at large scale appears to be an efficient solution for the conservation of biodiversity and the well-being of local communities, especially in developing countries. The present study analyzes the factors that influence farmers 'decisions to adopt agroforestry technology promoted by the Ecosystem Based Adaptation (EBA) a...

Le Sahel burkinabé est caractérisé par une forte dégradation des ressources naturelles. Cette régression est imputable à des facteurs naturels et anthropiques. La présente étude concerne les bas-fonds du sous bassin versant du Nakanbé-Dem situé dans la limite australe du Sahel. Dans cette zone dominée par l’agriculture pluviale et l’élevage extensi...

Le secteur semencier est une composante centrale de la sécurité alimentaire. Il est généralement perçu de manière binaire en différentiant les acteurs dits formels (engagés dans la production de semences certifiées) et les acteurs dits informels (engagés dans la production de semences paysannes). Le projet Coex (Gouvernance adaptative pour la Coexi...

Objectif : Ce travail réalisé dans la réserve partielle de faune de Pama et ses périphéries a pour objectif d’évaluer les changements opérés dans la végétation sous l’influence du climat et de l’Homme.Méthodologie et résultats : Des images Landsat de 2001 et 2013 ont été utilisées pour faire la classification de la végétation. Une ordination des si...
Article
La variation spatiale du couvert végétal constitue un des déterminismes majeurs de la qualité des écosystèmes. Elle influence la physionomie spatiale de la végétation ainsi que les mutations des ressources naturelles. L'objectif de ce travail est d'examiner la typologie spatiale de la végétation sahélienne selon le taux de couverture végétale en dé...

Combating climate change and desertification in West Africa RESULTS IN BRIEF Scientists from the EU and West Africa have worked together to investigate the effects of desertification in West Africa and implemented mitigation measures alongside local people. These measures included restoring the ecosystem through tree plantations for carbon sequestration, sometimes known as carbon forestry.© Anne Mette Desertification and land degradation occur in arid, semi-arid and dry sub-humid areas and are driven by climatic variations and human activity. The result can be the degradation of soil and vegetation over billions of hectares of rangeland and cropland. The UNDESERT (Understanding and combating desertification to mitigate its impact on ecosystem services) project was established to provide greater insight into desertification and land degradation, and their impacts on ecosystems. The aim was to combat desertification and land degradation in order to mitigate the impacts on ecosystem services and consequently on human livelihoods. This can set in motion a positive cycle that can contribute to alleviating poverty and generate benefits at the community level in accordance with the United Nation’s Millennium Development Goals. Researchers took an interdisciplinary approach, using remote sensing data with vegetation, soil and socioeconomic information for application in novel computer modelling techniques. They worked with local stakeholders to assess the impact of desertification and to ensure successful implementation of sustainable management practices. In addition, the consortium developed decision-support tools and best practice guidelines for natural resource managers based on early warning indicators of environmental degradation. Risk assessments were conducted in six different case studies on a national and a local scale to investigate the effect of land use and climate change on plant species distribution and diversity patterns. Results showed that both land use and climate pose high risks for plant species distribution and diversity patterns. In addition, climate and land-use changes are a serious risk for the diversity of food species. The consortium employed 17 African PhD students who received training to implement the project's work and help mitigate risks from future demographic and climatic changes. Results will be directly transferred to international programmes in order to support strategies and initiatives. UNDESERT helped to mitigate climate change through increased carbon sequestration. It also provided better scientific understanding of reliable indicators thereby helping policymakers to formulate concrete management interventions for mitigating desertification. In this way the project worked to improve the lives of local people and support capacity building through the close collaboration of scientists and stakeholders.
