Aujourd’hui, la périurbanisation est reconnue comme un phénomène mondial animée par différents déterminants (poussée démographique, développement industriel, crise de la ruralité, etc.).
‘Over the past three decades hundreds of thousands of farmers in Burkina Faso and Niger, on the fringes of the Sahara Desert, have transformed large swathes of the region’s arid landscape into productive agricultural land, improving food security for about three million people. Once-denuded landscapes are now home to abundant trees, crops, and livestock.'
Drylands occupy more than 40% of the world’s land area and are home to some two billion people. This includes a disproportionate number of the world’s poorest people, who live in degraded and severely degraded landscapes.
The importance of studying coastal areas is justified by their resources, ecosystem services, and key role played in socio-economic development. Coastal landscapes are subject to increasing demands and pressures, requiring in-depth analyses for finding appropriate tools or policies for a sustainable landscape management.
The Re-Greening of the West African Sahel has attracted great interdisciplinary interest since it was originally detected in the mid-2000s. Studies have investigated vegetation patterns at regional scales using a time series of coarse resolution remote sensing analyses. Fewer have attempted to explain the processes behind these patterns at local scales.
Desertification is defined as land degradation occurring in the global drylands. It is one of the global problems targeted under the Sustainable Development Goals (SDG 15). The aim of this article is to review the history of desertification and to evaluate the scientific evidence for desertification spread and severity.
The support plan for the Sahel is a regional approach to collectively address the root causes of disruptions such as poverty, migration and youth unemployment, climate change, insecurity, governance and institutional issues in the region.
Le mercredi 20 mars 2019 dans les locaux de l’AFD à Paris, le Comité technique « Foncier & développement » a organisé une réunion consacrée aux politiques foncières et de mise en valeur des terres en Algérie.
This is a presentation on the functionally context socio-ecological type (fCSET) approach to support out-scaling of agricultural innovation options, and empirical analysis across three Maghreb countries (Tunisia, Algeria and Morocco). As the result, distinguished fCSETs on rain-fed and grass/herbaceous-based land were defined, characterized and mapped.
