Les perturbations climatiques, l’évolution démographique et les sécheresses des dernières décennies, ont contribué à une rupture d’équilibre entre les systèmes de production pastorale et agricole, au détriment des pasteurs. À côté de ce contexte écosystémique, d’autres facteurs viennent aggraver la situation pastorale dans le Sahel, en particulier le rétrécissement de l’espace pastoral, grignoté par l’expansion des terres agricoles.

Sustainability
Peer-reviewed publicationJanuary, 2019EgyptThe dramatic growth of the world’s population is increasing the pressure on natural resources, particularly on soil systems. At the same time, inappropriate agricultural practices are causing widespread soil degradation. Improved management of soil resources and identification of the potential agricultural capability of soils is therefore needed to prevent further land degradation, particularly in dryland areas such as Egypt. Here, we present a case study in the El-Fayoum depression (Northern Egypt) to model and map soil suitability for 12 typical Mediterranean crops.

Peer-reviewed publicationJanuary, 2022LibyaConversion of native lands into agricultural use, coupled with poor land management practices, generally leads to changes in soil properties. Understanding the undesirable effects of land-use and land-cover (LULC) changes on soil properties is essential when planning for sustainable land management.

Peer-reviewed publicationJanuary, 2023TunisiaSoil erosion is an important environmental problem that can have various negative consequences, such as land degradation, which affects sustainable development and agricultural production, especially in developing countries like Tunisia. Moreover, soil erosion is a major problem around the world because of its effects on soil fertility by nutriment loss and siltation in water bodies. Apart from this, soil erosion by water is the most serious type of land loss in several regions both locally and globally.

Library ResourceJournal Articles & BooksJuly, 2021Northern Africa, Western AfricaCette étude examine l’évolution géographique et temporelle de la violence impliquant les communautés pastorales. Elle s’appuie sur l’analyse de plus de 36 000 évènements violents en Afrique du Nord et de l’Ouest entre janvier 1997 et avril 2020 dans lesquels 206 groupes pastoraux ont été impliqués, pour identifier au niveau régional des schémas plus larges de violence pastorale au cours des deux dernières décennies. Celle-ci s’est intensifiée dans la région, comme en témoigne la forte croissance du nombre d’événements et de victimes cette dernière décennie.

Library ResourceReports & ResearchOctober, 2021Western Sahara, Western Africa
Le foncier est une question à la fois stratégique et centrale dans les processus de développement, et pour cause : la terre avec ses immenses ressources qu’elle englobe, est le premier intrant de la production. A ce titre, elle permet de répondre aux enjeux multiples qui ont pour noms : sécurité alimentaire, emploi agricole surtout pour les jeunes, exportation, etc.
C’est pourquoi la Commission de l’UEMOA s’est très tôt intéressée au foncier dans tous ses aspects, car étant une des questions au cœur du processus d’intégration communautaire.

On a global scale, Sudan perhaps ranks first in terms of pastoralists population size. About
66 per cent of Sudan is arid land, which is mainly pastoralists’ habitat. Pastoralism in the
Sudan involves about 20 per cent of the population and accounts for almost 40 per cent of
livestock wealth [Markakis, 1998: 41]. The livestock sector plays an important role in the
economy of the Sudan, accounting for about 20 percent of the GDP, meeting the domestic
demand for meat and about 70 percent of national milk requirements and contributing about -
