The population of Sudan reached 30.9 million people in the last population census (2008), and is
projected to reach 39.7 people by 2016, growing at a 2.8% growth rate per annum. With this rate
of increase the population could double up in in about 16 years.
The urban population constituted about 29.8% of the total 2008 population, which indicates that
Sudan is predominantly rural. This high rate of population increase, and the tendency towards
population concentration in large urban centers, constitutes one of the biggest challenges facing

Publication évaluée par des pairsdécembre, 2016Burkina Faso, République centrafricaine, Cameroun, Algérie, Érythrée, Éthiopie, Mali, Mauritanie, Niger, Nigéria, Soudan, Sénégal, Soudan du Sud, TchadAfter the severe droughts in the 1970s and 1980s, and subsequent debates about desertification, analyses of satellite images reveal that the West African Sahel has become greener again. In this paper we report a study on changes in tree cover and tree species composition in three village landscapes in northern Burkina Faso, based on a combination of methods: tree density change detection using aerial photos and satellite images, a tree species inventory including size class distribution analysis, and interviews with local farmers about woody vegetation changes.

This study examines the socioeconomic features that underpin the expansion of groundwater-dependent irrigation in Northern State, Sudan. Groundwater development in the region serves as an economic lifeline given the poor Nile-based irrigation infrastructure and future changes in Nile hydrology. Groundwater-dependent irrigation is found to be expanding in previously uncultivated regions increasingly distant from the Nile.

Includes land regulatory framework; foreign direct investment and large-scale land acquisition; mechanized farming agriculture; lack of transparency and corruption in land use and allocation; land and conflict. Argues that land tenure insecurity has resulted from the imposition of formal law that does not recognize individual rights to unregistered land. State authorities have considered unregistered land to be state land and thus available to transfer to private commercial interests, the military, land speculators, and elites without regard for customary rights.

Evaluation of existing and potential feed resources was conducted in Orodora district in the Southern region of Burkina Faso using Feed Assessment Tool (FEAST). The assessment was carried out through focus group discussions and individual interviews in Mahon and Sayaga communities in Orodara district. The study sites were characterized by mixed crop-livestock production systems. Seventy-percent of cropping activities were focused on fruit tree cultivation while food crop production accounted for the rest.

Les études sur la transhumance ont souvent ciblé les pasteurs – notamment peuls – des zones sahéliennes. Pour en donner une autre perspective, la présente étude a été centrée sur les pratiques de la transhumance dans la zone soudano-sahélienne du Mali en intégrant la perception des agriculteurs et des pasteurs sédentaires concernés par la transhumance dans les zones d’accueil. Les scénarios envisageables pour le futur des systèmes pastoraux ont aussi été analysés. Les données ont été collectées à travers des groupes de discussion et des enquêtes individuelles.
