La principale thèse de cet ouvrage est la structure des filières de commercialisation des vivres en Afrique subsaharienne qui, en fait, ne dépend que de deux facteurs, à savoir les caractéristiques de l’aliment en question et le niveau de développement du pays. Dans les pays africains, comme partout dans le monde, un système de commercialisation des produits vivriers comprend un circuit informel et un circuit formel. L’importance de chacun de ces deux circuits diffère généralement selon le niveau de développement économique du pays.

Urbanization is one of the key drivers of change in the world today. The world‟s urban population currently stands at around 3.5 billion. It will almost double to more than 6 billion by 2050. This is a challenge not only for urban areas but also for rural areas, because many people, especially the young, will migrate from rural areas to urban areas over this period. When addressing urbanization challenges, we are also addressing, directly or indirectly, rural and territorial development. What do we have to do to ensure people‟s access to good nutrition in cities?

FAO has been operational in Sierra Leone since 1978. While the country has witnessed signs of development since the end of the decade-long civil war, the recent Ebola epidemic (2014-2016) has complicated this recovery process. FAO is currently focused on restoring livelihoods affected by the Ebola crisis and building human and institutional capacities to make communities more prepared and resilient to disasters.

La publication de ce numéro d’Unasylva coïncide avec deux événements marquants pour les forêts. Les 196 Parties à la Convention-cadre des Nations Unies sur les changements climatiques viennent de se réunir à la Conférence Paris climat 2015 en vue de négocier un accord qui soit en mesure de changer la donne en matière de changement climatique. Toujours à Paris, le Global Landscapes Forum 2015, Forum mondial sur les paysages, a été le théâtre de discussions de haut niveau portant sur la recherche et les politiques qui sous-tendent les questions d’utilisation des terres.

Most issues of Unasylva focus on a specific theme. The objective of this thematic orientation is to examine in depth a given aspect of forest and forestry development in order to highlight its significance and importance within our wider universe. The aim is not to serve as a primer or textbook on the chosen subject (this clearly would he impossible given the limited size of the journal) but rather to present a series of analyses on specific aspects that help to spark interest and awareness.

La situation mondiale de l’alimentation et de l’agriculture 2008 examine les conséquences de la croissance rapide de la production de biocarburants à base de produits agricoles. L’essor des biocarburants liquides a été largement favorisé par les politiques adoptées dans les pays développés, qui ont considéré que cette nouvelle forme d’énergie pouvait atténuer les effets négatifs du changement climatique et contribuer à la sécurité énergétique et au développement de l’agriculture.

In view of the continuing increase in cost and scarcity of mineral fertilizers resulting from the use of high-cost fossil energy, there is renewed interest in organic recycling and biological nitrogen-fixation to improve soil fertility and productivity. The workshop in Alexandria recommended the further promotion of research, development, application and dissemination of information available on various aspects of biological nitrogen-fixation, including symbiotic systems of rhizobia/legume and Azolla/blue-green algae, and free-living nitrogen-fixing bacteria and blue-green algae.
