This book was released on 2019-11-06 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: De la préhistoire au XXe siècle, l'Afrique révèle par son histoire agricole combien diversifié est son patrimoine. La formation d'un « Sahara vert » a sans doute favorisé son peuplement et les premières domestications de végétaux et d'animaux du néolithique africain. Puis l'assèchement progressif du Sahara a imposé la migration vers le Sud, en même temps que de nombreuses espèces végétales et animales, et les techniques agricoles, s'introduisaient. Certaines agricultures « traditionnelles » toujours pratiquées en portent l'empreinte. Ce volume 3 (Tome 5) porte essentiellement sur l'agriculture et la recherche agricole de l'entre-deux-guerres mondiales.

This book was released on 2005 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'histoire de la recherche agricole en Afrique tropicale francophone d�crit l'itin�raire que le patrimoine technologique de l'agriculture en Afrique a parcouru � travers des mill�naires, pour se constituer. Elle montre le cheminement de la cr�ation technologique, " obscur et silencieux ", au d�part, vers une recherche organis�e et scientifique, qui s' est mise en place d�s la fin du 19�me si�cle avec une finalit� immuable : la satisfaction des besoins alimentaires, �conomiques, sociaux et culturels des �tres humains. Ce document constitue une r�f�rence pour tous, hommes politiques, citoyens, agronomes, scientifiques et bailleurs de fonds, et pourrait �tre leur point de ralliement pour le devenir d'un continent africain d�barrass� d�finitivement de la faim, de l'ins�curit� alimentaire et de la pauvret� au cours du 21�me si�cle.

Available in PDF, EPUB and Kindle. Book excerpt: "Agricultural Research and Innovation in Tropical Africa is an in-depth review of the role of research in the development of West and Central African agriculture. In contrast to the conventional wisdom, this vast region has been the site of successive agricultural growth dynamics, in which research has played a key role. Yet outside of the agro-industrial sector, the adoption of complete "technical packages" has been rare. Innovation in smallholder agriculture has, instead, been partial and selective, following patterns unanticipated by the research system, that reflect constraints operating at the farm level: labor scarcity, limited access to capital, and a combination of agricultural and economic risk. Although a favorable economic environment has been essential for growth and innovation, there is no magic formula concerning the types of institutions most suited to the task. For output markets, the issues seems less one of public versus private, than of reliability. Upstream, both input supply and the availability of improved planting material appear to depend either on outright public support, or else on a vertically integrated crop sector. Agriculture in this region cannot hope to respond to the challenges lying ahead without major efforts by national and international research. Foremost among the challenges is competitiveness in world and local markets, against a background in which both sustainability of production systems and constraints at the farm level are better integrated into research strategies."--Page 15
