Tropical forage crops used to feed the livestock are of crucial important in the sustainable development of hot regions. The first part of this work is intended to guide the choice of forage plants and their crops (diversity of forage plants and their uses based on environments and livestock systems). The second focuses on the growing and management of forage crops (production techniques from planting to harvesting the crops). The challenges of woody forage, production of forage seed and the economics of forage production are also addressed. A CD-ROM presents case studies, illustrations and sheets for each plant.

Les terres consacrées à l'élevage couvrent près de 4 millions d'hectares dans le monde, soit 80 % des surfaces agricoles et la demande en produits animaux est en hausse constante, notamment dans les pays tropicaux. D'une importance capitale dans le développement durable des régions chaudes, la production fourragère est le principal levier de la productivité des systèmes d'élevage. Elle joue également un rôle essentiel pour les systèmes qui allient productions végétales et animales et de nombreux systèmes agroécologiques intègrent des plantes fourragères. La première partie de cet ouvrage est destinée à guider le choix de plantes fourragères et de leurs cultures (diversités des plantes, des usages, des milieux et des types d'élevage). La seconde partie est consacrée aux techniques de culture, à la gestion des fourrages, à la valorisation des ligneux, à la production de semences et à l'économie de ces productions. L'ouvrage est accompagné d'un cédérom qui comprend des études de cas originales, des textes et des photos complémentaires, une bibliographie. Cet ouvrage de synthèse s'adresse aux éleveurs, agronomes, techniciens, professionnels des productions animales et fourragères.

Crimes against Nature reveals the hidden history behind three of the nation's first parklands: the Adirondacks, Yellowstone, and the Grand Canyon. Focusing on conservation's impact on local inhabitants, Karl Jacoby traces the effect of criminalizing such traditional practices as hunting, fishing, foraging, and timber cutting in the newly created parks. Jacoby reassesses the nature of these "crimes" and provides a rich portrait of rural people and their relationship with the natural world in the late nineteenth and early twentieth centuries.
