The dry forests and woodlands of Sub-Saharan Africa are major ecosystems, with a broad range of strong economic and cultural incentives for keeping them intact. However, few people are aware of their importance, compared to tropical rainforests, despite them being home to more than half of the continent's population. This unique book brings together scientific knowledge on this topic from East, West, and Southern Africa and describes the relationships between forests, woodlands, people and their livelihoods. Dry forest is defined as vegetation dominated by woody plants, primarily trees, the canopy of which covers more than 10 per cent of the ground surface, occurring in climates with a dry season of three months or more. This broad definition - wider than those used by many authors - incorporates vegetation types commonly termed woodland, shrubland, thicket, savanna, wooded grassland, as well as dry forest in its strict sense. The book provides a comparative analysis of management experiences from the different geographic regions, emphasizing the need to balance the utilization of dry forests and woodland products between current and future human needs. Further, the book explores the techniques and strategies that can be deployed to improve the management of African dry forests and woodlands for the benefit of all, but more importantly, the communities that live off these vegetation formations. Thus, the book lays a foundation for improving the management of dry forests and woodlands for the wide range of products and services they provide.

The harvesting, processing and consumption of edible insects is one of the main keys to the sustainability of food chains on the African continent. Insects are the largest and most successful group of animals on the planet and it is estimated that they comprise 80% of all animals. This makes edible insects extremely important to the future survival of large populations across Africa and the world. Insects offer a complete animal protein that includes all 9 essential amino acids and are very competitive with other protein sources. They are also a good source of beneficial unsaturated fats, and many insects have a perfect Omega 3:6 balance. African Edible Insects As Alternative Source of Food, Oil, Protein and Bioactive Components comprehensively outlines the importance of edible insects as food and animal feed and the processing of insects in Africa. The text also highlights indigenous knowledge of edible insects and shows the composition and nutritional value of these insects, plus presents reviews of current research and developments in this rapidly expanding field. All of the main types of edible insects are covered, including their nutritional value, chemical makeup, and harvesting and processing details. The various preparation technologies are covered for each insect, as are their individual sensory qualities and safety aspects. A key aspect of this work is its focus on the role of insects in edible oils and gelatins. Individual chapters focus on entomophagy in Africa and the various key aspects of the continent's growing edible insect consumption market. As it becomes increasingly clear that the consumption of insects will play a major role in the sustainability of food chains in Africa, this work can be used as a comprehensive and up-to-date singular source for researchers looking for a complete overview on this crucial topic.

An updated treatment of management and geomorphology of large rivers around the world The newly revised Second Edition of Large Rivers: Geomorphology and Management delivers a thoroughly updated exploration of the form and function of major rivers. The book brings together a set of papers on the large rivers of the world, offering readers an insightful examination of a demanding subject. The new Second Edition of the book includes fully updated and revised chapters, as well as two entirely new chapters on the Ayeyarwady and the Arctic rivers. This fascinating volume describes the environmental requirements for creating and maintaining a major river system, case studies on over a dozen large rivers from different continents in a variety of physical environments, and the measurement and management of large rivers. Unmatched in scope, Large Rivers sheds light on a subject lacking in comprehensive study. Readers will benefit from the inclusion of: A thorough introduction to the geology of large river systems, hydrology and discharge, transcontinental moving and storage of sediment, and the greatest floods and largest rivers An exploration of the classification, architecture, and evolution of large-river deltas Discussions of sedimentology and stratigraphy of large river deposits, including their recognition in the ancient record and the distinction from incised valley fills An examination of the effects of tectonism, climate change, and sea-level change on the form and behavior of the modern Amazon river and its floodplain Measurement and management of large rivers The effect of climatic change on large rivers Perfect for postgraduate students and researchers in fluvial geomorphology, hydrology, sedimentary geology, and river management, Large Rivers: Geomorphology and Management will also earn a place in the libraries of engineers and environmental consultants in the private and public sectors working on major rivers around the world.

In the Miombo ecoregion (2,865,000 km² or 9.1% of Africa), the Zambezian open forest constitutes the main vegetation unit. It extends to no less than eight countries, from Burundi in the North to South Africa in the South, and from Angola in the West to Mozambique in the East. The austral part of Africa's open forests falls within the Zambezian Regional Center of Endemism outlined by White in 1983. This book focuses mainly on the wetter Zambezian Miombo woodlands. Also patches of mosaic Zambezian dry evergreen forests and small areas of grasslands on Kalahari sands are incorporated in the study. The aim of this book is to gather together the amazing local environment knowledge of Zambezian open forests peoples in order to permit an easier improvement of their well-being. This research has been developed in an ethnoecological way of thinking. Indeed, the synergy arising from putting together local knowledge and updated ecological research provides huge information on ecosystem management, including biodiversity aspects. Ethnoecology is an emergent field that focuses on local peoples' perception and management of complex and co-evolved relationships between the cultural, ecological, and economic components of anthropogenic and natural ecosystems. In the present book, the Zambezian wild edible products are treated according to fourteen items (from fungi, plants and honey, to beverages and salt, through mammals, birds, fish, insects and other animals). Some other comments concern agriculture and ethnoecology. All together more than a thousand edible products are involved; their ecology, their phenology, as well as their nutritional values are presented and discussed. The iconography is supported by a CD with 387 color photographs. The earlier French version of 1997 has been reviewed and enlarged, taking into account recent progress of knowledge. An important bibliography is presented.

Ce livre nous emmène au cœur des zones de forêts denses et sahéliennes de l’Afrique centrale, un écosystème précieux et essentiel à la vie quotidienne de ses habitants, représentant l’un des trois principaux ensembles boisés tropicaux de la planète. Dix pays (Burundi, Cameroun, Congo, Gabon, Guinée Equatoriale, République Centrafricaine, République Démocratique du Congo, Rwanda, Sao Tomé & Principe, Tchad) abritent ces forêts et savanes, riches d’importantes ressources naturelles. Ils ont en commun une longue histoire liée à la colonisation, suivie d'une expérience de coopération multiforme depuis les indépendances qui évolue incontestablement vers une intégration économique et monétaire. De nos jours, alors que les équilibres séculaires entre l’homme et la nature semblent ébranlés, que la sécurité alimentaire, la lutte contre la pauvreté et la préservation de la biodiversité et des ressources forestières sont devenus des enjeux mondiaux ; à l’heure où la croissance démographique non maîtrisée fragilise le maintien des écosystèmes forestiers tout en accentuant les conflits liés à la recherche d’espace vital, le phénomène des changements climatiques vient davantage sonder le génie créateur des populations forestières dans la préservation et la gestion durable de la forêt et des produits forestiers non ligneux (PFNL) qui en sont issus. Cette publication est l’œuvre du personnel technique de la FAO, avec la contribution des partenaires internationaux et locaux engagés dans l’évolution des PFNL. Elle est un document précieux consacré au développement des peuples par la promotion des PFNL en Afrique centrale en vue du renforcement de la sécurité alimentaire et la lutte contre la pauvreté.

Based on work by the Miombo Network in southern Africa, this book helps decision-makers and general readers alike improve their understanding of the socio-ecology of the Miombo woodlands across southern Africa. It also highlights the importance of and the need for further research on the unique Miombo ecology and its link with economic development. One major challenge facing these woodlands is the influence that direct (both natural and anthropogenic) and indirect drivers of change, as well as interactions between these, have had over the centuries. As such the book explores the socio-economic and ecological interactions that occur in these woodlands and discusses the need for further research to provide a better understanding of these interactions. Drawing on data and information from numerous studies conducted in the last 20 years, the book presents a comparative analysis of policy changes and management experiences in the countries concerned. It also addresses issues of global climate change, since they have an impact on Miombo ecosystem management and restoration, and provides future projections based on an assessment of how climate change has affected the Miombo woodlands in the past.
