DOWNLOAD EBOOKExtending from west Africa to Madagascar, from the vast lowland Congo Basin to the archipelago of forest islands on its eastern rim, the African rain forest is surpassed in size only by the Amazon. This book sheds light on the current efforts to understand and conserve the African rain forest, an area in need of urgent action to save its biological wealth, cultural heritage, and economic potential. Written by conservation scientists and practitioners based in the African rain forest, the book offers a multidisciplinary perspective that integrates many biological and social sciences. Early chapters trace the forces--from paleoecological factors to recent human actions--that have shaped the African forest environment. The next chapters discuss the dominant biological patterns of species ranging from the distinctive elephants, gorillas, and okapi to the less well known birds, butterflies, and amphibians. Other chapters focus on how such different groups as hunter-gatherers, forest farmers, bushmeat hunters, recent immigrants, and commercial foresters have used the forests. Several authors stress the need for tighter links between research and conservation action. The final section draws lessons from the collective experience of those working in an Africa wracked by political strife and economic hardship.
Regenerating Agriculture

DOWNLOAD EBOOKFor the past 50 years, the main goal of agriculture has been to increase production at any price, using high amounts of fertilizers and pesticides and intensive industrial methods. This has caused damage to the environment and widespread rural depopulation. This study shows that there is a viable alternative - a form of agriculture which conserves resources, maintains rural employment and minimizes the external costs, without loss of productivity. Using case studies from industrialized and developing countries, the author describes the new technical, institutional and policy options available.

DOWNLOAD EBOOKDuring the last ten years the enormous global loss of biodiversity has received remarkable attention. Among the numerous approaches undertaken to stop or lessen this process, access and benefit-sharing (ABS), a market-based approach, has emerged as among the most prominent. In theory, ABS turns biodiversity and genetic resources from an open access good to a private good and creates a market for genetic resources. It internalizes the resources’ positive externalities by pricing the commercial values for research and development and makes users pay for it. Users’ benefits are shared with the resource holders and set incentives for the sustainable use and the conservation of biodiversity. Carmen Richerzhagen, however, finds that in practice there are significant questions about the effectiveness of the approach in the protection of biodiversity and about the fair and equitable sharing of benefits arising from the commercialization. Utilizing the empirical findings of three case studies of biodiversity-providing countries - Costa Rica, the Philippines and Ethiopia - and one case study of a community of user countries, the European Union (EU), Richerzhagen examines the effectiveness of ABS through the realization of its own objectives.

DOWNLOAD EBOOKSouth Africa's fynbos region has intrigued biologists for centuries. It has achieved iconic status as a locus of megadiversity and therefore a place to study the ecological underpinnings of massive evolutionary radiations. Researchers have made great advances over the past two decades in unravelling the complexities of fynbos ecology and evolution, and the region has contributed significant insights into the adaptive radiations of large lineages, conservation science, pollination biology, invasive plant biology, and palaeoanthropology. Lessons from the fynbos offer much of value for understanding the origin, maintenance, and conservation of diversity anywhere in the world. This book provides the first synthesis of the field for 20 years, bringing together the latest ecological and evolutionary research on the South African global biodiversity hotspots of the Greater Cape Floristic Region - the iconic fynbos and succulent karoo. It explores the historical and modern physical and biological environment of this region, the circumstances and processes which have fostered its remarkable biodiversity, and the role this diversity has played in the emergence of modern humans. It also discusses the challenges of contemporary management and conservation of the region's biodiversity in the face of accelerating global change.

DOWNLOAD EBOOKThe field of medicinal/aromatic plant breeding is growing and changing?this resource will help you stay up to date! In this essential book, researchers from large and small laboratories and institutions throughout Europe and the Mediterranean region explore recent developments in the selection and breeding of aromatic and medicinal plants. They take varied approaches?from traditional breeding to the use of molecular markers?and complement them with up-to-date information on biodiversity and resource conservation. From the editors: ?It is widely recognized that a strategy of `conservation through use,? by which plant collection via wild harvesting is replaced by controlled cultivation, is the best way forward if we are to balance human demands with the necessary conservation of the biodiversity represented by these species. That provides one major driving force for research in this field. Another concerns the very real need for improving the quality control of products on the market, both to satisfy consumer demand and to conform with the (justifiably) increasing requirements for standardization and precise identification of the composition of the plant materials being sold for human use. We hope that this volume will give readers a taste of the exciting developments in the field.? Breeding Research on Aromatic and Medicinal Plants examines: breeding for resistance and abiotic factors manipulating natural product accumulation through genetic engineering biochemical and molecular regulation of essential oil accumulation economic and legal considerations that breeders will encounter the ethical aspects of breeding these plants
