Available in PDF, EPUB and Kindle. Book excerpt: After 42 years of international trade in wild harvested medicinal bark from Africa and Madagascar, the example of Prunus africana holds several lessons for both policy and practice in forestry, conservation and rural development. Due to recent CITES restrictions on P. africana exports from Burundi, Kenya and Madagascar, coupled with the lifting of the 2007 EU ban in 2011, Cameroon’s share of the global P. africana bark trade has risen from an average of 38% between 1995 and 2004, to 72.6% (658.6 (metric tons or t)) in 2012. Cameroon is therefore at the center of this international policy arena. First, despite the need to conserve genetically and chemically diverse P. africana, there are no populations in Cameroon that are completely protected. Commercial harvesting is allowed in Mount Cameroon National Park (MCNP) and enforcement within forest reserves such as Nkom-Wum Forest Reserve, Mount Manengouba is limited. Second, hopes of decentralized governance of this forest product are misplaced due to elite capture, concentration of power and “informal taxation” (bribery). Although shifts away from an export monopoly did occur, this resulted in “resource mining” rather than the intended sustainable resource management after 1987, when 50 Cameroonian entrepreneurs entered the bark trade. In 2004, this halved to 25 companies. In 2007, just nine companies received quotas, only one of which (Afrimed) actually exported bark. Afrimed continues to dominate the export trade to date. As one of four companies under the umbrella of a privately owned Cameroonian bank, Afrimed is different to other exporters in terms of power and influence. At the current European price for P. africana bark (USD 6 per kg), the 2012 bark quota (658.675 t) was worth over USD 3.9 million, most of it accruing to Afrimed. Third, in contrast to lucrative bark exports, livelihood benefits to local harvesters from wild harvests are low. For example, the 48 harvesters working within MCNP receive less than USD 1 per day from bark harvests, due to a net bark price of just USD 0.33 per kg (or 43% of the farm-gate price for wild harvested bark). The costs of maintaining an inventory, monitoring and managing sustainable wild harvests are far greater than the benefits to harvesters. Without the current substantial international donor subsidies, sustainable harvest cannot be sustained. To supply the current and future market, we must develop separate, traceable P. africana bark supply chains based on cultivated stocks. More Cameroonian small-scale farmers cultivate P. africana than farmers in any other country. This change requires CITES and EU support and would catalyze P. africana cultivation in Cameroon, doubling farm-gate prices to harvesters – from the current FCFA 150 per kg (USD 0.33) received by wild bark harvesters to FCFA 294 per kg (USD 0.66 ) – that could be paid to farmers after a 15% traceability cost was deducted.

Download or read book Climate Change and the Management of Natural Systems in Cameroon written by Neba Ndenecho and published by African Books Collective. This book was released on 2011-08-25 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book emphasises that planning is essential, as the conservation approaches of the past may not work in an ever-changing warmer environment. It appraises current management strategies, assesses the biological and physical effects of climate change on natural systems in Cameroon and designs a planning and management framework for each natural system within the context of global warming. Climate change poses a complex bewildering array of problems for ecosystems. The key question is, what can be done in addition to efforts to reduce CO2 emissions to increase the resistance and resilience of these natural systems to climate change? This book seeks to answer the above question by drawing from the vast array of scientific data available on the subject, and which may not be readily available to policy makers, resource planners, resource managers, environmentalists, students of geography, conservation biology and agronomy. It constitutes an important manual for those ready to confront the impacts of climate change. It is also a valuable document for teachers of the functioning and management of natural systems globally.

This book was released on 2019-03-12 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The State of the World's Biodiversity for Food and Agriculture presents the first global assessment of biodiversity for food and agriculture worldwide. Biodiversity for food and agriculture is the diversity of plants, animals and micro-organisms at genetic, species and ecosystem levels, present in and around crop, livestock, forest and aquatic production systems. It is essential to the structure, functions and processes of these systems, to livelihoods and food security, and to the supply of a wide range of ecosystem services. It has been managed or influenced by farmers, livestock keepers, forest dwellers, fish farmers and fisherfolk for hundreds of generations. Prepared through a participatory, country-driven process, the report draws on information from 91 country reports to provide a description of the roles and importance of biodiversity for food and agriculture, the drivers of change affecting it and its current status and trends. It describes the state of efforts to promote the sustainable use and conservation of biodiversity for food and agriculture, including through the development of supporting policies, legal frameworks, institutions and capacities. It concludes with a discussion of needs and challenges in the future management of biodiversity for food and agriculture. The report complements other global assessments prepared under the auspices of the Commission on Genetic Resources for Food and Agriculture, which have focused on the state of genetic resources within particular sectors of food and agriculture.

Available in PDF, EPUB and Kindle. Book excerpt: Insights on current research and recent developments in understanding global savanna systems Increasingly recognized as synonymous with tropical grassy biomes, savannas are found in tropical and sub-tropical climates as well as warm, temperate regions of North America. Savanna Woody Plants and Large Herbivores examines the interactions between woody plants and browsing mammals in global savannas—focusing primarily on the C4 grassy ecosystems with woody components that constitute the majority of global savannas—and discusses contemporary savanna management models and applications. This much-needed addition to current research examines topics including the varying behavior of browsing mammals, the response to browsing by woody species, and the factors that inhibit forage intake. Contributions from an international team of active researchers and experts compare and contrast different savanna ecosystems, offering a global perspective on savanna functioning, the roles of soil and climate in resource availability and organism interaction, and the possible impacts of climate change across global savannas. Fills a gap in literature on savanna management issues, including biodiversity conservation and animal production Applies concepts developed in other biomes to future savanna research Complements contemporary books on savanna or large herbivore ecology Focuses on the woody component of savanna ecosystems and large herbivore interactions in savannas Compares tree-mammal systems of savannas and other eco-systems of temperate and boreal regions Provides numerous case studies of plant-mammal interactions from various savanna ecosystems Savanna Woody Plants and Large Herbivores is a valuable addition to those in fields such as ecology, wildlife and conservation biology, natural resource management, and environmental science.

This book was released on 2014-01-22 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population growth and the drop in the returns from the major cash crop (coffee) for small farmers are the main drivers that have influenced the farming systems and mobility of farmers in the Western Highlands of Cameroon. The main objective of the research that led to this book was to determine the interactions between farming systems and human mobility in this region of Cameroon. A comparative study was conducted through household and field surveys in three villages and conceptualized based on the systems approach. The different types of mobility were influenced by household social factors, the quest for high valued farm plots and hired labour. Urban-rural migration contributed to occupation diversification and social mobility. The sustainability factor was a function of land use intensity, intensity of off-farm inputs, the household adjustment factor and mobility of the household. The sacred groves were rich in plant diversity of varied ecological and economic importance. Nitrogen mining was common at all levels of the farming system. These determinants and types of mobility claims are pertinent to the research area; the sustainability results of the farming systems reflect the reality on the ground; the nutrient flux evaluated at the crop and farm levels constitute a valuable database for future research.
Download or read book Biodiversity and Human Health written by Francesca Grifo and published by Island Press. This book was released on 1997-02-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The implications of biodiversity loss for the global environment have been widely discussed, but only recently has attention been paid to its direct and serious effects on human health. Biodiversity loss affects the spread of human diseases, causes a loss of medical models, diminishes the supplies of raw materials for drug discovery and biotechnology, and threatens food production and water quality. Biodiversity and Human Health brings together leading thinkers on the global environment and biomedicine to explore the human health consequences of the loss of biological diversity. Based on a two-day conference sponsored by the National Institutes of Health, the National Science Foundation, and the Smithsonian Institution, the book opens a dialogue among experts from the fields of public health, biology, epidemiology, botany, ecology, demography, and pharmacology on this vital but often neglected concern. Contributors discuss the uses and significance of biodiversity to the practice of medicine today, and develop strategies for conservation of these critical resources. Topics examined include: the causes and consequences of biodiversity loss emerging infectious diseases and the loss of biodiversity the significance and use of both prescription and herbal biodiversity-derived remedies indigenous and local peoples and their health care systems sustainable use of biodiversity for medicine an agenda for the future In addition to the editors, contributors include Anthony Artuso, Byron Bailey, Jensa Bell, Bhaswati Bhattacharya, Michael Boyd, Mary S. Campbell, Eric Chivian, Paul Cox, Gordon Cragg, Andrew Dobson, Kate Duffy-Mazan, Robert Engelman, Paul Epstein, Alexandra S. Fairfield, John Grupenhoff, Daniel Janzen, Catherine A. Laughin, Katy Moran, Robert McCaleb, Thomas Mays, David Newman, Charles Peters, Walter Reid, and John Vandermeer. The book provides a common framework for physicians and biomedical researchers who wish to learn more about environmental concerns, and for members of the environmental community who desire a greater understanding of biomedical issues.
Download or read book Seasonally Dry Tropical Forests written by Rodolfo Dirzo and published by Island Press. This book was released on 2012-09-26 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject. Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests. The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use. Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.
