Download or read book Slash and Burn Agriculture written by Cheryl Palm and published by Columbia University Press. This book was released on 2005-08-17 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caused in part by the slash-and-burn practices of both large- and small-scale farmers, the environmental implications of tropical deforestation remain a worldwide concern. Yet the small-scale farmers who use slash-and-burn agriculture depend on it to produce food and make a living for their families. With contributions from scientists, economists, ecologists, and anthropologists, this book provides an overall analysis of the environmental, economic, and social reasons for why slash and burn is so common and presents alternatives to this destructive practice.
Download or read book Peasants Farmers and Scientists written by H.J.W. Mutsaers and published by Springer Science & Business Media. This book was released on 2007-09-04 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the story of tropical agricultural science and agricultural development in the 20th century, focusing on the African farmer and African farming methods. It describes successes as well as fads and failures, many based on the author’s first-hand observations during more than 40 years in tropical agronomy-related fields. Moving into the 21st century, the book explores the rise of computer modeling of crops and crop production.
Download or read book Conserving Africa s Mega Diversity in the Anthropocene written by Joris P. G. M. Cromsigt and published by Cambridge University Press. This book was released on 2017-03-02 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Centring on South Africa's Hluhluwe-iMfolozi Park, this book synthesizes a century of insights from the ecology and conservation management of one of Africa's oldest protected wildlife areas. The park provides important lessons for conservation management, as it has maintained conservation values rivalling those of much larger parks sometimes through, and sometimes despite, strong management interventions, including the rescue of the white rhino from extinction. In addition, the book highlights the ecological science produced in the park, much of which has become widely influential, including the megaherbivore concept, new functional approaches to understanding biomes, and new understandings about the role of consumers in shaping ecosystems. The volume is ideal for researchers and policymakers interested in the conservation of relatively small, isolated and protected areas.
Download or read book Integrated Plant Nutrient Management in Sub Saharan Africa written by and published by CABI. This book was released on 2002 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation and nutrient depletion have become serious threats to agricultural productivity in Africa. Soils cannot supply the quantities of nutrients required and yield levels decline rapidly once cropping commences. This book addresses these issues and includes papers from an international symposium held at Cotonou, Benin, October 9-12, 2000, organized by the International Institute of Tropical Agriculture, Ibadan, Nigeria and the Department of Land Management of the Katholieke Universiteit Leuven, Belgium. In five main parts it marks the end of a first phase of collaborative research on "Balanced Nutrient Management Systems for the Moist Savanna and Humid Forest Zones of Africa" and concludes with recommendations, providing essential reading for crop and soil scientists.
Download or read book Soil and Soil Fertility Management Research in Sub Saharan Africa written by Henk Mutsaers and published by Routledge. This book was released on 2017-03-27 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Judicious soil fertility management is crucial for sustainable crop production and food security in sub-Saharan Africa (SSA). This book describes the various concepts and approaches underlying soil and soil fertility management research in SSA over the last fifty years. It provides examples of important innovations generated and assesses the position of research within the research-to-development continuum, including how innovations have been validated with the intended beneficiaries. Using the experience of the International Institute of Tropical Agriculture (IITA) as a case study, the authors analyse how processes, partnerships and other factors have affected research priorities, the delivery of outputs, and their uptake by farming communities in SSA. They evaluate both successes and failures of past investments in soil fertility research and important lessons learnt which provide crucial information for national and international scientists currently engaged in this research area. The book is organised in a number of chapters each covering a chronological period characterised by its primary research content and approaches and by the dominant research paradigms and delivery models.

Download or read book Voices from the Forest written by Malcolm Cairns and published by Routledge. This book was released on 2010-09-30 with total page 854 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook of locally based agricultural practices brings together the best of science and farmer experimentation, vividly illustrating the enormous diversity of shifting cultivation systems as well as the power of human ingenuity. Environmentalists have tended to disparage shifting cultivation (sometimes called 'swidden cultivation' or 'slash-and-burn agriculture') as unsustainable due to its supposed role in deforestation and land degradation. However, a growing body of evidence indicates that such indigenous practices, as they have evolved over time, can be highly adaptive to land and ecology. In contrast, 'scientific' agricultural solutions imposed from outside can be far more damaging to the environment. Moreover, these external solutions often fail to recognize the extent to which an agricultural system supports a way of life along with a society's food needs. They do not recognize the degree to which the sustainability of a culture is intimately associated with the sustainability and continuity of its agricultural system. Unprecedented in ambition and scope, Voices from the Forest focuses on successful agricultural strategies of upland farmers. More than 100 scholars from 19 countries--including agricultural economists, ecologists, and anthropologists--collaborated in the analysis of different fallow management typologies, working in conjunction with hundreds of indigenous farmers of different cultures and a broad range of climates, crops, and soil conditions. By sharing this knowledge--and combining it with new scientific and technical advances--the authors hope to make indigenous practices and experience more widely accessible and better understood, not only by researchers and development practitioners, but by other communities of farmers around the world.

Download or read book Routledge Handbook of Food and Nutrition Security written by Bill Pritchard and published by Routledge. This book was released on 2016-03-31 with total page 748 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of food and nutrition security has evolved and risen to the top of the international policy agenda over the last decade. Yet it is a complex and multi-faceted issue, requiring a broad and inter-disciplinary perspective for full understanding. This Handbook represents the most comprehensive compilation of our current knowledge of food and nutrition security from a global perspective. It is organized to reflect the wide scope of the contents, its four sections corresponding to the accepted current definitional frameworks prevailing in the work of multilateral agencies and mainstream scholarship. The first section addresses the struggles and progression of ideas and debates about the subject in recent years. The other sections focus on three key themes: how food has been, is and should be made available, including by improvements in agricultural productivity; the ways in which politico-economic and social arenas have shaped access to food; and the effects of food and nutrition systems in addressing human health, known as food utilisation. Overall, the volume synthesizes a vast field of information drawn from agriculture, soil science, climatology, economics, sociology, human and physical geography, the nutrition and health sciences, environmental science and development studies.
