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 Invasive Plants Ecological and Agricultural Aspects written by S. Inderjit and published by Springer Science & Business Media. This book was released on 2006-01-16 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive plants have an impact on global biodiversity and ecosystem function, and their management is a complex task. The aim of this book is to discuss fundamental questions of invasion ecology, such as why particular communities become more invasible than others, what the mechanisms of exclusion of native species by invaders are, and whether invasion can be predicted. In addition, agricultural practices influencing invasion, the environmental and economic costs of invasion as well as possible management strategies are discussed. Readers will get a unique perspective on invasion ecology through employing general principles of ecology to plant invasions.
Download or read book Large scale Forest Restoration written by David Lamb and published by Routledge. This book was released on 2014-09-19 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscapes are being degraded and simplified across the globe. This book explores how forest restoration might be carried out to increase landscape heterogeneity, improve ecological functioning and restore ecosystem services in such landscapes. It focuses on large, landscape-scale reforestation because that is the scale at which restoration is needed if many of the problems that have now developed are to be addressed. It also shows how large-scale forest restoration might improve human livelihoods as well as improve conservation outcomes. A number of governments have undertaken national reforestation programs in recent years; some have been more successful than others. The author reviews these to explore what type of reforestation should be used, where this should be carried out and how much should be done. For example, are the traditional industrial forms of reforestation necessarily the best to use in all situations? How can forest restoration be reconciled with the need for food security? And, are there spatial thresholds that must be exceeded to generate economic and environmental benefits? The book also examines the policy and institutional settings needed to encourage large-scale reforestation. This includes a discussion of the place for incentives to encourage landholders to undertake particular types of reforestation and to reforest particular locations. It also considers forms of governance that are likely to lead to an equitable sharing of the costs and benefits of forest restoration.

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 Shifting Cultivation and Environmental Change written by Malcolm F. Cairns and published by Routledge. This book was released on 2015-01-09 with total page 1405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shifting cultivation is one of the oldest forms of subsistence agriculture and is still practised by millions of poor people in the tropics. Typically it involves clearing land (often forest) for the growing of crops for a few years, and then moving on to new sites, leaving the earlier ground fallow to regain its soil fertility. This book 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. Some critics 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, the book shows 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 and local communities. The book focuses on successful agricultural strategies of upland farmers, particularly in south and south-east Asia, and presents over 50 contributions by scholars from around the world and from various disciplines, including agricultural economics, ecology and anthropology. It is a sequel to the much praised "Voices from the Forest: Integrating Indigenous Knowledge into Sustainable Upland Farming" (RFF Press, 2007), but all chapters are completely new and there is a greater emphasis on the contemporary challenges of climate change and biodiversity conservation.

Available in PDF, EPUB and Kindle. Book excerpt: Shifting cultivation is the predominant system of arable farming in the humid and sub-humid tropics, where several hundred million people depend on this system of agriculture for their livelihood. This book documents and systematizes findings in shifting cultivation from over the last six decades, including characterizing secondary succession and relating the changes that fallow vegetation undergoes to the process of soil fertility restoration. This book is essential reading for researchers and students of tropical agriculture and related areas.
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.
