Book Synopsis Ecological Succession on Fallowed Shifting Cultivation Fields by : Claudio O. Delang

Download or read book Ecological Succession on Fallowed Shifting Cultivation Fields written by Claudio O. Delang. This book was released on 2012-12-20. Available in PDF, EPUB and Kindle. Book excerpt: The book reviews the literature on the ecological succession of plants on fallowed swiddens in tropical forests. Patterns of ecological succession in tropical forests are insufficiently understood, partly because results are scattered through a large number of case studies reported in academic articles. So far, no publication has attempted to bring these different case studies together to identify common patters and trends. The goal of the book is to review the different case studies, and identify common patterns of ecological succession in fallowed swiddens, as well as to pinpoint the factors that cause ecological succession in some areas to differ from those in other areas. The book is organised in four different sections: forest structure, forest diversity, species composition, and the factors that contribute to differences in forest recovery rates (the number of times the field was burned, the length of fallow period, the type of soil, and the type of forest). This book is an important contribution to tropical forestry and shifting cultivation. Deforestation and forest degradation are the largest sources of CO2, and shifting cultivation is one of the main culprits. For this (and other economic and political) reason governments attempt to curtail shifting cultivation by shortening the years the fields can be left fallow, or outright outlawing the farming practice. Yet, there is insufficient understanding of the processes of ecological succession in fallows, which raises the questions as to whether the policy fulfils its objectives. ​

Book Synopsis Shifting Cultivation and Secondary Succession in the Tropics by : Albert O. Aweto

Download or read book Shifting Cultivation and Secondary Succession in the Tropics written by Albert O. Aweto. This book was released on 2013-01-01. 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.

Book Synopsis Human Ecology by : Gerald G Marten

Download or read book Human Ecology written by Gerald G Marten. This book was released on 2010-09-23. Available in PDF, EPUB and Kindle. Book excerpt: 'The scope and clarity of this book make it accessible and informative to a wide readership. Its messages should be an essential component of the education for all students from secondary school to university... [It] provides a clear and comprehensible account of concepts that can be applied in our individual and collective lives to pursue the promising and secure future to which we all aspire' From the Foreword by Maurice Strong, Chairman of the Earth Council and former Secretary General of the United Nations Conference on Environment and Development (Earth Summit) The most important questions of the future will turn on the relationship between human societies and the natural ecosystems on which we all, in the end, depend. The interactions and interdependencies of the social and natural worlds are the focus of growing attention from a wide range of environmental, social and life sciences. Understanding them is critical to achieving the balance involved in sustainable development. Human Ecology: Basic Concepts for Sustainable Development presents an extremely clear and accessible account of this complex range of issues and of the concepts and tools required to understand and tackle them. Extensively supported by graphics and detailed examples, this book makes an excellent introduction for students at all levels, and for general readers wanting to know why and how to respond to the dilemmas we face.

Book Synopsis Shifting Cultivation Policies by : Malcolm Cairns

Download or read book Shifting Cultivation Policies written by Malcolm Cairns. This book was released on 2017-11-13. Available in PDF, EPUB and Kindle. Book excerpt: Shifting cultivation supports around 200 million people in the Asia-Pacific region alone. It is often regarded as a primitive and inefficient form of agriculture that destroys forests, causes soil erosion and robs lowland areas of water. These misconceptions and their policy implications need to be challenged. Swidden farming could support carbon sequestration and conservation of land, biodiversity and cultural heritage. This comprehensive analysis of past and present policy highlights successes and failures and emphasizes the importance of getting it right for the future. This book is enhanced with supplementary resources. The addendum chapters can be found at: www.cabi.org/openresources/91797

Book Synopsis The Agricultural Dilemma by : Glenn Davis Stone

Download or read book The Agricultural Dilemma written by Glenn Davis Stone. This book was released on 2022-06-30. Available in PDF, EPUB and Kindle. Book excerpt: The Agricultural Dilemma questions everything we think we know about the current state of agriculture and how to, or perhaps more importantly how not to, feed a world with a growing population. This book is about the three fundamental forms of agriculture: Malthusian (expansion), industrialization (external-input-dependent), and intensification (labor-based). The best way to understand the three agricultures, and how we tend to get it wrong, is to consider what drives their growth. The book provides a thoughtful, critical analysis that upends entrenched misconceptions such as that we are running out of land for food production and that our only hope is the development of new agricultural technologies. The book contains engaging and enlightening vignettes and short histories, with case studies drawn from across the globe to bring to life this important debate and dilemma. The book concludes by arguing there is a viable alternative to industrial agriculture which will allow us to meet the world's needs and it ponders why such alternatives have been downplayed, obscured, or hidden from view. This important book is essential reading for all studying and researching food production and agriculture, and more broadly for all interested in ensuring we are able to feed our growing population.
