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 Voices from the Forest written by Malcolm Cairns and published by Taylor & Francis. This book was released on 2010-09-30 with total page 853 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 Popular Medicinal Plants in Portland and Kingston Jamaica written by Ina Vandebroek and published by Springer Nature. This book was released on 2020-12-05 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the results from over a year of ethnobotanical research in a rural and an urban community in Jamaica, where we interviewed more than 100 people who use medicinal plants for healthcare. The goal of this research was to better understand patterns of medicinal plant knowledge, and to find out which plants are used in consensus by local people for a variety of illnesses. For this book, we selected 25 popular medicinal plant species mentioned during fieldwork. Through individual interviews, we were able to rank plants according to their frequency of mention, and categorized the medicinal uses for each species as “major” (mentioned by more than 20% of people in a community) or “minor” (mentioned by more than 5%, but less than 20% of people). Botanical identification of plant specimens collected in the wild allowed for cross-linking of common and scientific plant names. To supplement field research, we undertook a comprehensive search and review of the ethnobotanical and biomedical literature. Our book summarizes all this information in detail under specific sub-headings.

Download or read book Ecological Succession on Fallowed Shifting Cultivation Fields written by Claudio O. Delang and published by Springer Science & Business Media. This book was released on 2012-12-20 with total page 132 pages. 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.
