Download or read book Statistical Design and Analysis for Intercropping Experiments written by Walter T. Federer and published by Springer Science & Business Media. This book was released on 2008-01-08 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intercropping is an area of research for which there is a desperate need, both in developing countries where people are rapidly depleting scarce resources and still starving, and in developed countries, where more ecologically and economically sound ways of feeding ourselves must be developed. The only published guidelines for conducting such research and analyzing the data have been scattered about in various journal articles, many of which are hard to find. This book condenses these methods and will be immensely valuable to agricultural researchers and to the statisticians who help them design their experiments and interpret their results.

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 1057 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.
Download or read book Guidelines for brackish water use for agricultural production in the Near East and North Africa region written by Food and Agriculture Organization of the United Nations and published by Food and Agriculture Organization of the United Nations. This book was released on 2023-01-26 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water scarcity is one of the major challenges in the 19 countries of the Near East and North Africa (NENA) region. The lack of water is affecting important irrigated areas, limiting the increase of food production needed to address the growing demand due to population growth. In most countries of the NENA region, the need to use non-conventional water resources, including brackish water, is well recognized. Brackish water is loosely defined as water that is more saline than freshwater, but less saline than seawater. It covers a large range of salinity levels, from 500 to 30 000 mg/l of total dissolved solids (TDS). Despite the presence of large amounts of brackish water and its potential for use in growing a number of crops, it is only used in limited amounts for irrigation. The successful use of brackish water for irrigation requires a basic understanding of scientific principles affecting the interactions among the climate, the applied water, the soil, the crop, and the environment. Equally important is the application of suitable technology and management practices that will facilitate the optional use of this poor-quality water. The successful use of brackish water requires a higher level of management and likely the adoption of new irrigation management practices. Because climate, water quality, soil type, and crop tolerance to salinity vary from location to location, guidelines, with some degree of site-specific flexibility, must be developed.
Download or read book Pesticide residues in food 2019 Evaluations 2019 Part I Residues written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-12-05 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2019 Extra Joint FAO/WHO Meeting on Pesticide Residues (JMPR) was held in Gatineau/Ottawa, Canada from 7 to 17 May. The FAO and WHO Joint Meeting on Pesticide Residues (JMPR) is an expert ad hoc body administered jointly by FAO and WHO in the purpose of harmonizing the requirement and the risk assessment on the pesticide residues. The JMPR meets annually to evaluate possible hazards to humans arising from the occurrence of pesticide residues in foods. The Evaluation monographs of pesticide residues in food 2019-Part I (e-version only) includes summary of the residue data considered by the 2019 JMPR. The JMPR is the only scientific advisory body to service the Codex and FAO member countries in risk assessment of pesticide residues and in establishment of Codex MRL in food and feed. The JMPR report and evaluations are the unique technical publications in the review of pesticide residue data from around the world. The Report provides the evaluations of the Joint Meeting of the FAO Panel of Experts on Pesticide Residues in Food and the Environment and the WHO Core Assessment Group on Pesticide Residues. The extra Meeting evaluated 19 pesticides, including eight new compounds and three compounds that were re-evaluated for toxicity or residues, or both, within the periodic review programme of the Codex Committee on Pesticide Residues (CCPR).

Book excerpt: An icon of the environmental movement outlines a provocative approach for reclaiming our planet According to Stewart Brand, a lifelong environmentalist who sees everything in terms of solvable design problems, three profound transformations are under way on Earth right now. Climate change is real and is pushing us toward managing the planet as a whole. Urbanization?half the world?s population now lives in cities, and eighty percent will by midcentury?is altering humanity?s land impact and wealth. And biotechnology is becoming the world?s dominant engineering tool. In light of these changes, Brand suggests that environmentalists are going to have to reverse some longheld opinions and embrace tools that they have traditionally distrusted. Only a radical rethinking of traditional green pieties will allow us to forestall the cataclysmic deterioration of the earth?s resources. Whole Earth Discipline shatters a number of myths and presents counterintuitive observations on why cities are actually greener than countryside, how nuclear power is the future of energy, and why genetic engineering is the key to crop and land management. With a combination of scientific rigor and passionate advocacy, Brand shows us exactly where the sources of our dilemmas lie and offers a bold and inventive set of policies and solutions for creating a more sustainable society. In the end, says Brand, the environmental movement must become newly responsive to fast-moving science and take up the tools and discipline of engineering. We have to learn how to manage the planet?s global-scale natural infrastructure with as light a touch as possible and as much intervention as necessary.

Download or read book The Kung San written by Richard Borshay Lee and published by Cambridge University Press. This book was released on 1979-12-12 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: For most of human history hunting and gathering was a universal way of life. Richard Borshay Lee spent over three years conducting fieldwork among the !Kung San, an isolated population of 1,000 in northern Botswana. When Lee began his work in 19863, the !Kung San were one of the last of the world's people to live this life. By 1973, when Lee last lived with the group, it appeared that they !Kung were a society on the threshold of a transformation that signalled the end of foraging as an independent way of life, at least in Africa. The !Kung San: Men, Women and Work in a Foraging Society, an ecological and historical study, is Professor Lee's major statement on his research. By maintaining simultaneous historical and synchronic perspectives, Lee is able to extend his analysis of core features from the contemporary !Kung to prehistoric societies. These basic principles become the means to understanding the form of human life that has been obscured by the developments and complications of societies during the last few thousand years.

Download or read book Sustainable Tourism Dialogues in Africa written by Judy Kepher Gona and published by Walter de Gruyter GmbH & Co KG. This book was released on 2022-03-21 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on the future of tourism, Sustainable Tourism Dialogues in Africa is inclusive of experienced and emerging researchers, as well as incorporating local stakeholders in the tourism industry: architects, tourism operators, sustainable tourism lobbyists, policy makers, archaeologists, and geographers. The editors are frontline sustainable tourism advocates in Africa, and the book’s thematic content is derived from 30 inter-university seminars on sustainable tourism hosted by Sustainable Travel & Tourism Agenda Kenya from 2017 to November 2019. These seminars involved the participation of 17 universities in Kenya, tourism operators, conservationists, developmentalists, investors, policy makers, and students. Every chapter is a voice projecting aspirations for the responsible management of tourism in Africa and promoting the ideals of sustainable tourism that young people in Africa advocate for the industry’s future. In so doing, the authors pinpoint the necessary actions for bringing about transformations in sustainable development of tourism. The book thus seeks to encourage debate, while facilitating the development of both theoretical and practical foundations for managing tourism sustainably in Africa.
