This book was released on 2012-04 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: La lecheria en pequena escala, predomina en la zona central de Mexico. Se caracteriza por pequenas unidades que fluctuan entre tres y treinta vacas, mano de obra familiar, aprovechamiento eficientemente de pajas de avena y trigo, rastrojo de maiz, sorgo, pastos y praderas nativas, construcciones rusticas, la leche producida se vende a intermediarios, queseros locales o directamente al consumidor. El ganado es producto de la cruza entre razas Holstein, Pardo Suizo y Criollo. Una alternativa para mejorar el desarrollo de estos sistemas, es la cria de reemplazos en la misma unidad de produccion, con el objetivo de mejorar sus caracteristicas genotipicas y fenotipicas que influyen directamente en su potencial productivo y adaptacion a las condiciones locales. En este tenor, se ha considerado la evaluacion del diametro toracico para predecir el peso del animal en funcion de la edad y, como repercuten las practicas de alimentacion en su desarrollo. Finalmente, proponer alternativas de cria para disminuir los costos de produccion, ya que un gran numero de productores, compran hembras para reemplazo a costos elevados.

This book was released on 2012-04 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico es deficitario en produccion de leche. La lecheria en pequena escala o lecheria campesina, que se desarrolla en el altiplano central, contribuye de forma importante a la oferta nacional de leche. Los hatos no son mayores a 30 vacas, y la disponibilidad de tierra no mayor a 5 ha. El uso de la tierra se divide entre cultivo de maiz y praderas de ballicos bajo pastoreo. Durante el invierno, las estrategias de alimentacion se basan en el uso de concentrados comerciales (de 3 a 6 kg/vaca/dia), y la suplementacion de ensilado de maiz (de 3 a 9 kg de MS/vaca/dia), mas accesos restringidos a pastoreo. Durante la epoca de lluvias, la alimentacion consiste en suplementacion con concentrados (de 3 a 6 kg/vaca/dia), y acceso a pastoreo hasta por 9 h/dia. En este documento se presentan los resultados de la respuesta productiva y economica a la suplementacion de vacas lecheras, con varios niveles de ensilado de maiz en la epoca invernal, y de concentrados en la epoca de lluvias, como una alternativa para reducir costos por concepto de alimentacion en este tipo de sistemas."

Book excerpt: Cultural Materialism, published in 1979, was Marvin Harris's first full-length explication of the theory with which his work has been associated. While Harris has developed and modified some of his ideas over the past two decades, generations of professors have looked to this volume as the essential starting point for explaining the science of culture to students. Now available again after a hiatus, this edition of Cultural Materialism contains the complete text of the original book plus a new introduction by Orna and Allen Johnson that updates his ideas and examines the impact that the book and theory have had on anthropological theorizing.
Download or read book International Code of Conduct on Pesticide Management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-09-03 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Download or read book Beyond the Kale written by Kristin Reynolds and published by University of Georgia Press. This book was released on 2016 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban agriculture is increasingly considered an important part of creating just and sustainable cities. Yet the benefits that many people attribute to urban agriculture-fresh food, green space, educational opportunities-can mask structural inequities, thereby making political transformation harder to achieve. Beyond the Kale argues that urban agricultural projects focused explicitly on dismantling oppressive systems have the greatest potential to achieve substantive social change. Through in-depth interviews and public forums with prominent urban agriculture activists and supporters-primarily people of color and women, whose strategies have often been underrespresented in the literature Kristin Reynolds and Nevin Cohen illustrate how urban farmers and gardeners not only grow food for their communities but also use their activities and spaces to disrupt the dynamics of power and privilege that perpetuate inequity. Beyond the Kale provides recommendations for these in philanthropy, government, nonprofit organizations, and academia to support such initiatives. Book jacket.
Download or read book The State of Food Security and Nutrition in the World 2020 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-07-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.
Download or read book Black White and Green written by Alison Hope Alkon and published by University of Georgia Press. This book was released on 2012-11-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Farmers markets are much more than places to buy produce. According to advocates for sustainable food systems, they are also places to “vote with your fork” for environmental protection, vibrant communities, and strong local economies. Farmers markets have become essential to the movement for food-system reform and are a shining example of a growing green economy where consumers can shop their way to social change. Black, White, and Green brings new energy to this topic by exploring dimensions of race and class as they relate to farmers markets and the green economy. With a focus on two Bay Area markets—one in the primarily white neighborhood of North Berkeley, and the other in largely black West Oakland—Alison Hope Alkon investigates the possibilities for social and environmental change embodied by farmers markets and the green economy. Drawing on ethnographic and historical sources, Alkon describes the meanings that farmers market managers, vendors, and consumers attribute to the buying and selling of local organic food, and the ways that those meanings are raced and classed. She mobilizes this research to understand how the green economy fosters visions of social change that are compatible with economic growth while marginalizing those that are not. Black, White, and Green is one of the first books to carefully theorize the green economy, to examine the racial dynamics of food politics, and to approach issues of food access from an environmental-justice perspective. In a practical sense, Alkon offers an empathetic critique of a newly popular strategy for social change, highlighting both its strengths and limitations.
Download or read book Plants for Arid Lands written by G.E. Wickens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man. Indirect usage includes the needs of Man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. Economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the World today. However, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to Man will be lost for ever. Furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. Fewer than 1 per cent of the World's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the World.
Download or read book Diseases of Sugarcane written by C. Ricaud and published by Elsevier. This book was released on 2012-12-02 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: An extensive volume of Sugarcane Diseases and their World Distribution (Vol. I) was published by Elsevier under the auspices of the International Society of Sugar Cane Technologists in 1961. The present volume was intended to be a new edition of the book, but so many changes were required that a new book was needed. Only three chapters have been kept with slight amendments. The other chapters have been completely re-written. In fact with changes in importance of major diseases, four diseases previously treated have been left out; on the other hand, three new topics have been included in the new book, two new diseases and a chapter on sugarcane quarantine.The first chapter gives a brief account of the anatomy, morphology and physiology of the sugarcane plant to facilitate terminology and especially for a better appreciation of the effect of disease on the growth of the crop. Diseases are extensively treated as in Volume I, with a very good description of their symptoms and variation under different conditions and severity, all well illustrated by black and white figures and in a set of colour plates at the end of the book which will prove of valuable help for identification. The causal agents of the diseases are described giving synonyms, cultural characteristics, isolation methods and present knowledge on race variation, an aspect on which there has been quite an advance in knowledge since Volume I was published. New techniques of diagnosis are also given. Advances in research on the diseases over the last 25 years are well covered and supported by an extensive bibliography at the end of each chapter.The book has been edited by people having first hand experience in the field and in research on these diseases. Authors have been selected from among the most knowledgeable all over the sugar cane world, especially with due regard to the importance of the different diseases in their countries.The book should prove of immense value to those concerned with practical aspects of plant disease control in the field: pathologists, agronomists and crop specialists, including consultants, to those concerned with quarantine of the crop, for university lectures and students, and research scientists.In a pre-publication review D.J. Heinz and S.A. Ferreira of the Hawaiian Sugar Planters' Association stated: ``Much has changed and new information generated since the original version of this book was published in 1961. This new edition incorporates most of it, providing both the laboratory and field sugarcane pathologist a complete and authoritative guide to the major sugarcane diseases of the world. It is the best single book available on sugarcane diseases.''
Download or read book Lake Chilwa written by M. Kalk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leonard C. Beadle In contrast to the more sta bie oceans, inland waters are, on the geological time scale, short-lived and are subject to great fluctuations in chemical composition and physical features. Very few lakes and rivers have existed continuously for more than a million years, and the life of the majority is to be measured in thousands or less. Earth movements, erosion and long-term climatic changes in the past have caused many of them to appear and disappear. No wonder then that most freshwater organism are especially adapted to great changes and many even to temporary extinction of their environment. Recent studies of residual sediments from existing and extinct lakes in tropical Africa have told us much about their age and the past history of their faunas and floras, from which we may deduce something about the climate and the conditions in the water in the past. The forces that have formed and moulded the African Great Lakes have been catastrophic in their violence and effects. They are not yet finished, but the present rate of change is, in human terms, too slow for direct observation of the ecological effects. The large man-made lakes are providing very good opportunities for studying the chemi cal and biological consequences of the initial filling but, once filled, they are artificially protected against major fluctuations.
Download or read book Rise Trading State written by Richard Rosecrance and published by Basic Books. This book was released on 1987-05-31 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: What will power look like in the century to come? Imperial Great Britain may have been the model for the nineteenth century, Richard Rosecrance writes, but Hong Kong will be the model for the twenty-first. We are entering the Age of the Virtual State -- when land and its products are no longer the primary source of power, when managing flows is more important than maintaining stockpiles, when service industries are the greatest source of wealth and expertise and creativity are the greatest natural resources.Rosecrance's brilliant new book combines international relations theory with economics and the business model of the virtual corporation to describe how virtual states arise and operate, and how traditional powers will relate to them. In specific detail, he shows why Japan's kereitsu system, which brought it industrial dominance, is doomed; why Hong Kong and Taiwan will influence China more than vice-versa; and why the European Union will command the most international prestige even though the U.S. may produce more wealth.
