Download or read book Crop Evolution Adaptation and Yield written by L. T. Evans and published by Cambridge University Press. This book was released on 1996-05-02 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this major 1993 work, Lloyd Evans provides an integrated view of the domestication, adaptation and improvement of crop plants, bringing together genetic diversity, plant breeding, physiology and aspects of agronomy. Considerations of yield and maximum yield provide continuity throughout the book. Food, feed, fibre, fuel and pharmaceutical crops are all discussed. Cereals, grain legumes and root crops, both temperate and tropical, provide many of the examples, but pasture plants, oilseeds, leafy crops, fruit trees and others are also considered. After the introductory chapter, the increasing significance of crop yields to the world's food supply is highlighted. The next three chapters consider changes to crop plants over the last ten thousand years, including domestication, adaptation and improvement. Aimed at research workers and advanced students in crop physiology and ecology, agronomy and plant breeding, this book also reaches conclusions of relevance to those concerned with developmental policy, agricultural research and management, environmental quality, resource depletion and human history.

Available in PDF, EPUB and Kindle. Book excerpt: Food historian Cynthia Clampitt pens the epic story of what happened when Mesoamerican farmers bred a nondescript grass into a staff of life so prolific, so protean, that it represents nothing less than one of humankind's greatest achievements. Blending history with expert reportage, she traces the disparate threads that have woven corn into the fabric of our diet, politics, economy, science, and cuisine. At the same time she explores its future as a source of energy and the foundation of seemingly limitless green technologies. The result is a bourbon-to-biofuels portrait of the astonishing plant that sustains the world.

Download or read book Crop Ecology written by David J. Connor and published by Cambridge University Press. This book was released on 2011-04-28 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food security and environmental conservation are two of the greatest challenges facing the world today. It is predicted that food production must increase by at least 70% before 2050 to support continued population growth, though the size of the world's agricultural area will remain essentially unchanged. This updated and thoroughly revised second edition provides in-depth coverage of the impact of environmental conditions and management on crops, resource requirements for productivity and effects on soil resources. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology and morphology. System concepts are explored in detail throughout the book, giving emphasis to quantitative approaches, management strategies and tactics employed by farmers, and associated environmental issues. Drawing on key examples and highlighting the role of science, technology and economic conditions in determining management strategies, this book is suitable for agriculturalists, ecologists and environmental scientists.

Book excerpt: From a Harvard scholar and former Obama official, a powerful proposal for curtailing violent crime in America Urban violence is one of the most divisive and allegedly intractable issues of our time. But as Harvard scholar Thomas Abt shows in Bleeding Out, we actually possess all the tools necessary to stem violence in our cities. Coupling the latest social science with firsthand experience as a crime-fighter, Abt proposes a relentless focus on violence itself -- not drugs, gangs, or guns. Because violence is "sticky," clustering among small groups of people and places, it can be predicted and prevented using a series of smart-on-crime strategies that do not require new laws or big budgets. Bringing these strategies together, Abt offers a concrete, cost-effective plan to reduce homicides by over 50 percent in eight years, saving more than 12,000 lives nationally. Violence acts as a linchpin for urban poverty, so curbing such crime can unlock the untapped potential of our cities' most disadvantaged communities and help us to bridge the nation's larger economic and social divides. Urgent yet hopeful, Bleeding Out offers practical solutions to the national emergency of urban violence -- and challenges readers to demand action.

Download or read book Conservation Agriculture written by L. García-Torres and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.
