Available in PDF, EPUB and Kindle. Book excerpt: This report is the second in a series of three evaluating underexploited African plant resources that could help broaden and secure Africa's food supply. The volume describes the characteristics of 18 little-known indigenous African vegetables (including tubers and legumes) that have potential as food- and cash-crops but are typically overlooked by scientists and policymakers and in the world at large. The book assesses the potential of each vegetable to help overcome malnutrition, boost food security, foster rural development, and create sustainable landcare in Africa. Each species is described in a separate chapter, based on information gathered from and verified by a pool of experts throughout the world. Volume I describes African grains and Volume III African fruits.

Download or read book New Strategies in Locust Control written by Stephan Krall and published by Springer Science & Business Media. This book was released on 1997-12-01 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.
Download or read book Bears in the Backyard written by Edward R Ricciuti and published by National Geographic Books. This book was released on 2015-09-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A conservation scientist explores the increasing intersection between humans and wild animals Fang and claw have jumped the white picket fence as encounters with cougars in Chicago, alligators in Florida, and bears virtually everywhere have become increasingly commonplace. As cities and suburbs sprawl, and conservation efforts enable wildlife populations to recover, large wild animals are encroaching on human turf. These creatures might be thrilling to see, but they can bite, scratch, and even kill, and attacks on humans will only increase as we come face to face in the man-made landscape. Author Edward R. Ricciuti explores cutting-edge research into why it’s happening, how it impacts all of us, and how to deal with it on both societal and personal levels. Readers will learn how to protect against potential dangers even as they are being thoroughly entertained by hair-raising tales of real-life encounters.
Download or read book The Diet of John the Baptist written by James A. Kelhoffer and published by Mohr Siebeck. This book was released on 2005 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: James A. Kelhoffer offers a comprehensive analysis of Mark 1:6c par. Matt 3:4c in its socio-historical context, the Synoptic gospels and subsequent Christian interpretation. The first chapter surveys various anecdotes about John's food in the Synoptic gospels and notes that there has never been a consensus in scholarship concerning John's locusts and wild honey. Chapters 2 and 3 address locusts as human food and assorted kinds of wild honey in antiquity. Chapter 4 considers the different meanings of this diet for the historical Baptist, Mark, and Matthew. Contemporary anthropological and nutritional data shed new light on John's experience as a locust gatherer and assess whether these foods could have actually sustained him in the wilderness. The last chapter demonstrates that the most prevalent interpretation of the Baptist's diet, from the third through the sixteenth centuries, hails John's simple wilderness provisions as a model for believers to emulate.

Download or read book Locust written by Jeffrey A. Lockwood and published by Basic Books. This book was released on 2009-04-28 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the nineteenth century, swarms of locusts regularly swept across the continent, turning noon into dusk, demolishing farm communities, and bringing trains to a halt as the crushed bodies of insects greased the rails. In 1876, the U.S. Congress declared the locust "the single greatest impediment to the settlement of the country." From the Dakotas to Texas, from California to Iowa, the swarms pushed thousands of settlers to the brink of starvation, prompting the federal government to enlist some of the greatest scientific minds of the day and thereby jumpstarting the fledgling science of entomology. Over the next few decades, the Rocky Mountain locust suddenly -- and mysteriously -- vanished. A century later, Jeffrey Lockwood set out to discover why. Unconvinced by the reigning theories, he searched for new evidence in musty books, crumbling maps, and crevassed glaciers, eventually piecing together the elusive answer: A group of early settlers unwittingly destroyed the locust's sanctuaries just as the insect was experiencing a natural population crash. Drawing on historical accounts and modern science, Locust brings to life the cultural, economic, and political forces at work in America in the late-nineteenth century, even as it solves one of the greatest ecological mysteries of our time.

Download or read book Toxicology in Antiquity written by and published by Academic Press. This book was released on 2018-10-22 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxicology in Antiquity provides an authoritative and fascinating exploration into the use of toxins and poisons in antiquity. It brings together the two previously published shorter volumes on the topic, as well as adding considerable new information. Part of the History of Toxicology and Environmental Health series, it covers key accomplishments, scientists, and events in the broad field of toxicology, including environmental health and chemical safety. This first volume sets the tone for the series and starts at the very beginning, historically speaking, with a look at toxicology in ancient times. The book explains that before scientific research methods were developed, toxicology thrived as a very practical discipline. People living in ancient civilizations readily learned to distinguish safe substances from hazardous ones, how to avoid these hazardous substances, and how to use them to inflict harm on enemies. It also describes scholars who compiled compendia of toxic agents. New chapters in this edition focus chiefly on evidence for the use of toxic agents derived from religious texts. - Provides the historical background for understanding modern toxicology - Illustrates the ways previous civilizations learned to distinguish safe from hazardous substances, how to avoid the hazardous substances and how to use them against enemies - Explores the way famous historical figures used toxins - New chapters focus on evidence of the use of toxins derived from religious texts
Download or read book Living on the Edge written by Le Zwarts and published by BRILL. This book was released on 2016-10-18 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Living on the Edge' examines the function of the Sahel region of Africa as an important wintering area for long-distance migrant birds. It describes the challenges the birds have to cope with – climate change, of course, and rapid man-made habitat changes related to deforestation, irrigation and reclamation of wetlands. How have all these changes affected the birds, and have birds adapted to these changes? Can we explain the changing numbers of breeding birds in Europe by changes in the Sahel, or vice versa? Winner of the BB/BTO Best Bird Book Award 2010 The Jury commented: "It is a tremendous book in every department. It marks a step-change in our knowledge of the ecology of this critically important region in the European-African migration system and of the many species (familiar to us on their breeding grounds) that winter there. The authors combine the latest scientific information with vivid descriptions of landscapes and animals. Their book is richly illustrated with large numbers of drawings, maps and photographs by acclaimed experts. The wealth of coloured graphics has been particularly well thought out and encourages readers to delve into the figures and learn more about the region, rather than having the (all-too-common) opposite effect. Summing up, the jury praises not just the high quality of the texts, the information and the illustrations, but also the sheer pleasure of reading the book: "One of the key attributes of a good book is to be able to grip the reader's attention and transport him or her to another place. We feel confident that [Living on the edge] will have that effect."
