This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Download or read book Beekeeping for Poverty Alleviation and Livelihood Security written by Rakesh Kumar Gupta and published by Springer. This book was released on 2016-09-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Book intends to address all aspects needed to develop beekeeping into a powerful instrument of rural development and will focus on beekeeping as a tool for Poverty Alleviation and Livelihood security. In the backdrop of the social and economic issues of the people living in poverty region, the book aims to delineate specific motivation approaches to engage them in beekeeping and will serve as a guide for effective marketing through diversification and value addition of bee products. Nevertheless, marketing and environmental issues will remain an important component of this book. The aim is also to focus on indirect benefit of beekeeping so that it is integrated with farming and nature conservation. Other topics include ensuring the provision of practical techniques in handling and management of bees. It will provide detailed information on good contacts with policymakers and authorities; and channels for attracting finance especially in the third world countries. An interdisciplinary approach is the key feature of the book and it will also focus on few case histories and success stories to encourage the reader to take up beekeeping as a new venture gradually in a phased manner like traditional-transitional and modernised beekeeping. With the publication of this book, we hope to hand out a practical guide that will assist all those who are involved in beekeeping for development. We hope it will stimulate beekeeping as an integrated activity with farming and nature conservation and will serve in many households for poverty alleviation and livelihood security.

Download or read book The Biology of the Honey Bee written by Mark L. Winston and published by Harvard University Press. This book was released on 1991-04-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: From ancient cave paintings of honey bee nests to modern science’s richly diversified investigation of honey bee biology and its applications, the human imagination has long been captivated by the mysterious and highly sophisticated behavior of this paragon among insect societies. In the first broad treatment of honey bee biology to appear in decades, Mark Winston provides rare access to the world of this extraordinary insect. In a bright and engaging style, Winston probes the dynamics of the honey bee’s social organization. He recreates for us the complex infrastructure of the nest, describes the highly specialized behavior of workers, queens, and drones, and examines in detail the remarkable ability of the honey bee colony to regulate its functions according to events within and outside the nest. Winston integrates into his discussion the results of recent studies, bringing into sharp focus topics of current bee research. These include the exquisite architecture of the nest and its relation to bee physiology; the intricate division of labor and the relevance of a temporal caste structure to efficient functioning of the colony; and, finally, the life-death struggles of swarming, supersedure, and mating that mark the reproductive cycle of the honey bee. The Biology of the Honey Bee not only reviews the basic aspects of social behavior, ecology, anatomy, physiology, and genetics, it also summarizes major controversies in contemporary honey bee research, such as the importance of kin recognition in the evolution of social behavior and the role of the well-known dance language in honey bee communication. Thorough, well-illustrated, and lucidly written, this book will for many years be a valuable resource for scholars, students, and beekeepers alike.

This book was released on 2010-02 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Food, Conservation, and Energy Act of 2008 directed the U.S. Dept. of Agr. to conduct a 1-year study to assess the extent of areas with limited access to affordable and nutritious food, identify characteristics and causes of such areas, consider how limited access affects local populations, and outline recommend. to address the problem. This report presents the findings of the study, which include results from two conferences of national and internat. authorities on food deserts and a set of research studies. It also includes reviews of existing literature, a national-level assessment of access to large grocery stores and supermarkets, analysis of the economic and public health effects of limited access, and a discussion of existing policy interventions.

Book excerpt: Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
Download or read book A Framework for Assessing Effects of the Food System written by National Research Council and published by National Academies Press. This book was released on 2015-06-17 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.
