The book summarizes actual and/or relative environmental impacts resulting from existing and emerging agricultural production technologies, as practised in the USA. Case studies of environmental impacts of agricultural practices are discussed in one chapter, while separate chapters consider water and soil, air quality, noise and waste impacts. Air pollutants from cultivation operations, burning, agricultural vehicles, harvesting and grain handling, pesticide applications, wind erosion etc. are all considered. Noise produced by agricultural activities and exposure patterns for agricultural workers are examined. An annotated bibliography is included for the environmental impacts discussed in the text. Emerging agricultural production technologies such as nitrogen fixation, genetic engineering, plant growth regulation, erosion control, water management and waste utilization etc. are also compared for efficiency and environmental impacts.

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.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

The development of sustainable agricultural systems is an imperative aspect of any country, but particularly in the context of developing countries. Lack of progress in these initiatives can have negative effects on the nation as a whole. Agricultural Development and Food Security in Developing Nations is a pivotal reference source for the latest scholarly material on promoting advancements in agricultural systems and food security in developing economies. Highlighting impacts on citizens, as well as on political and social environments of a country, this book is ideally designed for students, professionals, policy makers, researchers, and practitioners interested in recent developments in the areas of agriculture.

This publication is based on Water for people - water for life, the UN World Water Development Report - UNESCO-WWAP 2003 where it appears as chapter 8 - securing food for a growing population. The report was jointly published by UNESCO and Berghahn Books and a slightly modified version of chapter 8 of the report is reproduced here.

"The assessment builds on the work of the Livestock, Environment and Development (LEAD) Initiative"--Pref.

This book offers an up-to-date review of our current understanding of climate change in the North Sea and adjacent areas, as well as its impact on ecosystems and socio-economic sectors. It provides a detailed assessment of climate change based on published scientific work compiled by independent international experts from climate-related disciplines such as oceanography, atmospheric sciences, marine and terrestrial ecology, using a regional evaluation and review process similar to that of the Intergovernmental Panel on Climate Change (IPCC). It provides a comprehensive overview of all aspects of our changing climate, discussing a wide range of topics including past, current and future climate change, and climate-related changes in marine, terrestrial and freshwater ecosystems. It also explores the impact of climate change on socio-economic sectors such as fisheries, agriculture, coastal zone management, coastal protection, urban climate, recreation/tourism, offshore activities/energy, and air pollution.

"Sustainability is at the heart of FAO's new Strategic Framework and is the specific focus of Strategic Objective 2, which aims at sustainably increasing the provision of goods and services from agriculture, forestry and fisheries. This report is the outcome of intensive consultations and discussions aimed at developing a common approach to FAO's work on sustainability. That process was conducted in a climate of cross-sectoral collaboration that drew on the contributions of leading FAO and external specialists in crops, livestock, forestry, capture fisheries, aquaculture and natural resources. The report provides the vision, the key principles and indications on the way forward to transition towards sustainable food and agriculture. It builds on the Organization's long experience in developing sustainability concepts, approaches and tools, and offers a common platform for a vision of the agriculture sector and of the inter-sectoral synergies that will eventually make agriculture more productive and sustainable."--Publisher's information.

Since the 1960s, the world's population has more than doubled and agricultural production per person has increased by a third. Yet this growth in production has masked enormous hidden costs arising from widespread pesticide use - massive ecological damage and high incidences of farmer poisoning and chronic health effects. Whereas once the risks involved with pesticide use were judged to be outweighed by the potential benefits, increasingly the external costs of pesticides, to environments and human health, are being seen as unacceptable. In response to this trend, recent years have seen millions of farmers in communities around the world reduce their use of harmful pesticides and develop cheaper and safer alternatives. The Pesticide Detox explores the potential for the phasing-out of hazardous pesticides and the phasing-in of cost effective alternatives already available on the market. This book makes clear that it is time to start the pesticide detox and to move towards a more sustainable agriculture.

In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.
