Resource And Environmental Impacts Of Trends In Us Agriculture

Originally published in 1982, this report explores long-term trends in demand for U.S. agricultural production, energy prices and agricultural technologies and their effect on natural resources such as land and water in the United States. Crosson and Brubaker also discuss possible policy modifications in order to lessen the environmental impacts expected to emerge from these trends. This title will be of interest to students of Environmental Studies.

This book describes trends in resources used in and affected by agricultural production (including natural, produced, and management resources), as well as the economic conditions and policies that influence agricultural resource use and its environmental impacts. Each chapter provides a concise overview of a specific topic with links to sources of additional information.

At the beginning of the 1970’s, global grain reserves were level and food prices were low however as the decade progressed crop production plummeted leading to a food crisis. Originally published in the aftermath in 1977, Crosson and Frederick set out to explore the ability of agricultural output to meet the global food demands of future generations. This study analyses how resources and environmental factors would affect food production in developing countries and the United States until the end of the 21st Century. The environmental impacts of land levels, fertiliser and pesticide use are explored in relation to the challenges of meeting food demands. This title will be of interest to students of environmental studies.

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 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.
