Air Emissions from Animal Feeding Operations


Book Description

Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.

Growth and Evolution in China's Agricultural Support Policies


Book Description

China is perhaps the most prominent example of a developing country that has transitioned from taxing to supporting agriculture. In recent years, Chinese price supports and subsidies have risen at an accelerating pace after they were linked to rising production costs. Per-acre subsidy payments to grain producers now equal 7 to 15 percent of those producers' gross income, but grain payments appear to have little influence on production decisions. Chinese authorities began raising price supports annually to bolster incentives, and Chinese prices for major farm commodities are rising above world prices, helping to attract a surge of agricultural imports. U.S. agricultural exports to China tripled in value during the period when China's agricultural support was accelerating. Overall, China's expansion of support is loosely constrained by World Trade Organization (WTO) commitments, but the country's price-support programs could exceed WTO limits in coming years. Chinese officials promise to continue increasing domestic policy support for agriculture, but the mix of policies may evolve as the Chinese agricultural sector becomes more commercialized and faces competitive pressures.

Publicly Funded Agricultural Research and the Changing Structure of U.S. Agriculture


Book Description

The U.S. Department of Agriculture (USDA) requested that the Board on Agriculture and Natural Resources of the National Research Council (NRC) convene a panel of experts to examine whether publicly funded agricultural research has influenced the structure of U.S. agriculture and, if so, how. The Committee to Review the Role of Publicly Funded Agricultural Research on the Structure of U.S. Agriculture was asked to assess the role of public-sector agricultural research on changes in the size and numbers of farms, with particular emphasis on the evolution of very-large-scale operations.
