Global Food Research Colloquium
Fertilizer Use in China: Why Is It So High, and What Can Be Done to Reduce It?
Professor David Abler, Ph.D., Agricultural, Environmental and Regional Economics and Demography, Penn State University
Tuesday, 17.05.2016, 16:15 to 17:45
On Tuesday, May 17th David Abler will present his research on fertilizer use in China in the Global Food Research Colloquium. The Colloquium has been organized by the Department of Agricultural Economics and Rural Development as a joint event with the Agricultural Economics Seminar.
China’s rates of agricultural fertilizer use per hectare are among the highest in the world, and fertilizer is a major contributor to water pollution, air pollution, and greenhouse gas emissions in China. Several explanations have been put forward for the high rates of fertilizer use in China, most of which do not stand up to close scrutiny. A number of pilot programs offering farmers information, technical assistance, and/or incentives to reduce fertilizer use have been tried, almost all of which have failed. This paper surveys these explanations and programs, identifies key unanswered research questions about fertilizer use in China, and offers programmatic suggestions for reducing fertilizer use based on the experience of other countries.
