The difficulties of ＂polluter pays＂ policy in agricultural pollution in UK and methods to improve it

Agricultural wastes poll,tion became serious after great improvement in technology and the encouragement of production for the government since the end of the World Wai Ⅱ. Economists and environmental scholars suggested that ＂polluter pays＂ policy be employed in agricultural pollution control. However, it was hard to implement ＂polluter pays ＂ policy alone in agricultural wastes pollution.In practice, there were two social faCtors which contrih,ted to the improvement of water quality in the southwest of United Kingdom. One method is to communicate with farmers and then give farmers some advice or exhortation on facilities and management. The other method is to set up a telephone hotline for public to report water quality and probable pollution. Therefore, the consideration and combination of social factors in the control of agricultural wastes pollution are necessary, and important. Edueation of basic natural sciences relevant to agricultural pollution, system management of agricultural pollutants and laws relevant to agricultural pollution is suggested to be the third .social factor that British government can consider.
