This system aims to bring about the most effective coordination of social, economic and ecological factors in agricultural practices. Key approaches include ecological planning at the landscape level, cycling system design at the ecosystem level, and the re-establishment of the importance of biodiversity. The social and economic environment favoured for ecoagriculture is important in order to enable its development. For the social environment, it is important to set up the necessary moral standards involved through educational, legislative and evaluation systems. For the economic environment, efficient government subsidy policies, an effective market system to deal with pollutant discharge, and efficient markets for the sale of ecologically-friendly products.展开更多
