Outline <ul><li>Physical resources and the need to improve overall efficiency </li></ul><ul><li>Development models leading to the circular economy </li></ul><ul><li>The Circular Economy Promotion Law and its relationship to industrial ecology </li></ul><ul><li>Implications for improving resource productivity based on circular economy and industrial ecology </li></ul>
    3. 3. Great resource productivity – land, labor, and capital = the Chinese economic miracle <ul><li>World’s largest population with world’s fastest growing economy: </li></ul><ul><li>Forty fold increase in international trade between 1978 and 2003. </li></ul><ul><li>Since 2002, China has overtaken the US to receive the most foreign investment annually of any country. </li></ul>
    4. 4. The endowment of resources in China is small and distributed unevenly <ul><li>China has: </li></ul><ul><li>1.8% of the world’s total oil reserves, </li></ul><ul><li>0.7% of natural gas, </li></ul><ul><li>0.9% of iron ore, </li></ul><ul><li>5% of copper ore, and </li></ul><ul><li>2% of aluminum </li></ul>
    5. 5. With regard to per capita resources, China has: <ul><li>half the world average in mineral resources, </li></ul><ul><li>one-third in arable land and grassland, </li></ul><ul><li>one-fourth in water resources, </li></ul><ul><li>one-fifth in forest, </li></ul><ul><li>one-seventh in energy, and </li></ul><ul><li>only one-tenth in oil </li></ul>Information Office of the China State Council 2006
    6. 6. Example of rising consumption and declining resources <ul><li>Five fold increase in fish consumption/person in the past 25 years according to UN FAO </li></ul><ul><li>The catch of wild fish in the Yangtze has declined 75%. </li></ul><ul><li>China is the world’s largest producer of aquaculture grown food with fish production increasing approx. 250% in 18 years </li></ul><ul><li>China is the only country in which aquaculture provide more fish and aquatic food than wild fisheries. </li></ul>Liu and Diamond – Nature Vol 435 June 2005

National People’s Congress – Environmental Protection & Resources Conservation Committee <ul><li>On the need for modernization: </li></ul><ul><li>“ China has been facing serious environmental and resources problems with its economic development since the 1980s, mainly due to inefficient use of resources” </li></ul>
    10. 10. “ Industrial ecology is the study of the flows of materials and energy in industrial and consumer activities, of the effects of these flows on the environment, and of the influences of economic, political, regulatory, and social factors on the flow, use, and transformation of resources.” Defining Industrial Ecology Robert White NAE 1994
