RURAL BIOMASS ENERGY IN CHINA: A brief introduction Zhou Nan NO.1 +NO.1 +NO.2 +… =NO.1 UNCCC in Copenhagen: 40%~45% by 2020 ? GENERAL BACKGROUND “Exploration and utilization of renewable energy is the only way to deal with the increasingly severe problems of energy shortage and environmental pollution, and it is also the only way to the sustainable development of our society.” —Pres. Hu Jintao One of the key energy conservation and renewable energy policies is to promote rural biomass energy. WHY it matters? 1 over half of China is rural 2 huge energy demand VS. unbalanced energy consumption structure 3 abundant but least developed …… HOW TO USE? LET’S LEARN SOME KNOWLEDGE FIRST! GENERAL BACKGROUND ABOUT RURAL BIOMASS ENERGY CATEGORY: ANIMAL WASTE Agricultural waste (or residues) CURRENT USAGE: Situation A : stalks or wood are burned to heat or cook; animal waste as fertilizer or to produce biogas Situation B : POLLUTION!!! CAN’T THEY SEE THESE ARE RENEWABLE ENERGY? LOTS AND LOTS OF ENERGY??? YES!

Reference: * * * Subsequently we discuss the relation between water management and globalisation of trade from a product perspective, a governmental perspective and a business perspective. We focus all the time on developing understanding of the relation between water, production chains and trade. Finally we will make the step from concept to practice.

The translation of new understanding into policy is a trajectory ahead. Background materials can be freely downloaded from . Further, the following book is recommended: Hoekstra, A.Y. and Chapaga
