Water Food Energy Nexus In China
Final report of Water Resource Management
MEM 2012: Xiangzi Wang
Energy, water, and food are intrinsically connected. Population growth, economic development and changes of lifestyle have led to increasing demand of water, food and energy. An estimated 70% of freshwater are used in agricultural production globally, according to Melissa D. Ho, senior policy advisor for the Bureau for Food Security at the U.S. Agency for International Development (USAID).(Lane, 2012) The remaining 20% goes for industry, and 10% for household use. Water is used as both non-renewable energy and renewable energy. For non-renewable energy, water is used as fuel production, thermoelectric cooling, oil recovery improvement, mining, transportation etc. Water is also used as renewable energy sources such as biomass, geothermal, solar, wind, and hydropower. (Figure 1)(Cramwinckel, 2010) What’s more, water is core resources for food production. Water used in irrigation supports human to be alive. Water related soil problem impacts the production of crops. Water scarcity can directly lead to a result of food security. With large amount of population, how to feed people in earth and give them clean drinking water have become challenges. In most of developing countries, these problems are more significant. Achieving water, energy and food security, and consequently reducing hunger and eradicating poverty, is a central future challenge that is possible even under difficult and challenging global economic conditions.

The rapid economic development of China brings challenges to China’s resources. 1/4 of the world's population is concentrated in China, but its available arable land, oil and water ownership rate are extremely imbalance compared to its population. For any country which wants to be self-sufficiency, natural resources are critical. But the plight of China is particularly serious, not...
