China’s huge investment on water facilities: an effectiveadaptation to climate change, natural disasters,and food security

China’s huge investment on water infrastructure for sustainable water use, followed by recently frequent natural disasters, caused worldwide concerns, i.e., continuously published by Nature and Science. Most researchers emphasized challenges on this investment; yet, we argue that the 2011-plan, targeting reservoirs, wells, irrigation systems, inter-basin water transfer projects, is the most effective adaptation to climate change, drought and flooding, as well as food security. This provides a good case of water management and development, particularly for the current uneven water resources and food security by climate change.
