Safeguards of Rural Water Security Based on Public Goods Theory

Underground water is the main water source for rural residents in China and the safety of drinking water in rural areas becomes one of the most vital and practical livelihood issues. The number of people drinking surface water is roughly equal to that of underground water in the western and eastern region,while the number of people drinking underground water is 2. 5 times of that of surface water in the central region. As a whole,the drinking water source in rural areas is extremely unsafe because of the poor water quality and water sources pollution. Some protection measures on water source security in rural areas is discussed based on the theory of public goods,mainly including undertaking responsibility for rural water security by government,improving laws and regulations for rural water source protection,and encouraging rural residents to participate in safe water supplying.
