摘 要:1.Introduction to the challenges of water security Over the past two to three decades,international concern about global water security has been increasing,along with a need for a more holistic approach to deliver sustainable solutions that address the growing challenges of water management.Although a series of high-profile reports have been published on global water security during this period(e.g.,Ref.[1]),the challenges remain and—if anything—are becoming more extreme.Our planet has limited freshwater resources:The total global volume of water is 1.4 billion km^(3),but only 35 million km^(3) of this resource is freshwater,and much of it is locked in the form of ice.Thus,only 105000 km^(3) of fresh water is accessible for use as water supply,and 70% of all withdrawals of freshwater are currently used for agriculture,primarily for food production[2].
