Paris sources reported that governments should focus on "greener" policies to improve the supply and quality of water as climate change and a growing global population threatens the water security of billions. Meanwhile the United Nations said in its 2018 World Water Development Report, the UN calculated that an estimated 3.6 billion people nearly half the global population live in areas where water can be scarce at least one month per year.



UNESCO Director General, Audrey Azoulay, at the presentation of the report in Brasilia stated "If we do nothing, some five billion people will be living in areas with poor access to water by 2050". She said "This report proposes solutions that are based on nature to manage water better. This is a major task all of us need to accomplish together responsibly so as to avoid water-related conflicts".

Moreover "Green" infrastructure also helps fight erosion, drought and flood risks while boosting soil quality and vegetation.
