According to the Uinted Nation’s annual World Water Development Report 2018 which highlighted the need to use nature to combat the challenges of a growing population and climate change.
Deforestation, intense farming methods and urbanization are issues bedeviling climate change, while climate change is making parts of the world more susceptible
The UN said nature has a variety of untapped solutions to help meet these challenges.
The report highlighted that the demand for water is increasing in developing countries, while simultaneously access is being put at risk by human development and climate change.
The Director-General of UNESCO, Audrey Azoulay, said new solutions is needed in managing water resources so as to meet emerging challenges to water security caused by population growth and climate change.
He said If nothing is done about five billion people will be living in areas with poor access to water by 2050.
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.
The report makes the case for working with nature to support a “resource-efficient and competitive circular economy”. This mean mimicking natural processes such as soil moisture retention, building large new wetland areas, and restoring floodplains or green roofs.
Incorporating techniques found in natural can have environmental, social and economic benefits and help achieve the vital Sustainable Development Goals into the 2020s, it concludes.
It’s hoped that a blend of both green and grey investments can increase water efficiency in a cost-effective way.
