On World Water Day, March 22nd, the UN published a new report: The United Nations World Water Development Report 2020. The report draws a gloomy picture of the climate and our future.
As the planet warms, water has become one of the main ways in which we experience the changing climate. Yet, water is rarely brought up in the climate debate or in the international climate agreements, even though it plays a significant role in issues such as food security, production of energy, poverty reduction and economic development.
This falls into line with our strong opinion that water deserves a lot more attention on the global climate agenda; including the debates on energy production and health in general. Water is the source to all life and development on the planet, and wise management can have immense impact on how we address the 17 UN goals on sustainable development.
We need to spread the word about existing technologies
The report states that, even though we need to focus on research and development, it is just as important to implement the already known and well-proven technologies. There are plenty to choose from, and with sufficient awareness and education, this is the way we can - and should - change our path.
80% of all human-induced wastewater is discharged directly into nature without any prior treatment. This should be collected, treated, and the remaining sludge should be utilised for energy production. If the treated water can then be discharged into a nearby area, expenses can be cut on the energy bill. Discharging into a nearby area can create a constructed wetland contributing with biodiversity and recreative areas. Through controlled seeping to the groundwater, cities are not in danger of sinking due to overexploited groundwater reserves, which is an issue many larger cities are dealing with today.
