The answer is in nature

Water is an essential building block of life. It is more than just essential to quench thirst or protect health; water is vital for creating jobs and supporting economic, social, and human development.

Today, there are over 663 million people living without a safe water supply close to home, spending countless hours queuing or trekking to distant sources, and coping with the health impacts of using contaminated water, stated the United Nations (UN).

World Water Day is an international observance and an opportunity to learn more about water related issues, be inspired to tell others and take action to make a difference. Each year, UN-Water — the entity that coordinates the UN’s work on water and sanitation — sets a theme for World Water Day corresponding to a current or future challenge. The engagement campaign is coordinated by one or several of the UN-Water Members with a related mandate.

The 2018 theme for World Water Day is "Nature for Water".

This year’s theme explores how we can use nature to overcome the water challenges of the 21st century.

Environmental damage, together with climate change, is driving the water-related crises we see around the world. Floods, drought and water pollution are all made worse by degraded vegetation, soil, rivers and lakes.

When we neglect our ecosystems, we make it harder to provide everyone with the water we need to survive and thrive.

Nature-based solutions have the potential to solve many of our water challenges. We need to do so much more with ‘green’ infrastructure and harmonize it with ‘grey’ infrastructure wherever possible. Planting new forests, reconnecting rivers to floodplains, and restoring wetlands will rebalance the water cycle and improve human health and livelihoods.

Sustainable Development Goal 6 – ensuring availability and sustainable management of water and sanitation for all by 2030 - includes a target to halve the proportion of untreated wastewater and increase water recycling and safe reuse.

World Water Day is coordinated by UN-Water – the UN’s inter-agency collaboration mechanism for all freshwater related issues - in collaboration with governments and partners. 

QUICK FACTS

  • Globally, over 80% of the wastewater generated by society flows back into the ecosystem without being treated or reused. (Sato et al, 2013)
  • 1.8 billion people use a source of drinking water contaminated with faeces, putting them at risk of contracting cholera, dysentery, typhoid and polio. Unsafe water, poor sanitation and hygiene cause around 842,000 deaths each year. (WHO/UNICEF 2014/WHO 2014)
  • The opportunities from exploiting wastewater as a resource are enormous. Safely managed wastewater is an affordable and sustainable source of water, energy, nutrients and other recoverable materials.
