Water and climate change: what do we mean?

What do we mean when we say: ‘We cannot afford to wait. Climate policy makers must put water at the heart of action plans’?

Climate delay is almost as dangerous as climate denial. Every country in the world must work more quickly.

Extreme weather events are making water more scarce, more unpredictable, more polluted or all three.

Humans need water to survive, as do all the systems we rely on: sanitation, healthcare, education, business and industry.

Action plans to tackle climate change need to be integrated across different sectors and coordinated across borders. And they must have one thing in common: safe and sustainable water management.

Learn more in the UN-Water Policy Brief on Climate Change and Water.

What do we mean when we say: ‘Water can help fight climate change. There are sustainable, affordable and scalable water and sanitation solutions’?

Fighting climate change will open up vast opportunities for the economy in many areas. We need to embrace circular production systems and use water much more efficiently.

As the global population grows, so does the demand for water, which depletes natural resources and damages the environment in many places. Solutions include protecting carbon sinks such as oceans and wetlands, adopting climate-smart agricultural techniques, and increasing the safe reuse of wastewater.

Water is our most precious resource – we must use it more responsibly. We must balance all of society’s water needs while ensuring the poorest people don’t get left behind.

What do we mean when we say: ‘Everyone has a role to play. It is surprising how many water actions anyone, anywhere can take to address climate change.’?

United Nations Secretary-General António Guterres said: “Warnings are necessary. But fear will not get the job done.”

Yes, climate change can feel scary and daunting. But there is one simple step you can take immediately that will make a big difference: don’t waste water.

Thousands of people are logging their climate actions on the United Nation’s ActNow website. Check out all the easy lifestyle changes that will help save the planet.

Preserving the “Earth’s Kidneys”

Preserving the “Earth’s Kidneys”

Wetlands are vital to the health of our planet. Like kidneys, which filter our blood to eliminate toxins, wetlands store, assimilate and transform pollutants before reaching the water table and waterways. They help control floods, mitigate droughts, naturally disinfect wastewater, and retain carbon. The Hubei province of China, known as the province of a thousand lakes, has 1.4 million hectares of wetlands. This territory serves as an ‘ecological kidney’ and also provides a habitat to 140 species of migratory birds. Human activity and climate change is threatening the territory. A UNDP project of wetland conservation is alleviating this threat.

Take good care of water

Take good care of water

In areas of Peru, a communications campaign is promoting ‘water culture’: creating a positive change in people’s water-use habits, such as reducing wastage and irrigating more efficiently, so that respect for this critical resource is embedded in the heart of the community.

One trillion trees

One trillion trees

The World Economic Forum has launched a global initiative to grow, restore and conserve 1 trillion trees around the world – in a bid to restore biodiversity and help fight climate change. The 1t.org project aims to unite governments, non-governmental organisations, businesses and individuals in a “mass-scale nature restoration”.

1t.org is designed to support the UN Decade on Ecosystem Restoration 2021-2030, led by UNEP and FAO. Learn more here.
