What has climate change got to do with water?
Our climate is changing at an alarming rate and it’s making it even harder for the world’s poorest people to get clean water. More frequent and extreme flooding is polluting fragile water sources; longer droughts are drying up springs. People need a reliable supply of water that keeps pumping through flood, drought and natural disaster. Because with clean water, they can stay disease free, go to school, earn a living and be better prepared for whatever the future brings.
Climate change can seem abstract and overwhelming, but it’s real and it’s happening now.
Did you know that 2019 was the second hottest year ever? The last decade was the warmest one yet. Globally, temperatures are rising, which means the weather is becoming more extreme, resulting in either too much or too little water. In fact, a staggering 90% of all natural disasters are water-related, and they're massively impacting people's lives.
We’re feeling the effects of too much water here in the UK as floods worsen and become more regular. In Australia, communities and wildlife have been impacted by too little water through extreme heat and catastrophic bushfires.
But it’s the world's poorest people, in the countries that have done the least to contribute to climate change, who are worst affected. A shocking 1 in 10 people don’t have clean water close to home – and the climate crisis is only making that worse.
By 2040, 1 in 4 children will live in regions where water is dangerously scarce. Together, we need to take urgent action, to defend the right to clean water for everyone, regardless of where they live, and to protect our future generations, before it's too late
How does climate change affect people's access to clean water?
In countries like Bangladesh, Ethiopia and Mozambique, climate change is causing prolonged droughts. That means people have to walk further to find water. Often the only water available is dirty, which makes people sick. Drought also means farmers’ crops are more likely to fail and cattle risk dying, so they have less produce to sell and families have less food to eat.
Malawi, Pakistan and Timor Leste are some of the countries increasingly affected by flooding and least prepared to adapt to the extremities. Floods can destroy people’s crops, toilets and homes, and they can contaminate drinking water sources, damaging people’s livelihoods, their dignity, their safety and health.
What does WaterAid do to help the people worst affected by climate change?
We provide water services communities can rely on
A reliable source of clean water is the first line of defense against the impact of our changing climate on people’s lives and livelihoods. Together with supporters like you, we’ve been transforming millions of lives with clean water for decades.
We provide waterpoints and pipe networks that can withstand floods, so people continue to have clean and safe drinking water. And we help people monitor and manage their water supplies properly to meet their basic needs in times of drought.
We work with governments and businesses for bigger change
We share our knowledge with governments and the private sector to change even more lives. We work with governments to make sure access to clean water is at the heart of their climate adaptation and development plans.
But nowhere near enough government money is invested in helping people most vulnerable to climate change. Our research shows that in some of the poorest countries in the world, as little as $0.20 per person is spent each year on making water services climate resilient.
We're calling for an urgent tenfold increase in climate finance spent on getting sustainable, clean water to the people currently forced to live without, so they can cope with the effects of climate change.

Climate and WASH statistics
- In 2016, just 5% of total climate spending (PDF) – US$23 billion – was spent on adaptation globally, compared to almost $300 billion on renewable energy projects.
- Less than a third of all climate finance (PDF) reaches the least developed countries that need it most.
- Half of all countries receive less than $4 per person per year in climate finance for both climate mitigation and adaptation.
- Half of countries where more than 1 in 10 people do not have water close to home get less than 77c per person per year in climate finance for water service adaptation.
- The United Nations Environment Programme estimates that, even if the average global temperature rise is kept to 2°C, poorer countries will need $70 billion to $100 billion (PDF) every year until 2050 to help them adapt.
- Limiting global warming to 1.5°C, compared to 2°C, may up to halve the proportion (PDF) of the population exposed to increased water stress caused by climate change, although this varies between regions.
- In the past decade, more than 90% of major disasters have been caused by floods, storms, heatwaves, droughts and other weather-related events that are expected to become more frequent and intense because of climate change.
