Most of us only think about floods or droughts when they disrupt daily life, empty taps, damaged roads or rising food prices.

But long before crises occur, wetlands and river systems have been working quietly to shield us from the worst effects.

Wetlands are often called “nature’s sponge” because they can hold vast amounts of water during heavy rain.

This storage slows water movement, reducing the force that causes flash flooding in towns and villages.

After storms pass, wetlands release water slowly into rivers and underground reservoirs, keeping supplies available for longer. This natural rhythm is one of our strongest protections against extreme weather.

Rivers also play a crucial role. Natural riverbanks lined with indigenous plants stabilise soil and prevent erosion, the wearing away of riverbanks that can cause dangerous overflows and damage farmland.

When rivers are straightened, paved or stripped of vegetation, water flows faster and more violently, increasing downstream risks.

As climate change brings more unpredictable rainfall, we will depend on these ecosystems even more.

Wetlands and river systems help prevent disasters, store water for dry seasons and keep landscapes stable. They act as natural insurance, and unlike engineered structures, they repair and maintain themselves when given the chance.

Protecting these landscapes is about more than wildlife. It is about safeguarding homes, infrastructure and local economies. Without healthy wetlands and rivers, communities become more vulnerable and recovery costs rise.

Practical actions you can take:

• Avoid building or paving over natural wetlands or floodplains.
• Plant indigenous vegetation along riverbanks and in gardens.
• Support local campaigns that protect natural water systems.
• Capture rainwater at home to reduce stormwater pressure.
