We make floods more likely

We can have a big impact on how common floods are.

A flood happens when water reaches the river more quickly than normal.

We make floods more likely by taking away forest with its porous soil, farming the land, tarmacing and concreting the land surface in towns and adding drains that carry water directly to rivers.
