We visit the communities in Chile restoring vital wetlands in cities and towns.

Chile’s urban wetlands are under pressure from rapid development, pollution and neglect, yet they play a crucial role in storing rainwater, supporting wildlife and reducing floods.

We visit the southern city of Valdivia where local communities have restored damaged wetlands by clearing rubbish, replanting native species and designing parks that work with nature rather than against it. Their efforts have transformed unsafe dumping grounds into thriving public spaces.

And in the major city of Concepción, residents work to restore wetlands to help fight flooding by reconnecting fragmented wetlands to allow them to do their original job.
