Wetlands are areas that remain in flooded conditions or with soil saturated with water for considerable periods of time. By being regularly covered with water, the soil becomes saturated, devoid of oxygen, and this gives rise to a hybrid ecosystem between aquatic and terrestrial.

Wetlands are a source of health and wealth. They provide us with freshwater, guarantee our food supply and help maintain the planet's biodiversity. They are essential ecosystems for many amphibians and reptiles and for the reproduction and migration of birds.
