Protection, expansion and development of estuarine nature

By giving the Scheldt and its tributaries more space, we restore their ecosystem. This gives nature a solid boost and helps us to the European conservation objectives. Ebb and flow create a unique tidal natural environment that accommodates numerous special plants and animals. Areas that are not affected by the tides are turned into wetlands. These absorb the water during heavy rainfall, only to release it again very slowly in periods of drought.

River nature to enjoy

The natural environment in the Sigma Plan areas is connected to the river. Tidal mudflats, marshes and wetlands all act like sponges. They absorb water and therefore prevent flooding. They are also the perfect habitat for a wide variety of animals and offer beautiful landscapes to walk or cycle through.

More life in the water

We provide 9,028 hectares of nature development. That’s 18,056 football pitches! We aim to attract 110 target species, including great bitterns, beavers, great crested newts and even otters.

Rare plants and animals

The Sigma Plan helps to meet the conservation objectives of Natura 2000, the European network of nature protection areas. Step by step, we want to protect valuable plants and animals, and their habitats, and develop and restore them where necessary.

Better quality of life

By developing more nature, we contribute to better water and air quality, recreational opportunities, healthier fish stocks ... And several projects leave room for agriculture as well as nature.
