Dark nights?

Light has long been seen as a positive force in our environment. Artificial light allowed us to overcome nature’s darkness. It is Enlightenment in its most concrete form.

Great Britain has big plans and has invested millions in recent years, particularly in Scotland. Dutch companies see tidal energy as an important […]


Years of dredging the shipping lane to Antwerp, has made the canals in the Westerschelde deeper. This has increased the flow rate of the water while the estuary’s storage capacity diminished. Coastal defense and biodiversity suffer from the strong currents in the Westerschelde. Extensive deepening and widening of the navigation channel reinforce this. The ecology […]
