Rehabilitation of natural ecosystems 

The world's rivers and lakes are polluted by agricultural, industrial and domestic wastes. Wetlands are still being drained for agriculture and grazing or filled for urban development and infrastructure. The natural functions of rivers, lakes and coastal waters as vital aquatic ecosystems and of wetlands as nutrient absorbers are gradually being destroyed.
 
COWI is a leader in this field and has planned and managed the rehabilitation of some of the largest wetlands and ecosystems in Northern Europe. The rehabilitation of natural ecosystems requires knowledge of the area's cultural history, the use of the land throughout time and the intangible values of the nature in combination with experience in appropriate technical solutions.
