Reduction of Eutrophication

Credit: K.J. HesseFor many areas of the North-East Atlantic, a lingering decline of plankton variety and a steady increase in algal growth has been reported as a result of elevated nutrient levels. All of a sudden, exceptional and harmful algal blooms have been increasing in the North Sea. Deoxygenated black spots have spread across the tidal mud flats of the Wadden Sea threatening all bottom-dwellers. There is too much of a good thing in the sea, due to nitrogen inputs from land-based sources, such as agricultural run-off. Eutrophication problems will continue unless the excess nitrates from manure and fertiliser use, ammonia from lifestock and nitrogen oxide from vehicles are drastically reduced. So far, governments have missed their reduction targets. WWF helps develop and strengthen programmes to reduce nutrient inputs to the marine environment.
