New study argues need for dual nutrient strategy to improve aquatic ecosystems
Excess phosphorus and nitrogen produced by human activities on neighboring land is making its way into our coastal waters and degrading both water quality and aquatic life. Although historically the priority has been to control phosphorus, Professor Hans Paerl, from the University of North Carolina in the US, argues that nitrogen imbalance is equally damaging. He adds that a dual nutrient strategy – tackling both phosphorus and nitrogen surplus - is necessary to manage effectively this nutrient over-enrichment and resulting habitat degradation of coastal waters in the long-term. His perspective1 is published online in Springer’s journal Estuaries and Coasts.
