Phosphorus is one of the key nutrients necessary to human, animal and plant life. The finite resource must be used more effectively. Sustainable Phosphorus Management: A Global Transdisciplinary Roadmap provides up-to-date information on global phosphorus flows and identifies options to improve phosphorus efficiency and sustainability.
A detailed projection of phosphorus production by two Australian researchers indicates that world phosphate rock production will most likely peak in 2027. Phosphorus is a finite resource and cannot be substituted for agricultural uses. Without the use of phosophrus in fertilisers it would be difficult to provide sufficient food for an expanding world population.
