Back in the early days of the FFC there was global concern about the level of phosphorous reserves with some analyses finding that reserves could be a low as 50 years (see the 2014 FFC Bulletin article ‘The future of phosphorus’). The good news is that a new analysis puts it at 400 years. “Our Phosphorus Future” has recently published a major report “A sustainable direction for phosphorus will lead to better food production, cleaner waters, healthier people and greater biodiversity” that updates the global phosphorus situation and provides a comprehensive analysis of how humanity needs to manage all aspects of phosphorus for a long term sustainable future.
