Phosphate rock is on EU Critical Raw Materials list- Linked to world food security and price instability- Europe > 90% dependent on imports- Geo-political concentration of reserves
Without phosphate fertilisers we could feed around 1/5 of the world populationAdapted from Dawson et al., Food Policy 2011: http://www.sciencedirect.com/science/journal/03069192

Environmental impacts- Eutrophication- Ammonia emissions- Planetary boundaries
Phosphorus is the first cause of EU Water Framework Directive quality failure (other than morphology)
