Phosphorus deficit may disrupt regional food supply chains

Phosphorus-based fertilizer is essential in modern agriculture. In regions with high population growth, more phosphorus will be needed to produce more food. A new study shows that world regions with high population growth rates are also the regions with the highest phosphorus deficit. It also quantifies the environmental impact of a business-as-usual scenario in the phosphorus supply chain to 2050 and identifies alarming rates of pollution and greenhouse gas emissions associated with the phosphorus supply.
