Global phosphorus scarcity: identifying synergies for a sustainable future.

摘要: Global food production is dependent on constant inputs of phosphorus. In the current system this phosphorus not predominantly derived from organic recycled waste, but to a large degree phosphate-rock based mineral fertilisers. However, phosphate rock finite resource that cannot be manufactured. Our dependency therefore needs addressed sustainability perspective in order ensure global supplies for growing population. The situation made more urgent by predictions that, example, consumption intensive foods and demand biomass energy will increase. scientific societal debate has so far been focussed exact timing peak when total depletion reserves occur. Even though these events important, all dimensions scarcity need manner which acknowledges linkages other sustainable development challenges takes into consideration synergies between different measures. Many measures have positive impacts challenges; shifting diets plant-based would only reduce consumption, also greenhouse gas emissions, nitrogen fertiliser water consumption.
