This paper reviews the latest information and perspectives on global phosphorus scarcity. Phosphorus is essential for food production modern agriculture currently sources fertilizers from finite phosphate rock. The 2008 fertilizer price spikes triggered increased concerns regarding depletion timeline of rock reserves. While estimates range 30 to 300 years are shrouded by lack publicly available data substantial uncertainty, there a general consensus that quality accessibility remaining...
Phosphorus security is emerging as one of the twenty-first century's greatest global sustainability challenges. has no substitute in food production, and use phosphate fertilizers past 50 years boosted crop yields helped feed billions people. However, these advantages have come at a serious cost. Mobilizing rock into environment rates vastly faster than natural cycle not only polluted many world's freshwater bodies oceans, but also created human dependence on single nonrenewable resource....
The framework presented in this paper offers an alternative starting point for transdisciplinary research projects seeking to create change. begins at the end: it distinguishes three distinct 'transdisciplinary outcome spaces' and proposes articulating their content purposive projects. Defining upfront desired improvements has profound implications how is conceived, designed, implemented evaluated. Three key realms of spaces are distinguished – situation, knowledge, learning elaborated: (1)...
Food systems depend on reliable supplies of phosphorus to fertilize soils. Since 2020, a pandemic, geopolitical disputes, trade wars and escalating fuel prices have driven >400% increase in commodity prices, contributing the current food crisis. The Russia-Ukraine conflict has disrupted phosphate further. Concurrently, losses freshwaters, through insufficient municipal wastewater treatment inappropriate fertilizer use land management practices, are significant threat water quality...
Abstract 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,...
Phosphorus underpins the world’s food systems by ensuring soil fertility, maximising crop yields, supporting farmer livelihoods and ultimately security. Yet increasing concerns around long-term availability accessibility of main source phosphorus—phosphate rock, means there is a need to investigate sustainable measures buffer against long short-term impacts global phosphorus scarcity. While timeline scarcity contested, consensus that more efficient use recycling required. agricultural sector...
The chaotic distribution and dispersal of phosphorus (P) used in food systems (defined here as disorderly disruptions to the P cycle) is harming our environment beyond acceptable limits. An analysis stores flows across Europe 2005 showed that high fertiliser inputs relative productive outputs was driving low system efficiency (38 % overall). Regional imbalance (P surplus) losses were highly correlated total animal densities, causing unnecessary accumulation soils rivers. Reducing regional...

Without phosphorus, we could not produce food. Farmers need access to phosphate fertilizers achieve the high crop yields needed feed world. Yet growing global demand for phosphorus surpass supply in coming decades, and world currently largely relies on non-renewable rock that is mined only a few countries. Morocco alone controls 75% of remaining reserves, including those conflict territory Western Sahara. While some argue market will take care any scarcity, price fails account far-ranging...
Changes in human diets, population increases, farming practices, and globalized food chains have led to dramatic increases the demand for phosphorus fertilizers. Long-term security water quality are, however, threatened by such increased consumption, because world's main source, phosphate rock, is an increasingly scarce resource. At same time, losses of from farms cities caused widespread pollution. As one major factors contributing demand, dietary choices can play a key role changing our...
Phosphorus is a critical agricultural nutrient and major pollutant in waterbodies due to inefficient use. In the form of rock phosphate it finite global commodity vulnerable price shocks sourcing challenges. Transforming toward sustainable phosphorus management involves local stakeholders. Conventional readings stakeholders may not reflect system complexity leaving difficult see stakeholder roles transformations. We attempt remedy this issue with novel analysis method based on five...
