"Unless something is done, the scarcity of phosphorous will cause problems of a global dimension. As early as 2035 it is calculated that the demand for phosphorus map outpace the supply," says Dana Cordell, who presented her thesis at the Department of Thematic Studies - Water and Environmental Studies, Linköping University, Sweden on the implications of phosphorus scarcity on global food security.
Phosphorous is extracted from phosphate rock, a non-renewable resource that is used almost exclusively in agriculture. Two thirds of the world's resources are in China, Morocco, and Western Sahara.
"The demand for phosphorus has increased and prices soared by 800 percent between 2006 and 2008," says Dana Cordell.
Cordell maintains that the shortage of phosphorus in not simply due to a drop in the availability of phosphate ore. Many of the world's farmers do not have enough purchasing power to be able to afford and use phosphorus-based fertilizer, which means their soil is becoming depleted. What's more, phosphorus use in the food system from mine to field to fork is currently so inefficient that only one fifth of the phosphorus in the rock that is mined actually makes its way into our food.
"There is a lack of effective international governance to secure long-term access to phosphorus for food production," says Dana Cordell, who adds that the way phosphorus resources are handled needs to be improved.
Phosphorus needs to be applied and management in agriculture more efficiently, we need to eat more vegetarian food, and increase efficiency throughout the food chain. At the same time we need to recover and reuse a large part of the phosphorus that exists in crop residues, food waste, manures human faeces and other sources.
"If nothing is done, food production runs the risk of a hard landing in the future, including further fertilizer price increases, increasing environmental effects of pollution, energy and resource consumption, smaller harvests, reduced farmer livelihoods and reduced food security," says Dana Cordell.
The dissertation is titled The Story of Phosphorus: Sustainability Implications of Global Phosphorus Scarcity for Food Security.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
