Phosphorus Peak

Mankind has used manure, seaweed, guano and other organic fertilizers for centuries to increase food production. It wasn’t until the mid-20th century that farmers began widespread use of inorganic fertilizer, which combines mined and synthetic chemicals. The chief components are nitrogen, phosphorus and potassium

Many have heard the expression "peak oil", the point here oil reserves begin to decline. Less well known is "peak phosphorus". Our dwindling supply of phosphorus, a primary component underlying the growth of global agricultural production, threatens to disrupt food security across the planet during the coming century. This is the gravest natural resource shortage you've never heard of.

Farmers treat their fields with phosphorus-rich fertilizer to increase the yield of their crops. However, arge amounts of this resource are lost from farm fields, through soil erosion and runoff. The world's reliance on phosphorus is an unappreciated aspect of the "Green Revolution," a series of agricultural innovations that made it possible to feed the approximately 4.2 billion-person increase in the global population since 1950. This massive expansion of global agricultural production required a simultaneous increase in the supply of key resources, including water and nitrogen. Without an increase in phosphorus, however, crops would still have lacked the resources necessary to fuel a substantial increase in production, and the Green Revolution would not have gotten off the ground.

By 2008, industrial farmers were applying an annual 17 million metric tons of mined phosphorus on their fields. Demand is expanding at around 3 percent a year -- a rate that is likely to accelerate due to rising prosperity in the developing world (richer people consume more meat) and the burgeoning bioenergy sector, which also requires phosphorus to support crop-based biofuels. Worldwide production of phosphate rock — the primary source of phosphorus in fertilizer — jumped from 40 million tons in 1960 to an estimated 191 million tons last year, according to U.S. Geological Survey data.

Because phosphate rock is roughly 11 percent phosphorus, that means companies produced about 21 million tons of the element in 2011. Of that, 95 percent is turned into fertilizer, according to Kathy Mathers, a spokeswoman for The Fertilizer Institute. In 2009, Australian scientists estimated that nearly 80 percent of phosphorus in fertilizer is wasted.

Our supply of mined phosphorus is running out. Many mines used to meet this growing demand are degrading, as they are increasingly forced to access deeper layers and extract a lower quality of phosphate-bearing rock (phosphate is the chemical form in which nearly all phosphorus is found). Some initial analyses from scientists with the Global Phosphorus Research Initiative estimate that there will not be sufficient phosphorus supplies from mining to meet agricultural demand within 30 to 40 years. The United States has only 12 phosphorus mines. The supplies from the most productive mine, in Florida, are declining rapidly -- it will be commercially depleted within 20 years.

The geographic concentration of phosphate mines also threatens to usher in an era of intense resource competition. Nearly 90 percent of the world's estimated phosphorus reserves are found in five countries: Morocco, China, South Africa, Jordan, and the United States. (In comparison, the 12 countries that make up the OPEC cartel control only 75 percent of the world's oil reserves.) This fact could spark international tension and even influence how countries attempt to draw their internal boundaries. Many of Morocco's phosphate mines are in Western Sahara, a disputed independent territory that is occupied by Morocco and the site of growing international human rights concerns. The United States exported phosphorus for decades but now imports about 10 percent of its supply, all from Morocco

Increased demand for fertilizer and the decreased supply of phosphorus exports will result in higher prices, significantly affecting millions of farmers in the developing world who live on the brink of bankruptcy and starvation. Rising fertilizer prices could tip this balance. Between 2003 and 2008, phosphate fertilizer prices rose approximately 350 percent.

The war for wealth

Afghanistan's immense mineral wealth is estimated to be worth around £2trn, according to the Kabul government. Afghanistan's mineral wealth extends over a huge range of valuable resources: iron, gold, copper, niobium (used in hardening steel), uranium, marble, cobalt, mercury, caesium, molybdenum (a metal which can withstand high temperatures and is used to make various alloys), and other rare earth minerals. The country has especially valuable deposits of lithium, the metal used in the world's batteries. Indeed, a Pentagon official is on record suggesting that Afghanistan could be "the Saudi Arabia of lithium".

As far back as 2008, China agreed a deal to develop the Aynak copper mine in Logar province. This is said to be the world's second largest deposit of high-grade copper. The Afghan National Police has deployed 1,500 officers to guard the mine. As part of its agreement to develop a massive copper mine in Aynak, the China Metallurgical Group Corporation (MCC) is being asked to build a 575-mile railway from the mine, south-east of Kabul. One branch would head to the Pakistani border, another in the opposite direction through the capital and connecting with the new Hairatan line in the north. The deals are not confined to minerals. In late December, China's state-owned National Petroleum Corporation (CNPC) won a contract for three oil fields in Zamarudsay, Kashkari, and Bazarkhami in the northern provinces of Sari Pul and Faryab, which will make it the first foreign company to exploit Afghan-istan's oil and natural gas reserves. The intention is that CNPC will build a refinery within three years, and this will be guarded by dedicated units of Afghan police and army.

Chinese state firms have also been involved with seven infrastructure projects, including roads in Kondoz and Jalalabad. They have also won contracts for telecommunications systems in Kandahar and Kabul. And last year, the Asian Development Bank announced it had allocated more than $200m for the development of the gas wells of Sheberghan, and an attendant pipeline.

Italy, Turkey and Germany are also actively pursuing deals. PricewaterhouseCoopers is advising the Ministry of Mines in Kabul, and the US bank JP Morgan is active, having put together a consortium that won rights to the Qara Zaghan gold deposits. An Indian consortium has secured the rights to two blocks in the huge Hajigak iron ore field, the other block going to a Canadian firm. The Afghan government is also negotiating with the Indian-led consortium that won the contract for the equally huge iron deposits at Tajigak in central Afghanistan for the companies to fund a 560-mile railroad – likely through Iran – to bring out the heavy ore. India will also contribute to the establishment of an Institute of Mines in Kabul, and last October signed a strategic partnership with Afghanistan.

China, Iran, Pakistan and India all have government or corporate plans for separate rail projects across Afghanistan. Turkmenistan is completing its own plans for another line, and it was Uzbekistan that built the first major rail link, a 47-mile line from the border town of Hairatan to Mazar-i-Sharif in the north of Afghanistan. "We would be able to import and export to Russia, Turkey, and even European countries," says Noor Gul Mangal, Afghanistan's deputy public works minister. Opening new transport gateways would also reduce Afghanistan's dependence on neighbouring Pakistan as its only link to sea ports.
