A dispute over Western Saharas phosphate reserves could disrupt food production around the globe.
Aided by the longest conveyor belt in the world, a steady stream of chalky white powder emerges on the North African coast from deep within the desert. The belt, its presence betrayed by the bright windswept powder scattered around it on the brown earth below, travels 61 miles across the rugged terrain of Western Sahara, from the mines of Bou Craa to Port El Aain, where massive ships transport its contents across the globe.
The white powder is phosphate rocka commodity both valuable and vital. Without it, humanitys growing population couldnt feed itself. Phosphate, along with nitrogen, is one of the two most necessary components of synthetic fertilizer. But unlike nitrogen, which makes up 78 percent of the atmosphere, phosphate is a finite resource. And theres no way to manufacture it.

This political conflict, like the natural resource issues tangled into it, has remained obscure on the global front. But as other countrys domestic reserves of phosphate become more costly to extract in the coming decades, this disputed region could have more of a monopoly over phosphate than OPEC, the Organization of the Petroleum Exporting Countries, has over oilwhich has major implications for the future dynamics of food and its availability in the developing world.
In the 1960s, the widespread use of synthetic fertilizer, part of the Green Revolution, allowed millions of people who would have otherwise starved to be fed by dramatically expanding the land suitable for agriculture around the world. This was driven by the Haber process, which allows atmospheric nitrogen to be converted into a form biologically available for crops. But for any increase in nitrogen in soils, life also requires a commensurate increase in phosphorus, which is mined in the form of phosphate from geologic deposits around the world. The demand for mined phosphate skyrocketed.
No matter how impressive technological advances become, a Haber-like technique for creating phosphate will never exist There is a fixed amount in the Earth, its stuck in the ground, and the only way to get it is to mine it. So now theres a controversy about how much phosphate remains in the world, and how its distribution will affect food production in the future.
Our mining equipment for mineral resources exploitation has been greatly welcomed in world market, and has the benefits of optimum adaptation to the geological and technical requirements of earthworks and surface mining operations, low investment, high availability, simple maintenance, low.
A great deal of this uncertainty likely comes from the regions tense political situation. At the center of the conflict are the Sahrawi people, who have inhabited Western Sahara since before colonial timesa fact that Morocco contestsand have been fighting for the right to self-determination since Spain agreed to allow Morocco and Mauritania to split the area in 1975. Mauritania later abandoned their claim to the region.
According to Zunes, the Moroccan government squashes any hint of Sahrawi nationalism, follows foreigners, and bans the press. The United States, Moroccos long-time ally, has acknowledged many of these issues in the State Departments most recent human-rights report. Much of the native population now lives in Algerian refugee camps.
How phosphate is mined and processes Mining Sedimentary phosphate tends to be found in loose sediment, so it can be mined with dredge lines or picks and shovels. In Florida, the phosphate is found mainly in one layer of clay and sand thats about 10-20 feet thick, and 15-50 feet below the surface.
