A persistent fear of diminishing phosphorus reserves has pushed mining companies to search far and wide for new sources. From April 2007 to August 2008, the price of phosphate, a necessary ingredient in fertilizer, increased nearly 950 percent, in part due to the idea that phosphate production had peaked and would begin diminishing. Before prices came back down, prospectors had already begun looking for deep sea phosphate reserves around the world.
Companies identified phosphate deposits on the ocean floor and are fighting for mining rights around the world. While several operations are proposed in the Pacific islands, New Zealand and Mexico rejected attempts at offshore phosphate mining in their territory.
This means southern African reserves – created in part by currents carrying phosphate-rich water from Antarctica – are the new center of debate. Namibia owns identified seabed phosphate deposits, and the country has recently flip-flopped about whether to allow mining. A moratorium was in place since 2013, but in September the environmental minister made the controversial decision to grant the necessary licenses. Since then, public outcry forced him to set those aside.
The former general project manager of Namibian Marine Phosphate (Pty) Ltd, a company that applied to mine in Namibia, told IPS that environmental groups and fisheries proved to be a loud and organised opposition. He predicted the debate in South Africa would be just as difficult for mining companies to win with no precedent for such mining.
Adnan Awad, director of the non-profit International Ocean Institute’s African region, said, “There is generally this anticipation that South African processes for mining and for the policy around some of these activities are setting a bit of a precedent and a bit of a model for how it can be pursued in other areas.”
Three companies, Green Flash Trading 251 (Pty) Ltd, Green Flash 257 (Pty) Ltd and Diamond Fields International Ltd., hold prospecting rights covering about 150,000 square kilometers, roughly 10 percent, of the country’s marine exclusive economic zone.
The law firm Steyn Kinnear Inc. represents both Green Flash 251 and Green Flash 257. “Currently it does not seem as if there is going to be any progress, and there is definitely not going to be any mining right application,” Wynand Venter, an attorney at the firm, said, calling the project “uneconomical.” Venter said the Green Flash companies received drill samples, which showed current prices could not sustain seabed phosphate mining.
This leaves Diamond Fields as the only remaining player in South African waters. The company announced in a January 2014 press release that it received a 47,468 square kilometer prospecting right to search for phosphate. The act of offshore mining requires a vessel called a trailing suction hopper dredger, which takes up seafloor sediment and sends waste back into the water column.
Environmentalists argue that not only would phosphate mining destroy marine ecosystems, but it would also lead to continued overuse of fertilizers and associated pollution. They call for increased research into phosphate recapture technology instead of mining.
“We could actually be solving the problem of too much phosphates in our water and recapturing it. Instead we’re going to destroy our ocean ecosystems,” John Duncan of WWF-SA said. “It amounts to a kind of bulldozer that operates on the seabed and excavates sediment down to a depth of two or three meters. Where it operates, it’s like opencast mining on land. It removes the entire substrate. That substrate become unavailable to fisheries for many years, if not forever,” Johann Augustyn, secretary of the South African Deep-Sea Trawling Industry Association, said.
In addition to direct habitat destruction, environmentalists argue the plume of sediment released into the ocean could spread out to smother additional areas and harm wildlife.
Mining opponents also worry offshore mining would negatively impact food production and economic growth. Several thousand subsistence farmers live along South Africa’s coast, and the country’s large-scale fishing industry produces around 600,000 metric tonnes of catch per year.
“[Mining] may lead to large areas becoming deserts for the fish populations that were there. If they don’t die off, they won’t find food there, and they’ll probably migrate out of those areas,” Augustyn said.
While the fishing and coastal tourism industries account for slightly more than 1.4 billion dollars of GDP, the potential economic benefits from marine mining remain unclear. There are no published estimates for job creation, but Namibian Marine Phosphate’s proposal said it would lead to 176 new jobs, not all of them local.
“The benefits are not coming back to the greater South African community,” Awad said. “African countries generally have been quite poor at negotiating the benefits through multinational companies’ exploitation of coastal resources.”
South Africa is one of only three African nations – along with Namibia and Seychelles – implementing marine spatial planning. This growing movement toward organised marine economies balances competing uses such as oil exploration, marine protected areas and fisheries. Earlier this year, the Department of Environmental Affairs, DEA, published a draft Marine Spatial Planning Bill, the first step toward creating marine-specific legislation.
According to government predictions, a properly managed marine economy could add more than 12.5 billion dollars to South Africa’s GDP by 2033. What part mining will play in that remains to be seen.
