Marange diamond mines pollute rivers, Zimbabwe


The Marange diamond fields are an area of widespread small-scale diamond production in Chiadzwa, Mutare West, Zimbabwe. Although estimates of the reserves contained in this area vary wildly, some have suggested that it could be home to one of the worlds richest diamond deposits.

Project Details and Actors
Project DetailsIt is hard to have a clear picture of the volume of diamonds mined at Marange. Both the KP civil society representatives and the Parliamentary Portfolio Committee on Mines were denied mine level data on statistics during separate visits early 2012. However government later revealed that projection of diamond output for 2014 was 14.5 million carats
Project Area (in hectares)200000

New Environmental Impact Assessment/Study
Development of AlternativesCompanies must stop disposing toxic waste into the river, rather they must invest into technology which prevents pollution

Activists want a complete overhaul of the current Environmental Manage Act to give the agency prosecuting authority and the setting up of an environmental pollution court staffed with judges with environmental law and impacts academic and professional backgrounds. They also want stiffer penalties for environmental crime perpetrators, including suspension and revocation of licences for regular offenders.

Marange workers do not have a union. Their employers have made it difficult for employees to form unions. Instead thew workers are represented by workers committed which are highly vulnerable during times of unrest.

Regarding the labour issues, the proposed alternative is to assist workers in all the diamond mining companies to form a strong labor union that will represent their interests. This diamond workers union will affiliate to Zimbabwe Congress of Trade Unions to give it cover from the umbrella labor body This move will also bring the local diamond workers union into contact with regional and international mine workers, a move that is useful for advocacy purposes
Do you consider this as a success?No
Why? Explain briefly.No stiff penalties have been enforced on the polluting companies. One of the companies reported on its website that the environmental laws in Zimbabwe are lax, adding that it is cheaper to pollute and pay fines than to prevent pollution. Due to the involvement of state security agents and senior politicians in diamond mining, companies that are polluting appear to be operating above the law.

The companies practice open cast mining, thereby destroying the environment, polluting the air and exposing workers to diseases. At DMC the workers allege that employees who are based at the sorting plant are subdued to huge amount of dust but the Arabic Management has up to now failed to provide protective masks and respirators.
