Debmarine Namibia conducts diamond mining in the Atlantic Ocean, within the Benguela upwelling system, a biologically productive system that supports a vast array of different species; therefore, any effects on the ecosystem must be carefully considered.

Environmental responsibility is at the core of our commitment to the future of Namibia. We recognise environmental resources as a national asset and endeavour to understand and mitigate environmental impacts at every stage in the mining lifecycle.

Debmarine Namibia’s Environmental Management system has been certified to the international ISO14001 standard since 2002, which ensures that operations meet legal compliance requirements and allows the company to strive for continual improvement in environmental management.

The rehabilitation of mined marine environments occurs naturally and recolonization/recovery takes place once mining operations have ceased in a particular area. Debmarine Namibia’s environmental research focuses on obtaining greater knowledge of the natural variability of the environment, understanding the consequences of marine mining and monitoring changes over time. Ongoing monitoring surveys are conducted by independent scientists and the results which are published in an annual report are peer-reviewed by internationally recognised marine scientists.  Partnerships with academic and research institutions in southern Africa ensure that the scientific integrity and the continuous innovation of our research is maintained.
