Impacts in Southern Africa• Direct physical disturbance
– Physical removal of benthic organisms, kelp cutting
– Deposition of tailings
– Habitat loss or alteration incl. sediment type
– Irreversible damage that can transform habitat
– Temperature changes
• Sediment plumes and pollution
• Benthic pelagic coupling impacts
• Underwater Noise
• Alien and Invasive species

Key considerations
Biodiversity significance
How important is the area in contributing towards biodiversity
goals?
Species of concern
Are threatened or sensitive species
associated with the area and to what
degree are they likely to be impacted?
Threatened and sensitive habitats
Does the area include threatened and
sensitive habitats?
Ecosystem services
What are the key services in the area and
to what extent will these be negatively
affected?

Fisheries 1. Fishing is an important ecosystem
service that should be maintained
2. South Africa has 18 fishery sectors
3. Many associations & groups, many overlapping rights

Progress to date and where Namibia is at now:
• Submission by the Minister of Fisheries and Marine Resources led
to a Cabinet Decision in 2013 to impose a Moratorium on industrial
minerals marine mining activities
• Cabinet directed that
o a Strategic Environmental Assessment (SEA) be conducted to assess
the cumulative impacts (specified to phosphates)
o an independent scoping study and a comprehensive Environmental
Impact Assessment is being carried out
• Following I&AP circulation of the draft report, final report will be
submitted to the proponent Ministry of Fisheries and Marine
Resources for decision and further action
