Are we making progress?

The coastal land in South Africa has been classified as natural, degraded, urban, and agricultural.  Most urban land use occurs in the three largest coastal metropoles: Cape Town (25%), eThekwini (27%), and Nelson Mandela (12%).  Cape Town, eThekwini, and iLembe are the municipal areas that have been most transformed from their natural state.  Not surprisingly, the sparsely populated Namaqua region has the highest proportion of natural land cover (98%), followed by Cacadu (92%), Eden (76%), Amatole (75%), and Nelson Mandela (74%).
