oa CSIR Science Scope - Reducing the human footprint : towards sustainability
The 'human footprint' is used as a metaphor for mankind's demands on the earth's ecosystems and natural resources. It is an expression of the amount of land a population needs to produce the resources it consumes and absorb its wastes. Although South Africa's footprint is only slightly higher than the global average, it is more than double that of Africa's average. Our current footprint exceeds our biological capacity by 3,5 million global hectares.
