This report addresses the issue of sustainable development in an economy dependent on mineral resources, a non-renewable resource. Mineral wealth can provide countries with a tremendous opportunity for economic development by providing the funding for investment and growth. Mining is a critical sector of the Namibian economy and mineral assets form a major source of national wealth. But the national accounts give a distorted picture of economic health because they record the contribution of mining to gross domestic product but not the simultaneous depletion of mineral wealth. Environmental and natural resource accounts overcome this limitation, providing accounts for the value of mineral reserves and the cost of depletion.
