Reclaiming mined-out areas Rehabilitating mines Restoring abandoned mine sites
Standard mine rehabilitation procedures include: landscaping; management of topsoil; revegetation; managing waste dumps, acid, alkaline and saline sites, heavy metals and toxic chemicals; removal of access roads and constructions.
In the last 200 years vast mining operations have been initiated to provide fuel and materials to the industrial revolution. Large open pits, waste dumps, stripped pasture land, and eroded hillsides, and swamps have resulted from these operations. Conservation movements, particularly in the last 30 years, have promoted restoration of these areas into graded slopes, seeded meadows, planted forests and dunes, and fishing ponds. In addition, some abandoned urban land has been converted into gardens, parks and sports areas.
In South Australia, mining operators are required under the Mining Act to pay a royalty (currently 10 cents per tonne) on all materials produced. The resulting Extractive Areas Rehabilitation Fund is used to finance approved rehabilitation projects. Often this is done with the assistance of horticultural advisers and rehabilitation consultants.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
