Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

The most common surface mining methods such as strip mining, open pit mining, opencast mining and quarrying start from the earth’s surface and keep exposure to the surface during the extraction period. Disruption of the surface significantly affects the soil, fauna, flora and surface water, thereby influencing all types of land use.

Algeria Algeria Economy: Algeria’s economy is dominated by its export trade in petroleum and natural gas, commodities that, despite fluctuations in world prices, annually contribute roughly one-third of the country’s gross domestic product (GDP). Until 1962 the economy was based largely on agriculture and complemented France’s economy.
