National park

National park


national park is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently (for example, see Martin Luther King, Jr. Memorial in the United States), an international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined National Parks as its category II type of protected areas. While ideas for this type of national park had been suggested previously, the United States established the first such one, Yellowstone National Park, in 1872. The largest national park in the world meeting the IUCN definition is the Northeast Greenland National Park, which was established in 1974. According to the IUCN, there were 6,555 national parks worldwide in 2006 that meet its criteria.

In 1969 the IUCN (International Union for the Conservation of Nature and Natural Resources) declared a national park to be a relatively large area with particular defining characteristics.[3] A national park was deemed to be a place

  • with one or several ecosystems not materially altered by human exploitation and occupation, where plant and animal species, geomorphological sites and habitats are of special scientific, educative and recreative interest or which contain a natural landscape of great beauty.
  • the highest competent authority of the country has taken steps to prevent or eliminate exploitation or occupation as soon as possible in the whole area and to effectively enforce the respect of ecological, geomorphological, or aesthetic features which have led to its establishment.
  • visitors are allowed to enter, under special conditions, for inspirational, educative, cultural, and recreative purposes.

In 1971 these criteria were further expanded upon leading to more clear and defined benchmarks to evaluate a national park. These include:

  • a minimum size of 1,000 hectares within zones in which protection of nature takes precedence
  • statutory legal protection
  • a budget and staff sufficient to provide sufficient effective protection
  • prohibition of exploitation of natural resources (including the development of dams) qualified by such activities as sport, fishing, the need for management, facilities, etc.

While national parks are generally understood to be administered by national governments (hence the name), in Australia national parks are run by state governments and predate the Federation of Australia.

Mining Engineering

Mining engineering is an engineering discipline that involves practice, theory, science, technology, and the application of extracting and processing minerals from a naturally occurring environment. Mining engineering also includes processing minerals for additional value.

Environmental Engineering

Environmental engineers are the technical professionals who identify and design solutions for    environmental problems. Environmental engineers provide safe drinking water, treat and properly dispose of wastes, maintain air quality, control water pollution, and remediate sites contaminated due to spills or improper disposal of hazardous substances. They monitor the quality of the air, water, and land. And, they develop new and improved means to protect the environment.
