Natural Resources


Natural Resources


Natural resources is a type of resources in the earth which are economically referred to as land or raw materials occur naturally within environment that exist relatively undisturbed by mankind, in a natural form. A natural resource is often characterized by amounts of biodiversity existent in various ecosystems.

The examples of natural resources are agronomy, air, wind, atmosphere, plants, animals, soils, water, oceans, lakes and rivers.

Natural resource management
Natural resource management is a discipline in the management of natural resources such as land, water, soil, plants and animals, with a particular focus on how management affects the quality of life for both present and future generations. Natural resource management is interrelated with the concept of sustainable development, a principle which forms a basis for land management and environmental governance throughout the world.

In contrast to the policy emphases of Urban planning and the broader concept of Environment management,
Natural resource management specifically focuses on a scientific and technical understanding of resources and ecology and the life-supporting capacity of those resources.

Natural resource depletion
In recent years, the depletion of natural resources and attempts to move to sustainable development have been a major focus of development agencies. This is of particular concern in rainforest regions, which hold most of the Earth's natural biodiversity-irreplaceable genetic natural capital. Conservation of natural resources is the major focus of natural capitalism, environmentalism, the ecology movement, and green politics. Some view this depletion as a major source of social unrest and conflicts in developing nations.

Mining, petroleum extraction, fishing, hunting, and forestry are generally considered natural-resource industries. Agriculture is considered a man-made resource. Theodore Roosevelt, a well-known conservationist and former United States president, was opposed to unregulated natural extraction. The term is defined by the United States Geological Survey as "The Nation's natural resources include its minerals, energy, land, water, and biota."

Natural resource protection
Conservation biology is the scientific study of the nature and status of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction. It is an interdisciplinary subject drawing on sciences, economics, and the practise of natural resource management. The term conservation biology was introduced as the title of a conference held University of California at San Diego in La Jolla, California in 1978 organised by biologist Bruce Wilcox and Michael Soule.

Habitat conservation is a land management practice that seeks to conserve, protect and restore, shelter areas for wild flora and fauna, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterised in terms of any one ideology.
