PowerPoint Presentation:

Land resources Natural Resources that can obtained from the land is called land resources.

PowerPoint Presentation:

INTRODUCTION Almost every man-made product is composed of products of land resources. A natural resource may exist as a separate entity such as fresh water, and air, as well as a living organism such as a fish, or it may exist in an alternate form which must be processed to obtain the resource such as metal ores, oil, and most forms of energy .

PowerPoint Presentation:

Land is the most important resource existing. It is the major source of important energy resources like fossil fuels. Agriculture is not possible without land resources. Land also harbors all crucial minerals.

PowerPoint Presentation:

Mining Mining is the extraction of valuable minerals or other geological materials from the earth. Materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash. Any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory, is usually mined.

PowerPoint Presentation:

AGRICULTURE Agriculture output purely depends on land resource. Thus, lack of access to land increases incidence of poverty in rural areas. Quality of land has a direct bearing on the productivity of agriculture, which is not true for other activities.

PROTECTION In 1982 the UN developed the World Charter for Nature in which it recognised the need to protect nature from further depletion due to human activity . They state the measures needed to be taken at all societal levels, from international right down to individual, to protect all resources. They outline the need for sustainable use of natural resources and suggest that the protection of resources should be incorporated into the law system at state and international level. To look at the importance of protecting natural resources further. The World Ethic of Sustainability, developed by the IUCN, WWF and the UNEP in 1990 which set out eight values for sustainability, include the need to protect natural resources from depletion . Since these documents, there have been many measures taken to protect natural resources, some of these ways include Conservation biology and Habitat Conservation.

PowerPoint Presentation:

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 practice 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 organized by biologists Bruce Wilcox and Michael Soulé. Habitat conservation is a land management practice that seeks to conserve, protect and restore, habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction , fragmentation or reduction in range

Land Resources In India Land Resources in India enclose approximately 1.3 million sq miles and is a cape, protruding into the Indian Ocean, in between the Bay of Bengal on the east and Arabian Sea on the west. Indian land resources are segmented into varied relief features, 43% of land area is plain region; Indian mountain region constitutes 30% of the area, where as plateaus account for 27 % of the total surface area on the nation
