Natural resources

  1. 1. By Ayush Garg
  2. 2. What Are Resources?  Anything that can be used to satisfy a need is a resource. A resource is a source or supply from which benefit is produced.  For example: land, minerals, air etc.
  3. 3. Value Of A Resource  The purely economic value of a resource is controlled by supply and demand.  This is, however, a narrow perspective on resources.  There are many things that cannot be measured in money.  Natural resources like forests, mountains etc. are considered beautiful so they have aesthetic value.  Resources also have an ethical value as well, because it is widely recognized that it is our moral duty to protect and conserve them for the future generations.
  4. 4. Characteristics of resources  Resources have three main characteristics:  Utility  Quantity(often in terms of availability)  Consumption  And Potential for Depletion and Consumption
  6. 6. Biotic resources are those obtained from the biosphere. Examples-Forests and their products, animals, birds and their products, fish. Other marine organisms. Minerals such as coal and petroleum are sometimes included in this category.
  7. 7.  Abiotic resources comprise non-living things.  For examples include land, water, air and minerals such as gold, iron, copper, silver etc.
  8. 8.  Renewable resources are those that can be replenished or reproduced easily.  Sunlight, air, wind, etc., are continuously available and their quantity is not affected by human consumption.  Many renewable resources can be depleted by human use, but may also be replenished, thus maintaining a flow.  Like agricultural crops, take a short time for renewal  Others, like water, take a comparatively longer time.  while still others, like forests, take even longer.
  9. 9.  On the basis of the stage of development, natural resources may be called: Potential Resources  Potential resources are those that exist in a region and may be used in the future.  For example, mineral oil may exist in many parts of India having sedimentary rocks  But until the time it is actually drilled out and put into use, it remains a potential resource.
  10. 10.  Non-renewable resources are formed over very long geological periods.  Minerals and fossils are included in this category.  Since their rate of formation is extremely slow, they cannot be replenished once they are depleted.  Out of these, the metallic minerals can be re-used by recycling them, but coal and petroleum cannot be recycled.
  11. 11. Based on Distribution Ubiquitous Localized
  12. 12.  On the basis of distribution, natural resources can be classified into:  Ubiquitous resources- the resources that can be found everywhere.  For example- air, light, water etc.  Localized-are those that can be found only in certain parts of the world.  For example-copper and iron ore, thermal power plant etc.
  13. 13.  Human beings are also considered to be resources.  The term Human Resources can also be defined as the skills, energies, talents, abilities and knowledge.  That are used for the production of goods or the rendering of services.
  14. 14.  Sometimes, natural substances become resources only when their original form has been changed.  Iron ore was not a resource until people learnt to extract iron from it.  People use natural resources to make buildings, bridges, roads, machinery and vehicles.
  15. 15.  Which are known as HUMAN-MADE RESOURCES. Technology is also a human made resource.
  16. 16.  India's inland water resources comprising  rivers, canals, ponds and lakes and marine resources  comprising the east and west coasts of the Indian ocean and other gulfs and bays  provide employment to nearly 6 million people in the fisheries sector.  India is rich in certain energy resources which promise significant future potential - clean / renewable energy resources like solar, wind, bio-fuels
  17. 17.  India's major mineral resources include Coal (fourth-largest reserves in the world)  Iron ore, Manganese, Mica, Bauxite, Titanium ore, Cromite  Natural gas, Diamonds, Petroleum, Limestone and Thorium (world's largest along Kerala's shores).  India's oil reserves, found in Bombay High off the coast of Maharashtra, Gujarat, Rajasthan and in eastern Assam meet 25% of the country's demand.
  18. 18. Mica Ore Manganese Ore Thorium Bauxite Ore Limestone Titanium Ore
  19. 19.  India of proven oil reserves as of January 2007, which is the second-largest amount in the Asia-Pacific region behind China.  Most of India's crude oil reserves are located in the western coast (Mumbai High).  India had 38 trillion cubic feet of confirmed natural gas reserves as of January 2007.  2007.A huge mass of India’s natural gas production comes from the western offshore regions, particularly the Mumbai High complex.  The onshore fields in Assam, Andhra Pradesh, and Gujarat states are also major producers of natural gas.
