L 1 geo class x resource & development
- 2. WHAT IS A RESOURCE??? Everything available in our environment and which satisfy our needs It should be 1.) Technologically accessible 2.) Culturally acceptable 3.) Economically feasible
- 3. CLASSIFICATION OF RESOURCES ORIGIN EXHAUSTIBILITY OWNERSHIP DEVELOPMENT Classification of resources on the basis of
- 4. RESOURCES-ORIGIN • Obtained from Biosphere and have Life • Examples- Flora, Fauna, Fisheries, Livestock, Human Beings BIOTIC • All the things which are Composed of Non Living Things • Examples- Rocks, Metals ABIOTIC
- 5. RESOURCES-EXHAUSTIBILITY Resources on the basis of Exhaustibility Renewable These resources can be renewed/recycled. For Example Solar and Water Energy, Forests etc. Further Divided into Continuous- Water and Wind Flow-Natural Vegetation and Wildlife Non Renewable These resources cannot be renewed as they take million years to form. For Example Minerals, Fossil Fuels.
- 6. RESOURCES- OWNERSHIP INDIVIDUAL • The resources which are owned privately by individuals. • Example- Mobiles, Land. COMMUNITY • The which resources are accessible to all members of the society. • Example- Public Parks, Playgrounds. NATIONAL • The resources which belongs to the government. • Technically all resources belong to the nation. • Example- Roads, Oceanic area up to 19.2km. INTERNATIONAL • The resources belonging to international institutions. • Example- Oceanic resources beyond 200 nautical miles of the EEZ.(Exclusive Economic Zone)
- 7. RESOURCES-STATUS OF DEVELOPMENT POTENTIAL •Resources which are found in a region, but not have been utilized. •Like Rajasthan and Gujarat have potential of solar and wind energy but not been used for some reasons. DEVELOPED •Resources which are surveyed and their quality and quantity is determined for utilization •The development of resources depends on technology and level of their feasibility. •Coal, Petroleum STOCK •The resources which have potential to satisfy human needs but there is no technology to access these are included among Stock. •Like Water is a compound of Hydrogen and Oxygen which can be used as rich source of energy but there is technology to use it. RESERVES •They are subset of stock which can be use with existing technology but are conserved for the future generations. •Like river water is used to a limited consent for generating electricity so that it can be used in future.
- 8. DEVELOPMENT OF RESOURCES Development of Resources Essential for future as resources are limited in supply Exploitation Unequal Distribution Ecological Problem Scarcity of resources Depletion of resources
- 9. Rio de Janeiro Earth Summit,1992 • More than 100 heads of states met in Rio de Janeiro in Brazil, for the first International Earth Summit. • The Summit was convened for addressing urgent problems of environmental protection and socioeconomic development at the global level. Agenda 21 • It is the declaration signed by world leaders in 1992 at the United Nations Conference on Environment and Development (UNCED) • It aims at achieving global sustainable development.
- 10. LAND DEGRADATION DEFORESTATION INDUSTRIALWASTE OVERUSEOF FERTILIZERS QUARRYING OVERDRAZING MINING
- 12. RESOURCE PLANNING IDENDIFYING INVENTORY OF RESOURCES ECONOMIC AND TECNOLOGICAL EVOLUTION MATCHING RESOURCE DEVELOPMENT PLAN Resource Planning is widely accepted strategy for judicious use of resources. It has importance in a country like India which has enormous diversity in resources HOW IS RESOURCE PLANNING DONE???
- 13. SOIL AS A RESOURCE Most important natural resource. Medium of plant growth and supports different types of living organism on the earth. Takes million of years to form soil up to a few cm in length.
- 14. FACTORS AFFECTING FORMATION OF SOIL Parent Rock Climate Vegetation Wind Activity of Decomposition Glaciers Organic and Inorganic Materials Temperature
- 15. CLASSIFICATION OF SOIL Colour Thickness Chemical and Physical Properties Texture-Age Classification on the basis of :- ALLUVIAL BLACK RED LATTERITE ARID FOREST
- 16. ALLUVIALSOIL Very Fertile Formed by the deposit [Sand and Silt] brought by the rivers Found in Northern Plains, Coastal Plains, Deltas of Rivers Rice, Wheat, Cotton, Oil Seed Rich in Potash and Lime Deficiency in Nitrogen
- 17. BLACK SOIL Black in Colour Known as Regur Soil, Cotton Soil, Lava Soil Made up of lava flow [Breaking down of igneous rocks] Found in Maharashtra, M.P, Chhattisgarh, Godavari and Krishna Valleys Good Capacity to hold moisture Rich in Calcium Carbonate, Potash, Lime Deficiency in Phosphoric Content Crack occurs when dry Sticky when wet
- 18. RED AND YELLOW SOIL Found in Eastern and Southern part of Deccan Plateau Formed by the denudation of Igneous and Metamorphic Rocks Rice, Pulse, Sugar Cane Rich in Iron Deficiency in Nitrogen, Humus, Lime
- 19. LATTERITE SOIL Acidic Porous Leaching by Heavy Rainfall Found in Western Ghats, Shillong Coffee, Rubber, Cashew Rich in Iron Deficiency in Lime, Potash
- 20. ARID SOIL Formed by Weathering of Rocks Rich in Salt Deficiency in Humus Dates, Melon, Bajra Rajasthan, Punjab, Gujrat
- 21. FOREST SOIL Found in Rainforest and Hilly areas Acidic in Nature Deficiency in Humus
- 22. SOIL EROSION The denudation of the soil cover and subsequent washing down is called SOIL EROSION. • 1.) Human- Deforestation, Over Grazing etc. • 2.) Natural- Wind, Glacier etc Due to Human and Natural Factors The processes of Soil Formation and Erosion go on simultaneously and generally there is a balance b/w the two. • 1.) Gully Erosion • 2.) Sheet Erosion Types :-
- 23. Contour Ploughing – Ploughing around the contour lines to decelerate the flow of water down the slopes Terrace Farming – Cutting out the slopes and making terraces Strip Cropping – Strips of grass are left to grow b/w the crops. It breaks up the force of wind. Planting Shelter Belts – Planting lines of trees to create shelter.
