Forest Resources

  1. 1. FOREST RESOURCES <br />By <br />Ashish M Padaruth 0803012054<br />AbhishekSrivastava 08030121049<br />AmritanshuPathack 08030121050<br />
  2. 2.
  3. 3. Introduction<br />
  4. 4. Forests cover a third of our land on the planet earth <br />They provide raw materials, maintain<br /> biodiversity, protect land and water resources, and play a role in climate change mitigation<br />Forests are heavily exploited<br />
  5. 5. they can be damaged by fire, agricultural and urban expansion, and other disturbances<br />
  6. 6. Ten countries with largest forest areas (million ha)<br />
  7. 7. How much forest is there on the planet and at what rate is it disappearing?<br />
  8. 8. 30% of the global total land area is covered by forests<br />Forest area decreased worldwide by 0.22% per year in the period 1990-2000 and 0.18% per year between 2000 and 2005.<br />Primary forests account for over a third of global forest area<br />
  9. 9. Forest plantations are increasing but make up less than 5% of overall forest area<br />
  10. 10. Forest characteristics (%)<br />
  11. 11. How can forests affect climate change?<br />
  12. 12. by affecting the amount of carbon dioxide<br />carbon is removed from the atmosphere and absorbed in wood, leaves and soil<br />Forests are known as ‘ carbon sinks ‘<br />forest ecosystems store more carbon than the entire atmosphere<br />
  13. 13. Growing stock is a measure of the volume of stem wood in a given area of forest or wooded land<br />Carbon stock refers to the amount of carbon stored in the world’s forest ecosystem<br />
  14. 14. Total Carbon Stock (C) in forests by region<br />
  15. 15. What is the biological diversity of the world’sforests?<br />
  16. 16.
  17. 17. Biological diversity allows forest ecosystems to adapt continuously to changing conditions and to maintain their potential for meeting human needs<br /> The amount of primary forest provides a basic indication of biodiversity<br />Protected areas of forest are important to conserve biological diversity <br />
  18. 18. The number of native tree species found in different countries varies greatly<br />Rare tree species and those with high economic value are often in danger of becoming locally extinct<br />
  19. 19. Ten countries with the largest area of primary forest (%)<br />
  20. 20. Number of native forest tree species<br />
  21. 21. How healthy are the world’s forests?<br />
  22. 22. Forests can be damaged by disturbances such as fires, airborne pollution, storms, invasive species, pests, diseases, and insects<br />About 1% of forests (an area roughly the size of New Zealand) are consumed by fire each year<br />Problems caused by insects and diseases have increased in recent years<br />
  23. 23. Other forest disturbances include climatic factors such as wind, snow, ice, floods, tropical storms and drought, or impacts of animals<br />
  24. 24. What products are extracted from forests?<br />
  25. 25. Forests provide a wide range of products, not only timber and fuel wood, but also products such as food (berries, mushrooms ,etc.) and fodder<br />One third of the world’s forests are used primarily for production of wood<br />Growing stock is the amount of stemwood in a given area<br />
  26. 26. Volume of timber and fuel wood harvested has remained constant<br />Non-wood products provided by forests include food, fodder, and medicinal plants<br />
  27. 27. Five countries with greatest total growing stock (%)<br />
  28. 28. Ten countries with largest area of productive forest plantations (%)<br />
  29. 29. What are the protective effects of forests?<br />
  30. 30. conservation of ecosystems <br />in maintaining clean water<br />in preventing or reducing the severity of floods, avalanches, erosion and drought<br />An increasing area of the world’s forests is designated primarily for soil and water conservation<br />
  31. 31. Recognizing the important protective role of forests, many countries have planted trees for this purpose<br />
  32. 32. Designated functions of forests globally (%)<br />
  33. 33. What are the economic and social benefits of forests?<br />
  34. 34. Forests provide a wide range of economic and social benefits<br />The total value of harvested timber and fuelwood was about US$64 billion<br />The total global reported value of non-wood forest products was US$4.7 billion<br />
  35. 35. 10 million people are employed in forestry<br />Most of the world’s forests are publicly owned (84%), but private ownership is increasing<br />Use of forests for recreation and education is increasing<br />
  36. 36. Are forests managed in a sustainable way?<br />
  37. 37. There are many good signs and positive trends, but also many negative trends<br />At the global level, there has been a decrease in the area of forest<br />In Africa, overall, there was limited progress<br />In Asia, progress has been mixed<br />
  38. 38. In Europe, the status of forest has mainly been stable<br />Forest management has progressed in North and Central America as a whole<br />Progress in South America was mixed<br />Within world regions there are local differences<br />
  39. 39. Ownership of forests by subregion<br />
  40. 40. And what about tribal people?<br />
  41. 41. Conclusions<br />
  42. 42. Deforestation continues at an alarmingly high rate, but that the net loss of forest area is slowing down<br />If managed sustainably, forests also contribute significantly to local and national economies<br />Overall, progress towards sustainable forest management has been mixed<br />
  43. 43. The world’s forests<br />
  44. 44. Any Questions?<br />
  45. 45. Thank You<br />The End<br />
