  4. 4. Definition What does ―Bio‖ mean? BIO = What does ―DIVERSITY‖ mean? DIVERSITY = VARIETY 20/11/2013
  5. 5. Biodiversity  Biodiversity is the variety of life on earth and the essential interdependence of all living things (species).  The term was coined by Edward O. Wilson amongst others, as an ecological concept to include all the living organisms of a given system, from the monera to the trees, annelids to mammals. 20/11/2013
  6. 6. Components of Biodiversity Genetic Variety  Differences in inheritable characteristics that are present in a population Chihuahua 20/11/2013 Beagle Rottweilers
  7. 7. Species Variety  Species is a particular type of organism or population of organisms which share some characteristics and can interbred to produce a fertile offspring 20/11/2013
  8. 8. Ecosystem Variety  An ecosystem is made up of interacting populations and the abiotic factors that support them. 20/11/2013
  9. 9. Benefits of Biodiversity Food Security  Many species not now commonly used for food could be. 20/11/2013
  10. 10. Medicine  Every species that goes extinct represents one lost opportunity to find a cure for cancer, hepatitis & HIV/AIDS. Rosy periwinkle 20/11/2013
  11. 11. Economic Benefits  Affluent tourists pay good money to see wildlife, and protected ecosystems. 20/11/2013
  12. 12. Environmental & Ecological Benefits Protection from floods and droughts  Stable ecosystems with adequate trees help regulate the water cycle by acting as temporal sinks. 20/11/2013
  13. 13. Soil Fertility Sustenance  Micro-organism and macroorganism activities aerate soils.  Nutrient cycling by deep rooted trees Earthworm in soils 20/11/2013
  14. 14. Aesthetic Benefits  Biophilia; human love for and attachment to other living things; ―the connections that human beings subconsciously seek out with the rest of life‖: Keeping of pets Valuing real estate with landscape views Interest in escaping cities to go hiking, birding, fishing, hunting, backpacking, etc. 20/11/2013
  15. 15. Benefits of Biodiversity  Research (Motivation and generation of ideas) 20/11/2013
  16. 16. Factors Militating Against Biodiversity Population Growth  7 billion people who need to be fed. 20/11/2013
  17. 17. Overexploitation of Resources  Extraction of flora and fauna resources beyond sustainable thresholds Deforestation 20/11/2013
  18. 18. Global Warming and Climate Change  Emissions of ―greenhouse gases‖ are causing temperatures to warm worldwide, increasing the frequency of extreme weather events. Polar bear on melting ice 20/11/2013
  19. 19. Species Introduction  Accidental or intentional introduction of exotic species to new areas.  Most do not establish or expand, but some do—likely because they are ―released‖ from limitations imposed by their native predators, parasites, and competitors. 20/11/2013 Japanese Kudzu
  20. 20. Species Introduction 20/11/2013
  21. 21. Pollution  Air and water pollution; agricultural runoff, industrial chemicals. 20/11/2013
  22. 22. Pollution (cont.) Eutrophication  Eutrophication occurs when fertilizers, animal wastes, sewage, or other substances rich in nitrogen and phosphorus flow into waterways, causing extensive algae growth. 20/11/2013
  23. 23. Pollution (cont.) Acid Rains  Sulfur and nitrogen compounds react with water and other substances in the air to form sulfuric acid and nitric acid.  Acid precipitation removes calcium, potassium, and other nutrients from the soil, depriving plants of these nutrients.  It damages plant tissue and slows their growth. 20/11/2013
  24. 24. Pollution (cont.) Biological magnification  Biological magnification is the increasing concentration of toxic substances in organisms as trophic levels increase in a food chain or food web. 20/11/2013
  25. 25. Conservation  Conservation is an ethic of use, allocation and protection of valued resources.  Biodiversity Conservation implies the use, allocation and protection of the variety of flora and fauna resources in a manner that ensures the sustainability of these resources. 20/11/2013
  26. 26. Why Biodiversity Conservation? 1. To Ensure Food Security Ireland Potato famine 1845 20/11/2013
  27. 27. Why Biodiversity Conservation? 2. Prevents extinction of species  30 per cent of amphibians, 23 per cent of mammals and 12 per cent of birds are threatened (IUCN 2006). DODO BIRD 20/11/2013
  28. 28. Why Biodiversity Conservation? 3.To sustain ecosystem services 20/11/2013
  29. 29. Why Biodiversity Conservation? 4. Maintenance of cultural heritage. Parrot – Totem of Agona 20/11/2013
  30. 30. The Way Forward Policy and Legislation  Policy is a proposed or adopted course of action that guide decision to obtain rational outcomes.  Legislation proclamation of laws by a recognized institution. 20/11/2013
  31. 31. The Way Forward  Conventions, Protocols & Treaties Trade Record Analysis of Flora and Fauna in Commerce (TRAFFIC) Cartagena Protocol on Biosafety 20/11/2013
  32. 32. The Way Forward  Education 20/11/2013
  33. 33. The Way Forward Restoring Ecosystems  Bioremediation  The use of living organisms, such as prokaryotes, fungi, or plants, to detoxify or remove pollutants.  Technologies can be generally classified as in situ or ex situ.  Oleispira antarctica 20/11/2013
  34. 34. The Way Forward Biological Augmentation  Adding natural predators to a degraded ecosystem is called biological augmentation.  Ladybugs can be introduced into an ecosystem to control aphid populations. 20/11/2013
  35. 35. The Way Forward Controlled breeding programs 20/11/2013
  36. 36. The Way Forward Natural Resource Management  Sustainable Forest and Wildlife Mgt. 20/11/2013
  37. 37. The Way Forward Sustainable Aquaculture Raising of fishery resources in controlled environments. 20/11/2013

  40. 40. Did You Know?  According to UN Food and Agriculture Organization estimates, 100 crop species supply 90 percent of the world's food and bees pollinate more than 70% of these crops! 20/11/2013
  41. 41. Did You Know?  As estimated by the IUCN, 50 percent of all endangered species live in the rainforest. The planet’s largest rainforest –The Amazon – lost more than 17 percent of its forest cover in the last century due to human activity. 20/11/2013
