Transcript

  • 1. EFT 1023 BIODIVERSITY
  • 2. AGROBIODIVERSITY A. Introduction to agrobiodiversity B. Benefits of agrobiodiversity C. Loss of agrobiodiversity D. Best practices
  • 3. Presentation Title A. Introduction to Agrobiodiversity “All the component of biological diversity associated with food and agriculture, and all components of biological diversity that related to agricultural ecosystems: the variety & variability of animals, plants and microorganisms at the genetic, species and ecosystem levels, which are essential to sustain key functions of the agroecosystem, its structure and processes” Convention on Biological Diversity (CBD)
  • 4. Dimension of agrobiodiversity: 1.Genetic resources for food and agriculture 2.Components of biodiversity that support ecosystems functions/services which related with agriculture 3. Abiotic factors 4.Socio-economics
  • 5. Genetic resources: Food and agriculture encompasses of: → plants, animals & microorganism → cultivated/domesticated species → wild plants and animals
  • 6. Ecosystem services Components of biod (organisms) that support ecosystem services in agricultural systems: → Pollination → Water and nutrient cycles → Decomposers → Pest and diseases regulation
  • 7. Abiotic factors Non-living factor that affect agrobiodiversity: → climatic factor → chemical factor
  • 8. Socio-economic & cultural Socio-economic & cultural dimension included: → traditional & local knowledge of agrobiodiversity → cultural factors → tourism (ecotourism/agrotourism) with agricultural landscape
  • 9. B. Benefits of agrobiodiversity • Source of food and nutrition (human, livestock & cultivated plants) • Medicine and health value • Ecosystem services (pollination, food chain) • Genetic resources (plant/animal) • Knowledge (taxonomy) • Economic value • Socio-economic to support livelihood
  • 10. C. Loss of agrobiodiversity Habitat loss Deforestation OvergrazingUnsustainable farming Population boom Global warming
  • 11. C. Loss of agrobiodiversity Causes & Factors • Environmental pollution • Deforeststation • Overgrazing • Global warming • Climatic change • Overharvest (forest, fisheries) • Desertification • Ozone depletion • Nature disaster Impacts • Population decreasing • Soil nutrient deteriorate • Damage to DNA • Influencing animal & plant growth • Morphology • Biomass accumulation • Effect on reproduction (reduce reproductive succcess) • Disruption of food web
  • 12. D. Best Practices Enhance agrobiodiversity
  • 13. Good practices a. Organic farming b. Organic trade/product c. Integrated Pest Management IPM d. Seed Bank Systems (SBS) e. Practicing good farming management f. Species combination enhance productivity and yields g. Promote diversity of crops (temporal/spatial) h. Pollinators management i. Maintenance of wild patches of vegetations in farming j. Minimal soil disturbance k. Promote a healthy & diverse soil community l. Integrating livestock in crop production system m. Application of biological control (natural pest control strategies) n. Alternative policies for agriculture o. Research and education p. Market value strategies SUSTAINABLY
