Presentation Transcript

  1. Integrated Coastal Zone Management Unit 2: Coastal Vulnerability

  2. Introduction • Unit content • Identifying human impacts on the coast • Exploring coastal vulnerability • Relating human impacts to coastal vulnerability • Learning outcomes • Upon completion of this unit, students will be able to • Appreciate the range of human activities and their coastal impacts • Recognise the importance of magnitude and scale on coastal impacts • Understand the concept of coastal vulnerability • Understand how coastal activities affect coastal vulnerability

  3. Human activities & impacts

  4. Human activities & impacts

  5. Direct and indirect impacts Example: agriculture

  6. Direct and indirect impacts Agriculture Direct impacts: eutrophication, pollution, salinisation Indirect impacts: biodiversity loss, erosion, subsidence Urbanisation Direct impacts: eutrophication, pollution, habitat loss, turbidity, sediment movement Indirect impacts: biodiversity loss, erosion Climate change Direct impacts: sea level rise, temperature rise, flooding, erosion, acidification Indirect impacts: biodiversity loss, altered species abundance Conclusion: loss of biodiversity is indirectly associated with all human activities

  7. Coastal vulnerability

  8. Coastal sensitivity Sensitivity: probability of human impact affecting the environment (for example, biodiversity loss) What aspects of the following ecosystems make them more or less sensitive to human impacts? Coral reefs Seagrass meadows Mangroves

  9. Managing threats What are localised threats to coral reefs? Fishing Agriculture Forestry Building development Industrial activity Tourism

  10. Managing threats What are localised threats to coral reefs? What are appropriate management options? Fishing Agriculture Forestry Building development Industrial activity Tourism Increased regulation Increased enforcement Subsidising alternative activities Promoting environmental awareness

  11. Managing threats What are localised threats to coral reefs? What are appropriate management options? Fishing Agriculture Forestry Building development Industrial activity Tourism Increased regulation Increased enforcement Subsidising alternative activities Promoting environmental awareness Choice of management options = coastal management plan
