Worked Solution & Example Answer:Robben Island is of historical relevance and is conserved as a Category 3 Marine Protected Area - NSC Marine Sciences - Question 5 - 2021 - Paper 1
Step 1
Whether the island is classified under the correct category (Category 3 MPAs are considered natural monuments mainly due to cultural reasons.)
Answer
Robben Island's classification as a Category 3 Marine Protected Area is justified because it embodies high cultural and historical significance. The presence of endemic species, particularly the endangered Cape Cormorants, emphasizes its ecological importance. Hence, retaining its protective status aligns with environmental conservation objectives.
Step 2
What potential conservation measures can be used to prevent overfishing of stocks
Answer
To prevent overfishing, several measures can be implemented:
- Legislation: Enforcing strict fishing quotas through regulations.
- Monitoring: Regular assessments of fish populations and habitats.
- Education: Raising public awareness about sustainable fishing practices.
- Replenishment Areas: Designating no-take zones to allow fish stocks to recover, further supporting ecosystem stability.
Step 3
The ecological significance of the kelp forests to the marine ecosystems around Robben Island
Answer
Kelp forests are vital to marine ecosystems as they provide habitat, shelter, and food to diverse marine life. They serve as breeding grounds for numerous invertebrates and filter feeders. The kelp also plays a critical role in wave action reduction, creating calmer conditions for other species to thrive, thereby enhancing biodiversity.
Step 4
The difference between nature-based tourism and ecotourism and how that relates to the island
Answer
Nature-based tourism emphasizes enjoyment of natural surroundings but often neglects environmental sustainability. Conversely, ecotourism focuses on responsible travel practices that enhance environmental and cultural conservation. At Robben Island, promoting ecotourism could ensure that tourism supports conservation efforts while preserving local ecosystems.
Step 5
Whether enough is being done to protect the coastal ecosystems around Cape Town
Answer
Despite various efforts, the protection of coastal ecosystems remains inadequate. Issues such as overfishing, pollution, and habitat degradation persist. Increased enforcement of protective regulations and the implementation of more conservation initiatives, such as marine protected areas and community engagement programs, are essential for ensuring ecological health.
