Worked Solution & Example Answer:Robben Island is of historical relevance and is considered 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, designated as a Category 3 Marine Protected Area, holds both ecological and cultural significance. It is an important nesting ground for seabirds, particularly the endangered Cape Cormorant. The classification is appropriate as it reflects both its historical relevance and ecological value. The focus on conservation must balance cultural heritage with environmental protection.
Step 2
What potential conservation measures can be used to prevent overfishing of fish stocks
Answer
To prevent overfishing around Robben Island, several measures can be implemented:
- Legislation: Enforce strict laws regulating fishing quotas.
- Monitoring: Regularly monitor fish populations and fishing activities to ensure compliance.
- Education: Raise awareness among local fishers on sustainable practices.
- Replenishment Areas/No-take zones: Establish areas where fishing is prohibited to allow fish stocks to recover.
- Research: Conduct studies on fish populations to inform management decisions.
- Community Involvement: Engage local communities in the conservation efforts.
Step 3
The ecological significance of the kelp forests to the marine ecosystems around Robben Island
Answer
Kelp forests are crucial for supporting marine biodiversity around Robben Island. They provide habitat for various marine organisms, including fish and invertebrates. Kelp acts as a nursery for juvenile fish species, offers shelter from predators, and contributes to nutrient cycling in the ecosystem. These forests also mitigate coastal erosion and enhance water quality by stabilizing sediments.
Step 4
The difference between nature-based tourism and ecotourism and how that relates to the island
Answer
Nature-based tourism refers to any tourism that allows visitors to enjoy natural areas, but often lacks environmental considerations. In contrast, ecotourism emphasizes responsible travel to natural areas, fostering conservation and benefiting local communities. Robben Island can leverage ecotourism by educating visitors on its natural history and conservation efforts, ensuring that tourism contributes positively to ecosystem sustainability.
Step 5
Whether enough is being done to protect the coastal ecosystems around Cape Town.
Answer
While initiatives like the SANCCOB actions for Cape Cormorants show commitment to conservation, broader measures are necessary. Challenges like overfishing, pollution, and habitat destruction persist. Efforts must include stricter enforcement of marine protected areas, community education on sustainable practices, and ongoing research to assess ecosystem health. Therefore, while progress is being made, more comprehensive actions are essential for adequate protection.
