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 is correctly classified as a Category 3 Marine Protected Area (MPA) due to its historical and cultural significance. This classification reflects its role not only as a breeding ground for endangered species like the Cape Cormorants but also its importance in preserving cultural history and memory associated with the site.
Step 2
What potential conservation measures can be used to prevent overfishing of fish stocks
Answer
To prevent overfishing, various conservation measures can be employed:
- Legislation: Implementing stricter fishing laws and regulations.
- Monitoring: Regular monitoring of fish populations to assess stock levels.
- Replenishment Areas: Establishing no-take zones where fishing is prohibited to allow fish stocks to recover.
- Research: Conducting scientific research to understand the ecosystem dynamics and implement adaptive management strategies.
Step 3
The ecological significance of the kelp forests to the marine ecosystems around Robben Island
Answer
Kelp forests provide vital ecological services. They serve as:
- Habitat: A habitat for numerous marine species including fish and invertebrates, enhancing biodiversity.
- Nutrient Cycling: Kelp contributes to nutrient cycling in the marine environment by absorbing carbon dioxide through photosynthesis.
- Erosion Prevention: Their structure helps prevent coastal erosion by breaking the force of incoming waves.
Step 4
The difference between nature-based tourism and ecotourism and how that relates to the island
Answer
Nature-based tourism focuses on the enjoyment of natural areas but often neglects environmental sustainability. Ecotourism, however, emphasizes responsible travel to natural areas, aiming to conserve the environment and improve the well-being of local communities. In the context of Robben Island, promoting ecotourism practices can contribute to conservation efforts while educating visitors on the island's environmental significance.
Step 5
Whether enough is being done to protect the coastal ecosystems around Cape Town
Answer
While there are several conservation efforts in place, much more is needed to adequately protect coastal ecosystems around Cape Town. Issues such as overfishing, pollution, and climate change continue to pose significant threats. It is vital to strengthen conservation laws, enhance community engagement in conservation efforts, and increase environmental awareness to ensure these ecosystems are preserved for future generations.
