Step 1
Define the concept of a biosphere reserve.
Answer
A biosphere reserve is an area designated for the conservation of biological diversity and cultural heritage. It is designed to promote sustainable use of natural resources while safeguarding ecosystems. Biosphere reserves integrate ecological knowledge with cultural understanding, allowing for conservation efforts that involve local communities in the management and use of environmental resources.
Step 2
Explain how you intend to estimate the current fish stock along the West Coast using the Catch per Unit Effort method. In your answer, also state which decision variables need to be recorded in this process.
Answer
To estimate the current fish stock, I will utilize the Catch per Unit Effort (CPUE) method. This involves collecting data from fishers about the number of fish caught per unit of effort, such as hours fished or net size employed. Key decision variables to record include:
- Number of fish caught
- Fishing time (in hours)
- Type of gear used (e.g., nets, lines)
- Location of fishing By analyzing these variables, we can assess the health of the fish population and identify trends over time.
Step 3
Explain how the lagoon could potentially be suitable as an area for recreational fishing as well as ecotourism.
Answer
The lagoon can serve as a prime location for recreational fishing due to its rich biodiversity and relatively shallow waters, providing an ideal habitat for various fish species. Furthermore, its scenic beauty can attract tourists, fostering ecotourism opportunities. Activities such as guided fishing tours, wildlife watching, and educational programs about the lagoon's ecosystems can generate revenue while promoting conservation efforts.
Step 4
Discuss the principles and guidelines of The International Ecotourism Society (TIES) that would need to be followed if ecotourism is to be encouraged in the area.
Answer
The International Ecotourism Society (TIES) emphasizes several principles for sustainable ecotourism:
- Minimizing negative impacts on the environment and local culture.
- Building awareness and respect among tourists and the local community.
- Providing positive experiences for both visitors and hosts.
- Generating financial benefits for local economies. By adhering to these guidelines, we can ensure that ecotourism in the area contributes to conservation and the well-being of the community.
Step 5
Elaborate on both the possible reasons why some members of the community may oppose the establishment of a reserve, while other members might be in favour of the reserve.
Answer
Opposition to the establishment of a biosphere reserve may stem from concerns about limitations on fishing activities, which could threaten local livelihoods. Fishers may fear loss of access to traditional fishing grounds and potential restrictions on their practices. Conversely, support for the reserve may arise from community members who recognize the potential for enhanced tourism, job creation, and improved environmental conditions. Awareness of the ecological benefits and long-term economic incentives associated with the reserve can shift sentiments in favor of conservation efforts.
