Tab 1: Test zone closures
Allows for the exploration of trade-offs from user-defined zone closures. Explore % of fisheries revenue protected and % whale risk avoided under different management scenarios. To test a management scenario, select which zone/s and time-period to close, how much fisheries effort to displace, and then click Calculate Tradeoffs. For the selected inputs, returns:
- Tradeoffs: the % of total revenue protected and whale risk avoided, absolute values for revenue protected and whale risk avoided.
- Monthly values within closed zones for revenue and whale risk.
Tab 2: Find optimal zone/s to close
Allows the user to find the best zones to close to maximize trade-offs. Find the optimal zones to close to one of three possible objectives: 1. By closest to optimal (result will be as close to 100% of revenue protected and 100% of whale risk avoided as possible); 2. By minimum revenue protected (result maximize avoided whale risk while protecting at minimum the user-defined revenue); 3. By minimum whale risk avoided (result will maximize protected revenue while avoiding at minimum the user-defined whale risk). For the selected inputs, returns:
- Tradeoffs: the % of total revenue protected and whale risk avoided, absolute values for revenue protected and whale risk avoided.
- Equally well performing scenarios that protect the same % of total revenue and avoid the same % of whale risk avoided.
Tab 3: View maps
View the distributions of fisheries revenue ($), blue and humpback whales (normalized between 0-1), and entanglement risk (a function of fishing vessel and whale distribution) for a user-defined month.
