Accumulation of pressures that may cause the entry of non-native species into the South Atlantic Demarcation (EM SUD PRE Non-native Species)
Description
Cumulative pressure analysis was performed for 5 x 5 minute meshing. No distinction has been made between input vectors and vectors that facilitate dispersion. Therefore, all pressures for which spatial information is available and which may cause entry and dispersal of non-native species have been considered together, namely:
- Aquaculture facilities
- Ports of general interest (areas I and II)
- Other ports
- Monobuoys
- Roundabouts
- Oil platforms
- Approved locations for the discharge of dredged material from port areas
Given the difficulty in establishing zones of influence of the non-indigenous species (since their dispersal capacity depends on each species), only the cells containing or intersecting any of the layers used have been selected for the generation of the index. Each pressure has been assigned a value of 1, doubling the ports of general interest and quadrupling those with a bulk cargo of more than 6 million tons. He's finally joined in. Cells are classified according to the following criteria:
Very High: 4 to 7 / High: 3 / Medium: 2 / Low: 1 / Very Low: 0
