The biggest challenge in the Yellow Zone hub has not been Tiberium, but in fact humanitarian. While the local population is mistrustful of GDI, and of the new fortress being erected on the coast, it has not stopped or meaningfully slowed their approaches, with some few hundred accepting offers to move to blue zones, primarily in North America, Africa, and Europe. Others have begun congregating near the hub as it provides protection from local warlords. While not precisely safe, especially without the presence of its MARV fleet, (despite some being assembled from the overflow out of the Red Zone fleet being assembled this quarter) it is safer than most other regions, especially with the inflow of basic comforts, suchs as portable water filters, and solar tarps, along with prefabricated shelters. While before Tiberium the population clinging to the walls (and occasionally spilling onto the MARV tracks before being asked to move by GDI officers) would have been called a favela, but in all practicality, it also represents a significant improvement in living conditions.
The hub itself is placed on the coast, and will effectively cut off connection or uncontrolled migration from South America north, or south from mesoamerica. In coordination with the other fleets in the region, it will create opportunities for large sections of the yellow zone to be controlled and made generally safe for the population, despite the efforts of the Brotherhood of NOD.
