Part 7/12:
Local Self-Sufficiency (50x50): Aiming for half of the city’s nutritional needs to be produced locally via urban farming, vertical agriculture, aquaponics, and alternative proteins like lab-grown meat.
Global Food Resilience: Relying on diversified international import sources, strategic stockpiling, and strengthening cross-border food trade networks.
Teams critique each other's strategies, considering logistical, environmental, and geopolitical factors. The judges note that local solutions may reduce dependency but face land and technological limitations. Conversely, global diversification offers supply security but exposes the city to regional disruptions.
