In Hong Kong, 80 per cent of food is imported from China and only 8 per cent is produced on local farmland, resulting in low self-sufficiency. Consequently, food supply, green spaces, and a clean air environment will be the main issues of our future. The story of how food can be grown in and on existing buildings, transforming their form and the entire streetscape, as well as the relationship between the inventions and characters actions is designed as a game – Guerrilla Planter – which allows to participate, to engage with, play with, and imagine about the possibilities of self-supporting farming and sustainable living.
