1/ Can cities grow a meaningful share of their own food? 🏙️
🌱 A study on Barcelona shows that using just 65 ha of rooftops (0.64% of the city's area), rooftop greenhouses could produce 5,878 t of tomatoes 🍅, 507 t of peppers 🫑and 78 t of lettuce every year.🥬

2/ The key insight isn't just growing food on rooftops, it's growing what people actually eat. 📝The study compares different production strategies and shows urban agriculture can improve food resilience, shorten supply chains and make better use of existing buildings.🏢
