"Given that cereals alone occupy much more land than all urban areas combined, it is clear that urban agriculture cannot literally feed the world," said Martellozzo, who was at 91社区 in Canada when he carried out this research. "However, urban agriculture could help hundreds of thousands of people increase their intake of vegetables."
