The project is called Landgrab City. It's located in downtown Shenzhen. It's by Joseph Grima, Jeffrey Johnson, and José Esparza. The small blackish section at the corner represents the city (Shenzhen), and the rest represents the area needed to feed this city. Shenzhen has a population of 10,000,000. If a social engineer hopes to meaningfully transform his/her society, then he/she must first strength its inhabitants sense of cognitive mapping. Without an adequate big picture, a mental sense of where things are and how each thing relates to other things and places, the citizen will be no better than an ant and the city will be just a hive of unrelated and unthinking individuals.


As for urban agriculture, Havana is the city of the future...
Havana, Cuba, is a world leader in urban agriculture. After the collapse of the Soviet Bloc, food production was decentralised from large mechanised state farms to urban cultivation systems. Today more than 50 per cent of Havana’s fresh produce is grown within the city limits, using organic compost and simple irrigation systems.
50 percent! The 16th century Dutch philosopher Spinoza once wrote that no one knows what the body can do. The same goes with the city: No one knows what it can do. As Havana was abandoned by communism, Detroit was abandoned by capitalism. What the inhabitants of each of these cities were left with was nothing but the city itself, and they had to discover what it can do.
