1. People, food and density. 2. As a big city, naturally, people are always moving in and out. There are people who live here permanently (stock) and others come here for work or leisure (flow). There are also university students. In fact, each year hundreds of students arrive to pursue their studies, living there temporarily. Food enters the city mainly from outside. Then, people buy it in supermarkets or simply order it. Food represents an important flow, being temporarily retained (stock) in commercial surfaces. Regarding to density, Oporto (Portugal) is very dense. This is easily perceived around attractive points, such as shopping centers, near the beach and river, near the subway station, monuments, etc. Some of them are stocks limited in time, very dynamic, that depend on the weather or schedules. 3. Positive changes will focus on the place and local people needs. More affordable rents will retain local people in the city. To change food stocks and flows, we can create ecological gardens in the city where even locals could plant their own vegetables, turning the city more sustainable. Density changes with new attractions. We can’t predict them but we can design them to spread harmoniously throughout the city.
