Most important stocks and flows: Food, water, people, density, land, capital, information and waste. Food used to be grown around where people stayed but as new things came up the area of staying close to the food resource was left behind and importing food products from far and wide started happening. People started moving to cities, and in came the role of capital and information. Stocks and flows of capital and information formed an important part of urban development. Capital has a major impact on cities than material stocks and flows. Location and the spatial arrangement of a city strongly affects the capital. With the change in capital due to location land comes as a stock and flow. At first it appears to be stable with little flow. But over time it either increases with the buildable area (horizontally) or grows high up (vertically). With growth of land, there is fluctuating stock and flow of people and food. With people and food comes a waste fluctuation. Waste can be a stock as well as a flow. If reused it can be termed as a flow but when kept stagnant it will be stock. The city of Mumbai is a good example of the important stock and flow. Mumbai is the economic capital of India. Day by day more and more people are immigrating to Mumbai in search of jobs and living spaces. This creates a flow in the existing stock of land, capital, information, food, waste and density in the city of Mumbai. P.S.: Image from Wikipedia.
