1a) Solid waste, people (commuters), and water. 2a) Solid waste is a flow, it's the end result of food and other stocks that are delivered into the city via flow channels. Food items are transported into the city, stored in markets and homes and then leave in the form of solid waste (garbage). b) People, specifically commuters are flows, they flow to and from the city on a daily basis and different channels of this flow can be large or small depending on the influx of commuters. For instance, in Melbourne the eastern suburbs make up the bulk of commuter transit, and as a result represent a large flow of commuters compared to the northern or western suburbs. c) Water is both a stock and flow. Water is transported to the city, through the Yarra river, and Melbourne water and Victoria Water. These two organizations store & treat the water for the city. Also, lakes, ponds, reservoirs and other sources of water represent non-potable stocks of water, that can be used for other means. Water is then used and flows back to these water organizations or leaves via water channels to the ocean and river. Imagine and shortly describe how these stocks and flows could change in the future for the benefit of your area. 3a) Solid waste could be dramatically changed, whereby less packaging, and different waste management practices are implemented to cut down on solid waste. Organics could be composted and turned into stocks of nutrients for use within the city and home. Other solid waste could be more efficiently recycled, lessening the strain on solid waste collection and disposal, whilst also prolonging the life of solid waste disposal sites by removing non decomposing items. b) Melbourne is currently working to improve it's transport system. Already one of the best in the world, Melbourne is investing in more green energy transport solutions, making transport, by car, train and other means more efficient (changing track crossings to prevent traffic along train lines), and connecting districts with public transport to limit car use. c) Water could flow from within the city, where water is captured for non potable use by roof and street water collection points.
