The global agriculture has a high environmental impact (30 percent of global emissions). This is mainly the case due to long supply chains. Currently, the average distance traveled for agricultural products is more than 2,400 km (Urban Farming in the City of tomorrow, 2018) . Using an Urban Farming approach, this distance can ideally be reduced to less than 10 km. This offers a new attractive option for a decarbonised food distribution system. In addition to this, securing urban food and resource supply is increasingly becoming a challenge, especially in heavily populated cities with limited access to surrounding agricultural areas. Thus, food produced within urban areas offers various opportunities for cities. There are different types of urban farms, e.g. differentiated by the location of the farm (such as rooftop, window, greenhouse, balcony, containor, inddor or vertical farming), differentiated by the method of farming (such as hydroponic, aeroponic or mistponic farming) or differed by the people cultivating the plants (such as community, instiutional, commercial or personal farms). The following information gives a general overview, but mainly focuses on indoor and vertical farming.
