With the rapid­ly grow­ing cities and glob­al­iza­tion, the local food pro­duc­tion has been increas­ing­ly reduced in favor of indus­tri­al­ly and / or glob­al­ly pro­duced food that is sold through retail chains. In recent years, how­ev­er, there has been a grow­ing inter­est in self-pro­duc­tion in the city.
Urban agri­cul­ture brings many advan­tages — of a social and inte­gra­tive nature, and at least as many pos­i­tive effects in terms of cli­mate pro­tec­tion and adap­ta­tion to cli­mate change.
How­ev­er, in order to be able to become a part of sus­tain­able nutri­tion for the urban pop­u­la­tion, the urban agri­cul­ture sys­tem must be rethought and mod­ern­ized. The areas pos­si­ble for cul­ti­va­tion and oper­a­tion such as roofs and walls of build­ings, open spaces in a city must be ascer­tained and sys­tem­at­i­cal­ly ana­lyzed for their poten­tial in struc­tur­al, tech­ni­cal, legal and prac­ti­cal terms.
Oper­at­ing mod­els — from vol­un­tary work to employ­ment mod­els must be sur­veyed and test­ed. Last but not least, it makes sense to har­mo­nize the agri­cul­tur­al activ­i­ties with the goals of the city in regard to cli­mate change adap­ta­tion and pro­tec­tion, i.e. to pro­mote urban agri­cul­ture where cool­ing, rain­wa­ter man­age­ment, etc. appear par­tic­u­lar­ly nec­es­sary. And to stim­u­late the pro­mo­tion of busi­ness mod­els there, for exam­ple in the form of pub­lic-pri­vate part­ner­ship concepts.
