There is clearly an interest for public powers to be interested in city farming, regarding the percentage of people living in cities in the future, who will need to be fed.
nevertheless, not all cities are monsters like Paris, where real estate prices are so high that this is at the heart of public concerns.
In this context, is there really an interest for public power to drive public investment in City farming towards cities like Paris or New York?
I think that to some extent every city has its comparative advantage, or its potential. City farming has a lot of potential in areas less polluted and less overcrowded.
It would not be optimum to try to make Reims (one hour from Paris) the new capital of fashion. I don’t think this is a collective optimal choice of public investment to try to develop urban farming on Paris rooftops in a polluted and overcrowded environment. Shouldn’t we try to develop this kind of activities in (often deserted) periurban areas suffering from unemployment and lack of public interest?
But what would be the problem if Paris was really dependent to a city nearby specialized in agriculture? I mean isn’t it the basis of economic specilization? I mean overspecilization is bad for independance, clearly. But here, how can we expect a city like Paris, far from being independent regarding food since the 19th century, to develop agriculture? It seems to me that it is not the best allocation of public investment right now, in a context of crisis.
I definitely see your point, however, as far as I understood, the most important criteria in developing city farming in cities like Paris is related to the fact that because of its dense population an alternative must be found to be less dependent on external suppliers of vegetables (which is very risky especially in the context of a crisis). Cities like Paris or New York are probably among the ones that need the most city farming and this is the reason why this issue is so important for public powers.
The question could therefore reflect another aspect such as how could public policies related to city farming in large cities have an effect on the social dimension as well (e.g. activities in city farming that could also employ people that were not able to find a job), because big cities as well have an unemployment problem.
Because we have seen investment in city farming in large cities, perhaps it would be beneficial to ask what the benefits of having public investment in city farming in these cities such as Paris and New York are? Or rather, what would be the benefits (if any) in investing in city farming in periurban areas suffering from unemployment?
