Urban farming, and the alternative use of city rooftops are increasingly popular. But what may be efficient use of space could also provoke conflict with classifications like the UNESCO world heritage status for the rooftops of Paris. UNESCO world heritage status is contingent on the protection of the historic appearance of the heritage site. Yet extensive rooftop farming in Paris could threaten exactly this historic appearance. Where do you think we should draw the line? Should a city like Paris sacrifice its obligation to protect its historic heritage in order to safeguard its future sustainability?
Recycling urban waste as possible use for rooftop vegetable garden
Innovative Commercial Urban Agriculture in the Paris metropolitan area
Good suggestion, I’ll add a sentence.
It may be beneficial to add a sentence explaining why a city like Paris would have to sacrifice its obligation to protect its historic heritage in order to safeguard its future sustainability or would maybe provoke conflict with UNESCO Heritage Sites, etc. This way, I think we would have a better understanding of your second question here.
