This is a profitable idea.
I've seeen this before and liked the idea. It can't be denied that the population and the demand for food is both growing.
City mayors/officials can implement policies to support/incentivize new Green projects (aside from current Green prpjects), such as housing complexes with green roofs where homeowners can make communal gardens or they can lease it to farmers as a side income.
Don't know how would that work in the real world, but it's a beautiful idea to implement.
Indeed... although most green roof owners converts their rooftops into recreational garden in the likes of the rooftops in Linz, Austria , NYC, Norway, etc. Fkat owners in a building would normally get together to plan their new garden. I think the rooftops will not be sufficient for the farmers needs, they always have big scale farming and requires acres of land... the one thing good though is that flat owners could get together and make the building rooftop a n oasis for relaxation... Thanks for dropping -by to comment. Have a lovely Tuesday!
Yes, may need more research for efficiency and feasibility, but it's good idea. Green rooftops maybe great for recreational area and/or small urban gardens for now :)
