Regarding water at least, it's a lot easier, cheaper, and less energy-intensive to pump water from a waterways/well and spray it on crops than it is to use water processed and delivered through a municipal system. Plants don't need that's been fluoridated or otherwise heavily treated. Especially since fresh water in most dense urban areas is not very plentiful (with some exceptions), I would find it hard to believe that the decrease in water needs outweighs the lack of availability and cost.
