I'd suggest you try it your self.
try growing stuff on a city balcony. assuming sun and water, it'll grow really well, due to the urban heat island.
However when you get pests, thats it, game over. you've got black fly, and they are never going away(I tried sprays, buying ladybirds, nematoads)
Why? because you only have one tiny portion of the ecosystem that is based on pests. Most pests are way down the food pyramid.
Now, I moved to an allotment, with a huge range of crops, which has a huge range of pest and predators. I had black fly for a week, and then the ladybirds came.
Why? because pests are seasonal, you need broad range of pests to keep the predators in any useful numbers.
