Here’s a sketch of an idea running through my head for some days. A possible mechanism for growing vegetables (or other plants) underground. Will be trying it out next week and will post updates. Now, why would one do this?
The tree farming effort and the “underground farming,” both are ways of seeking “safe” and potentially uncontested public spaces to grow publicly accessible vegetables. Safe from vandals, unconscious destruction (like trampling, and we seldom have pavements here in India, so trampling is very likely to happen), animals (monkeys, cows, dogs) and traffic. The idea is that we will be able to find niches, which besides not getting in anyone’s way and being safe, might make an aesthetic impact in the environment in which they are placed.
Once these niches are identified and taken up, they could be marked in ways so that those seeking them (the homeless, street children, other urban farmers) can still do so without much difficulty.
