Sorry, my simplistic mind is only thinking this right now:

I've been tinkering with the idea of improving the agriculture situation in India. Though my idea was from a production side (large-scale hydroponics to lower cost via economies of scale and reduced transport cost). It didn't seem as feasible in the near future, but I love your idea! I'd be happy to talk with you as I'm curious about a few things and even see how I can help out!

Yes, a lot more needs to be done for this sector. But as you observed, a part of it does require a lot of input, in terms of capital and time.
