Smart roofs for a sustainable city- Managing climate change

Since roof areas of cities in India tend to be under designed and sterile zones what can be done on the roof to make it 'productive'? The list goes like this
- Harvest rainwater from the roof as a catchment
- Harvest the sun using cookers,water heaters and photovoltaics
- Grow food like rice and vegetables
- Treat greywater using plants
- Build an eco-san toilet to nourish the crop

It seems if you have 50 square metre per person in India you could do a tremendous job for water,food,energy and ecological security.

These are simple 90 litre barrels. The water at the inlet comes in from the top through a pipe and is allowed to drop down. It is again picked up at the tope of the barrel to lead it to the next one.
