gas to the world.
"Can't we think in that direction," he posed.
In a lighter vein, Modi also spoke about how difficult it would be to ensure that the country returns to high growth path.
India's economic growth remained below the 5 per cent mark for the second year in a row at 4.7 per cent in 2013-14.
"...but we have the backing of the people and we will bring back the growth at higher trajectory," he said.
He said, in infrastructure, the focus needs to shift from highways to "i-ways", and optical fibre networks.
"Cities in the past were built on river-banks. They are now built along highways. But in future, they will be built based on availability of optical-fibre networks and next-generation infrastructure," he said.
Modi said the "input of intellectual think tanks" should be substantially enhanced for better policy frameworks.
While talking about agriculture sector, he said no work has been done in the last 50-60 years to increase production of pulses.
"How we can increase per hectare pulses production?...the big challenge is that how to increase protein content in our pulses," Modi said, adding, "Farmers are dying. About 30 per cent of our produce get wasted due to lack of proper warehouses. We need to decentralise the warehouse concept."
On skill development, the Prime Minister said India has the capability to prove skilled manpower not only to India but to the world also.
