Nepal, one of the world's poorest countries, is struggling to cope with the worst earthquake to hit the Himalayan nation in 80 years. The magnitude 7.9 earthquake struck some 80km northwest of the capital Kathmandu and has affected eight million people, just under one-third of the population with upwards of 5,000 people killed.

So what will it take to rebuild Nepal's shattered economy? What lessons can be learned? And who will step up to help one of the world's poorest nations?

Kenichi Yokoyama, the Nepal country director for the Asian Development Bank, joins Counting the Cost via Skype from Kathmandu to talk about aid efforts and the economic cost of Nepal's earthquake. He also discusses with Al Jazeera's Kamahl Santamaria whether estimates can be made as far as costs go about the extent of the damage.
