Nepal is among the poorest and least developed countries in the world, with more than half of its population living below the poverty line. Agriculture is the mainstay of the economy, providing a livelihood for three-fourths of the population and accounting for about one-third of GDP. Industrial activity mainly involves the processing of agricultural produce including jute, sugarcane, tobacco, and grain. Tourism is the chief source of foreign income. Nepal has considerable scope for exploiting its potential in hydropower and tourism, areas of recent foreign investment interest.
