Migrant workers' remittances provide a lifeline for millions in the world's poorest countries.
But the global economic crisis is cutting that lifeline for many people.
The flow of remittance money is drying up - and increasingly it's the workers themselves - rather than their wages - that are heading home.
The small Central American country of Honduras is one of the poorest in the western hemisphere and depends for almost thirty percent of its income on remittances.
In this programme we hear from Honduran migrant workers in the U.S.
who are struggling to find jobs - and from their impoverished families back home.
