Remittances "can empower rural people to blaze a trail out of poverty and exclusion," said Kanayo F Nwanze, President of the UN International Fund for Agricultural Development (IFAD).
"The value of remittances is staggering, but the rural poor need greater impact," Nwanze said, underscoring that "we need more strategic ways to invest the USD 200 billion sent home to the rural areas every year".
More than 215 million people across the globe live outside of the countries they call home.
Most remittance families operate outside of the world's financial system, dependent on costly cash transfers that often require significant travel for rural recipients.
