Can Soup Change the World?
Detroit Soup is an innovative crowd-funding dinner which is bringing people together to raise thousands of dollars for community projects in Motor City.
Since it launched five years ago, it has raised more than $85,000 for a range of start-ups working in areas such as urban agriculture, social justice and education - projects funded by, and for, the people. But could this model work in other cities?
For the BBC's A Richer World season, the BBC takes Detroit Soup founder Amy Kaherl to Nepal, to inspire a new crowd-funding culture Kathmandu-style.
Amy meets a team of kindred spirits in the Nepalese capital, intent on improving their community for the better. This results in the launch of the inaugural Idea Fest Nepal - but is such grass-roots activism sustainable in one of the world's poorest countries?
