Kate Adie introduces stories from Sudan, Calabria in southern Italy, Japan, the Californian city of Oakland and Tbilisi in Georgia.

The war in Sudan between its army and the paramilitary Rapid Support Forces has torn the country apart for more than 500 days. Civilians are bearing the brunt of the suffering as aid agencies have had their access blocked in many areas. Leila Molana Allen has seen how Sudanese volunteers are bringing food and medicine to communities now full of hungry, displaced and often traumatised people.

The countryside of Calabria, in southern Italy, may look like a rural idyll. But much of its fertile agricultural land has been infiltrated by the local mafia network known as the Ndrangheta. Francisco Garcia met and talked to farmers trying to resist the organised crime groups which want to muscle in.

There's a record number of abandoned homes or 'akiyas' in Japan. Over 9 million houses are standing empty, as the population ages and shrinks, and younger people move to the cities. Particularly in rural areas, many heirs aren't prepared to take on the costs of emptying, demolishing or rebuilding old family homes. Shaimaa Khalil stepped into a couple of period properties now being restored by their new owners.

The city of Oakland, in northern California, once had a reputation for its political militancy and cultural inventiveness. These days it's known for bitter disputes over gentrification, homelessness, and public fear of crime. Lindsay Johns recently visited the city across the bay from San Francisco with of one of its most famous sons, author Ishmael Reed.

And in the shadow of the Caucasus Mountains, Beth Timmins attends not one, but three Georgian weddings - occasions full of heritage, music, poetry and toasts of thick red wine.
