It's Christmas Day and following a year which has been harrowing for so many, we've decided to look back at the good news of 2020. We begin in Uganda, where a plastics company that specialises in recycling switched from making building materials to face shields to help hospitals. We also go to Benin, where the closure of the border with Nigeria has led to a push for more locally produced food, some of it on rooftops. And our correspondent in DR Congo looks back at how an NGO is helping Ebola survivors turn their lives around.
