'Above Water': Aïssa Maïga explores consequences of drought in northern Niger

She's famous for her success as an actress in France, but Aïssa Maïga has now gone behind the camera to show how water shortages in one West African village have knock-on effects for the whole community. As her film "Above Water" is released in France and across Africa, she joins us in the studio to discuss how the situation in Niger is demonstrative of a deep inequality between the countries who have contributed to the climate crisis and those who feel the effects most acutely.
