This is a place of huge contrasts: futuristic modern cities jostling with traditional seaweed-thatched villages, ancient tea terraces and wild wetlands where rare animals still survive. Here Chinese white dolphins, red-crowned cranes, deadly vipers, giant sturgeon and sabre-wielding monkeys struggle to eke out a living faced by competition from 700 million people, widespread pollution and over-fishing. How China is managing such conflicting pressures has lessons for us all.

Four-part series in which British art historian Dr Gus Casely-Hayford explores the pre-colonial history of some of Africa's most important kingdoms. The African continent is home to nearly a billion people. It has an incredible diversity of communities and cultures, yet we know less of its history than almost anywhere else on earth. But that is beginning to change. In the last few decades researchers and archaeologists have begun to uncover a range of histories as impressive and extraordinary as anywhere else in the world. The series reveals that Africa's stories are preserved for us in its treasures, statues and ancient buildings - in the culture, art and legends of the people.
