How has botany been able to function as one of the longest-lasting soft powers between the two world powers - China and the US? Journalist and producer Finn Aberdein has been focused on China for over two decades. He hears from policy analysts, supply chain diplomats and leading Chinese and US botanists working tirelessly to keep their boots on the ground trips operating. From the secretive walled-gardens of China’s communist elite, to the gingko picnic spaces of Bostonian college lawns, and ancient forest canopies of the Sichuan basin, a portrait emerges - one of a borderless community of plant specialists practising a special kind of soft power. How has the quiet work of botanists helped weather political storms?

When it opens in December, the Wallis Annenberg Wildlife Crossing will be the largest in the world. Stretched over a 10-lane freeway, it is intended to help save California's mountain lion population, which has become fragmented by the highway. It could also serve as a model for other projects, as crossings of this kind have often been viewed as too large to be effective. But will the crossing work? We examine the construction and the existing scientific data to find out.

The Victoria falls, on the border of Zambia and Zimbabwe, is considered one of the natural wonders of the world. But as Isa Jacobson reports, there is concern that development around the waterfall could threaten the delicate ecosystem and exacerbate conflict between humans and wildlife.

South African police detective Frans Mathipa told his boss he feared that he would be killed by the country’s military. Two days later he was found shot dead in his car by the side of a motorway.
At the time of his death, Mathipa had been investigating whether special forces soldiers were behind the disappearance of Abdella Abadigga, a suspected member of so-called Islamic State or ISIS, and his bodyguard. So was Mathipa killed, as his colleagues believe, because of fears about what his investigation threatened to reveal?
Dino Mahtani and Yeshiel Panchia investigate an extraordinary case that sets one arm of the South African state against another.

In Lagos, a vast patch of scrubland is being imagined as the future home of Kebulania: an ambitious African film city on the edge of Nigeria’s biggest metropolis, and one of the centres of Nollywood, the country’s multi-billion dollar film industry. Nigerian journalist Samuel Okocha follows the project in its earliest, most uncertain days – when the vision is big, but the buildings are yet to rise. At the proposed site, he joins community members, contractors and staff from Del-York Creative Arts, a Nigerian conglomerate film and media training company, as traditional leaders offer prayers and blessings.
