On Australia's northern doorstep lies one of the most extraordinary places on earth – some environmentalists call it the second Amazon. The Sepik River Basin in Papua New Guinea is a natural wonder and home to rich and ancient cultures. It's a place few outsiders ever get to see. For some time, PNG correspondent Natalie Whiting has been hearing rumours about what's going on in the remote areas upriver – claims of a logging land grab, police brutality, even killings. This week on Foreign Correspondent she undertakes the journey far up the Sepik River to see for herself what's happening.

In the rainforest of the Upper Sepik a community is divided. Logging operations and a proposed massive mine site bring hope of economic prosperity for some. But others fear development of the land by international companies means environmental destruction with little benefit. PNG is the world's largest exporter of tropical round logs but out of sight in the Sepik region some landowners say the logging is happening without proper consent and there are consequences for those who stand in the way. With a long history of mistrust of big corporations and the promises they make, many of the locals are angry and ready to do whatever it takes to preserve some of the most unspoilt rainforests and waterways on the planet.

Somalia is one of the most dangerous places on earth. Almost two decades of conflict with the al-Qaeda backed terrorist group al-Shabaab has taken a huge toll on the country. Now Somalia is experiencing its worst drought in 40 years. With the world distracted by the war in Ukraine, the crisis is escalating away from the public gaze.

This week on Foreign Correspondent reporter Stephanie March and producer/cinematographer Matt Davis travel to Somalia where makeshift camps have become home to more than a million hungry children and their families. There, they meet mothers with babies who have walked for days without food and very little water. They hear incredible stories of courage and survival in a landscape that is unforgiving and unsafe. And they also face their own safety problems when their security team worries al-Shabaab has been told of their whereabouts.

As the Somali government fights back against al-Shabaab, another threat, which they have no control over, is driving the extreme weather: climate change. In the midst of this turmoil, the Foreign Correspondent team meets extraordinary people who are determined to make their story one of survival.
