What’s it like to live in a country on the sharp end of climate change? Today Tamasin Ford takes you to Sâo Tomé and Príncipe, the twin island nation in the gulf of Guinea. With the smallest economy in Africa, it has few means to fight what the UN calls the biggest threat modern humans have ever faced. We hear from coastal communities whose homes have been washed away because of rising sea levels.

President Carlos Vila Nova, who spoke at the United Nation’s climate conference in Glasgow last year, lays out the challenges small island nations face. While Luisa Madruga from the charity, Flora and Fauna International, explains how a new initiative could save fish stocks from disappearing altogether.
