Women using satellites to track coastal erosion

Rising sea levels and increasingly powerful storms are threatening coastlines, low-lying island states and coastal cities around the world. Ella Al-Shamahi talks to two women from Sri Lanka and France about how they’re using satellites to track coastal erosion and develop strategies to reduce its impact on populations.Sarah Dole is a Sri Lankan physicist and entrepreneur leading a satellite image analysis project in the Maldives, the world’s lowest lying country, looking at the rate at which beaches erode. She co-founded Invena – a company carrying out research and helping develop technology that aims to preserve low-lying nations.Anne-Laure Beck is a French geomatic and remote-sensing engineer. She's the EU lead on coastal erosion for the environmental consultancy Argans. They use satellite-based earth observation and geographical information systems to map and monitor environments in order to track coastal erosion and accretion to inform coastal management and protection plans.Produced by Jane ThurlowImage: (L) Sarah Dole credit Ali Amir @aliaerials.
