Earth Reporters : My City and Your City

St Louis, Senegal's historic former capital, is the city most threatened by rising sea levels in the whole of Africa. Every rainy season, thousands of people face upheaval from flood devastation. The city's Mayor, Cheikh Mamadou Abiboulaye Dieye is our Earth Reporter. He shows us the problems in St Louis -- and we follow him as he brings the plight of his city to the World Mayors Summit on Climate in Mexico City. Produced with the support of UNISDR and ECHO.
