Greening Beira, Mozambique
Daviz Simango is one of Mozambique's most influential politicians but last year when yet another flood inundated Beira, the coastal city he has served as mayor since 2003, he felt powerless.
"Disasters like that happen all the time in our city but last year was the worst for me - it felt like we're trapped in an endless cycle of disaster after disaster," Simango said.
Simango, who has stood in presidential elections in the southeast African country and is the founder-president of its third-largest party, the Democratic Movement of Mozambique (MDM) has embarked on an ambitious plan for his city, the country's second largest.
Like many African coastal cities, Beira - which lies just above sea-level - is in a race against time to protect itself from cyclones, floods and rising sea-water levels.
