Africa on the Move: Oyster Farming in Senegal - Many people in Senegal depend on agriculture and aquaculture to make a living - with most of those involved working illegally. The country's economy has suffered from both chronic mismanagement and the effects of extreme weather - meaning hunger is a major concern for the population. People living along the Casamance River depend on rice production and logging for their livelihood. Now, one initiative is looking to help women earn a living via oyster farming - and protect the mangrove forest. With the help of a small loan, the project's leader Seynabou Diatta is pursuing an environmentally friendly way to harvest oysters. Bangladesh: Adapting to Climate Change - Bangladesh is one of the poorest countries in the world - and people here are among those suffering the most from the effects of climate change. Large swathes of land have been ruined through excessive shrimp farming - leaving too much salt in the soil. Women have been hardest hit by the problem. Sharmind Neelormi and Ahsan Achmed from the Centre for Global Change (CGC) help support a series of village committees in southeastern Bangladesh. The salty soil here is barely arable during the dry season. CGC is supporting efforts to promote sustainable crab farming and to plant salt-resistant varieties of rice. Through these projects, women are helping raise environmental consciousness in a patriarchal society. Cuba - A New Face for Old Homes: Since assuming power, Fidel Castro's younger brother, Raul, has gradually started implementing liberal economic reforms. One reason is the 2.5 million tourists Cuba attracts each year. That's underscored the need to give crumbling building facades in the Cuban capital Havana a facelift. Havanna's historic center with its colonial-era buildings has significant architectural appeal. The city's charm is a major money-maker - and among the political changes being made is the liberalization of the real estate market. As of November, real estate can be bought and sold in Cuba, for the first time since the revolution. Global 3000 takes a look at the dilapidated state of most buildings in the capital - and the efforts being made to renovate them and create new places to live.
