Brazil's huge river diversion project divides opinion

Outside his house by the Sao Francisco river, Emanoel de Souza toys with the skin of a crocodile he hunted a month earlier. "There are plenty out there. You leave a cow's heart on a hook by the river, and by morning a crocodile will have bitten," he smiles. The meat makes for a good meal and the skin provides an amusing decoration. But de Souza gets much more than crocodiles from the Sao Francisco. The river also provides water for him to farm fish and rice. The profits of the last harvest alone paid for a new motorbike. This makes him one of the lucky ones. Just a few kilometers away, out of reach of the Sao Francisco's water, Raquel Torres has lost a crop of beans and maize due to lack of rain.
