Paradoxically, African Railroad Keeps Habitat Intact

When a series of cyclones buried large portions of a railroad in Madagascar it was doubtful that resources could be found to repair it. But a cost-benefit analysis showed that only the railroad could save the forest. Without it local farmers would turn from cash crops that needed to be shipped to slash-and-burn subsistence farming in the forest. Because of that analysis donor groups were found that made the railroad repair possible.
