Help the hungry more efficiently

摘要

Two years ago, the UN's Rome-based Food and Agriculture Organisation (FAO) appealed for $9m to spray locust larvae in the Sahel, the vast zone that runs just south of the Sahara desert, from the Atlantic in the west to the Horn of Africa in the east. The money never came. Or not enough. The larvae became locusts. The locusts swarmed. By the summer, the FAO needed $100m to undo the damage.
