    Anatomy of Sahel drought

    Al Jazeera English

    by Al Jazeera English

    Between the vast Sahara desert and the dense foliage of the African rainforest is a band of semi-arid grassland.

    Known as the Sahel, this landscape is one of Africa's most productive crop regions.

    But the crops in the Sahel are grown close to their limits of tolerance, and rely on natural rainfall.

    This means that even small changes to the amount of rain can have disastrous effects.
