Ibrahima Ka, dressed in flowing indigo robes, gathers his herd with those of his neighbours before a stretch of lush, untouched pasture. The bellowing, heaving and trampling of 350 impatient zebu cows behind a wire perimeter marks a break with centuries of herding tradition in Senegal, west Africa. Rather than roaming freely across the country’s vast grasslands, shepherds tightly pack the herd together, confining them to graze in short, intensive bursts before being moved to a new plot.
Ka, the village chief of Thignol, is spearheading the first pilot of “mob grazing” in Senegal, aiming to mimic, on a much smaller scale, how wildebeest flow across the Serengeti, moving to protect themselves against lions and cheetahs. The idea that intense grazing can regenerate grasslands rather than accelerate their decline has been controversial. Initially, proponents argued it could help to solve the climate crisis through storing carbon in regenerated grasslands – a claim with little scientific basis. But there is some evidence that the method can boost biodiversity and grassland health in dry areas such as Senegal.
