But as the rising power shifts towards advanced industry and away from traditional agriculture, donkeys are in decline. State statistics show the population has fallen
from 11 million to six million over the last 20 years.
China is now increasingly looking to Africa to boost its stocks, and imports donkeys from countries across the continent. But flourishing trade has hit several roadblocks.
Niger recently became the latest African state to ban exports of donkeys, following a surge in sales to China.
Government officials reported
that 80,000 animals had been sold in the first 9 months of 2016, compared with 27,000 in 2015, and warned that the donkey population would be "decimated" on current trends.
In August, Burkina Faso took the same step, after 45,000 donkeys were slaughtered in six months from a total population of 1.4 million.
In both cases, the value of donkeys soared and the fledgling industry delivered a valuable stream of foreign currency. But growth came at a cost.
Beyond the severe damage to donkey populations, the new industry caused environmental and economic problems.
The spread of abattoirs generated a backlash. In the Burkinabe village of Balole, local farmers reportedly attacked
and closed a slaughterhouse in protest at blood and offal leaking into their water supplies.
The donkey boom also attracted farmers from other livestock trades, which suffered as a result, and were also affected by inflation.
"In Niger and Burkina Faso the rising value of donkey hide and meat created inflationary impact in other sectors," says Dr. Emmanuel Igbinoba. "The price of other animals rose because of the donkey, not because there was demand for this animal, which caused imbalance in the economy."
