The "elimination of rain dance rituals by African tribes" doesn't contribute to the "problem of desertification" in Africa.

Explanation:

The rituals that are performed by the tribal are based on beliefs and apparently have nothing to do with the earthly phenomena like desertification or raining. The reasons behind the severing of the problem of desertification in Africa are broadly related to the change in climatic conditions, overgrazing by the livestock and rapid deforestation.
