What is believed to be the main cause of the bantu migrations that contributed to growth in south africa?

They needed more land for a growing population.

Explanation:

The Bantu were an African group of people who spoke various dialects of the Bantu language. These people originally came from the area around the Niger River in southern West Africa. From this region, they expanded throughout central, eastern and southern Africa. They took their traditional practices, language and technology with them, influencing the whole continent. However, the precise dynamics of the migration, as well as the specific reasons for it are not well-known.

the answer is c sharecroppers were trapped in a cycle of poverty and debt.

explanation:

one of the major disadvantages of sharecropping system is that the sharecroppers or the planters are stucked in an unhealthy cycle of debts. this happens because planters will be allowed to loan merchandise from the land-owner and will soon be paid by the farmer in his share in the farm come harvest time. hope this !
