Land reform in Zimbabwe began after the signing of the Lancaster House Agreement in 1979 in an effort to more equitably distribute land between ... blacks and the minority-whites who ruled Zimbabwe from 1923 to 1979.
The results of the post-2000 land reform have been disastrous for the economy of Zimbabwe. Prior to land redistribution, land-owning farmers, mostly white, had large tracts of land and utilized economies of scale to raise capital, borrow money when necessary, and purchase modern mechanised farm equipment to increase productivity on their land. The reforms broke this land into smaller tracts (thereby destroying the economies of scale) and gave it to former black farmworkers and peasants

I'm pretty sure their government has much more to do with the hyperinflation.
