Question

why is the population smaller in southwestern africa? sahara desert active volcanoes kalahari desert dense tropical rainforests

Explanation:

The Kalahari Desert is located in southwestern Africa. Deserts generally have harsh living conditions like arid climates, limited water resources, and difficult terrain for agriculture and settlement. These factors contribute to a smaller population in such regions. The Sahara Desert is in northern Africa, active volcanoes are not a major characteristic of southwestern Africa's population - reducing factor in a general sense for the whole region, and dense tropical rainforests are more associated with central and some western parts of Africa rather than the southwestern arid - desert dominated area.
