The main way people use the land in Africa is subsistence farming. They don't do a lot of commercial farming which is important in Africa. Subsistence farming is when a farmer only grow enough food for their family, on the other hand commercial farming is when people farm to make a profit. This will cause a problem to other families who don't farm on their own, because Africa will not get a profit from crops if they don't sell anything. This will then lead to starvation. That is how they use the land and the problem that makes.

Democratic Republic of Congo
The problems in the Democratic Republic of Congo are that they have a bunch of natural resources, and they don't have any control over the resources. Armed rebel groups control the mines with the resources. The keep control by forcing people to work and smuggling and selling the minerals, which makes them money to buy weapons and bribe corrupt leaders in the government. The rebel groups bribe the leaders with money to stay out of the mines. These three minerals are the 3 "T's". These 3 "T's" are tin, tantalum, and tungsten. These minerals go into making all our electronics. No wonder the groups are so wealthy.

GDP Per Capita
There are five nations in Africa that have high GDP Per Capita. These five are Mauritius which their GDP is $12,800, South Africa which their GDP is $11,100, Botswana which their GDP is $9,200, Seychelles which their GDP is $7,800, and Namibia which their GDP is $7,300. There are also nations with pretty low GDP per capitas. There are 16 that had GDP's below $1,000. The reasons why the nations with the highest GDP's have higher ones than the nations under $1,000 is because they have better technology and more natural resources.

Slaves on the Trans-Saharan Network
North African Muslim tribes traded things for African slaves because Muslims can not enslave other Muslims. Muslim and African slave owners used there slaves in the military. The Muslim and African enslavement of Africans was different from Europe enslavement of Africans because they got more freedom. The Muslim slave owners let the slaves own land, be generals in the army, and gain their freedom easier.
