What challenges do people in africa face with regard to water and agriculture?

Water scarcity is a reality in the world, dozens of countries are already facing this problem, which has been evidenced in the north-central African continent.

The lack of water is due to the fact that the reserves are finite, and the amount available is decreasing. In addition, the demand has been increasing due to population growth.

In sub-Saharan Africa rural activity is export oriented, so there is a large number of monoculture crops of tropical produce.

The plantation system, tropical crops that occupy large tracts of land, is a mode of production introduced by European settlers in the second half of the nineteenth century. In contemporary times this practice continues to be developed on huge farms, which are not owned by the native peoples, on the contrary, they belong to foreign companies or to rich white farmers of European descent.
