Drought and desertification are closely related phenomena. Persisting over months or years, drought can affect large areas and may have serious environmental, social and economic impacts. While drought is a natural phenomenon, whose impacts can be exacerbated by human activities that are not adapted to the local climate, land degradation is the process of turning fertile land into less or non-productive land. In extreme cases in drylands this is called desertification. Land degradation and desertification are complex phenomena driven by un-adapted human activity in combination with land and climatic constraints. Inappropriate land use, such as monocultures, and unsustainable land management practices, such as deforestation, unsuitable agricultural practices and overexploitation of water resources), can cause land degradation that can be further aggravated by drought.

Africa is a continent that is abundant in resources. Some resources are in mineral reserves, such as gold, salt, and diamonds, while some resources are of other nature, such as the biodiversity, large and young labor force, and good location for trading. Despite being a continent that has lot of resources of all sorts, Africa in general is still underdeveloped, with the majority of the nations on it being poor. The main reason for this is mostly the bad and corrupt politics on the continent.

- The location of Africa is excellent for trade, as it is in touching distance of Europe, surrounded by water bodies that connect it with Asia, Australia, and the Americas.
- If the potential of the continent is properly used, Africa can be become a major player on the global economic scene, though lot of work has to be done for that to be achieved.
