 Sub-Saharan Africa is a lot like the half empty, half full glass. Although the region has many problems, it holds much hope for the future. On one hand, political and economic problems plague the region.

   The region's cities attract a high number of immigrants, increasing diversity as well as the ethnic conflict in the region. Population growth is putting a tremendous strain on the environment. Because of population growth, there are water shortages, unemployment, lack of housing, and inadequate services. On the other hand, there are still large areas of land that can be farmed to feed the population and provide crops for export.

   Governments are stabilizing, but government systems lack capacity, and representative government is increasing. Some government systems in the region are unstable. Many governments are unable to provide adequate services. Ethnic diversity and conflict continue to plague the region. On the other hand, most government systems are moving toward democratic, multiparty systems in which leaders are elected.

   Economic development is increasing, yet, there are many factors that describe the political situation that Sub-Saharan Africa is facing such as international debt, and weak government systems that hinder economic development. There are positives though. Foreign investment will aid the region's economic development, and globalization will play a role in the region's economic future. Technological advances will also expand employment opportunities. There are several methods dealing with water issues that affect the economics of the region. Water is moved from an area where it is abundant to an area experiencing a shortage, and desalinization is being implemented.

Social services are also improving. Nevertheless, there are a number of regional issues that must be addressed. Health issues in the region include malaria, schistosomiasis, and AIDS. Progress is being made, particularly in urban areas where clinics offer basic care. The status of women also varies throughout the region.
