Globalisation can be described as a process by which the people of the world are unified into a single society. This process is a combination of economic, technological, sociocultural and political forces. Looking specifically at economic globalisation; it can be measured in different ways. These centre on the four main economic flows that characterise globalisation: Goods and services, e.g. exports plus imports as a proportion of national income or per capita of population; Labour/people, e.g. net migration rates; inward or outward migration flows, weighted by population; Capital, e.g. inward or outward direct investment as a proportion of national income or per head of population; Technology, e.g. international research & development flows; proportion of populations (and rates of change thereof) using particular inventions (especially 'factor-neutral' technological advances such as the telephone, motorcar, broadband). This volume centres on globalisation and its processes in Africa.
