In the five years reviewed in this study (1950-1954), most parts of Africa experienced an increase in the level of economic activity. The total value of exports, the main source of money income in Africa, increased considerably. At the same time, expenditure on post-war development plans has been at a high level. These development expenditures have been financed in part - largely in French territories - by funds from external sources and have thus been additional to export earnings. There has also been considerable public foreign investment, particularly in central and southern Africa. Chapter 1. Introduction -- Chapter 2. Agricultural production -- Chapter 3.
