Notes

1. In Sudan, for example, the parastatal Mechanized Farming Corporation has been awarding fifteen-year leases only to people who clear 85 percent of their assigned holdings in three years (Southgate 1990).

2. See Raintree (1987) for a number of detailed tree tenure studies in SubSaharan Africa.

3. There are exceptions—still found, for example, in southeastern Nigeria or western Sudan—where individuals and families may be given access to an amount of land but not to a specific plot. In such systems, where use rights for cultivation of seasonal crops rotate each year or after several years, individuals may not be keen on making long-terrn investments in land improvement (Migot-Adholla and others 1989).
