Forestry in FAO
This issue of Unasylva focuses on the fortieth anniversary of FAO - -and, in particular, on 40 years of work by FAO's Forestry Department.

Forestry and the crisis in Africa
This issue of Unasylva focuses on Africa. A large part of the continent has been overrun by drought in successive years, and millions of people are exposed to hunger and malnutrition.
