Eastern and Southern Africa




The Center’s African regional program began in 1992 in Arusha, northern Tanzania. Today AVRDC has professional research and development staff working across Africa on important vegetable crops such as tomato, pepper, onion and cabbage, as well as a range of African traditional vegetables, and partners with more than 40 national institutions and many international organizations.

AVRDC Eastern and Southern Africa, Arusha, Tanzania

The Center operates two regional bases: in Tanzania for Eastern and Southern Africa, and in Mali for West and Central Africa. There is a liaison office in Cameroon to reach into sub-Saharan Africa with improved vegetable varieties and production technologies.

The vegetable sector in sub-Saharan Africa is severely underdeveloped and vegetable consumption is extremely low. In Africa’s diverse agroclimatic zones, there is enormous potential for smallholder farmers to produce numerous vegetable crops for domestic and international markets.

Vegetables are often the most important source of cash income for smallholder farmers, and indigenous vegetables provide an important source of nutrition, particularly for poor people. New varieties and improved management methods have been developed and extended through training programs for research and extension workers and smallholder farmers.

AVRDC Eastern and Southern Africa is currently active in the following countries:

  • Tanzania
  • Kenya
  • Zambia
  • Ethiopia
  • Malawi
  • Mozambique
