More African vegetables on more plates

What will be the new food frontier? An article in the Wall Street Journal with the headline “Next Stop for Food Fanatics: Africa” predicts adventurous American palates may soon be craving sub-Saharan cuisines.

Besides making me hungry, reading this article made me think of some of the African vegetables that I’ve recently started to learn about. Yes, just as there are "Asian vegetables," there is also a wide category of "African leafy vegetables."

Have you heard of these?

• Nakati (Solanum macrocarpon, S. aethiopicum) Also called African eggplant, some types of nakati are eaten for their leafy greens, while others are eaten for their fruit (which can look like a tomato or eggplant).
• Cowpea leaves (Vigna unguiculata) This plant produces black-eyed peas, but the greens of the plant can also be eaten as a vegetable.
• Bbuga (Amaranthus Gracecizans) You might know this plant by its common American name: pigweed.
• Doodo (Amaranthus Dubius) Like bbuga, this type of amaranth is eaten for its leaves in many parts of Africa. In North and South America, varieties of amaranth are usually used as a grain.
• Jjobyo (Gynandropsis Gynandra, Cleome gynandra) Also called spider plant.

Many of these indigenous vegetables are rich in micronutrients such as iron, vitamin A and vitamin B. When it comes to alleviating malnutrition in developing countries of eastern Africa, indigenous vegetables offer workable solutions because they are not only nutritious, but also familiar to the region’s eaters and farmers.

But research into these vegetables has often not been a priority, even among international development professionals. Markets for these vegetables are also largely undeveloped because they are widely considered subsistence crops, often grown in small garden plots by women for their own families. But growing these crops commercially can mean increased income for smallholder farmers and improved nutrition for consumers who crave traditional foods.

Recently U.S. researchers have been working with indigenous crops like these in east African countries — with funding and support from the Horticulture Collaborative Research Support Program (Horticulture CRSP), led by Beth Mitcham at UC Davis with funding from USAID. In Kenya, Tanzania and Zambia, Stephen Weller of Purdue University is leading a Horticulture CRSP research project on production practices, seed resources, postharvest handling, marketing and nutrition of varieties of amaranth, spider plant and African nightshade.

In Uganda, Kate Scow of UC Davis is partnering with local groups to try out a new model of extension while increasing production of indigenous greens, such as nakati, bbuga and jjobyo.

Take a look at this short video for a little more background:

Just as bok choy, an Asian vegetable, has become familiar to many American households, perhaps one day you’ll find nakati or another African leafy vegetable on your plate.

In the meantime, researchers with Horticulture CRSP are working to get more African leafy vegetables into the research agendas, fields, markets and plates of our counterparts in eastern Africa.
