Fonio

language culture Maturity 5-7 Next article →

Fonio is a vital group of cultivated grasses from the genus *Digitaria*.

These grains are essential food sources in many rural parts of West Africa. They are particularly important in the mountains of Fouta Djalon in Guinea. Fonio is also grown in Mali, Burkina Faso, Ivory Coast, Nigeria, and Senegal. The name comes from the Wolof word *foño*. While many species of crabgrass exist in the *Digitaria* genus, only a few are grown for their grains. Fonio is a small, annual herbaceous plant. It belongs to the grass family known as Poaceae.

The plant grows using a specialized biological process called C4 carbon fixation. This process helps the plant stay tolerant during dry periods. Fonio is very well adjusted to harsh environments and poor soils. Its root system is quite deep and can extend more than one meter into the ground. This depth helps the plant survive during droughts. The plant has an inflorescence, which is a cluster of flowers. This cluster contains two or three racemes, or flower stalks. Each raceme has spikelets grouped in twos, threes, or fours. These spikelets contain a sterile flower and a fertile flower that produces the actual grain.

There are two distinct types of fonio cultivated in West Africa. The first is white fonio, or *Digitaria exilis*.

This is the most economically important variety. It is sometimes called "hungry rice" by Europeans because it matures so quickly. The second type is black fonio, or *Digitaria iburua*. This variety is grown in countries like Nigeria, Togo, and Benin. Black fonio contains considerably more protein than white fonio. While white fonio is a major commercial crop, black fonio is mostly grown in rural communities and is rarely sold in cities.

Growing fonio involves a specific sequence of labor-intensive steps. First, the land is ploughed by men using hands, animal traction, or tractors. Next, women generally sow the seeds by hand depending on the rainy season. Because the plants are weak competitors against weeds early on, weeding is a necessary step. The plants grow very fast, with some reaching maturity in only eight weeks.

During the harvest, workers use knives or sickles to cut the straws. This can be difficult work that often causes wounds on the hands. After cutting, women gather the sheaves into stacks to dry. The threshing process involves trampling the plants or beating them with sticks or rods.

Processing the grain is the most time-consuming stage because the seeds are so small. After threshing, the grains are still trapped inside a husk. Traditional methods for dehusking include pounding the grain in a mortar with sand. Some groups, like the Akposso, use a technique called "popping" over a flame. This results in a grain with a toasted color.

Gender roles are very clear during this production. Women handle weeding, threshing by trampling, cleaning, and drying. Men typically handle the harvest and threshing by beating. About half of all cultivation tasks are performed exclusively by women.

How you cook the grain changes its nutritional value. For example, the carbohydrate content stays higher if you precook the grain rather than roast it. Roasting increases the lipid, or fat, content of the grain. However, milling the grain can lower the protein content because the bran is removed. The highest protein and mineral levels, such as iron and zinc, are found in parboiled fonio.

Parboiling changes the color of the grain, which some consumers do not like. Despite this, parboiling is often considered the best method for nutrition.

Fonio has moved from being a local staple to a global product. In 2019, Guinea produced over 75% of the world's fonio. The global market for the grain was estimated at 721,400 tonnes in 2020. In 2017, the company Yolélé Foods began importing fonio to the United States.

In the European Union, the Commission approved fonio as a "novel food" in 2018. This allowed companies to create new products like fonio pasta. EU imports grew from 172 metric tonnes in 2016 to 422 metric tonnes by 2021. This growth shows how the world is becoming more interested in this ancient grain.
