Fonio
A fast-growing, drought-tolerant West African cereal grain.
Fonio, also known as findi or acha, is the name for two types of cultivated grass from the genus *Digitaria* that serve as key crops across parts of West Africa. It provides essential nourishment in many rural areas, particularly in the Fouta Djalon highlands of Guinea, and is also grown in Mali, Burkina Faso, Ivory Coast, Nigeria, and Senegal. In 2020, the worldwide fonio market reached roughly 721,400 tonnes, and Guinea was responsible for more than 75% of global production in 2019. The English term "fonio" comes from the Wolof word *foño*, borrowed via French. In West Africa, farmers cultivate black fonio (*Digitaria iburua*) and white fonio (*Digitaria exilis*), with the white variety being the more economically significant crop.
Fonio is a glumaceous monocot in the grass family Poaceae, within the genus *Digitaria*. Although there are hundreds of species of this crabgrass, only a few are grown for their grain. It is a small, annual herbaceous plant whose flower cluster (inflorescence) bears two or three racemes. These racemes hold spikelets grouped in twos, threes, or fours, each containing one sterile and one fertile flower that produces the fonio grain. The plant has a short growing season and thrives in tough conditions. Its root system can extend over a meter deep, which helps it survive drought and adapt to poor soils. Once seen as a humble, overlooked grain often called the "cereal of the poor," fonio is now drawing attention in urban West Africa due to its cooking qualities and nutritional value, sparking renewed interest in this formerly underappreciated staple.
**Types**
**White fonio** White fonio (*Digitaria exilis*), sometimes called "hungry rice" by Europeans, is the most common among a diverse group of wild and domesticated *Digitaria* species harvested in West African savannas. It has the smallest seeds of any millet species. This grain has the potential to improve nutrition, boost food security, support rural development, and encourage sustainable land use. Nutritious, gluten-free, and high in dietary fiber, it is one of the world's fastest-growing cereals, maturing in as little as six to eight weeks. The grains are used to make porridge, couscous, bread, and beer.
**Black fonio** Black fonio (*Digitaria iburua*), also called iburu, is a similar crop grown in several West African countries, notably Nigeria, Togo, and Benin. Like whit

Lore & Background
Fonio is a glumaceous monocot in the grass family Poaceae and genus Digitaria. It is a small annual herbaceous plant with an inflorescence of two or three racemes; spikelets are grouped in twos, threes, or fours, with a sterile and a fertile flower producing the grain. Its root system can extend more than one meter deep, aiding drought tolerance and adaptation to poor soils. White fonio (Digitaria exilis) is the economically more important species, while black fonio (Digitaria iburua) contains considerably more protein but is rarely sold commercially.
Cultivation is labor-intensive. Ploughing is done by men by hand, animal traction, or tractors; sowing is generally done by hand by women. Weeding is critical early on, as fonio is a weak weed competitor. Harvesting involves cutting straws with knives or sickles, then drying and threshing by trampling or beating. Dehusking is difficult due to small grain size; traditional methods include pounding with sand or popping over a flame. A simple husking machine now offers mechanical dehusking.
Gender roles are pronounced: women do weeding, threshing by trampling, cleaning, drying, and processing; men do harvest and threshing by beating. Half of cultivation tasks are exclusively done by women, 14% by men. Processing methods affect nutrient value: parboiling yields the highest protein, iron, and zinc content, though it changes grain color, which some consumers dislike.
Reader's Guide
Fonio has long been a humble staple in rural West Africa, often called the 'cereal of the poor,' but is now gaining attention in urban areas for its unique cooking properties and nutritional benefits. It is gluten-free, high in dietary fiber, and one of the world's fastest-growing cereals, reaching maturity in as little as six to eight weeks. Its C4 carbon fixation and deep root system make it drought-tolerant and well-suited to harsh, dry climates and poor soils.
Despite its agricultural advantages, fonio remains labor-intensive to harvest and process, which has limited its commercialization. However, recent developments are changing this. In December 2018, the European Commission approved fonio as a novel food, and by 2021 EU imports had risen to 422 metric tonnes. In the United States, Yolélé Foods began importing and selling fonio in 2017, aiming to support sustainable agriculture in West Africa. The grain's potential to improve nutrition, boost food security, and foster rural development is increasingly recognized, though challenges remain in mechanization and consumer acceptance of processed forms.
