Fonio
Fonio is the term for two cultivated grasses in the genus Digitaria that are notable crops in parts of West Africa.[1] They are millets with small grains.[1]
Fonio is a nutritious food with a favorable taste.[1][2] It is consumed mainly in West African countries, where it is also cultivated.[1][2] The global fonio market was 673,000 tonnes in 2016.[3] Guinea annually produces the most folio in the world, accounting for over 75% of the world's production in 2019. [4] The name fonio (borrowed by English from French) is from Wolof foño.[5]
In December 2018, the European Commission approved commercialization of fonio as a novel food in the European Union, after submission by the Italian company Obà Food to manufacture and market new food products.[6][7]

Types
White fonio
White fonio, Digitaria exilis, also called "hungry rice" by Europeans, is the most common of a diverse group of wild and domesticated Digitaria species that are harvested in the savannas of West Africa.[1] Fonio has the smallest seeds of all species of millet.[1] It has potential to improve nutrition, boost food security, foster rural development, and support sustainable use of the land.[1]
Nutritious, gluten-free, and high in dietary fiber,[1][2][8] fonio is one of the world's fastest-growing cereals, reaching maturity in as little as six to eight weeks.[1] The grains are used to make porridge, couscous, bread, and beer.[1]
Black fonio
Black fonio, D. iburua, is a similar crop grown in several countries of West Africa, particularly Nigeria, Togo, and Benin.[1]
Cultivation and processing
Fonio grows in dry climates without irrigation, and is unlikely to be a successful crop in humid regions.[1] It is planted in light (sandy to stony) soils, and will grow in poor soil.[9] The growth cycle ranges from 70-130 days, depending on variety.[10] Fonio has C4 carbon fixation, like many other grasses. They are medium in height.[11] The ploidy level for the species range from diploid (2n), tetraploid (4n), to hexaploid (6n).[12]
Fonio is labor-intensive to harvest and process. Men and boys use sickles to cut down the fonio, which women then gather into sheaves and set out to dry.[13] Then it is threshed by spreading it on straw mats or tarps, typically by women using their feet. The grains are then washed by hand.[8]
The small grains make it difficult and time-consuming to remove the husk.[1] Traditional methods include pounding it in a mortar with sand, and then separating the grains and sand,[14] or "popping" it over a flame and then pounding it, which yields a toasted-color grain (a technique used among the Akposso).[1] The invention of a simple fonio husking machine offers an easier mechanical way to dehusk.[15]
