Neglected and underutilised crops are domesticated plant species used for food, medicine, trading, or cultural practices within local communities but not widely commodified or studied as part of mainstream agriculture.
[3] They are considered underutilised in scientific inquiry for their perceived potential to contribute to knowledge regarding nutrition, food security, genetic resistance, or sustainability.
[10][11] Alongside their commercial potential, many underused crops such as sorghum provide essential environmental services as they have adapted to marginal soil and climate conditions.
[12] Underutilised crops continue to play a vital role in the subsistence and economy of people in low and middle-income countries, particularly in the agro-biodiversity rich tropics.
These species may be widely distributed beyond their centers of origin but tend to occupy unique niches in the local production and consumption systems.
