Overview

, account for approximately 50% of the world's consumption of calories and protein, and about 95% of the world's food needs are provided by just 30 species of plants. Despite this, the list of crop species compiled as edible extends to around 12,650. Among these are plants that have been used for food and other uses on a larger scale historically, but whose usage has dropped in modern times.

adaptation to climate change, etc.), some previously neglected crops, such as

Definition
There is no consensus on what defines an underutilised crop, but they often display the following attributes:
* Linkage with the cultural heritage of their places of origin
* Local and traditional crops whose distribution, biology, cultivation and uses are poorly documented
* Adaptation to specific agroecological niches and marginal land
* Weak or no formal seed supply systems
* Traditional uses in localized areas
* Produced in traditional production systems with little or no external inputs
* Receive little attention from research, extension services, policy and decision-makers, and consumers
* May be highly nutritious and/or have medicinal properties or other multiple uses
Neglected crops are primarily grown by traditional farmers. These species may be widely distributed beyond their
centers of origin but tend to occupy unique niches in the local production and consumption systems. They are critical for the subsistence of local communities yet remain poorly documented and neglected by mainstream

Examples

Determination of the underutilized status of a crop varies among researchers. Different criteria and approaches are used to define this particular group of crops.
Neglect refers to the lack of attention a crop may receive through research and development and can be evaluated by how well national and international policy or legal frameworks and research and development programs can support the conservation and sustainable use of a crop. Underutilisation is particular to the geography and potential for a crop to contribute to better diets and production systems. In cases where exotic or diversified species are underutilised in a particular region, these may not necessarily be underutilised in other parts of the world.
Below is a non-exhaustive list of neglected and underutilised species.
It is important to recognise the potential negative impact on communities that historically use so-called underutilised crops. For example, as
