Marginal land is land that is of little agricultural value because crops produced from the area would be worth less than any rent paid for access to the area.[1] Although the term marginal is often used in a subjective sense for less-than-ideal lands, it is fundamentally an economic term[2] that is defined by the local economic context. Thus what constitutes marginal land varies both with location and over time[3].
Land may be marginal for a number of reasons, including poor water supply, poor soil quality, pollution from previous industrial activities, terrain challenges such as excessive slope, or excessive distance from means of transportation.[4]
Marginal land is not entirely useless for human purposes. For example, certain breeds of free-roaming livestock, such as the English Leicester sheep, are able to forage on such land. There are also some plants that can be grown in land that would be considered marginal for most agricultural uses. For example, cucurbita foetidissima, the buffalo gourd, is well adapted to marginal agricultural lands such as sandy loam soils which have to be well-drained.[5][6] Land that is marginal for conventional row-crop production is often well-suited to perennial crops[7], including low-input crops grown as bioenergy or bioproduct feedtocks such as switchgrass (Panicum virgatum), shrub willow (Salix spp.), and giant miscanthus (Miscanthus x giganteus), allowing production of these crops without inducing competition for prime farmlands.
