Input use intensity measures the amount of a given input used per unit of area (e.g., kg nitrogen input/ha; liter of irrigation water/ha). Input intensity provides a measure of assessing two important issues: 1) whether a given input is used and 2) amount used per unit area. This indicator may also provide a sense of the community’s input usage  and assess the need to supply more (in cases where low levels are used) or in cases of overuse, explore options to advise farmers about how to reduce the amounts used or use the resource more efficiently.
