Sustainable Nitrogen Management (EPI_NITROG)

An index measuring the sustainability of Nitrogen management based on Nitrogen use efficiency (in agriculture) and land use efficiency (crop yield). The Sustainable Nitrogen Management Index (SNMI) seeks to balance the efficient application of nitrogen fertilizer with maximum crop yields as a measure of the environmental performance of agricultural production. The 2022 EPI uses the SNMI as a proxy for agricultural drivers of environmental damage.
