Tracking agricultural land loss with NLCD

Interactive map of Ohio agricultural land-cover change from 1985 to 2024.

This tool uses Annual NLCD land-cover rasters to compare agricultural land across any pair of years from 1985 to 2024. It maps gross loss, gross gain, net loss, and agricultural land converted to development, with statewide and county-level summaries.
