Abstract: Ecological footprints have been assessed widely from a resource production-consumption perspective but much less from a land use per capita availability-demand standpoint. The later view is key to land use policy because it sheds light on the need of changing or adapting uses to get a balance between those of ecological (e.g., forests, riparian wetlands) and those of socioeconomic (e.g., cropland) value. Thus, the purpose of this study was to introduce the LUEF – Land Use Ecological Footprint, defined as the area of a specific use or occupation in a region over the population of that region in a pre-defined timeframe. The index was then applied to the Brazilian territory at the macro region resolution, and to the 2015 – 2019 period. The results identified deforestation, urban densification, cropland/pasture expansion and riparian forest restoration as main drivers of LUEF change in the studied period, as well as supporters of concomitant gross domestic product. The results also revealed negative consequences of LUEF changes for water security and organic carbon stocks in the top layer of soils (decline). Some regional metrics were proposed to revert these consequences, namely the control of urban LUEF above 100 m2/hab to keep water security at the National average level, and of cropland LUEF below 900 m2/hab to preserve organic carbon stock in the macro regions’ topsoils close to the National average (46.9 Mg/ha), reducing greenhouse gas emissions in the sequel. The leveling of those LUEFs at the aforementioned values requires intensification of ongoing policy initiatives relevant to mitigate the land use ecological footprints. The study identified various examples, which included the Brazilian Forest Code, the National policies on urban and family agriculture, Payment for Ecosystem Services programs, among others. Overall, the study recognized Brazil as being in the right track to pursue sustainable land use.
