  • An operational satellite-based monitoring system using NASA/USGS and ESA imagery enables rapid tracking of global land change, with the area of conversion due to direct human action and fire equaling the size of California in 2023.

  • Changes in agricultural practices have led to the expansion of tree plantations across the tropics, but this expansion is poorly characterized. Nearly 7 million unique patches of observed tree cover gain are classified through satellite imagery to report on tropical tree plantation expansion between 2000 and 2012.

  • High-resolution satellite observations provide an accurate and cost-effective solution to monitoring national and global progress towards Sustainable Development Goals. With a new global cropland dataset, this study reports that during the first two decades of the twenty-first century, the global cropland area increased by 9%, whereas the per-capita cropland area decreased by 10% and the per-capita annual cropland net primary production increased by 3.5%.

  • Deforestation is often driven by land conversion for growing commodity crops. This study finds that, between 2000 and 2019, most soybean expansion in South America was on pastures converted originally for cattle production, especially in the Brazilian Amazon. More soy-driven deforestation occurred in the Brazilian Cerrado.

  • Forest management for climate mitigation plans requires accurate data on carbon fluxes to monitor policy impacts. Between 2001 and 2019, forests were a net sink of carbon globally, although emissions from disturbances highlight the need to reduce deforestation in tropical countries.

  • Satellite data for the period 1982–2016 reveal changes in land use and land cover at global and regional scales that reflect patterns of land change indicative of a human-dominated Earth system.
