“…For instance, a recent study on land use change utilizing three periods of remote sensing imagery revealed that the total area of abandoned cropland in the study area from 2000 to 2020 was 36,725 km 2 . However, our findings demonstrate that when considering the presence of fallow, the total area of abandoned cropland is only 30,500 km 2 [34]. This reflects the quantitative differences resulting from changes in assessment methods, reminding us to fully consider the complexity and variability of land use types.…”

“…This non-linear temporal dynamic in land systems is closely related to policies and economic development [18,34]. Around the beginning of the 21st century, the Chinese government launched a series of projects to restore natural vegetation, including the Returning Farmlands to Forest and Grassland Project (also known as the "Grain to Green Program", GGP) and the Beijing and Tianjin Sandstorm Source Treatment Project (BTSST).…”

The farming–pastoral zone in northern China is one of the most ecologically sensitive areas globally, having experienced extensive cropland abandonment and land reclamation over decades, primarily influenced by policy adjustment and global warming. However, the spatiotemporal patterns and suitability of long-term cropland change remain poorly understood. Using the annual China land cover dataset (CLCD), we provide a cropland abandonment and land reclamation mapping approach based on actual land use processes (rather than land cover conditions) to investigate spatiotemporal features of abandonment and reclamation and evaluate the rationality. Our findings show that: (1) Returning farmland to forest and grassland has been a clear trend in the study area over the past 30 years. Specifically, cropland use has undergone three phases of change, i.e., cropland contraction and expansion alternately (before 2000), followed by substantial abandonment (after 2000), and low-intensity reclamation (after 2010). (2) In the last decade, the intensity of the abandonment of cropland with high and moderate suitability is low. The rate of abandonment decreased, while the intensity of land reclamation was relatively high. The rate of the reclamation increased, and the spatial distribution of cropland tended to be reasonable. Our study emphasizes the importance of monitoring actual cropland changes based on land use processes, and this method can be effectively extended to regional or global long-term cropland monitoring.
