Furthermore, combining crop switching with improved agricultural management practices can further reduce soil erosion in cropland by an estimated 25 %. Cereals including maize, wheat, and rice demonstrate significant potential for reducing soil erosion in cropland. Shifting major maize-producing areas northward could result in a substantial decrease in soil erosion, ranging from 10 % to 19 % of historical soil erosion in cropland.

In this framework, the NSGA-II algorithm was used to construct the multi-objective optimization model of crop planting structures with consideration of water and energy consumption, greenhouse gas (GHG) emissions, economic benefits, as well as food, land, and water security constraints, while the model for planting spatial layout optimization was established with consideration of crop suitability using the MaxEnt model and the improved Hungarian algorithm. This framework was further applied in the Black Soil Region of Northeast China (BSRNC) for analyzing optimized crop planting structures and spatial layouts of three main crops (rice, maize, and soybean) under various scenarios. This study showed that the sown area of rice in the BSRNC decreased by up to 40.73 % and 35.30 % in the environmental priority scenario and economic-environmental balance scenario, respectively, whereas that of soybean increased by up to 112.44 % and 63.31 %, respectively. In the economic priority scenario, the sown area of rice increased by up to 93.98 %. Expanding the sown area of soybean was effective in reducing GHG emissions. On the contrary, rice production led to greater environmental costs though it provided higher economic returns. Among the three crops, maize exhibited an advantage in balancing environmental and economic benefits. Hegang-Jixi area in the northeast of the BSRNC was identified as the key area with the most intense crop planting transfer among different scenarios. Overall, this framework provides a new methodology for optimizing crop planting structures and spatial layouts with consideration of the nexus of various factors.

Within the SES, combined scenario analyses further suggest that the rocky desertification rate and the urban-rural income ratio exhibit the least trade-off potential and intensity in combined economic priority scenario and ecological protection scenario, and the Soil Conservation and Food Supply demonstrate the least trade-off potential and intensity in combined economic priority scenario and food security scenario.
