Summary: The demand for rice in Taiwan has decreased while the demand for wheat and maize has increased due to changes in dietary habits. The crop suitability of rice, wheat, and maize in Taiwan was evaluated using multi-criteria assessment, hierarchical analysis, and sensitivity analysis methods. The results showed that rice has moderate to high suitability all over Taiwan, especially in southwestern Taiwan. Wheat is more suitable in hill areas of central, northwestern, and southeastern Taiwan. Many agricultural lands in Taiwan are suitable for maize except for coastal areas in the western plains. The study suggests the potential for expanding the cultivation areas for wheat and maize based on agroecological conditions.

Summary: Intensive crop growth can cool temperatures and dampen anthropogenic warming over breadbasket regions. However, climate models overestimate temperatures and underestimate evapotranspiration over global croplands, indicating the need for improved representations of crop-climate processes in future projections over these vulnerable regions.

Summary: Reconstructing historical land use and land cover change is crucial for understanding climate change, ecological effects, and anthropogenic land use alterations. In this study, a provincial cropland area dataset for China over the past millennium was created, and land suitability for cultivation was assessed. The results showed that the cropland area in China increased from AD 1000 to AD 1999, with fluctuating increasing trends divided into three phases.

Summary: Climate change is impacting global crop productivity and agricultural land suitability, leading to changes in land use and potentially significant environmental and socioeconomic effects. This study analyzes the correspondence between changes in cropland and climate variables, revealing that higher temperatures and increased drought severity are associated with greater cropland loss. These patterns vary across regions and countries due to different socioeconomic factors and adaptation strategies. This global-scale analysis complements regional studies and provides context for locally-observed phenomena.

Summary: Efficient and targeted use of phosphorus is crucial in avoiding environmental issues caused by population growth and increased food demand. Global projections indicate a significant amount of new arable land will be needed by 2050, but with proper phosphorus management, cropland expansion can be avoided while improving productivity levels.

Summary: Spatially explicit historical land cover datasets are crucial for various simulations and projections. This study collected and analyzed cropland area data in Scandinavia from 1690 to 1999, revealing changes in cropland area over time. Comparisons with global datasets showed some agreement in total cropland area, but significant differences in spatial patterns were observed, highlighting the importance of regional datasets for accurate analyses.

Summary: The increasing demand for calories and protein, alongside urbanization, presents significant challenges to China's food security. This study examines the impact of temperature on land use in China using high-resolution satellite data and daily weather data from 1980 to 2010. The findings suggest that extremely hot weather has a long-lasting effect on reducing cropland in China, and climate change is predicted to further decrease China's cropland area by the end of this century.

Summary: Monitoring multifunctional agricultural areas is crucial for effective management. This paper presents a Python application for monitoring LCLU changes in these areas based on the RaoQ diversity index. The workflow involves data processing, NDVI calculation, RaoQ calculation, and detection and mapping of LCLU changes. Three methodological approaches were developed and achieved high overall accuracies. An example of agri-environmental monitoring decision-support framework is also provided.

Summary: Lake Marmara, located in Western Turkey, is an environmentally degraded water resource, but officially recognized as a priority wetland due to its historical habitats and ecosystem functions. Land use/cover changes (LULCC) and climate change pose significant threats to the region, impacting local communities' access to fundamental ecosystem services.

Summary: Global cropland area is increasing, with significant expansion in regions like Eastern Asia, Southern Asia, Eastern Europe, Southern America, and Northern America. The expansion of new croplands has negative impact on Net Primary Productivity and Evapotranspiration, especially in Southern America. While new croplands in Asia and North America improve agricultural productivity, they also lead to increased water resource consumption.

Summary: In this study, future agricultural land-use changes were assessed under different scenarios, and the spatial patterns were analyzed. The results showed varying changes in cropland area under different scenarios, with the presence of geographic hotspots and coldspots. These findings are crucial for land management and understanding the impacts of cropland under different scenarios.

Summary: Land management practices, such as cover crop cultivation, can mitigate the environmental impact of agriculture, improve productivity, and help sequester carbon. This study assessed the impacts of cover crop practices on sustainable land use and found positive effects on soil carbon and nitrogen dynamics, as well as on soybean yield.

Summary: This study estimated the global biophysical temperature effects of LULCC using CMIP6 climate models and found a historical global warming effect of LULCC at a rate of 0.0025 degrees C/century. Forested/non-forested secondary land, urban land, and cropland have contributed over 70% to LULCC's temperature effect, with land transitions and land management also playing significant roles in the climate impact.

Summary: This study predicts a decreasing trend in future cropland N2O emissions in China using high-precision land use data, with a reduction in total emissions and cropland area. However, some cities in China are projected to emit more than current levels, and different land use and climate change scenarios will have significant impacts on cropland N2O emissions. The implementation of environmental projects, like the Grain for Green Plan, could effectively control emissions by about 12%.

Summary: This study estimated the change in irrigation water use (IWU) caused by cropland spatial shift in China using the CROPWAT model and multi-source data. The results showed that the movement of cropland centroid towards the northwest led to an increase in national IWU, particularly in the northwest region. The study suggests that priority should be given to increasing crop yield and decreasing IWU per unit area on existing croplands in the northwest, rather than reclaiming new cropland.
