Summary: Cropland area and cropping frequency are crucial for regional food production. Urbanization and declining agricultural labor force have changed land use and cropping patterns. Using satellite data, this study found a decrease in cropland area but a stable double-cropping area in the North China Plain. Winter wheat and summer maize rotation showed a significant increase, likely due to land-use and grain subsidy policies.

Summary: This study examined the characteristics of crop planting structure and changes in crop production, focusing on the self-sufficiency rates of wheat and maize in Ningjin County, North China Plain. The results showed an increasing trend in the sown area and self-sufficiency rates of both crops, indicating a safe state of grain yield. The study also identified the limits of fertilizer use in increasing crop yield.

Summary: This paper analyzes the differentiation in the spatial distribution of arable land and the development of crop production in EU member states. The results show no clear changes in crop production across the EU, but new member states entering the EU after 2004 show higher dynamics. Additionally, significant regional geographical differences reflecting different natural conditions and historical social development were found among EU states.

Summary: Irrigation has the potential to alter surface characteristics and local climate. Satellite observations have shown that irrigation leads to cooling of air and land surface temperatures, decreased precipitation, and increased vegetation growth and evapotranspiration. The findings of this study highlight the significant impact of irrigation on temperature, vegetation, and climate, providing valuable information for predicting future climate change.

Summary: This study presents an iterative approximation strategy to address the underdetermined problem in the linear spectral mixing model. By selecting mixed pixels with similar land covers in the neighborhood to form the unmixing linear system, the proposed algorithm effectively solves the underdetermined problem for mixed pixels of different scales.

Summary: This study utilizes high-resolution ERA5 hourly data and long-term normalized difference vegetation index (NDVI) time series to analyze the spatiotemporal characteristics of extreme rainfall in the Huang-Huai-Hai Plain. The study finds a decreasing trend in extreme daily precipitation but an increasing trend in the proportion and intensity of extreme rainfall. The spatial distribution of extreme rainfall follows China's rain belts, with the Huaihe River region and the Shandong Peninsula being high-incidence areas. The study also highlights the increasing risk of flooding due to extreme hourly precipitation events in some areas of the Plain.

Summary: Soil quality is crucial for agricultural productivity, farm resilience, and environmental quality. Sustainable soil management may involve short-term financial sacrifices but leads to long-term benefits. Understanding soil quality and integrating it with production management is essential for maximizing the Economic Value of Land.

Summary: This study modeled the vegetation health index (VHI) of rabi crop and examined its time series change from 1990 to 2019 using Landsat satellite images. The results showed a significant change in crop health over the past 30 years, with a larger area of rabi crop in poor health in the present decade. The study highlights the importance of monitoring and managing crop health for sustainable agriculture.

Summary: This study examined the trends and spatial distributions of cotton evapotranspiration and irrigation requirements in the North China Plain using historical climate data. The results showed a significant decrease in cotton evapotranspiration over the past five decades, with changes in effective rainfall and irrigation demands. Irrigation contributed 25% of cotton evapotranspiration, highlighting the impact of climate change on water requirements for cotton irrigation scheduling.

Summary: This study investigates the effects of climate change and cropland management on crop growth and evapotranspiration in the North China Plain. By combining an agrohydrological model with 16 years of observation, the study found that advanced sowing date and rising temperature were the main causes of early start and end of the growing season. However, the advanced sowing date significantly shortened the growing season length. Increasing temperature negatively affected leaf area index and crop yield, while slightly promoted by elevated CO2 concentration. Maize's growth was greatly improved by increasing radiation and irrigation, while excessive irrigation hampered wheat's growth. The study also suggests that the increase in wheat's growth attributes to the renewal of cultivars.

Summary: Crop simulation models, particularly the AquaCrop model, were used to simulate grain yield and biomass for 11 cultivars in the study. Results showed high simulation accuracy under full irrigation but lower accuracy under water-saving irrigation for both winter wheat and summer maize. The model is reliable for simulating crop growth in the NCP region, but limitations should be considered when simulating winter wheat under water-stressed conditions.

Summary: The study reveals that there is a significant growth trend in vegetation NDVI in Ordos City, with autumn experiencing the fastest growth rate. However, without effective measures, future vegetation NDVI may degrade. Precipitation is the main climate factor influencing vegetation growth, while increasing temperatures have a negative impact by reducing precipitation throughout the growing season. Additionally, land use patterns greatly affect the spatial distribution of vegetation NDVI.
