Summary: The expansion of the urban-rural fringe has had a severe impact on soil quality, particularly valuable arable land resources. This study compared the soil quality of reclaimed land in the URF to nearby grain fields, open-air vegetable plots, and facility vegetable plots. The results showed that the reclaimed land had lower soil quality and needed proper fertilization for improvement.

Summary: This study mines and analyzes the word frequency and occurrence position of industrial policy keywords, determines the main policy parameters affecting industrial development, and establishes a functional relationship between industrial policy and industrial development through multi-parameter non-linear regression. The study concludes that there is a certain coupling effect between different policies, and industrial development is influenced by the joint effect on the parent and sub-industries, ultimately demonstrating a clear correlation between policy and industry development.

Summary: This study investigated the effects of urbanization and land-use intensity on antibiotic contamination in soil and found that urbanization level plays a crucial role in determining the concentration and seasonality of antibiotics. Furthermore, the interactions between urbanization and land-use explained a large portion of the variation in antibiotic concentrations across urbanization gradients.

Summary: Biochar, bio-oil, and synthesis gas obtained from the pyrolysis process were modeled using artificial neural networks and hybrid models. The study identified the most effective factors for the production of biochar, bio-oil, and synthesis gas, with gas flow rate being crucial for biochar and bio-oil, and holding time for synthesis gas.

Summary: Overparameterization in deep learning shows a double-descent behavior, where the risk can grow arbitrarily when the number of parameters approaches the number of samples, but decreases with more parameters. This study demonstrates that for certain data models, the risk divergence caused by overparameterization can be avoided by using principal component analysis-based dimensionality reduction. The researchers compare PCA-OLS with other projection-based methods and find that methods dependent on training data perform better.

Summary: Rural-urban migration is widespread in Bangladesh, especially among farmers. This study aimed to identify the factors influencing farmers' decision to move from rural to urban areas. The findings suggest that individual, household, economic, attitudinal, spatial, and climate-induced variables significantly influence farmers' rural-urban migration decisions.

Summary: In this study, digital soil assessment using principal component analysis and multiple linear regression was conducted to create a digital map of soil fertility for jasmine rice. The map revealed that over half of the Thung Kula Ronghai region had low to very low soil fertility levels, which corresponded well with actual rice production in the area.

Summary: A new genomic prediction method, RHPP, was developed by combining randomized Haseman-Elston regression (RHE-reg), PCR based on genomic information of core population, and preconditioned conjugate gradient (PCG) algorithm. The study showed that RHPP had similar prediction accuracy to GBLUP, and significantly higher computational efficiency as the number of individuals increased. Real datasets of bread wheat and loblolly pine also demonstrated that RHPP had similar or better predictive accuracy compared to GBLUP. In the future, RHPP may be a promising choice for analyzing large-scale and high-dimensional data.

Summary: This study explores the relationship between petrochemical contaminated areas and natural, socio-economic, and traffic factors. The MaxEnt model is used to identify potentially contaminated areas. The results show that areas with high probability of contamination are mainly distributed in economically developed cities with dense populations and convenient transportation.

Summary: Small farms are gaining recognition in agricultural policies in the European Union, as they play a significant role in preserving the landscape and fostering local rural economic development. This study focused on defining the characteristics of small farms and analyzing their economic and financial situation using Italian FADN data. The research found that small farms in Italy are mainly specialized in arable land and herbivores, predominantly managed by male farmers with a high school education. While economic performance is generally good, there is regional disparity, with Southern farms relying more heavily on public support. The study's findings provide valuable insights for stakeholders in designing and implementing specific measures to support the survival of small farms in rural areas.

Summary: This case study focuses on the meticulous observation of urban soil pollution by heavy metals (HMs) or potentially toxic elements (PTEs) in the urban center of Volos, Greece. The study found an increasing trend of metal concentration over the past four years. Statistical analysis and principal component analysis (PCA) revealed correlations between different HMs and significant changes in metal concentrations were observed in different parts of the city during the COVID-19 pandemic. Further research is needed to identify pollution sources and find ways to reduce it.

Summary: A new method combining various techniques was proposed to evaluate the suitability of urban development land, improving the accuracy and objectivity of the evaluation results. The method can avoid subjective influences and provide highly accurate evaluations, potentially serving as a scientific reference for land resource allocation in urban development.

Summary: The distribution of heavy metal concentrations and related human health risks were investigated in Shimabara City, Nagasaki Prefecture. Potential heavy metal contamination in an area affected by nitrate pollution was clarified, with livestock waste application and other anthropogenic pollutants identified as the possible sources. High concentrations of Cu and Zn were found in agricultural areas and urban areas.
