       Drought is a prolonged period of reduced precipitation that leads to water shortages, affecting agriculture, ecosystems, and human societies. It is driven by climatic factors such as changing weather patterns, increased temperatures, and reduced rainfall, often intensified by global climate change. Drought significantly impacts crop yield, soil moisture, and groundwater levels, leading to food insecurity and economic losses. It also disrupts ecosystems by reducing biodiversity and increasing the risk of wildfires and desertification. Effective drought mitigation strategies include sustainable water management, drought-resistant crop varieties, soil conservation techniques, and climate adaptation policies. Understanding the dynamics of drought and implementing proactive measures can help minimize its adverse effects on both natural and human systems.

Image analysis method combined with machine learning for the prediction of soil and air quality

-
      The integration of image analysis methods with machine learning has opened new frontiers in predicting soil and air quality with greater accuracy and efficiency. High-resolution satellite imagery, drone-captured visuals, and hyperspectral imaging are now widely used to extract visual features such as color variations, texture patterns, vegetation health, and land-use changes. These visual indicators are then fed into machine learning models—such as convolutional neural networks (CNNs) and support vector machines (SVMs)—to identify correlations with soil parameters (like moisture, pH, organic content) and air pollutants (like particulate matter, NOx, and CO₂). This data-driven approach enables continuous environmental monitoring, early warning systems, and sustainable land management strategies. The fusion of visual data with predictive analytics not only enhances spatial coverage but also minimizes the need for invasive sampling, offering a scalable solution for sm...

Study on soil pressure of loose soil in cohesive soil tunnel considering soil arch effect

-
  The study on soil pressure of loose soil in cohesive soil tunnels considering the soil arch effect focuses on understanding how stress is redistributed around underground openings. In mixed ground conditions, where loose soil is embedded within cohesive strata, the natural formation of soil arches significantly influences lateral and vertical load transfer. By analyzing how arch-shaped stress paths reduce the direct pressure on tunnel supports, researchers can better predict deformation, optimize lining design, and improve the safety of underground structures. The interaction between material properties, overburden depth, and tunnel geometry plays a crucial role in determining the extent and efficiency of the soil arch effect in mitigating soil pressure.

Carbon and Nitrogen in Mitigating and Adapting Agriculture to Climate Change

-
  Carbon and Nitrogen in Mitigating and Adapting Agriculture to Climate Change Carbon and nitrogen play pivotal roles in enhancing the resilience and sustainability of agricultural systems under climate change. Increasing soil organic carbon through practices like conservation tillage, cover cropping, and biochar application improves soil structure, water retention, and microbial activity, reducing greenhouse gas emissions while boosting crop productivity. Efficient nitrogen management—via precision fertilization, biological nitrogen fixation, and slow-release formulations—minimizes nitrous oxide emissions, a potent greenhouse gas, and enhances nutrient use efficiency. Integrating carbon sequestration and optimized nitrogen cycling supports climate-smart agriculture by improving soil health, increasing adaptive capacity to heat and drought stress, and sustaining long-term food security. These synergistic strategies not only mitigate climate change impacts but also enable farmers t...
