      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...

       Fragmented forests play a critical role in sustaining herbivore assemblages within agroecosystems by acting as vital habitat patches that offer food, shelter, and movement corridors for various herbivorous species. Despite being broken into smaller units due to agricultural expansion, these forest fragments can still support biodiversity by maintaining ecological niches and reducing the impacts of habitat isolation. Herbivores, ranging from small rodents to larger ungulates, often depend on these fragmented areas for refuge and seasonal resources, especially in landscapes dominated by crops or pastures. Additionally, the presence of a diverse herbivore community contributes to ecosystem services such as seed dispersal and nutrient cycling, enhancing the resilience and productivity of the agroecosystem. Maintaining and managing forest fragments can thus be a strategic component in sustainable agricultural practices, promoting both biodiversity conservation and...

  The synergistic interactions of CO₂ fertilization with water availability, heat stress, and nitrogen levels are critical to understanding crop productivity under climate change. In major staples like maize, rice, and wheat, elevated CO₂ often enhances photosynthesis and yield—a phenomenon known as CO₂ fertilization. However, this benefit is not uniform and can be significantly altered by water scarcity, extreme temperatures, and nutrient limitations. For instance, while CO₂ enrichment may increase biomass, water stress can offset these gains by limiting transpiration and nutrient uptake. Similarly, heatwaves during sensitive growth stages like flowering can negate CO₂ benefits through spikelet sterility or kernel abortion. Moreover, the positive response to CO₂ is amplified only when nitrogen is sufficiently available, indicating a complex interplay among these factors. Recent field experiments and modeling studies demonstrate that without simultaneous improvements in water and ...

       A sustainable organic waste biorefinery model plays a vital role in achieving energy development goals for agriculture-based economies.

This approach supports multiple Sustainable Development Goals (SDGs), including affordable and clean energy (SDG 7), sustainable cities and communities (SDG 11), responsible consumption and production (SDG 12), and climate action (SDG 13). The integration of biorefineries into rural agricultural systems enhances energy security, reduces dependence on fossil fuels, and boosts local employment through green jobs. Furthermore, the nutrient-rich byproducts from the biorefinery process can be reused as biofertilizers, fostering soil health and promoting sustainable agriculture. Overall, this model offers a scalable, eco-friendly solution to energy...

  The fluid-solid coupling large deformation failure analysis of bucket foundations in saturated clay is a critical study that integrates the interaction between soil and pore water pressure under extreme loading conditions. Bucket foundations, widely used in offshore engineering, experience complex deformation behavior when embedded in saturated clay due to the undrained response of the soil. By employing advanced numerical methods such as the coupled finite element method, researchers can simulate the progressive failure mechanisms, including soil flow, bearing capacity loss, and excessive tilting or penetration. This approach enables the prediction of deformation patterns and failure zones more accurately under various operational scenarios, improving the design safety and resilience of offshore structures subjected to cyclic and monotonic loads.

       Suitability analysis of crops for sloping farmland in arid sandy regions using traditional farming methods is essential for sustainable agricultural development in fragile ecosystems. These regions often face challenges such as low water retention, high erosion risk, and nutrient-poor soils. Traditional farming practices, when adapted to local conditions, can offer valuable insights into crop selection and land management. Crops like millet, sorghum, legumes, and drought-tolerant vegetables have shown resilience and adaptability in sloped terrains due to their deep root systems and minimal water requirements. Additionally, intercropping and terracing—key components of indigenous knowledge—help conserve moisture and reduce erosion. By aligning crop choices with land characteristics and leveraging traditional knowledge, farmers can improve productivity and ecological balance while preserving soil health in arid sandy landscapes. #SlopingFarmland #AridRegionsAgr...

       A comparative sustainability investigation between a novel industrial-waste-based soil stabilizer and traditional cement has been conducted using Life Cycle Assessment (LCA) methodology. The study evaluates the environmental impacts associated with each stabilizing material from cradle to grave—including raw material extraction, production processes, transportation, application, and end-of-life scenarios. Results show that the industrial-waste-based stabilizer significantly reduces greenhouse gas emissions, energy consumption, and resource depletion compared to conventional cement. This eco-innovative solution not only diverts industrial by-products from landfills but also offers a low-carbon alternative in geotechnical and construction applications. The findings underscore the potential of circular economy strategies in soil stabilization while promoting environmentally conscious infrastructure development. #SustainableConstruction #SoilStabilization #LifeCy...

        Disturbance from tillage plays a critical role in shaping soil biodiversity across different grassland management types. In a comparative study of three grassland systems—conventionally tilled, minimally disturbed, and undisturbed—soil biodiversity patterns were most strongly influenced by the intensity and frequency of tillage. Tillage disrupts soil structure, alters microhabitats, and affects moisture and nutrient dynamics, which in turn can reduce microbial diversity and abundance. In contrast, minimally disturbed and undisturbed systems tend to support richer and more stable soil communities due to preserved organic matter and favorable micro-environments. Thus, tillage-induced disturbance emerges as a dominant driver of variation in belowground biodiversity among grassland ecosystems.

       Developing a strong topsoil structure through effective conservation management is essential for safeguarding subsoil from compaction. Topsoil acts as a protective buffer, absorbing pressure from machinery and livestock, and dispersing it more evenly. Conservation practices such as cover cropping, reduced tillage, organic matter addition, and controlled traffic farming significantly enhance soil aggregation and porosity. These methods improve water infiltration and root penetration while minimizing direct stress on the subsoil layers. By maintaining a resilient and well-structured topsoil, land managers can prevent long-term damage to subsoil, preserve soil health, and ensure sustainable agricultural productivity.

       Land use change significantly influences plant diversity and soil carbon (C) and nitrogen (N) stocks in semi-arid grasslands. Converting natural grasslands to croplands or grazing areas often leads to a reduction in plant species richness, altering ecosystem stability and resilience. Intensive land use practices can deplete soil organic carbon and nitrogen, thereby diminishing soil fertility and long-term productivity. Conversely, sustainable land management and restoration efforts can help preserve biodiversity and enhance C/N storage by promoting native vegetation and improving soil structure. Understanding these interactions is essential for balancing agricultural productivity with ecosystem conservation in fragile semi-arid environments. #LandUseChange #SemiAridGrasslands #PlantDiversity #SoilCarbon #SoilNitrogen #BiodiversityLoss #EcosystemRestoration #SustainableLandManagement #GrasslandEcology #SoilHealth #CarbonSequestration #ClimateSmartAgriculture V...

        Legume-based crop rotation is a sustainable agricultural practice that significantly enhances soil phosphorus (P) availability and boosts the productivity of subsequent crops. Legumes, through their symbiotic relationship with nitrogen-fixing bacteria, improve soil health and promote microbial activity that aids in phosphorus solubilization. Additionally, legume root systems release organic acids and enzymes that help mobilize phosphorus bound in soil particles, making it more accessible to plants. This improved nutrient availability translates into higher yields and better crop performance in the following growing seasons. By integrating legumes into crop rotations, farmers can reduce dependence on synthetic fertilizers, improve soil fertility, and ensure long-term agricultural sustainability.
