2024
Staphney Texina, Sathees Kumar Nataraj, Alagammai Renganathan and Kavitha Vasantha
This study focuses on assessing the toxicity levels in fruits and vegetables based on the presence of polycyclic aromatic hydrocarbons (PAHs), particularly in regions affected by industrial and vehicular pollution where the particulate matter deposits on the plant surfaces. Traditional methods, including Gas Chromatography/Mass Spectrometry (GC/MS) and HighPerformance Liquid Chromatography (HPLC), are used to measure PAH levels in fruits and vegetables, which are found to be valuable but expensive and time-consuming. However, the detection of toxicity relies on either expert knowledge or experimental analysis when compared with the limitations set by EFSA (European Food Safety Authority). Therefore, in this study, artificial intelligence techniques have been employed to evaluate the toxicity levels based on 16 PAHs. The PAH concentrations in fruits and vegetables were collected from different articles corresponding to safe and unsafe datasets and then validated through statistical analysis. The validated dataset is classified using different machine learning algorithms. Based on the output from the neural network, the level of toxicity is also scaled and compared with the targeted outputs. The promising results of the classification of toxicity using artificial intelligence methods are substantiated by an experimental study and validated through statistical methods. From the results, it can be observed that the machine learning algorithm has given classification accuracy of more than 90% along with their degree of harmfulness. This research holds implications for food safety and public health, offering a novel approach to the interdisciplinary understanding of climate change by addressing the impact of environmental contaminants on the edibility of fruits and vegetables.

The objective of this study is to provide a thorough assessment of soil erosion in the Hirshabelle state from 2020 to 2023, utilizing the Revised Universal Soil Loss Equation (RUSLE) and advanced geospatial technologies, particularly Google Earth Engine, to guide sustainable land management strategies. The study integrates multiple datasets, including CHIRPS for rainfall measurement, MODIS for land use analysis, and a digital elevation model for slope calculation, to offer a comprehensive understanding of the factors contributing to soil erosion. The rainfall erosivity (R) factor is calculated using CHIRPS data, while the soil erodibility (K-factor) is derived from the soil dataset. The topographic condition (LS-factor) is computed using the digital elevation model, and the cover-management (C) and support practice (P) factors are determined from the NDVI and land use data, respectively. The findings reveal considerable spatial variation in soil erosion across the Hirshabelle state. The results are categorized into five levels based on the severity of soil loss: very low (<5), low (5-10), moderate (10-20), high (20-40), and very high (≥40). While areas classified under “very low” soil loss are dominant, indicating relatively stable soils, regions under “very high” soil loss signal potential land degradation and the need for immediate intervention. Furthermore, the study revealed the intricate interplay of slope, vegetation, and land use in influencing soil erosion. Areas with steeper slopes and less vegetation were more susceptible to soil loss, emphasizing the need for targeted soil conservation measures in these regions. The land use factor played a crucial role, with certain land uses contributing more to soil erosion than others.

2024
Gajalakshmi G. and Meenakshi S.
Humans have evolved to the point where we are the most sophisticated animals in the world. The point of evolution is for creatures to become more suited to their natural habitat. A new degree of evolutionary adaption has been attained through humans. Massive technological advancements, new governments, and metropolises have all taken place. Every one of these societal advancements has one overarching goal: to ensure that our species continues to exist. As a species, we’ve figured out how to divide ourselves up into nations defined by shared values, religion, geography, and history. Divergences in geography, culture, and history have always been a source of contention among human beings. These disparities have, in the worst-case scenarios, led to war. Many various things, including religion and wealth, have sparked wars throughout history. War, though, never ends well; destruction is an inevitable byproduct. After a conflict, everyone is talking about how many lives were lost, how much property was destroyed, and how much money was spent. But the ecosystem is a quiet casualty of war. Seldom given a second thought are the deaths and devastation that befall Earth’s ecosystems, natural resources, and population. One can not help but question the impact of modern warfare on the environment and the consequences for humanity as a whole. The moral and social consequences of modern warfare’s assault on the environment can be seen by looking at the historical record of environmental degradation caused by this conflict. It is possible to learn about past and future efforts to safeguard the environment from human aggression by considering the problem from philosophical, scientific, and religious vantage points. If the Earth is to be further devastated by contemporary weaponry and combat, the loss endured by the environment will make the death toll of any contemporary battle appear negligible. The preservation of the natural world is crucial to the continuation of the human race.

Climate change, a critical global environmental crisis, profoundly impacts ecosystems, particularly in regions with delicate environmental balances. This study focuses on the Jhelum basin in the north-western Himalayas, examining the extensive effects of climate change on glaciers, snow cover, land use and land cover (LULC), land surface temperature (LST), water resources, and natural hazards. Rising temperatures have accelerated glacier melting and altered precipitation patterns, with significant implications for local water supplies and agriculture. The study analyses climate data from the Indian Meteorological Department (1990 to 2020), revealing increasing trends in both maximum and minimum temperatures, alongside variable precipitation trends across different locations. The retreat of glaciers and the expansion of glacial lakes have been observed, with lower-elevation glaciers showing the most significant reduction. LULC changes indicate a shift from agricultural land to settlements and horticulture, while LST has risen, particularly in urbanized areas, reflecting the impact of urbanization and climate change. Furthermore, the increased frequency of extreme weather events, such as floods and landslides, exacerbates the region’s vulnerability, threatening infrastructure, biodiversity, and local communities. The findings highlight the necessity of comprehensive, integrated approaches to address climate change and ensure the resilience of the Jhelum basin. This research contributes valuable insights into the region’s changing environmental dynamics, essential for informed decision-making and effective adaptation strategies in response to the ongoing climate crisis.

2024
A. Kishor Kumar, Govindaraju, C. J. Rakesh and S. Lokanath
For the past several decades, Tumkur has been one of the fastest-developing cities in Karnataka. Hence, an assessment concerning the identification of LULC mutations and their intensity and urban sprawl in Tumkur City has been employed using cutting-edge Geospatial techniques. In this study, multi-temporal satellite imagery such as Landsat 5 (2000), Resourcesat-1 (2005, 2009 & 2012), and Sentinel-2A (2015 & 2020) were utilized to monitor historical LULC changes, land transformation, direction of urban growth and sprawl. The outcome of the change detection demonstrates that between 2000 and 2020, the built-up area expanded significantly, from 24.94 km2 to 60.59 km2. Consequently, the land transformation matrix analysis shows that substantial modifications in LULC have occurred over the period, with a rise in built-up areas and plantations and a decline in agricultural land, water bodies, and scrubland. Further, urban expansion analysis using UEII (Urban Expansion Intensity Index) revealed that most of the area is in the fast-paced stage of urban expansion. Moreover, two well-known indices; the Annual Urban Spatial Expansion Index (AUSEI) and the Annual Built-up Change Index (ABCI), show a significant positive correlation between them (R2 = 0.69) justifying the increased urban growth in the study area. Whereas, built-up density and the Annual Urban Spatial Expansion Index (AUSEI) show a negative correlation (R2 = 0.55) indicating the presence of compactness of the core of the city. Apart from the above analysis, urban sprawl was effectively interpreted using zones formed using Shannon entropy; NNE, ESE, and SSW have high urban sprawl due to National Highways, growth of Industries, and infrastructure activities developed by the government. Further, the present study’s findings will contribute to understanding land use dynamics, urban sprawl, urban growth analysis, and future projections, as well as provide crucial information for decision-making and urban planning processes, to the urban planner to support acceptable land use management and guiding plan for appropriate growth of urban areas.

The degradation of atrazine (ATZ) was studied in the presence of β-cyclodextrin (β-CD) under ultraviolet light irradiation. The β-CD was characterized by modern analytical techniques and the different operating parameters of photodegradation were investigated. Experimental results revealed irregular shapes in the structure of β-CD, and the functional groups of β-CD were present in the glucose units. The BET surface area of β-CD was 285.02 m2/g with a pore volume of 0.172 cc/g and a pore diameter of 2.138 nm, whereas, the x-ray diffraction analysis revealed the polycrystalline nature of β-CD. The z-average diameter of the particle size distribution was determined as 63.21 nm, thermogravimetric analysis data demonstrated weight loss events while the differential thermal analysis data revealed associated energy changes during phase transitions. The photodegradation of ATZ in the presence of β-CD resulted in 80.80% and 59.40% degradation, respectively, for 6.25 mg/L and 100 mg/L of ATZ after 60 min of irradiation time. The treatment method could be described by the Langmuir-Hinshelwood kinetic model, with kc equals 0.1462 mgL-1min-1 and KLH equals 10.45 × 10-2 Lmg-1. Thus, photodegradation with β-CD as a catalyst could be effectively used for the remediation of pesticide-contaminated wastewater.
