This paper examines the factors that affect human–wildlife conflict and its socio-ecological consequences, including impacts on the daily lives of rural people, farming activities, children’s schooling, and livestock rearing. Both qualitative and quantitative approaches were employed. Data were collected from secondary sources, primarily the Uttarakhand State Forest Department and the Forest Survey of India, covering 25 years (2000–2025). Information on wildlife species, their populations, and the number of people killed or injured by wildlife was obtained. The author visited some affected areas of human–wildlife conflict in July 2024 and January 2025. A perception study was conducted in which 212 people from five villages were interviewed. A map of human–wildlife conflict hotspots was also prepared. Three districts of Uttarakhand—Pauri, Almora, and Tehri—were identified as human-wildlife conflict hotspots. This study reveals that elephants dominate the plains—namely the Doon Valley and the Tarai region—whereas leopards and bears dominate the middle Himalayan region in terms of human–wildlife conflict. Wild boars and langurs are also found in the same region. Snow leopards are confined to the Greater Himalayan region. Every day, one or more people are killed by wildlife, and the number of injured people is considerably high. Fatalities from leopard attacks are highest, followed by bear attacks, mainly in the middle Himalayan region. The study suggests that both the Forest Department and local communities can play significant roles in managing wildlife through awareness programmes and improved forest management.
Multilayer composite materials are used in advanced engineering as a material for heavy-duty products. However, the use of multilayer composite materials requires consideration of their inherent specific properties, such as anisotropy of mechanical characteristics and the possibility of the presence of hidden defects in the form of discontinuity of the material along the interfaces of individual layers (laminations). Evaluation of interlayer failures throughout the life cycle is critical to reducing composite product safety risks. In this article, the analysis of interlayer defects in composites employs comprehensive control, including several non-destructive testing methods: visual inspection, ultrasonic flaw detection, active thermography, and numerical modeling. Interlayer defects obtained as a result of low and high-speed impact on multilayer composite materials are considered. It has been found that the results from numerical modulation of interlayer defects and from non-destructive inspection of defects such as laminations, obtained by different methods, agree satisfactorily.
Glyphosate is one of the most extensively used organophosphorus herbicides; however, its excessive application and environmental residues have severely threatened aquatic ecosystems and human health. In this study, a highly efficient lanthanum-modified zeolite (LMZ) adsorbent was synthesized via a hydrothermal method, and its adsorption behaviors and underlying mechanisms for glyphosate removal were systematically investigated. LMZ exhibited exceptional adsorption performance over a broad pH range of 3.0–7.0, achieving a maximum adsorption capacity of 217.39 mg/g. The adsorption process was well described by the Langmuir isotherm and pseudo-second-order kinetic models, indicating a monolayer chemisorption process. Notably, LMZ demonstrated remarkable adsorption selectivity and excellent regenerability, maintaining a high adsorption capacity even after five consecutive adsorption-desorption cycles. In practical application assessments with simulated wastewater, glyphosate removal efficiency exceeded 90% at an adsorbent dosage of 7.5 g/L. Furthermore, dynamic column experiments confirmed that LMZ could maintain effective continuous adsorption, highlighting its substantial application potential for treating glyphosate-contaminated wastewater. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopic characterizations revealed that this outstanding adsorption capability is primarily driven by inner-sphere complexation induced by ligand exchange at the La-OH active sites.
The Sahel is a strip of land that begins in Mauritania and ends in Eritrea. It is approximately 5400 km long and varies in width from 100 to 1000 km. Based on different historical perspectives, the Sahel can be considered to encompass a total of five countries. Subsequently, other countries have been added that, due to their geographical and climatic characteristics, can be considered Sahelian. The Sahelian countries emerged after 1960, the year in which decolonization began, but also the instability that was initially triggered by military coups aimed at destabilizing power. Later, climatic instability, famine, political instability, terrorism, and other factors have also played a role. This essay focuses on analyzing the actions and current activities of certain actors in the Sahel.
