Summary: The present study uses a high-resolution model to simulate the meteorological conditions before and after the Chamoli rock-ice avalanche event in India on February 7, 2021. The simulation results show significant departures from the usual patterns of meteorological variables few hours and 72 hours before the event. The air and surface temperatures near the avalanche site were lower before the event, and the total turbulent heat flux was exceptionally negative. Rainfall data also suggest significant rainfall in the Himalayan region prior to the event 48 hours earlier.

Summary: The Indian Himalayan region has been experiencing frequent hazards and disasters associated with permafrost. However, there has been little or no research on permafrost in this region. It is important to have knowledge about the spatial distribution and state of permafrost in the Indian Himalayas. This study used modern remote sensing techniques and a geographic information system (GIS) to assess permafrost in the Alaknanda Valley of the Chamoli district in Uttarakhand state. The results showed that a logistic regression model based on mean annual air temperature produced the most accurate predictions of permafrost distribution.

Summary: This study investigated the potential of different cyanobacterial and microalgal strains for biodiesel feedstock production. The ranking of strains was performed using the PROMETHEE software, considering specific growth rate, biomass productivity, and lipid content as important parameters. The study identified Pseudobohlinia sp. and Leptolyngbya foveolarum as the most promising candidates for biodiesel production, with several other strains also showing high potential.

Summary: A Cloud Condensation Nuclei Counter was deployed in the pristine Himalayan region for the first time to measure CCN concentrations. The study revealed significant variations in CCN concentrations under different weather conditions, possibly influenced by factors such as air mass transport, convection process, anthropogenic emissions, and biomass burning.

Summary: There has been a recent resurgence of interest in hydrocarbon exploration in the Lesser Himalayan Sequence (LHS) among petroleum geoscientists. Understanding the paleostress regime and deformation mechanism are critical for understanding the structural geology of petroleum-bearing terrains. Arc-parallel shear is an important deformation process in orogeny, and its scale can vary from micro-mm to regional-scale. This study reviews the mechanisms and theories of arc-parallel shear in several orogens, including the Himalaya, and compiles a list of 44 worldwide locations with arc-parallel shear. The Himalayan mountain chain has been formed by continuous crustal shortening due to the collision between India and Eurasia, and the rock mass also experiences lateral escape along the orogenic trend. The flow of the rock mass is governed by the tectonic stress field. Field study and microstructural analysis in the northwest LHS in India reveal the occurrence of arc-parallel brittle and ductile shear movements, with different shear directions and origins related to stretching and shortening. The findings provide insights into the tectonic evolution of the Himalaya and have implications for hydrocarbon exploration in the region.

Summary: This research assesses the groundwater quality in the Dehradun Valley of Uttarakhand, India, using geographical information system and multivariate statistical tools. The study found that the groundwater in the area is dominated by calcium-magnesium-bicarbonate hydro-chemical facies, influenced by the presence of limestone, dolomite, magnesite, and talc rock types. Some water sources showed signs of anthropogenic pollution and were deemed unfit for consumption. The study also discovered higher turbidity and iron concentration in certain sources, exceeding drinking water specifications.

Summary: This study documented 110 important ethnomedicinal plants from the Maraog region in Himachal Pradesh, India, with most species belonging to the Rosaceae and Asteraceae families. Leaves were found to be the most commonly used part in preparing herbal medications. Elderly individuals showed a deep knowledge of wild medicinal plants, while younger generations lacked knowledge in this area.

Summary: This study reviews the current status and causes of land subsidence in Joshimath town, Uttarakhand, India. The town is located in a geologically unstable area, close to major fault lines, and has experienced population growth, leading to ongoing slope instability and land subsidence. The results of this study are important for scientific monitoring and mitigation of land subsidence.

Summary: Springs are crucial for Himalayan communities, and it is important to protect and conserve these traditional water sources. A study conducted in the Alaknanda Valley, Uttarakhand, reveals that highly tectonically disturbed zones have greater variation in isotopic composition of spring water compared to less disturbed zones. This study emphasizes the need for conservation strategies in these highly active thrust zones.

Summary: This study explores the practices of herbal management of malaria among trading mothers in Shai Osudoku District, Accra. It reveals that, despite the existence of several orthodox medications for treating malaria effectively, many individuals in developing countries still turn to herbal medicine. The study finds that individual preferences for malaria treatment are influenced by factors such as cultural beliefs and the effectiveness of herbal medicine. The main challenge identified is the lack of appropriate dosage specifications for herbal malaria treatment.
