Identification of Major Threats of Climate Change, Hazards, and Anthropogenic Activities on Biodiversity Conservation in the Buxa Tiger Reserve, India.

The Himalayan forests are facing a range of threats, which are making conservation efforts challenging. Using a mixed-method approach, this study investigated the threats to biodiversity conservation in Buxa Tiger Reserve (BTR), a fragile ecosystem in the Eastern Himalayan foothills. The study found that between 1990 and 2021, BTR experienced rising summer temperatures and decreasing annual precipitation, contributing to forest dryness, water scarcity, and forest fires. Natural disasters such as floods, flash floods, earthquakes, and landslides also caused significant damage to wildlife habitats. Changes in land use and land cover, including encroachment, infrastructure development, fuelwood collection, and grazing practices, were also identified as significant drivers of ecosystem alteration. Besides, hunting and poaching also emerged as threats to wildlife populations in the reserve. By employing the Analytic Hierarchy Process (AHP), the study determined that land use change, infrastructure development, climate change, livestock grazing, and fuelwood collection pose significant threats to flora conservation outcomes in BTR, while infrastructure development, climate change, livestock grazing, and forest fires are the primary threats to wildlife conservation outcomes in the reserve. The study recommends the regulation of land use practices, promotion of sustainable livelihoods for local communities, effective conservation strategies, and public awareness and education programs to promote the value of biodiversity conservation.

Factors Influencing the Feasibility, Effectiveness, and Sustainability of Farmers' Adaptation Strategies to Climate Change in The Indian Eastern Himalayan Foothills.

The rapidly changing climatic conditions are adversely impacting the Indian agricultural sector. Farmers are frequently seen adopting several adaptation measures, which are neither equally efficient nor mutually exclusive. Based on the primary data collected from 300 farming households of the Indian Eastern Himalayan foothills, the present study attempts to examine the efficiency of local farmers' adaptation by developing indices combining the feasibility, effectiveness, and sustainability of the adaptation measures with the scale of actual adoption. Further, by employing multiple linear regression, the study analyzes the internal (psychological) and external (physical and socio-economic) factors influencing higher scores of these indices. Results show that local farmers are well aware of climate change and are responding through implementing at least one and up to seven adaptation measures. Farmers preferred agroforestry, a shift from cereals to low water-intensive commercials, irrigation, and intensification of winter crops as the most efficient. There was, however, a misalignment between the perceived efficiency of adaptation measures and their scale of adoption. Farmers' perceptions of pest infestation, satisfaction with farming, soil characteristics, farm size, remittances, and access to credit were found to be positively and significantly influencing the adaptation indices, while open-mindedness toward changing farming practices and crop-raiding by elephants were found to be negatively and significantly associated with adaptation indices. Lastly, the study made relevant recommendations for improving farmers' efficiency in adopting appropriate adaptation measures and strengthening the "State Action Plan on Climate Change".

An evaluation of liver function tests in severe acute respiratory syndrome - Corona virus 2 (SARS-CoV-2) infection in the backdrop of chronic kidney disease.

Background: The SARS-CoV-2 pandemic has emerged as the most challenging global health problem of this century. The concomitant presence of co-morbidities like chronic kidney disease (CKD), diabetes, CHD, further complicates the problem. Aim: To assess the patterns of LFT abnormalities in patients of SARS-CoV-2 infection with and without CKD and evaluate the probable outcomes. Materials and Methods: A cross-sectional retrospective observational study done on 600 patient samples (Group 1: SARS-CoV-2 without CKD, Group 2: SARS-CoV-2 with CKD and Group 3: CKD uninfected with SARS-CoV-2) which were processed for LFT and KFT. Results: AST and ALT were significantly higher in all SARS-CoV-2 infected; Group 1 mean ± 2SD, (63.63 ± 42.89U/L & 50.25 ± 46.53U/L), group 2 (90.59 ± 62.51U/L & 72.09 ± 67.24 U/L) as compared to Group 3 (25.24 ± 7.47U/L & 24.93 ± 11.44U/L). A statistically significant elevation is seen in these two parameters in Group 2 as compared to Group 1. There was a negative significant correlation between eGFR and AST/ALT levels in Group 1 (p < 0.05). In Group 2, a weak positive correlation was seen with ALT. Group 3, eGFR's showed strong correlations with AST and ALT levels; reduction in kidney function correlated well with increase in serum ALP levels. Conclusions: This study establishes that SARS-CoV-2 infected, with CKD, show higher elevations in serum aminotransferase levels in comparison to those without CKD. In contrast, the CKD group not infected, shows a decline in serum aminotransferase levels. Serum ALT values in SARS-CoV-2 show significant correlation with eGFR. Also, elevated ALP values in CKD patients may be used as an indicator of declining kidney function.
