Background: Frontline Health Care Workers are at risk of developing mental and psychological distress during Corona virus disease 2019 pandemic. This study aimed to assess level of stress, anxiety, depression and their associated factors among health care workers during Corona virus disease 2019 pandemic in Nepal.Methods: This is a web based cross-sectional survey conducted among 404 Health Care Workers during early phase of Corona virus disease 2019 pandemic. The participants were selected using convenience sampling technique and were invited to participate via various online networks. Depression, anxiety and stress were assessed using the Depression Anxiety Stress Scale-21 (DASS-21) and their associated factors were measured using structured questionnaires. Multivariable logistic regression was carried out to determine the associated factors.Results: The symptoms of stress, anxiety and depression among health care workers were found to be 28.9%, 35.6% and 17.0% respectively. Females were found to be 2 fold more likely to have anxiety and depression than male. Nurses were found to be two times more likely to have anxiety than doctors. Laboratory personnel were almost three folds more likely to have anxiety than doctors. Health care workers with insufficient/ no PPE were almost three fold more likely to have depression. health care workers working in high-risk areas had almost 2 fold higher odds of having depression.Conclusions: Health care workers experienced symptoms of stress, anxiety and depression in varied level of severity. This experience was higher among the nurses and laboratory workers than doctors. Pandemic preparedness assuring PPE and appropriate psychological interventions may be beneficial to promote mental health and well-being of health care workers.Keywords: Anxiety; associated factors; depression; health workers; stress

Silvopastoral systems in New Zealand that incorporate trees planted to control soil erosion on hills largely rely on the productivity of the pastoral system for financial returns. The effect on pasture productivity of increasing the tree canopy height by pruning Italian gray alder (Alnus cordata) was investigated by measuring the response of light, soil moisture, soil temperature, pasture production of major pasture species, and grazing behaviour of sheep. A split-plot design with four replicates was used. The main plot treatments were three levels of shade (81, 23, and 12% of available photosynthetic photon flux (PPF)), created by pruning 11 year old alder grown at the same density. The sub-plot treatments were four pasture mixes: perennial ryegrass (Lolium perenne), Yorkshire fog (Holcus lanatus), and cocksfoot (Dactylis glomerata), each sown with white clover (Trifolium repens), and cocksfoot sown with lotus (Lotus pedunculatus). Soil temperature was highest under light shade. Total herbage yield at 50 mm stubble height from October to May under heavy and medium shade was 60 and 80%, respectively, of the total herbage harvested under light shade. Cocksfoot had the greatest herbage yield, either with lotus or white clover. The tillering of perennial ryegrass was suppressed by shade more than for the other grass species making ryegrass unsuitable for use in this silvopastoral system. More sheep grazed in the light shade than in the heavy shade, but there was no difference in sheep preference for cocksfoot or Yorkshire fog. Lotus was grazed more frequently than white clover. Pruning of alder to increase canopy height has the potential to improve the productivity of the understorey pasture and its acceptability to sheep.

Increasing livestock production to meet growing demands has resulted in greater interactions at the livestock-wildlife-human interface and more opportunities for zoonotic disease spread. Zoonoses impose enormous burdens on low-income countries like Nepal, where populations are largely dependent on livestock production and access to shared grazing lands, often near protected areas, due to population pressures. Several livestock-associated zoonoses have been reported in Nepal; however, little is known regarding Nepali farmers' knowledge of zoonoses and opportunities for disease management. We conducted a cross-sectional study to investigate Nepali farmers' awareness of zoonoses, assess current health challenges, and evaluate disease prevention and control practices. We found that awareness of zoonotic pathogens was limited, especially in informally educated and illiterate farmers; the majority of which were women. Further, farmers' preventive herd health, food safety, and sanitation practices were not associated with their awareness. Several farmers reported high-risk practices despite being aware of zoonotic diseases, suggesting a disconnect between the farmers' awareness and practice. Our study highlights the need for improving Nepali farmers' knowledge of zoonoses and disease prevention measures. Closing these awareness-practice gaps will require an improved understanding of risk and effective drivers of behavior change, alongside engagement of farmers in development of zoonotic disease prevention programs that encourage participation of both male and female farmers across all levels of education.

Nepal has an extreme altitudinal range from 60-8850 m with heterogeneous topography and distinct climatic zones. The country is considered a biodiversity hotspot, with nearly a quarter of the land area located in protected areas. Nepal and the surrounding Himalayan region are particularly vulnerable to climate change because of their abrupt ecological and climatic transitions. Tens of millions of people rely on the region's ecosystem services, and observed and modeled warming trends predict increased climate extremes in the Himalayas. To study the ecological impacts of climate change in Nepal and inform adaptation planning, we review the literature on past, present, and predicted future climatic changes and their impacts on ecological diversity in Nepal. We found few studies focusing on organisms, while research on species and communities was more common. Most studies document or predict species range shifts and changes in community composition. Results of these few investigations highlight major lacunae in research regarding the effects of changing climate on species comprising the Himalayan biota. Further empirical work is needed at all levels of biological organization to build on information regarding direct ecological impacts of climatic changes in the region. Countries face an ever-increasing threat of climate change, and Nepal has strong physiographic, elevational, and climatic gradients that could provide a useful model for studying the effects of climate change on a mountainous, and highly biodiverse, area.
