Hunter–gatherer populations underwent a mass extinction in the Neolithic, and in present times face challenges such as explicit sedentarisation policies. An exception is in Nepal, where the nomadic Raute people receive monthly governmental individual payments. One consequence of the money transfers has been a significant increase in alcohol consumption, with nearly all individuals drinking industrially produced alcohol. Here we investigate the Raute demography based on a full census of 144 individuals. We show that the Raute exhibit the short life expectancies typical of other hunter–gatherer populations from Africa, Asia and America. Bayesian survival trajectory analysis demonstrated that heavy drinking by either parent substantially reduces offspring survival to age 15. Bayesian regressions revealed a significant effect of heavy drinking on maternal fertility by decreasing the number of living children and reducing the proportion of live children at the end of maternal reproductive life. Although the absence of data prior to monetary support precludes a direct assessment of long-term demographic trends, relatively stable population sizes over the last decades and a fertility rate close to the replacement rate rule out an imminent population crash. Further studies are required to elucidate the Rautes’ origins and relationship with other nomadic people in the region.

A growing number of institutions that hold cultural heritage artifacts are now considering voluntary repatriations in which they choose to return an artifact despite unfilled gaps in their knowledge of its ownership history. But how are institutions to judge whether it is more probable that such gaps conceal theft and illicit export or are innocuous? Attempting to answer this question for Nepal, we examine published and archival records to trace the history of the growth in collecting of Nepali cultural heritage in the United States, with special attention to a 1964 exhibition at New York’s Asia Society Gallery, “The Art of Nepal,” and the activity of the New York dealers Nasli and Alice Heeramaneck. We conclude that the majority of Nepali heritage items in America entered after Nepal prohibited their export.

Khata Corridor forest, which serves as a border crossing for wildlife between Nepal and India, is one of the areas in Nepal with the highest incidence of human–wildlife conflict. In recent years both the tiger Panthera tigris tigris and human populations in this region have increased, leading to more frequent conflict. We aimed to determine whether increased conflict risk was primarily from tigers entering human settlements or whether there are additional drivers associated with human use of forested areas. We conducted the study in four settlements that varied in socio-economic status and distance from Bardiya National Park, through field visits and household surveys. Tiger records (sightings, pug marks and attacks) were most frequent far from Bardiya National Park, in settlements without benefits from tiger-based tourism and nearer the periphery of forest, and were rarely associated with the interior of settlements. Human visitation into forests was also highest in the most remote settlement. Our findings suggest that conflict risk is driven by the extent of human activity in forested areas, reflecting an unequal distribution of the conservation benefits of tourism amongst settlements. In the long-term, continued coexistence between people and tigers will depend on minimizing conflict risk across settlements through establishing an equitable distribution of conservation benefits. In the short term, we recommend raising public awareness of tiger behaviour to emphasize that tigers are highly unlikely to enter and occupy the interior of human settlements, mitigating negative perceptions of conflict risk.

The Chinese pangolin Manis pentadactyla is categorized as Critically Endangered on the IUCN Red List but little is known about its status in Nepal. Although indirect sign surveys have reported its presence in several community forests in Kavrepalanchok district, no photographic or video evidence has previously been documented. We used camera traps to investigate the occurrence of pangolins in 20 community forests in Panauti Municipality in Kavrepalanchok. A total of 75 0.01 km2 plots were surveyed using camera traps during September 2022–February 2023, with a total survey effort of 803 trap-days. The cameras recorded a total of 16 individual video footage events of Chinese pangolins in six of the community forests. This is the first camera-trap evidence of the species' presence in these forest patches, and in Kavrepalanchok district. The pangolins displayed behaviours such as sniffing, gathering plant material and digging, between 18.00 and 1.00. The camera-trap records provide more accurate species identification and reliable information than indirect sign surveys, indicating camera traps are a useful surveying tool for rare, nocturnal and elusive pangolins.

In the current IUCN Red List assessment, the south-western distribution range of the brown bear Ursus arctos in Nepal ends in Upper Mustang, in the central Himalaya, and extends northwards into the Tibetan Autonomous Region of China. Although brown bears have been recorded further west of Upper Mustang, details of these findings have not been published previously. Using camera traps, we present new evidence of brown bears in Limi Valley, Upper Humla, north-western Nepal. Covering a study area of 336 km2, we deployed 61 camera traps for 3,145 trap-nights during July–October 2021 and 10,748 trap-nights during June 2022–October 2023. In 2021 we recorded a single independent image of a brown bear, followed by 23 independent images during 2022–2023. The images were captured during spring and autumn but not in summer and winter. These new records increase the distribution range of the brown bear in Nepal, extending its global range south-westwards. Our results indicate the significance of Limi Valley as a stronghold for brown bears in Nepal and underscore the importance of formally protecting the currently unprotected wildlife habitats in Limi Valley. Our study emphasizes the need for further research into the ecology and population status of brown bears in Nepal.

The identification and implementation of conflict reduction measures are necessary to reduce predator attacks on people and livestock and to minimize human encroachment into predator habitats. We identified potential human–tiger conflict reduction measures and prioritized these measures for Chitwan National Park, Nepal. We identified these measures through a literature review, key informant interviews and a local stakeholder workshop. We prioritized the identified measures using a questionnaire survey of victims of tiger attacks (farmers, forest users and fishers), beneficiaries of tiger conservation (tourist guides, Jeep and elephant safari operators, tour and hotel operators and business operators) and National Park managers. We identified 22 measures (12 preventative, five reactive and five mitigative) as having potential for reducing negative interactions between people and tigers. Amongst these, we identified compensation payments, tiger-proof fences and habitat and prey management as high-priority measures. Conflict reduction priorities also varied amongst stakeholder groups. The victims assigned the highest priority to the construction of tiger-proof fences, whereas beneficiaries identified the management of habitat and prey as their highest priority. Compensation payments were the first preference of National Park managers and were amongst the top two priorities of all stakeholder groups. We recommend the adoption of the identified stakeholder priorities for reducing human–tiger conflict around Chitwan National Park and encourage consideration of the variations in priorities between stakeholder groups during policy development and decision-making.

The gharial Gavialis gangeticus is a Critically Endangered crocodilian currently known from only 14 disjunct locations in Nepal and India. The protected stretch of the Babai River in Bardia National Park, Nepal, is home to one of the six subpopulations of gharials that have exhibited recent evidence of reproduction. However, there is limited information available on the gharial population in this region. We conducted surveys during the breeding, nesting and hatching seasons of gharials during 2020–2022 to study the gharial population in the Babai River in Bardia National Park. We located one breeding group of gharials in Soth Khola (2–3 individuals) and one in Dhanuse (5–6 individuals), and we observed pre-mating or mating behaviours in all 3 years. We identified potential nesting areas on sand banks of 19–175 m in length. During nesting seasons we found abundant signs of nesting only in Dhanuse, including entry and exit trails of female gharials to and from the water and trial nests. In 2020 and 2021 we did not find any signs of hatching, probably because of flooding. In 2022 we recorded two gharial nests, producing c. 60 hatchlings, in Dhanuse. Our findings indicate that the gharial population in the Babai River is probably nesting annually. We recommend various conservation actions for this gharial population.

We show that the exposure to war-related violence increases the quantity of children temporarily, with permanent negative consequences for the quality of the current and previous cohorts. Our empirical evidence is based on Nepal, which experienced a 10 year long civil conflict of varying intensity. We exploit that villages affected by the conflict had the same trend in fertility as non-affected villages prior to the onset of conflict and employ a difference-in-differences estimator. We find that women in affected villages increased their fertility during the conflict by 19%, while child height-for-age declined by 10%. Supporting evidence suggests that the temporary fertility increase was the main pathway leading to reduced child height, as opposed to direct impacts of the conflict.

This paper describes the development process of a mobile app-based version of the World Health Organization mental health Gap Action Programme Intervention Guide, testing of the app prototypes, and its functionality in the assessment and management of people with mental health conditions in Nepal. Health workers’ perception of feasibility and acceptability of using mobile technology in mental health care was assessed during the inspiration phase (N = 43); the ideation phase involved the creation of prototypes; and prototype testing was conducted over multiple rounds with 15 healthcare providers. The app provides provisional diagnoses and treatment options based on reported symptoms. Participants found the app prototype useful in reminding them of the process of assessment and management of mental disorders. Some challenges were noted, these included a slow app prototype with multiple technical problems, including difficulty in navigating ‘yes’/‘no’ options, and there were challenges reviewing detailed symptoms of a particular disorder using a “more information” icon. The initial feasibility work suggests that if the technical issues are addressed, the e-mhGAP warrants further research to understand if it is a useful method in improving the detection of people with mental health conditions and initiation of evidence-based treatment in primary healthcare facilities.

Jalthal Forest (62.6 km2) is a remnant forest patch of a once continuous, lush and dense area of sal Shorea robusta and mixed deciduous vegetation in eastern lowland Nepal that is now surrounded by a dense human population. The forest is one of the last remnants of suitable habitat for the Critically Endangered yellow-headed tortoise Indotestudo elongata. This study explored the distribution of and conservation threats facing the yellow-headed tortoise in Jalthal Forest through field surveys in 20 community forests and structured interviews with 80 members of 22 community forest user groups and local people during September–November 2021. We surveyed 11.3 km2 of the forest and observed only four individuals of I. elongata, indicating a population density of 0.35/km2. Local people perceived that the species is decreasing mainly because of hunting (42%) and habitat deterioration from incursion of invasive species (30%). Based on the interviews with local people involved in hunting, an annual mean of 6.8 tortoises were killed during 2017–2021. The purposes of hunting were consumption (70%) and ethnomedicinal uses (30%) by the Meche and Sathar communities. Awareness campaigns and networks of communication amongst all stakeholders are required to conserve this species in Jalthal Forest.

Mental disorders are the leading cause of disease burden, affecting 13% of all people globally in 2019. However, there is scarce evidence on the burden of mental disorders in Nepal. This study used the Global Burden of Disease Study 2019 data to assess the prevalence and disability-adjusted life-years (DALYs) of mental disorders in Nepal between 1990 and 2019. In 2019, there were 3.9 million (95% UI: 3.6–4.3) people with mental disorders in Nepal. Major depressive disorders (1.1 million; 95% UI: 0.9–1.2 million) and anxiety disorders (0.9 million; 95% UI: 0.8–1.2 million) were the most prevalent mental disorders in 2019. Attention deficit hyperactive disorder, conduct disorder, and autism spectrum disorders were present twice as high in males than in females. The proportional contribution of mental disorders to the total disease burden has tripled between 1990 (1.79% of all DALYs) and 2019 (5.5% of all DALYs). In conclusion, the proportional contribution of mental disorders to total disease burden has increased significantly in the last three decades in Nepal, with apparent sex and age differentials in prevalence and DALY rates. Effective program and policy responses are required to prepare the health system for reducing the growing burden of mental health disorders in Nepal.
