Cystic echinococcosis (CE), caused by Echinococcus granulosus s.l. is a neglected zoonosis posing a significant public health challenge. Little is known about human CE in Bhutan. This study was conducted to gain an understanding of the burden, distribution, and potential risk factors of CE in Bhutan. From January 2015 to December 2019 data from Jigme Dorji Wangchuck National Referral Hospital (JDWNRH) and 6 other district-level hospitals were reviewed. Descriptive statistics were used to summarize the data. DALYs and Poisson regression models were used to estimate the burden and explore the relationship between cases and possible risk factors. A total of 159 cases were recorded. Most cases (145) were admitted to the surgical ward and 14 cases were referred to India. The average annual incidence was 4.4 cases per 100 000 population. The burden of disease was estimated to be approximately 39 DALYs per year for treatment-seeking cases, or possibly 80 DALYs per year including non-treatment seeking cases. This translates to approximately to 5.2 DALYs and 10.2 per 100 000 per year respectively. The commonest sites of infection were the liver (78%) and lungs (13%). Most cases were treated with surgery (>82%), and more than 47% were admitted to the hospital for >4 days. Policy interventions targeting community engagement, awareness, education, high risk occupational groups, females, and those living in the endemic districts of the central and western regions may yield larger gains. More studies and the institution of a surveillance system can help better guide policy interventions.

The rare Himalayan wolf Canis lupus chanco is categorized as Vulnerable on the IUCN Red List, and there is limited knowledge of its ecology and distribution. In Bhutan, the Himalayan wolf is one of the least known carnivores. Our aims in this study were to map the current distribution of the wolf in Bhutan and to identify potential habitats within the country. We compiled 32 records of wolf presence from camera-trap surveys and, using a maximum entropy approach, we estimated a potential habitat of 2,431 km2, comprising c. 6.3% of Bhutan. However, wolf presence was localized and non-continuous. We recommend a detailed fine-scale habitat analysis in areas of potential habitat and genetic studies to investigate population structure. Knowledge of these matters will provide insights regarding connectivity and facilitate the development of conservation strategies for this threatened wolf.

The Endangered tiger Panthera tigris and Vulnerable snow leopard Panthera uncia are umbrella species and conservation priorities. Jigme Dorji National Park is an important protected area for the conservation of both species because it serves as a source site for tigers to adjacent areas and has the largest snow leopard population in Bhutan. Habitat overlap of tigers and snow leopards in Bhutan has been previously reported based on evidence of tigers (pugmarks, livestock killed and camera-trap images) in known snow leopard habitat above 4,000 m altitude. Here we report the first photographic evidence of both tigers and snow leopards at the same locations, confirming habitat overlap and co-occurrence of the two species. The data are derived from the countrywide tiger survey carried out during October 2021–January 2022. Fifty-six pairs of camera traps were installed in a 5 × 5 km grid at an altitude range of 1,200–4,300 m. After a survey effort of 1,528 trap-nights, 478 tiger images and 31 snow leopard images were captured at 12 and three camera stations, respectively. At all three camera stations that captured snow leopard images, tigers were also captured. These findings indicate the habitat overlap and co-occurrence of tigers and snow leopards in Jigme Dorji National Park. Further research is required to inform conservation practice in the National Park focusing on these apex predators.

Seven varieties of forage oats from China were evaluated in the temperate environment of Bhutan for morphological traits, dry matter production, and forage quality. The oat variety Qingyin No. 1 provided a greater plant height (61 cm) and the largest number of tillers per plant (five tillers per plant). The leaf-stem ratio (LSR) was highest for Longyan No. 2 (LSR 0.73). During harvest in late winter, Longyan No. 2 had a greater plant height (64 cm) and the highest number of tillers per plant (seven tillers per plant), followed by Qingyin No. 1. The top three varieties with high LSRs of 1.49, 1.31, and 1.35 were Longyan No. 1, 2, and 3, respectively. In both summer and winter, Longyan No. 2 had the highest forage yields of around 5.00 and 4.00 DM t/ha, respectively. Qingyin No. 1 was the second largest forage producer, with under 5.00 DM t/ha in summer and under 3.00 DM t/ha in winter. For forage quality, Longyan No. 2 and Longyan No. 3 had the highest levels of crude protein (15%) in summer. However, during late winter, the Linna variety had the highest crude protein content (13%). The overall results of the field experiments suggest that Longyan No. 2 and Qingyin No. 1 are promising new oat varieties for winter fodder production in the temperate environments of Bhutan.

In the last decade the tiger Panthera tigris population in the Terai Arc Landscape and Himalayas has increased, while populations in other countries have remained below their conservation targets. Although there has been some research on tiger conservation in the Terai Arc Landscape and the Himalayas, scientists and managers have not catalogued and characterized tiger research in the region, with empirical findings scattered among disparate document types, journals and countries. Without a review of the tiger research in the Terai Arc Landscape and Himalayan region, it is difficult to analyse or change conservation policies, develop adaptation strategies, prioritize research, allocate resources or develop conservation strategies potentially employable elsewhere. We therefore conducted a systematic scoping review to identify focal research areas, the spatial and temporal distribution of study sites, general publication trends, the extent of empirical studies, and gaps in tiger conservation research in this region (which spans Bhutan, India and Nepal). Since 2000, 216 studies have been published on issues associated with tiger conservation in the Terai Arc Landscape and Himalayas, with an increasing number over time. Most empirical studies have focused on tiger habitat, ecology and conflicts in protected areas in the region's foothills. There are research gaps in high-altitude landscapes, social science investigations, conservation economics, and policy and institutional analyses.

This article posits that friendship has been a particularly fertile and creative category against the backdrop of imperial expansion and consolidation in the Himalayas. As a small but strategically perceived sovereign Himalayan country, Bhutan's history through the last centuries has been marked simultaneously by imperial and post-colonial asymmetries of power. The term “friendship” is deployed as a key diplomatic category in Bhutan's most significant relationship, that with its much larger neighbour India. However, the origin of this friendship is always traced back to the mid-twentieth-century post-colonial period. In contradistinction to this, I constellate a much longer history of this friendship with a special focus on the landmark 1910 Treaty of Punakha between Bhutan and Britain, which was a key turning point in Bhutan's relations with its southern neighbour (British India at the time). Scholars typically state as a matter of fact that in the year 1910, with the initiative of Political Officer Charles Bell, a treaty was signed between Britain and Bhutan that placed Bhutan's external relations under the guidance of Britain. This present work is situated within the oeuvre of critically rereading imperial sources and evaluating their historical legacies, and is the first detailed scholarly analysis of why this treaty was significant and how it came to be signed. I identify the factors that were at work in how and why the 1910 friendship treaty was realised for imperial British purposes—the interpersonal friendships fostered by the British Political Officers; the threat of China as an Other; and the representation of material and ideational advantages from associating with an imperial power. In making this argument, I analyse the role played by the vocabulary of friendship and draw upon primary archival sources to illustrate the factors that were at work as well as the dissonance between the archival and public rationales provided by Political Officer Bell. The 1910 treaty was signed at a watershed moment after the then-recent installation of a monarchy in Bhutan in 1907, and against the great game backdrop of Qing activities in Tibet and British interests in the region; throughout the twentieth century, the impact of this friendship treaty was of paramount significance, and its shadow continues into the twenty-first century.

Differentiated instruction (DI) is an inclusive teaching approach that recognises and values student differences. Teachers teaching in inclusive schools practise DI to accommodate students with special educational needs and disabilities. However, no research has yet been conducted to explore teachers’ perceptions of DI in Bhutan. The purpose of this quantitative study is to explore teachers’ perceptions of DI and the differences in their perceptions based on demographic variables. Data were collected via an online survey from 185 teachers in 19 inclusive schools and were analysed using descriptive and inferential statistics. The results indicated that the majority of teachers had favourable perceptions of DI. No significant perceptual differences were found on qualifications and teaching experiences. However, special education teachers’ perceptions of DI were significantly higher than general education teachers (M = 4.14, SD = .37), (M = 3.89, SD = .41), respectively, t(183) = 4.194, p = .000, and trained teachers’ perceptions of DI were also found to be significantly higher than untrained teachers (M = 4.09, SD = .39), (M = 3.81, SD = .40), respectively, t(183) = 4.090, p = .000. The implications of the research findings are discussed with recommendations for further research in this area.

Supraglacial ponds and ice cliffs can dramatically enhance ablation rates on debris-covered glaciers. Supraglacial ponds can also coalesce, forming moraine-dammed lakes at risk of glacial lake outburst flood (GLOF). Given Bhutanese glaciers have some of the highest ice loss rates in the Himalaya and GLOF vulnerability is high, we seek to advance our understanding of the spatial distribution and evolution of supraglacial ponds and ice cliffs. Here, we use high-resolution (3 m) Planet Labs satellite imagery to provide the first short-term, high-resolution dataset of supraglacial pond and ice cliff evolution for three glaciers along the Bhutan–Tibet border from 2016 to 2018. A total of 5754 ponds and 2088 ice cliffs were identified. Large intra-annual changes were observed, with ponded area changes and drainage events coinciding with the seasonality of the Indian Summer Monsoon. On average, ~19% of the total number of ponds had a coincident ice cliff. Pond spatial distribution was driven by ice-surface velocities, with higher numbers of ponds found in areas of low velocity (<8 m a−1). Our study provides the first detailed, quantitative investigation of supraglacial ponds and ice cliffs in Bhutan, providing a framework for further monitoring in this understudied, yet important, region of the Himalaya.

Site occupancy models, accounting for imperfect detection and the influence of anthropogenic and ecological covariates, can indicate the status of species populations. They may thus be useful for exploring the suitability of landscapes such as biological corridors, to ensure population dispersal and connectivity. Using occupancy probability models of its principal prey species, we make inferences on landscape connectivity for the movement of the tiger Panthera tigris between protected areas in Bhutan. We used camera-trap data to assess the probability of site occupancy (Ψ) of the sambar Rusa unicolor, wild boar Sus scrofa and barking deer Muntiacus muntjak in biological corridor no. 8, which connects two national parks in central Bhutan. At least one prey species was recorded at 17 out of 26 trapping locations. The probability of site occupancy was highest for the barking deer (Ψ = 0.52 ± SE 0.09) followed by sambar (Ψ = 0.49 ± SE 0.03) and wild boar (Ψ = 0.45 ± SE 0.07). All three species had higher occupancy probability at lower altitudes. Sambar occupancy was greater farther from settlements and on steeper and/or south-facing slopes. Barking deer also had higher occupancy on south-facing slopes, and wild boar occurred mainly close to rivers. Our findings suggest that this biological corridor could facilitate dispersal of tigers. Protecting prey species, and minimizing anthropogenic disturbance and habitat fragmentation, are vital for tiger dispersal and thus functional connectivity amongst populations in this area.

In this article, I interrogate the exhaustive “inbetweenness” through which Bhutan is understood and located on a map (“inbetween India and China”). I argue that this understanding naturalizes a contemporary geopolitics with little depth about how this inbetweenness has shifted over the centuries, thereby constructing a timeless, obscure, and remote Bhutan that is “naturally” oriented southward. I trace how the construction of Bhutan's asymmetrical inbetweenness is nested in the larger story of the formation and consolidation of imperial British India and its dissolution, and the emergence of post-colonial India as a successor state. I identify and analyze the key economic dynamics of three phases marked by commercial, production, and security interests, through which this asymmetrical inbetweenness was consolidated. Bringing together sources from different disciplines and archival work, this account also challenges some of the dominant historical scholarship on Bhutan in each phase. I conclude by emphasizing that critical work at the intersection of geographical/political/historical contingencies is important to the subalternizing of geopolitics, which recognizes the myriad ways in which dominant powers have shaped both the geopolitical environment as well as knowledge-making that has constrained small states.

White-bellied Heron Ardea insignis (WBH) is critically endangered, but we lack data on many aspects of its basic ecology and threats to the species are not clearly understood. The goal of this study was to analyse WBH foraging microhabitat selection, foraging behaviour, and prey preferences in two river basins (Punatsangchhu and Mangdechhu) in Bhutan which are likely home to one of the largest remaining populations of WBH. We also explored the relationship between the relative abundance of the WBH and prey biomass catch per unit effort within four foraging river microhabitats (pool, pond, riffle and run). Prey species were sampled in 13 different 100-m thalweg lengths of the rivers using cast nets and electrofishing gear. Riffles and pools were the most commonly used microhabitats; relative abundance was the highest in riffles. The relative abundance of WBH and prey biomass catch per unit effort (CPUE) also showed a weak but significant positive correlation (rs = 0.22). The highest biomass CPUE was observed in riffles while the lowest was found in the ponds. From the 97 prey items caught by the WBH, 95% of the prey were fish. The WBH mainly exploited three genera of fish (Garra, Salmo, and Schizothorax) of which Schizothorax (64%) was the most frequently consumed. This study provides evidence in support of further protection of critical riverine habitat and fish resources for this heron. Regular monitoring of sand and gravel mining, curbing illegal fishing, habitat restoration/mitigation, and developing sustainable alternatives for local people should be urgently implemented by the government and other relevant agencies. Further study is also required for understanding the seasonal variation and abundance of its prey species in their prime habitats along the Punatsangchhu and Mangdechhu basins.

This paper reports the findings from a study investigating Bhutanese parents’ involvement in supporting their children with special educational needs (SEN) in schooling. The interaction between the parents themselves in supporting each other was also explored. Individual interviews were conducted with 26 parents (13 fathers and 13 mothers) of children with either full inclusion or partial inclusion in 3 schools located in 3 regions (urban, semi-urban, and rural) and analysed using manual thematic coding and Leximancer text mining software. Of Epstein’s (1987) 6 types of parental involvement activities in education, these parents reported their actions to be parenting, volunteering in schools, supporting learning and development at home, and collaborating with the community. The minimal interaction among the parents was mostly between the stay-in-school urban mothers who had consistent but impromptu and informal interactions. The implications of this study inform the need for schools to respond to policy and to actively engage parents, and for education programs and support groups to be set up to strengthen parental involvement in the education of children with SEN in Bhutan.

As part of the Convention on Biological Diversity (CBD), the Nagoya Protocol on Access and Benefit Sharing calls for ‘fair and equitable sharing of benefits’ derived from the use of genetic resources and traditional knowledge. However, implementation of the Convention and the Nagoya Protocol has been challenged by the inadequacies of existing policies, lack of national-level frameworks, and inadequate knowledge among stakeholders. We used focus group meetings and structured interviews with rural communities, government representatives, researchers and Members of Parliament in Bhutan to collect data on awareness, knowledge and perceptions of components of the CBD related to access and benefit sharing. Our study indicated generally low levels of awareness about most components of the Convention, particularly among rural residents. Although local people in rural communities feel that benefits derived from local biological resources and traditional knowledge should be shared, there is uncertainty about who owns these resources. These results indicate that there is an urgent need to develop educational and awareness programmes, using a variety of media, to target particular stakeholder groups, with emphasis on residents in rural communities. This could empower local communities to participate meaningfully in decision-making processes to develop Bhutan's national access and benefit sharing framework, and to allow them to benefit from the conservation and sustainable use of local resources.

We assessed local knowledge of and attitudes towards a large, endemic bovid, the Bhutan takin Budorcas whitei, within its seasonal range in Jigme Dorji National Park, Bhutan. Using semi-structured questionnaires, data were collected in March 2015 from interviews with 169 park residents. A conditional inference tree analysis was used to explore associations between demography, locality, and secondary response variables through questions relating to respondents’ knowledge of the takin's status as a protected species, a Vulnerable species, and as the national animal. Most respondents knew the takin was Bhutan's national animal, and of those, a significantly high proportion also knew of its protected status. Significantly more respondents residing in the species’ summer, rather than winter, range were aware of the takin's Vulnerable status. Most respondents expressed positive feelings towards the takin and supported its protection. This strong positive attitude, in conjunction with awareness-raising efforts, could be valuable for promoting the takin as a montane flagship species.

An assessment of management effectiveness was carried out for all the protected areas in the Kingdom of Bhutan. During 2014–2016 the Royal Government of Bhutan developed a custom-made tool for assessing management effectiveness: the Bhutan Management Effectiveness Tracking Tool Plus (Bhutan METT +). This was implemented in Bhutan's 10 protected areas and one botanical park, and the results were verified through field trips and expert reviews. The assessment indicates that protected areas in Bhutan are well managed and there are generally good relationships with local communities, despite an increase in livestock predation and crop damage. However, effectiveness is limited by a low level of resources (both financial and appropriate technical resources) and by gaps in monitoring and research data, which limits the ability to understand the impact of conservation, react to changing conditions and undertake adaptive management to improve efficiency and effectiveness. Bhutan is in the midst of mobilizing considerable conservation funding. The Government is working in partnership with WWF to create an innovative funding mechanism for the protected area system: the Bhutan for Life initiative. The Bhutan METT + study provides an example of how to develop a baseline against which to measure the effectiveness of protected areas over time and assess the impact of conservation inputs.
