Background: Citrus ranks top among the agricultural export commodities of Bhutan both in terms of volume and value. However, citrus cultivation practices still remain traditional with very low yield and inferior fruit quality. This study adopted community approach to identify basic components of citrus orchard management. Citrus growers of Drujegang were trained on citrus orchard management and assessed the impact of training on the adoption of management technology and subsequent effect on the yield and household (HH) income for 40 randomly selected individuals.Results: Statistical results showed significant difference both in terms of adoption of improved orchard management practices (p = 0.04) and HH income generation (p = 0.01). Adoption of improved management practices increased from 4.54 % (in 2012) to over 16 % (in 2014) with a mean yield increase of 27.5 % (212 kg acre −1 ) over previous year. Similarly, mean production increased from 5376 (2012) Conclusions:Hands-on training on basic orchard management increased the rate of adoption and resulted in increased yield and production. Huge potential exists in enhancing the livelihood of citrus growers by taking forward the available orchard management technology to growers through appropriate research and extension intervention. Therefore, replication of similar participatory approach at community level is recommended in other parts of the country.

BackgroundHuman beings use plants for a multitude of purposes of which a prominent one across the globe is for their medicinal values. Medicinal plants serve as one of the major sources of income for high altitude inhabitants in the Himalaya, particularly in countries like Nepal, and Bhutan. People here harvest huge volumes of medicinal plants indiscriminately, risking their sustainability. This paper attempts to identify some of the priority medicinal plant species harvested in the wild and assess their ecological status for their judicious utilization, and to help provide policy guidance for possible domestication and support strategic conservation frameworks.ResultsOut of the 16 priority species identified by the expert group, collectors’ perception on ecological status of the priority species differed from survey findings. Chrysosplenium nudicaule (clumps) ranked as most threatened species followed by Corydalis dubia, and Meconopsis simplicifolia. Onosma hookeri, Corydalis crispa and Delphinium glaciale were some of the species ranked as threatened species followed by Halenia elliptica (not in priority list). Percent relative abundance showed irregular pattern of species distribution. High species evenness was recorded among Nardostachys grandiflora, Chrysosplenium nudicaule, Saussurea gossypiphora and Aconitum orochryseum with average species density of 8 plant m−2. Rhodiola crenulata, and Dactylorhiza hatagirea followed by Meconopsis horridula and Meconopsis simplicifolia were ranked as most threatened species with average species density of 0.4, 0.4, 5.6 and 6.0 plant m−2, respectively. The most abundant (common) species was Onosma hookeri (plant m−2). Species composition and density also differed with vegetation, altitude, slope and its aspects.ConclusionPriority species identified by expert group were found vulnerable and patchy in distribution. Survey results and collectors’ perceptions tally to an extent. Some of the species (Dactylorhiza hatagirea, Rhodiola crenulata, Meconopsis simplicifolia and Meconopsis horridula) were critically low in plant density with less than a plant per m2 while Delphinium glaciale, Fritillaria delavayi and Aconitum orochryseum were confined to narrow altitude range. Collectors were aware that most species identified in priority list are threatened and existing harvesting plan are hardly implemented as it is not pragmatic. Moreover, major chunk of medicinal plants harvested remain unaccounted as illegal harvest and marketing seemed to occur across the borders. Policing and monitoring would continue to be a challenge given the rugged terrain and harsh climate. In-depth study and further monitoring of low density species is suggested to ensure its sustainability through long term strategy development.Electronic supplementary materialThe online version of this article (doi:10.1186/s12898-016-0100-1) contains supplementary material, which is available to authorized users.

This study seeks to understand the transition of youthful rural migrants to urban areas of Bhutan. The goal is to help frame better policy guidelines and efficient intervention strategies. A majority of these migrants are school dropouts with socioeconomic problems who primarily left in search of a better life, despite having arable land to farm back in their home villages. Their urban earnings failed to cover their daily household expenses and other needs, thus affecting the kind and quality of life in an urban setting. Not enough support for migrant youth exists during such critical and vulnerable transition stages when they face the huge responsibilities of independent living early on in their lives. The future for these young migrants remains bleak in the absence of a clear-cut protective social support and an efficient intervention system.

Investigation into the relevance and utility of bridging gaps between knowledge and practice is necessary to justify such endeavors to public funding agencies. This study investigated the underlying causes of the research–practice gap in the Bhutanese context with the aim to realign the relevance of agricultural research and to enhance practice using Rogers innovation attributes on features of Mode 2 knowledge production features. Out of 233 articles published by three agricultural journal publishers, only 110 articles that met our criteria were included in this study. Principal component analysis (PCA) for 23 variables yielded five variables that contributed 90% of the total variation. The first two dimensions contained 39.34% of the total dataset inertia, which was significantly greater than the reference value (17.19%) obtained by simulating 959 data tables of equivalent size based on a normal distribution. Further, cluster analysis differentiated the observations into three distinct clusters that significantly differed in their variable descriptive values. The innovation attributes ‘complexity’ and ‘compatibility’ received the highest score, while ‘observability’ had the lowest score. Under innovation diffusion elements, ‘time’ and ‘social system’ aspects were the least considered, thus affecting the innovation adoption. The ‘context of application’ of innovation had the highest score (65%), whereas ‘diffusion’ of the knowledge under transdisciplinarity received the lowest score. Both the diversity of ‘discipline’ and ‘organization’ inclusion under heterogeneity received the lowest score. Informal communication and social dimension received the lowest score among the Mode 2 knowledge production variables. Bhutan followed conventional, linear, and unidirectional approaches to research and extension diffusion systems, by which research institutions innovate, and extension workers bring innovation to potential adopters. Bhutanese research policy and strategy must consider reframing relevant agriculture innovation systems to keep abreast of modern technology development.

Innovation contexts and associated elements determine the type of innovation and adoption. This study aimed at the understanding of the innovation policy and intervention mechanism within the Bhutanese Department of Agriculture (DoA). We developed a conceptual model from the themes and the OECD evaluation criteria based on the conceptual model. The national issues and opportunities related to the agriculture and forestry of Bhutan were defined, and policy gaps were identified between the national plan and the institutional programs that were implemented. A total of 67 government documents from the relevant agencies were collected, of which, 33 documents were included, based on the inclusion criteria that matched with the conceptual, thematic analytical model. Our results from the document analysis show that the institutional innovative interventions appeared relevant to the Bhutanese context; however, inadequate coherence (mapping and alignment) of the institutional intervention programs with the national issues and goals suggested the need for the Bhutanese agricultural innovation system to enhance the effectiveness and efficiency of the program results. Similarly, coordination and collaboration were found to be necessary to extract the synergistic impact of the innovative interventions at the various levels of administrative hierarchy. Institutional accountability and interventional coherence at different organisational levels needs reviewing in order to achieve the sustainability of the outcome in Bhutanese agricultural research.
