Vulnerability of Pastoralism: A Case Study from the High Mountainsof Nepal

: Pastoralism in the Himalayan region of Nepal has undergone signiﬁcant socio-economic and ecological changes. While there are numerous contributing factors behind these changes, the e ﬀ ect of a changing climate has not been thoroughly studied. This paper adds a signiﬁcant contribution to the knowledge base through analysis from a survey of 186 herder households, interviews with 38 key participants, and four focus group discussions with individuals from three National Parks and Conservation areas in the high-mountain region of Nepal. Additionally, a review of the existing policies and programs on pastoralism was carried out. Results demonstrate several reasons behind the decline of transhumance pastoralism: Policy focus on the establishment of conservation areas, increasing vulnerability to extreme events (avalanches, snowfall, storms, and disappearing water sources), and ine ﬀ ective government policies and programs. Hardships involved in herding combined with changing social values and the degradation of pasture quality were identiﬁed as contributing factors to the growing challenges facing mountain pastoralism. Similarly, the declining interest among herders to continue their profession can be traced to vulnerability associated with escalating climate change impacts. Considerable knowledge gaps regarding threats to high-altitude pastoralism remain, and continued research on pastureland conservation, capacity development, facilitation for climate change adaptation, and coping strategies for herders in the high mountains is urgently needed. Our analysis suggests that non-climatic variables such as policy and globalization were more inﬂuential in eroding pastoralism as compared to climate change. protection oriented policies, several institutions are here with restrictive rules that have made herding di ﬃ cult. Nowadays it is hard to graze freely and even the quality of pasture is poor ”.


Introduction
Vulnerability is a pervasive facet of livelihoods in the Hindu Kush Himalaya (HKH) region and has always beena harsh reality of the high-mountain environment [1]. Jodha [2] elucidated that mountains in the HKH regions have specific characteristics, such as fragility, marginality, inaccessibility, and poverty. These characteristics are expressed in the vulnerability of the mountain people. In recent decades, human activities, changes in land-use, and climate change have accelerated this vulnerability across all ecosystems in the Himalaya region [3]. Indeed, to a considerable degree, poverty and vulnerability overlap: Both being multidimensional in nature with common causes that lead to similar risks and outcomes [1]. This is further exacerbated by climate change and environmental degradation due to the local inhabitant's dependence on ecosystem services for their livelihoods.
of Nepal out of which 23.9% belongs to the High Himal region [26]. It encompasses the northernmost part of Nepal on the border with Tibet and lies to the north of the Mid-Hills region with an altitudinal range beginning at 2000 m of elevation up to alpine pastureland at approximately 4500 m [27]. Transhumance agro-pastoralism practices are prevalent at different altitudes in different seasons and various ethnic groups utilizing mixed farming systems and livestock species are found throughout the region (Table 1).   The high-mountain region covers parts of 25 districts and constitutes 44.3% of the total land area of Nepal out of which 23.9% belongs to the High Himal region [26]. It encompasses the northernmost part of Nepal on the border with Tibet and lies to the north of the Mid-Hills region with an altitudinal range beginning at 2000 m of elevation up to alpine pastureland at approximately 4500 m [27]. Transhumance agro-pastoralism practices are prevalent at different altitudes in different seasons and various ethnic groups utilizing mixed farming systems and livestock species are found throughout the region (Table 1).

Data Collection and Anlysis
This study employed both qualitative and quantitative research approaches to collect primary and secondary data at the field level. Data collection was carried out from January to March in 2018. Three key instruments were used for data collection: Key informant interviews, focus group discussions, herder's surveys, and a household survey questionnaire. Similarly, review and analysis of policy documents relevant to the vulnerability of the pastoral management practices were completed. The surveys primarily focused on the issues around grazing management, rangeland improvement activities, and rules and regulations for grazing (dejure and defacto practices). Review and analysis were focused on farming practices of transhumance pastoral systems, as well as legal and institutional frameworks for livelihood support programs in the area. Equally, there was a focus on the vulnerability, context, and influence in pastoral communities, such as: Household income from various farm and off-farm activities, farm labor availability, migration, marketing, resource availability, perceptions of climate change, and adaptation measures in the changing context within each of the survey instruments.
The survey tools were initially tested and further refined before effective data collection began. Prior consent from herders and key informants were obtained before we began the survey through verbal agreements between the researchers and the interviewee/participants. In addition, the objectives of the research and its application and outcomes were explained to the respondents. The data collection process was initiated through focus group discussions, which were conducted within four key groups, each representing one study site. These groups were comprised of 10 to 15 participants each, with each discussion lasting for approximately 2 h. There was a total of 38 key informant in-depth interviews conducted to discuss certain issues, which might not have been openly discussed within the group setting. A total of 186 surveys were conducted among herders at the household level (Table 2).
Secondary data consisted of long-term meteorological data from nearby weather stations (temperature and precipitation) collected by the Department of Hydrology and Meteorology (DHM), Government of Nepal. Likewise, information on livelihood improvement activities provided to the local communities was obtained from the National Park and Conservation Area office records.
The data were reviewed, coded, and entered into Microsoft Excel and the Statistical Package for Social Sciences (SPSS). The data were processed and reviewed to verify for accuracy before being analyzed using basic descriptive statics. The results are presented in the form of graphs, table and figures with narrative descriptions, and discussion of the findings presented as case studies and individuals stories.

Changing Livelihood of the Pastoral Communities
We found the farming of livestock to be one of the main occupations and income sources of the mountain pastoral communities followed by regular jobs and wage labor. Most of the households practiced a mixed farming system, i.e., transhumance pastoral system with crop production on their homestead farmlands. As noted by other authors, animal husbandry is a mainstay of the subsistence economy in the mountainous region of Nepal [28,29]. Livestock farming contributesbetween46%and 67% of the household incomes, annually (Table 3). Moreover, livestock production, along with crop production and pastureland, are interlinked with the sustainability of mountain farming systems. This unique combination has helped enhance the mountain farming, since livestock also produce manure to maintain the soil fertility as well as providing the draught power needed to plow the farmland. Similarly, in-situ manuring through livestock herding on pasture land helps to maintain soil fertility. However, we observed a decreasing trend of livestock farming in the study areas along with a labor shortage for transporting farmyard manure, there by resulting in increased use of chemical fertilizers for crop production. The increasing trend of migration to cities and abroad for education, jobs, and business has resulted in a shortage of labor nationwide. Studies suggest that increased income opportunities are driving this migration pattern [30] with populations usually migrating from areas of low economic opportunities to areas with better opportunities. Thus, ultimately, the changing livelihoods among pastoral communities from traditional mixed farming systems to more market-driven opportunities are leaving farming systems in the mountain region in an unsustainable situation.
However, a mixed strategy may offer a diversified livelihood, thereby reducing risk by spreading it across various enterprises [31]. This could be a positive approach towards countering contemporary threats such as climate change. Such strategies also play an important role for reducing the impact of food and nutrition insecurities [31,32]. Transhumance pastoral systems offer considerable value for sustainability through their ecological knowledge, indigenous practices, beliefs, and culture, which enhances the capacity and resilience of traditional agro-pastoral systems [33][34][35]. The integration of such knowledge, when combined with scientific approaches and technologies, may also result in the effective management of livestock and rangeland resources [36,37]. The pastoral communities of the Himalayas utilize sensitive resources, such as high-mountain pastures, through three modalities; namely, characteristic mobility patterns, socio-economic organization, and property rights. Thus, there is a need for urgent action through policy and program instruments to conserve the unique livelihoods developed over centuries by the Himalayan mountain community.
Furthermore, Acharya and Baral [24], as well as Banjade and Paudel [23], stress that the livelihoods of the transhumance pastoralists are threatened due to a number of socio-cultural, economic, and ecological stressors. Similarly, a concurrent degradation of high-elevation forests and a subsequent loss of biodiversity further exacerbate the livelihood security of these pastoral communities. This is supported in a study by Bhusal and others [15], that reported on excessive deforestation and forest degradation at high elevations. On top of this, newly emerging markets, increased awareness and demand for education, and increasing opportunities for employment in urban centers threaten the way of life of the traditional pastoralists [23].

Vulnerability and Adaptation of the Pastoral Communitiesto Climate Change
The context of vulnerability in this study is explained in terms of exposure and sensitivity to the climatic and non-climatic factors affecting the pastoral communities and their adaptation of livelihood strategies. Both data collected in the field and a review of existing literature were considered in the analysis of the vulnerability. Our results support the hypothesis that pastoral communities in the Himalayas have been impacted by multiple stressors, such as extreme climate events (snowstorms, avalanches, and landslides) that are unpredictable and catastrophic in nature. Similarly, the changing socio-economic context and lack of focus on effective policies and programs for high-altitude pastoralism have contributed to the decline of the transhumance pastoral system. Therefore, the authors have focused the analysis of the vulnerability of pastoral communities and adaptation strategies on the following three aspects: • National policy and institutional frameworks, • Modernization and changing social values, • Climate change impacts.

National Policy and Institutional Frameworks
We found that the policies and institutional frameworks including the Forest Act of 1993 [38], the Local Self Governance Act of 1999 and the Pastureland Nationalization Act of 1974 have led to increased bureaucracy and complexity by creating multiple authority structures with overlapping jurisdictions. Over several generations, villagers who had adopted transhumance systems as their primary livelihood strategy were forced to modify their practices due to changing policies and priorities of the government. These acts and regulations effectively ended the traditional management system, and local users' rights and interest in pastoral management systems were gradually eroded.
The National Park and Conservation Area Act and Regulations have also had the effect of restricting grazing in rangeland areas lying within Protected Areas. Similarly, the Forest Act of 1993, which includes a provision to hand over the forest management rights to local communities (Community Forests), has the unintended consequence of excluding the rights of the transhumance pastoral community to freely graze their livestock in the community forest in Mountain areas [15,24,34,39]. For example, paraphrasing one of the survey respondents (a 70 year old herder): "Before, we used to graze our livestock freely in these forests without any restrictions. However, after the implementation of Sustainability 2020, 12, 2737 7 of 15 protection oriented policies, several institutions are here with restrictive rules that have made herding difficult. Nowadays it is hard to graze freely and even the quality of pasture is poor".
It is estimated that around 27% of the area in rangeland in Nepal lies within National Park and Conservation Area boundaries, and of this, 80% exists in the High Mountains Region [40]. It follows that the majority of high-mountain and alpine zones have now been converted into National Parks and Conservation Areas across Nepal. This situation has created conflicts between the authorities charged with protection and the local herding communities who are struggling to access resources in high-mountain areas (14). Furthermore, livestock predation by wild carnivores is also increasing, particularly by leopards, which only adds to a greater vulnerability of the pastoral communities. For instance, within the study areas, a total of 152 livestock were killed over the last two years (2017 and 2018, Table 4). In the past, herders used to employ dogs to watch over their flocks of sheep and herds of goats as an early warning system. However, presently, park authorities do not allow the use of dogs within or near park boundaries. These policies and provisions have added to the vulnerabilities felt by the pastoral communities. As a result, the number of herders continues to decline as they seek alternative livelihood options such as tourism, trek guiding, and hospitality management; while those left behind struggle to survive with decreased mobility. This has a direct impact of the decline of transhumance grazing practices (14).
Adding to the complexity of policy formulation and implementation, Nepal has recently adopted a Federal structure with three tiers of government (i.e., Central Government, Provincial Government, and Local Government at the Municipality level). The present constitution (2015) gives the responsibility of natural resource management and livestock development to the Provincial and Local Governments. However, we observed that rangeland management is being neglected by these local institutions in both planning and programs. This has created confusion and further degradation of the limited natural resources. For illustration, herders have long complained that the intensive collection of medicinal plants, such as Cordyceps sp., results in mass movement of workers, camping in sensitive areas, littering, and the excavation of sensitive grassland, resulting in further degradation of the rangeland.
On the other hand, we found some positive aspects of policy implementation that has helped to reduce pastoral vulnerability in some manner. For instance, there is a provision to allocate from 30% to 50% of Park revenue to be utilized in the buffer zone area surrounding the Parks for resource conservation, development, and livelihood improvement of the local communities. This is achieved through the formation of Buffer Zone User Groups (BZUGs) and Councils as per buffer zone management regulations of 1996 and guidelines from 1999 [41].
The study found that income-generating activities, livestock development programs (such as veterinary services, fodder, and forage production both within the buffer zone area and on private land), improved vegetable farming, ecotourism promotion, etc., were practiced in the high-mountain region buffer zone areas. Similarly, several capacity enhancement training courses were provided by Park staff to the user groups. Stakeholders were served primarily in impoverished communities with a focus on the poor, marginalized people, and women, in an effort to enhance their livelihoods and promote sustainable resource management in the buffer zone area. These initiatives have played a role in reducing the pressures on resources surrounding the Parks while simultaneously enhancing local community participation in the management of resources in the National Parks and Conservation Areas and Buffer Zone Areas. Additionally, provision of compensation mechanisms [42] for livestock predation from wild carnivores has also had positive impacts on these pastoral communities (Table 4). There is evidence that these activities have helped to improve the livelihoods of some of the pastoral communities in the study area, in addition to improving rangeland management to some extent. Other studies in Nepal have also reported enhanced livelihoods of buffer zone communities due to: Income diversification, capacity enhancement, resource conservation, ecotourism promotion, increased farm production, and reduced conflict between Park authorities and communities through revenue distribution schemes [43][44][45].

Modernization and Changing Social Values
Despite their remoteness, mountainous regions do not exist in isolation. In fact, these regions are increasingly connected with the global community through the expansion of roads, airports, tourism, migration, and communication networks. Thus, globalization has resulted in pastoral societies now dealing with the realities of increased exposure to opportunities and challenges of markets, off-farm activities, jobs abroad, tourism and hospitality, and remittance payments. This has altered social values and therefore made traditional herding occupations less attractive than in the past [15]. We found that in general, younger generations were less motivated or interested in continuing this traditional occupation as compared to their parents and grandparents and would rather opt for regular employment in urban centers, migrating abroad for employment, or pursuing higher education opportunities in nearby cities.
One of the local elders surveyed shared: "the young generation has found this occupation to be less attractive from both the social and economic points of view. They have to tolerate the hardship of high altitude life throughout the year which they are simply not prepared to endure".
This has been a serious concern among the herders, and they are gradually abandoning this way of life. With the phenomenon of globalization, markets are emerging, advanced education is increasing, and multiple options for employment outside the community has led to a reduced interest in pursuing traditional pastoral practices [23].We observed that in all of the study areas, over 60%of the youth have moved either to the city or aboard in search of employment opportunities ( Figure 2). Eco-tourism opportunities are also gaining momentum as an attractive business within the study areas, particularly in Lamjung and Mustang districts of the Annapurna Conservation Area (Table 5).
Similarly, it has been reported that in recent years, particularly in the high-mountain region, that pastoral communities are receiving more benefits from the sale and use of non-timber forest products, particularly from the Himalayan fungus-caterpillar, known as Yarshagumba (Ophiocordyceps sinensis) which occurs in alpine rangeland regions. A study from the far western rangeland of the Alpine zone reported that average household cash income from O. sinensis was $2174USDper annum [46], which is greater than the total regular annual income of 90% of households in the region.
The above activities have brought about changes in the socioeconomic conditions of the mountain communities through awareness, increased education, and exposure to globalization, which has discouraged livestock farming in the mountain region. Adding to this was 10 years of Maoist armed conflict (from 1996 to 2006) in the country, which hit rural areas particularly hard. This resulted in youth migration to the cities or abroad in search of security and employment rather than staying in villages and farming. Hence, the effect of globalization in the mountain region has resulted in declining traditional pastoral systems due to changing societal values, disappearing customs, traditional values, weak social networks and institutions, and neglected common property management (i.e., rangeland). Several studies illustrate similar observations; changes in socioeconomic conditions have led to migration causing the decline of traditional pastoral systems and indigenous institutional arrangements in the Hindu Kush Himalaya [47][48][49].

Climate Change Impacts
Our field level consultation with herders and local communities reflects an increase in average temperatures over the past 8-10 years (Table 6). In some locations, however, local people reported unprecedented cold events including the month of May. The findings lead to the conclusion that the temperature in the Himalayan landscape has been steadily increasing, but the rate of increase varies across the regions. This correlates with the findings of The International Centre for Integrated Mountain Development (ICIMOD), which reports that as early as from 1901 to 2014, the annual mean surface air temperature has significantly increased in the HKH, at a rate of about 0.10 °C per decade (p> 0.05). Similarly, extremely cold days and nights have declined (0.85 and 2.40 days per decade, respectively), while occurrences of extreme warm days and nights have increased (1.26 and 2.54 days per decade, respectively). Warm nights have increased and days with frost decreased significantly throughout the region [1].
The Himalayan region and people are already vulnerable to natural disasters and economic shocks due to fragility, marginality, inaccessibility, and poverty [2]. Over the past decade, scholars have argued that global warming is a major concern in this region due to its impact on ecosystems and nature-based livelihood dependency of mountain and downstream communities [1,34,48,50]. It is reported that the warming trend is more pronounced at higher elevations with a steady annual warming trend ranging from 0.04 to 0.06 °C reported across Nepal [3,51]. The transhumance system is one of the traditional adaptation strategies to cope with climate variability in vulnerable communities. It is practiced as an adaptive approach to rangeland resource management, especially for livestock grazing in the high-mountain region. The local people's perceptions and scientific studies correlate with a warming climate in the mountain regions (Table 6).   However, some positive consequences of globalization were observed in the mountain region. The study found that socioeconomic conditions of the households queried have improved due to diversification of household income from off-farm business (e.g., tourism, hotel business, and remittance from abroad). Herders also reported an increase in market demand for sales of livestock, sheep, and goats, in urban centers, particularly during the Hindu festivals of Deshai and Tihar. There is also an increase in availability of feedstock grains and farm inputs for farmers due to improvements in rural road connectivity near remote villages. However, overall, there appears to be a decline in the sustainability of mountain farming systems that comes with this increased dependency on the market for purchasing inputs for agriculture, such as an increase in chemical fertilizer use rather than farmyard manure for crop production. Adding to this are local farm labor shortages and increased food insecurity [50]. Rangeland in the alpine region is also degrading due to unmanaged harvesting of non-timber forest products, particularly O. sinensis where large numbers of collectors litter rampantly.

This correlates with the findings of The International Centre for Integrated Mountain Development (ICIMOD), which reports that as early as from 1901 to 2014, the annual mean surface air temperature has significantly increased in the HKH, at a rate of about 0.10 • C per decade (p > 0.05). Similarly, extremely cold days and nights have declined (0.85 and 2.40 days per decade, respectively), while occurrences of extreme warm days and nights have increased (1.26 and 2.54 days per decade, respectively). Warm nights have increased and days with frost decreased significantly throughout the region [1].

It is reported that the warming trend is more pronounced at higher elevations with a steady annual warming trend ranging from 0.04 to 0.06 • C reported across Nepal [3,51]. The transhumance system is one of the traditional adaptation strategies to cope with climate variability in vulnerable communities. It is practiced as an adaptive approach to rangeland resource management, especially for livestock grazing in the high-mountain region. The local people's perceptions and scientific studies correlate with a warming climate in the mountain regions (Table 6).
Along with higher temperatures, herders indicated that more than 80 percent of the communities have experienced an increase in water stress due to decreased rainfall and a delay in the arrival of the monsoon rains by 15 to 20 days. Erratic rainfall, high-intensity storms, less or unpredictable snowfall, and frequent avalanches were other common observations of local people (Table 7). One of the Nomads from Upper Mustang explained, "It is very difficult for us to predict climate events. Over the last winter (2018), we were pounded with snow for two months and there was no grass to graze livestock and the Yaks began to starve, with nearly 30 yaks dying due to starvation in one of our families. We have not experienced it before".
This shows that there is increasing variability in precipitation patterns across the landscape, which coincides with findings from past studies; for example, there has been significant internal variability on annual and decadal time scales with climatic models predicting an increase in monsoon precipitation due to greenhouse-gas-induced warming [1,48,51,52].
Multiple stresses of rangeland resources from anthropogenic and climate change impacts, such as rising temperatures, reduced snowfall, and precipitation, has resulted in decreased biomass production and degradation of rangeland in the study areas. Furthermore, local herders also reported that increases in the unpredictability of heavy snowfall and avalanches have occasionally led to heavy losses of their livestock (Table 7). Bhatta and others [48] and Wester and others [1] also warn that warming in the Himalayan region could result in more rapid melting of snow cover and glaciers along with increasingly erratic rainfall and more frequent droughts leading to a decrease in regional ecosystem services. Aryal and others [34] make a case that climate variables could seriously affect marginalized transhumance communities due to their high dependency on rangeland resources, limited access to modern facilities, markets, and alternative incomes. Likewise, Dong and others [8] also noted that climate change/variability has propelled fragile pastoral agro-ecosystems into more a vulnerable state in the Himalayan region.
The above discussion and analysis reveal that over the past few decades, unprecedented changes have occurred in the patterns of resource use, developmental activities, and socioeconomic dynamics in the mountain regions of Nepal. These changes are generally influenced by geopolitical and policy changes, globalization and modernization, and associated socio-economic transformations within the society. This, coupled with a rapidly changing climate in the Himalayas, has large impacts the transhumance system in the region. Nonetheless, our analysis of the three major areas of the vulnerability of the pastoral systems of the mountain regions of Nepal suggest that non-climatic variables such as policy and globalization were more influential in eroding pastoralism as compared to climate change.

Adaptation Strategies
A variety of adaptation strategies have been adopted by pastoral communities in the mountain region of Nepal to protect their livelihoods. Various policies and programs from the government have also been provided to minimize the vulnerability of these pastoral communities. Hence, to overcome vulnerability and avert the risks arising from socioeconomic transformation, globalization, and climate change, households have adopted different strategies in the study area (Table 8). Furthermore, adaptation strategies can be grouped into categories that encompass mobility, land management, diversification, intensification, and storage in the changing contexts for securing livelihoods of the mountain dwellers. In this context, adaptation strategies have been implemented through policy/institutions both at the community and household levels in order to minimize risk and vulnerability of the pastoral communities as described in Table 9.

Conclusions
Our analysis revealed that despite the strong socio-economic and ecological significance of traditional pastoralism in the mountain region, it is in a transitional phase due to increasingly diverse challenges involving the herding system. The socio-economic changes, policy focus on establishing more conservation areas, and recentralization of local rights, combined with increasing impacts of climate change and risks of extreme weather events such as avalanches, heavy snowfall, intense storms, and drying water sources are contributing factors. These stressors are exacerbated by uncoordinated governmental policies and programs that have collectively contributed to the decline of the transhumance system in the high mountains of Nepal. It is not surprising that the hardships of herding, changing social values, pasture quality deterioration, and unclear policy and regulatory frameworks have all contributed to the growing decline in mountain pastoralism. It is our belief that the government programs and policy interventions for high-altitude pastoralism development have been inadequate to properly address the distinct socio-economic and ecological features of these mountain regions. In addition, increasing climate change impacts are causing increased uncertainty, thereby contributing to a declining interest and motivation among the new generation of herders to continue this occupation.
Several strategies will be needed if these trends are to be slowed or reversed. We recommend capacity enhancement and continuous facilitation for adaptation measures and coping strategies be provided to the herders as a priority action. It is hoped that these efforts will encourage and attract younger generations towards this occupation. Additionally, specific incentives considering the socio-economic drivers should be developed to sustain the local mountain economy. The traditional rights of mountain communities in the current forest and rangeland management policies have not been recognized and these must be addressed through appropriate policy reformulation. The effects of globalization on social and economic activities and changing lifestyles of the local communities are a particular threat to the wellbeing of youth in these communities. Thus, we recommend that local institutions should promote profit-oriented sustainable farming activities along with links to markets and associated value-added product development in order to minimize production risks for these mountain communities. Further research is needed in order to close the knowledge gaps related to location-specific issues in order to provide knowledge useful in future design and implementation of more effective policies and programs, which will lead to development of future healthy and resilient mountain economies.
