KEYWORDS: Eastern Pamirs, Tajikistan, solar energy potential, photovoltaics, high-mountain regions, radiation model, alternative energy resources, reduction of vegetation degradation, carbon emission savings
Peripheral mountain areas in developing countries are often characterized by energy poverty but also by high solar energy potential. The Eastern Pamirs of Tajikistan are a prime example of this situation, with their lack of energy infrastructure, remoteness, pressure on local natural resources, and high incident radiation amounts. An integrative assessment of the potential for photovoltaic power generation is lacking for this region, as well as for many other mountain environments. We assessed the natural potential, feasibility, and likely effects of increased photovoltaic electricity generation, using climate data, biomass data, a spatial radiation model, and fieldwork- and literature-based scenarios of energy requirements and financial conditions. Results indicated that using a photovoltaic power plant to generate enough energy for boiling water is feasible in the study area within reasonable cost limits. This could significantly alleviate energy poverty, increase carbon sequestration by up to 1500 t/y, and reduce the loss of dwarf shrub stands by up to 2000 ha/y. Our results illustrate that the integrative approach presented in this article can be applied straightforwardly when some climatic measurements and field observations are available and that photovoltaic energy is an important renewable-energy resource for the sustainable development of peripheral high-mountain communities.
Mountain regions are generally seen as depopulating. However, in the European Alps, a new migration trend can be observed that may represent a reversal of out-migration from these regions. The in-migration of so-called new highlanders brings people from lowland urban and peri-urban areas to mountain regions to live and work. Research on the economic and social contributions of these new highlanders is sparse, and there are no studies that focus on their entrepreneurial activities. This study examined the characteristics and contributions of new highlander entrepreneurs and found that they are unlike traditional amenity migrants who migrate because of quality of life. New highlander entrepreneurs migrate not only for quality of life reasons, they moreover follow business opportunities and contribute to the economic and social life of their chosen locations. Based on attributes such as personal circumstances, recognition and exploitation of opportunities, business strategies, and economic and social contributions, we grouped new highlander entrepreneurs into 4 categories and explored their reasons for migrating and other characteristics. We conclude that mountain regions represent viable locations for entrepreneurs, despite the many disadvantages associated with this peripheral context.
Agriculture is a minor contributor to local economies in European mountain and fjord areas where tourism is predominant; however, it is essential to maintain the agricultural landscape and other important nonmarket functions of mountain agroecosystems. Policy-makers have aimed to support agriculture in these areas, but farmers' perspectives are poorly understood. The purpose of this study was to analyze (1) the main characteristics of livestock farming systems and the recent changes they have undergone, (2) farmers' perceptions of different functions of agriculture, (3) farmers' goals, and (4) the relationships among these elements in order to support more targeted policy-making in fjord and mountain areas in Scandinavian countries. We collected data from 27 farms and conducted univariate and multivariate (principal components and cluster) analyses. Most recent changes in farming have been related to improving working conditions and increasing tourist activity. According to the farmers, the main nonmarket functions of agriculture were (1) maintaining cultural heritage and rural development, (2) delivering environmental services, and (3) promoting traditional agriculture. The farmers' primary goals were (1) innovating for better farming, (2) improving the family's quality of life, and (3) achieving economic objectives. We identified 2 clusters of farmers based on divergent perceptions of rural development and the goal of improving the family's quality of life. These results point to the importance of integrated policies that address agricultural, environmental, and rural development together and take into account farmers' diverse perceptions and goals.
Large cardamom (Amomum subulatum) is an economically valuable, ecologically adaptive, and agro-climatically suitable perennial cash crop grown under tree shade in the eastern Himalayas. In Sikkim, India, the focus of this study, large-cardamom production peaked early in the 21st century, making India the largest producer in the world, but dropped sharply after 2004; Nepal is now the largest producer. This crop is an important part of the local economy, contributing on average 29.2% of the income of households participating in this study. Farmers and extension agencies have worked to reverse its decline since 2007, and thus, there is a steady increase in production and production area. After reviewing the literature, we carried out extensive field research in 6 locations in Sikkim in 2011–2013 to investigate the causes of this decline and measures being undertaken to reverse it, using a combination of rapid rural appraisal, participatory rural appraisal, structured questionnaire, and field sampling techniques. Study participants attributed the decline in large-cardamom farming to 4 broad types of drivers: biological, socioeconomic, institutional/governance-related, and environmental/climate-change-related. Altered seasons, erratic or scanty rainfall, prolonged dry spells, temperature increase, soil moisture loss, and increasing instances of diseases and pests were prominent factors of climate change in the study region. Multistakeholder analysis revealed that development and implementation of people-centered policy that duly recognizes local knowledge, development of disease-free planting materials, training, subsidies, and improved irrigation facilities are central to improving cardamom farming and building socioeconomic and ecological resilience.
Land use and land cover (LULC) changes that occurred during 1992–2011 in Sagarmatha National Park, a United Nations Educational, Scientific, and Cultural Organization World Heritage Site in the Himalayas of eastern Nepal, were evaluated using multitemporal satellite imagery in combination with land use data and sociological information gathered from semistructured interviews and workshops. We asked study participants about LULC changes, the causes of each change, and the likely duration of its effects, and used this information to produce high-resolution maps of local perceptions of LULC change. Satellite image analysis revealed that above 6000 m there has been a decrease in the area covered by snow and ice and a consequent expansion of glacial lakes and areas covered by rock and soil. Between 3000 and 6000 m, forest and farmland are decreasing, and areas under grazing, settlement, and shrubland are increasing. Such LULC changes within the protected area clearly indicate the prevailing danger of land degradation. Results from the interviews and workshops suggest that people tended to detect LULC change that was acute and direct, but were less aware of slower changes that could be identified by satellite imagery analysis. Most study participants said that land use changes were a result of rapid economic development and the consequent pressure on natural resources, especially in the tourism industry and especially below 6000 m elevation, as well as limitations to protected area management and a period of civil war. Human influence coupled with climate change may explain the changes at higher elevations, whereas anthropogenic activities are solely responsible in lower areas. Although global factors cannot be mitigated locally, many of the local drivers of LULC change could be addressed with improved management practices that aid local conservation and development in this high mountain ecosystem. A broader interdisciplinary approach to LULC change should include a mix of satellite image analysis and local observations.
Livestock herding is a widespread practice in the mountains of Nepal, and grazing in the forest and pastures within protected areas is a main source of cattle fodder. Given the implications of grazing on biodiversity conservation and the need for sustainable management of pastures in the Manaslu Conservation Area of Nepal, we assessed grazing intensity along an elevational gradient following the Budhi Gandaki valley. The data set consisted of grazing intensities recorded every 250 m along a transect from 1400 to 5200 m above sea level and farmer interviews, after an initial satellite data analysis. Grazing and herd size were found to increase with increasing elevation, reflecting local livelihood dependency on cattle herding. Species richness was then analyzed along a grazing disturbance gradient at 7 goths (summer cattle shed) in heavily grazed areas. Disturbance was found to be moderate at intermediate distances, where species richness was found to be higher; the results agree with the generally accepted intermediate-disturbance hypothesis. The plant species not affected, even at the locations with highest grazing, were unpalatable species. These results can be useful in decision making related to management of forests and pastures in the Manaslu Conservation Area as well as in Himalayan forests and grasslands in general.
Swidden farmers are rapidly transitioning to other types of land use. This study was conducted in 2 villages (T village and P village) in southern Chin State, Myanmar. The number of swidden-cultivating households decreased by 50% in T village over 2003–2013, and varied over 2004–2013 in P village; 21% and 13% of the total population in T and P villages, respectively, have out-migrated for employment. In addition, the introduction of terrace farming, development of animal husbandry, marketing of non-timber forest products, and other activities that generate cash income have reduced dependency on swidden agriculture. Remittances from out-migrated family members also contribute significantly to household incomes. As a result, the area devoted to swidden agriculture has decreased. By establishing site-specific allometries and applying best-fit allometry coefficients, total aboveground biomass was estimated for both villages. Generally, the aboveground biomass increased with the age of the fallow. Out-migration, insufficient crop productivity, and the development of alternative income sources resulted in the decrease in swidden agriculture in the areas studied. Further biomass regrowth can be expected in both villages in the future.
This study quantified the effect of environmental variables on plant species composition in the Peochar Valley, located in the Hindu Raj mountains of the Hindu Kush. A mixture of quadrat and transect methods were used. Quadrat sizes were 10 × 10 m, 2 × 5 m, and 1 m2 for trees, shrubs, and herbs, respectively, determined using the minimal area method. Twenty-seven stations were established along 6 elevation transects on slopes with various aspects. Density, cover, and frequency were recorded for all species in each quadrat. Aspect, elevation, rock types, soil nature, and grazing pressure were also considered as edaphic and topographic variables. Preliminary results showed that the Peochar Valley hosts 120 species. Presence/absence data for these species were analyzed with cluster and 2-way cluster techniques to elaborate species composition in the study area; this resulted in 4 plant communities. Species abundance and environmental data matrices were developed to evaluate the ecological gradient of vegetation through canonical correspondence analysis. Of the environmental variables, elevation, aspect, grazing pressure, soil depth, and rock type showed a significant effect on species composition and diversity. We also identified the dominant and rare plant species in each plant community based on their low importance value indexes. Conservation measures are recommended for all flora of this valley and for rare species in particular.
Montane habitats are characterized by high variation of environmental factors within small geographic ranges, which offers opportunities to explore how forest assemblages respond to changes in environmental conditions. Understanding the distributional transition of adult trees and seedlings will provide insight into the fate of forest biodiversity in response to future climate change. We investigated the elevational distribution of 156 species of adult trees and 152 species of seedlings in a tropical montane forest in Xishuangbanna, southwest China. Adult trees and seedlings were surveyed within 5 replicate plots established at each of 4 elevational bands (800, 1000, 1200, and 1400 m above sea level). We found that species richness of both adult trees and seedlings changed with elevation, showing a notable decline in diversity values from 1000 to 1200 m. Tree species composition also demonstrated distinct differences between 1000 and 1200 m, marking the division between tropical seasonal rain forest (800 and 1000 m) and tropical montane evergreen broad-leaved forest (1200 and 1400 m). The results suggested that soil moisture and temperature regimes were associated with elevational distribution of tree species in this region. We also observed that seedlings from certain species found at high elevations were also distributed in low-elevation zones, but no seedlings of species from low elevations were distributed in high-elevation zones. The increase in temperature and droughts predicted for this region may result in the contraction of tropical seasonal rain forest at lower elevations and a downhill shift of higher tropical montane tree species.
The objective of this study was to determine a reliable and effective way to visually assess pastures under the site conditions that prevail in the Kyrgyz Republic, in particular the mountainous terrain. Such a method should make a visual evaluation of pasture conditions in the field possible and help build awareness among land users of soil and pasture degradation and the need for sustainable use of pasture areas. To this end, the Visual Soil Assessment (VSA) method was applied and verified in a research area in the Naryn district in the Kyrgyz Republic. This process included the application of 2 additional visual site assessment methods—the Muencheberg Soil Quality Rating and the method described in the Monitoring Manual for Summer Pastures in the Greater Caucasus in Azerbaijan by Etzold and Neudert in 2010, referred to subsequently as the MMSP method. A comparison of the VSA results to standard field measurements and laboratory-based analysis was also performed. The VSA method was found to be only moderately applicable under the site conditions, with low correlation between the indicator ratings and the results of the standard measurements. The MMSP method showed substantially better applicability. The results of the study suggest that further research is needed to refine the MMSP method to develop an effective visual assessment method that can be used to support sustainable use and protection of pasture areas in mountain regions.
Mountain ecosystems around the world are recognized to be among the most vulnerable to the impacts of climate change. The need to develop sound adaptation strategies in these areas is growing. Knowledge from the natural sciences has an important role to play in the development of adaptation strategies. However, the extent of and gaps in such knowledge have not been systematically investigated for mountain areas. This paper analyzes the status of knowledge from natural science disciplines and research needs relevant to the national and subnational climate adaptation policies of 1 US state (Washington) and 7 countries (Austria, Bhutan, Colombia, Germany, Nepal, Peru, and Switzerland), in particular the elements of those policies focused on mountain areas. In addition, we asked key individuals involved in drafting those policies to answer a short questionnaire. We found that research needs mainly concern impact and vulnerability assessments at regional and local levels, integrated assessments, and improved climate and socioeconomic data. These needs are often related to the challenges to data coverage and model performance in mountainous areas. In these areas, the base data are often riddled with gaps and uncertainties, making it particularly difficult to formulate adaptation strategies. In countries where data coverage is less of an issue, there is a tendency to explore quantitative forms of impact and vulnerability assessments. We highlight how the knowledge embedded in natural science disciplines is not always useful to address complex vulnerabilities in coupled human and natural systems and briefly refer to alternative pathways to adaptation in the form of no-regret, flexible, and adaptive management solutions. Finally, in recognition of the trans- and interdisciplinary nature of climate change adaptation, we raise the question of which knowledge production paradigms are best able to deliver sustainable adaptations to growing environmental stressors in mountain regions.
Mountain areas cover a significant proportion of the European continent. Within the European Union (EU), many of the newest Member States have particularly high proportions of mountainous land. Ongoing debates in the EU relate to perceptions of mountains as being “handicapped” or marginalized versus having specific development opportunities, and to the challenges of climate change and other global changes. In 2015 and 2016, these issues have been highlighted by the European Parliament and through the publication of a strategic research agenda by the Swiss–Austrian Alliance.
The Mountain Societies Research Institute (MSRI) conducts transdisciplinary research for development, with the goal of improving the livelihoods and well-being of mountain societies in Central Asia and building their resilience in a rapidly changing socioeconomic, political, and biophysical environment. MSRI is a core institute of the Graduate School of Development at the University of Central Asia (UCA), working alongside the Institute of Public Policy and Administration (IPPA). Beyond research, MSRI also engages in building Central Asian capacities to contribute to sustainable mountain development; serves as a knowledge hub for scholars, development practitioners, and policy-makers; and contributes to the development of UCA's academic programs, which will be offered in the Kyrgyz Republic, Tajikistan, and Kazakhstan.
The University is now ready to inaugurate its undergraduate program, with students coming from across Central Asia to its Naryn Campus in the Kyrgyz Republic in September 2016. MSRI is currently headquartered in Bishkek, Kyrgyz Republic, but, in the longer term, will be affiliated most closely with the Khorog Campus in Tajikistan, which is set to open in September 2017. MSRI will collaborate closely with UCA's Earth and Environmental Sciences Program, with contributions to teaching supported by innovative, applied research embedded in the University's Learning Landscapes initiative.
MSRI's development vision and research strategy are focused on addressing the multidimensional nature of current and anticipated changes in mountain areas of Central Asia and on building resilience in mountain societies.
Tucked in the foothills of the Maluti-Drakensberg Mountains is the Qwaqwa campus of the University of the Free State. This is the home of the Afromontane Research Unit, a multidisciplinary flagship unit addressing a largely under-researched area in South Africa.
