Komi reindeer herding: the effects of socialist and post-socialist change on mobility and land use

This paper contributes to the discussion concerning the way in which Soviet state policies have influenced the lives, social organization, economy and culture of a group of indigenous Komi reindeer herders of northern Russia: its main focus is to explain how these policies have changed the herders' patterns of migration and land use. Extensive anthropological fieldwork—to determine current and past herding practices—was carried out and archives were thoroughly investigated to document land use changes in relation to state reindeer herding policies. It was found that compared with those of several decades ago, the migration routes are now much shorter, as the herders have abandoned large areas of winter pastures located in the southernmost part of their herding territory. This "abandonment" phenomenon is endemic amongst reindeer herders generally, throughout the Komi Republic. Whereas the reasons for the abandonment of winter pastures are diverse, they can be attributed mostly to the state sedentarization policy, which has modified the family structures of herders, and the continuing decreases in state subsidies that have changed the balance between state and private ownership of reindeer. Both these factors have greatly contributed to the herders' dependence on visiting towns, where they now own flats, and on selling reindeer products, upon which they are increasingly reliant for financial security.     

Land use and climate change on the Yamal Peninsula of north-west Siberia: some ecological and socio-economic implications

Compared to climate, land use change is expected to comprise a more important component of global change in the coming decades. However, climate is anticipated to supass land use as a factor later in the next century, particularly in the Arctic. Discussed here are the implications of land use and climate change on the Yamal peninsula of north-west Siberia, homeland of the Yamal Nenets. Since the discovery of super-giant natural gas fields in the 1960s, extensive exploration has resulted in direct withdrawal of large areas for infrastructure development and associated disturbance regimes have led to cumulative impacts on thousands of additional hectares of land. The land withdrawals have pushed a relatively consistent or increasing number of reindeer onto progressively smaller parcels of pasture. This has led to excessive grazing and trampling of lichens, bryophytes and shrubs and, in many areas, erosion of sandy soils via deflation. The low Arctic tundra lies entirely within the continuous permafrost zone and ice-rich substrates are widespread. One implication of this is that both anthropogenic and zoogenic distubance regimes may easily initiate thermokarst and aeolian rosion, leading to significant further losses of pastures. Even without industrial distubance, a slight change of the climate would result in massive thermokarst erosion. This would have negative consequences equal to or greater than the mechanical distubances described above. The synergistic effects of land use coupled with climate, change therefore have profound implication for the ecosystems of Yamal, as well as the future of the Nenets culture, society and economy.     

Reindeer in tundra ecosystems: the challenges of understanding system complexity

The resilience of tundra ecosystems is limited, with relatively few key biotic components determining the general pattern of the dynamics of these systems. Sustainable use of reindeer pastures, which are natural tundra ecosystems, should take into account interactions within the whole complex of key components. Among the most important are the small herbivorous rodents. For example, during peak densities lemmings may reduce above-ground plant biomass by 50-70%. At the same time, rapid turnover of nutrients in the form of significant amounts of potassium, phosphorus and nitrogen that lemmings excrete in urine promotes vascular plant growth. It is concluded that these kinds of studies are essential for the sustainable management of Russia's grazing lands: 1) comparative studies of productivity, biological diversity and structure of plant communities under the different pressures exerted by the main groups of herbivorous animals (reindeer and small rodents), as well as under varying levels of industrial development; 2) studies of the direct and indirect effects of herbivorous mammals on biological turnover and energy flow within the system; 3) studies of the role of industrial contamination on the turnover of nutrients in tundra ecosystems.     

Status, directions and priorities of reindeer husbandry research in Sweden

Emerging out of small-scale reindeer farming, large-scale reindeer husbandry in Sweden and Norway was developed to counteract resource scarcity caused by depleted wild reindeer numbers and human population growth above what the former subsistence economy could sustain. Current numbers of reindeer are likely lower and fluctuate less than before wild reindeer were depleted and reindeer husbandry started on a large scale. Productivity is about 7-8 kg of meat per head in winter stock. Current problems arise from a multitude of circumstances, some of them related to the problems of practising a subsistence type of living in close connection with a modern industrialized society. Problems include: low production, typical for harsh conditions and use of an unimproved animal stock; the inability to support a modern standard of living solely from reindeer; the collective access to grazing grounds which makes internal management difficult; unclear legal rights resulting in conflicting interests with other land users and formal owners; and the relatively low number of people directly involved in reindeer husbandry. Possible long-term consequences are marginalization and the loss of land use rights, with negative consequences for the Saami as an indigenous people. Reindeer husbandry research addresses these problems by integrating human-ecological and socio-economic aspects with traditional natural science orientated research on reindeer husbandry problems. This research is funded by a multitude of sources. Independently of this, research is conducted on Saami life and culture in relation to reindeer husbandry at various universities, especially within social sciences and arts.     

High voltage transmission lines and their effect on reindeer: a research programme in progress

We review literature on high voltage transmission lines and their effect on wild reindeer ( Rangifer tarandus ) migration patterns and area use. We conclude that reliable knowledge is lacking on the effects of transmission lines on reindeer ecology. This condition relates to the lack of long-term monitoring of reindeer migration patterns in relation to existing lines. It is also related to the fact that nothing is known about hearing in reindeer (or any other deer species in Norway) in relation to transmission line noise, which is considered an obstacle for migrating reindeer.
We then outline a research programme that includes a laboratory study to determine the audiogram in reindeer and two field studies to examine the proximate effects of transmission lines - independently as well as combined with ambient environmental variables - on reindeer behaviour. The audiogram in two yearling male reindeer has been determined; this part of the study will be completed this year with the determination of a corresponding audiogram in two female yearlings. The behaviour study of domestic reindeer under high voltage transmission lines was completed in September 1999. The behaviour study of wild reindeer in the area crossed by a 420 kV power line will continue this year and its completion is anticipated in 2001.     

Reindeer husbandry/hunting in Russia in the past, present and future

The dynamic state of reindeer husbandry in northern Russia during the 20th century was studied as a basis for predicting the consequences of the current drastic changes taking place there. Similar forms and methods of reindeer husbandry were used with different frequencies and effectiveness throughout the century. In the future reindeer husbandry will conform to market requirements, landscape features and national traditions. In some areas, the more sophisticated methods of management developed in conjunction with large-scale, highly productive reindeer husbanry, could be lost and a subsistence economy, including hunting, could predominate.     

Trust Matters – Social Capital in Herding Cooperation in Finland

Reindeer herding is a nature-based livelihood of the indigenous Sámi people in northern parts of Europe and Russia. During the last decades, reindeer herding has become a more significant issue in the context of the market economy: the livelihood has transformed toward entrepreneurship, and the subsidies demand growth in the scale of herding. According to the national administration, the market values are highlighted. However, for herders, market economies are only one part of their livelihood. Another important part is their experience of reindeer herding as a way of life; for many reindeer herders trust in their livelihood and the social relations associated with their way of life are of equal or greater importance than economic aspects. In this paper, the role of social trust in the changing process of reindeer herding is discussed. Inherited tacit and cultural knowledge, as a part of social capital, strengthen reindeer herders’ experience of trust.     

Homeland Orientation of War-torn Diasporas: Remittances and Cultural Practices of Tamils and Somalis in Norway

Wild reindeer are under pressure from human development projects throughout their habitat. Norway is currently making a significant move to establish a new management model based on national reindeer regions and regional management plans. A focus on wild reindeer as a flagship species allows the species to be included as a broad conservation objective in complex land-use plans. The authors surveyed a representative sample of residents in the Rondane and Setesdal regions to examine their perceptions of the current status of reindeer and how management relates to other social and development issues. Local actors and institutions, including hunters, were perceived as more responsible and suited to make decisions about reindeer population sizes and management objectives than non-local actors. There was little local consensus on the role of human impacts on wild reindeer, and residents rated local knowledge higher than scientific knowledge for management purposes. Rondane residents attached more importance to reindeer than Setesdal residents, but the latter saw reindeer as more threatened by human development. New management approaches will need to take a social-ecological perspective and recognize that the inclusion of reindeer can enhance broader conservation goals at regional, national, and international levels, but may also escalate local social conflicts.     

A reindeer herder's perspective on caribou, weather and socio-economic change on the Seward Peninsula, Alaska

Non-climate variables shape vulnerability and adaptive capacity to climate change. Here, we describe how recent environmental and socio-economic developments have transformed reindeer herding and perceptions of weather on the Seward Peninsula, Alaska. The reindeer industry has shrunk considerably since the early 1990s, when the winter range of the Western Arctic Caribou Herd expanded, and over 17 000 reindeer mixed with migrating caribou and left the region. Socio-economic and environmental repercussions make the continuation of herding tenuous, and erode the ability of herders to cope with weather variability, among other perturbations. We present a case study of one herder's annual cycle, and juxtapose physical drivers of herding activities, including weather-station and herder observations of local weather variability, with socio-economic factors. There is an increased urgency to access and monitor reindeer with caribou present, but herding plans are constrained by lower economic returns and the need to spend more time in non-herding jobs. Although weather is a greater concern now for immediate herd access, standard weather data are largely irrelevant to the mechanics of herding, whereas variables pertaining to the timing of biotic events (e.g., synchrony of spring break-up and calving) and visibility are attributed to lost herding opportunities. Short-term responses to weather conditions stem from more long-term vulnerability associated with caribou presence, reduced herd size, difficulties affording snowmobile maintenance or crew assistance, and dwindling market opportunities. We emphasize the environmental and socio-economic interactions that affect vulnerability and adaptive capacity for modern herding.     

Response of reindeer and caribou to human activities

Petroleum and mineral exploration and extraction, hydroelectric development, atmospheric transport of contaminants, timber harvesting and tourism are increasing worldwide, especially in the Arctic. This development may adversely affect populations of reindeer/caribou ( Rangifer tarandus ) which are the basis of subsistence economies for northern indigenous peoples. Our purpose is to present a survey of the literature that has investigated the response of reindeer/caribou to human activities. Individuals and groups of reindeer/caribou: 1) move away from point sources of disturbance; 2) increase activity and energy expenditure near disturbance; 3) delay crossing or fail to cross linear structures; 4) shift away from areas of extensive and intensive development; and 5) are killed by collisions with vehicles and by hunting along roads. Cows and calves during the calving season are the most easily disturbed group. Bulls in general and all reindeer/caribou during insect harassment are least likely to avoid development areas. Estimation of the proportion of a population that is exposed to disturbance and the implications of this exposure to annual energy budgets, survival and productivity of reindeer/caribou has received little attention. Future advances in understanding the implications of human disturbance to reindeer/caribou will require cumulative effects assessment at annual, population and regional scales. Although some level of cumulative effect is likely, clear separation of cumulative effects of development from natural variation in caribou habitat use and demography will be difficult.     

Chukotkan reindeer husbandry in the post-socialist transition

Reindeer herding in the Chukotka Autonomous Okrug, as in many other regions across the Russian North, has been experiencing a progressive collapse since the dissolution of the Soviet Union in 1991. The collapse is typically blamed on Russia's privatization programme, which broke up collectivized reindeer farms into supposedly privatized enterprises. While this process did indeed bring significant changes to the practice of reindeer herding in Chukotka, this paper argues that a more fundamental issue is the political and economic change at the local level that most likely makes the collapse irreversible. Áccording to the rhetoric of the new "democratic" framework, the majority rules, and their priorities take precedence. As a result, the indigenous peoples and their priorities - chief among which is reindeer herding - have been squeezed into the political margins. This has been exacerbated by the development of a relationship of internal colonialism between dominant urban Russians and village-dwelling indigenous reindeer herders, which has led to greater inequalities between the two groups as the Russians monopolize both resources and power in the region.

Regional effects of climate change on reindeer: a case study of the Muotkatunturi region in Finnish Lapland

Few studies have investigated current climate changes for high latitude regions, and the impact of such changes on reindeer and indigenous people. Previous work by other authors has identified snow and ice conditions in winter as being critical in determining the availability of forage for reindeer. Deep snow makes it difficult to access food. Lack of food weakens the herd and can reduce the allocation of nutrients to the development of the foetus in the female deer. Climate data for Lapland, northern Finland, and Karasjok, northern Norway, are examined, together with reindeer calf numbers for the period 1977 to 1994 for the Muotkatunturi region (68°N 25°30'E). Between 1883 and 1993, precipitation increased but temperatures showed no clear warming or cooling trend. However, since the late 1980s, temperatures have increased. A regression analysis on the climate and reindeer data found that the warmer the winter prior to the rut, the fewer the live calves recorded the following year (r = 0.529, p < 0.05). Also, the wetter the winter prior to the rut, the fewer the calves recorded (r = 0.427, p < 0.10). In contrast, the warmer the autumn prior to their birth, the greater the number of calves recorded (r = 0.474, p < 0.10). These results suggest that as climate changes and winters become warmer and wetter with increased snowfall, calf numbers will decline. These findings have important implications for the Saami people who are heavily dependent on the reindeer for their livelihood.     

Regulation of annual weight cycles in reindeer and other cervids

Seasonal changes in weight, food intake and metabolic rate are characteristic of reindeer and other northern ungulates. This article reviews relationships between endocrine and weight cycles in reindeer and other cervids, and the effect of manipulations with endocrine cycles upon the weight cycle. It appears that the secretions of most endocrine glands change throughout the year, either as a result of nutritional changes or of an inherent seasonal rhythm. It is suggested that the weight and metabolic cycles are secondary to an appetite cycle that is hormonally regulated. The hormonal control may include several hormones: sex steroids, thyroid hormones, and prolactin.     

Effects of weather and snow conditions on reproduction and survival of semi-domesticated reindeer (R. t. tarandus)

In this work we investigated the effects of local weather and snow conditions on the reproduction and survival of semi-domesticated reindeer ( Rangifer t. tarandus ) from 1962 to 1987 in four separate study areas in northern Finland. Reindeer density had no negative effect on calf percentage in slaughter (October-January) in any area. The higher the number of very warm days or mean temperatures in summer, the lower was the calf percentage in all forested areas (Sodankylä, Muonio and Ivalo). In the Muonio area, calf percentage was also reduced by winters with abundant snow accumulation. In the open, mountainous Kevo area, calf percentage was reduced with a high number of warm days (mean T>0°C) during the previous December. However, if the previous May was warm in that area, it had an opposite effect. High reindeer densities seemed to increase mortality only in the Sodankylä area. Abundant snow accumulation during winter reduced the survival index of reindeer both in the Sodankylä and Ivalo areas. In the Muonio area, mortality of reindeer was increased with a high number of warm days in December. In the Kevo area, reindeer density or any climatic parameters could not explain yearly differences in mortality. This study indicated that permanent changes in climatic conditions could have different impacts in woodland as opposed to open, mountainous regions. In general, if global climatic change means weather instability in early winter and more snow, it also brings more difficulties for reindeer. However, if climate change means that snow melts earlier in the spring, some conditions could become more favourable for reindeer.     

Rating the Degradation of Natural Hay Pastures in Northern China

Natural hay pastures in semi-arid pastoral areas produce the highest yields of hay in northern China. However, long-term continuous hay harvesting with no rest interval has resulted in severe degradation across widespread areas of these natural hay pastures. In addition, no clear data exist on the spatial distribution or degree of degradation occurring in natural hay pastures primarily because a nationally unified and normative evaluation standard is lacking. In view of the above problems, we employed an analytic hierarchy process to carry out screening and accuracy validation of evaluation indicators for natural hay pastures in north China grasslands (temperate meadow steppes, temperate steppes, mountain meadows, and lowland meadows). Our study identified seven easily measured indicators that reflect the state of natural hay pastures (average height, aboveground biomass, coverage, proportion of medium grasses, litter biomass, proportion of degradation-indicative plants, and proportion of bare spots and saline-alkali spots). A five-level scoring method was employed to delineate the threshold range for these indicators, The results of this study show that this method effectively solved the technical bottleneck for graded evaluation of degradation in natural hay pastures. This provides a theoretical basis for the scientific assessment of natural hay pasture degradation as well as important technical support for sustainable use of natural hay pastures and livestock production.     

Effects of substrate differences on water availability for Arctic lichens during the snow-free summers in the High Arctic glacier foreland

We used observational and experimental analyses to investigate the photosynthetic activity and water relationships of five lichen species attached to different substrates in a glacier foreland in the High Arctic, Ny-Ålesund, Svalbard (79°N) during the snow-free season in 2009 and 2010. After the rains ceased, lichens and their attached substrates quickly dried, whereas photosynthetic activity in the lichens decreased gradually. The in situ photosynthetic activity was estimated based on the relative electron transportation rate (rETR) in four fruticose lichens: Cetrariella delisei, Flavocetraria nivalis, Cladonia arbuscula ssp. mitis, and Cladonia pleurota. The rETR approached zero around noon, although the crustose lichen Ochrolechia frigida grown on biological soil crust (BSC) could acquire water from the BSC and retain its WC to perform positive photosynthesis. The light-rETR relationship curves of the five well-watered lichens were characterized into two types: shade-adapted with photoinhibition for the fruticose lichens, and light-adapted with no photoinhibition for O. frigida. The maximum rETR was expected to occur when they could acquire water from the surrounding air or from substrates during the desiccation period. Our results suggest that different species of Arctic lichens have different water availabilities due to their substrates and/or morphological characteristics, which affect their photosynthetic active periods during the summer.     

Rock-weathering by lichens in Antarctic: patterns and mechanisms

Saxicolous species of lichens are able to induce and accelerate weathering of their rock substrate, and effects of lichens on substrate can be attributed to both physical and chemical causes. This paper is focused on biotic weathering actions of epilithic and endolithic species on the different rock types (sandstones and volcanogenic rocks) in Antarctica. The patterns, mechanisms, processes and neoformations of rock-weathering resulting from lichen colonization are expounded in detail. Furthermore, it is pointed out that, for a better understanding of the impacts of lichens on environments, the studies on the rate of biotic weathering and the comprehensive involvement of the lichen effects on weathering of natural rocks remain to be carried out in Antarctica.     

Research planning in the face of change: the human role in reindeer/caribou systems

Reindeer/caribou ( Rangifer tarandus ) constitute a biological resource of vital importance to the physical and cultural survival of Arctic residents since time immemorial. Recent and possible future economic, social and ecological changes raise concern for sustainability of these resources and the well-being of those who depend on them. In February 1999 eighty scientists, reindeer/caribou users and resource managers gathered in Rovaniemi, Finland, for an interdisciplinary workshop to develop a circumpolar research plan that addressed the sustainability of humanreindeer/caribou systems. Small working groups addressed six themes: hunting systems, herding systems, rengeland/habitat protection, minimizing industrial impacts, maintaining the strength of indigenous cultures, and responding to global change. The resulting Research Plan cells for interdisciplinary comparative studies, advancement of tools for assessing cumulative effects, implementation of regional and a circumpolar monitoring and assessment programmes, and cultural studies on the transmission of knowledge. Cross-cutting directives for future research include:
• improving humans'ability to anticipate and respond to change;
• understanding better the dynamics of human-reindeer/caribou systems;
• developing research methods that are both more instructive and less intrusive;
• facilitating open communication among groups with interests in reindeer/caribou resources;
• organizing researchers into a strong, coordinated network;
• re-framing the conventional research paradigm to be more inclusive of differing cultural perspectives.
Three follow-up initiatives are proposed: 1) development of a web-based resource on the human role in reindeer/caribou systems (www.rangifer.net); establishment of a Profile of Herds database to support comparative research; and 3) convening of working groups to address specific problems identified by workshop participants.
