- Many traditional pastoralist systems are greatly impacted by cumulative encroachments of other land users and by climate change. Understanding land degradation and the adaptive capacity of people who are dependent on the rangelands is an urgent priority for many areas in the world. In this research we explore how changing environmental conditions affect herding strategies on winter pastures and the role of indigenous and local traditional knowledge (ILK) in Sami reindeer husbandry. Our results indicate that traditional Sami reindeer herding strategies are still practiced, but that rapidly changing environmental circumstances are forcing herders into uncharted territories where these traditional strategies and the transmission of knowledge between generations may be of limited use. For example, rotational grazing is no longer possible as all pastures are being used, and changes in climate result in unpredictable weather patterns unknown to earlier generations.

- Fennoscandian reindeer husbandry represents ecological, social-economical and institutional gradients reflected in different adaptations and management regimes. This provides for an interdisciplinary comparative research approach, between and within countries. By integrating perspectives from natural and social sciences, ReiGN engages in (1) identifying key drivers, (2) their effects on this pastoral system, and (3) how they are linked to ecological, social and political differences. In this chapter we outline the main challenges confronting this diverse and dynamic social-ecological system within a globalization and climate change perspective. This enables us to evaluate its adaptive capacities as well as its potential to stimulate policy decisions, societal responses and management actions for a viable reindeer husbandry. In this chapter we present reindeer husbandry in a historical context and introduce key concepts of Sámi reindeer husbandry to ease the understanding of our findings presented and discussed. We also offer an overview of the main research areas in which the ReiGN NCoE has conducted its work over the past several years.

Bokkapitel (refereegranskat)abstract
- This introductory chapter presents reindeer pastoralism as a social-ecological system and outlines its essential components. Reindeer herders – the pastoralists of the north, the reindeer and the natural environment of Fennoscandia – are briefly introduced. The chapter describes how different historical, natural and social environments lead to different management forms in Finland, Norway and Sweden. Further, it provides a historical overview of reindeer pastoralism deeply embedded in Sámi and local culture and gives some key statistics of the situation today. Finally, it outlines the major challenges that reindeer pastoralism is facing today within the three Fennoscandian countries. This chapter therefore provides the background for the detailed analyses in the main part of this book.

Pastures under pressure : Effects of other land users and the environment

Bokkapitel (refereegranskat)abstract
- Reindeer husbandry has a long history of sharing landscapes with a multitude of other forms of land use. By competing for space, industrial resource developments from the early 20th century onwards have affected where, when and how the landscape can be used for reindeer grazing. Extending from the local to the landscape level, these impacts can reduce pastures either directly or indirectly as a result of increasing landscape fragmentation or changing reindeer behaviour. Furthermore, environmental drivers influence the dynamics of forage availability or accessibility for reindeer. The observed trend of shrinking pastures in the three countries is caused by these cumulative impacts. As a consequence, grazing pressure on the remaining pastures increases, and it curtails reindeer herders’ options to respond to the challenges of climate change. Reversing the continuing decrease in pastures requires the restoration of grazing resources and increasing landscape connectivity to facilitate movement and grazing rotation. However, socio-political incentives are also required to sustain reindeer pastures in the future. This includes an increase in the influence of reindeer herders on land use decisions and the inclusion of their traditional ecological knowledge of pasture management to identify alternative approaches to natural resource management.

Stand age and climate influence forest ecosystem service delivery and multifunctionality
- 2020
-
Ingår i: Environmental Research Letters. - : IOP Publishing. - 1748-9326. ; 15:9
-
Tidskriftsartikel (refereegranskat)abstract
- We examine how levels of multiple ecosystem services (ESs) change with succession in forests with different tree species composition. More specifically we ask how ecosystem age interacts with environmental conditions to regulate ES delivery. Using the nationwide Swedish forest inventory, comprising boreal and temperate regions, we investigated how levels of six provisioning, regulating, recreational, and/or cultural forest ESs changed with forest age (10-185 years) in stands of different tree species composition. We also tested whether the number of ESs delivered (i.e. multifunctionality) changed substantially with stand age, using different threshold levels for ES delivery. Accounting for environmental conditions and stand properties, we found that levels of single ESs changed with stand age. Tree biomass production usually peaked in young to medium aged stands. In contrast, production of berries and game, and services related to biodiversity, were typically highest in old stands (120-185 years). Consistent with this strong temporal tradeoff, multifunctionality at lower threshold levels increased with stand age in most monocultures and mixtures, with the highest multifunctionality being reached somewhere between 100 and 185 years, depending on tree species composition. This was not evident for the highest threshold ES level (the top-20%), however. Moreover, multifunctionality usually decreased with warmer climatic conditions, with the exception of spruce-pine-birch mixtures. Taken together, our results show that a reduced forest age, e.g. due to forestry targeting early harvest of stands, most likely would limit the delivery of several ESs valued by society and result in less multifunctional forests. To maintain the capacity of forests to deliver high levels of multiple ESs, the role of stand age and tree species composition should be considered in decisions on how to manage future forests.

Blood-based epigenetic estimators of chronological age in human adults using DNA methylation data from the Illumina MethylationEPIC array
- 2020
-
Ingår i: BMC Genomics. - : Springer Science and Business Media LLC. - 1471-2164. ; 21:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Epigenetic clocks have been recognized for their precise prediction of chronological age, age-related diseases, and all-cause mortality. Existing epigenetic clocks are based on CpGs from the Illumina HumanMethylation450 BeadChip (450 K) which has now been replaced by the latest platform, Illumina MethylationEPIC BeadChip (EPIC). Thus, it remains unclear to what extent EPIC contributes to increased precision and accuracy in the prediction of chronological age. Results: We developed three blood-based epigenetic clocks for human adults using EPIC-based DNA methylation (DNAm) data from the Norwegian Mother, Father and Child Cohort Study (MoBa) and the Gene Expression Omnibus (GEO) public repository: 1) an Adult Blood-based EPIC Clock (ABEC) trained on DNAm data from MoBa (n = 1592, age-span: 19 to 59 years), 2) an extended ABEC (eABEC) trained on DNAm data from MoBa and GEO (n = 2227, age-span: 18 to 88 years), and 3) a common ABEC (cABEC) trained on the same training set as eABEC but restricted to CpGs common to 450 K and EPIC. Our clocks showed high precision (Pearson correlation between chronological and epigenetic age (r) > 0.94) in independent cohorts, including GSE111165 (n = 15), GSE115278 (n = 108), GSE132203 (n = 795), and the Epigenetics in Pregnancy (EPIPREG) study of the STORK Groruddalen Cohort (n = 470). This high precision is unlikely due to the use of EPIC, but rather due to the large sample size of the training set. Conclusions: Our ABECs predicted adults’ chronological age precisely in independent cohorts. As EPIC is now the dominant platform for measuring DNAm, these clocks will be useful in further predictions of chronological age, age-related diseases, and mortality.

- The global challenges that humanity faces are addressed in various global agreements, such as the Paris Agreement and the Convention on Biological Diversity. However, all global goals require local implementation and must be locally accepted. Adaptation and transformation will claim large land resources, such as infrastructures, wind farms, mines and intense land use for bioenergy. This may exacerbate already existing conflict over land use and the rights to resources, not least in northern peripheral areas. Reindeer pastoralism is affected by all of these interwoven processes, which gives a need for more holistic regional land use planning. This chapter summarizes some of the factors that have contributed to a lack of such planning and points to the importance of including reindeer herders as ‘rightsholders’ and their traditional knowledge in a transition to a just and sustainable society.

Tipping points and regime shifts in reindeer husbandry : a systems approach
- 2022
-
Ingår i: Reindeer husbandry and global environmental change. - London : Routledge. - 9780367632670 - 9780367632687 - 9781003118565 ; , s. 265-277

Bokkapitel (refereegranskat)abstract
- This chapter addresses the challenges to reindeer husbandry in Fennoscandia from a systems perspective. Drawing on information in other chapters in this book, the specific focus is on so called tipping points, or abrupt changes in the coupled social-ecological system. Tipping points may occur when external drivers push a system to an alternative system state, characterized by different feedbacks than in the original state. Compared to ‘ideal’ or traditional reindeer husbandry, examples of alternative states include reliance on supplementary feeding to compensate for losses of pastures, fencing herds to provide protection from predation, becoming a meat-processing industry based on more centralized herding practices and a total loss of reindeer husbandry. All of these states are seen as undesirable by the herders. Reindeer husbandry, as it is currently practised, requires intact social-ecological relationships within the herding districts, as well as in their interaction with the external society. These system qualities need to be strengthened as they innately provide resilience, and will demand structural, institutional and legislative changes, but also discursive changes of how we imagine what sustainability is, and whether herders are treated as one of many stakeholders or as the rights holders that they really are according to the law.

Reindeer husbandry and global environmental change : pastoralism in Fennoscandia
- 2022
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- This volume offers a holistic understanding of the environmental and societal challenges that affect reindeer husbandry in Fennoscandia today.Reindeer husbandry is a livelihood with a long traditional heritage and cultural importance. Like many other pastoral societies, reindeer herders are confronted with significant challenges. Covering Norway, Sweden and Finland – three countries with many differences and similarities – this volume examines how reindeer husbandry is affected by and responds to global environmental change and resource extraction in boreal and arctic social- ecological systems. Beginning with an historical overview of reindeer husbandry, the volume analyses the realities of the present from different perspectives and disciplines. Genetics, behavioural ecology of reindeer, other forms of land use, pastoralists’ norms and knowledge, bio- economy and governance structures all set the stage for the complex internal and externally imposed dynamics within reindeer husbandry. In- depth analyses are devoted to particularly urgent challenges, such as land- use conflicts, climate change and predation, identified as having a high potential to shape the future pathways of the pastoral identity and productivity. These futures, with their risks and opportunities, are explored in the final section, offering a synthesis of the comparative approach between the three countries that runs as a recurring theme through the book. With its richness and depth, this volume contributes significantly to the understanding of the substantial impacts on pastoralist communities in northernmost Europe today, while highlighting viable pathways to maintaining reindeer husbandry for the future.This book will be of great interest to students and scholars of both the natural and social sciences who work on natural resource management, global environmental change, pastoralism, ecology, social- ecological systems, rangeland management and Indigenous studies.

High rates of short-term dynamics of forest ecosystem services
- 2021
-
Ingår i: Nature Sustainability. - : Nature Publishing Group. - 2398-9629. ; 4, s. 951-957
-
Tidskriftsartikel (refereegranskat)abstract
- Currently, the main tools for assessing and managing ecosystem services at large scales are maps providing snapshots of their potential supply. However, many ecosystems change over short timescales; thus, such maps soon become inaccurate. Here we show high rates of short-term dynamics of three key forest ecosystem services: wood production, bilberry production and topsoil carbon storage. Almost 85% of the coldspots and 65% of the hotspots for these services had changed into a different state over a ten-year period. Wood production showed higher rates of short-term dynamics than bilberry production and carbon storage. The high rates of dynamics mean that static snapshot ecosystem service maps provide limited information for assessing and managing multifunctional, dynamic landscapes, such as forests. We advocate that dynamic, spatially explicit tools to assess and manage ecosystem service dynamics be further developed and applied in post-2020 biodiversity and ecosystem service policy supporting frameworks.
