Introduction The science plan of the Terrestrial Flagship will focus on the recent rapid socio-ecological changes occurring in northerly regions, and will involve cross-cutting interdisciplinary research into climate effects on both natural and human systems. The recent persistent warming has caused dramatic changes in terrestrial arctic and sub-arctic regions, with continued loss of ice sheet and glacier mass, reduced snow extent and duration, increasing permafrost temperatures and a general “greening” of the Arctic (ACIA 2005, Serreze et al. 2007, 2009, Stroeve et al. 2008, SWIPA, 2011). The numerous ecosystem changes at high latitudes include the ravaging of sub-arctic forests by insect pest outbreaks (Sturm 2010) as well as the degradation of arctic tundra by erosion, increased runoff from land to water systems, and the encroachment by tall shrubs and trees into tundra landscapes which combine to shrink the areal extent of the biome (ACIA 2005). The functioning and biodiversity of tundra ecosystems, and their associated limnic ecosystems systems, is also impacted by changes in the cryosphere, although the precise implications of this are unclear as yet (Post et al. 2009). Endemic arctic species that have essential food web functions, as well as being highly valued by northern people, both as natural resources and as cultural icons, are already declining (McRae et al. 2010). At the same time, invasive species from the south are expanding into the high north (Chen et al. 2011). Recent rigorous scientific assessments of these changes, such as the Arctic Human Development Report (AHDR 2004); Arctic Climate Impact Assessment (ACIA 2005), Millenium Ecosystem Assessment (MEA 2005); IPCC (2007), NorACIA (Øseth 2010) and the forthcoming Arctic Biodiversity Assessment (ABA 2011) all draw compelling links to climate warming as the main cause. The serious implications of further warming of the Arctic mean that both ecosystems, and the people depending on them, face great challenges. The livelihoods and culture of northerly peoples are closely adapted to the natural world, and form an important basis for their general identity. Furthermore, climate changes at high latitudes have consequences far beyond the Arctic regions. Climate-induced changes in arctic ecosystems and landscapes feed back to the global climate system so as to accelerate warming at the global scale (Chapin et al. 2005, Swan et al. 2010, Schuur and Abbot 2011). A key message from scientists at the close of the International Polar Year (IPY) is that there are still crucial gaps in our understanding of the connections between climate change and the responses of ecosystems and human society (Post et al. 2009). One underlying reason for this is that basic understanding of the functioning of arctic ecosystems is limited. This constrains the ability to predict ecosystem resilience to external forcing, and thus to distinguish “normal” ecosystem dynamics from new states induced by climate change. A further important factor is that there is an urgent need to improve the ability to empirically document changes. This applies to both those changes that may be predicted by models and scenarios, as well as the surprises that arise from extreme events (pulses) or gradual climate change (presses) pushing non-linear ecological systems beyond tipping points. These challenges will best be met by establishing adaptive long-term monitoring systems (observatories). The design and implementation of these should be guided by robust models of system-functioning and state-of-the-art measurement technologies (Lindenmayer and Likens 2009, 2010). A third factor is that there is still limited knowledge concerning the combined impacts of climate and ecosystem changes on societies of the high north. There are a number of studies that have examined human adaptation to natural climate- and ecosystem-variations in the past (see e.g., Pfister and Brázdil 1999; Wigley et al. 1981, Ogilvie et al. 2009). However, although studies have also been undertaken regarding present- day climate impacts on societies and cultures (see e.g., Huntington et al. 2001, 2003, Gearheard et al. 2006, Hovelsrud and Smit 2010, Krupnik et al. 2010) much further research is required in order to establish to what extent future climatic and ecosystem regimes will require adaptations that are quite different from those used in the past. A further crucial element is that in order to identify valid options for mitigating and adapting to climate-change impacts in the context of management and governance systems, and for societies to be able to act on predictions and observations of climate impacts on 1 socio-ecological systems (see, e.g., Berkes and Folke 1998, Berkes et al. 2003) there is an urgent need for improved understanding of how management regimes work at different decision levels. The Terrestrial Flagship of the Fram Centre has as its mandate and primary goal to accept the key challenges to high-latitude climate-impact research detailed above, and, on the basis of high- quality cross-disciplinary research, to become an internationally-recognized leader in this field. This aim will be accomplished by excellence in research on: climate impacts on high latitude socio- ecological systems in order to advise policy makers, management bodies, local inhabitants, and other stakeholders as to how climate change and its associated impacts could be met by means of adaptations and mitigations. These tasks call for both a great deal of diversity and breadth in scientific approaches (Lindenmayer et al. 2010). We need to conduct path breaking natural and social science studies that allows for a deeper understanding of the functioning of northern nature and culture. Such basic disciplinary research will in turn provide robust foundations for projects with applied scopes and cross-disciplinary protocols. Finally, the applied research programs need to establish tight links between science and its users such as policy makers, managers, stakeholders and the interested general public. For this to be achieved outreach strategies must be developed and implemented. 2. Goals 2.1 Primary goal The flagship shall advance and build on scientific competence and collaboration within the Fram Centre in order to establish a dynamic programme that facilitates new knowledge concerning climate impacts on socio-ecological systems with a focus on high-latitude landscapes. 2.2 Secondary goals • The flagship shall identify climate-induced changes regarding vulnerable and essential aspects of high-latitude ecosystems, such as key ecosystem functions and services and arctic biodiversity, • develop knowledge and information concerning human vulnerability, resilience, sustainability and adaptive capacity in the context of climate change in the circumpolar north, • establish how governance and management regimes at different levels of organization can increase the adaptive capacity and resilience of high latitude socio-ecological systems, • develop theoretical and methodological approaches that facilitates cross-disciplinary research on socio-ecological responses to climate change in high latitude landscapes, and • strengthen the empirical basis for prediction and detection of climate-induced changes by developing and implementing adaptive monitoring-systems (observatories) in the Norwegian Arctic. 3. Deliverables Terrestrial Flagship research will be useful to local communities, management bodies, and other stakeholders for example by elucidating how provisional ecosystem services such as fish, game, livestock, and agricultural and land-use products will be impacted by climate change, and by exploring how prudent management strategies could potentially adapt to or mitigate such impacts. The Flagship will work with communities, management agencies, and other stakeholders and will establish a close dialogue in order to inform them of research results. This will include the identification of crucial trends and drivers regarding vulnerable northern socio-cultural values, arctic species and ecosystems. A major emphasis will be placed on the dissemination of all research results to a wide variety of audiences including researchers, management bodies, students at all levels, others stakeholders, and, in particular, the local communities to be studied.
