  • “Anyone Know What Species This Is?” – Twitter Conversations as Embryonic Citizen Science Communities
  • 2016
  • Ingår i: PLOS ONE. - 1932-6203. ; 11:3
  • Tidskriftsartikel (refereegranskat)abstract
    • Social media like blogs, micro-blogs or social networks are increasingly being investigated and employed to detect and predict trends for not only social and physical phenomena, but also to capture environmental information. Here we argue that opportunistic biodiversity observations published through Twitter represent one promising and until now unexplored example of such data mining. As we elaborate, it can contribute to real-time information to traditional ecological monitoring programmes including those sourced via citizen science activities. Using Twitter data collected for a generic assessment of social media data in ecological monitoring we investigated a sample of what we denote biodiversity observations with species determination requests (N = 191). These entail images posted as messages on the micro-blog service Twitter. As we show, these frequently trigger conversations leading to taxonomic determinations of those observations. All analysed Tweets were posted with species determination requests, which generated replies for 64% of Tweets, 86% of those contained at least one suggested determination, of which 76% were assessed as correct. All posted observations included or linked to images with the overall image quality categorised as satisfactory or better for 81% of the sample and leading to taxonomic determinations at the species level in 71% of provided determinations. We claim that the original message authors and conversation participants can be viewed as implicit or embryonic citizen science communities which have to offer valuable contributions both as an opportunistic data source in ecological monitoring as well as potential active contributors to citizen science programmes.

  • Governance, complexity, and resilience
  • 2010
  • Ingår i: Global Environmental Change. - Guildford, Surrey : Butterworth-Heinemann, publ. in cooperation with the United Nations. - 0959-3780 .- 1872-9495. ; 20:3, s. 363-368
  • Tidskriftsartikel (refereegranskat)abstract
    • This special issue brings together prominent scholars to explore novel multilevel governance challenges posed by the behavior of dynamic and complex social-ecological systems. Here we expand and investigate the emerging notion of “resilience” as a perspective for understanding how societies can cope with, and develop from, disturbances and change. As the contributions to the special issue illustrate, resilience thinking in its current form contains substantial normative and conceptual difficulties for the analysis of social systems. However, a resilience approach to governance issues also shows a great deal of promise as it enables a more refined understanding of the dynamics of rapid, interlinked and multiscale change. This potential should not be underestimated as institutions and decision-makers try to deal with converging trends of global interconnectedness and increasing pressure on social-ecological systems.

  • Our future in the Anthropocene biosphere
  • 2021
  • Ingår i: Ambio. - 0044-7447 .- 1654-7209. ; 50:4, s. 834-869
  • Tidskriftsartikel (refereegranskat)abstract
    • The COVID-19 pandemic has exposed an interconnected and tightly coupled globalized world in rapid change. This article sets the scientific stage for understanding and responding to such change for global sustainability and resilient societies. We provide a systemic overview of the current situation where people and nature are dynamically intertwined and embedded in the biosphere, placing shocks and extreme events as part of this dynamic; humanity has become the major force in shaping the future of the Earth system as a whole; and the scale and pace of the human dimension have caused climate change, rapid loss of biodiversity, growing inequalities, and loss of resilience to deal with uncertainty and surprise. Taken together, human actions are challenging the biosphere foundation for a prosperous development of civilizations. The Anthropocene reality-of rising system-wide turbulence-calls for transformative change towards sustainable futures. Emerging technologies, social innovations, broader shifts in cultural repertoires, as well as a diverse portfolio of active stewardship of human actions in support of a resilient biosphere are highlighted as essential parts of such transformations.

  • Reconnecting to the biosphere
  • 2011
  • Ingår i: Ambio. - : Springer Verlag (Germany). - 0044-7447 .- 1654-7209. ; 40:7, s. 719-738
  • Tidskriftsartikel (refereegranskat)abstract
    • Humanity has emerged as a major force in the operation of the biosphere, with a significant imprint on the Earth System, challenging social-ecological resilience. This new situation calls for a fundamental shift in perspectives, world views, and institutions. Human development and progress must be reconnected to the capacity of the biosphere and essential ecosystem services to be sustained. Governance challenges include a highly interconnected and faster world, cascading social-ecological interactions and planetary boundaries that create vulnerabilities but also opportunities for social-ecological change and transformation. Tipping points and thresholds highlight the importance of understanding and managing resilience. New modes of flexible governance are emerging. A central challenge is to reconnect these efforts to the changing preconditions for societal development as active stewards of the Earth System. We suggest that the Millennium Development Goals need to be reframed in such a planetary stewardship context combined with a call for a new social contract on global sustainability. The ongoing mind shift in human relations with Earth and its boundaries provides exciting opportunities for societal development in collaboration with the biosphere-a global sustainability agenda for humanity.

  • Transnational corporations and the challenge of biosphere stewardship
  • 2019
  • Ingår i: Nature Ecology & Evolution. - 2397-334X. ; 3:10, s. 1396-1403
  • Tidskriftsartikel (refereegranskat)abstract
    • Sustainability within planetary boundaries requires concerted action by individuals, governments, civil society and private actors. For the private sector, there is concern that the power exercised by transnational corporations generates, and is even central to, global environmental change. Here, we ask under which conditions transnational corporations could either hinder or promote a global shift towards sustainability. We show that a handful of transnational corporations have become a major force shaping the global intertwined system of people and planet. Transnational corporations in agriculture, forestry, seafood, cement, minerals and fossil energy cause environmental impacts and possess the ability to influence critical functions of the biosphere. We review evidence of current practices and identify six observed features of change towards 'corporate biosphere stewardship', with significant potential for upscaling. Actions by transnational corporations, if combined with effective public policies and improved governmental regulations, could substantially accelerate sustainability efforts.

  • The Transformative Imagination : Re-imagining the world towards sustainability
  • 2018
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • A central task for sustainability science in the Anthropocene is to offer guidance on alternative pathways of change. Even though this search and implementation of pathways towards sustainability is likely to require profound social-ecological transformations, little is yet known about the individual and collective capacities needed to support such transformations. This thesis explores the connection between human imagination and sustainability transformations, and introduces the notion of the transformative imagination to support methodological innovation in sustainability sciences, and practices aiming to support transformations towards sustainability. The transformative imagination is suggested to support fundamentally new ways of seeing, feeling, encountering and envisioning the world. The thesis takes a transdisciplinary action-research approach and studies how specific participatory practices, including the arts, may foster the transformative imagination as a means to more skilfully respond to, anticipate and shape social-ecological trajectories in the Anthropocene. The four included papers, each explores how practices may support particular features of the imagination as a transformative capacity. Paper I analyses a case in coastal Kenya where participatory modelling and future scenarios are applied to foster imagination of dynamics of interdependences and trade-offs within the context of poverty alleviation and ecosystems change. Paper II explores system diagrams and scenarios as practices for the development of social-ecological narratives that may support robust interventions in coastal Kenya and Mozambique. Paper III implements, and studies how an art-based approach based on performances, visual methods and an art installation, could support transformative visions of the Iberian Peninsula in the context of extreme climate change. Paper IV is a literature review of the potential contributions of the arts to transformations, in the context of climate change. These papers focus on different features of imagination, which under certain circumstances may progressively develop into societal transformative capacities with the potential to re-structure current social-ecological realities. Overall, this thesis is a step towards forging new kinds of reflexive, imaginative and deliberative practices that can support the emergence of local arrangements of a sustainable world where life can carry on.
