Earth system boundaries and Earth system justice: Sharing the ecospace

This is the author accepted manuscriptThe literature on planetary and Earth system boundaries calls on humans to live within those boundaries. Sharing such limited ecospace raises questions of justice. Global environmental assessments and scholarship are increasingly paying attention to justice issues, yet inadequately define how to share the limited ecospace. Against this background we ask: how can global environmental assessments’ concerns for justice be enhanced through an Earth system justice (ESJ) framework that guides how the global community could share and flourish within the limited ecospace? Based on an analysis of how justice concerns are addressed in the Assessment of Assessments and global environmental change projects, we build an Earth system justice framework that discusses how ecospace can be shared fairly through the setting of Earth system boundaries and the provision of minimum resource needs for all, and how this can be achieved through an equitable redistribution of resources, rights, and responsibilities focused on addressing inequality, overconsumption, and harmful accumulation.Rockefeller Philanthropy AdvisorsEuropean Research Counci

Beyond climate-smart agriculture: toward safe operating spaces for global food systems

Agriculture is considered to be “climate-smart” when it contributes to increasing food security, adaptation and mitigation in a sustainable way. This new concept now dominates current discussions in agricultural development because of its capacity to unite the agendas of the agriculture, development and climate change communities under one brand. In this opinion piece authored by scientists from a variety of international agricultural and climate research communities, we argue that the concept needs to be evaluated critically because the relationship between the three dimensions is poorly understood, such that practically any improved agricultural practice can be considered climate-smart. This lack of clarity may have contributed to the broad appeal of the concept. From the understanding that we must hold ourselves accountable to demonstrably better meet human needs in the short and long term within foreseeable local and planetary limits, we develop a conceptualization of climate-smart agriculture as agriculture that can be shown to bring us closer to safe operating spaces for agricultural and food systems across spatial and temporal scales. Improvements in the management of agricultural systems that bring us significantly closer to safe operating spaces will require transformations in governance and use of our natural resources, underpinned by enabling political, social and economic conditions beyond incremental changes. Establishing scientifically credible indicators and metrics of long-term safe operating spaces in the context of a changing climate and growing social-ecological challenges is critical to creating the societal demand and political will required to motivate deep transformations. Answering questions on how the needed transformational change can be achieved will require actively setting and testing hypotheses to refine and characterize our concepts of safer spaces for social-ecological systems across scales. This effort will demand prioritizing key areas of innovation, such as (1) improved adaptive management and governance of social-ecological systems; (2) development of meaningful and relevant integrated indicators of social-ecological systems; (3) gathering of quality integrated data, information, knowledge and analytical tools for improved models and scenarios in time frames and at scales relevant for decision-making; and (4) establishment of legitimate and empowered science policy dialogues on local to international scales to facilitate decision making informed by metrics and indicators of safe operating spaces

Transcending unsustainable dichotomies in management: lessons from Sustainability-Oriented Hybrid Organisations in Barcelona

Transformations towards more sustainable consumption and production cannot be achieved through mainstream organisational management rationales and practices. These management rationales and practices tend to impose rigid, fictitious dichotomies between what occurs internally within the organisation and what occurs ‘out there’ in biophysical systems, economies, and the broader social world. Such abstract divides not only create strong limitations on organisations’ responsibilities to address the complexity of accelerated global change, but also further exacerbate unintended negative consequences on environmental sustainability. However, new organisational forms are emerging aimed at overcoming such split rationalities with the overall goal to couple in a more sustainable manner their daily organisational practices in relation to biophysical systems. In this inductive research, we ask how Sustainability-Oriented Hybrid Organisations (SOHOs) can successfully promote positive transformations towards sustainability. We analysed nine SOHOs in the Metropolitan Area of Barcelona and found that their transformative abilities relate to how they: (1) promote and apply complex socio-ecological worldviews where individuals and organisations are seen as integral components of socio-ecological systems; and (2) create enabling collaborative environments which include synergetic connections and substantive relationships ‘beyond’ the organisation. We found that the complexity of socio-ecological worldviews varies within the organisations which impacts the consistency to which they implement sustainability-related activities and experience mission drift

Positive tipping points in a rapidly warming world

The challenge of meeting the UNFCCC CoP21 goal of keeping global warming ‘well below 2 °C and to pursue efforts towards 1.5 °C’ (‘the 2–1.5 °C target’) calls for research efforts to better understand the opportunities and constraints for fundamental transformations in global systems dynamics which currently drive the unsustainable and inequitable use of the Earth's resources. To this end, this research reviews and introduces the notion of positive tipping points as emergent properties of systems–including both human capacities and structural conditions — which would allow the fast deployment of evolutionary-like transformative solutions to successfully tackle the present socio-climate quandary. Our research provides a simple procedural synthesis to help identify and coordinate the required agents’ capacities to implement transformative solutions aligned with such climate goal in different contexts. Our research shows how to identify the required capacities, conditions and potential policy interventions which could eventually lead to the emergence of positive tipping points in various social–ecological systems to address the 2–1.5 °C policy target. Our insights are based on the participatory downscaling of global Shared Socio-economic Pathways (SSPs) to Europe, the formulation of pathways of solutions within these scenarios and the results from an agent-based economic modelling
