'(Re)Defining ecosystems: A case study of the Colombian Páramo delimitations and shifting boundaries' by Alejandra Uribe-Albornoz & @julietalbot.bsky.social

doi.org/10.1002/geo2...
Screenshot of a paper abstract in Geo: Geography and Environment by Alejandra Uribe-Albornoz & Julie Talbot (2026) entitled: '(Re)Defining Ecosystems: A Case Study of the Colombian Páramo Delimitations and Shifting Boundaries' with an orange banner at the top. Ecosystems are inherently dynamic and so is our understanding of them. The concept of ecosystems has evolved over time, shaped by the cumulative effect of shifts in scientific paradigms, methodological advancements, environmental concerns and socio-political interests. This article examines how the Colombian páramos, a high-elevation mountain ecosystem, have been redefined multiple times through different delimitations, each reflecting a different scientific and methodological approach and resulting in different páramos distributions. Using a mixed-methods approach, we analysed how páramos have been conceptually and methodologically defined, exploring the actors and data that shape their boundaries. Then, we quantified the spatial transformations of the páramos between the different delimitations, identifying the areas where the páramo ecosystems expand and contract between delimitations as boundary shifts. Ultimately, this research enables us to examine how the concept of ecosystems is constructed through shifts in scientific paradigms and tensions between competing scientific and governance frameworks, revealing that ecosystem delimitation is not merely a conceptual exercise but an active process that reshapes and reconfigures landscapes.

'How to move from unjust to just transitions for renewable energy futures? Place-making and "unmaking" in the "left behind" coastal town of Blyth, Northumberland, UK' by Brett Cherry

doi.org/10.1002/geo2...
Screenshot of a paper abstract in Geo: Geography and Environment by Brett Cherry (2026) entitled: 'How to Move From Unjust to Just Transitions for Renewable Energy Futures? Place-Making and ‘Unmaking’ in the ‘Left Behind’ Coastal Town of Blyth, Northumberland, UK' with an orange banner at the top. Coastal towns with rich legacies of industry, technological innovation, and socio-technical infrastructures are in some cases prime locations for offshore wind energy transitions. However, some of these towns have been labelled as ‘left-behind’ due to the decline of coal mining and other high-carbon energy industries. This results in deep-seated impoverishment and socio-economic devastation for affected areas. This paper reports on research from the coastal town of Blyth, Northumberland in the North East of England. Blyth has a proud industrial heritage that has recently focused on cutting edge research and development of offshore wind technologies, and supply chains, for the UK's net zero energy transition. However, the research finds that to build a just transition co-produced with place-based communities requires new forms of collaboration (capacities) and place making that resonates with their values and assets. Otherwise, place-based interventions for net zero energy futures may be alienating for long-term residents, especially when coupled to forms of economic regeneration that may overlook or exclude marginalised voices. The multi-method approach of this study applies an assemblage theoretical framework that draws on in-depth interviews with community and industrial actors, ethnographic walks, go-alongs, asset mapping, and documentary analysis to highlight ‘possibility spaces’ for justice in a coastal town known for its community solidarity. The paper provides recommendations for how Blyth, and places like it, can enable marginalised community voices to co-produce local just transitions for the town and region, with implications for global justice.

'Qualifying coal: Materiality and the transformation of import supply chains in Poland' by Magdalena Dąbkowska

This paper is part of an ongoing Special Section on the 'Futures of Coal'.

doi.org/10.1002/geo2... #geosky
Screenshot of a paper abstract in Geo: Geography and Environment by Magdalena Dabkowska (2026) entitled: 'Qualifying Coal: Materiality and the Transformation of Import Supply Chains in Poland' with an orange banner at the top. While public debate has largely framed coal in terms of extraction and phase-out, less attention has been paid to its material properties and its role in shaping international supply chains. The 2022 embargo on Russian coal disrupted cross-border supplies, forcing importers and households to rely on new coal from overseas markets. Drawing on ethnographic fieldwork conducted between June 2022 and September 2023 in the Warmia region of northern Poland, this article examines how the need for specific coal parameters rendered some alternative supply routes viable while excluding others, thereby reshaping the import market. The arrival of unfamiliar coal varieties differing in moisture content, calorific value, grain size and combustion properties required evaluation of the new material and comparison with the old. The article shows how this evaluation extended beyond sites of exchange or practices of storage and use. Through processes of testing and comparison, coal is qualified as a tradable good. This qualification is distributed along supply chains, unfolding across sites of circulation rather than being confined to the product itself. By foregrounding the material differences and the practical work required to accommodate them, the qualification of coal sets in motion the transformation of import supply chains. The paper contributes to research on the materiality of energy and to studies of market qualification by showing how heterogeneity enables circulation, shaping which resource flows and logistics routes are rendered viable under conditions of disruption.

'Feeling environmental transitions in Nottingham: Love, social justice and place in the "Rebel City"' by Katie Keddie

This paper is part of an ongoing Special Section: 'Instrumentalising place-based approaches to urban energy transitions'.

doi.org/10.1002/geo2... #geosky
Screenshot of a paper abstract in Geo: Geography and Environment by Katie Keddie (2026) entitled: 'Feeling Environmental Transitions in Nottingham: Love, Social Justice and Place in the ‘Rebel City’' with an orange banner at the top. This paper explores the emotional and relational dimensions of place-based sustainability transitions using Nottingham as a key case study, grounded in its efforts to become the first carbon neutral city in the United Kingdom. Drawing on interviews, community workshops and participant observation, it examines how love—manifested through community care, place-based identity and collaborative practice—acts as a powerful yet contradictory force. Love can be a powerful motivator for environmental and social action whilst simultaneously generating inequalities and exclusion that threaten to undermine its transformative potential. The paper argues that for the city's climate strategy (CN28) to succeed, it must move beyond technocratic framings of transition and engage more deeply with the emotional infrastructures that shape how people relate to climate action in place. Love, here, is central to fostering just, inclusive and effective climate futures.

'Is understanding "fish as food" enough? Reclaiming power and politics in aquatic food research and policy' by @sophiestanden.bsky.social

This paper is part of an ongoing Special Section on sustainable food systems.

doi.org/10.1002/geo2... #geosky
Screenshot of a paper abstract in Geo: Geography and Environment by Sophie Standen (2026) entitled: 'Is Understanding ‘Fish as Food’ Enough? Reclaiming Power and Politics in Aquatic Food Research and Policy' with an orange banner at the top. Fish are an important source of food, livelihood and culture for millions of people worldwide. Yet, policy, research and fisheries management paradigms have not often recognised fish as food. Instead, fish are commonly viewed as a commoditised natural resource for economic development and fishing as a livelihood of last resort. However, in academic research and in some policy and fisheries governance circles, understandings of the importance of fish as food are increasing. This paper explores how understandings of fish as food have evolved in research, policy and governance. It shows that fish are most commonly articulated as food through the framing of food security. Through highlighting research gaps and limitations to securitised approaches to aquatic food systems and fisheries, it argues that a critical power-sensitive research agenda needs to be better engaged with in current ‘fish as food’ debates and discourse. Overall, this paper will review our understanding of the burgeoning push for conceptualising fish as food in policy, research and governance to identify gaps in our understanding and thus potential future areas for research.
