Despite these impacts and the short timeframe available to avoid further warming, climate inaction remains a major threat to sustainable development. In this article, we bring a renewed focus to the issue of climate inaction. We unpack the systemic market failure that underpins current climate action efforts globally and how by shifting focus to address inaction this could be overcome. We explore how climate policies are inadvertently allowing climate inaction to persist, why this is happening and how to address it. Central to our argument is that climate policies still draw too heavily on a neoclassical development paradigm, rather than reinvigorated industrial policy, resulting in market interventions that fail to address the scale and systemic nature of the climate action challenge. We therefore reorient climate policies towards addressing inaction as a systemic development challenge that demands a stronger role from the government. We conclude by proposing a market systems framework for guiding policymakers to better target the systemic nature of climate inaction and the threat it poses to sustainable development<em>.</em></div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"91 ","pages":"Article 102969"},"PeriodicalIF":8.6,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143094133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines whether and how two distinct environmental stressors influence migration aspirations among affected populations. Our analysis relies on two waves of original survey data of 1,594 households residing in 36 villages along the 250 km of the Jamuna River in Bangladesh, an area heavily impacted by floods and riverbank erosion. The results reveal that riverbank erosion – a long-term environmental event causing permanent destruction – increases aspirations for internal, permanent migration by about 15 percentage points, 4 to 6 months after the occurrence. In contrast, sudden and short-term events, like floods, which have a more temporary impact, do not affect migration aspirations. These results suggest that the type of environmental event shapes adaptation strategies, with migration emerging as a viable response to more severe and lasting events such as erosion. This entails important policy implications regarding the effects of climate change on future patterns of internal migration and highlights that most affected individuals prefer to adapt to environmental stress <em>in situ</em> or within close proximity.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"91 ","pages":"Article 102966"},"PeriodicalIF":8.6,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143094135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective infrastructure and emergency management are two adaptations required for communities to cope with, and respond to, acute impacts of climate-related extreme events. In 2021, Fraser Valley, British Columbia, Canada experienced an unprecedented, yet anticipated, atmospheric river that exceeded risk-mitigation infrastructure and emergency management capacity. We ask: if they knew, why were they not prepared? Through a review of strategic planning documents and a qualitative analysis of semi-structured, key actor interviews, we analyze the impact of adaptive capacity on adaptation implementation. Our findings demonstrate that institutional barriers limited adaptive capacity, stagnated adaptation implementation and, in consequence, existing infrastructure and emergency management were insufficient to prevent acute impacts during the event. Further discussion identified formal and informal institutions preventing adaptation implementation: Formally, hierarchical governance decreased community adaptive capacity and led to infrastructure deficit, while informally, development-driven decision-making overshadowed infrastructure mitigation and preparedness priorities. Historical anthropocentric decisions persisted through path dependencies, preventing resilient decision-making during a time of rapid change. Recommendations are made to address these barriers and empower communities to prepare for climate change. This research offers understanding on institutional barriers limiting adaptive capacity and, more generally, contributes to a growing body of research that elucidates why communities face climate change underprepared.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"91 ","pages":"Article 102967"},"PeriodicalIF":8.6,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143094136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whether these responses seek to resist decarbonisation, adapt to new realities, or fundamentally transform the social and economic conditions that define decarbonisation contexts depends on the actor groups in question and the resources they are able to draw upon. This paper provides an overview of the kinds of “coping strategies” used by different actor groups in response to decarbonisation policy by inventorying these responses across eleven European carbon intensive regions in transitions. Using newspaper data, local level focus groups and elite interviews, a data set of 651 responses was created. Actions were grouped into 8 themes and 34 discrete strategies. These strategies reveal a wide range of responses. They demonstrate that resistance responses often reflect unaddressed injustices, that many governments are focused on decarbonisation strategies that substitute renewables for fossil fuels without changing wider socioeconomic conditions, and that there is broad appetite on the part of publics for more transformative strategies that allow deeper participation and representation, and reshape who benefits, and how, from the reorganisation of energy systems.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"90 ","pages":"Article 102968"},"PeriodicalIF":8.6,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143180951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The United States (U.S.) is the world’s fourth largest consumer and the largest importer of aquatic food, which makes it a good case for studying aquatic food systems. Here, we estimate the energy use, greenhouse gas emissions (GHGe) and blue water use by species, production method, product form, and stage of the U.S. supply chain, while accounting for trade and food loss and waste. We identified wide variation across species for energy use (40.2 to 259.1 MJ/kg), GHGe (3.7 to 22.2 kg CO2 eq/kg), and blue water use (15.8 to 1,851 l/kg). Capture fisheries and aquaculture on average used similar amounts of energy per unit of edible aquatic food; however, aquaculture emitted 54 % more GHGe and consumed 784 % more blue water than capture fisheries, due to the high GHGe and blue water intensity of aquaculture feed. Products with the lowest energy use were canned, fresh, and frozen sockeye salmon, frozen pollock, and frozen catfish. Products with the lowest GHGe were canned, fresh, and frozen sockeye salmon, frozen pollock, canned and frozen tuna, and frozen Atlantic salmon, All wild caught species had significantly lower blue water use impacts than farmed products. The production stage had the largest environmental impacts, but measuring production alone would miss 64 % of the energy, 36 % of the GHGe, and 21 % of the blue water used in the remainder of the supply chain. The processing stage was an important contributor to resource use for species with energy and water efficient production practices. Aquatic food in the U.S. supply is lost and wasted at an overall rate of 23 %; lost and wasted seafood contains 22 % to 24 % of the embodied energy, GHGe, and blue water in aquatic food systems. Compared to findings identified in the literature, aquatic foods in this study were lower in GHGe than beef, had a range of GHGe that extended above and below pork and poultry, and had higher GHGe than most legumes, and nuts. Estimating the environmental impacts and food loss and waste in the U.S. aquatic food system can help identify opportunities to enhance sustainability and resilience and support science communication about lower-impact foods and dietary patterns.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"90 ","pages":"Article 102964"},"PeriodicalIF":8.6,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143180950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Mekong Region’s Irrawaddy, Bei Jiang/Hsi, Red, and Salween rivers are all considered to be amongst the world’s river basins considered ‘very high risk’ for conflict. Our research shows that these ‘very high risk’ rivers were the top four river basins to receive CDM funded large-scale hydropower. These four basins at ‘very high risk’ along with the Mekong River were the top five recipient rivers of 274 CDM subsidized large-scale dams. These dams were rapidly financed and constructed in the upstream catchments in the name of carbon reduction claims in China and Europe.

Incorporating expert knowledge can illuminate priority fisheries and provide important insights where data are otherwise limited. Using data from a global survey of 536 fishery professionals, this study examines perceptions of threats and adaptive capacity (i.e., ability to mitigate or respond to change) in major inland fisheries. We assessed associations across 29 different perceived threats and their ranked influence scores, tested agreement among five adaptive capacity domains (i.e., agency, assets, flexibility, learning, organization), and examined relationships between threats and adaptive capacity domains. Results provide quantitative evidence that the greatest threats to inland fisheries come from outside the fishing sector and that most inland fisheries face multiple threats. Results also support the five domains as a collective measure of adaptive capacity and illuminate a negative association between the threats to a fishery and a fishery’s adaptive capacity. These findings highlight the need for fishery managers to engage in decision making with non-fishery sectors (e.g., multi-sectoral management) and the prioritization of habitat and watershed-scale conservation and rehabilitation efforts for improved adaptability amidst ecological transformation.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"90 ","pages":"Article 102949"},"PeriodicalIF":8.6,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142759507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate change is profoundly impacting African countries in a multitude of ways including exacerbating water stress, damaging agricultural harvests, affecting lifestyles, and amplifying gender and other dimensions of inequality. Beyond such direct impacts, socio-economic consequences of climate change are impacting governance on the continent, as well. With current levels of external debt, rapid urbanization, social inequality, and pressures on agricultural land, the number of people living in rural poverty and informal urban settlements continues to rise. Many of the latter, in turn, are in constant danger of floods, and lack access to sustainable livelihoods, potable water, adequate food, health care, electricity, sanitary and solid waste disposal, and other fundamental services. Climate change exacerbates internal and external human mobility across the continent; endangers families and communities; and threatens African ecologies, economies, and political stability. How are policymakers, practitioners, and other stakeholders responding and adapting to climate-related threats in Africa today? This Special Issue highlights the work of African scholars and others in examining and interrogating current trends, dynamics, policies, and developments in response to climate change in Africa. The seven papers utilize multiple levels of analysis, draw from various disciplinary perspectives, and examine climate change related accomplishments and challenges of diverse countries across the continent. While these contributions generally interrogate the policy response to the climate crisis, most are specific in their framing and analysis.
