Complex global social-ecological challenges of our time such as climate change, biodiversity loss or, more recently, the Covid-19 pandemic can neither be comprehensively understood nor properly addressed by employing a single disciplinary or sectoral perspective. For this reason, more and more large inter- and transdisciplinary (ITD) initiatives are on the rise, intending to open up the silo-like production of knowledge and to advance the integration of different fields of expertise within academia, but also across science, policy and practice. While the need for ITD initiatives in order to both understand and address the complexity of such global socio-ecological challenges has increasingly been acknowledged by research institutions, funders and public authorities, a question remains concerning the extent to which prevailing conditions suffice for conducting ITD research, particularly in terms of whether the envisioned integration of perspectives and actors really happen in practice. This paper embraces a holistic view on ITD integration by presenting both an analytical framework and empirical insights from three ITD initiatives based in Switzerland dealing with sustainable urban water management, (future) extreme events and cross-sectoral climate impacts and climate services in different socio-economic contexts. The framework is based on critical realist reasoning and employs a structure-agency lens by distinguishing conditions of integration at different structural levels, while also acknowledging the power of actors to shape integration and the respective structures. The paper thereby illustrates and helps diagnose the source of challenges experienced in living up to ITD integration endeavors and how these different structural levels are interrelated and impact ITD integration. We conclude by discussing entry points for action aimed at transforming currently unfavorable structures into favorable ones. We thereby intend to provide, in particular, insights for a wide range of actors interested in making sure that ITD initiatives intended to address the global social-ecological challenges of our time can realize their full integration potential in practice.

Addressing climate inaction as our greatest threat to sustainable development

More than 1 degree of global warming has been reached and once projected impacts are now being realized. 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.

The argument that environmental stress is an important driver of migration has gained renewed attention amidst increasing climatic changes. 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 in situ or within close proximity.

“Sometimes, I just want to scream”: Institutional barriers limiting adaptive capacity and resilience to extreme events

Climate change is increasing atmospheric river risk, requiring communities to build resilience and implement adaptation strategies. 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.

Toxic trace elements (TEs) are commonly co-emitted with carbon dioxide (CO2) and pose challenges to achieving multiple Sustainable Development Goals (SDGs). However, the extent to which carbon mitigation measures can simultaneously reduce these pollutants remains unclear. Here, we developed an integrated assessment model to evaluate the impact of China’s carbon neutrality policies on TEs emissions from coal combustion across various regions and sectors. Our findings reveal that, compared to baseline scenarios, a 77% carbon reduction under the carbon neutrality policies leads to an 85%-88% decrease in TEs emissions in 2060 within coal-consuming sectors, highlighting the importance of regional and sectoral heterogeneity. We identified key regions and sectors with disproportionately high emission intensities and co-reduction potential. Priority regions include Shanxi, Inner Mongolia, Guizhou, Hubei, and Jiangsu, while critical sectors include petrol oil, power generation, services, chemicals, and metal smelting. We also portrayed, for the first time in literature, an integrated long-term roadmap for synergistic control of CO2 and TEs emissions. These findings provide valuable insights for optimizing multi-pollution reduction strategies and enhancing environmental governance efficacy.

Decarbonisation is progressing rapidly and different actors respond to its impacts in different ways. 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.
去碳化进程进展迅速,不同的参与者以不同的方式应对其影响。这些应对措施是为了抵制去碳化、适应新的现实,还是从根本上改变决定去碳化背景的社会和经济条件,取决于相关的行为群体以及他们能够利用的资源。本文通过盘点欧洲 11 个碳密集地区在转型过程中的应对措施,概述了不同行为群体在应对去碳化政策时所采用的各种 "应对策略"。利用报纸数据、地方层面的焦点小组和精英访谈,建立了一个包含 651 项应对措施的数据集。这些行动被分为 8 个主题和 34 个独立策略。这些策略揭示了广泛的回应。它们表明,抵制反应往往反映了尚未解决的不公正问题,许多政府专注于以可再生能源替代化石燃料的去碳化战略,而没有改变更广泛的社会经济条件,公众对更具变革性的战略有着广泛的需求,这些战略允许更深入的参与和代表,并重塑了谁能从能源系统重组中获益以及如何获益。

Aquatic food systems support global food and nutrition security, livelihoods, and economies, but put significant environmental pressure on the planet. 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.

The financialization of rivers: Clean Development Mechanism (CDM) subsidized hydropower in the Mekong Region’s basins at risk

The Kyoto Protocol’s Clean Development Mechanism (CDM) is a key carbon offset scheme that underpins the global carbon market. This mechanism leaves out many other non-carbon considerations, including the impacts of the CDM on water governance. The CDM produces credits primarily through energy projects and CDM funded hydropower is one of the most significant outcomes of nearly two decades of carbon financing with funding subsidizing over 1,000 large-scale dams. This research maps these rapidly built infrastructure projects in transboundary river systems, which has shown to have direct links to increasing hydropolitical tensions. 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.

京都议定书》的清洁发展机制(CDM)是支撑全球碳市场的主要碳抵消计划。该机制忽略了许多其他非碳因素,包括清洁发展机制对水资源治理的影响。清洁发展机制主要通过能源项目产生信用额度,而清洁发展机制资助的水力发电是近二十年碳融资的最重要成果之一,为 1000 多个大型水坝提供了资金补贴。这项研究描绘了这些在跨境河流系统中快速建设的基础设施项目,研究表明,这些项目与日益紧张的水文政治局势有着直接联系。湄公河地区的伊洛瓦底江、北江/西江、红河和萨尔温江都被认为是世界上冲突 "高危 "流域之一。我们的研究表明,这些 "极高风险 "河流是获得清洁发展机制资助的大型水电项目最多的四个流域。这四个 "极高风险 "流域和湄公河是 274 座清洁发展机制补贴大型水坝的前五大受援河流。这些大坝以中国和欧洲的碳减排要求为名在上游流域迅速融资和建设。这种应对气候变化的措施加剧了权力失衡,并增加了水文政治紧张局势的风险,因为湄公河流域的社区以欧洲和北京遥远的碳减排要求为名,承担着日益不安全的代价。

Inland fisheries face multiple, intensifying threats (i.e., proximate human pressures causing degraded ecological attributes) from land development, climate change, resource extraction, and competing demands for water resources. Planning for resiliency amidst these pressures requires understanding the factors that influence an inland fishery’s capacity to adapt to system changes under multiple threats. 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.
内陆渔业面临着来自土地开发、气候变化、资源开采和水资源竞争需求的多重、日益加剧的威胁(即造成生态属性退化的近距离人类压力)。在这些压力下规划弹性需要了解影响内陆渔业在多种威胁下适应系统变化能力的因素。结合专家知识可以阐明重点渔业,并在数据有限的情况下提供重要见解。利用对536名渔业专业人员的全球调查数据,本研究考察了主要内陆渔业对威胁和适应能力(即减轻或应对变化的能力)的看法。我们评估了29种不同感知威胁之间的关联及其排名影响得分,测试了五个适应能力域(即代理,资产,灵活性,学习,组织)之间的一致性,并检查了威胁与适应能力域之间的关系。结果提供了定量证据,表明内陆渔业面临的最大威胁来自渔业部门以外,而且大多数内陆渔业面临多重威胁。结果还支持这五个领域作为适应能力的集体衡量标准,并阐明了渔业面临的威胁与渔业适应能力之间的负相关关系。这些调查结果突出表明,渔业管理人员需要与非渔业部门(例如,多部门管理)一起参与决策,并优先考虑生境和流域尺度的保护和恢复工作,以提高生态转型中的适应能力。

African countries have been among the least historic producers of global carbon emissions, yet they are among the most vulnerable to and impacted by global climate change. 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. This introduction characterizes the impact of climate change on Africa; highlights each article’s key contributions and discusses implications of their findings in the context of electoral dynamics and climate policy discourse in Africa; and discusses some possible future directions for scholarship and policymaking on climate change in Africa.
非洲国家历来是全球碳排放最少的国家之一,但它们也是最容易受到全球气候变化影响的国家之一。气候变化正以多种方式深刻影响着非洲国家,包括加剧水资源紧张、破坏农业收成、影响生活方式、放大性别和其他方面的不平等。除了这些直接影响之外,气候变化的社会经济后果也正在影响非洲大陆的治理。由于目前的外债水平、快速城市化、社会不平等和农业用地压力,生活在农村贫困和非正式城市住区的人数继续增加。而后者中的许多人则经常面临洪水的危险,无法获得可持续的生计、饮用水、充足的食物、保健、电力、卫生和固体废物处理以及其他基本服务。气候变化加剧了整个非洲大陆内部和外部的人口流动;危及家庭和社区;威胁着非洲的生态、经济和政治稳定。政策制定者、从业者和其他利益相关者如何应对和适应当今非洲的气候相关威胁?本期特刊重点介绍了非洲学者和其他人在研究和质疑非洲应对气候变化的当前趋势、动态、政策和发展方面的工作。这七篇论文利用了多个层面的分析,从不同的学科角度出发,研究了非洲大陆不同国家与气候变化相关的成就和挑战。虽然这些文章通常质疑应对气候危机的政策,但大多数在框架和分析上都是具体的。这篇引言描述了气候变化对非洲的影响;强调每篇文章的主要贡献,并讨论其研究结果在非洲选举动态和气候政策话语背景下的影响;并讨论了关于非洲气候变化的学术研究和政策制定的一些可能的未来方向。
