Locally led adaptation (LLA) has recently gained importance against top-down planning practices that often exclude the lived realities and priorities of local communities and create injustices at the local level. The promise of LLA is that adaptation would be defined, prioritised, designed, monitored, and evaluated by local communities themselves, enabling a shift in power to local stakeholders, resulting in more effective adaptation interventions. Critical reflections on the intersections of power and justice in LLA are, however, lacking. This article offers a nuanced understanding of the power and justice considerations required to make LLA useful for local communities and institutions, and to resolve the tensions between LLA and other development priorities. It also contributes to a further refinement of LLA methodologies and practices to better realise its promises. Ultimately, we argue that the utility of the LLA framing in promoting climate justice and empowering local actors needs to be tested empirically.

The removal of three perfluorinated carboxylic acids (PFCAs)-PFHpA, PFOA, and PFNA-in ultrapure and river water was evaluated using two anion-exchange resins-previously unreported macroporous polystyrenic A-500P and a more widely studied macroporous polyacrylic A-860. Both resins had similar properties, allowing direct comparison of PFCA removal performance between the two resin structures/matrices. This study also presents a new gas chromatography-mass spectrometry (GC/MS) method developed for PFCA analysis in water. In ultrapure water, A-500P exhibited higher removal capacity and faster removal compared to A-860, suggesting greater effectiveness of the polystyrenic structure compared to the polyacrylic structure. In the Grand River water, the target PFCAs were well removed by A-500P but not A-860. However, both resins achieved similarly high overall reductions of dissolved organic carbon (∼75%), suggesting, later confirmed in ultrapure water experiments, that inorganic anions (sulfate particularly) were the dominant competitors for the A-860 resin. The uncharged styrenic and acrylic beads (base materials) of the two tested resins were unable to remove PFOA, implying that the dominant removal mechanism involves charge interactions between the negatively charged PFCA and the positively charged anion-exchange functional groups.

Responding effectively to climate crisis requires strong science-policy links to be put in place. Past research on the research-policy interface indicates longstanding challenges that have become more acute in the case of climate science, since this requires multi-disciplinary approaches and faces distinctive political challenges in linking knowledge with policy. What can be learned from the experiences of university-based researchers seeking to influence policy as they try to operate in the brokering space? With this in mind, an empirical study was designed to capture the detailed views and experiences of forty researchers in four universities across four countries—Bangladesh, Germany, Uganda and UK. It found a wide range of different researcher attitudes to policy engagement, diverse methods of engaging, a preference for working with government and civil society over private sector policy actors, and a perceived need for more university support. The findings suggest a need to rethink conditions for engagement to create spaces for knowledge exchange and cooperation that can contribute to policies for societal transformation. More attention also needs to be paid to interdisciplinary research approaches, improving research connections with private sector actors, and strengthening university research links with local communities. Finally, the position of university based researchers in the Global South will require strengthening to improve North–South knowledge exchange, capacity development, and incentives for policy engagement.

Purpose: The purpose of the paper is to challenge and address the limitations of the traditional system of knowledge production that is embedded in disaster and climate change research studies, and research studies in general. It argues that knowledge production in research processes conforms to colonialist thinking or west-inspired approaches. Such a system often results in the omission of crucial information due to a lack of participation, inclusion and diversity in knowledge production.Design/methodology/approach: The paper proposes practices and recommendations to decolonise knowledge production in disaster and climate change research studies, and research studies in general. It provides a brief literature review on the concepts of decolonisation of knowledge and epistemological freedom, and its origins; assesses the need for knowledge decolonisation, emphasising on the integration of local knowledge from grassroots women-led initiatives in instances where disasters and crises are being investigated in vulnerable communities, especially in the Global South; and finally the paper proposes to decolonise knowledge production through activating co-learning and co-production. The practices have been developed from the work of relevant authors in the field and case studies.Findings: Through a brief literature review on previous discourses on the topic of knowledge decolonisation and analysis of recent case studies on disaster and crisis management and community resilience, the paper finds that there exists a lack of pluralism and inclusion in epistemology which limits the pursuit to obtain the whole truth in the production of knowledge in research studies.Originality/value: This paper adds to the discussion of decolonisation of knowledge in the field of disaster and climate change research studies, and research processes in general. It provides in-depth analyses of recent case studies of emerging community resilience and local practices that were crucial in the face of the coronavirus disease 2019 (COVID-19) crisis.
