- Cities and climate change: combining bibliometric trends and city-level evidence to understand the connections between urban resilience and adaptive capacityPublication . Leal Filho, Walter; Bichueti, Roberto Schoproni; Dinis, Maria Alzira Pimenta; Begum, Halima; O'Hare, Paul; Malakar, Krishna; Kouassi, Jean-Luc; Danumah, Jean HomianClimate change poses escalating challenges to urban systems, intensifying risks from extreme temperatures, flooding, sea-level rise, and socio-environmental inequalities. Cities are increasingly recognised as critical arenas for climate adaptation, where resilience and adaptive capacity shape the capacity to anticipate, absorb, and respond to climate-related impacts. This study maps research on urban resilience and adaptive capacity through a bibliometric analysis of Web of Science publications (2010–2023), identifying dominant thematic clusters via keyword co-occurrence and collaboration patterns via co-authorship networks. To connect research trends with practice, this study also reports on a qualitative meta-synthesis of twelve published city case studies from diverse geographic and socio-economic contexts. Explicitly linking bibliometric themes with city-level adaptation evidence, this study identifies areas of convergence (e.g., governance, nature-based solutions, and risk assessment) and persistent gaps, particularly in the operationalisation of social equity, participation, and maladaptation risks. The findings provide an integrated evidence base that may help inform future urban climate adaptation research and policy.
- Climate change, planetary health and education in Africa: some case studies and perspectivesPublication . Leal Filho, Walter; Djekic, Ilija; Matandirotya, Newton; Donkor, Felix Kwabena; Ibrahim, Umar; Mbih, Richard; Kateka, Adolphine; Roeseler, Jasmin; Sharifi, Ayyoob; Dinis, Maria Alzira PimentaAfrica is a diverse continent with a rich cultural heritage, abundant natural resources characterised by a great vulnerability to climate change and several health inequalities. These inequalities are also observed in the provision of planetary health instruction. This paper explores the interconnection between climate change and planetary health education inAfrican universities. Also,the study examines the extent to which some African universities are handling the theme of planetary health education. The method used involved a bibliometric analysis of climate change and health, focusing on specific institutions and initiatives that illustrate the extent of planetary health education carried out in Africa till date. The results of the study suggested that themes related to planetary health are increasingly being studied in African universities. Also, the study notes that the term “planetary health” is scarcely used in the reviewed literature; and to make planetary health a common topic in university programmes, the theme needs to be given a wider recognition and attention. The paper concludes by outlining measures that should be implemented as part of public health programmes to be offered at African universities, which may help in enhancing the adoption of education on planetary health.
- Decarbonising university operations: strategies and challenges for Higher Education InstitutionsPublication . Leal Filho, Walter; Aguiar, Alexandre de Oliveira e; Elahi, Muhammad Manzoor; Azam, Fardous Mohammad Safiul; Dinis, Maria Alzira Pimenta; Henrique, João Paulino Pires Eustachio; Mazhar, Muhammad Usman; Mazutti, Janaina; Gatto, Andrea; Etxano, Iker; Kounani, Aristea; Aina, Yusuf; Viota, MariaBackground: Universities have significant carbon emissions impact and face pressure to cut their operational carbon emissions around the world. This leads to growing interest of the academic and practice community in effective pathways for carbon reduction within higher education. In this context, the aim of the research is to investigate the strategies for decarbonising university operations and challenges being faced. Drawing from a mixed-method approach, a review of case studies, and a survey involving Higher Education Institutions (HEIs) in nearly 40 countries, it explores the interconnectedness of awareness, cultural and political dimensions, internal institutional structures, and technical approaches in achieving decarbonisation goals. Results: The findings underscore awareness initiatives that enhance understanding of decarbonisation among educators and students in universities, and communities. The case studies as a review of experiences from diverse geographical regions illustrate varying strategies for carbon emissions reduction in HEIs, underscoring the adaptability of decarbonisation efforts across contexts. Additionally, cultural and political factors emerge as key determinants, requiring tailored strategies to navigate diverse contexts and garner public support. Finally, institutional structures, including financial constraints and regulatory barriers, and ageing infraestructure are identified as key barriers to effective decarbonisation efforts. Conclusions: The novelty of the paper resides on the fact that it highlights the need for integrating decarbonisation goals into institutional governance and planning mechanisms is essential for achieving long-term goal of net zero carbon and aligning with the global UN Sustainable Development Goals (SDGs). The study advocates for a holistic approach that considers social, economic, environmental and institutional dimensions in advancing decarbonisation within HEIs, rather than treating emissions as a purely technical issue. The effectiveness of decarbonisation measures is dependent on breaking down chronic structural and financial factors in the implementation, and is substantially supported by institutional practices that promote the engagement of all stakeholders and an open, transparent measurement of its impact. By addressing barriers, HEIs can pave the way for a sustainable and low carbon future while serving as catalysts for broader societal change.
- Dinner is served: how climate change interferes with olive oil productionPublication . Leal Filho, Walter; Luetz, Johannes; Dinis, Maria Alzira Pimenta; Nagy, GustavoThe Mediterranean region accounts for nearly 95% of global olive oil production. However, climate change - manifesting in intensified heatwaves, prolonged droughts, and increased pest prevalence - is undermining both the quantity and quality of yields. These disruptions threaten the livelihoods of rural producers and destabilize international markets. This article examines the complexities facing growers and outlines targeted mitigation strategies, highlighting the broader implications of climate change for a staple commodity relied upon daily by millions around the world. The analysis highlights interconnected climate impacts on agriculture, trade, and gastronomy, and identifies opportunities to enhance resilience through policy, agronomic innovation, and sustainable practices. It advances an integrated approach to Mediterranean food sustainability, linking agricultural adaptation with culinary heritage.

- Is carbon dioxide removal in the Arctic region really feasible?Publication . Leal Filho, Walter; Luetz, Johannes; Dinis, Maria Alzira Pimenta; Hunt, Julian; Nagy, GustavoThe Arctic region, warming at nearly four times the global average rate, is both an important carbon sink and a potential source of greenhouse gas emissions, especially due to thawing permafrost. Carbon dioxide removal (CDR) is increasingly recognised as a necessary measure to support global efforts to reduce emissions. This article examines whether, and under what conditions, large-scale CDR deployment in the Arctic is practically feasible. It also discusses the challenges associated with it. We synthesise peer-reviewed evidence on the performance of key CDR approaches relevant to high-latitude environments, including nature-based solutions (NbS), e.g. peatland restoration, blue carbon protection and afforestation, as well as enhanced rock weathering (ERW), ocean alkalinity enhancement (OAE) and direct air carbon capture and storage (DACCS). Across these approaches, the feasibility is constrained by permafrost dynamics, hydrology, ecological sensitivity, energy availability, monitoring and verification, and governance. Whereas some CDR methods offer potential climate benefits, most are characterised by considerable uncertainty and context-dependent trade-offs. None currently demonstrates unequivocal feasibility at scale under Arctic conditions. Beyond these technical and ecological constraints, we identify four clusters of socio-political barriers that further complicate Arctic CDR: governance fragmentation, geopolitical tensions, inadequate regulatory mechanisms, and uneven global deployment. A comparative assessment suggests that peatland restoration and blue carbon protection are the most immediately actionable options, whereas DACCS and OAE would require substantial new infrastructure and energy investment. The study concludes by outlining targeted policy and research priorities to address existing technological, ecological, and governance challenges, and to situate Arctic CDR within broader mitigation strategies without risking over-reliance or mitigation deterrence. The novelty of this paper lies in its analysis of the multiple variables that influence the viability of CDR. Overall, Arctic CDR appears technically possible but remains highly constrained, with its feasibility contingent on meeting stringent operational conditions, robust governance, and continued emissions reductions elsewhere.
- Managing ecosystem services in the Brazilian Amazon: the influence of deforestation and forest degradation in the world’s largest rain forestPublication . Leal Filho, Walter; Dinis, Maria Alzira Pimenta; Almeida Canova, Moara; Cataldi, Marcio; Costa, Giulia Angelina Silva da; Enrich Prast, Alex; Symeonakis, Elias; Brearley, FrancisThe Amazon rain forest covers an area of ~ 6.7 million km2 of South America; nearly 60% of it is in Brazil, while the rest is shared among eight other countries. This vast extent of rain forest is a globally significant ecosystem that provides numerous ecosystem services that benefit humanity including essential climate regulation, biodiversity conservation, and hydrological stability. However, deforestation and forest degradation have led to the loss of approximately 15% of the Amazon rainforest since the 1970s, primarily driven by agricultural expansion, illegal mining, logging, and wildfires. These pressures have triggered a cascade of consequences, including biodiversity loss, disruption of cultural and ecosystem services, depletion of carbon sinks, and severe alterations to the hydrological cycle. While initially manifesting at local and regional scales, these effects increasingly pose risks to global climate stability. We simulated deforestation scenarios (15%, 50%, and 100% forest loss) using the Community Atmosphere Model (CAM 3.1) to evaluate precipitation changes and atmospheric responses. Results indicate substantial reductions in regional precipitation, hydrological disruptions affecting agricultural productivity, and an increasing risk of the Amazon transitioning from a carbon sink to a carbon source. This underscores the urgency of policy interventions, including stricter environmental regulations, trade restrictions on commodities produced illegally or in deforested areas, enhanced Indigenous land protection, and international cooperation to mitigate deforestation and promote sustainable land use. Immediate action is necessary to prevent irreversible ecological and climatic tipping points.
