- 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.
