- The 15-minute city in Porto, Portugal: accessibility for the elderlyPublication . Guerreiro, Maria; Dinis, Maria Alzira Pimenta; Sucena, Sara; Pereira, Madalena Sofia Araujo; Silva, Isabel; Ferreira, Diogo; Silva Moreira, RuiThe concept of the 15-Minute City aims to enhance urban accessibility by ensuring that essential services are within a short walking distance. This study evaluates the accessibility of Porto, Portugal, particularly for the elderly, by assessing urban density, permeability, and walkability, with a specific focus on crossings and ramps. A five-step methodology was employed, including spatial analysis using QGIS and Place Syntax Tool, proximity assessments, and an in-situ survey of crossings and ramps in the CHP. The results indicate that while the city of Porto offers a dense and walkable urban environment, significant accessibility challenges remain due to inadequate ramp distribution. The data collection identified 80 crossings, of which only 60 were listed in OpenStreetMap, highlighting data inconsistencies. Additionally, 18 crossings lacked curb ramps, posing mobility barriers for elderly residents. These findings highlight the need of infrastructure improvements to support inclusive urban mobility. The study also proposes an automated method to enhance ramp data collection for broader applications. Addressing these gaps is crucial for achieving the equity and sustainability goals of the 15-Minute City model, ensuring that aging populations can navigate urban spaces safely and efficiently.

- How can higher education become climate-proof?Publication . Leal Filho, Walter; Raman, Raghu; Lange Salvia, Amanda; Londero, Luciana Brandli; Veiga Ávila, Lucas; Dinis, Maria Alzira Pimenta; Khaled, Nisrin Naiel DibHigher education institutions (HEIs) are increasingly exposed to climate-related risks, including extreme weather events, infrastructure disruptions, and related social and economic impacts. At the same time, they are expected to play a leading role in advancing sustainability and decarbonisation efforts. In this context, this paper aims to assess how HEIs are preparing to become climate-proof and to identify the institutional strategies, barriers, and priorities that shape the transition towards climate-resilient and sustainable higher education. Adopting a mixed-methods approach, the research combines comparative case studies of universities implementing climate adaptation and mitigation measures with a global online survey of 404 respondents from 83 countries, making it one of the largest studies on the topic undertaken to date. The case studies show three main typologies of institutional response, i.e., comprehensive integration, operational emphasis, and social–educational engagement, illustrating varying levels of maturity and coordination. The survey findings reveal that although more than half of assessed institutions have initiated inventories or decarbonisation strategies, implementation remains fragmented. Operational measures concentrate on energy systems and waste management, while systemic integration across curricula, governance, and community engagement is less common. Key barriers include limited financial capacity, fragmented institutional priorities, and insufficient stakeholder participation. The study shows that climate-proofing higher education requires transformative and cross-sectoral governance, aligning decarbonisation, education, governance and equity objectives.
- Trajectories of circular economy in cities: key patterns and emerging pathwaysPublication . Aina, Yusuf; Almulhim, Abdulaziz I.; Salami, Babatunde Abiodun; Swart, Julia; Abubakar, Ismaila Rimi; Dinis, Maria Alzira Pimenta; Sharifi, AyyoobUrbanisation and escalating resource pressures have intensified the need for systemic approaches to sustainable development, positioning the circular economy (CE) as a critical framework for cities. This study reviews academic literature to examine current trends, challenges, and forward-looking strategies for CE implementation in urban contexts. Using a search process aligned with the PRISMA protocol, 668 peer-reviewed articles were analysed through inductive content analysis. The findings reveal that CE practices in cities are increasingly shaped by global sustainability agendas, particularly in relation to SDGs 9 to 12. The analysis identifies eight thematic clusters that characterise urban CE pathways: urban planning and the built environment, energy and mobility systems, waste and resource management, water and urban agriculture, citizen engagement, governance and regulation, technological innovation, and socio-cultural transformation. A conceptual framework integrating eight thematic clusters is presented, illustrating how cities transition from linear to circular systems through policy alignment, digital innovation, and multisectoral collaboration. Case studies from global urban centres illustrate strategies ranging from smart infrastructure and circular procurement to social inclusion and localised production, all of which enable CE advancement. These findings reinforce the view of CE as a multidimensional approach capable of fostering urban resilience, environmental stewardship, and inclusive economic growth.
- Updating the charter of the United Nations in the age of Artificial Intelligence: a civilizational proposal under the aegis of Article 109Publication . Borges Gouveia, Luis; Future Group - APDSIThe APDSI Futures Group proposal (July 2026) advocates for a fundamental revision of the 1945 United Nations Charter to address the "constitutional disruption" caused by Artificial Intelligence. It argues that the original Charter, designed for a world of physical borders and sovereign nation-states, is inadequate for a 2026 reality dominated by autonomous cross-border systems operating in a legal vacuum. A central concept of the proposal is Cognitive Sovereignty, which defines the human mind as "critical infrastructure" and an international public good that must be protected from algorithmic manipulation and political microsegmentation. The document identifies a critical triad—Information, AI, and Energy—noting that AI governance is inseparable from environmental limits, such as the water and carbon footprints of data centers. It specifically warns against "algorithmic coloniality," where a technological oligopoly imposes Anglo-Saxon worldviews and exploits the Global South's resources and cognitive labor. The APDSI framework proposes eight founding principles to be integrated into a new Charter, including: - Primacy of Human Responsibility: Ensuring humans remain ultimately liable for autonomous decisions. - Democracy over Efficiency: Preventing technical efficiency from bypassing democratic scrutiny. - Irreversibility: Prohibiting technological adoptions that create essential dependencies without a "reverse gear". - Economic Justice: Taxing AI systems that replace human labor to fund social protection. The proposal establishes non-derogable prohibitions against self-replicating AI, autonomous lethal weapons without human oversight, and mass biometric surveillance. To implement these reforms, the group advocates for activating Article 109 of the UN Charter to convene a General Review Conference. Portugal is positioned as a vital mediator in this process, leveraging its "smart power" and ties to the Global South to bridge the gap between technological superpowers and developing nations.
