Climate change is the biggest global threat of our time. As a signatory nation of the Paris Agreement, Brazil has made a climate action commitment, and expressed its nationally determined contribution to reduce its greenhouse gas emissions by 37%. The Brazilian population is highly urban, and Brazilian cities are mostly responsible for greenhouse gas emissions, and the worst effects of global warming are experienced in cities. Hence, the fulfillment of the Brazilian climate commitments depends on the active engagement of municipalities. Nevertheless, the Brazilian national government does not monitor local climate actions, and it is not clear how local urban policy is aligned with climate action. In order to bridge this gap, this study tackles the question of: “Are, and if yes how, cities considering the climate emergency in their local planning mechanisms?” This question is investigated by placing five major Brazilian cities under the microscope. The methodological approach includes literature review and applied qualitative analysis to scrutinize how climate issues and actions are factored in urban planning regulations to verify if and to what extent local policies contribute to the fulfillment of the Brazilian nationally determined contribution, and sustainable development goals. The results disclose that investigated cities have adequately incorporated climatic issues in their urban planning mechanisms. However, policy concentrates more on adaptation rather than mitigation, and policy implementation yet to be realized.

While smart city transformation is a remarkably popular topic among urban policymakers across the globe, there is little evidence on how to evaluate a city’s smartness level accurately. This study aims to bridge this knowledge gap by applying a novel assessment framework to a case study context and generating useful insights. To achieve this aim, the study evaluates the smartness levels of 27 Brazilian state capital cities through the indicators of productivity and innovation, livability and well-being, sustainability and accessibility, governance and planning, and connectivity and innovation. This urban smartness analysis is conducted through a smart city assessment framework that brings up three categories of smart city performance types—i.e., leading, following, and developing. The findings of the analysis revealed that the common characteristics of cities with leading smartness performance are having: (a) a strong innovation ecosystem; (b) Specific legislation for developing entrepreneurship; (c) Training opportunities for skilled labor; and (d) Conditions for knowledge-based development and digital transformation offerings and readiness. The analysis identified the smartest cities in Brazil as follows: Florianópolis, São Paulo, Vitória, Curitiba, Porto Alegre, Brasília, Belo Horizonte, Rio de Janeiro, and Cuiabá. This study offers insights from the application of a novel method in the Brazilian context for the local authorities to consider adopting for smart city performance and progress analyses and subsequently making necessary interventions to transform their smart city policy and practice to realize their desired goals.

Unarguably, smart, sustainable, and knowledge-based development is critical for securing a livable future for our rapidly urbanizing world. The aim of this study is to generate insights into determining effective and efficient strategies to increase sustainability and innovation capabilities of cities to achieve long-term desired urban outcomes. This paper places the city of Florianópolis (Brazil) under the smart, sustainable, and knowledge-based urban development microscope. The methodological approach of the study involves a qualitative analysis through surveys (100 submitted forms, 55 responses received) and interviews (12) with key experts and stakeholders from Florianópolis. The findings of the study reveal that Florianópolis’ innovation ecosystem has high potential to thrive, but the city still has structural issues to deal with first, related to the gap between the potential to grow, and acknowledgement from key actors of the city to support the overall territory development considering the complex dimensions. This issue suggests amplifying the ecosystem’s vision, including different sectors and, especially, addressing innovation for the common good. The insights generated from the investigation of Florianópolis’ case are also invaluable to other cities’ planning for strategizing their transformation, and seeking smart, sustainable, and knowledge-based development pathways.

Resumo Elaborado com base na análise de dados oficiais, documentos internacionais, textos legislativos e extensa revisão bibliográfica, este artigo apresenta algumas reflexões sobre temas relevantes à implementação, pelas cidades brasileiras, dos Objetivos do Desenvolvimento Sustentável, fixados pela Agenda 2030 para o Desenvolvimento Sustentável da Organização das Nações Unidas, apontando os instrumentos legais existentes no âmbito da Política Nacional do Meio Ambiente, Política de Gestão de Recursos Hídricos, Estatuto da Cidade e Política Nacional de Proteção e Defesa Civil, com ênfase às ações e estratégias urbanas de mitigação, adaptação e resiliência às mudanças climáticas, no intuito de contribuir, na universidade, para a orientação de pesquisas científicas inter e transdisciplinares, articuladas com a formulação, implementação e avaliação de políticas públicas e voltadas a prover soluções para o enfrentamento dos complexos desafios de gestão e planejamento enfrentados pelas cidades contemporâneas.

This paper outlines a significant research gap on sustainable cities: the need for more comprehensive and strategic frameworks for managing sustainable cities, particularly those integrating interdisciplinary elements, dimensions, and global trends. The proposed framework delineates sustainable cities’ elements, dimensions, and trends based on ISO 37120, incorporating pillars linked to the triple bottom line and the Sustainable Development Goals 30 (SDGs). This study suggests specific research agendas, emphasizing theoretical and practical implementation within urban contexts. The methodological approach involved both bibliometric and content analysis techniques, using IRA-MUTEQ software 0.8 Alpha 7. This enabled the identification of key analytical categories and leading authors, with categories derived from lexical forms, similarity analysis, correspondence factor analysis (CFA), and descending hierarchical classification (DHC). Notably, the terms ‘ISO’ and ‘37120’ did not emerge as prominent lexical forms in the IRAMUTEQ results, despite their frequent mentions in the analyzed studies.

This paper explores if and how the idea of progressive property can help to shape more inclusive, sustainable, and just cities around the globe. While quite nuanced, at its heart the progressive perspective on property considers property as a means of addressing important human needs. It is consistent with reciprocal and communitarian approaches to property rights. Nowhere are these insights more relevant or needed than in cities—dense urban areas where legacies of exclusion have deprived disadvantaged groups of housing and public services. In cities and neighboring suburbs, the right to exclude collides head-on with the need to share limited space with those of little means. By re-examining the work of progressive property scholars, we suggest concrete ways of reconceptualizing access to the city. This paper ties legal theory to housing and city-planning by proposing an international perspective to progressive property scholarship, with a focus on local government policies pertaining to housing. We do so by comparatively examining case studies from the United States (US), Spain, Brazil, and Israel—four countries that are actively experimenting with progressive definitions of property in a manner which affects urban planning and housing in cities.
