Abstract This article provides a comparative analysis of unmanned aircraft flight regulatory documents to assist and support the construction and development of technology and innovation startups around unmanned aircraft in smart cities. The identification of the main research factor is based on countries with academic scientific production using the database of the Web of Science (WOS) platform. In summary of the results and contributions, a regulatory view and the non-standardization of documents between the countries that present the future trends for the sector was evidenced.

Resumo As cidades e seu constante crescimento têm um papel crucial no desenvolvimento sustentável global. O objetivo deste artigo é apresentar uma estrutura conceitual de governança colaborativa para a formação de cidades sustentáveis. A adoção do método de estudo de casos múltiplos (5) permitiu compreender a realidade das cidades de Copenhague (Dinamarca), Amsterdã (Holanda), Londres (Inglaterra), Hamburgo (Alemanha) e Barcelona (Espanha). As fontes de evidências foram coletadas por meio de entrevistas em profundidade, documentos e observação, sendo que a análise de dados foi realizada utilizando o software NVivo. Para tanto, realizou-se pesquisa exploratório-descritiva com abordagem de pesquisa qualitativa. Os resultados apresentam estratégias, benefícios, riscos e limites inerentes aos sistemas de governança colaborativa nas cidades e trazem contribuições para o desenvolvimento da teoria da governança.

Abstract Cities and their constant growth have a crucial role in global sustainable development. The objective of this article is to present a conceptual framework of collaborative governance for the shaping of sustainable cities. The adoption of the multiple case study (5) method allowed understanding the reality of the cities of Copenhagen (Denmark), Amsterdam (Netherlands), London (England), Hamburg (Germany) and Barcelona (Spain). Sources of evidence were collected through in-depth interviews, documents, and observation, plus the data analysis was performed by using the NVivo software. For that, exploratory-descriptive research was conducted with the use of a qualitative research approach. The results exhibit strategies, benefits, risks, and limits inherent to collaborative governance systems in the cities and bring contributions to the development of the governance theory.
