Resumo
O objetivo geral deste estudo é caracterizar como as intervenções possibilitaram
melhorar o habitat humano e a adaptação a mudanças climáticas utilizados no projeto
do canal Cheong Gye, Seul. A discussão posta surge com o interesse em
compreender como a sociedade pode conviver com corpos hídricos em meio urbano
de modo sustentável e tem como objetivo estudar a intervenção no Canal Cheong
Gye, em Seul, Coréia do Sul, analisando seus aspectos urbano, funcional e ambiental,
considerando o seu contexto cultural, legal e econômico. A intervenção envolveu 5,8
quilômetros, contemplando seu entorno próximo e foi executada entre 2003 e 2005,
sendo positivamente avaliada pelos usuários e tendo o local se tornado mundialmente
conhecido, proporcionando grande visibilidade a Seul. Através desta pesquisa
procura-se entender como isso pode ser emulado em outros diversos locais. A
discussão se apoiará em correntes teóricas da sustentabilidade urbana com base
transdisciplinar, entendendo a cidade como um organismo complexo, onde afloram
conflitos de interesses. A análise se apoia em materiais de origem secundária,
provenientes do projeto em si, dos estudos já elaborados sobre o mesmo caso e
contou com três 3 etapas: coleta, análise e interpretações do material. Os resultados
apontaram que: compreender o aspecto da funcionalidade do projeto, quanto a
drenagem urbana, quanto às novas dinâmicas de mobilidade, e quanto a seu desenho
e sua consequente influência urbana e ambiental. Busca-se entender os conflitos de
interesse envolvidos à época e as formas de sua resolução durante a implementação,
bem como o processo de operação e manutenção considerado complexo, hoje com
20 anos de existência. Conclui-se que, diante da pesquisa efetuada, entende-se que
a intervenção na sub bacia do Canal Cheong Gye se dá com o conceito de
regeneração ligado a questão ambiental e a de requalificação do espaço urbano. Ao
olhar demais países, pode-se inferir que a recuperação de cursos d´água em especial
nas áreas centrais, é uma preocupação que se tornou política pública na Asia Oriental
e na Europa, e em áreas menos centrais na América do Norte. Porém em países do
sul global, não observamos essas ações.
The general objective of this study is to characterize how interventions have made it possible to improve the human habitat and adaptation to climate change used in the Cheong Gye canal project, Seoul. The discussion arises from an interest in understanding how society can live with bodies of water in an urban environment in a sustainable way and aims to study the intervention in the Cheong Gye Canal in Seoul, South Korea, analyzing its urban, functional and environmental aspects, considering its cultural, legal and economic context. The intervention covered 5.8 kilometers, including its immediate surroundings, and was carried out between 2003 and 2005. It was positively evaluated by users and the site became known worldwide, giving Seoul great visibility. This research seeks to understand how this can be emulated in other locations. The discussion will be based on theoretical currents of urban sustainability with a transdisciplinary basis, understanding the city as a complex organism, where conflicts of interest arise. The analysis is based on secondary material from the project itself and from studies already carried out on the same case, and involved three stages: collecting, analyzing and interpreting the material. The results indicated that: understanding the functionality aspect of the project, in terms of urban drainage, new mobility dynamics, and its design and consequent urban and environmental influence. It seeks to understand the conflicts of interest involved at the time and the ways in which they were resolved during implementation, as well as the process of operation and maintenance of the complex, now 20 years old. In conclusion, the research carried out shows that the intervention in the Cheong Gye Canal sub-basin is based on the concept of regeneration linked to environmental issues and the requalification of urban space. Looking at other countries, it can be inferred that the restoration of watercourses, especially in central areas, is a concern that has become public policy in East Asia and Europe, and in less central areas in North America. However, in countries of the global south, we do not observe such actions.
