Economic growth has dominated development strategies and goals for many years, but prosperity encompasses more than that. In 2013, UN-Habitat proposed the City Prosperity Initiative (CPI) as a tool to quantify cities' prosperity and sustainable development. The CPI is accompanied by six essential components with 62 indicators associated with the urban settlement, incorporating productivity, infrastructure development, quality of life, social inclusion, environmental sustainability, and urban governance and legislation. The research aims to use the indicators of CPI and adopted the Full Permutation Polygon Synthetic Indicator method to measure and evaluate the level of prosperity of Da Nang City of Vietnam with data from 2004 to 2019. According to the findings of our study, the value of a synthetic indicator for the prosperity of Da Nang City increased, from 0.34 in 2004 to 0.36 in 2009, 0.43 in 2014, and 0.45 in 2019, which indicates a moderate level of wealth. On the one hand, Da Nang City has high levels of quality of life, equity and social inclusion, and urban governance and legislation. However, the city still has modest determinants of prosperity in terms of the environment, productivity and infrastructure. The Full Permutation Polygon Synthetic Indicator technique provides a comprehensive solution that illustrates the system integration idea. As a result, the proposed methodology offers a potential foundation for decision-making to promote sustainable urban development strategies and assess the effectiveness of these actions

The increasing unpredictable floods due to the effect of climate change across regions of Vietnam have threaten the country’s socio-economic development goals at local, regional and national scales. This paper employs indicator-based approach to calculate Flood Vulnerability Index and generates vulnerability maps that reflect the spatial distribution of flood vulnerability in the Central region of Vietnam, which is the hardest hit flood region and home to many sites of great cultural-historical value. Data were collected from Hoi An’s 2020 statistical yearbook, digital elevation model, land use map, open street map and from surveying experts and civil servants at the city level (representatives of the City People’s Committee, the Center for Cultural Heritage Management and Preservation of Hoi An) and at ward/commune level (representatives of 12 wards and communes). GIS techniques and analytical hierarchy process were applied to analysis the obtained data and generate three scenarios that reflect the impact of vulnerability’s components. The findings indicate that number of organizations in disaster prevention and historical site preservation, road density, the presence of historical sites, flood frequency and average elevation are the key factors affecting the city’s vulnerability to flood hazard in the area of cultural heritage. The empirical results in Hoi An also indicate the importance of the number of poor households as an necessary factor when considering the sensitivity to flood in developing countries. In addition, this study distinguishes the impact of vulnerability’s components by generating different scenarios which clearly proof that having more floods does not always mean high vulnerability and vice versa. More importantly, by looking into the reasons (either transportation, education or other indicators) that leads to the gap between Flood Vulnerability Index in different scenarios, the paper subsequently identifies measures for each locality, whereby the governmental investment budget can be prioritized effectively.

... Há estudos que apontam que o desenvolvimento sustentável ainda não está incorporado nas estratégias, atividades e políticas de todo o sistema universitário(LIMA et al., 2023). Além disso, do ponto de vista metodológico, as abordagens mais recorrentes baseiam-se em estudos de casos individuais, investigações exploratórias destinadas a compreender as motivações dos principais tomadores de decisões nas IES para se envolverem com o tema(DI NAUTA et al., 2020).No caso de cidades, elas são motores do desenvolvimento económico, centros de cultura, ciência e educação além desempenhar um papel significativo na luta contra as alterações climáticas(TRUONG et al., 2023). Porém, mesmo os fatores de risco sob a forma de ESG recebendo cada vez mais atenção devido às suas preocupações ambientais e sociais, há pouca implicação desses indicadores no setor público, embora tenha sido encontrada uma vasta literatura sobre as empresas(ALJOWDER et al., 2023).2.1 Indicadores e Desafios em Quantificar as Ações ESG em Universidades, Empresas e Cidades Indicadores são, por definição, medidas quantitativas, qualitativas ou descritivas que permitem obter informações sobre um fenômeno complexo (ISO, 2018), em uma forma que seja fácil de usar e entender. ...

... The indicator-based methodology serves as a pivotal tool in the assessment of flood vulnerability, designed to clarify the various indicators contributing to the susceptibility of individuals, infrastructure, and systems to flood-related impacts (Leal et al., 2021;Nguyen et al., 2022). Through the combination and quantification of the indicators, it is possible to calculate a flood vulnerability index that represents the spatial variation of vulnerability across different locales. ...
