“…To quantify the relationship between regional ecological environment and economic development, Lu Yu used STIRPAT (stochastic impacts by regression on population, affluence, and technology) with indicators such as ecological stress index, ecological coordination coefficient, and ecological footprint diversity index. extended model combined with principal component regression model to analyze the main drivers of 3D ecological footprint evolution; Xiong Xi introduced the European Environment Agency's DPSIR (i.e., driver-pressure-state-impact-response) environmental management model into its ecological civilization construction analysis evaluation [21], using rough set theory and methods to carry out analysis and evaluation regarding its ecological civilization construction; Xin constructed a land use intensity indicator system and a coupled coordination degree model to explore the relationship between ecological service value and land use intensity and the reasons for their changes [22]. Therefore, in order to evaluate the ecosystem health of Fujian Province more comprehensively, it is necessary to explore the comprehensive impact of social and economic development on the ecological environment, and this paper will construct a land use intensity system in Fujian Province from the social and economic dimensions.…”

As the first pilot ecological civilization zone in China, Fujian Province has an excellent ecological environment quality, and its ecological environment-related indices continue to be among the highest in the country. In order to investigate the causes of the excellent ecological quality in Fujian Province in the past 15 years, this paper selects MODIS images, land use data and provincial and municipal statistical yearbook data of Fujian province from 2005 to 2020 as data sources, evaluates the ecological system health of Fujian Province by remote-sensing ecological index (i.e. RSEI), constructs the land use intensity system of Fujian Province at the same time, and uses a coupled coordination model to analyze the coupling between RSEI and The coupled coordination model was used to analyze the coupling relationship between RSEI and land use intensity, and finally the spatial and temporal evolution of ecological health in Fujian Province from 2005 to 2020 was analyzed. The results show that the coupled coordination between land use intensity and ecosystem health in Fujian province showed a continuous increase between 2005 and 2020, especially in Ningde, where the increase was most significant, from 0.0993 to 0.963, this pattern of spatial distribution is lower in the south-eastern coastal region than in the north-western interior, higher in the south-western region than in the north-western region, and higher in the north-eastern region than in the south-eastern region. In terms of the type of role, the land use intensity of most cities in Fujian Province in 2005 played an obvious role in blocking the degree of ecosystem health, but as time changed, urban land use continued to be optimized and reached moderate or even high quality coordination with the quality of the ecological environment, but Xiamen City developed relatively slowly and its 2020 coupling degree value was 0.315, which was still in mild disorder. This study fills a gap in the research mechanism of the interaction between the degree of ecosystem health and land use intensity, and also provides a new perspective for the construction of ecological civilization and the assessment of the degree of ecosystem health in Fujian Province and the whole country.

“…Additionally, GI can aid in adaptation to climate change in three main aspects: urban heat island effect—by regulating temperature in urban spaces, especially in population-dense locations [ 44 , 45 , 46 ]; flood risk management—through green cover that can reduce water runoff [ 44 , 47 ]; and ecosystem resilience—by preventing ecosystem fragmentation while increasing the number of protected areas and maintaining habitat connectivity [ 44 , 48 ].…”

Coastal areas are home to more than 2 billion people around the globe and, as such, are especially vulnerable to climate change consequences. Climate change adaptation has proven to be more effective on a local scale, contributing to a bottom-up approach to the problems related to the changing climate. Portugal has approximately 2000 km of coastline, with 75% of the population living along the coast. Therefore, this research had the main objective of understanding adaptation processes at a local scale, using Portuguese coastal municipalities as a case study. To achieve this goal, document analysis and a questionnaire to coastal municipalities were applied, and the existence of measures rooted in nature-based solutions, green infrastructures, and community-based adaptation was adopted as an indicator. The main conclusion from this research is that 87% of the municipalities that answered the questionnaire have climate change adaptation strategies implemented or in development. Moreover, it was possible to conclude that 90% of the municipalities are familiar with the concept of nature-based solutions and all the municipalities with adaptation strategies include green infrastructure. However, it was also possible to infer that community-based adaptation is a concept that most municipalities do not know about or undervalue.

“…According to the United Nations Environment Programme 18 , sustainable urban cooling initiatives are necessary, and nature-based blue-green spaces (BGS) are among the most powerful tools for decreasing cooling requirements and improving outdoor thermal comfort. For example, BGS can reduce the surrounding temperature through shading, evapotranspiration, and air convection, thereby creating a cold island (CI) effect 19,20 . The focus of urban BGS research has been on cooling mechanisms 21,22 , cooling effects 23,24 , economic bene ts 25 , accessibility, and equity 26,27 .…”

Urban blue–green spaces(BGS) exhibit a remarkable cold island (CI) effect, and research on heat mitigation measures based on CIs has attracted considerable attention. However, few studies have been conducted on mitigating urban overheating by connecting isolated CI patches to form CI networks. Therefore, this study aimed to explore the framework and specific processes for building an urban CI network in Hangzhou, China. The CI network construction framework consisted of “source identification-resistance surface construction-corridor construction”. Based on morphological spatial pattern analysis, local climate zone (LCZ) theory, connectivity index, and circuit theory, the CI sources and cooling corridors were identified and classified, and the pinch and barrier points in the network were determined. The results indicated that the CI network in Hangzhou comprised 69 CI sources, 134 cooling corridors, 36 pinch points, and 89 barrier points. Based on these results, we recommended that the LCZs in the CI network that are dominated by water (LCZG) and dense trees (LCZA) be protected and areas that are dominated by bare rock or pavement be improved. This study and methodology can provide new inspiration for future planning of urban BGS and sustainable urban cooling.
