“…The city is an artificial system based on the natural environment. If this artificial system is in the process of establishment and development, inadequate treatment of nature and protection of nature can easily cause the original ecological environment in the urban area to gradually shrink and trigger a vicious ecological environment effect [ 2 , 3 ]. The second is that the living resources are seriously polluted.…”

Cities are gradually developed on the basis of adapting and transforming the natural environment. In a certain urban area, human activities, natural environment, and other factors and their mutual influence constitute the urban ecological environment. Therefore, the evaluation of urban ecological environment quality is of great significance to the analysis of urban development. This paper takes a city in Western China as the evaluation object, uses AHP to determine the index weight, reasonably analyzes the current situation of the urban ecological environment, and further comprehensively evaluates the quality of the urban ecological environment. The study shows that from 2013 to 2018, the comprehensive capacity of the city’s ecological environment quality showed a steady upward trend, except that the natural disasters of floods and mudslides in 2014 had a certain degree of fluctuation. The comprehensive index of ecological environment quality has increased from 0.337 in 2013 to 0.412 in 2018. The overall level is still low, but the development speed is relatively stable. The urban ecological environment has been gradually improved, and society, economy, and nature have maintained a certain degree of sustainable development.

“…Addressing urban environmental challenges requires an unwavering commitment to sustainable development-a comprehensive strategy that effectively balances current needs with the longterm well-being of both present and future generations. To pave the way for sustainable progress, cities must direct resources towards ongoing research and innovative solutions, spurring the identification of practical approaches to solving environmental problems (Esau et al, 2021;Wolf et al, 2020Wolf et al, , 2021.…”

This paper highlights the importance of improving stakeholder understanding of environmental factors such as air quality and the urban heat island effect to achieve sustainable development goals. While accurate spatial and temporal environmental data are critical for sustainable solutions, the challenge lies in translating complex environmental information for non‐specialists. To solve this problem, we propose using web GIS storytelling as a powerful tool for communicating and disseminating information about the environment. This paper aims to show example of implementation of a web‐based geographic information system (GIS) on our case study in Bergen, Norway. This platform “Web GIS Bergen, air quality and thermal comfort” was created as an open portal. This document explains the components of the platform, their rationale, and implementation, which includes important steps. They involve the collection of relevant environmental data, including modeling results and remote sensing data. Futhermore, the design and interface of the platform has been carefully considered to provide a user‐friendly experience based on interactive maps and storytelling. Combining data visualization and storytelling, the platform promotes a comprehensive understanding of complex environmental data, including “invisible killers” such as air pollution and the urban heat island effect, which significantly affect sustainable development. The strategic integration of this web‐based GIS platform in Bergen can serve as an attractive model for other urban areas looking for practical tools for sustainable development, engaging stakeholders for a healthier and more sustainable urban future.

“…Uncertainty in emissions and surface boundary conditions currently impede fine tuning of the simulations. Societal uncertainties could be also influential (Felius et al, 2019;Wyss et al, 2016). Heating patterns and habits are poorly constrained.…”

“…To obtain the actual emission rates, one must know consumption of wood per unit time per stove and frequency of using the stoves, i.e., parameters that characterize burning habits in the city. Felius et al (2019) published an updated study of the woodburning habits in Norway. It reveals that about 80 % of households use stoves only during the afternoon and evening hours, while 90 % of households still use wood burning as a sig-nificant (primary and secondary) heating source.…”

“…However, the need for heating during cold winter days implies that more realistic policy actions must be considered. Moreover, active use of the wood-burning stoves could be an effective retrofitting measure, helping to save electricity and fossil fuels (Felius et al, 2019). Therefore, a massive transition to new stoves is deemed necessary both from political and environmental points of view.…”

Abstract. Many cities in the world experience significant air pollution from residential wood combustion. Such an advection–diffusion problem as applied to geographically distributed small-scale pollution sources presently does not have a satisfactory theoretical or modeling solution. For example, statistical models do not allow for pollution accumulation in local stagnation zones – a type of phenomena that is commonly observed over complex terrain. This study applies a Parallelized Atmospheric Large-eddy simulation Model (PALM) to investigate dynamical phenomena that control variability and pathways of the atmospheric pollution emitted by wood-burning household stoves. The model PALM runs at spatial resolution of 10 m in an urban-sized modeling domain of 29 km by 35 km with a real spatial distribution of the pollution source and with realistic surface boundary conditions that characterize a medium-sized urban area fragmented by water bodies and hills. Such complex geography is expected to favor local air quality hazards, which makes this study of general interest. The case study here is based on winter conditions in Bergen, Norway. We investigate the turbulent diffusion of a passive scalar associated with small-sized particles (PM2.5) emitted by household stoves. The study considers air pollution effects that could be observed under different policy scenarios of stove replacement; modern woodstoves emit significantly less PM2.5 than the older ones, but replacement of stoves is a costly and challenging process. We found significant accumulation of near-surface pollution in the local stagnation zones. The simulated concentrations were larger than the concentrations obtained only due to the local PM2.5 emission, thus indicating dominant transboundary contribution of pollutants for other districts. We demonstrate how the source of critical pollution can be attributed through model disaggregation of emission from specific districts. The study reveals a decisive role of local air circulations over complex terrain that makes high-resolution modeling indispensable for adequate management of the urban air quality. This modeling study has important policy-related implications. Uneven spatial distribution of the pollutants suggests prioritizing certain limited urban districts in policy scenarios. We show that focused efforts towards stove replacement in specific areas may have a dominant positive effect on the air quality in the whole municipality. The case study identifies urban districts where limited incentives would result in the strongest reduction of the population's exposure to PM2.5.
