Among various pollutants, fine particulate matter (PM_2.5}¹⁾ refers to particles with a diameter of 2.5㎛ or less. Inhaling PM_2.5 can cause cardiovascular and respiratory diseases, increasing premature mortality and can aggravate skin inflammation and allergies. In this sense, I observed data-driven trends in PM_2.5 concentrations in South Korea from 2017 to the most recent year, 2025. The dataset was downloaded from Air Korea (https://www.airkorea.or.kr/), operated by the Ministry of Climate, Energy and Environment and the Korea Environment Corporation. The national PM_2.5 maps below were estimated using Ordinary Kriging, which is based on the spatial interpolation²⁾ using the data from 665 monitoring stations across the country.³⁾ The most notable observation is the continuous decline in PM_2.5 levels from 2017 to 2025. In 2017, concentrations ranged from a maximum of 30μg/m³ to a minimum of 19μg/m³. By 2025, these figures dropped to a maximum of 20μg/m³ and a minimum of 13μg/m³, showing an overall decrease of approximately 33%. Based on the reinforced annual average standard (15μg/m³) introduced in 2018, no region met the target in 2017; however, by 2025, many regions exhibited concentration levels comparable to or below the standard threshold. This downward annual trend in PM_2.5 can also be corroborated by the Environmental Data Service Portal of the Korea Environment Institute (KEI, 2026). Looking at regional trends, high PM_2.5 levels in 2017 were mainly concentrated in the Seoul Metropolitan Area (SMA) and its surrounding cities (Pyeongtaek, Cheonan, Wonju, and Dangjin), as well as Gunsan, Iksan, and Jeonju in Jeonbuk State. By 2025, however, elevated concentrations were particularly evident in the western part of the SMA. In addition, compared to 2017, Chungcheongbuk-do and northern Gyeongsangbuk-do displayed relatively higher pollution levels than other regions. In this regard, Professor Sang-Deok Lee's research team from the Department of Integrated Particulate Matter Management at Kangwon National University Graduate School explained: "The high PM_2.5 pollution in Chungcheongbuk-do may be attributed to mountain ranges inducing atmospheric stagnation." They added, "Pollutants carried by winds blowing from the SMA, including Seoul, accumulate in the atmosphere as the surrounding mountains impede pollutant dispersion" (Lee et al., 2024). Although PM_2.5 levels have been consistently declining so far, a study titled ‘Atmospheric Patterns Associated with Fine Dust Generation on the Korean Peninsula and Future Outlook’ suggests a different scenario. Analyzing the 50-year future average (2050–2099) under climate change projections, the study indicates that winter northwesterly winds over the Korean Peninsula will weaken, and atmospheric conditions will stabilize. This will lead to warmer winter accompanied by an increase in fine particulate concentrations (Lee et al., 2018; Choi, 2024). Finally, unlike the recent decline in fine dust, tropospheric ozone concentrations in our daily living environment are showing a long-term increasing trend. Tropospheric ozone is known to trigger respiratory illnesses, asthma, and Chronic Obstructive Pulmonary Disease (COPD) (Choi, 2024). Therefore, to move forward, it is essential that we pay close attention not only to particulate matter but also to ozone levels.   Footnotes 1) PM_2.5 is directly emitted as a primary pollutant from industrial facilities, vehicle exhaust, and heating, while also being secondarily formed in the atmosphere as compounds such as sulfates and nitrates through chemical reactions (Seoul Metropolitan Government Atmospheric Policy Division, 2026). 2) Spatial Interpolation is a method used to estimate values at unobserved locations using known values at specific spatial locations (points). Among these methods, Ordinary Kriging is widely utilized for estimating particulate matter concentrations by applying a weighted linear combination of surrounding known monitoring values. 3) Since Ordinary Kriging does not incorporate state-of-the-art AI techniques or high-resolution remote sensing or raster datasets, it is difficult to claim that these maps provide perfectly accurate micro-scale predictions. However, it is fully sufficient for capturing national-level spatial trends. - 참고문헌

Utilizing 'NatureScore™,' a metric developed by NatureQuant to evaluate the quality and quantity of natural surroundings—including green and blue spaces—for over 65,000 public schools across the United States, the study found a consistent trend: schools serving marginalized student populations scored lower across the board. In urban areas, the gap in NatureScore (on a scale of 0 to 100) between schools attended by wealthy students and those serving underprivileged students reached as high as 20 to 25 points. While the disparity was smaller in rural areas, it remained statistically significant. The joint research team explained that children in marginalized communities face structural barriers to accessing nature, which can negatively impact their stress levels, cognitive functions, and overall health and well-being. The study recommends intensive greening initiatives—such as tree planting, the creation of pocket parks, and nature-based learning—specifically for underserved school districts. "Access to nature is not just an environmental issue; it is a social challenge directly linked to educational equity," stated Prof. Kangjae Lee. "Tailored greening policies for vulnerable students can contribute to improving both health and academic performance." He added, "This research is significant as it presents a new approach to solving environmental and educational inequalities through international collaboration between academia and industry." Prof. Kangjae Lee served as the corresponding author, and Ashraf Khadija, a PhD student in the Department of Convergence & Fusion System Engineering, was the lead author. This study was conducted as part of the Korea-Türkiye Cooperation Foundation Project supported by the National Research Foundation of Korea (NRF). The findings were published on September 9, 2025 in Urban Forestry & Urban Greening, a top-tier international journal ranked in the upper 1.6% of the JCR Forestry category.]]> Wed, 04 Mar 2026 00:43:49 +0000 Link: https://www.newsis.com/view/NISX20241104_0002946007 The Korea Research Institute for Human Settlements (KRIHS) announced on the 4th that it will hold the "2024 International Conference on GIS (ICGIS)" on November 6, 2024 at KINTEX in Goyang, Gyeonggi Province.

Prof. Kangjae Lee, the lead and corresponding author of this study, designated South Korea as the research area and confirmed spatiotemporal non-stationarity in the relationship between green spaces and stress. As the COVID-19 pandemic has significantly highlighted the impact of green spaces on human mental health, such as stress, this study identified regional heterogeneity in the relationship between stress and green spaces from 2018 to 2021, accounting for both temporal shifts and spatial administrative boundaries (Si-Gun-Gu). Distinguishing itself from previous research, this study categorized green spaces into three types—forests, grasslands, and the Normalized Difference Vegetation Index (NDVI)—and examined how these different types of vegetation related to perceived stress in South Korea before and after the pandemic. The research team discovered that forest cover consistently maintained a negative correlation with perceived stress on a global scale. In contrast, grasslands and NDVI showed mixed associations with perceived stress at the global level. The research team emphasized that these findings underscore the necessity for local governments to develop diverse urban greening strategies for health promotion that respond to specific sociodemographic and existing environmental conditions.]]> Tue, 03 Mar 2026 23:59:07 +0000
