  • Greening rate in North Korea doubles South Korea

    Open AccessSai Qu, Youngryel Ryu et al.ARTICLEEnvironmental Research Letters2023

    South and North Korea have experienced contrasting economic developments since the 1950s while sharing similar climates. Previous studies revealed an overall long-term greening trend across the Korean Peninsula based on greenness data from coarse-resolution satellite images. However, there has been no comprehensive comparison of the greenness patterns and the driving mechanisms between two countries due to the limitations of coarse-resolution sat…

  • Expanding vegetated areas by human activities and strengthening vegetation growth concurrently explain the greening of Seoul

    Open AccessYorum Hwang, Youngryel Ryu et al.ARTICLELandscape and Urban Planning2022

    Many studies have reported that urbanization leads to a decrease in the normalized difference vegetation index (NDVI) due to the expansion of impervious cover. Some studies, however, have reported positive NDVI trends in urban areas due to warming and CO2 fertilization effects, as well as the creation of green space. Thus, we examined spatial and temporal variations of the growing season maximum NDVI in a megacity, Seoul, which has rapidly urbani…

  • The magnitude and causes of edge effects on soil organic carbon stocks within and across urban to rural forest patches

    Open AccessJeehwan Bae, Youngryel RyuARTICLELandscape and Urban Planning2021

    Landscape fragmentation has created large areas of forest edge. Understanding how soil organic carbon (SOC) stocks within forest edges respond to fragmentation is essential to assess carbon budgets; however, the causes and magnitude of edge effects on SOC stocks have been poorly characterized. Here, we quantify the edge effects on SOC stocks within and across urban to rural forest patches from three fragmented urban forests to a large patch of ru…

  • High soil organic carbon stocks under impervious surfaces contributed by urban deep cultural layers

  • Increased atmospheric vapor pressure deficit reduces global vegetation growth

    Open AccessWenping Yuan, Yi Zheng et al.ARTICLEScience Advances2019

    Global vegetation greening trend stalled after the late 1990s due to increased atmospheric water demand.

  • Describing the spatial patterns of heat vulnerability from urban design perspectives

    Open AccessSaehoon Kim, Youngryel RyuARTICLEInternational Journal of…2015

    A large number of East Asian cities, like cities in other parts of the world, are being affected by extreme heatwaves. Yet, little is known about the general urban design characteristics of sites with significant heat vulnerability within the localized context. In this study, empirical data sets were constructed describing the biomedical, social, environmental, and place-based parameters associated with the location of heat-related emergency call…

  • Urban heat mitigation by roof surface materials during the East Asian summer monsoon

    Open AccessSeungjoon Lee, Youngryel Ryu et al.ARTICLEEnvironmental Research Letters2015

    Roof surface materials, such as green and white roofs, have attracted attention in their role in urban heat mitigation, and various studies have assessed the cooling performance of roof surface materials during hot and sunny summer seasons. However, summers in the East Asian monsoon climate region are characterized by significant fluctuations in weather events, such as dry periods, heatwaves, and rainy and cloudy days. This study investigated the…
