Glad to share with you our team’s sixth paper published in 2024, online on 27 February 2024: Citation: Nguyen, K.A. and Y.-A. Liou*, 2024. Rethinking Our World: A Perspective on a Cleaner Globe Emerging from Reduced Anthropogenic Activities, Geoscience Letters. 11, 9 (2024). https://lnkd.in/gP6zhrDr. Stringent measures, such as lockdowns, were implemented to curb the virus's spread, leading to reduced pollution levels and environmental improvements at various geographic scales, from cities to regions and nations. This study aims to fill the gap by uncovering the modifications of global spatiotemporal eco-environmental vulnerability patterns between pre-pandemic (2016) and amid-pandemic (2020) periods. By analyzing various factors influencing the eco-environmental health or geo-health, such as human activities, climate change, and ecological dynamics, we seek to understand the intricate relationships and dynamics within these influential factors. We examined six categories of environmental vulnerability, which encompassed socioeconomics, land resources, natural hazards, hydrometeorology, and topography, using a five-dimension stressor framework. Our analysis revealed a significant decrease in vulnerability levels across all categories, except for the very low level increased by 78.5% globally. These findings emphasize the detrimental impact of human activities on the global environment. They underscore the urgency of implementing spatial management strategies that prioritize sustainable geo-health development and foster a more resilient Earth. 

Glad to share with you our team’s fourth paper in 2024: Citation: Y.-A. Liou*, Tran, D. P, & Nguyen, K.A., 2024. Spatio-temporal patterns and driving forces of surface urban heat island in Taiwan. Urban Climate. Volume 53, January 2024, 101806. https://lnkd.in/gfbnh8bi. The urban heat island (UHI) phenomenon, a significant anthropogenic alteration of the Earth system, has been extensively studied due to easy access to satellite data. However, comprehensive studies on the surface UHI (SUHI) in Taiwan are lacking. This study investigates the diurnal, seasonal, and spatial patterns of SUHI intensity (SUHII) and its driving factors in eleven Taiwanese cities from 2003 to 2020. Using stepwise multiple regression, Pearson's correlation, and land surface temperature (LST) data from Aqua/Terra MODIS, we explored SUHII relationships. Findings indicate daytime SUHII (2.21 to 6.78 °C) is more intense than nighttime (0.52 to 1.63 °C), with higher intensities in northern cities. Significant seasonal variation was noted, with daytime SUHII correlating with normalized difference latent heat index (NDLI), vegetation, built-up intensity, and heat emissions, while nighttime SUHII correlated with built-up intensity, nighttime light, and vegetation. Daytime factors explained more SUHII variation (79.5 to 89.0%) than nighttime (44.9 to 77.0%), particularly in spring and winter. This study provides essential insights for developing heat mitigation strategies.

Last Call! Arctic Congress is still accepting abstracts for sessions until 19 January 2024.  Call for Abstracts portal:  https://lnkd.in/gfuxjt7B Please consider submitting to the following session on youth and communities in the Arctic. SESSION 4.0.6: People of the North; Building Active and Inclusive Participation of Arctic Youth and Communities through Community and Citizen Science Conveners: Janet Warburton, Roben Itchoak, and Katie Spellman Session Description: This session will explore the role of youth and communities in Arctic-focused research with a particular focus on how to equitably include and support them through community and citizen science research projects in the Arctic. With the Arctic facing unprecedented changes due to climate change and other human activities, community, and citizen science offer an opportunity for Arctic communities to actively participate in and lead research, to better understand the scope of changes happening in their environment, and to develop solutions based on Indigenous Knowledge and local expertise. Youth involvement is a crucial aspect of community and citizen science as a means to care for and protect their community, protect their environment, and nurture their leadership skills. The session will feature presenters from a variety of perspectives who have implemented community and citizen science projects throughout the Arctic with a specific focus on including youth and communities. Presentations will cover the benefits of community and citizen science, challenges and opportunities, and best practices for equitable inclusion of youth and communities. Throughout the session, participants will learn about the power of community and citizen science in sharing knowledge, addressing locally relevant issues, fostering community leadership in research and data sovereignty, and contributing to scientific knowledge and policy.

An exciting scientific breakthrough explained in layman's language: How protecting peat swamps can lock up more carbon, and how this carbon can be accurately calculated to underpin the trading of carbon credit by protecting the peat swamps. This piece of news is particularly relevant to the region, as the research was done primarily in Brunei by the Singapore-MIT Alliance for Research & Technology led by Charles Harvey, Alex Cobb, with the support of government agencies and scientific colleagues in Brunei. The article also quotes Dr Shawn Lum of NTU explaining the significance of this scientific breakthrough. https://lnkd.in/gVZXh_nn Linus Koh Vivek Kumar, F.IODKamal Prakash Seth
