Research highlights drought risk and awareness gaps in global society
Natural disasters have threatened human beings and the ecosystem. Among the various natural disasters, drought is one of the most insidious and costliest, adversely affecting the global economy and livelihoods. Unlike sudden disasters such as earthquakes or hurricanes, drought is a slow-onset phenomenon that gradually intensifies. This prolonged nature of drought often results in the […]
Scientists predict high groundwater depletion risk in South Korea by 2080
Groundwater forms when precipitation such as rain and snow seeps into the soil, replenishing rivers and lakes. This resource supplies drinking water. However, a recent study has alarmed the scientific community by predicting that approximately three million people in currently untapped areas of Korea could face groundwater depletion by 2080. A research team, led by […]
Catalyst developed to purify municipal sewage while enhancing hydrogen generation efficiency
Researchers have devised a novel catalyst aimed at enhancing the efficiency of reactions using contaminated municipal sewage to produce hydrogen—a green energy source. Their research was recently featuredin Advanced Functional Materials. With the growing environmental concerns of pollution associated with fossil fuel, hydrogen has garnered increased interest. Water electrolysis technology is a sustainable process that […]
Monitoring the well-being of reservoir water through an uncrewed surface vehicle
In a recent tragic incident, approximately 100 elephants in Africa perished due to inadequate access to water. The United Nations Environment Programme (UNEP) warned that around 2.5 billion people worldwide could face water scarcity by 2025. In the face of water shortages affecting human society and the entire ecological community due to the climate crisis, […]
Global warming intensifies typhoon-induced extreme precipitation over East Asia
Last year, Typhoon Hinnamnor — which caused 36 fatalities — gained notoriety as the first super typhoon that developed at a high latitude as 25°N since Korea Meteorological Administration records began. This year in Osong, Chungcheongbuk-do, an unanticipated intense downpour, caused rivers to suddenly overflow, resulting in numerous casualties. Earth's rising temperatures are triggering unprecedented […]
Dams in the Seomjin River basin, Korea, run smarter with AI
In August 2020, following a period of prolonged drought and intense rainfall, a dam situated near the Seomjin River in Korea experienced overflow during a water release, resulting in damages exceeding 100 billion won (USD 76 million). The flooding was attributed to maintaining the dam’s water level 6 meters higher than the norm. Could this […]
New approach to water electrolysis for green hydrogen
Professor Yong-Tae Kim’s team at POSTECH pioneers a novel approach to water electrolysis catalysts for green hydrogen production.
Unveiling global warming’s impact on daily precipitation with deep learning
A research team has conclusively demonstrated that global warming stands as primary driver behind the recent increase in heavy rainfall and heatwaves using deep learning convolutional neural network.
Water harvesting in Death Valley: Conquering the arid wilderness
A joint team of researchers from POSTECH and UC Berkeley successfully harvest water from the atmosphere using ambient sunlight.
