Accurate and reliable l land use/land cover (LULC) data are typically utilized as a crucial basis for research on resource management and ecological and environmental evaluation. Land resource surveys and remote sensing are main methods for understanding and grasping LULC changes. However, current LULC products lack updates and do not have sufficient access to finer-scale land survey statistics...
Recently, Professor Bai Yuqi’s team of the Department of Earth System Science (DESS), Tsinghua University and Researcher Li Fang’s team from the Institute of Atmospheric Physics (IAP), Chinese Academy of Sciences have jointly completed the research on the regional health effect of landscape fire emissions in China during 2021-2100. Based on the projected future population and landscape fire s...
On November 19, the 2023 China Report of the Lancet Countdown on Health and Climate Change (China Report) was launched in Beijing. This report was authored by 76 experts from 26 major institutions both domestically and internationally, led by the Lancet Countdown Regional Centre for Asia based in the Department of Earth System Science at Tsinghua University. The Vice President of Tsinghua Unive...
Land surface process is a key process in Earth’s surface system, and accurate estimation of land surface state plays an important role in improving the performance of an Earth system model. The Land surface data assimilation system improves the observability and predictability of land surface state variables by integrating the advantages of multi-source Earth observation data and land surface ...
China has been plagued by floods in history, where the flood losses account for about 10% of the world. In recent years, under the impact of climate change, extreme weather events such as heavy rainstorms and severe precipitation have occurred frequently, increasing the frequency and intensity of fluvial floods. Meanwhile, as China and other other developing countries undergo rapid urbanization...
Lin Guanghui’s Research Group of DESS, Tsinghua University discloses the seasonal variation pattern and driving mechanism of carbon and water fluxes of subtropical mangroves Mangroves, as one type of coastal “blue carbon” ecosystems, are highly efficient as carbon sinks, playing an important role in sequestering carbon dioxide and mitigating global climate change. Due to the lack of long-ter...
Mangroves, as an important part of coastal wetlands, play an important role in wind and wave resistance, protecting embankments and maintaining biodiversity, as well as sequestering atmospheric carbon dioxide (CO2) and mitigating global climate change. However, over the past few decades, with the construction of large-scale seawater aquaculture ponds for the development of aquaculture, the cove...
The iron and steel industry, with carbon dioxide emissions contributing about 25% of the total industrial emissions in the world, is the industry with the highest carbon emissions in the global industrial sector. Urbanization and industrialization in the recent decades have led to a sharp increase in steel demand, which has in turn promoted the construction of a large number of steel production...
