This webinar serves as a compelling entry point into the urgent global discourse on climate change and its profound implications for agriculture. It offers a platform to explore the intricate relationship between farming practices and the environment. The presentation sets the stage by underscoring the pivotal role of agriculture, which is both a contributor to and a mitigator of climate-related challenges. By delving into innovative strategies, sustainable approaches, and the latest research findings, this webinar empowers its audience to actively engage with the complexities of climate change adaptation. The eddy-covariance method were applied to understand the characteristics of sensible heat, water vapor, and CO2 fluxes above a subtropical monsoon rice paddy in north Taiwan. The mean air temperature and annual precipitation is 24 oC and 2540 mm. The crop season is from February to June, and the fallow season is from July to December. During crop season, about 25% of net radiation was used for latent heat flux, 10% for sensible heat flux, and the rest (65%) was absorbed by the water and soil in the rice paddy. During crop season the maximum CO2 uptake was about 22 mmol m-2 s-1. In fallow period, the maximum CO2 emission rate from the soil-water surface was about 5 mmol m-2 s-1. Penman-Monteith equation was found to reproduce the evapotranspiration well with surface resistance close to 190 s m-1. Under small Bowen ratio conditions, water vapor and CO2 were transported more efficiently than heat, which is different from typical dry land. Greenhouse gas emissions and global warming have emerged as critical climate issues in the 21st century. The relentless increase in these emissions has contributed to a rapid rise in global temperatures, resulting in widespread environmental and societal consequences. In response to this pressing challenge, the target of achieving net-zero emissions by 2050 has gained immense importance in the fight against climate change....

  Dr. Yo-Jin Shiau

  Assistant Professor·National Taiwan University

  Yo-Jin Shiau completed his B.S. and M.S. degrees in the Department of Bioenvironmental Systems Engineering at National Taiwan University before earning his Ph.D. degree from the Department of Biological and Agricultural Engineering at North Carolina State University. Following his graduation, he worked as a post-doctoral researcher at Academia Sinica, focusing primarily on carbon (C) and nitrogen (N) dynamics in various ecosystems. Currently, he holds the position of assistant professor in the Department of Bioenvironmental Systems Engineering at National Taiwan University. Dr. Yo-Jin Shiau specializes in the biogeochemical processes of carbon and nitrogen in anaerobic ecosystems, such as constructed wetlands, rice fields, and mangrove forests. He explores their responses to climate change and global warming across molecular to field scales.
