🟣 هفته کتاب و کتابخوانی در راهه و ما دوست داریم مخاطبان خودمون رو بیشتر بشناسیم.

🔸دلمون میخواد بدونیم چقدر کتاب می خونید و بیشتر تو چه زمینه هایی دوست دارید مطالعه کنید.

🔸قطعا منظورمون از کتاب اینجا، کتاب های درسی و کمک درسی نیست.

🔸کتاب های درسی سرجاش؛ دلمون میخواد بدونیم کلا میونه تون با کتاب تو وقتای خالیتون چطوره؟

🟣خوشحال میشیم این پایین تو نظرسنجی ما شرکت کنید.😊

Introduction
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.
Agricultural activities play a pivotal role in this climate equation, being recognized as significant sources of greenhouse gases, particularly methane (CH4) and nitrous oxide (N2O). These emissions result from various farming practices, including enteric fermentation in livestock and the application of synthetic fertilizers. However, it's important to note that agriculture is not solely a contributor to the problem but also holds the potential to be part of the solution. Through the implementation of sustainable and regenerative farming techniques, the high primary production in agriculture can transform the system into a net carbon sink. Proper land management practice, rational fertilization, alternative wetting and drying and soil carbon sequestration initiatives within the agricultural sector can all contribute to offsetting emissions, offering a pathway towards achieving the coveted net-zero emissions target.
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.
