Abstract

The simultaneous measurements of broadband normalized difference vegetation index and net ecosystem production were carried out at Rzecin wetland in 2009. Additionally, carbon fluxes, ecosystem respiration and gross ecosystem production were estimated on the basis of measured net ecosystem production values. The maximum broadband normalized difference vegetation index value (0.73) was measured on the 6th of July. The minimum broadband normalized difference vegetation index value measured before and after the vegetation period was 0.40. The annual dynamics of carbon fluxes and broadband normalized difference vegetation index runs were different from each other. During the second half of vegetation period greenness of plants decreases more slowly than plants carbon dioxide uptake capacity. These differences are likely to be determined by plants aging. The results presented in this paper show potential applicability of broadband normalized difference vegetation index for the estimation of carbon dioxide exchange in wetlands.

COVID-19 pandemic underscores role of green space in urban carbon dynamics

K. Hwang, S. A. Papuga

Summary: COVID-19 in Detroit led to measures to prevent virus spread, resulting in changes in traffic and energy use. The study explores CO2 dynamics in this postindustrial city with a declining population and increasing green space. Results show that Detroit was a carbon source throughout the study period, with reduced traffic leading to lower CO2 concentrations and NUE. However, during the post-order period with higher traffic, atmospheric CO2 concentrations and NUE were lowest, indicating the potential of urban greening for carbon mitigation.

Climate controls over phenology and amplitude of net ecosystem productivity in a wheat-maize rotation system in the North China plain

Zewei Yue, Zhao Li, Guirui Yu, Zhi Chen, Peili Shi, Yunfeng Qiao, Kun Du, Chao Tian, FengHua Zhao, Peifang Leng, Zhaoxin Li, Hefa Cheng, Gang Chen, Fadong Li

Summary: Investigating the response of net ecosystem productivity (NEP) to phenological variation for crop ecosystems is important for understanding the impact of climate change on agriculture. However, the controlling mechanisms for rotation cropland ecosystems have not been well understood. This study used a 16-year flux observation to explore the potential of carbon flux phenology (CFP) and abiotic factors in interpreting the interannual variability (IAV) of NEP. The results showed that NEP was significantly controlled by different factors in wheat and maize seasons, and the carbon budgets varied depending on the season.

Partial cutting of a boreal nutrient-rich peatland forest causes radically less short-term on-site CO2 emissions than clear-cutting

Mika Korkiakoski, Paavo Ojanen, Juha-Pekka Tuovinen, Kari Minkkinen, Olli Nevalainen, Timo Penttila, Mika Aurela, Tuomas Laurila, Annalea Lohila

Summary: The wide-spread harvesting of forests on drained peatlands in Finland has raised concerns about its impact on carbon dioxide emissions and climate change. A study conducted in a mature peatland forest in southern Finland compared the impact of clear-cutting and partial cutting on CO2 exchange. The results showed that partial cutting resulted in significantly lower CO2 emissions in the short term, while clear-cutting continued to be a significant source of CO2 emissions throughout the measurement period. It was also found that the forest floor lost carbon both before and after the cuttings.

Agroforestry reclamations decreased the CO2 budget of a coastal wetland in the Yangtze estuary

Guishu He, Kaiyun Wang, Qicheng Zhong, Guilian Zhang, Cecil Konijnendijk van den Bosch, Jiangtao Wang

Summary: The study investigates the response of CO2 budget in coastal wetlands to agroforestry reclamations. The results show that agroforestry conversions substantially decrease the CO2 fixation service by changing the ecosystem's structure and function, with wetland vegetation productivity decrease being the main reason. The interannual variability of NEE is primarily attributed to functional changes rather than meteorological variations, suggesting the importance of wise land-use policy and management measures in reclaimed coastal areas for global warming mitigation.

Summary: Peatlands are important in storing soil carbon for long periods of time. This study focused on assessing the CO2 balances of a temperate peatland and the factors affecting these fluxes. The peatland was found to be a CO2 sink, but with extreme variations in different years. Seasonal data showed stronger correlations with biophysical variables than annual fluxes. Additionally, warmer spring and hotter summer temperatures were found to have different impacts on net ecosystem production. The study suggests that global warming negatively affects CO2 balances in temperate peatlands.

Summary: Northern peatlands are one of the largest natural sources of methane in the global methane budget. Understanding the processes of methane production and fluxes in these peatlands is crucial for reducing uncertainty in quantifying methane flux. A methane model embedded in the ORCHIDEE-PEAT land surface model was used to calibrate and evaluate methane emissions in various peatland sites. Results show that methanogenesis is sensitive to temperature and substrate availability in the top soil layers. Methane emissions were underestimated when using single site optimization of model parameters and overestimated when using multi-site optimization.
