Summary: Remote sensing methods offer a promising opportunity to monitor CO2 exchange in peatland ecosystems at large scales. The study developed empirical models for CO2 balance, GPP, and ER using satellite data and showed high agreement with field data for GPP and ER. Further research is needed to investigate sources of spatial and temporal variation in CO2 fluxes.

Summary: The frequency and extent of wildfires in the Arctic have been increasing due to climate change. In this study, researchers conducted experiments in West Greenland to investigate the long-term impacts of climate warming on post-fire carbon dioxide exchange in arctic tundra ecosystems. They found that fire increased soil organic phosphorus concentrations and burned areas remained a net CO2 source five years after the fire. However, with four to five years of summer warming, the burned areas turned into a net CO2 sink.

Summary: Carbon emissions in agriculture are significant in climate change. Modeling studies enable investigation of climate change impact on crops, accounting for soil organic carbon feedbacks and CO2 concentrations. Crop models need to properly consider CO2 exchanges in crop rotations. The model accurately simulates CO2 fluxes in a long-term and diversified crop rotation.

Summary: Climate change is altering the growing seasons of plants, affecting species performance and biogeochemical cycles. The timing of autumn leaf senescence in Northern Hemisphere forests is uncertain, but early-season and late-season warming have opposite effects on leaf senescence, with a reversal occurring after the summer solstice. Increased temperature and vegetation activity before the solstice led to an earlier senescence onset, while warmer post-solstice temperatures extended senescence duration. These changes in leaf senescence can impact growing-season length and forest productivity in the Northern Hemisphere.

Summary: In a replicated experimental study in loblolly pine plantations, it was found that soil heterotrophic CO2 efflux responds differently than net primary productivity to fertilization and drought treatments, leading to divergent responses of net primary productivity and net ecosystem production. The responses of net primary productivity and soil heterotrophic CO2 efflux to fertilization combined to increase net ecosystem production significantly under drought treatment.

Summary: The study reveals that India is a net carbon sink with a NEE of -0.16 +/- 0.02 PgC yr-1 from 2011-2020, as calculated using satellite data and a model. It is found that Gross Ecosystem Exchange contributes -0.47 +/- 0.02 PgC yr-1 and Respiration contributes 0.31 +/- 0.01 PgC yr-1 to NEE. The post-monsoon season shows the highest biospheric CO2 absorption, while the pre-monsoon season shows the lowest.

Summary: Most tundra carbon flux modeling uses leaf area index (LAI) to estimate fluxes, but this method does not consider the influence of tundra canopy structure. By adapting an NDVI-based model and incorporating the 3D structure derived from structure from motion (SFM), this study shows that even simple tundra canopy structure can significantly impact carbon fluxes. The study found that SFM-derived estimates of gross primary productivity (GPP) were lower and net ecosystem exchange (NEE) was higher compared to estimates based on LAI alone.

Summary: Peatland ecosystems act as effective long-term carbon sinks, but climate changes could influence CO2 fluxes and the fate of carbon stored in these ecosystems remains uncertain. While most studies on peatland carbon fluxes have focused on high latitude sites, information on peatlands in temperate regions is scarce, despite the increasing threats from human activities. To address this knowledge gap, we investigated CO2 fluxes in an alpine peatland using light and dark incubations. We found that water table levels and photosynthetic radiation were the main drivers of ecosystem respiration and gross primary production, respectively, while net ecosystem CO2 exchange showed greater variation throughout the growing season. The interactions between drivers, including soil temperature and moisture, as well as vegetation type and plant functional diversity, played a crucial role in influencing CO2 fluxes. The joint variation of atmospheric and edaphic factors also regulated a significant part of the variation in CO2 emission and uptake processes. To accurately understand and predict CO2 dynamics in alpine peatlands, it is important to consider the interplays among ecological factors, especially in the context of anticipated climate and vegetation changes.

Summary: Thinning has a modest impact on the C balance of silver birch stands, resulting in decreased net ecosystem production but still maintaining as C sinks, mainly due to reduced tree biomass. Thinning increased C accumulation in herbaceous plants but did not compensate for the lower C accumulation by trees. Overall, thinning did not significantly affect soil respiration fluxes.

Summary: This study compares tree-ring based estimates with eddy-covariance data to estimate annual ecosystem production for jack pine and aspen plots in the boreal forest of Canada. The correspondence between tree-ring and eddy-covariance estimates was better for jack pine than aspen. The discrepancies in C flux estimates could be attributed to factors such as stand density and carbon use efficiency.

Summary: This study shows that the depth of the water table is the main factor influencing greenhouse gas fluxes in peatlands. By lowering the water table depth by 10 cm, emissions of CO2 and CH4 can be reduced by the equivalent of at least 3 tonnes of CO2 per hectare per year, until the water table depth is less than 30 cm.

Summary: Coastal wetlands are important ecosystems that store a large amount of carbon and have high productivity. However, they are threatened by various natural and human disturbances. By studying a coastal forested wetland, we found that climate and hydrologic factors play a significant role in carbon fluxes and balance. Air temperature, net radiation, and groundwater table depth have a strong impact on gross primary productivity, ecosystem respiration, and net ecosystem carbon exchange.

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.

Summary: The study used a simulation model to analyze the impact of continuous-cover forestry on CO2 and CH4 emissions in nutrient-rich drained peatland sites in southern Finland. Results showed that the peatland forest acted as a carbon sink with low and medium harvesting intensities, but became a carbon source with high harvesting intensities due to increased soil methane emissions and decreased tree production. The simulations highlight a significant trade-off between maintaining carbon in drained peatland forests and generating harvest revenues.

Summary: The patterned microtopography of subarctic mires creates varied environmental conditions, leading to spatial variation in carbon dynamics, including CO2 and CH4 exchange, among different plant community types (PCTs). The CO2 and CH4 emissions from different PCTs show strong spatial variation, influenced by water table level and vegetation composition. Overall, the carbon balance of the fen tends to remain stable despite variations in CO2 and CH4 emissions from different PCTs and years.

Summary: This study investigates the impacts of water and heat stress on carbon uptake in China and explores the driving mechanisms of droughts using a machine learning model. The results show that droughts are mostly driven by atmospheric dryness, with precipitation, relative humidity, and temperature playing dominant roles. Water and heat stress have negative impacts on carbon assimilation, and drought occurrence is projected to increase significantly in the future. Improving ecosystem resilience to climate warming is crucial in mitigating the negative effects of droughts on carbon uptake.

Summary: This study proposes a method to partition evapotranspiration (ET) into its components in agroforestry systems. The method is based on water-carbon coupling theory and flux conservation hypothesis. The results show that the partitioned components agree well with measurements from other sensors. The study also finds that atmospheric evaporation demand and vegetation factors greatly influence the components of ET, and increased tree leaf area limits understory grass transpiration.

Summary: With the rapid increase of urbanization, evapotranspiration (ET) in urban forests has become increasingly important in urban hydrology and climate. However, there is still a large uncertainty regarding the factors that regulate ET in urban areas. This study investigates the temporal variations of ET in an urban forest park in Beijing using the eddy-covariance technique. The results show that daily ET is close to zero during winter but reaches 3-6 mm day-1 in summer. Daily ET increases with vapor pressure deficit (VPD) and soil water content (SWC). Monthly ET increases linearly with normalized difference vegetation index and shows a strong correlation with surface conductance (gs), while exhibiting saturated responses to increasing monthly precipitation (PPT). Annual ET ranges from 326 to 566 mm, and soil water replenishment through PPT from the previous year is responsible for the generally higher monthly ET in spring relative to PPT. Biotic factors and PPT seasonality play essential roles in regulating ET at different scales.

Summary: As climate change is expected to increase the intensity and frequency of extreme weather events, it is crucial to assess their impact on cropping systems and explore adaptation options. Process-based crop models (PBCMs) have improved in simulating the impacts of major extreme weather events, but still struggle to reproduce low crop yields under wet conditions. This article provides an overview of the yield-loss mechanisms of excessive rainfall in cereals and the associated modelling approaches, aiming to guide improvements in PBCMs.

Summary: Understanding the impact of climate on litterfall production is crucial for simulating nutrient cycling in forest ecosystems. This study analyzed a 14-year litterfall dataset from two subtropical forests in South China and found that litterfall was mainly influenced by wind speed during the wet season and by temperature during the dry season. These findings have potential significance in improving our understanding of carbon and nutrient cycling in subtropical forest ecosystems under climate change conditions.

Summary: Solar-induced chlorophyll fluorescence (SIF) has the potential to estimate gross primary production (GPP), but the quantitative relationship between them is not constant. In this study, a mechanistic model for SIF-based GPP estimation in evergreen needle forests (ENF) was developed, considering the seasonal variation in a key parameter of the model. The GPP estimates from this model were more accurate compared to other benchmark models, especially in extreme conditions.

Summary: Sustainable rice farming practices are urgently needed to meet increasing food demand, cope with water scarcity, and mitigate climate change. Traditional farming methods that prioritize a single objective have proven to be insufficient, while simultaneously optimizing multiple competing objectives remains less explored. This study optimized farm management to increase rice yield, reduce irrigation water consumption, and tackle the dilemma of reducing GHG emissions. The results suggest that the optimized management can maintain or even increase crop yield, while reducing water demand and GHG emissions by more than 50%.
