Summary: The study investigated the effects of forest N fertilization on soil CH4 and N2O fluxes in young spruce stands in Sweden. Results showed that fertilization can influence the flux of these greenhouse gases, but using commercial NP or NPK fertilizers equivalent to 150 kg ha(-1) of N did not significantly alter the fluxes.

Summary: This study evaluated the impact of nitrogen fertilizer application on soil CO2, CH4, and N2O emissions during different stages of banana cultivation. The results showed that nitrogen fertilization increased N2O emissions, especially in young banana plantations. Additionally, banana plantations showed lower CH4 uptake compared to the forest remnant. Therefore, reducing nitrogen application rates should be considered in young banana plantations due to the negative effect of N2O emissions.

Summary: The study found that clear-fell harvesting had significant effects on the soil GHG fluxes of CO2, CH4, and N2O, mainly due to the increases in soil temperature and moisture, as well as the removal of trees and carbon input. This shows the importance of multi-year monitoring to accurately assess the impact of clear-fell harvesting on the GHG balance in managed forests.

Summary: Land-use change in tropical peatlands significantly affects methane (CH4) and nitrous oxide (N2O) emissions, with oil palm plantations having a much higher GHG budget compared to peat swamp forests. Water table level and soil water-filled pore space were identified as key drivers of CH4 and N2O flux variation. Forest degradation and conversion to oil palm resulted in a disastrous atmospheric impact.

Summary: This research addresses CO2, CH4, and N2O emissions in the EU from 2008 to 2018 and their contributing factors. The study finds that new state members are catching up with old state members in terms of technology innovation and N2O emissions mitigation in agriculture activities, although not all countries have achieved this. The results highlight the importance of addressing environmental aspects and developing innovative decoupling indexes in agriculture policymaking.

Summary: This study investigates the impacts of different residue manipulations on soil greenhouse gas (GHG) fluxes in a Chinese fir plantation. The results show that residue burning increases soil CO2 emissions, residue harvest slightly increases CO2 emissions in the first year but decreases them in the second year, and mulching after crushing treatment increases soil CO2 and N2O emissions. These findings are important for accurately estimating carbon and nitrogen fluxes in plantations.

Summary: The study found that biochar soil amendment can improve the survival and growth of planted pine trees, enhance biomass growth, and alter the composition of understory vegetation. However, biochar had little impact on the supply rates of main soil nutrients. Additionally, biochar did not significantly change overall N2O and CO2 emissions or CH4 uptake from the forest floor.

Summary: Airborne measurements provide an effective way to quantify urban emissions of greenhouse gases. The developed active AirCore system allows for high-precision and continuous measurements of multiple gas species. The results show that N2O emissions in the Rotterdam area are approximately three times larger than the Dutch inventory, while emissions in Groningen and Utrecht are not significantly different. CH4 emissions are not significantly different from the Dutch inventory for all three urban areas. This innovative aircraft-based sampling system is useful for quantifying GHG emissions from urban areas.

Summary: Streams and rivers are major sources of greenhouse gas emissions. While our understanding of individual gas flux drivers has improved, the lack of consistently collected samples hinders our ability to analyze the interrelationship between gas concentrations and their drivers. This study analyzed a dataset collected by the National Ecological Observatory Network, providing insights into the physical and biogeochemical drivers of greenhouse gas production in 27 streams and rivers across the United States. The results show that physical drivers such as temperature, stream slope, dissolved oxygen, and total nitrogen concentration strongly influence the concentrations of CO2 and CH4, while N2O is exclusively correlated with total nitrogen concentration.

Summary: A 5-year greenhouse gas exchange study of a intensively managed permanent grassland in Switzerland compared pre- and post-plowing GHG exchange, finding no memory effects on N2O and CH4 emissions but a considerable increase in CO2 uptake. The grassland acted as a carbon sink under usual management.

Summary: This study applied various footprinting approaches to comprehensively evaluate the environmental impacts and economic benefits of organic rice farming and conventional rice farming. The results showed that organic rice farming can mitigate greenhouse gas emissions, but has a lower yield compared to conventional rice farming. Despite the lower yield, organic rice farming has a higher economic return.

Summary: This study aimed to differentiate between drought and waterlogging stress in Prunus yedoensis based on growth and physiological indicators. The results showed that root growth significantly decreased under waterlogging stress, while drought stress led to a decrease in stem diameter. In addition, photosynthetic indicators decreased significantly under drought stress but started to decline from day 7 under waterlogging stress. Drought stress resulted in higher levels of leaf and root inorganic components, while waterlogging stress led to overall nutritional deterioration. Changes in photochemical reactions and vitality indices can serve as diagnostic indicators of drought or waterlogging damage.

Summary: This study examines the impact of converting forestland to agricultural land on soil organic carbon (SOC) stocks and soil erodibility in the Mae Chaem Basin, Chiang Mai Province, Thailand. The results show that the conversion to maize fields leads to a significant reduction in SOC stocks, while the replacement of maize fields with grassland and pumpkin tends to increase SOC stocks. Additionally, the study finds a positive correlation between silt concentration and soil erodibility, and a negative correlation between SOC and soil erodibility.

Summary: Simulation of future climate changes in the Ishikari River basin in Hokkaido, Japan was conducted using global climate models. The selected models showed a significant correlation with temperature measurements but did not accurately represent precipitation features. The findings suggest that the northern part of the basin is more likely to become hotter with heavier precipitation in the future.

Summary: The frequency and intensity of typhoons have increased due to climate change, resulting in widespread damage to forests. This study compared different forest damage estimation techniques and identified their respective advantages and suitable use cases. Machine learning classifiers achieved the highest accuracy in damage assessment, but required intensive computation and complex processing steps. The methods and findings presented in this study can aid stakeholders in implementing more effective forest damage monitoring after typhoons and extreme weather events in the future.

Summary: The study investigated soil properties and soil erodibility after fire in rotational shifting cultivation (RSC) practiced by hill tribes in Thailand. The results showed that soil nutrients and erodibility increased after burning and remained higher than pre-burning levels for at least 2 years. The levels of soil organic carbon and total nitrogen decreased after burning, and their recovery varied among different fallow fields.

Summary: This study aims to estimate the spatiotemporal variation in water runoff and soil loss in the Tokoro River watershed in Hokkaido, Japan. Simulation results showed that croplands, especially sloped croplands, were the primary source of stream sediment load. Soil loss mainly occurred in early spring and late summer, and surface runoff when the soil was frozen was considered an important driver of soil loss.

Summary: This study aims to investigate the impact of fire on soil properties and soil surface loss in rotational shifting cultivation, finding that older fallow fields tend to accumulate more soil organic carbon and soil organic nitrogen. The combustion of organic matter during the fire releases soil nutrients, leading to an increase in soil nutrients. The highest soil surface loss was observed 9 months after the fire on the upper slope. Slope also has a significant impact on soil properties.
