Summary: This study explores the responses of greenhouse gas emissions to land use conversion or reversion. Results show that methane (CH4) and nitrous oxide (N2O) emissions respond positively to land use conversion, while carbon dioxide (CO2) emissions respond negatively to the changes from natural herb and secondary forest to plantation. The study also highlights the long-term impact of soil carbon on CO2 emissions after land use conversion.

Summary: Urea addition accelerates soil P cycling by promoting the transformation of refractory P(i) into less available P(i) fractions. Water addition counteracts the positive effect of urea on NH4F-P(i) in both the steppe and old field. The soil P(i) pool increases in farmland compared to steppe due to enhanced organic P mineralization.

Summary: Grasslands, the most extensive vegetation type in terrestrial ecosystems, play a crucial role in the soil phosphorus cycle. Nutrient addition and experimental warming have varying impacts on the global grassland ecosystem, affecting microbial biomass, litter phosphorus concentration, and available phosphorus. Environmental factors such as temperature, precipitation, and soil pH can also influence the soil phosphorus response to nutrient addition. Understanding the dynamic changes in soil microbial and enzyme activities is essential for predicting the future phosphorus cycle in grassland soils.

Summary: Afforestation significantly increases soil organic carbon, total nitrogen, and total phosphorus stocks. Factors such as land use system, climate zone, and forest type have substantial impacts on soil properties. The age of forests plays a crucial role in the accumulation of soil organic carbon and nitrogen.

Summary: The study addresses methodological principles for land use development scenario modeling assumed for use in processes of GHG accounting and management, with a focus on Lithuania. Calibration of the modeling approach using historical land use data indicated a high prediction accuracy for forest and built-up land, supporting suggestions for key measures to improve the GHG balance and carbon stock changes in the country.

Summary: The study examined the impact of climate change and different land-use intensities on plant-soil communities in mountain pastures. Results showed that under warming conditions, the production of plant-soil communities increased, with a greater effect seen under intensive management. Communities under extensive management exhibited higher C:N ratios and greater production stability under drought conditions.

Summary: Soil carbon (C), nitrogen (N), and phosphorus (P) contents and their stoichiometric ratios in response to agricultural use were generally similar across the four climate zones, with P increasing and C:N:P ratios decreasing. More intensive agricultural practices and stronger biological and geochemical processes in warmer and wetter zones led to more pronounced differences in soil C, N, and P contents and their stoichiometric ratios among land-use types, compared to cooler and drier climates.

Summary: Grazing exclusion is a widely implemented strategy for restoring degraded grassland ecosystems and increasing carbon stocks. This study analyzed data from 199 experiments to understand the temporal responses and factors influencing plant and soil carbon stocks following grazing exclusion in different grassland ecosystems. The results showed that plant biomass carbon stocks and soil organic carbon stocks decreased exponentially or rationally with years since enclosure. Grazing exclusion had positive effects on aboveground biomass carbon, but the effects on belowground biomass and soil carbon were influenced by climate, initial carbon levels, and grazing exclusion duration. The response of carbon stocks to grazing exclusion stabilized after approximately 40 years, with soil carbon sequestration showing a lagged pattern compared to plant biomass carbon. The study highlighted the effectiveness of grazing exclusion in regions with low carbon content and non-water limited conditions. However, it might not be an effective measure to increase soil organic carbon stocks in water-limited areas like desert grasslands.

Summary: This study evaluated the historical and future land use and land cover change and its impact on grassland carbon storage in northern China. The results showed a drastic decrease in grassland area before 2005, while agriculture and barren land increased. Land use change resulted in significant ecosystem carbon loss, primarily in agro-pasture areas. After 2001, the region was projected to be a carbon sink due to the positive impact of land use change.

Summary: Efficient and targeted use of phosphorus is crucial in avoiding environmental issues caused by population growth and increased food demand. Global projections indicate a significant amount of new arable land will be needed by 2050, but with proper phosphorus management, cropland expansion can be avoided while improving productivity levels.

Summary: Land-use change affects the uptake or release of carbon (C), nitrogen (N), and phosphorus (P) in soils. Forest to cropland conversion reduces soil organic C (SOC) and total N (TN), while forest to grassland conversion increases both slightly. Conversely, cropland to forest conversion increases SOC and TN. Changes in phosphorus (P) are influenced by fertilizer application rates. Changes in SOC, TN, and TP and their stoichiometries are also influenced by temperature and rainfall, but no general patterns emerge. Forestation with deciduous trees increases SOC, TN, and TP, while forestation with conifers reduces them. These findings suggest the importance of nutrient availability in achieving maximal C storage.

Summary: The interactions between nitrogen and phosphorus play a crucial role in plant growth and carbon sequestration in ecosystems. Adding phosphorus to soil increases the total nitrogen pool and accelerates nitrogen cycling processes. Additionally, phosphorus supply enhances soil organic carbon content and promotes soil carbon sequestration.

Summary: The study found that nitrogen (N) addition significantly promoted plant aboveground biomass in alpine grassland ecosystems, with a stronger response in restored grasslands compared to natural grasslands. In addition, the results suggested that climate warming could enhance plant biomass allocation to belowground under ongoing N deposition and highlighted the importance of precipitation for plant growth and aboveground biomass accumulation in restored alpine grasslands.

Summary: The study demonstrated that alpine grasslands are more sensitive to SOC changes during grassland transformation. The initial SOC stock of alpine grasslands was about 3 times that of temperate grasslands, and the SOC loss rates of alpine grasslands were significantly higher than temperate grasslands. The results suggest that attention should be paid to alpine grasslands in order to maintain their carbon sink potential and protect existing soil carbon storage.

Summary: Reducing CO2 emissions is crucial for the UK to achieve its net zero policy objective. By leveraging climate change and land use change, suitable bioenergy crops can be strategically deployed to enhance energy production and carbon sequestration. This study evaluates the potential of bioenergy crops and their response to changing climate in the upper River Taw observatory catchment in southwest England. The results indicate that a warming climate positively impacts the production of all crops considered, with colder areas benefiting more in terms of biomass. Additionally, converting permanent grassland to perennial bioenergy crops can increase production and carbon sequestration potential.
