Summary: In this study, the daily SPEI algorithm was used to project global drought conditions during 2016-2100 based on the CMIP6 data. The influence of climate factors on drought was explored through partial correlation analysis. The results show that drought conditions projected by CMIP6 are similar under different models, but vary widely across regions. Most regions around the world are expected to experience increasingly severe drought conditions in the future.

Summary: Drought, exacerbated by land degradation and climate change, is a significant natural disaster. Monitoring and evaluating droughts are crucial for managing regional drought conditions and protecting the environment. In this study, various remote sensing-based drought indices were used to investigate the spatiotemporal variations of meteorological and agricultural droughts in Iran between 2000 and 2021. The results showed that the combined remote sensing-based drought indices had higher correlation coefficients with in situ drought indices.

Summary: This paper quantifies the uncertainty of standardized drought indices (SPI and SPEI) based on an Austrian dataset and finds that the computational variations of these indices lead to highly variable results. The choice of distribution and observational window are the main sources of uncertainty, while parameter estimation method and GOF-tests have almost no effect. Overall, the uncertainty of standardized drought indices is substantial.

Summary: This study explored the desertification dynamics and drivers on the Mongolian Plateau using remote sensing imagery and dataset. The results showed that the desertification in the East Ujimqin Banner went through a process of reversion, development, and mild development, while desertification in Mongolia mainly concentrated in Matad County. The intensity of desertification dynamics in the study area showed a decreasing trend, and the interaction between natural and anthropogenic drivers could enhance the explanatory power. These findings provide a scientific basis for desertification control and ecological protection on the Mongolian Plateau.

Summary: The impact of tropical cyclones on the gross primary production (GPP) of mangrove ecosystems is significant, but there is a lack of scientific research on the effects of large-scale weather events such as cyclones on mangrove ecosystem GPP. In this study, the subtropical Hainan Island mangrove ecosystem, which experiences more than two cyclones per year, was chosen as the research area. The study evaluated the loss and recovery of mangrove ecosystem GPP after direct-impact cyclones using a vegetation photosynthesis light-use efficiency model based on eddy covariance observation data. The findings showed that cyclones affect mangrove ecosystem GPP through photosynthetic area and rate, with the rate recovering before the area. The loss of GPP is inversely proportional to the distance to the center of the cyclone and the coastline. Factors such as canopy height, diameter at breast height, and tree stand aspect significantly influence the response of mangrove ecosystem GPP to cyclones. However, further analysis is needed to understand the response variations based on mangrove community compositions, soil conditions, planting densities, cyclone frequencies, and intensities. This study is expected to provide technical and data support for the protection of blue carbon in a subtropical island mangrove ecosystem in response to extreme events and post-disaster recovery.

Summary: The frequency and intensity of fires are increasing due to warmer temperatures, increased droughts, and changes in climate-induced fuel distribution. Vegetation is moving to higher latitudes or elevations as a response to global warming. This movement of vegetation northward has led to an increase in fires in the Mongolian Plateau, particularly in the Dornod, Sukhbaatar, and Kent provinces. The occurrence of high probability dead fuel index (DFI) is distributed in northern Mongolia, the China-Mongolia border area, and the meadow-steppe region of the Greater Khingan Mountains. These findings indicate that the northward movement of vegetation due to climate change poses a challenge as future warming can spread fires northward.
