The impact of a bias-correction approach (delta change) applied directly to hydrological model output when modelling the severity of ice jam flooding under future climate scenarios

Apurba Das et al.

Summary: Assessing the impact of future climate on the severity of ice jam floods is crucial for flood mitigation strategies. Different methods of calculating climate change signals can lead to varied results in assessing the frequency and severity of future ice jam events. Careful interpretation and selection of methods are necessary.

Relative Contributions of Climate Change and Human Activities on Vegetation Productivity Variation in National Nature Reserves on the Qinghai-Tibetan Plateau

Jia Zhou et al.

Summary: This study analyzed the vegetation dynamics and driving factors of 42 national nature reserves on the Qinghai-Tibetan Plateau. The results showed that climate change and human activities have significant contributions to the variation in vegetation dynamics. Understanding these impacts is important for policymakers.

Appropriated protection time and region for Qinghai-Tibet Plateau grassland

Shuan Qian et al.

Summary: The grassland in the Qinghai-Tibet Plateau accounts for a large proportion of the land area and is sensitive to climate. Research shows that water deficit is most severe in spring and should be focused on in central and western regions.

Assessment of the impact of LUCC on NPP and its influencing factors in the Yangtze River basin, China

Hongfei Yang et al.

Summary: The study analyzed the impact of land use and land cover changes on vegetation net primary productivity in the Yangtze River basin from 2001 to 2018, showing that land changes led to an increase in NPP. Forest area increased the most while grassland area decreased the most.

Climate Variability Rather Than Livestock Grazing Dominates Changes in Alpine Grassland Productivity Across Tibet

Meng Li et al.

Summary: The research indicated that in the past few decades, Tibet's climate has become warmer and wetter, while grazing intensity has decreased. The aboveground net primary production (ANPP) has increased in most sites, from an average of 27.0 g C m(-2) during 2000-2008 to 28.4 g C m(-2) during 2009-2017. ANPP was positively correlated with annual temperature and precipitation, but negatively correlated with grazing intensity. Random forest modeling showed that precipitation (29.0%) had a much greater impact on grassland ANPP than grazing intensity (14.5%), highlighting precipitation variability as a key factor for the increase in alpine grassland ANPP across Tibet.

Reducing human activity promotes environmental restoration in arid and semi-arid regions: A case study in Northwest China

Chuanhua Li et al.

Summary: This study assessed the impacts of human activities on NPP in a typical arid and semi-arid region, proposed a method to calculate PNPP based on LAI, and found that reducing human activities can significantly promote environmental restoration.
