“…In a report by the National Aeronautics and Space Administration (NASA), it was noted that China accounted for 25% of the global net increase in leaf area from 2000 to 2017, mainly as a result of afforestation and agricultural activities 6 . These studies have revealed the characteristics and causes of changes in greening at a global and national level; however, greening and its drivers vary significantly at a regional level due to environmental differences and socioeconomic development 7 – 9 . To implement ecological conservation and rehabilitation measurements, it is necessary to understand the spatiotemporal patterns and drivers of greening at a regional scale 10 .…”

China accounts for 25% of the global greening. There are temporal and spatial differences of China’s greening and intrinsic driving forces. Thus, it is crucial to determinize the contributions of human activities and climate change on greening at region scale. The Beijing–Tianjin–Hebei Region (BTHR) is one of the most active areas with human activities in China. It is necessary to explore negative or positive impacts of human activities on the regional greening or browning under climate change. A time series of annual vegetation coverage from satellite data was selected to quantify regional greening in the BTHR from 2000 to 2019 and their responses to climate change and human activities. Results showed generally widespread greening over the last 20 years at an average increased rate of 0.036 decade−1 in vegetation coverage (P < 0.01). Overall warmer and wetter climate across the BTHR were positively correlated with regional greening. The positive effects of human activities on greening accounted for 48.4% of the BTHR, especially the benefits of ecological restoration projects and the agricultural activities. Increases in vegetation coverage had resulted from the combined effects of climate change and human activities. Climate change had a stronger influence on vegetation coverage than human activities. Contributions of climate change to greening and browning was about 74.1% and < 20%, respectively. The decrease in vegetation coverage was mainly the results of the inhibition of human activities. More detailed socioeconomic and anthropogenic datasets are required for further analysis. Further research consideration would focus on the nonlinear responses of vegetation to climate change.

a b s t r a c tCheck dams have been widely used globally as human introduced structures for watershed management for various purposes. However, the effects of these structures for carbon retention have been scarcely considered and quantified. This research formulated a simple approach in estimating the carbon retention effects of check dams in Yan'an prefecture of the Loess Plateau region of China based on check dam inventory data and benefit transfer approach. Results indicated that the large and medium sized check dams had retained about 42.3 million tons of soil organic carbon (SOC) with a high spatial variability. This is a significant amount similar to about 1.48% of the SOC stored in the 0-40 cm soil layer across the whole Loess Plateau or roughly 4% of the estimated carbon emission from fossil fuel in China in 2000. Total volume of check dam is the most important influencing factor for carbon retention effects at both check dam and county-levels. Years after construction is also a significant factor at check dam level. The numbers of check dams and land use as well as topographical factors have impacts on the respect of check dam carbon retention of varied significance at the county-level. The effectiveness of carbon retention decreased from north to south. The results of this research can be used as important decision support for check dam development planning at the local context. This research also revealed the scientific worthiness in quantifying the carbon retention effects concerning the relationships between soil erosion and carbon cycling. On this respect, process-based monitoring and research are urgently in need.
