In China, the Yangtze River is a typical case with decreased sediment load and stable streamflow (Guo et al., 2019). Due to the intensified construction of large hydropower dams, the sediment reaching its delta continued to decrease (Dai and Lu, 2014), and the same changes also were observed in the Pearl River (Liu et al., 2014; Wu et al., 2020).

As a result, consumption attained the peak level of $3.1B; …
For example, in 2000, Chinese authorities banned sand mining in the Yangtze River after extraction had caused the collapse of bridges and riverbanks. 12 However, this led to the massive expansion of sand mining in Poyang lake, which is 300 miles up the Yangtze river from Shanghai. Poyang is China's largest freshwater lake and an important ...

In 2019, coal consumption accounted for 57.7 percent of total energy consumption, but this was already a decrease of 10.8 percentage points from 2012; the consumption of so-called clean energy (natural gas, hydropower, nuclear power, and wind power) accounted for 23.4 percent of total energy consumption, an increase of 8.9 …
Natural Sand Imports in China. In 2022, supplies from abroad of natural sands decreased by -88.6% to 575K tons for the first time since 2018, thus ending a three-year rising trend.
Approximately 85% existing buildings consume natural sand. Every year over 10.5 billion tons of river sand are used in concrete and mortar all over the world [3, 4]. After decades of rapid development of the construction industry, the total amount of construction industry in China has gradually stabilized.

Food consumption has resulted in great carbon emissions in recent years. China has been facing the new mitigation challenge of carbon emissions with its emerging middle-income groups, especially in urban areas. This paper analyzes and predicts carbon emissions from food consumption (CEFC) of middle-income groups in the Yangtze River Economic Belt …
China has over 1320 freshwater fish species, 877 of which are endemic. In recent decades, over-exploitation and landscape pressures have threatened them and led to a severe aquatic biodiversity crisis. In response, large-scale fishing bans have been promulgated to protect freshwater biodiversity in major Chinese rivers since the early 1980s. Here, we present the …
