Lakes including reservoirs are sensitive to global environmental change and human activities in the basin. They sentinels regulators of regional climate. Meanwhile, lakes important constituent “landscape, forest, farmland, lake, grassland sand” life community. Remote sensing monitoring showed that there were 2670 (≥1 km2) with a total water area 80662.4 km2, 5156 39697.1 km2 China 2020. Water Statistical Yearbook 2021 number storage capacity completed increased from 86822 98566, 416.9 930.6 km3 1980 Therefore, is 120359.5 but only accounting for 1.25% China’s land area. Although their proportion very limited, play vital role ensuring ecological civilization construction promoting economic social development Unfortunately, importance service values seriously underestimated lack real quantification. this study systematically explores quantifies services seven different perspectives.

Meeting the United Nations' (UN's) 17 Sustainable Development Goals (SDGs) has become a worldwide mission. How these SDGs interrelate, however, is not well known. We assess interactions between for case of water pollution by nutrients in China. The results show 319 clean (SDGs 6 and 14) other SDGs, which 286 are positive (synergies) 33 negative (tradeoffs) interactions. analyze six scenarios China accounting cobenefits control using large-scale quality model. consider that benefit from synergies avoid tradeoffs. Our effective requires SDGs. For instance, combining improved nutrient management, efficient food consumption, climate mitigation simultaneously meeting 14 as food, cities climate. study serves an example assessing SDG environmental policies regions world.

Efficient n = O bond activation is crucial for the catalytic reduction of nitrogen compounds, which highly affected by construction active centers. In this study, was achieved a single-atom catalyst (SAC) with phosphorus anchored on Co center to form intermediate N-species further hydrogenation and reduction. Unique phosphorus-doped discontinuous sites exhibit better performance than conventional N-cooperated sites, high Faradic efficiency 92.0% maximum ammonia yield rate 433.3 μg NH4·h-1·cm-2. This approach constructing environmental through heteroatom modification significantly improves atom will guide design future functional SACs wide-ranging applications.

Abstract Eutrophication is a major global concern in lakes, caused by excessive nutrient loadings (nitrogen and phosphorus) from human activities likely exacerbated climate change. Present use of indicators to monitor assess lake eutrophication restricted water quality constituents (e.g. total phosphorus, nitrogen) does not necessarily represent environmental changes the anthropogenic influences within lake’s drainage basin. Nutrients interact multiple ways with climate, basin conditions socio-economic development, point-source, diffuse source pollutants), systems. It therefore essential account for complex feedback mechanisms non-linear interactions that exist between nutrients ecosystems assessments. However, lack set holistic understanding challenges such assessments, addition limited monitoring data available. In this review, we synthesize main freshwater basins only include but also sources, biogeochemical pathways responses emissions. We develop new causal network (i.e. links indicators) using DPSIR (drivers-pressure-state-impact-response) framework highlights interrelationships among provides perspective dynamics basins. further review 30 key drivers pressures seven cross-cutting themes: (i) hydro-climatology, (ii) socio-economy, (iii) land use, (iv) characteristics, (v) crop farming livestock, (vi) hydrology management, (vii) fishing aquaculture. This study indicates need more comprehensive systems, guide expansion networks, support integrated assessments manage eutrophication. Finally, proposed can be used managers decision-makers realistic targets sustainable management achieve clean all, line Sustainable Development Goal 6.

Abstract Climate change, population growth, and agricultural intensification are increasing nitrogen (N) inputs, while driving the loss of inland water bodies that filter excess N. However, interplay between N inputs body dynamics, its implications for quality remain poorly understood. Analyzing data from 1995 to 2015 across China, here, we find a 71% reduction in area small (<10 4.5 m 2 ) (SWB), primarily high-N-input regions. Preferential SWBs, most efficient nutrient filters, places 42% China at high risk due declining SWB density. Currently, removal by is 986 kilotonnes year −1 , but restoring 2.3 million hectares could increase 21%, compared just 5% equivalent restoration large bodies. Targeted crucial improving mitigating pollution China.
