Abstract

fetched live from OpenAlex

Water is withdrawn, lost, consumed, polluted, returned, treated, reused, and traded between regions within the societal water cycle due to human activities, contributing to regional water stress. In this research, we aim to examine the impacts of the societal water cycle on water resources and explore strategies for reducing water stress in China. The results show that most provinces in China suffer from water quantity and quality stress. However, there is a significant potential to reduce water quantity stress by 36–79 % through reducing water loss and return flows. The return flows and water loss in the virtual export forms could be avoided to reduce virtual water export-induced quantity stress by 39–89 %. Agriculture and households’ return flows contribute 61–98 % to provincial water quality stress in China. The five sectors with the greatest potential to mitigate water quantity and quality stress are identified for each province, which could reduce quantity stress by 22–75 % and quality stress by 23–76 %. • Majority provinces in China suffer from both water quantity and quality stress • System thinking of societal water cycle is necessary for water stress assessment and mitigation • Water loss and return flows contribute to 36–79 % of water quantity stress • Agriculture and households' return flows contribute 61–98 % to provincial water quality stress • The top five sectors could mitigate quantity stress by 22–75 % and quality stress by 23–76 %

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
