China’s Water Footprint on Urban and Rural Food Consumption: A Spatial–Temporal Evolution and Its Driving Factors Analysis from 2000 to 2020

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The study is closely relevant to contemporary challenges of food security and water resource management. It analyze the critical issue of water scarcity in relation to the growing demand for food, especially in a densely populated and rapidly developing country like China. This study focuses on the regional heterogeneity of the water footprint of food consumption and its potential drivers in urban and rural China. Specifically, this study investigates the spatial and temporal variations in food consumption patterns and associated water footprints in urban and rural areas of China over the period from 2000 to 2020. Based on these water footprint datasets, a random forest model is used to further investigate the key drivers of food water footprint changes in urban and rural areas. This dual focus on urban and rural dynamics offers a more comprehensive understanding of the issue. The study influences the promotion of balanced food intake among urban and rural residents in China, reducing water resource pressure caused by food, and optimizing water resource utilization.

Given the research content of the article, it is recommended for acceptance. This manuscript explored some issues, while there are still areas that need to be improved.

Abstract：

The abstract provides a good overview but could be more succinct. Focus on highlighting the most significant findings and the unique contribution of the study to the field. It could be beneficial to briefly mention the methodological approach  to give readers a clearer understanding of the study's rigor​​.

Methodological Detailing:

The methodology section, particularly the description of the random forest model, would benefit from more detailed explanations for readers who may not be familiar with this approach.

Language and Grammar:

Minor grammatical and punctuation errors should be corrected for professionalism and readability.

Overall, the article provides valuable insights into the changing patterns of food consumption and their environmental impacts in China.

These suggestions aim to enhance the clarity, depth, and impact of the article, thereby making it a more valuable contribution to the field.
