Abstract:

Exploring the coupling and coordination laws between agricultural water poverty and food production vulnerability is of great significance for the Fenhe River basin, which faces water shortages and poor grain production capacity. This study constructed evaluation index systems for agricultural water poverty and food production vulnerability in the Fenhe River basin. It calculated the coupling coordination degree between the two from 2007 to 2021 and identified the spatial-temporal patterns and influencing factors of their coupling coordination. The results showed that: (1) During the study period, agricultural water poverty in the Fenhe River basin significantly eased, with the water poverty index rising from 0.349 to 0.384. Spatially, the upstream region experienced the most severe agricultural water poverty (0.334), followed by the midstream region (0.356), and the downstream region (0.385). Additionally, the western region showed more severe water poverty than the eastern region. (2) There was no significant difference in food production vulnerability in the Fenhe River basin during the study period. Spatially, the upstream region exhibited the most severe food production vulnerability (0.348), followed by the midstream region (0.379), and the downstream region (0.419). (3) During the study period, there was no significant change in the coupling coordination degree between agricultural water poverty and food production vulnerability in the Fenhe River basin. Overall, the coupling coordination degree exhibited a spatial distribution characterized by "low in the north and high in the south", supplemented by "low in the west and high in the east". (4) The dominant factors affecting the coupling coordination degree between agricultural water poverty and vulnerability of food production in the Fenhe River basin are water consumption per unit area of grain sowing, pesticide application intensity in grain production, level of mechanization in grain production, and proportion of grain crop sowing area, etc. Additionally, there is an enhancing effect when these factors interact with each other.

Key words: agricultural water poverty, grain production vulnerability, spatial-temporal coupling, driving factors, Fenhe River basin
