Grazing behavior is a key factor that affects the sustainable development of the grassland social-ecological system. Grazing behavior is not only restricted by policies but also affected by the awareness of the herder of the grassland environment. To explore the influencing factors and mechanism behind grazing behavior, Yanchi County of Ningxia, a typical area of the “returning grazing land to grassland” project in Northwest China, was selected as a study area. Based on the consciousness-context-behavior theory, a questionnaire was designed, and 305 households were surveyed. Analysis of structural equation model results show: (1) the environmental sensitivity of herders and their satisfaction with the compensation mechanism regulated grazing behavior. When herders were more dependent on grassland, they were more willing to graze. (2) The grassland dependence, environmental sensitivity of herders, and herders’ satisfaction with the compensation mechanism had a significant interaction effect on grazing behavior. (3) Family livelihood diversification and the number of young and middle-aged laborers had a significant moderating effect on grassland dependence and grazing behavior. These findings are of vital importance for the government to formulate policies to promote the sustainable development of grasslands.

Building sufficient recycled water infrastructure is an effective way to solve problems related to water shortages and environmental degradation, and is of great strategic significance for saving resources, protecting the ecological environment, and promoting sustainable social and economic development. Although recycled water is environmentally friendly, the public is still skeptical about its use, which has led to the failure of a large number of recycled water infrastructure investments; therefore, increasing the public’s willingness to re-use is critical for the construction of recycled water infrastructure. To identify the influence mechanism of user comments on public re-use behaviors, we conducted an eye-tracking experiment in China. The results demonstrated that (1) perceived usefulness, perceived quality, and perceived risk have significant impacts on the public’s willingness to buy; (2) user reviews can enhance the public’s perceived usefulness of recycled products and increase their willingness to buy; and (3) in the process of consumption, the public tends to pay attention to negative reviews, where user reviews alter the perceived risks and perceived prices of recycled products, thereby affecting the willingness to buy of consumers. This study provides a scientific reference for the construction of recycled water infrastructure and the further promotion of recycled water.

The public’s rejection of recycled water has seriously hindered the promotion of recycled water. Individual intention and decision-making behavior will be affected by group decision-making behavior. To clarify the interaction mechanism of the public’s intention to reuse recycled water from the perspective of group decision-making, this study used an eye-movement experiment with a recycled water consumption scenario simulation to obtain the influencing factors and data related to purchase decisions and used the ABM (agent-based modeling) method to simulate the interaction effects of the group’s intention to reuse recycled water in a combination of three influencing factor scenarios: sales volume, quality evaluation, and environmental evaluation on the Netlogo platform. The results showed that (1) quality reviews have a significant effect on the intention of the group to reuse recycled water, followed by sales, and environmental reviews have the worst effect; (2) in the two-factor interaction, the intention of the group to reuse recycled water was significantly improved, and the public’s intention to reuse recycled water was highest under the influence of good quality reviews and high sales; and (3) under the combined influence of the three factors of high sales, good quality reviews, and good environmental reviews, the public’s intention to reuse recycled water was the highest, but the effect was slightly different from the influence of two factors: good quality reviews and high sales. This study aimed to provide a scientific basis for the promotion policy of recycled water reuse.
