This study explores the impacts of bicycle sharing and the satisfaction of tourists using such services. Using Hangzhou as a case study and data derived from 552 tourist surveys, a structural equation model of the satisfaction of tourists using bicycle sharing is constructed. Six perceptual factors were identified as sources of tourist satisfaction arising from the use of a cycle sharing scheme, namely: cycle accessibility, perceived risk, environmental awareness, psychological benefit, managerial action, and perceived rule adherence. Of these, tourists’ psychological benefits accounted for the highest proportion of tourists’ satisfaction, followed by easy access to cycles, environmental awareness, and management effectiveness. Rule adherence and risk perception exerted relatively less influence. A significant positive correlation was noted between usage satisfaction and environmental awareness, perceived rule adherence, ease of access to cycles, psychological benefit, and managerial action. However, the research hypothesis that perceived risk affects tourist satisfaction was not supported by the study findings. Finally, this study suggests some bicycle sharing management strategies and recommendations to enhance tourists’ usage satisfaction.

In recent years, there has been widespread concern regarding the carbon footprint (CF) of food waste due to the key impact of CF on climate change, particularly as China’s food waste is rising with its economic development. China has the largest scale of higher education in the world, and the amount of food waste in university canteens is considerable and cannot be ignored. This study attempts to assess the carbon footprint (CF) of food waste at Chinese universities for the first time based on a national survey. It is estimated that 1.55 million tons of food were wasted in Chinese university canteens in 2018, based on 9,192 samples covering 29 provinces in China. The associated CF was 2.51 Mt CO2eq. The top two food categories contributing to the total CF were meat and grains, accounting for 46.28% and 36.52%, respectively. Furthermore, the location of the university was significantly associated with the CF of plate waste. It also indicated that household income, meal satisfaction, sex, education, meal days, and food-saving campaigns were important factors influencing the CF of food waste. This study highlights areas that can help reduce the environmental impact of plate waste. It also provides targeted measures to reduce the associated CF of food waste in Chinese universities.

Irrespective of insights gained from previous studies on the impacts and adaptions associated with climate change; little consideration has been given to the effect of climate change on tourism on the Qinghai-Tibetan Plateau (QTP). Based on a conceptual framework of the impact of climate change on tourism in high-altitude regions; this paper reviews the literature pertaining to the effects of climate change on the natural characteristics of the QTP and it discusses the corresponding implications for tourism within the region. The findings show that the features of the QTP affected most by climate change comprise wetlands, glaciers, and the vegetation, wildlife, and climate resources. Accordingly, such effects could have considerable implications for related tourism activities. Climate change poses both challenges and opportunities for tourism development on the QTP. The information presented in this paper offers insight for tourism management on the QTP. Comprehensive measures involving all stakeholders should be taken to promote the sustainable development of tourism on the QTP, and to both mitigate the threats and exploit the opportunities related to climate change.
