Watershed eco-compensation (WEC) is considered a significant environmental policy instrument for watershed ecological protection and management. However, in the legislation and practice of eco-compensation in China, the development of the WEC mechanism is still in the initial stages. In this paper, the institutional opportunities and challenges of WEC are analyzed from the existing policies, laws, and economical instruments. Theoretically, WEC in China has seen a combination of punitive-based “Watershed Ecological Damage Compensation (WEDC)” and incentive-based “Watershed Ecological Protective Compensation (WEPC)”. Through a comparative analysis of domestic and foreign watershed compensation practices, the results demonstrate that most of China’s WEC projects have an insufficient legal basis, a single compensatory subject, insufficient compensation funds, and an imperfect market-oriented compensation mechanism. To improve watershed eco-compensation in China, it is recommended to strengthen legislation, select diversified eco-compensation approaches, and establish a market-based and systematic eco-compensation mechanism for watersheds.

The changing climate represents a large challenge for farmers, and adaptation responses are necessary to minimize impacts. Mixed approaches, which involve the analysis of meteorological data, web-based surveys, and face-to-face interviews, explore producers’ barriers and pressing needs to enhance climate resilience based on the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) approach in semi-arid north-western China. According to the main categories of farming activity, 85 crop farmers, 68 animal farmers, and 81 agro-tourism operators were interviewed. We found that most of the producers perceived climate impacts, and they encountered multiple adaptation obstacles, of which institutional and normative obstacles were more serious, such as farmers unable to obtain resources or government incentives, lacked scientific, and efficient coping measures. The survey also observed that crop farmers had a pressing need for agricultural subsidies, while animal farmers and agro-tourism operators had a strong enabler for animal housing infrastructure and credit facilities, respectively. Given the heterogeneity of the context and climate change experience of different categories of farmers, it is necessary to formulate flexible adaptation strategies and adjust them according to specific climate stress and farming conditions. To achieve the Sustainable Development Goals and implement the 2015 Paris Agreement, policymakers should plan and introduce appropriate adaptation strategies to minimize the adverse effects of climate change such as improving irrigation and weather forecasting system through technological advancement, cost reduction of farm inputs, ensuring availability of information, providing agricultural subsidies to the farmers, and increasing the access to agricultural markets.

Selenium (Se) deficiency in humans could be improved by biofortification of food with selenium, 1-Methylcyclopropene (1-MCP) treatment is beneficial for the non-sulfur storage of fresh fruit. This study investigated fruit quality of table grape (Hutai No.8) with foliar Se fertilizer at maturity, and fruit quality changes of table grape during shelf life stages that caused by postharvest 1-MCP treatment in 2016 and 2017. The results showed that foliar Se fertilizer application significantly increased Se content in grape berries at maturity, and the raised rate were 43.09% and 33.24% compared to that of control in 2016 and 2017 respectively, meanwhile it increased the nutritional components in grape berries, including soluble proteins, soluble sugars, Vitamin C, total soluble solids, proanthocyanidin content and so on, and decreased the titratable acidity content. During shelf life stages, 1-MCP application decreased the decay number of grapes, and SE + 1-MCP treatment had the most excellent fruit quality among all treatments in two consecutive vintages. In conclusion, Se fertilizer application could increase Se content in grape berries, also improved the fruit nutritional and health care values at maturity. 1-MCP application could delay the process of ripening and senescence for Se-enriched grape and maintaining the postharvest quality of table grape during shelf life stages, it allows us to market the fruit at a more advanced ripening stage without quality loss.

This paper takes the implementation of the River Chief System (RCS) as a case study representing government-led environmental governance policies. Based on the sample of 11,654 observations of Chinese A-share-listed companies spanning the years 2009 to 2021, it empirically examines the effect of the RCS on corporate Environmental, Social, and Governance (ESG) performance and the macro- and micro-mechanisms utilizing a staggered Difference-in-Differences (DID) model, controlling for companies’ financial and organizational structure characteristic variables, cities’ economic characteristic variables, and firm-year two-way fixed effects. The results indicate that the implementation of the RCS significantly enhances corporate ESG performance, a conclusion supported by various robustness checks such as the parallel trend test and placebo test. Further investigation reveals that implementing the RCS, at the micro level, boosts corporate green technology innovation, increases environmental protection investment, and, at the macro level, heightens public environmental attention, thus improving corporate ESG performance. Heterogeneity analysis finds that the RCS has a more pronounced impact on enhancing ESG performance for enterprises in central and western regions of China, state-owned enterprises, enterprises with political connections, and enterprises in mature and declining stages. These research findings of this paper provide valuable insights for local governments seeking to enhance the RCS, enrich environmental governance frameworks, and facilitate corporate green transformation.

Agricultural E-commerce alters farmers’ production and marketing decisions, thereby shaping land-use intensity and livelihood stability. In the context of rapid digital transformation, enhancing farmers’ livelihood resilience is critical to sustainable rural development and resilience to socio-economic and environmental shocks. Using survey data from 542 rural communities in China, this study examines the relationship between agricultural E-commerce participation and farmers’ livelihood resilience across its multidimensional components. The empirical results show that participation in agricultural E-commerce is positively associated with farmers’ overall livelihood resilience, with notable positive associations with buffering capacity, learning capacity, and self-organization capacity. Among these, learning capacity exhibits the strongest association, followed by buffering capacity and self-organization capacity. Farmers’ digital capability positively moderates the relationship between E-commerce participation and livelihood resilience by facilitating access to and effective use of digital information, thereby lowering information costs and contributing to returns from online market participation. Heterogeneity analysis further indicates that the positive association between agricultural E-commerce participation and livelihood resilience is stronger among cooperative members, households with adequate production capital, non-agricultural households, and families with sufficient labor resources. By identifying the role of agricultural E-commerce in building livelihood resilience, this study contributes to the empirical understanding of how digital engagement may support inclusive and sustainable rural development under similar institutional conditions.
