Understanding the influence of COVID-19 on China's agricultural economy and the Chinese government's emergency measures to ease the economic impacts of viral spread can offer urgently-needed lessons while this virus continues to spread across the globe. Thus, this study collected over 750,000 words upon the topic of COVID-19 and agriculture from the largest two media channels in China: WeChat and Sina Weibo, and employed web crawler technology and text mining method to explore the influence of COVID-19 on agricultural economy and mitigation measures in China. The results show that: (1) the impact of COVID-19 on China's agricultural economy at the very first phase is mainly reflected in eight aspects as crop production, agricultural products supply, livestock production, farmers' income and employment, economic crop development, agricultural products sales model, leisure agriculture development, and agricultural products trade. (2) The government's immediate countermeasures include resuming agricultural production and farmers' work, providing financial support, stabilizing agricultural production and products supply, promoting agricultural products sale, providing subsidies, providing agricultural technology guidance and field management, and providing assistance to poor farmers to reduce poverty. (3) The order of government's immediate countermeasures is not all in line with the order of impact aspects, which indicates that more-tailored policies should be implemented to mitigate the strikes of COVID-19 on China's agricultural economy in the future.

Abstract:A high demand for seafood leads to overfishing, harms the long-term health of seafood stocks, and threatens environmental sustainability in oceans. Sustainability certification is one of the major sustainability movements and is known as eco-labeling. For instance, in the tuna industry, leading tuna brands have committed to protecting sea turtles by allowing the tracing of the source of their tuna "from catch to can." This paper relies on an Internet survey on consumers from Kentucky conducted in July 2010. The survey investigates household-level tuna steak (sashimi grade) consumption and examines consumer preferences for eco-labeling ("Certified Turtle Safe" (CTS) in this study) while mimicking individuals' seafood procurement processes. A random parameter logit model is utilized, and willingness-to-pay measures are calculated based on model estimation results. It was found that respondents on average preferred turtle-safe-labeled tuna steak and were likely to pay more for it; however, they were less likely to purchase wild-caught species, and insignificant results were found for pre-frozen. Moreover, significant heterogeneities were found across individuals regarding tuna steak purchases. The findings indicate evidence of public support for environmental friendliness, particularly with regard to eco-labeling.

Residential lawns provide diverse benefits, including social (e.g., enhancing humans' physical and psychological well-being), economic (e.g., increasing real estate values), and environmental (e.g., supporting local ecosystems) benefits. However, improper lawn fertilizer applications can cause adverse environmental consequences, such as excessive chemical runoff into adjoining watersheds leading to water contamination. Currently, the importance of eco-friendly fertilizers to homeowners has not been assessed. This study uses a discrete choice experiment to test whether eco-friendly fertilizer attributes influence homeowners' preferences for sustainable landscape management. The findings show that eco-friendly fertilizer attributes positively influence homeowners' preferences and willingness to pay, supporting the premise that the promotion of eco-friendly fertilizer features could improve local ecosystems through increased adaptation. Furthermore, this study tests whether certain fertilizer attributes influence homeowners' preferences in states with and without fertilizer restrictions. Since the regulatory environment affects homeowners' preferences for sustainable landscaping, this study compares the results between regulated and unregulated states. The findings reveal that homeowners are more likely to use and are willing to pay higher premiums for sustainable fertilizers in states with residential fertilization regulations. This suggests that with strict fertilizer ordinances, homeowners are more geared toward eco-friendly landscaping options and that related educational programs should be made available.Les pelouses résidentielles offrent divers avantages, incluant les avantages sociaux (comme la valorisation du bien-être physique et psychologique humain),économiques (comme la valeur immobilière), et environnementaux (comme l'appui desécosystèmes locaux). La mauvaise application des fertilisants a parfois des conséquences environnementales négatives comme le ruissellement chimique excessif dans les bassins hydrographiques attenants menantà la contamination des sources d'eau. En raison de l'importance des fertilisants respectueux de l'environnement pour la protection de ce dernier, cetté etude emploie une expérience avec choix discrets pourévaluer si les attributsécologiques des fertilisants influencent les préférences des consommateurs et leur volonté de payer pour une gestion durable de l'aménagement. Les résultats indiquent que les attributsécologiques des fertilisants influencent
