“…China is the world's largest emitter of NH 3 (9)(10)(11)(12)(13) Tg N year −1 in the 2010s), with over 80% contributed by agriculture 8,9 . Low fertilizer nitrogen (N) use efficiency (NUE) and poor animal waste management have resulted in enormous NH 3 emissions in China 8,10 .…”

Mitigating agricultural ammonia (NH 3) emissions in China is urgently needed to avoid further damage to human and ecosystem health. Effective and feasible mitigation strategies hinge on integrated knowledge of the mitigation potential of NH 3 emissions and the associated economic costs and societal benefits. Here we present a comprehensive analysis of marginal abatement costs and societal benefits for NH 3 mitigation in China. The technical mitigation potential of agricultural NH 3 emissions is 38-67% (4.0-7.1 Tg N) with implementation costs estimated at US$ 6-11 billion. These costs are much lower than estimates of the overall societal benefits at US$ 18-42 billion. Avoiding unnecessary fertilizer use and protein-rich animal feed could provide 30% of this mitigation potential without additional abatement costs or decreases in agricultural productivity. Optimizing human diets with less animalderived products offers further potential for NH 3 reduction of 12% by 2050.

“…The gross output value of livestock production in 2018 in China is RMB 28,697 billion ($4159 billion), which is 137 times more than the value in 1978. Currently, China is the world's largest producer of livestock products [2]. The continued increase in livestock production has generated a large amount of manure.…”

“…Most existing studies have treated farmers' adoption of SMTTs as separate decisions, focusing on the adoption of only one or two isolated types of SMTTs independently, such as returning to the field [2,9], producing biogas [10,11], composting [12], sale [7], and arbitrary discard [13]. Limited attention has been given to the adoption of multiple types of SMTTs.…”

Adoption of Multiple Sustainable Manure Treatment Technologies by Pig Farmers in Rural China: A Case Study of Poyang Lake Region

The adoption of sustainable manure treatment technologies (SMTTs) in livestock production helps to reduce agricultural contamination. As such, understanding what determines farmers’ adoption of SMTTs is an essential prerequisite for the administrative handling of livestock pollution. Applying a multivariate probit model on a cross-sectional data set of 686 pig farmers in Poyang Lake Region in China, this study discovered that two key factors influencing farmers’ decisions to adopt multiple SMTTs are off-farm labor and environmental awareness. In other words, households with a higher share of off-farm labor are less likely to adopt SMTTs. Farmers with higher environmental awareness are more likely to adopt SMTTs. The results also revealed that because of the inappropriateness of government subsidy and insufficient technical training, the impact of Chinese government subsidy on the adoption of biogas technology is negligible, but the subsidy on composting greatly helps to promote the adoption of composting technology. We also found a substitution effect and complementary effects between different SMTTs. These findings can improve policymakers’ understanding of farmers’ joint adoption decisions. It also helps policymakers to optimize subsidy strategies to encourage farmers’ adoption of SMTTs in rural China.

“…On the one hand, the progressive substitution of mineral fertilizers for organic fertilizers can improve soil fertility and recover poor soils (Sanz-Cobena et al, 2017b;Zhang et al, 2019). On the other hand, practices such as no-till of lands significantly increased yields and improved soil quality, also shifting the microbial community and activity associated with an increase in organic matter, carbon, nitrogen and phosphorus cycling (Mbuthia et al, 2015).…”

“…Replacing a part of chemical N fertilizer is an excellent strategy to mitigate the negative impacts (Jat et al, 2019). However, there are still several limitations in the economic and source of alternative fertilizers (Zhang et al, 2019). Evidently, chemical fertilization cannot and should not be totally removed from crop management tasks, instead, better fertilization programs have been carefully elaborated since the efficiency of fertilization is a critical issue to reduce environmental impacts of agricultural activities and ensure food production (Recio et al, 2018;Zhang et al, 2015).…”
