“…In this study, it was considered as 1 t of rice grain at the commercial moisture (86% of dry matter). The choice of the FU is in agreement with previous studies on rice in Italy (Fusi et al, 2014;Bacenetti et al, 2016a;Bacenetti et al, 2016b), Iran (Khoshnevisan et al, 2014), USA (Brodt et al, 2014, Fertitta-Roberts et al, 2019, Korea (Jeong et al, 2018), Japan (Hokazono and Hayashi, 2012), Thailand (Thanawong et al, 2014), andBrazil (Coltro et al, 2017), thus allowing a direct acomparison of results.…”

“…Therefore, reduction of field methane emissions would be an effective strategy for reducing CF; there are a number of appropriate farming practices that can serve this purpose. For example, Fertitta-Roberts et al (2019) reported that noncontinuous flooding can reduce methane emissions by 44%; Liu et al (2020d) found that N fertilizer deep placement can reduce methane on-field emission by 36–39%; Jiang et al (2019) reported that optimizing the amount of N fertilizer can reduce GHG emissions. Additionally, synthetic fertilizer was the principal component of GHG emission from agricultural inputs ( Table 5 and Figure 3 ), similar with the results reported by Chen et al (2020) and Xue et al (2016) ; in addition, indirect GHG emission from electricity accounts for up to 35.37% in DR system mainly because DR system needs a lot of electric power for pumping irrigation.…”

Shifting Rice Cropping Systems Mitigates Ecological Footprints and Enhances Grain Yield in Central China

Intensive cereal production has brought about increasingly serious environmental threats, including global warming, environmental acidification, and water shortage. As an important grain producer in the world, the rice cultivation system in central China has undergone excessive changes in the past few decades. However, few articles focused on the environmental impacts of these shifts from the perspective of ecological footprints. In this study, a 2-year field trial was carried out in Hubei province, China, to gain insight into carbon footprint (CF), nitrogen footprint (NF), and water footprint (WF) performance. The three treatments were, namely, double-rice system (DR), ratoon rice system (RR), and rice-wheat system (RW). Results demonstrated that RR significantly increased the grain yield by 10.22–15.09% compared with DR, while there was no significant difference in the grain yield between RW and DR in 2018–2019. All of the calculation results by three footprint approaches followed the order: RR < RW < DR; meanwhile, RR was always significantly lower than DR. Methane and NH3 field emissions were the hotspots of CF and NF, respectively. Blue WF accounts for 40.90–42.71% of DR, which was significantly higher than that of RR and RW, primarily because DR needs a lot of irrigation water in both seasons. The gray WF of RW was higher than those of DR and RR, mainly due to the higher application rate of N fertilizer. In conclusion, RR possesses the characteristics of low agricultural inputs and high grain yield and can reduce CF, NF, and WF, considering the future conditions of rural societal developments and rapid demographic changes; we highlighted that the RR could be a cleaner and sustainable approach to grain production.

“…Often, life cycle assessments can help deliver that message in a more holistic manner, grounding solutions within a quantifiable framework. Fortunately, new developments in life cycle assessments can improve representations of soil carbon storage [ 87 , 88 ], forest carbon cycling [ 89 ], and sustainable rice production practices [ 90 ]. Moreover, engineers can work with designers to develop and improve management tools to better convey best options and alternatives, with clear depictions of uncertainty, risk, cost, and benefit along a variety of decision metrics.…”

Nature-based Climate Solutions are landscape stewardship techniques to reduce greenhouse gas emissions and increase soil or biomass carbon sequestration. These mitigation approaches to climate change present an opportunity to supplement energy sector decarbonization and provide co-benefits in terms of ecosystem services and landscape productivity. The biological engineering profession must be involved in the research and implementation of these solutions—developing new tools to aid in decision-making, methods to optimize across different objectives, and new messaging frameworks to assist in prioritizing among different options. Furthermore, the biological engineering curriculum should be redesigned to reflect the needs of carbon-based landscape management. While doing so, the biological engineering community has an opportunity to embed justice, equity, diversity, and inclusion within both the classroom and the profession. Together these transformations will enhance our capacity to use sustainable landscape management as an active tool to mitigate the risks of climate change.
