“…Energy production, therefore, is based on the use of fossil fuels and is responsible for the direct emission of greenhouse gasses such as CO 2 and N 2 O, which inevitably affect GWP, as well as particulate matter. These results are also confirmed in ozone formation-human health, ozone formation-terrestrial ecosystems and fine particulate matter formation, where irrigation impacts on average about 80% (1.28 × 10 1 kg NO X eq out on 1.60 × 10 1 kg for OFHH, 1.29 × 10 1 kg NO X out on 1.62 × 10 1 for OFTE and 9.99 × 10 0 kg PM 2.5 eq out on 1.20 × 10 1 kg for FPMP), in line with the findings of Escobar et al (2022), where energy consumption for irrigation turns out to be the primary source of OFHH and OFTE, causing 75% of these impacts. But these results are also confirmed in the fossil resource scarcity (FRS), where irrigation impacts about 74% (1.78 × 10 3 kg oil eq out on 2.42 × 10 3 kg) and in agreement with Xu et al (2022), who show that energy consumption under conventional rice production in China had the largest impact (35-38%) on FRS.…”

“…The choice of these system boundaries is mainly related to the fact that they are considered in most LCA studies in which the impacts of rice production are analyzed. For example, Escobar et al (2022) who in their study considered all the processes involved in paddy rice production in Senegal (fertilizer and herbicide production, as well as production of diesel to operate machinery); Yu et al (2022), Shen et al (2021), andChen et al (2021) who assess the environmental impacts of some rice production in China, considering rice planting, irrigation, weeding, nutrition, and field operations, including the production processes of various inputs (fuels, pesticides, and various fertilizers) until the final product is harvested; or Rezaei et al (2021), Houshyar et al (2019), and Masuda (2019, who quantify the impacts of rice production in Iran (Rezaei et al 2021 andHoushyar et al 2019) and Japan (Masuda 2019), starting from the production of the inputs needed for production, to the harvesting of the finished product.…”

“…Confirming this, it also appears to be the most commonly used methodology in LCA studies of rice production. In fact, from a Scopus literature review, in the last 5 years, about eight authors(Xu et al 2022;Escobar et al 2022;Rezaei et al 2021;Shew et al 2019;Habibi et al 2019; Harun et al 2021;Yodkhum et al 2018;Jimmy et al 2017) have used this methodology. Therefore, as a matter of completeness and greater detail of environmental impacts, and to make the results of our study comparable with other literature studies, we chose to use the ReCiPe 2016 Midpoint (H) methodology.…”

Purpose The study’s objective is to assess the environmental performance of rice production in Northern Italy, in particular in Piedmont, the first Italian and European district for the rice-growing area, and thus identify the most critical hotspots and agricultural processes. In particular, as a case study, a farm located in Vercelli (VC) has been chosen. Subsequently, the study results were compared with other different cultivation practices to evaluate the most sustainable choice. Methods The application of the LCA has been performed, highlighting the phases of rice production that have the most significant impact. Then, uncertainty and sensitivity analyses have been made to estimate the robustness of the results and assess the influence of changing some input variables on emission reduction. Finally, multivariate statistical, specifically a principal component analysis (PCA), was conducted to aid the interpretation of the output dataset of this case study. LCA, uncertainty analysis, and sensitivity analysis were performed with SimaPro 9.2.0, using ReCiPe 2016 Midpoint (H) methodology, and PCA with R software. Results and discussions The hotspot with the highest environmental load is irrigation, which compared to the other phases impacts more in 15 out of 18 categories, including 12 with impacts greater than + 75%. This is because irrigation causes direct impacts, related to the methanogenesis in rice fields, but also indirect impacts related mainly to the production of the energy mix required to move the large masses of irrigation water. Therefore, different water management systems were compared and results show that the irrigation systems based on intermittent paddy submergence (DSI) could result in − 40% lower impacts, resulting to be the preferable technique over the other irrigation systems analyzed, including the traditional one used in this study. Conclusions In order to reduce the environmental impacts related to the irrigation process, a water management system characterized by intermittent flooding of the paddy field (DSI) could be used as it reduces the environmental impacts the most (− 40%), while the least suitable system is one characterized by continuous flooding without drought periods, as it causes the highest impacts.

“…The assessment of environmental risks and health damages of rice production can be done by life cycle assessment (LCA) [2]. The LCA technique considers all input and output sources of the whole production system and can be therefore used to analyze the probable impact of agricultural production on the environment from raw material extraction to final product production and disposal [23,24].…”

Environmental Life Cycle Assessment in Organic and Conventional Rice Farming Systems: Using a Cradle to Farm Gate Approach

et al. 2022

View full text Add to dashboard Cite

The rising demand for agricultural products and expanding public awareness of environmental friendliness have led to the adoption of the organic farming system rather than the conventional one. The life cycle assessment (LCA) concept is a frequently used method to examine the environmental impacts of any activity across its entire life cycle. This research is the first use of LCA for the impacts of vermicompost and cattle manure as organic fertilizers in rice farming. The main goal of this study was to compare the environmental impacts of conventional and organic rice farming. This paper uses midpoint attributional LCA to analyze environmental damages during rice production. The four primary harm categories used in this strategy to categorize the environmental effects were: (1) climate change, (2) human health, (3) ecosystem quality, and (4) resources. The inventory data for the agricultural stage were obtained through farmer interviews. The system boundaries were set to cradle to farm gate, and 1 ton of final product (dry matter) was used as the functional unit. The results show that in all main damage categories, except for particulate matter formation, stratospheric ozone depletion, mineral resource scarcity, and freshwater eutrophication, conventional rice production has higher environmental impacts than organic rice production. Overall, organic rice production is more effective in diminishing the negative environmental effects of farming compared to conventional rice production.
