“…Qin et al [13] studied midseason drainage and organic manure incorporation in Southeast China and found that the GHGI varied from 0.24 to 0.74 kg·CO 2 eq·kg −1 yield, which was lower than in this study. In Thailand, the study of Yodkhum and Sampattagul [60], who applied a life cycle assessment concept and carbon footprint to determine GHG emissions of rice production in Thailand, reported that in northeast Thailand, GHG emissions of KDML 105 of NongKhai was 2.39 kg·CO 2 eq·kg −1 yield, which was higher than in this study. Arunrat et al [30] estimated GHG emissions based on the concept of the life cycle assessment of the greenhouse gas emissions (LCA-GHG) of products in Phichit province of Thailand.…”

Land management practices for rice productivity and carbon storage have been a key focus of research leading to opportunities for substantial greenhouse gas (GHG) mitigation. The effects of land management practices on global warming potential (GWP) and greenhouse gas intensity (GHGI) from rice production within the farm gate were investigated. For the 13 study sites, soil samples were collected by the Land Development Department in 2004. In 2014, at these same sites, soil samples were collected again to estimate the soil organic carbon sequestration rate (SOCSR) from 2004 to 2014. Surveys were conducted at each sampling site to record the rice yield and management practices. The carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous oxide (N 2 O) emissions, Net GWP, and GHGI associated with the management practices were calculated. Mean rice yield and SOCSR were 3307 kg·ha −1 ·year −1 and 1173 kg·C·ha −1 ·year −1 , respectively. The net GWP varied across sites, from 819 to 5170 kg·CO 2 eq·ha −1 ·year −1 , with an average value of 3090 kg·CO 2 eq·ha −1 ·year −1 . GHGI ranged from 0.31 to 1.68 kg·CO 2 eq·kg −1 yield, with an average value of 0.97 kg·CO 2 eq·kg −1 yield. Our findings revealed that the amount of potassium (potash, K 2 O) fertilizer application rate is the most significant factor explaining rice yield and SOCSR. The burning of rice residues in the field was the main factor determining GHGI in this area. An effective way to reduce GHG emissions and contribute to sustainable rice production for food security with low GHGI and high productivity is avoiding the burning of rice residues.

“…By using organic fertilizers such as green manure seeds, farmyard manure, compost and biofermented juice derived from fermentation processes, the GHG emissions were found to be much lower (0.58 kg CO 2 per kg of paddy rice) compared to rice production with chemical fertilizer usage. The rice production practices can also be further adjusted by reducing the flooding period and applying alternative wetting and drying techniques to conserve water and mitigate methane emissions [74].

The management of solid waste presents a challenge for developing countries as thegeneration of waste is increasing at a rapid and alarming rate. Much awareness towards thesustainability and technological advances for solid waste management has been implemented toreduce the generation of unnecessary waste. The recycling of this waste is being applied to producevaluable organic matter, which can be used as fertilizers or amendments to improve the soil structure.This review studies the sustainable transformation of various types of biomass waste such as animalmanure, sewage sludge, municipal solid waste, and food waste, into organic fertilizers and theirimpact on waste minimization and agricultural enhancement. The side effects of these organicfertilizers towards the soil are evaluated as the characteristics of these fertilizers will differ dependingon the types of waste used, in addition to the varying chemical composition of the organic fertilizers.This work will provide an insight to the potential management of biomass waste to be produced intoorganic fertilizer and the advantages of substituting chemical fertilizer with organic fertilizer derivedfrom the biomass waste.

“…Moreover, the production of N fertilizer is also a large GHG emission source [56]. Yodkhum et al [57] using the life cycle assessment methods to compare the organic and conventional rice production, and the comparative results showed that the GHG emissions of organic paddy rice were considerably lower than that of conventional rice production by accounting all GHG emissions including upstream and downstream ones. Otherwise, the carbon trade price was US $17 ton −1 of CO 2 equivalent [58] and the carbon costs were 49.3 and 45.2 US $ ha −1 for the ER and CK system, respectively.…”

The sustainability of intensification of rice production is a prime concern for China. Application of organic amendments, changes in crop rotation system, ducklings' introduction, and construction of vegetated drainage ditches are some of the original management strategies to mitigate environmental pollution from paddy fields. Although these practices affect the rice culturing system through different mechanisms, there is limited investigation on their effectiveness on nutrient pollution alleviation. Therefore, a field study was carried out with the assessment of soil physico-chemical properties, greenhouse gas emissions, nitrogen removal efficiency, grain yield, and economic benefits by comparing the eco-rice culturing system (ER) to the local single rice cultivation system (CK). Results showed that the ER system can significantly improve soil fertility by increasing the pH in acidic soil, organic matter, total nitrogen (TN), and available potassium (K) content by 5.2%, 25.7%, 19.1%, and 19.4% in relation to CK, respectively. Meanwhile, about 10% of the total fertilizer N was removed from the harvesting of the plant species (Myriophyllum elatinoides and Pennisetum purpureum) in the vegetated drainage ditches. However, the ER system decreased the plant height (1.1%) and the number of tillers (9.6%), resulting in a reduction of the total grain yield (6.0%). Moreover, compared with the CK system, the ER system increased CH 4 cumulative emission, global warming potential (GWP), and greenhouse gas intensity (GHGI) by 11.1%, 8.1%, and 14.3%, respectively, and decreased N 2 O by 27.2%, but not statistical significantly (p < 0.05). Even so, by taking the costs of farm operations and carbon costs of greenhouse gas emissions, the net economic benefits by applying the ER system were higher relative to the CK system. Thus, our study provides further understanding of the technology which has the potential to transform sustainable rice production to a more profitable, income generating, and environmentally friendly industry in China.
