“…This is consistent with results reported by Joseph et al, whose summary of meta-analyses shows that biochar application can reduce non-CO 2 GHG emissions in soils by 12–50% . Much like biochar, soil temperature and moisture are significant factors on net CH 4 emissions for conservation tillage systems . Previous studies have demonstrated CH 4 emission reductions in no-till farming of rice due to increased oxidation activity, ,, but Hao et al noted increased emissions due to the continuously flooded conditions .…”

“…Ogle et al found the impact of SOC from no-till practices to be restricted to topsoil (<20 cm), with full tillage showing higher SOC stocks beyond the surface (>20 cm), especially for soils in tropical and warm temperate climates . The authors of both meta-analyses suggest that the GHG mitigation of no-till practices is limited. , Maucieri et al reported an increase in CO 2 , N 2 O, and CH 4 emissions from no-till practices due to soil changes facilitated by the decomposition of residues . The level of soil disturbance (or redistribution of organic carbon) and decomposition rates within the soil profile can influence sequestration potential .…”

The worldwide emphasis on reducing greenhouse gas (GHG) emissions has increased focus on the potential to mitigate emissions through climate-smart agricultural practices, including regenerative, digital, and controlled environment farming systems. The effectiveness of these solutions largely depends on their ability to address environmental concerns, generate economic returns, and meet supply chain needs. In this Review, we summarize the state of knowledge on the GHG impacts and profitability of these three existing and emerging farming systems. Although we find potential for CO2 mitigation in all three approaches (depending on site-specific and climatic factors), we point to the greater level of research covering the efficacy of regenerative and digital agriculture in tackling non-CO2 emissions (i.e., N2O and CH4), which account for the majority of agriculture’s GHG footprint. Despite this greater research coverage, we still find significant methodological and data limitations in accounting for the major GHG fluxes of these practices, especially the lifetime CH4 footprint of more nascent climate-smart regenerative agriculture practices. Across the approaches explored, uncertainties remain about the overall efficacy and persistence of mitigationparticularly with respect to the offsetting of soil carbon sequestration gains by N2O emissions and the lifecycle emissions of controlled environment agriculture systems compared to traditional systems. We find that the economic feasibility of these practices is also system-specific, although regenerative agriculture is generally the most accessible climate-smart approach. Robust incentives (including carbon credit considerations), investments, and policy changes would make these practices more financially accessible to farmers.

“…Ashraf et al, [96] studied the carbon emission estimation from rice and wheat cropping. Maucieri et al, [97] provided the meta-analysis on the crop residue management with different tillage systems to control the environmental pollution. The studies find out that the crop residue management in the field have a significant effect on both agriculture and environmental health.…”

Increasing demand of agricultural production for human, animal, and industrial requirements is responsible for the enhancement of agricultural and agro-industrial activities. Each step of such activities produces various types of agricultural waste that include crop residue, on-farm livestock and fisheries waste, forest waste, agro-industrial waste, etc. Currently, handling and managing agricultural waste is a challenging task worldwide, especially in the context of environmental pollution control and sustainable agriculture. Thus, efficient management in terms of reuse, recycling, and reduction of agricultural waste is needed not only for the sustainable agriculture but also for farmers’ profitability. Various type of farm machinery is available and are in use to collect the crop residue from the field or directly incorporate the residue into the soil. The incorporated crop residue not only increases the soil fertility but also decreases the greenhouse gases emission due to burning of the crop residue. The crop residue chopper can be a solution of residue management at farmer field level. This chapter provides a review on the crop residue collection handing and incorporation machinery performance and their advancement.

“…CO 2 emitted into the atmosphere through soil respiration is more than 11 times of that released by fossil fuel combustion (Peng et al, 2011). Over a half (50%–65%) of CH 4 emissions are from various anthropogenic activities, especially agricultural production, which can be reduced by scientific management of soil (Maucieri et al, 2021; Nazaries et al, 2013). Besides, about 60% of the annual global N 2 O emission comes from soil, which makes soil a significant source of N 2 O (Liu et al, 2008).…”

Exploring the responses of greenhouse gas (GHG) emissions to land use conversion or reversion is significant for taking effective land use measures to alleviate global warming. A global meta-analysis was conducted to analyze the responses of carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous oxide (N 2 O) emissions to land use conversion or reversion, and determine their temporal evolution, driving factors, and poten-
