Data and supplementary materials for: Climate Change Impacts on Soil Biogeochemical Processes in Irrigated Rice Systems: Greenhouse Gas Emissions and Adaptive Management Strategies

Description

This dataset supports a PRISMA 2020-aligned systematic narrative review examining how soil redox dynamics, microbial functional groups, agricultural management practices, and climate drivers interact to control methane (CH₄) and nitrous oxide (N₂O) emissions in irrigated rice systems. The review hypothesized that no single mitigation practice fully controls the CH₄–N₂O trade-off, and that integrating water management, soil amendments, and crop/nutrient strategies would be needed to achieve substantial net greenhouse gas reductions while sustaining yield. The dataset comprises the complete search and screening documentation (search strategy across Scopus, Web of Science, PubMed, and OpenAlex; PRISMA 2020 flow diagram; inclusion and exclusion criteria) that led to the selection of 82 peer-reviewed studies (2018–2025) from an initial pool of 5,993 records, and the data extracted from those studies (list of included studies with DOIs; four extraction tables summarizing reported effects of climate/CO₂, water management, soil amendments, and crop/nutrient management on CH₄ and N₂O emissions, yield, and global warming potential). Key findings from the synthesis include: alternate wetting and drying reduces CH₄ by approximately 50% with a comparatively small N₂O trade-off; iron-based amendments are among the few practices achieving simultaneous CH₄ and N₂O mitigation; and the stimulatory effect of elevated CO₂ on emissions reverses over decadal timescales. To interpret the extraction tables, each row reports the treatment effect relative to a stated control (e.g., continuous flooding) as extracted directly from the cited primary source; percentage changes are not independently re-derived. The included studies list can be cross-referenced with the extraction tables via the citation key (author + year) column.

Steps to reproduce

The dataset was compiled following the PRISMA 2020 protocol for systematic reviews. Database searches (Scopus, Web of Science, PubMed, OpenAlex) were conducted using five Boolean search blocks combining terms for greenhouse gases, rice cultivation, soil biogeochemistry, water management, and soil amendments (full strings in Search_Strategy.pdf). Duplicate removal was performed by DOI matching and normalized title comparison. Title, abstract, and full-text screening were performed independently by two authors against predefined inclusion/exclusion criteria (Inclusion_Exclusion_Criteria.pdf), with discrepancies resolved by discussion. A three-criterion relevance scoring system (thematic coverage, methodological rigor, geographic/topical representativeness; maximum 8 points) was applied to the 403 eligible records to select the 82 highest-scoring studies for full data extraction. Data extraction from each included study (reported effects on CH₄, N₂O, yield, and global warming potential) was performed manually and organized into the four extraction tables provided. No laboratory instruments, reagents, or specialized software were used; reference organization and data compilation were carried out using standard spreadsheet software (Microsoft Excel).
