Biomass burning contributes considerably to black carbon (BC) emissions in South Asia, but such emissions have not been linked with the Green Revolution (GR) which has enabled substantial crop production growth in South Asian countries, India in particular. Here, we use an Earth system model to quantify climate change through the direct radiative forcing (DRF) by agriculture-emitted BC associated with the GR in India. We show that the BC DRF in India has increased significantly since the GR, especially during the post-GR period. The estimated BC DRF in India rose from +0.197 W/m² in 1961 to +0.805 W/m² in 2011; this represents a fourfold increase in DRF since the onset of the GR. The contribution of BC DRF by India's intensive agriculture to the global BC forcing also increased from 2.6% to 4.4% during the GR. Our results reveal that increasing BC emissions associated with the GR raises the importance of emission mitigation from agriculture source.

与印度绿色革命相关的农业排放黑碳的直接辐射强迫影响

生物质燃烧对南亚的黑碳 (BC) 排放有很大贡献，但此类排放与绿色革命 (GR) 无关，后者使南亚国家，尤其是印度的作物产量大幅增长。在这里，我们使用地球系统模型通过与印度 GR 相关的农业排放 BC 的直接辐射强迫 (DRF) 来量化气候变化。我们表明，自 GR 以来，印度的 BC DRF 显着增加，尤其是在后 GR 时期。所估计的BC DRF在印度从0.197 W /米玫瑰²在1961至0.805瓦/米²在2011年; 这代表自 GR 开始以来 DRF 增加了四倍。在 GR 期间，印度集约化农业对全球 BC 强迫的 BC DRF 贡献也从 2.6% 增加到 4.4%。我们的结果表明，与 GR 相关的 BC 排放量的增加提高了农业源排放减缓的重要性。
