“…et al, 2017). The higher SOC accretion rate by W-W vs. P g /O-W likely resulted from slightly greater biomass-C inputs under W-W than P g /O-W and lower quality (high C:N ratio) of WeW residues (O'Dea et al, 2015;Duval et al, 2016). This response was consistent with reports by Kaiser and Guggenberger (2000) and Kramer et al (2012) that recalcitrant, aromatic DOM is the greatest contributor for long-term SOC storage.…”

“…In Paraguay, indigenous people grow grey-seeded mucuna leaves which are excellent dead cover that protects soil from erosion and weeds (FAO 2011a). Cover crops are sustainable farming tool that increase SOM and improve soil water dynamics (Steele et al 2012;Poeplau and Don 2015;Basche et al 2016;Duval et al 2016). Basche et al (2016) found that long-term use of a winter rye cover crop enhanced soil water dynamics such as water content and soil water storage in a maize-soybean cropping system.…”

Sustainable food production is one of the major challenges of the twenty-first century in the era of global environmental problems such as climate change, increasing population and natural resource degradation including soil degradation and biodiversity loss. Climate change is among the greatest threats to agricultural systems. Green Revolution though multiplied agricultural production several folds but at the huge environmental cost including climate change. It jeopardized the ecological integrity of agroecosystems by intensive use of fossil fuels, natural resources, agrochemicals and machinery. Moreover, it threatened the age-old traditional agricultural practices. Agriculture is one of the largest sectors that sustain livelihood to maximum number of people and contribute to climate change. Therefore, a climate-smart approach to sustainable food production is the need of hour. Traditional agriculture is getting increased attention worldwide in context of sustainable food production in changing climate. The present article advocates traditional agriculture as a climate-smart approach for the sustainable food production and also deliberates the correlation between climate change and agriculture.

“…Some studies even suggested negative effects of CSA management practices on SOC (e.g., Liang, Zhang, Fang, Yang, & Drury, 2007;Tian, Kang, Kolawole, Idinoba, & Salako, 2005). Some recent studies reported that a combination of cover crops and conservation tillage could significantly increase SOC compared to a single management practice (Ashworth, Allen, Wight, Saxton, & Tyler, 2014;Blanco-Canqui, Holman, Schlegel, Tatarko, & Shaver, 2013;Duval, Galantini, Capurro, & Martinez, 2016;Higashi et al, 2014). Some recent studies reported that a combination of cover crops and conservation tillage could significantly increase SOC compared to a single management practice (Ashworth, Allen, Wight, Saxton, & Tyler, 2014;Blanco-Canqui, Holman, Schlegel, Tatarko, & Shaver, 2013;Duval, Galantini, Capurro, & Martinez, 2016;Higashi et al, 2014).…”

Climate‐smart agriculture (CSA) management practices (e.g., conservation tillage, cover crops, and biochar applications) have been widely adopted to enhance soil organic carbon (SOC) sequestration and to reduce greenhouse gas emissions while ensuring crop productivity. However, current measurements regarding the influences of CSA management practices on SOC sequestration diverge widely, making it difficult to derive conclusions about individual and combined CSA management effects and bringing large uncertainties in quantifying the potential of the agricultural sector to mitigate climate change. We conducted a meta‐analysis of 3,049 paired measurements from 417 peer‐reviewed articles to examine the effects of three common CSA management practices on SOC sequestration as well as the environmental controlling factors. We found that, on average, biochar applications represented the most effective approach for increasing SOC content (39%), followed by cover crops (6%) and conservation tillage (5%). Further analysis suggested that the effects of CSA management practices were more pronounced in areas with relatively warmer climates or lower nitrogen fertilizer inputs. Our meta‐analysis demonstrated that, through adopting CSA practices, cropland could be an improved carbon sink. We also highlight the importance of considering local environmental factors (e.g., climate and soil conditions and their combination with other management practices) in identifying appropriate CSA practices for mitigating greenhouse gas emissions while ensuring crop productivity.
