Résumé : | Context Organic farming is a fast-growing system considered a holistic approach that benefits the environment. However, previous studies have reported varying results on its productivity when compared to conventional farming systems. Moreover, the effect of climatic conditions on the yield gap between organic and conventional methods has not been extensively studied. Objectives Considering the influence of temperature and precipitation on soil microbial activity that drives the decomposition of organic matter and supports the mineralization of organic matter for plants, we hypothesized that the yield gap between organic and conventional farming systems is affected by climatic conditions; that is, it should be higher in locations with warmer climates that those in colder climates. Methods Yield data were collected from 105 studies that compared organic and conventional farming; 786 pairwise observations were extracted mainly from previous meta-analyses and individual studies. Using meta-analysis in R software, we examined the yield ratio between the two farming systems in different climate types (boreal, warm temperate, arid, and equatorial) and sub-types, and further investigated other influencing factors such as crop type, study location by region, and soil pH and texture. Results and conclusions The yield of organic farming was 18.4% (RR = 0.83; 95% confidence interval of 0.77 to 0.89; p = |
