Coupling Process-Based Crop Model and Extreme Climate Indicators with Machine Learning Can Improve the Predictions and Reduce Uncertainties of Global Soybean Yields

Abstract: Soybean is one of the most important agricultural commodities in the world, thus making it important for global food security. However, widely used process-based crop models, such as the GIS-based Environmental Policy Integrated Climate (GEPIC) model, tend to underestimate the impacts of extreme climate events on soybean, which brings large uncertainties. This study proposed an approach of hybrid models to constrain such uncertainties by coupling the GEPIC model and extreme climate indicators using machine lea… Show more

“…The researchers have integrated various machine learning methods with crop modeling and analyzed complex meteorological factors to offer precise predictions. The intricate interaction among climate change, agricultural practices, and machine learning methodologies presents opportunities for novel approaches to address food security and agricultural sustainability issues [41], [42]. South Asia and India, in particular, need more research in agricultural forecasts.…”

“…An alternative method to integrate the process-based crop model and ML (random forest algorithm) was proposed by [37] to reduce uncertainties of global soybean yield prediction. They suggest that this integration of the GIS-based Environmental Policy Integrated Climate (GEPIC) process-based model and extreme climate indicators using ML reduced uncertainty by 28.45-41.83% for the future scenario of 2040-2099.…”

“…In addition, EPIC-IIASA is applicable for studying the effects of CO 2 on yields in Argentina, Brazil, and the USA [12]. Process-based models can be coupled with artificial intelligence for crop assessment, i.e., machine learning links GEPIC to assess the effects of climate change on soybean in Argentina, Brazil, China, and the USA [13], and the application of artificial neural networks for the yield estimation in Maryland, USA [14]. The models are different from each other but geographically dependent, and thus their simulation performance levels are various.…”
