Land-atmosphere feedbacks contribute to crop failure in global rainfed breadbaskets

H. Li, J. Keune, et al.

This research reveals alarming insights into how land-atmosphere feedbacks significantly impact crop yields in the world's largest rainfed breadbaskets. Discover how local and upwind conditions can lead to a staggering 40% increase in crop failures, highlighting the urgent need for effective adaptation strategies. Research conducted by Hao Li, Jessica Keune, Femke Smessaert, Raquel Nieto, Luis Gimeno, and Diego G. Miralles.

Abstract
This research paper investigates the impact of land-atmosphere feedbacks on crop yields in the world's 75 largest rainfed breadbaskets. The study finds that crop failure increases by approximately 40% when both upwind and local land-atmosphere feedbacks result in anomalously low moisture and high heat transport. Water-limited regions show a greater dependence on moisture supply from upwind areas. Understanding these upwind-downwind dependencies is crucial for developing adaptation strategies to prevent food shortages.
