The Effects of Climate Change on Chinese Medicinal Yam Over North China Under the High‐Resolution PRECIS Projection

Abstract The arid and semi‐arid regions are highly vulnerable to climate change variability. Agricultural production in these is particularly because of its heavy dependence on conditions. Therefore, it important improve the projections future agro‐climatic This study investigates changes agroclimatic conditions for growing Chinese Medicinal Yam (CMY) North China during 2031–2050 under Representative Concentration Pathway (RCP) 4.5 8.5 emission scenarios. It employs high‐resolution data provided by regional model (RCM) Providing Regional Climates Impacts Studies (PRECIS‐2.0). CMY yield producing area simulated Agro‐Ecological Zone model. simulations based newly calibrated cultivar parameters. results show that RCM simulation corresponds better with observations precipitation temperature than general circulation (GCM). Because increased precipitation, going improve. While traditional yam will maintain suitable production, areas further expand northward future. average increase 1,196 1,336 kg DM/ha RCP scenarios, respectively.
