The study indicates a future decline in PEI potato yields due to climate change


The journal published a study conducted by the University of Prince Edward Island's Canadian Center for Climate Change and Adaptation, along with the Faculty of Sustainable Design Engineering and the Ministry of Agriculture and Lands Groceries. This research uses advanced climate models to predict the effects of global warming on potato production in Prince Edward Island (PEI), a leading potato-growing region in Canada. The study, titled “Assessing Future Climate Change Impacts on Potato Yields – A Case Study for Prince Edward Island, Canada,” points to a possible dramatic decline in potato yields by the end of the century due to climate change.

Using the Decision Support System for Agrotechnology Transfer (DSSAT) along with the latest IPCC climate models, the research team, including Xiuquan Wang and colleagues Toyin Adekanmbi, Sana Basheer, Rana Ali Nawaz, Tianze Pang, Yulin Hu and Suqi Liu, predicts a decline Potato yields range from 6-10% in low emissions scenarios to 48-60% by the 2070s, potentially reaching an 80% reduction by the 2090s in high emissions scenarios. These projections underscore the vulnerability of the PEI potato industry to climate change and highlight the importance of adaptation strategies.

The study highlights the crucial role of changing climate conditions such as temperature increases and variable rainfall on potato growth. This suggests that despite some benefits of higher CO2 levels, lower rainfall significantly impacts yields. The research argues for the development and implementation of climate adaptation measures, including optimizing agricultural practices and introducing additional irrigation systems.
