Impacts of climate change on irrigated potato production in a humid climate

► A study on the impacts of climate change on potato (Solanum tuberosum L.) yield in England show marginal increases (3-6%) owing mainly to limitations in nitrogen availability. Future potential yields, without restrictions in water or fertiliser, are expected to increase by 13-16%. ► Future irrigation needs, assuming unconstrained water availability, are predicted to increase by 14-30%, depending on emissions scenario. ► The present 'design' capacity for irrigation infrastructure would fail to meet future peak irrigation needs in nearly 50% of years.
