By 2050 the United Nations (UN) predicts a world population of 9.7 billion compared with 8 billion in 2022. Increases in food and energy production and the supply of fresh water will be needed to sustain this population, whilst reducing greenhouse gas emissions to limit global warming. The average global temperature is likely to be 2 to 3 degrees Celsius above that in pre-industrial times, unless there is a greater sense of urgency following the UN Climate Change Conference (COP26) in Glasgow in 2021, which still wanted to limit the rise to 1.5 degrees. There is also increasing concern about the loss of biodiversity on Earth from human activity, including farming, as seen in the outcomes of the UN Biodiversity Conference (COP15) in Montreal in 2022. More encouragingly, on 1 December 2023, 134 countries at COP28 in Dubai endorsed the landmark sustainable agriculture, resilient food systems and climate action declaration which put food systems transformation on the global climate agenda. “While food systems are vital for meeting societal needs and enabling adaptation to climate impacts, they are also responsible for as much as a third of global greenhouse gas emissions.” A warmer climate and loss of biodiversity will make life more difficult for humankind; but can potatoes at least help with food security? It is a scientific and technological question set in a political, economic and societal context. It has arisen because potatoes have made the journey from wild species to global food crop.
