Impact of climate change on food production could cause over 500,000 extra deaths in 2050

Public Release: 2-Mar-2016
Impact of climate change on food production could cause over 500000 extra deaths in 2050
By 2050, reduced fruit and vegetable intake could cause twice as many deaths as undernutrition * Three-quarters of all climate-related deaths due to changes in food production estimated to occur in China and India
The Lancet

Climate change could kill more than 500000 adults in 2050 worldwide due to changes in diets and bodyweight from reduced crop productivity, according to new estimates published in The Lancet. The research is the strongest evidence yet that climate change could have damaging consequences for food production and health worldwide.

The modelling study, led by Dr Marco Springmann from the Oxford Martin Programme on the Future of Food at the University of Oxford, UK, is the first of its kind to assess the impact of climate change on diet composition and bodyweight, and to estimate the number of deaths they will cause in 155 countries in 2050.

"Much research has looked at food security, but little has focused on the wider health effects of agricultural production", explains Dr Springmann. "Changes in food availability and intake also affect dietary and weight-related risk factors such as low fruit and vegetable intake, high red meat consumption, and high bodyweight. These all increase the incidence of non-communicable diseases such as heart disease, stroke, and cancer, as well as death from those diseases."[1]

"Our results show that even modest reductions in the availability of food per person could lead to changes in the energy content and composition of diets, and these changes will have major consequences for health," adds Dr Springmann.
