Sir Charles Godfray, Director of Oxford Martin School and a leading population biologist, recently spoke at the City Food and Drink Lecture in London about the challenges faced by the global food system. While considerable progress has been made in recent decades to lift people out of poverty and improve their diets, the world’s population is expected to grow to ten billion by the end of the century, necessitating a 30-60% increase in calories produced.
One solution to the problem of feeding the growing global population, according to Godfray, is sustainable intensification. This approach involves increasing production on agricultural land using sustainable methods, including genetic and ecological intensification, with an emphasis on retaining biodiversity and using land for carbon sequestration.
However, there are obstacles to achieving a sustainable food system, including military conflict and geopolitical instability, both of which contribute to hunger and malnourishment in some countries. In addition, animal agriculture is a significant contributor to climate change, and while reducing meat and dairy consumption is necessary to reach net zero emissions, it must be done in a way that supports the livelihoods of those who depend on livestock farming.
Finally, Godfray warned against deglobalisation in the food system, which could lead to less reliable supply chains and higher transaction costs. Despite these challenges, he emphasized the importance of taking a non-judgmental approach to changing the global food system, focusing on solutions that balance economic, environmental, and social concerns.
