Angeli Mehta reports on emerging technologies tackling the threats to food security from monoculture, climate change and population growth
We have a problem. By 2050 there will be almost two-and-a-half billion more mouths to feed on planet Earth. To sustain them, we need to produce almost twice as much food as we do now.
Irrigation has been a big contributor to increasing yields, but the challenge of a changing climate means water will not be available where it is needed most.
And farming is itself a big contributor to climate change, generating some 14.5% of global greenhouse gas emissions.
There’s a tremendous urgency around connecting the challenges of human health and planetary health
A burgeoning agricultural sector in the developed world has led to diminishing biodiversity, deforestation, soil and water contamination, and air pollution, while elsewhere subsidence farming denies food security to billions. How can we produce more from our agricultural systems – and produce it sustainably?
“There’s a tremendous urgency around connecting the challenges of human health and planetary health and having a really sustainable food system,” says Diane Holdorf, chief sustainability officer at Kellogg.
“The swirl of risk is going to be coming quickly; there’s a lot of work to be done. It’s...
