Ensuring the next 10 billion people are fed fairly will require a radical restructuring of global agri-tech.
Farms on Sydney’s fringes supply 20% of the city’s food. That could drop by more than half if urban sprawl isn’t kept in check.
The concerns about genetically modified foods are well known. But when we look at population and climate projections, what happens if we don’t use them to increase our food supply?
Melbourne’s farms currently supply over 40% of the city’s food. But a growing population and urban sprawl mean by 2050 they’ll supply half as much.
Food insecurity is a problem that doesn’t only stem from hunger. It is also a result of eating food that is not nutritious.
Papua New Guinea is now facing a drought and frosts that look set to be worse than 1997, when hundreds of people died. So how can memories of 1997 save lives over the next few months?
We are in the middle of one of the biggest experiments in human history. At its core is the homogenisation of global food systems, which increasingly must deliver the same products to an expanding population…
Rising sea temperatures will threaten fish in equatorial areas in the future, jeopardising food supply for those regions…
Should Australia aim to become Asia’s “food bowl”? How can we help farmers earn more for what they produce? And how can Australia best contribute to global food security? Those are some of the crucial…
Australians are set to munch through half a billion prawns this Christmas. But where do all those prawns come from? And can we feel good as we throw another one on the barbie? About half of the prawns…
Raising livestock accounts for the largest single land-use on Earth. Cattle, sheep and goats, pigs and poultry occupy around 30% of the planet’s land area not covered in ice, generate 40% of the world’s…
Baby penguins can adapt to a variety of diets when primary food sources are scarce, a recent study has found. Despite predictions…
Bottom trawling by fishing fleets has caused widespread concern over the environmental damage done to seabed habitats and marine life. It seems obvious that powerful boats towing large heavy nets that…
Low-dose exposure to hydrogen sulfide has been found to enhance plant growth. When used in small concentrations, the deadly…
