Facing down a future with no bananas.
Every single Cavendish banana plant worldwide is genetically identical. This vast monoculture sets them up for disastrous disease outbreaks. But researchers have ideas on how to protect the crop.
Charcoal rot is a relatively unknown disease causing yield losses in crops across South Africa, including maize.
Charcoal rot is associated with yield losses in crucial crops like maize, soybean and sorghum.
The silverlead whitefly is a major agricultural pest.
Invasive species and diseases pose a major threat to agriculture – particularly in the countries that can least afford it.
Beefy problem: livestock emit methane, but the soils where they graze can be much more climate-friendly than cropland.

Eating meat means greenhouse emissions. But the emissions from growing crops may have been underestimated, meaning that a climate-friendly diet isn't as straightforward as simply going vegetarian.
Our modern crops need some help in the immunity department.

Modern agriculture is synonymous with monoculture. That lack of diversity is bad news for plants' natural immune defenses. Researchers are figuring out how to help plants fend off microbes – without pesticides.
Sydney’s farms on the urban fringe produce 10% of the city’s fresh vegetables.
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.
Cassava feeds 800 million people - keeping it disease-free is a must.
Rapid genetic disease screening will be the key to saving East Africa's crops - just as it was during West Africa's ebola crisis.
The world’s driest areas are tipped to get even drier, with potentially worrying implications for soil productivity.
The world's 'drylands' – already home to 38% of the world's people – are set to dry out even more. And that could harm the soil microbes that keep soils healthy and help crops to grow.

Next time you reach for the honey, spare a thought for the other vital insects that pollinate our crops.
Nicotiana benthamiana growing in the wild in coastal northern Western Australia.
Australia's risks losing its valuable native plants that could help solve a global food problem. So do we need new laws to stop the seeds being taken overseas?
Fires, such as this one in eastern Sierra Leone, are an annual occurrence across Africa.
On the African continent, more fire for crops leads to less rainfall.
Children from a village in Papua New Guinea’s Western Highlands Province stand in one of countless sweet potato gardens destroyed by frost across the country, August 2015.
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?
South African’s maize crops are an example of a GMO crop.
Only a few African countries are using genetically modified organisms for their crops.

Vaccines aren't just for animals anymore. Research shows priming plants with pathogen-derived compounds strengthens their immune systems and enhances protection against future attack.
India has been sweltering recently – but plants can cope better than people.

Hardy new grains are being developed that can cope with extreme bursts of heat.
Yellow Rust spores can be seen bursting out of a wheat leaf from the inside, tearing their way through the epidermis.

Africa will be able to feed itself in the next 15 years. That’s one of the big “bets on the future” that Bill and Melinda Gates have made in their foundation’s latest annual letter. Helped by other breakthroughs…
Tractors may have revolutionised farming but to protect biosecurity, farmers could do with some extra help.
New technology to tackle biosecurity challenges down the track is one of the five megatrends identified in today’s CSIRO report Australia’s Biosecurity Future: preparing for future biological challenges…
Different language, same crops.
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…
Laboratory-based genetic modification is relatively new when you consider the centuries of selective breeding that precedes it.
Welcome to GM in Australia, a series looking at the facts, ethics, regulations and research into genetically modified crops. In this first instalment, Peter Langridge describes two GM techniques: selective…
