Grapes don’t ripen the way they used to. As temperatures climb, they are getting sweeter faster.
Winemakers find that by the time the crop achieves the right colour or level of tannins, the grapes contain more sugar. More sugar means heavier, more alcoholic wine. At the same time, drinkers are preferring lighter wines Continue reading Making wine in a warming world
China and Australia can dramatically boost wheat yields and improve food security by unlocking the genetic potential within the hundreds of wheat varieties grown in the two countries. That’s the promise of the latest collaboration between wheat researchers in the two countries.
Chinese farmers have been growing wheat for at least 4,000 years. Crop yields per hectare are now nearly 10 times higher than in 1960 and China is now the largest wheat producer in the world. But wheat researchers say we can do more.

Soils are an important reservoir for carbon, as they contain nearly double that found in the atmosphere and vegetation combined. Agricultural practices have degraded soil carbon stocks, so there is a large potential for atmospheric carbon to be sequestered in soils.

A diet that includes more resistant starch, a kind of fibre that feeds good bacteria in the large intestine, can make it less common. Resistant starch helps improve gut health and reduces the risk of conditions such as diabetes, obesity, heart disease and cancer.
Since 2006, CSIRO scientists have been working in a joint venture with French company Limagrain Céréales Ingrédients and the Grains Research and Development Corporation to develop wheat with more resistant starch. Continue reading Wheat that’s good for guts
Griffith University PhD student Amanda Neilen has discovered how to stop cow urine running off our paddocks into rivers and creeks.
A new approach to horticultural spraying could be the result of a collaboration between design students from Kyoto Institute of Technology and Swinburne University in Melbourne.
“Yanmar is a manufacturer of farm machinery, and they asked us to solve a big problem for grape-growers,” says Natsumi Takamatsu, a design student at Kyoto.
“What we developed was a sprayer to mitigate the drift of sprayed agricultural chemicals. Really it was the actual viticulturists when we interviewed them and they were saying things like ‘If only I had something like this.’”
“Australia and Japan enjoy the seasons at opposite times of the year so we can conduct field research in the vineyards all year,” says Yoshiro Ono from Kyoto Institute of Technology.
Harnessing the sun and improving agriculture
Mitsubishi Heavy Industries have built a pilot concentrated solar power plant in Yokohama. It uses CSIRO technology now being manufactured by South Australian company Heliostat SA.
“We’re making seven-and-a-half-metre square solar mirrors,” says David Linder-Patton, the CEO of Heliostat SA.
They focus the sun’s energy into a tower receiver that generates heat which can be used in industries such as steel manufacturing, brick processing and mineral refining.
The Mitsubishi plant will test their technology on receivers they have developed and also CSIRO’s suntracking technology and heliostat manufacturing.
“Working with companies the size of Mitsubishi helps us to get to industrial scale a lot quicker than we could do otherwise,” says David.
The science underpinning modern farming has enabled our farmers to become more efficient, and more profitable.
Take grain for example. American farmers grow over 440 million tonnes of grain each year. Australia produces about 40 million tonnes. Together that’s about one-sixth of global grain production. Good science has contributed to a tripling in grain production over the past half century.
Both nations export to the world. But whenever we store and transport grain the bugs bite. The latest collaborative research between our two nations is changing that.
