Organic farming mitigates climate change

A 30 year scientific trial shows that organic practices could counteract up to 40pc of global greenhouse gas output.

Organic Federation of Australia chairman, Andre Leu, claims the trial of organic and conventional farming practices has proved that organic practices “can be the single biggest way to mitigate climate change”.

“Scientists at the Rodale Institute in the US have proved that organic farming practices can remove about 7000kg of carbon dioxide from the air each year and sequester it in a hectare of farmland,” Mr Leu said.

According to Mr Leu, the scientists estimated that if all of America’s 100 million hectares of cropland were converted to organic practices, it would be the equivalent of taking 217 million cars off the road.

This is nearly 88pc of all cars in the US and more than a third of all the cars in the world.

Dr Paul Hepperly, PhD, research director at The Rodale Institute and Fulbright Scholar stated: “We’ve shown that organic practices can do better than anyone thought at sequestering carbon, and could counteract up to 40pc of global greenhouse gas output.”

Mr Leu said it was important to note that the research that the amount of CO2 sequestered was based on what had already been achieved through current organic farming practices.

“This is not a theoretical estimate as in some of the tree plantation models or unproven like the millions of dollars being spent clean coal or mechanical geo sequestration trials,” he said.

“This is being achieved now by organic farmers in the US, Australia and around the world.”
