Lobby group the National Farmers Federation (NFF) has joined forces with Farmers for Climate Action (FCA) to advocate for emission reduction that helps grow agriculture.

NFF president Brent Findlay said it would help influence policy measures on tackling climate change.

The FCA group has drawn farmers from across Australia, who have been through industry-led programs like: Managing Climate Variability funded by research and development corporations, the Victorian Primary Industries Adaptation research group and the Climate Champions Program.

"As a nation we can do more to reduce emissions, and farmers we've surveyed agree on the need to cap the temperature increase because they're seeing the changes on their properties," said FCA committee member Lucinda Corrigan, a cattle breeder and former board director of Meat and Livestock Australia.

"On our farm in the Murray Valley near Albury, 50 years ago the frost would last on the ground for six weeks in winter.

"That's no longer the case and that affects biosecurity."

There are new weeds in the south west slopes of NSW, and the tick born parasite theileria has spread south causing anaemia in cattle.

Across the industries, climate change is having an effect, from a shorter growing season for grain, to earlier harvests in the wine industry, and fishing stocks are being affected by warmer waters.

Ms Corrigan said the FCA was a "broad church" with people keen to make a positive change.

"Our members are interested in everything from how farmers can take part in the current Emissions Reduction Fund, to how we can attract more investment to innovate in adaptation and mitigation, as well as the opportunities that renewable energy represents for farmers and regional communities."

The group was formed less than 18 months ago, and it crowd-funded two young farmers Anika Molesworth and Joshua Gilbert to attend the UN's climate talks in Paris.

Mr Gilbert was the driver of a motion at the NSW Farmers Association in 2015 that reversed a long held scepticism of the science behind climate change.

But this year, Mr Gilbert resigned as chairman of the young farmers citing a philosophical disagreement with NSW Farmers Association's push to change the NSW Biodiversity Act.

Australia is one of more than 100 countries which have ratified the Paris agreement on climate action, which covers 70 per cent of global emissions, and aims to contain the temperature rise to 1.5 degrees above pre-industrial levels.
