Lowering methane emissions through the use of Asparagopsis seaweed as a feed supplement has become a reality, following its first commercial sale in early June, according to Meat & Livestock Australia (MLA) and FutureFeed. The first commercial sale of Asparagopsis feed supplement in Australia by CH4 Global is a significant step forward for the industry.

A new study led by the University of South Australia indicates tens of thousands of wind turbine blades will end up in landfill by the end of the decade unless end-of-life programs are established soon. The study, led by  Professor Peter Majewski, highlights the challenges of recycling wind turbine blades, which are made of either carbon fibre or glass fibre composite material, both of which are expensive to break down, with the recovered materials having minimal market value.

The NSW country town of Leeton is about as far removed as possible from Afghanistan – geographically, culturally, politically and religiously – but it has set the gold standard for how Australia can successfully integrate refugees into local communities.

The risk of an FMD outbreak in Australia has been given a probability of 9% (1%/19%). The advent of FMD in Indonesia increases the likelihood of an incursion into Australia. We should not have waited until FMD or any disease was close to bring attention to the risk of exotic diseases ... In the event of an outbreak of FMD, we would immediately lose a large number of our premium livestock markets. The longer an outbreak takes to be controlled, the longer we are shut out of premium markets.

Extreme fire weather days have increased in Australia by 56 per cent over the last four decades, according to new research from an international team of scientists, including CSIRO, Australia’s national science agency ... CSIRO researcher, Dr Pep Canadell, said an increase in fire weather trends translated to an increase in the number of Australian bushfires.

The first of a three part series by Philip Hopkins. Sharing information globally about the causes and impacts of destructive bushfires in an era threatened by global warming drew about 360 people to an international conference in Melbourne in June. Fire & Climate 2022, presented by the International Association of Wildland Fire in partnership with Natural Hazards Research Australia, concentrated on the most significant forces shaping wildland fire today.

A recent CSIRO study has found that Australians are more likely to support the use of gene drive technology for feral cat management if there was a perceived problem of invasive species in one’s local neighbourhood ... "Feral cats are an ideal candidate for gene drive research given that their reproductive rates are up to three litters a year, which greatly outpaces conventional measures" : Dr Owain Edwards.

The National Parks and Wildlife Service has a team visiting Narrandera this week to conduct aspects of koala research in the Narrandera Reserve ... Dr Joanne Connolly from Charles Sturt University's proposed research will involve further steps in the research proposal to establish a koala research centre in Narrandera and will complement and build further on the data being collected by the team from the Koalas Biodiversity and Ecological Health Branch of NPWS.

“Comparing soil health in sugarcane growing districts to soil health in pasture, horticulture and cropping regions shows just how unique those sugarcane soil systems are. Many cane growers may not have measured their soil health before but with commodity prices remaining strong in this regulated market, we’re seeing cane growers becoming increasingly interested in soil health" : Rob Dwyer, Incitec Pivot Fertilisers agronomist.

Fergus O'Sullivan, History Guild. The Battle of Cape Spada was a short, violent encounter on the 19th of July, 1940 where the cruiser HMAS Sydney of the Royal Australian Navy sank one Italian cruiser and severely damaged another off the coast of Crete. In this article, we go over the events of that day, as well as what life was like for the crew of the ship.

Good rainfall and high commodity prices have driven strong farm financial performance for 2021-22. Executive Director of ABARES Dr Jared Greenville said cropping farms had reported higher than average cash incomes over the last year.

Citizen science has made an important contribution to an FRDC-funded project to predict the impact of climate change on three fish species of increasing recreational and commercial importance in Tasmania ... Data from the project was gathered from several sources, including fish frames (skeletons) donated by recreational fishers at 16 drop off points around Tasmania, which yielded 801 frames in the 24 months to July 2021. Frames were also donated by commercial fishers and fish processors.

Rodney Stevens. As the Clarence Valley was bathed in warming winter sun last week, Associate Professor Hannah Power was relishing the conditions more than 20 kilometres offshore, sampling the seafloor for signs of tsunami potential. Dr Power was among a team of 32 scientists and university students who were in Clarence Coast waters over the past week in CSIRO Research Vessel Investigator, mapping the ocean floor to investigate the East Coast tsunami risk.

Results of the quarter two Rabobank Rural Confidence Survey, reveal optimism about high agricultural commodity prices and the prospect of a third consecutive bumper grains harvest has been reined in by the increasing cost of vital farm inputs such as fertiliser, fuel, freight and machinery and broader inflationary pressures in the Australian economy.

While global milk production is set to have decreased for at least four consecutive quarters from Q3 2021 to the current quarter Q2 2022 expectations of weakening demand are creating a scenario for moderate price declines in dairy commodities during the second half of 2022, Rabobank says in its latest global Dairy Quarterly report.

An invited presentation by Associate Professor Matthew Harrison from the University of Tasmania presents a summary of recent research in climate change adaptation and greenhouse gas emissions mitigation for the agriculture sector. Questions are welcome.

First-mover companies around the world are taking the next steps to meet their emissions reduction goals and beginning to release climate-neutral beef products on to shelves, Rabobank says in its latest global Beef Quarterly report.

New research by Australia’s national science agency, CSIRO, shows Australian coastal plastic pollution has decreased by 29 per cent, the surprise discovery revealed as part of a broader project assessing waste reduction efforts.

Delegates at the  River reflections  annual water conference heard about the challenges we all face due to climate change and how we must work together to make the Murray–Darling Basin ready for a more variable, drier and hotter future. In his address,  The future of the Murray–Darling Basin,  Murray–Darling Basin Authority Chair Sir Angus Houston said we must adjust our approach based on what we have learnt and continue in partnership with experts, communities and First Nations People.

Evidence of an important koala population in Kosciuszko National Park has been revealed by new surveys ... conducted in November 2021 and February 2022 that recorded male koalas at 14 sites within the park’s Byadbo Wilderness Area. “This is good news because until these recent surveys, there had only been 16 recorded sightings of koalas in Kosciuszko in more than 80 years,” Mr Griffin said ... ARR.News asks some questions of the Minister.

A new state of the art gene bank has been opened in Morocco by the  International Center for Agricultural Research in the Dry Areas (ICARDA). Gene banks play a crucial role in providing the materials required by researchers and global breeding programs to develop high yielding, resilient and climate adapted crops.

Warwick O'Neill. Imagine you’re a young 20 year old bloke. You’ve just struggled across sixty miles of some of the toughest terrain on earth. You’ve had bugger all training, your weapons are obsolete because you’re “just Militia” and all the best stuff is being used by the Second AIF in North Africa. But here you are on the pointy end of the attempt to defend Australia from direct attack.
