"Staffing rural and regional schools remains an intractable problem in Australia, and there are no one size fits all solutions,” write Professors John Buchanan and Paul Burke of the University of Technology Sydney. They are the authors of a new study in the  Australian Journal of Education  that evaluates incentives used to attract teachers out of Australia's cities.

Asparagopsis is a native Australian seaweed rich in bromoform. It’s the bromoform compound within the seaweed feed supplement that reduces livestock methane emissions by up to 98 per cent. So why isn’t Asparagopsis a commodity of large scale? One of the key issues is its availability; but one scientist is on the brink of a discovery which could drive a surge in demand for this seaweed biomass.

When I first visited Kalgoorlie last October, I read about the Great Western Woodlands. Based on their distribution and extent, they certainly are “Great”. The Woodlands cover nearly 16 million hectares south and west of Kalgoorlie ... Until recently, though, the woodlands were known as the Goldfields Woodlands. Why the name change?

Vanilla is an emerging rural industry in Australia with huge potential. There is one major roadblock which is preventing the spice from really taking off. The orchid relies on hand-pollination and it’s labour intensive. Julie Sosso has a plan to change this.

If we as a society don’t identify all the non-climate, climate change, weather and drought factors that influence the extent, intensity and severity of major bushfires across Australia and action associated opportunities, Australia will continue to have more of the same disastrous bushfires, impacting on communities, fire fighters, flora, fauna and the environment.

Another 400 hectares has been secured to protect koalas in the Coomera Connector corridor. Premier Annastacia Palaszczuk said the Greenridge property at Pimpama, within the Gold Coast's Koala Priority Area, is one of the largest private, and suitable, land holdings close to stage one and future stages ... “The additional 400 hectares is next to the PRCA, creating almost 900 hectares to protect the local koala population and improve their home range and connectivity well into the future.”: Premier Annastacia Palaszczuk

Turtles are a key environmental value and attraction for both tourists and residents in the Lord Howe Island Marine Park ... Given marine turtles are valuable and threatened species, understanding both local and global threats to their populations is important. Injured and dead turtles are occasionally seen in the LHIMP and these observations can help identify which threats are having the greatest impact on turtles in the marine park.

The Crocodile Management Independent Expert Evaluation Committee – chaired by Queensland’s Chief Scientist, Professor Hugh Possingham – made 22 recommendations for improving estuarine crocodile management in Queensland ... The department has accepted each of the committee’s recommendations, with several recommendations already being implemented.

The latest quarterly Consumer Price Index (CPI) data, has shown a continuing rise in Australian food price inflation, with June 2022 quarter food prices increasing 5.9 per cent compared with the June quarter last year. Rabobank senior food retail analyst Michael Harvey said this was the highest year-on-year increase seen in food prices in the CPI since the September quarter 2011, when yearly food price inflation had peaked at 6.4 per cent.

Pilbara Ports Authority and Yara have signed a collaboration agreement for a feasibility study into ammonia bunkering in the Pilbara ... an important step on the path towards a net zero shipping industry and will assess potential demand, feasibility, infrastructure requirements, safety considerations and the establishment of ammonia bunkering guidelines.

Many Australian farmers are still battling to get grain crops planted due to wet conditions, while the global wheat outlook price remains elevated and buyers will be hoping prices will ease as the northern hemisphere supply comes to market.

Australia will need to both consume and export more avocados as the nation’s growers navigate a period of soaring production growth over the coming five years, specialist agribusiness bank Rabobank says in a new report. This year alone, ‘per capita (person) supply’ of avocados is estimated to be up 26 per cent on the previous 12 months to 4.8 kilogram – equating to 22 avocados per Australian.

A 12 month trial on a cotton farm just outside the rural town of Goondiwindi Queensland in Australia has shown it’s possible to divert large amounts of cotton textile waste at end of life from landfill with no harm done to soil health or cotton yields. Project collaborators are confident that with a solid business plan and more research, returning shredded cotton products to cotton fields could soon offer benefits to soil health, and a scalable solution to the massive global problem of textile waste.

Amid Australia’s first Varroa Destructor Mite outbreak, the grower-owned research and development corporation Hort Innovation has joined forces with the University of Sydney to develop a world-first hormone-based pesticide that is safe for honey bees but fatal to Varroa mite. As part of the $1.2M initiative, scientists will create molecules that selectively bind to and interfere with the hormone receptors of Varroa mite and fellow honey bee pest, small hive beetle, interfering with reproduction, development, and behaviour.

Following the release, the Victorian Regional Forest Agreements (RFA) - Major Event Review of the 2019- 2020 bushfires, the peak national organisation representing over 1,000 forest scientists and professionals have called for active and adaptive forest management to be implemented as a matter of urgency. President of Forestry Australia, Bob Gordon said the organisation has been calling on all governments to prioritise and invest in a year-round active and adaptive management approach to forest management, regardless of tenure.

“The Mulloon Institute heartily welcomes the Environment and Water Minister Tanya Plibersek’s calls for structural reform and new environmental legislation,” said Mr Gary Nairn AO, Chairman of the Mulloon Institute and former Federal Liberal MP. The Institute restores degraded landscapes across Australia for improved agricultural productivity, enhanced environmental outcomes, improved biodiversity including habitat for threatened species, and greater community resilience to drought, bushfire and flood.

Sadly, death and destruction will continue to escalate whilst governments rely on advice from academics and firechiefs and give them increased funding after every disaster. Sustainable fire management would be very much cheaper and better.

Some academics are happy to comment in areas where they have no expertise or local knowledge. In contrast, the views of locals with years of practical management experience are mostly ignored.

Philip Hopkins. Bushfire policy needs to be driven by rigorous science underpinning politics if the landmark federal-state national bushfire management strategy is to be successful, according to one of the nation’s leading bushfire experts. Dr Kevin Tolhurst, AM, Associate Professor of Fire Ecology and Management at Melbourne University, said fire management was dominated by alternate paths based on politics and science.

Narrandera's iconic koalas are at the forefront of an exciting research project to assess the population, health and genetics of the free-ranging colony. The project, led by National Parks and Wildlife Service, swung into action last month when a six-member team of specialist veterinarians, NPWS staff and a professional tree climber arrived in town to undertake field work.
