Review of prescribed burning and wildfire burning across Australia: John O’Donnell
John O'Donnell discusses the significance of a graph showing areas burnt by bushfire and by prescribed burning across Australia since 1960.
Desperately seeking big policy ideas for our smallest youngest people
A Charles Sturt University early childhood education expert asks where in the 2022 election campaign is the commitment to big investment and to big policy ideas that ensure free and accessible early childhood education for the long-term? Dr Leanne Gibbs tells ARR.News how the challenges in workforce supply and retention in the ECE sector are even greater in rural, regional and remote areas within Australia.
The koala, unlike science, is in absolutely no danger of extinction: a case study from NSW’s north coast
Vic Jurskis discusses data from historical reports and field surveys and concludes that koalas are in no danger of extinction. ARR.News asked some further questions of Vic.
Koalas: How threatened? Threatened how?
The Australian Rural & Regional News webinar held on 21 April 2022 is now available for public viewing.
Rabobank commentary and report: May 2022 WASDE ‘Outlook on 2022/23 global grain and oilseeds market prospects’
The outlook shows 2022/23 may be the first year since 2012/13 in which the world has to consume less grain than the previous year – due to high prices and low supply, says Rabobank senior commodities analyst Cheryl Kalisch Gordon. “This is forecast to be a drop of only 0.1%, but that compares to average annual growth of 2.1% over the past decade,” she said.
The effects of biochar feed supplementation on GHG emissions and cattle liveweight gain: is it worthwhile?
Nicoli Barnes, UTas. It has been suggested that biochar improves animal health and liveweight gain. It has also been suggested that biochar reduces enteric methane and, by increasing carbon content in the manure, may improve soil carbon over time. Together these effects would theoretically reduce whole farm emissions. In an MLA-funded research programme, we are testing this theory using in a farm experiment near Deloraine, Tasmania.
Australian wineries and vineyards moving ahead in the transition to net zero emissions and to tackle climate change
Sustainable Winegrowing Australia has released its inaugural Impact Report detailing the wide range of sustainable practices being successfully implemented by vineyards and wineries across Australia. The report outlines the program’s first national data set and the significant steps being taken towards net zero emissions for the sector, with 100% of members measuring and reporting their scope 1 and 2 greenhouse gas emissions.
The McGowan logic – sustainable native forest logging not environmentally acceptable, but widespread clearing of the jarrah for bauxite is: Robert Onfray
Robert Onfray gives an in depth examination of bauxite mining in Western Australia, its impacts on the jarrah forests, ineffective anti- mining protests and questions the McGowan government's decision to end native forest logging but support bauxite mining.
Agricultural research cut
Gabrielle Duykers. Localised farm trials in the Limestone Coast and western Victoria will be significantly reduced after a research and innovation body chose to reprioritise its spending ... Historically, the Mackillop Farm Management Group (MFMG) used funds from its members to conduct variety trials in areas throughout the region where there are either no National Variety Trial sites, where nearby trial sites have different growing conditions to those on members' farms, or to conduct specific cropping trials as selected by the committee. Earlier this month the group announced it would cease funding these trials indefinitely, citing rising running and management costs.
New tool helps grain growers preserve beneficial insects on farm
A critical new tool will help Australian grain growers understand what pesticides to select to preserve ‘beneficial’ insects that play a critical role in pest management in the paddock.
Selecting an appropriate baseline: Frank Batini
If we wish to compare current observations with past performance, we need to establish a set of relevant data, or baseline ... Water Corporation’s advertisements claim that “Perth’s rainfall is declining due to Climate change” showing a graph of reduced stream-flows into the reservoirs as convincing proof that “Climate change is real”. Such claims deserve scrutiny.
The impact of China’s Covid lockdowns on Australian agriculture
RaboResearch general manager for Australia and New Zealand Stefan Vogel said, in particular, there are four specific impacts of the lockdowns in China that are set to have increasing ramifications for Australian agribusiness – disruptions to freight logistics, Chinese corn plantings, dairy demand and hog pricing.
Crocodiles are changing their diet, research shows
Scientists have uncovered evidence that suggests the diet of saltwater crocodiles has shifted away from marine prey towards land-based animals. Researchers at Charles Darwin University compared bone samples from saltwater crocodiles killed around the 1960s, held at the Museum and Art Gallery of the Northern Territory, to those of contemporary saltwater crocodiles.
Scientists urge deeper dive into ocean afforestation and seaweed as a carbon storage solution
Two new studies led by Institute for Marine and Antarctic Studies (IMAS, UTAS) scientists provide an approach for accurately assessing the carbon storage capability of seaweed before it is factored into carbon offset initiatives, and highlight the need for further research into the impact of extending seaweed forests offshore into oceanic ecosystems.
Rocketing into space from the Territory
The Northern Territory Space Strategy 2022-2026 builds on the success of Territory Space industry 2020 and establishes a vision for the Northern Territory to be recognised as the home of high altitude pseudo-satellites in the Indo-Pacific region, Australia’s premier space launch location and a leading regional centre for ground station facilities.
Flying scientists take off
Some of the country’s leading scientists have taken to the skies in a bid to inspire students across Central Queensland to study science, technology, engineering and mathematics (STEM). Science Minister Meaghan Scanlon said this year’s Flying Scientists trip would be led by former Australian of the Year Professor Ian Frazer AC.
Compost in sponge cities are the answer to building climate resilience: CORE
Research conducted by the Centre for Organic Research & Education (CORE) has developed recycled content technologies that can turn cities and farmlands into Sponges that can adapt to more frequent flooding and drought events to reduce the risk they present to our communities ... May 1st to 7th marks International Compost Awareness Week (ICAW) in Australia.
Fertiliser test strips fine-tune fertiliser decisions
GRDC Agronomy Solutions Director Sean Mason ... says the use of pre-season soil testing results from within paddock zones together with test strips can fine-tune fertiliser recommendations and ensure growers are getting the most bang for their fertiliser buck.
Zounds Professor Zylstra: David Jefford Ward
One of Professor Zylstra’s core beliefs is that withholding fire from south-west Australian eucalypt forests for at least four decades will make those forests less flammable, even in a warming climate. This idea must bring joy to those who have long claimed that frequent, deliberate (prescribed) burning is ‘harmful to biodiversity’.
Deloitte Access Economics Business Outlook: Now for the tricky bit
"Australia sells energy and food to the world, so the tragedy in Ukraine means that our miners and farmers have seen the spoils of war."
Prospects for Australian wheat exports amid the Ukraine-Russia conflict
A Charles Sturt University agribusiness expert suggests Australia can anticipate an increase in wheat exports to countries affected by the Ukraine-Russia conflict and should target those importing nations’ requirements.
Councils urged to seek expert help
Chris Oldfield. When it comes to roads, 'a stitch in time saves nine’ and it is a lot cheaper for councils to look after them, says one of Australia’s leading road research experts, Tyrone Toole. Only in very poor countries has Mr Toole seen bitumen roads ripped up and replaced with gravel ones ... for councils to do such things in Australia, Mr Toole said it would be a sign of “desperation” and “a backwards measure”.
