In this review, John O'Donnell explores 19 town and city bushfire disasters, ranging from bushfire impacts of the early settlements in the 1851 Victorian bushfires to bushfires in 2021, a period covering 170 years. Readers can assess bushfire preparation in relation to their own and other towns and cities and consider if bushfire preparation is well managed, has improved after earlier bushfires and if it has improved since the 2019/ 20 bushfires.

A compact, lightweight sensor system with infrared imaging capabilities developed by an international team of engineers could be easily fitted to a drone for remote crop monitoring. This flat-optics technology has the potential to replace traditional optical lens applications for environmental sensing in a range of industries.

Production in Australia’s agriculture, fisheries and forestry sectors remains on track to be the third highest on record in 2024-25, supported by an improved seasonal outlook ...

Robert Onfray. While researching for my three-part series on the truth behind the rainforest wars in New South Wales, there was a constant theme in the historical account of utilising one species of rainforest timber. While the cutting of hoop pine (Araucaria cunninghamii) was undoubtedly very extensive in New South Wales, the scale of utilisation in Queensland was even more significant, and one of its primary uses was for butter boxes.

Growing global and local demand for sustainable aviation fuel (SAF) could spell good news for Australian agriculture, with the country’s farmers well placed to provide low- emissions feedstock to be used in future production, according to new industry research ... the largest contribution to cutting aviation emissions over the next decade will come from transitioning to the use of sustainable aviation fuel, which is commonly produced from agricultural products and by-products.

A new farming systems project is set to shed light on how farm management decisions affect profitability and sustainability to help southern region grain growers understand the upside and downside of their decisions. The five-year project involves nine field sites … covering different soil types and rainfall zones in South Australia and Victoria, as well as biophysical modelling and economic evaluation.

Forestry Corporation has today reached an important milestone to explore the potential for windfarms within public pine plantations to contribute to the NSW transition to renewable energy … Neoen, Iberdrola Australia, TagEnergy and Mainstream Renewables Power and Someva Renewables joint venture have been awarded permits to investigate wind farm opportunities in some pine plantations…

Shaped by the highest volume of feedback since its inception in 2018, the 2023-24 annual GenCost report has been released ... GenCost is a leading economic report by CSIRO ... in collaboration with AEMO on the cost of building future electricity generation, storage and hydrogen production in Australia. The latest report introduces a range of changes in response to stakeholder feedback, most significantly, the inclusion of large-scale nuclear for the first time.

Michelago, Bredbo, Adaminaby and Jindabyne residents impacted by bushfires highlighted the importance of bushfire maps showing users their location in relation to a fire risk, while clearly communicating critical information such as direction of fire spread to ensure emergency information is easily understood and followed by communities under threat.

The global dairy market may experience a slower price recovery than previously anticipated, particularly as China shows a reduced need for dairy imports, Rabobank says in recently-released sector research. But, despite this, the overall market outlook remains positive, the global specialist agribusiness bank says in its Q2 Global Dairy Quarterly, titled Searching for Equilibrium.

Mark Poynter, a fellow of the Institute of Foresters of Australia (now Forestry Australia) reviews The Forest Wars. The author, Professor David Lindenmayer, responds ... "The Forest Wars  purports to portray the ‘ugly truth’ about what happens in wood production forests": Poynter ... "As I point out in the book there are some key problems with the industry": Lindenmayer.

The 2024 Rural Bank Australian Farmland Values Report finds that Australian farmland values have now recorded a full decade of unbroken growth. While 2023 saw a rise in the national median price, capping off an extraordinary period for farmland values, it also marked a shift in the market as the pace of growth slowed considerably.

The world has witnessed a surge in interest surrounding superfood Moringa oleifera, a fast-growing tree known for its extraordinary nutritional benefits. Almost every part of the moringa tree, from its high-protein green leaves to its seed oil, is edible and packed with essential nutrients.

Australian farmland prices are set for further growth in the year ahead – but at a slowing pace – Rabobank says in its just-released annual Australian Farmland Price Outlook. The global agribusiness banking specialist says after three consecutive years of "double- digit" growth, the momentum in agricultural land price increases is expected to further slow in 2024, as farm profitability levels come off record highs.

New research on how to treat people with PTSD brought on by the 2022 floods was announced at Southern Cross University in Lismore ... Leading the research is Professor James Bennett-Levy ... The research project has many ‘firsts’ in its approach.

Frank Batini. I have observed patterns of foliage scorch, some tree deaths and then recovery in the northern jarrah forest for 22 years. These can be readily explained in terms of soil depth, water-holding capacity, winter rainfall and summer drought ... My hypothesis is that this forest has repeatedly shown resilience to drought ... This is the “good news”, as opposed to the alarmism of other commentators.

Suzie Christensen. LHI has been the latest site to host field trials for a novel detection method, Phytophthora-sniffing dogs. Staff from the Botanic Gardens of Sydney’s Plant Clinic, and Tate Animal Enterprises, visited the Island ... to conduct searches in the PPP and settlement area using Alice, a Springer Spaniel, trained to detect the soil-borne disease.

Australia’s cattle market is sitting in a "state of balance" – with improved beef production waiting on an increase in demand – but an upside in prices is expected towards the end of the year, Rabobank says in its Australian Beef Seasonal Outlook 2024.
