The latest issue of the Proceedings of the RSV features papers from the 2021 ‘Stewardship of Country’ Symposium, which delivered presentations across multiple domains of land management practice and scholarly expertise, representing an historic collaboration between Aboriginal and Torres Strait Islander experts, industry practitioners and thinkers. The series posed the question: who are we becoming, as Australians faced with an increasingly unpredictable and challenging future?
In 2015 the United Nations General Assembly declared 11th February as a day to celebrate, recognise and encourage women and girls in STEM fields around the world! This initiative hopes that increased visibility will strengthen interest and support for the next generation of girls who want develop their passions for science.
Human activities have released significant quantities of carbon dioxide into the atmosphere. As a greenhouse gas, the more carbon dioxide emitted, the warmer our planet becomes. Partly mitigating these impacts, plants recover 30% of atmospheric carbon via photosynthesis. Using energy from the Sun, they combine carbon dioxide with water to form sugar and oxygen. When the chemical reaction is reversed, carbon returns to the atmosphere – either by cellular respiration in plants and animals, or the burning of coal, wood, or gasoline. Soil scientist Dr Samantha Grover explains that one way of preventing carbon dioxide from returning to the atmosphere is keeping it sequestered in the ground. In fact, there is two-to-three times more carbon in soil than in the atmosphere.
Senior Climatologist Dr Lynette Bettio explains that soon we will no longer be considering how we get through a single intense year, such as 2019, but how we can make it through a stretch of years with no respite. The climate has been set on a warming path – the long-lived greenhouse gasses that are in the atmosphere and the extra energy soaked up by oceans have secured the warming trend continuing for the next few decades. So the Bureau of Meteorology and CSIRO are investing a lot of effort to solve these problems, knowing the sooner we take action, the sooner we will see a divergence from the alarming projections in current climate models and simulations.
A multi-disciplinary panel gathered to discuss what they see as inspirational for scientists, governments and communities to take action in response to COVID-19, devastating bushfires, and systemic racism and social unrest. Before the pandemic we were amongst the unbridled fires, lush landscapes were blistering, and communities came together to offer donations and support to rebuild towns that were destroyed. During the pandemic and in lockdown we feel as if we’re in a snow dome. Gaps in wealth, age, sex, age and disability became highlighted and people marched forcefully with thunder in response to social injustice. Once we emerge, we hope to have better communication with scientists and vigorously carve out a new equilibrium.
