Using machine learning to understand how the world’s microbiomes are changing due to climate

Shotgun metagenomic sequencing has become commonplace when studying microbial communities and their relationship with the health of our planet, and their direct effects on our own health. Currently, there are >180,000 shotgun metagenomes publicly available, but until recently trying to treat these data as a resource has been challenging due to its extreme size (>700 trillion base pairs).Recently we have developed a tool that can efficiently convert this base pair information into a straightforward assessment of which microorganisms are present …

Shining a light on climate-relevant aerosol over the Southern Ocean

Current climate models strongly underestimate the proportion of solar radiation that is reflected away from earth over the Southern Ocean.Marine aerosols play an important role in this process by both directly scattering this incoming radiation and affecting cloud properties. However it is challenging to deploy suitable instruments and obtain detailed analysis of aerosols in this remote region.This research investigates whether optical measurements can offer a simplified method to characterise the aerosol on the basis of wavelength-dependent differences in light scattering.

International Environmental Law and Politics

Many environmental issues are globally significant problems and countries have to engage and interact with each other to resolve them despite having different domestic priorities. Current challenges around climate, land degradation, biodiversity loss, and plastics are just some of the issues that are influenced by international standards, agreements and institutions.

Decision support systems for mitigating urban extreme heat effects

Extreme heatwaves and other extreme weather events are contributing to the fragility of cities and urban infrastructure, which requires urgent attention (Kamruzzaman et al., 2018). Urban heat islands are an exemplar for metropolitan fragile areas, which exacerbate the impact of climate change and global warming on natural hazards, such as wildfires, storms, floods, and droughts, which pose a critical threat to Australian and international communities (Degirmenci et al., 2021). Decision support systems (DSS) can help urban planners and policymakers to …

Climate vulnerability of nut and pulse food systems in Australia

Arable land, water resources and biodiversity are under pressure from increased human populations and resource needs. On top of that, natural and agri-food systems are rapidly changing due to natural disturbances, with climate change likely to increase the impacts of extreme events like drought and wildfire.With climate change, negative impacts on agriculture are predicted with disruptions to food supply; many ecosystems have already been impacted by increased frequency and severity of extreme fire events; coral reefs will be threatened by …

Keeping carbon – ensuring soil carbon gains through improved grazing management persist through drought in Australia's tropical and semi-arid grasslands

Drought is the biggest barrier to sequestering soil organic carbon (SOC) in soils over the long-term. While options are limited during dry periods, how we manage our pastures prior to drought can influence the resilience of SOC to losses and enhance recovery.

Using time-controlled grazing to sequester carbon in Queensland rangelands

Time-controlled grazing (TCG), or cell grazing is a management strategy in which cattle are stocked and rotated across small paddocks or “cells” according to fodder availability. Grazing takes place in short durations at high stocking densities, in an effort to mimic the grazing patterns of wild ungulate herds.This management strategy has gained traction in recent years due to claims that it improves both pasture productivity and diversity, whilst also increasing long-term carbon pools. Limited data is available on the impact …

Engineering response to climate emergency with zero carbon footprint for building construction by 2030 using circular economy principles

We as engineers can make a contribution to address the current climate emergency.The Australian Sustainable Built Environment Council report (2016) found that if Australia's built environment sector reaches zero carbon emissions for the operation of residential and commercial buildings by 2050, it could contribute 28% to the country's 2030 emissions reduction target and save up to AU$20 billion.In this project we will consider the application of the circular economy, which is based on the principles of designing out waste and …

Ecological interactions in Antarctic ecosystems

Antarctic and sub-Antarctic terrestrial ecosystems are dominated by mosses, lichens, invertebrates and some vascular plants. Marine vertebrates (penguins, seals, seabirds) also play an important role in driving terrestrial processes. All these species are influenced by many environmental and biotic factors, including interactions between species. Determining the impacts of climatic and environmental change on Antarctic and sub-Antarctic biodiversity requires greater understanding of these interactions.Ecological data on species interactions and the drivers of these interactions are an essential part of Antarctic and …

Designing smart cities for more-than-human futures

Cities are changing across the globe. Climate change, rapid urbanisation, pandemics, as well as innovations in technologies such as blockchain, AI and IoT are all impacting urban space. One response to such changes has been to make cities ecologically sustainable and 'smart'. The 'eco smart city', for instance, uses networked sensing, cloud and mobile computing to optimise, control, and regulate urban processes and resources. From real-time bus information, autonomous electric vehicles, smart parking, and smart street lighting, such initiatives are …
