This project aims to tackle the global problem of land degradation with approaches to policy design that combine qualitative and quantitative impact evaluations. By 2050 more than 90% of the Earth’s land area will be affected by human exploitation. Timely action is imperative in order to avoid, reduce, and reverse degradation, especially through land clearing. Intended outcomes include evidence-based policy recommendations to curtail land degradation: which interventions to apply, where, when, and why. Among expected benefits are enhancements to how we design and implement environmental interventions, improve wildlife habitats, conserve biodiversity, and ensure continued provision of nature’s benefits in Australia and internationally.Read moreRead less

Remediation of PFAS contaminated soil using soil washing and immobilisation. This project aims to assess the applicability of soil washing and immobilisation as cost-effective techniques for the remediation of per- and poly-fluroalkyl substance (PFAS) contaminated Australian soils. The project expects to establish the efficacy of the remediation of a range of PFASs, including many polyfluorinated precursors of perfluorinated, chemically-persistent legacy pollutants which are of concern. The proj ....Remediation of PFAS contaminated soil using soil washing and immobilisation. This project aims to assess the applicability of soil washing and immobilisation as cost-effective techniques for the remediation of per- and poly-fluroalkyl substance (PFAS) contaminated Australian soils. The project expects to establish the efficacy of the remediation of a range of PFASs, including many polyfluorinated precursors of perfluorinated, chemically-persistent legacy pollutants which are of concern. The project will provide a scientific basis for understanding the benefits and limitations associated with soil washing and immobilisation techniques and a more comprehensive understanding of future liabilities associated with formation of PFASs from precursors remaining in remediated soils. Collaboration with stakeholders will ensure benefits are captured both commercially and environmentally, as well as removing a potential and on-going health threat to communities exposed to these contaminants.Read moreRead less

An international environmental history of the 'world ocean', 1950s-2000s. This project aims to investigate the ways in which states, international organisations, and international communities have engaged with the ‘world ocean’ as a natural environment from the 1950s to the 2000s. In the context of current environmental and geopolitical challenges for the ocean, this project will analyse how these actors built institutions, communities, and territories in and for the ocean environment as a found ....An international environmental history of the 'world ocean', 1950s-2000s. This project aims to investigate the ways in which states, international organisations, and international communities have engaged with the ‘world ocean’ as a natural environment from the 1950s to the 2000s. In the context of current environmental and geopolitical challenges for the ocean, this project will analyse how these actors built institutions, communities, and territories in and for the ocean environment as a foundation for generating knowledge and claiming power, rights, and resources. By understanding the structures and origins of contemporary ocean ideas, spaces, and institutions, this project aims to benefit current efforts to create resilient ocean environments and communities at the international scale.Read moreRead less
Reproducibility and open science in environmental research. The goal of this project is to improve the reproducibility and transparency of environmental science. Disturbingly low levels of reproducibility have recently been uncovered in other disciplines, and there are good reasons to suspect the same conditions in environmental science.

The goal of this project is to improve the reproducibility and transparency of environmental science. Disturbingly low levels of reproducibility have recently been uncovered in other disciplines, and there are good reasons to suspect the same conditions in environmental science. However, it has thus far been excused from evaluation because of the large spatial scales, long time horizons and dependencies among processes that prohibit direct replication of empirical field research. The project plans to assess the reproducibility of environmental research and develop systematic review methods that account for bias in published research. In this way, it seeks to contribute to the standards for statistical inference and reporting in the discipline, and facilitate a cultural shift to ‘Open Science’ to ensure a more reliable evidence base for environmental decisions.

PFAS transport through landfill clay liners enhanced with proteins. Per- and polyfluoroalkyl substances (PFAS) are a group of environmentally persistent, man-made chemicals found likely to be carcinogenic in humans. Due to their non-stick, water and stain repellences, PFAS have long been used in everyday products (food wrappers, carpets, furniture etc.) which end up in landfills. As it is currently unknown how PFAS move through the various components of landfill barriers, their fate and transpor ....PFAS transport through landfill clay liners enhanced with proteins. Per- and polyfluoroalkyl substances (PFAS) are a group of environmentally persistent, man-made chemicals found likely to be carcinogenic in humans. Due to their non-stick, water and stain repellences, PFAS have long been used in everyday products (food wrappers, carpets, furniture etc.) which end up in landfills. As it is currently unknown how PFAS move through the various components of landfill barriers, their fate and transport has become a priority for the regulators of Australia’s landfill sites according to the Australian 2018 PFAS National Environmental Management Plan. This research will determine PFAS transport through common clay barriers enhanced with proteins which have been shown to be an excellent sorbent for PFAS.Read moreRead less

This project aims to determine how fisheries compliance can be improved with behavioural interventions. Poaching is the most tenacious problem hindering sustainable fisheries worldwide, yet efforts to reduce non-compliance often fail due to limited understanding of how to influence behaviour. This project will draw on key theories and methods from behavioural science to empirically assess how social norms interventions influence fisher compliance in a range of coral reef fisheries. This will significantly improve our understanding of how to lever psychological, social, and cultural dimensions to reduce poaching. Ultimately, this project will contribute practical guidance to influence behaviours in fisheries and other environmental contexts.Read moreRead less
