Summary: This research aims to evaluate the environmental impacts of landfill mining with on-site sorting and land application using life cycle assessment. The results demonstrate that excavating landfilled waste and on-site recovery of soil have higher environmental benefits in terms of global warming potential, freshwater eutrophication, human toxicity, and fossil depletion. However, they also have higher impacts in terms of terrestrial acidification, terrestrial ecotoxicity, marine eutrophication, and photochemical oxidation. After composting, land application of recovered soil contributes to environmental offsets in global warming potential, human toxicity, and freshwater eutrophication, while contributing to soil ecotoxicity emissions.

Summary: Eastern Australia's climate is characterized by extreme variability and recurring droughts. An analysis of river gauges reveals a significant decline in annual flow since 1992/93, particularly in the far South coast of New South Wales. Changes in land use and river management have contributed to the reduction in flow, coinciding with an increase in woody riparian vegetation. This increase in vegetation is the largest biogeomorphic change experienced by the SE Australian drainage network in centuries.

Summary: By connecting corridors of river recovery, resilience can be built into river systems to mitigate against future floods and droughts. However, there is a lack of methods to identify where these corridors can be built in river management practice. The Open Access NSW River Styles database provides comprehensive information on geomorphic river condition and recovery potential, which can be used to analyze potential locations for river recovery corridors. The study found significant spatial variability in the types and lengths of connections made across different catchments. These findings provide important guidance for river conservation and rehabilitation activities in practice.

Summary: Natural flood management (NFM) is a nature-based solution that utilizes hydrological and biophysical processes to reduce flood risk. The catastrophic floods in eastern Australia in 2021 and 2022 are used to assess the hydrological properties of these events and investigate whether widespread changes in flood hydrology are occurring. The findings suggest that passive riparian management and NFM measures may be counteracting the severe hydrological effects of floods, highlighting the potential for large-scale implementation of NFM in coastal catchments of New South Wales (NSW).

Summary: Radiocarbon dating of charcoal from the Macdonald River in Australia revealed calibrated ages spanning over 1700 years. The varying ages can be attributed to factors such as the age of living biomass, charcoalisation conditions, and transportation and storage processes. These findings caution against relying solely on radiocarbon dating of charcoal to interpret sedimentary histories and suggest that deposit age may not be reliably determined by charcoal age.

Summary: Radiocarbon dating of charred plant remains is commonly used for dating lake cores and fluvial sequences. However, the charcoal can be older than its depositional context due to various transportation and storage stages. This study revisited samples from the Macdonald River in Australia and found that the inherited age of charcoal fragments could be significantly older than the collection date. Taphonomic factors such as size, shape, and fungal infestation were not effective in identifying the youngest fragments. Only fragments from short-lived materials provided accurate estimation of the collection date. These findings suggest that wood charcoal overestimates deposition age in southeast Australia, and multiple short-lived materials are needed for accurate dating.
