Introduction
Ana Horta currently works at Charles Sturt University, affiliatted with the School of Environmental Sciences and the Institute for Land, Water and Society. Ana does research in Geostatistics & GeoInformatics applied to natural resources management and to health. Her current projects are "Assessing and developing a walkability index targeted to older Australians in regional cities", "Macca's in the Mannus, Macquarie Perch Refuge in the Upper Murray", and "Building agribusiness resilience through improved decison-making".

Article
Full-text available
Wet bulb globe temperature (WBGT) is commonly used to assess human physical activity limits and risk exposure to heat-related injury. Using Australia as a case study location, rates of change in WBGT across a range of temperate to hot and dry to humid climates in response to selected projected climate scenarios were investigated. An established phy...
Article
Full-text available
Infrastructure-induced fragmentation of riverine ecosystems has prompted the need for more effective aquatic restoration efforts globally. Fragmentation assessments have been extensively undertaken to inform connectivity restoration efforts for fish and other aquatic biota, but they have potentially underestimated the extent of fragmentation by fix...
Article
Full-text available
Spatial domains defining either geological models or mineral estimation envelopes are among the few components of the mining life cycle that are not quantitatively assessed to communicate uncertainty or error in mineral resource projects. Recent work has investigated the use of Bayesian approximation methods to assess interpretation uncertainty of...
Article
Full-text available
Sustainability of mining projects is linked to informed investment decisions based on public reporting of exploration and mineral resource estimation results. In Australia, guidelines for public reporting are established by the Joint Ore Reserves Committee reporting code through the JORC Code (2012). Although assessment of uncertainty in the result...
Article
Full-text available
The use of virtual species to test species distribution models is important for understanding how aspects of the model development process influence model performance. Typically, virtual species are simulated by defining their niche as a function of environmental variables and simulating occurrence probabilistically via Bernoulli trials. This appro...
Article
A significant reduction in the costs associated with contamination assessments can be achieved if traditional soil sampling for contaminated-site characterization is complemented by real-time sampling using proximal soil sensors. Real-time sampling using a portable X-ray fluorescence (pXRF) device is a cheap and fast sampling method to provide more...
Article
Full-text available
The financial capacity of the Australian agriculture sector to capture the benefits of the growing food and fibre demands of the burgeoning global population has been questioned, particularly in the face of a projected climate change impacts. This paper reports on the first phase of a multi-stage project that seeks to understand the causes of rural...
Article
The size and intensity of bushfires during the 2019‐2020 Australian season has been unprecedented (Nolan et al., 2020). The fires in south‐eastern Australia were extraordinary in terms of the land area burnt (7.2 million hectares; Figure 1); four times that of the 2019 Brazilian Amazon and 1.8 times the 2017 United States’ fires (Bladon, 2018). The...

Species distribution modelling (SDM) is an important tool for ecologists, but different algorithms and different sampling strategies produce different results. Using virtual species with differing characteristics, this study investigated the effect of sampling strategy choices on SDM predictions across multiple algorithms and species, including the...
Conference Paper
In the mining industry, code compliant reporting standards for public announcements have been developed setting minimum standards for public reporting of exploration results and mineral resources. These include an assessment of the quality and confidence in the data and work carried out since public reporting aims to provide information that is mat...
Presentation
Full-text available
Assessing uncertainty in spatial domains in public reporting of mineral resources to provide quantitative measures of uncertainty.
Conference Paper
Full-text available
It is generally recognized that people in rural Australia and world-wide do worse in terms of health outcomes compared to the urban population. Epidemiological studies rely on large datasets obtained through national surveys but efforts to survey rural populations usually result in small datasets. Hence small datasets are often disregarded even if...
Article
Nowadays there is an increasing effort for raising global awareness for the importance of soils to ensure food security, to improve agricultural and environmental planning and monitoring, and to establish effective and sustainable land management policies to counteract soil degradation. This study presents the INFOSOLO legacy database as the first...
Article
There are tens of millions of contaminated soil sites in the world, and with an increasing population and associated risk there is a growing pressure to remediate them. A barrier to remediation is the lack of cost-effective approaches to assessment. Soil contaminants include a wide range of natural and synthetic metallic and organic compounds and m...
Article
In this study we validated digital soil maps of clay content at different spatial supports; point, 48 m blocks and soil–land use complexes (SLU). The aim being to examine the change in prediction quality with different prediction supports. Digital soil maps of clay content at depths of 0–10 cm, 10–30 cm and 30–50 cm were created using linear mixed...
