An enzyme-linked immunosorbent assay (ELISA) specific for DDE [1,1-dichloro-2,2-bis(4-chlorophenyl)ethylene] has been used to map DDT [1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane)] residues in the top 10 cm of soil in three river valleys of northern New South Wales, Australia. Despite being almost 20 years since DDT was last applied for cotton growing in(More)
The potential environmental suitability and economic viability of growing two biodiesel crops in marginal regions of Australia were explored. Firstly, we used spatial analysis techniques to identify marginal agricultural regions suitable for growing pongam (Pongamia pinnata) and Indian mustard (Brassica juncea), and determined the base socioeconomic(More)
Classifying remote sensing imageries to obtain reliable and accurate land use and land cover (LULC) information still remains a challenge that depends on many factors such as complexity of landscape, the remote sensing data selected, image processing and classification methods, etc. The aim of this paper is to extract reliable LULC information from Landsat(More)
Feral pigs (Sus scrofa) are an invasive species in Australia. Their negative impact on conservation values has been demonstrated, and they are controlled in many areas in the rangelands of Australia. However, they are usually controlled over small, often ad hoc management units (MUs), and previous research has revealed that these MUs can be inadequate.(More)
Salt-affected soils are a major threat to agriculture especially in the semiarid regions of the world. The effective management of these soils requires adequate understanding of not only how water and, hence, solutes are transported within the soil, but also how soil salinity and sodicity spatially interact to determine soil structural breakdown. For(More)
Environmental disruption from mining activity has increased markedly in the 21st century leading to increased emphasis on reconstructing natural environmental processes in post-mining landscapes. We present simulation and assessment approach to designing post-mining landforms at Ranger Uranium Mine in Northern Australia. A mine landform design was developed(More)
It is well known that the world is rich with soil data resulting from the efforts of past soil surveys. However, the majority of these data is largely unused. These legacy soil data come in the form of soil maps, soil survey reports, soil profile descriptions, and/or in the format of antiquated “card catalogue”. These data provide many benefits including(More)
