Pricing greenhouse gas emissions is a burgeoning and possibly lucrative financial means for climate change mitigation. Emissions pricing is being used to fund emissions-abatement technologies and to modify land management to improve carbon sequestration and retention. Here we discuss the…
Transferable offsets are a means of mitigating the adverse environmental impacts of resource developments. Based on insights from institutional economics, there are three elements that need to be in place for offsets to be effective: (1) property rights over the mitigating good can be defined…
Many studies have predicted, at a national scale, the economic viability of new forestry plantings to contribute to mitigation of greenhouse gas emissions in Australia's cleared agricultural lands. Such predictions are highly uncertain given: (i) differences in site quality, management…
Private land conservation is becoming a popular policy approach, given the constraints of increasing public protected areas, which include reduced availability of land for purchase, insufficient budgets for acquisition, and escalating management costs of small, isolated reserves. Conservation…
Shrub cover has increased in semi-arid regions worldwide. This change has generally been viewed as land degradation, due to shrub-induced declines in pastoral productivity. As a consequence, widespread management treatments to reduce shrub density have been applied in many pastoral areas. These…
Atmospheric correction of high spatial resolution (10–30 m pixel sizes) satellite imagery for use in large-area land-cover monitoring is difficult due to the lack of aerosol optical depth (AOD) estimates made coincident with image acquisition. We present a methodology to determine the upper and…
Numerous land-cover change detection techniques have been developed with varying opinions about their appropriateness and success. Decisions on the selection of the most suitable change detection method is often influenced by the study region landscape complexity and the type of data used for…
The majority of dairy farmers and processors in Australia and New Zealand are considered world class due to their ability to produce dairy products at a cost that is competitive on the world market without requirement for subsidy. International and domestic forces beyond the farm influence the…
The urban forest provides valuable ecosystem services for enhancing human well-being. Its structure and composition determine the quantity and quality of these services. There has been little research on the heterogeneity in structure and composition of urban forests in the Australasian region,…
Chemical and sediment losses from agricultural lands are threatening coastal marine and aquatic ecosystems in many parts of the world. This is an acute problem in Australia, where the condition of Great Barrier Reef (GBR) ecosystems is threatened by increased pollutant loads from agricultural…
The effects of agricultural practices on runoff water quality are a major concern worldwide, particularly where there is the potential to cause harm to aquatic ecosystems receiving the runoff. Cropping land has been identified as a major source of pollutants in the Fitzroy Basin, the largest…
