Economic losses and costs associated with weeds in dryland cotton production are important, both for growers and for industry bodies when making decisions about research priorities and research and development funding. A survey was conducted to provide information on weed types, control...

Implementation of Council of Australian Governments (COAG) and State based water reform initiatives are likely to create significant structural adjustment pressures in irrigation areas throughout the Murray Darling Basin. There are concerns about the adequacy of short run models in both...

In recent years, there has been both more widespread evidence of the declining health of many of NSW’s rivers as a result of increased irrigation extractions and increasing community concerns about environmental issues. This has led to a greater focus on the need to re-balance in-stream and...

Invasive animal pests inflict many kinds of damage on the environment, and threaten native fauna and flora. We attempt to value the benefits from the extra biodiversity that is protected if these threats were removed. The NSW Rural Lands Protection Board is a major agency that undertakes pest...

Herbicide labels recommend sufficiently large doses to achieve high efficacy of weed control under a range of environmental conditions. While users may not apply doses greater than recommended they may apply less, but do so without quantitative guidance. This paper explores long-run biological...

Currently, some 90 million hectares of agricultural land in Australia is considered to be acidic and around 35 million hectares are considered to be highly acidic which is both a serious agricultural and environmental problem. The nature,...

Economic evaluations of the benefits of integrated weed management often only consider the benefits of management in the crop phase, and ignore the impact of rotational options. In particular, non-crop phases such as annual and perennial pasture phases can have a substantial impact upon weed...

Invasions by non-indigenous plant species pose serious economic threats to Australian agricultural industries. When an invasion is discovered a decision has to be made as to whether to attempt to eradicate it, contain it or do nothing. These decisions should be based on long term benefits and...
