The Land and Water Management Plans (LWMPs) developed for the irrigation districts in the Murray region of NSW are said to be at the forefront of institutional innovation for integrated resource management. Farmers have been strongly involved both in the development of the Plans (for which...

Lessons learnt and progress achieved in a project seeking to catalyse establishment of a group, or common property, farming enterprise are reported in this article. The project concept grew from successful experiences of the farmers initiating the project in working together to address shared...

The whole farm financial effects of laser land forming were analysed using a two stage modelling procedure. In the first stage, linear programming models of representative Murrumbidgee Irrigation Area (MIA) rice farms were used to predict the profit-maximising activity mixes with and without...

Organic agriculture has emerged as an important contributor of ideas in the continuing Australian search for sustainable farming systems. Recognising this, choices arise over the need for government intervention to foster the development of organic approaches to agriculture. Even when the choice...

It is argued in this paper that static approaches to weed management, where the benefits and costs are only considered within a single season, are inappropriate for assessing the economic benefits of weed control technologies. There are carryover effects from weed management as weeds that escape...

Dryland salinity emergence is an important land degradation problem in Australia. Large areas of agricultural land where conventional crops and pastures are produced are at risk. The salinisation problem can be controlled by planting trees in conjunction with crops, but a disadvantage of growing...

When a weed invasion is discovered a decision has to be made as to whether to attempt to eradicate it, contain it or do nothing. Ideally, these decisions should be based on a complete benefit-cost analysis, but this is often not possible. A partial analysis, combining knowledge of the rate of...

The detectability of invasive organisms influences the costs and benefits of alternative control strategies, and the feasibility of eradicating an infestation. Search theory offers a mathematically rigorous framework for defining and measuring detectability, taking account of searcher ability,...
