The high agricultural process of the Argentine humid pampas forces the intensification and relocation of cattle and dairy systems into subhumid and semiarid region to keep their competitiveness. In consequence, there is an increasing water demand scenario in these fragile areas in relation with...

Australian farmers have been warned of increases in wool auction price fluctuations since 2000 (Kingwell), yet 85% of producers continue to sell their wool on the highly volatile, open-cry auction system (Bolt 2004). It has been suggested that forward selling is one method available to farmers...

The use of protected areas as a fishery management tool has been suggested as a hedge against management failures and variation in harvests. A stochastic bioeconomic model of a two-species fishery will be used to test the performance of protected areas as a management tool in a fishery with...

In South Australia, commercial and recreational fishers compete to catch Snapper from a single stock. To distribute this resource appropriately, the widely accepted conceptual framework for optimizing the net benefits from resource allocation is applied. That is, by finding the point at which...

The production potential of OWB forage is evaluated under commercial rotational grazing management. The economic value of the forage is determined by the replacement value of the CP and TDN content. The optimal grazing period is determined where the MVP of grazing an additional day is equal to...

This paper studies the dynamic effects that the recent growth in supply of Distiller Dried Grains (DDGs), due to the ethanol production surge from corn consumption, has had in relation to other market feeds, specifically corn, grain sorghum and soybean meal. Prior to the U.S. ethanol surge, more...

Net annual costs for disposal by pumping to the Murray River, an on-farm evaporation basin, conjunctive use with surface water to irrigate dairy pasture, and undiluted irrigation of a salt tolerant grass were estimated and compared. Total conjunctive use (TCU) is the cheapest option below 10dS/m...
