Traders in commodity markets may have different time horizons. This paper uses a scale analysis to investigate heterogeneous trading in such markets. Estimates are presented for price correlations by scale and long memory in the volatility of commodity prices. Wavelet variance is estimated using...

A consistent methodology enabling the estimation of the economic losses associated with drought and the comparison of estimates between sites and across time has been elusive. In this paper, we develop an ecosystem service approach to fill this research gap. We apply this approach to analysis of...

Irrigation induced salinity is adversely affecting the agricultural industry and the environment in many countries around the world. Spatial location of irrigation enterprises has been identified as one important factor that needs to be taken into account by policies aimed at mitigating...

The recent drought in south-eastern Australia saw the lowest inflows on record in the Murray–Darling Basin in 2006. As reservoirs were drawn down water availability for irrigation was cut. In 2007–2008 and 2008–2009, irrigators received about one third of their pre-drought allocations....

This article evaluates irrigated agriculture sector response and resultant economic impacts of climate change for a part of the Murray Darling Basin in Australia. A water balance model is used to predict reduced basin inflows for mild, moderate and severe climate change scenarios involving 1, 2...

This paper reports on an analysis of irrigator water demand and profit changes across varying annual water availability, crop water requirements, and river salinity conditions for irrigation along the South Australian portion of the Lower Murray. The paper also investigates the validity of the...

Governments in Australia are purchasing water entitlements to secure water for environmental benefit, but entitlements generate an allocation profile that does not correspond fully to environmental flow requirements. Therefore, how environmental managers will operate to deliver small and...
