Dryland farming and its profitability is directly affected by the amount and timing of rainfall that influence and consequently impacts on pasture and crop yields. Yet rainfall is not the sole determinant of farm enterprise profitability; prices of farm inputs and commodities produced also...

Choosing the appropriate reservoir water management strategy can be difficult when the water has multiple uses. This study examines this problem for reservoir managers where water use involves irrigation and fisheries. A stochastic dynamic programming (SDP) model is developed to facilitate...

This region has experienced pronounced climate variability and volatile commodity prices since the late 1990s. Relationships between productivity and profitability are explored...</p>

Tedera (Bituminaria bituminosa C.H. Stirt var. albomarginata) is a drought tolerant perennial legume originating in the Canary Islands. This study evaluates the potential role and value of tedera in dryland mixed crop and sheep production systems in southern Australia. Regional variants of the...

A framework for interpreting profit–environmental trade-offs in pastoral agriculture is introduced, drawing on the concepts of economic and environmental efficiency. The approach provides insights into appropriate policy mechanisms to address the environmental footprint of agricultural...

<Para ID="Par1">Dietary Guidelines for many countries recommend that people should eat ‘nutrient dense’ foods, which are foods with a high nutrient to energy ratio; and that people should limit their intake of saturated fat, added salt or added sugar. In addition, consumers and environmentalists...</para>

A model of investment in crop sowing machinery is applied to wheat production under current and projected climatic conditions at several locations in south-western Australia. The model includes yield responses to time of sowing at each location given current and projected climatic conditions....
