The production of meat from sheep and goats in Australia occurs almost entirely at pasture in zones known as the semi-arid pastoral zone, the wheat-sheep zone (where sheep and crops form an agricultural rotation system) and the high rainfall zone. Each zone has particular factors which affect the human health hazards associated with sheep and goat meat and the opportunities for prevention. The ...

This paper hypothesizes that Chilean firms had a competitive advantage in operating businesses in other Latin American countries because of their knowledge of business strategy during economic reform. This hypothesis is explained through case studies of Provida, a Chilean pension fund, and Endesa, a Chilean electricity generator, and then tested empirically using data on foreign affiliates of C...

The development of arid zone geomorphology has progressed over the past century from ground-level observations of a limited number of locations through the field traverse mapping of sizeable arid areas to a broad-scale overview of global desert regions assisted by aerial photography and satellite imagery. Extraterrestrial investigations of planetary surfaces and landforms have proceeded in exac...

In 1990–1994, over nine survey periods, we recorded a total of 684 breeding attempts deriving from 51 species in landbird community arid north-western New South Wales. We investigated whether effort was related to regular seasonal patterns (spring vs winter) or irregular fluctuations rainfall (pre-drought drought isolated thunderstorm above-average post-drought). The and number the study area w...

Available fresh water resources are subjected to an ever-increasing pressure due to extensive agricultural water demand for irrigated lands. A long-term perspective in shortage of fresh water resources, especially in arid and semi-arid area, highlights an urgent solution for innovative irrigation strategy and agricultural water management. This paper is a review on the wide applications of the ...
