Malaria transmission and climate change in Australia.
Although endemic malaria was eradicated from Australia by 1981, the vectors remain and transmission from imported cases still occurs. Climate modelling shows that global warming will enlarge the potential range of the main vector, Anopheles farauti sensu stricto; by the year 2030 it could extend along the Queensland coast to Gladstone, 800 km south of its present limit. Vigilance and a dispassionate assessment of risk are needed to meet this challenge.
Abstract We examine the interrelationships in the global base metal markets over a 22 year period 1994–2016 using a variety of econometric methods. The results demonstrate the high intensity of both return and volatility spillovers across the selected markets. Furthermore, the degree of co-movements varies among time and frequencies. The study also contributes to the contagion literature since the results revealed the increase in co-movements after the financial crisis. Aluminium is found to be the driving force, with significant influence across all methodologies. The findings show that the behaviour of the non-ferrous metals is similar to other conventional asset classes, like equities and bonds, justifying the position that metals have become an investment class.
