Australia since 1970 - less water and increasing droughts

Time-based data evaluation and mapping by the Bureau of Meteorology starkly demonstrates the historical pattern of less rainfall over the Eastern half of the Australian continent which has occurred over the past 40 years. The Eastern half of the continent, comprising the states of  Victoria, New South Wales and Queensland, produces most of the agricultural outputs whereas the Western half of the continent is semi-arid, arid to desert and cannot support food production. The impact of less rainfall will be continue to be an acute problem and one which requires faster adaptation than is currently the case.
