Anyone who knows Baby Boomers knows this generation is not going to go off quietly into old age. Combine that with the fact that Australians are living longer, and it is essential we unlock the benefits of integrating plants and living infrastructure systems into our aged care facilities.
Sustainability and Water August 12, Water tables all over the world are falling, as "world water demand has tripled over the last" 50 years.
When these aquifers are depleted, food production worldwide will fall.
Water tables all over the world are falling, as "world water demand has tripled over the last" 50 years. These aquifers are inexorably being depleted in ways that are "largely invisible, historically recent, and growing fast", and "the near-simultaneous depletion of aquifers means that cutbacks in grain harvests will The water tables of China, India, Pakistan, Mexico and Yemen are dropping by 1 to 3 meters per year, as are those of the US, especially in the southern Great Plains where "thousands of farms Since one ton of grain requires tons of water, this water deficit will cross international borders in the form of increasing grain prices worldwide.
Grain shortages are likely to occur soon in China, where the grain harvest is shrinking as a combined result of "aquifer depletion, the diversion of irrigation water to cities and lower grain support prices".
This could "destabilize world grain markets. Raising irrigation efficiency and recycling urban wastewater is being practiced with some success in some countries. Local Action For Global Challenge.
Even where there is availability of water, conveying it to communities that need it becomes an issue. Provision of drinking water is expensive and difficult. Unsafe water sources have accounted for preventable diseases in rural communities.
In many countries water is shared with cattle, which has serious implications on human health. Already there are about million people in 29 countries, who are facing water shortages, and chasing fewer sources of fresh water.
The water crisis has also affected health matters of many people and at the moment, it is estimated that half the hospital beds in the world are being occupied by patients who are suffering from water related illnesses.
About million people are infected with dysentery, 20 million of whom are seriously ill. The average distance undertaken by African and Asian women and children to gain access to water is approximately six kilometres.
Agriculture also has effect on water since intensive cultivation of crops causes chemicals from fertilizers and pesticides to trickle down into the groundwater. The routine application of fertilizers and pesticides are being recognized as water pollution.
Waste water from manufacturing as well as chemical processes in industries have also contributed to water pollution. An estimated 14, to 30, most being children, die everyday from avoidable water related diseases.
It is important that governments develop cost effective methods to ensure safe drinking water for everyone. In order to move towards sustainability, industries must be assured of having adequate water supply but must see that water use in industrial processes is handled efficiently.
Policy makers need to allocate water to satisfy environmental demands. Water managers could improve the sustainability and productivity of irrigated systems, by considering groundwater availability when allocating surface water for irrigation.
By January, cities statewide are supposed to have regulations that limit the amount of water used for landscape irrigation in future commercial and residential projects.Ageing of Australia’s Population Peter McDonald and Rebecca Kippen May Professor Peter McDonald is Head of the Demography Program in the Research School of Social Sciences of the Australian National University.
Ageing is the most dramatic change that will occur to Australia’s population, particularly over the next 50 years (Luszcz et al., ). Population of Australia is ageing because of the combined effects of increasing longevity and.
This report is the fifth in the series World Population Ageing. The first report was released in in The first report was released in in conjunction with the Second World Assembly on Ageing. Introduction. In Australia, there has been a demographic shift in the overall age of the population and now it is said to be ageing.
This is not just happening in Australia alone, but in other developed countries such as Japan, Canada and France, which are also experiencing a shift in the age of its population. The age pension should be indexed to life expectancy, the productivity commission has suggested, as an ageing population combined with a slowdown in growth is set to put pressure on federal.
The demography of Australia covers basic statistics, most populous cities, ethnicity and religion. The population of Australia is estimated to be 25,, as of 15 November Australia is the 52nd most populous country in the world and the most populous Oceanian country.
Its population is concentrated mainly in urban areas and is expected to exceed 28 million by
