Perth Relies on Recycled Water to Cope up with Climate Change in Australia

Perth is a city of two million people, and Clare Lugar from Western Australia's Water Corporation said it has had to get used to climatic changes

As drought-hit towns across New South Wales and Queensland edge closer to completely running out of water, federal and state governments in Australia are trying to come up with ways to guarantee supplies into the future. But on the other side of the continent, the city of Perth is leagues ahead in its water efficiency following a long-term decline in rainfall. Part of its survival plan relies on recycled water from toilets, a move that many consumers elsewhere still consider to be unpalatable.

Since 2017, residents in the Western Australian city of Perth have been drinking water recycled from sewage. It is filtered using a process called reverse osmosis, which is similar to forcing water through a giant sponge. It is then disinfected with ultra-violet light at a treatment plant, pumped into natural aquifers, and extracted.

Perth is a city of two million people, and Clare Lugar from Western Australia’s Water Corporation said it has had to get used to climatic changes. “We know from the mid-70s onwards Perth’s rainfall has been declining by about 20 percent, and that has had a huge impact on our water sources that are dependent on the climate.”

Lugar said convincing residents of the benefits of drinking recycled sewage did take time. “So, it is only a small percentage of the water that comes into the plant is actually from our toilets. But getting over that perception, that kind of image you might be drinking the water that you flushing down the toilet – that was probably one of our big challenges initially,” said Lugar.

Two desalination plants supply about half of Perth’s water. Aquifers are also crucial, but recycling produces only two percent of the total. But that figure is soon expected to rise. Ian Wright, an expert in environmental science at Western Sydney University, believes other parts of Australia should embrace recycling.

“In Sydney that is probably 150 liters per day per person of waste water that is completely wasted, and, yes, we have the availability of desalination on the coast, but Canberra does not have desalination and then the poor drought-stricken towns like Tamworth and Dubbo, and Broken Hill, they could really, really use that now,” he said.

Australia is the world’s driest inhabited continent. Water is precious, and, in many places, scarce. More than 95 percent of New South Wales, Australia’s most populous state, is officially in drought, and the next three months are forecast to be drier than average. (VOA)

Escalating Consequences of Climate Change Hit Countries Globally

India was ranked fifth vulnerable globally

The escalating consequences of Climate change are now hitting both rich and poor countries, a report published on Wednesday said. India was ranked fifth vulnerable globally.

The Climate Risk Index 2020, an annual report by Germanwatch, ranks countries according to their vulnerability to extreme weather events.

It was released in the Spanish capital on the sidelines of the 25th Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) or COP25 that is being held in the backdrop of climate impact biting globally.

According to the report, India has also been badly affected, ranking fifth in the overall global vulnerability index in 2018, ranked first in terms of fatalities and second in the world in terms of losses in millions of dollars.

India’s overall ranking has drastically fallen from 14th in 2017, to fifth in 2018.

The report shows that extreme weather, linked with climate change, is affecting not only the poorer countries like Myanmar and Haiti, but also some of the world’s richest countries.

Japan is the worst-hit country in 2018, while Germany and Canada were both also in the ‘bottom 10’ i.e. the most affected.

The results reflect the increasing damage caused by heatwaves, which scientists have found are being worsened by climate change.

To explain this drastic fall in ranking in a year, David Eckstein, Policy Advisor (Climate Finance and Investment) with Germanwatch said: “India’s high rank is due to severe rainfall, followed by heavy flooding and landslides that killed over 1,000 people.”

The state of Kerala was especially impacted. The floods were described as the worst in the last 100 years.

According to Eckstein, India was struck by two cyclones in October and November 2018 that also nearly killed 1,000 people. Last but not least, India also suffered from extreme heat. While the human death toll was kept considerably low due to public measures, the economic damage was quite severe.

Other countries ranking in the bottom 20 in the overall climate risk categories are the US at 12th, Vietnam at sixth, Bangladesh at seventh and France at 15th.

The report also points to the importance of negotiations at COP25. As climate impacts begin to result in permanent loss and damage across the world, there is still no specific UN climate finance facility to reimburse the loss of land, culture and human lives.

So far, the industrialised countries have refused to even negotiate it.

But at COP25, for the first time, financial support for climate-related loss and damage is high on the agenda.

For the poorest and most vulnerable countries, this climate summit is, therefore, of the utmost importance. They demand that states agree a deal to support those who are suffering, or at least acknowledge the necessity, with a pathway towards real help.

Otherwise the poorest countries will continue to rely on loans to cope with the consequences of climate change, which means they are threatened with excessive debts, undermining often already vulnerable economies.

In the talks that will last till December 13, India has been ambitious in its actions.

It has emphasised that developed countries should take the lead in undertaking ambitious actions and fulfil their climate finance commitments of mobilising $100 billion per annum by 2020 and progressively and substantially scale up their financial support to inform parties for future action through Nationally Determined Contributions (NDCs).

India is also stressing upon the need for fulfilling the pre-2020 commitments by developed countries, and that pre-2020 implementation gaps should not present an additional burden to developing countries in the post-2020 period.

The Indian delegation will be led by Environment Minister Prakash Javadekar, who is attending the summit from December 9. (IANS)
