If we keep wasting water at the current rate, there will be a severe shortage of water by 2050, a study has suggested.

According to a research by  Anthony Parolari from Duke University, the global demand of water will  surpass the supply if the population keeps burgeoning in the current manner by 2050. The water levels are diminishing and the consumption trend is a worrying site.

“But if population growth trends continue, per-capita water use will have to decline even more sharply for there to be enough water to meet demand,” said researcher Anthony Parolari from Duke University.

The researchers used what is called a delayed-feedback mathematical model to analyze historic data to help project future trends.

“The world population is projected to escalate up to 96 billion till 2050. What strains us is how would we comply to the growing needs of every new born? How much more water can we supply? We might be reaching an alarming state where the efficiency measures are no longer sufficient and water scarcity either impacts population growth or pushes us to find new water supplies,” researches said.

“For every new person who is born, how much more water can we supply? The model suggests we may reach a tipping point where efficiency measures are no longer sufficient and water scarcity either impacts population growth or pushes us to find new water supplies,” Parolari noted.

Water recycling, and finding new and better ways to remove salt from seawater, are among the more likely technological advances that could help alleviate or avoid future water shortages.

Once Water-Starved, Chennai’s Cantonment Area Now Boast of 13 Brimful Water Bodies

Once water-starved, Chennai’s Cantonment area and military station now boast of 13 brimful water bodies and recycling plants, and also generate their own electricity. Inspired by the innovation, the Ministry of Defence has directed its Estate Wing to implement the development work across all defence establishments.

The ministry has suggested Directorate General, Defence Estates (DGDE), an inter-services organisation of the ministry which directly controls the cantonment administration, to replicate the Chennai Cantonment area development model.

Water bodies — 13 in all– are revived and a water recycling mechanism was put in place at both Cantonment Board St. Thomas Mount cum Pallavaram and Military Station, where there was an acute shortage of water in 2018.

A senior Indian Defence Estates Service (IDES) officer said that additional storage space for two-crore-litre water was created. “Further, because of recycling plant, 2 lakh liters of treated water is used in these areas per day,” the officer said.

The board also created a waste management system where door-to-door collection of garbage is being carried out and then segregated into bio degradable and non-biodegradable. It is then treated in a bio-compost pit. Thereafter, biodegradable waste is put in centralised processing wind row system and then manure is created and made available for sale.

The board revived a green zone with around 2,000 plantations, set up solar power plants and a sewage treatment plant.

The solar power infrastructure set up in a year had generated electricity worth Rs 1 crore which is distributed within the cantonment areas.

Interestingly, the board has created a separate dumping zone for plastic bags. The board came up with an innovative idea of retrieval of ration milk and meat poly packets from consumers. It formalised collection and disposal, prevented littering and reaped financial benefits.

A senior Indian Army officer said the innovative idea was of Lieutenant General S.T. Upasani, who was the General Officer Commanding (GOC) of Dakshin Bharat Area. Lt Gen Upasani recently took charge as Director General of Information System, the crucial post in Indian Army which was lying vacant for the last two months.

Further, the board carried out campaign to revive green zone and planted 2,022 trees with 98 per cent survivability.

This development model is set to be replicated at 61 cantonments areas across the country that had been notified under the Cantonments Act, 1924, which was succeeded by the Cantonments Act, 2006. There are 62 cantonment areas. The overall municipal administration is managed by the cantonment boards, which are democratic bodies.

The ex officio president of the board is the station commander and the Chief Executive Officer, who is also the Member-Secretary of the Board, is an officer of the IDES or Directorate General, Defence Estates (DGDE). (IANS)
