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.
