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.

Experts Demand for Right Execution of Anti-Pollution Steps

There are policies and programmes to deal with air pollution

 Though nine Indian cities figure among the World Health Organisation’s 10 most polluted global destinations, lack of effective implementation of pollution control measures remains a major challenge, say experts.

The Narendra Modi government’s Pradhan Mantri Ujjwala Yojana, which ensures LPG connections to women from poor families, has helped lower indoor pollution. But vehicular emissions and stubble burning in the northern states remain major contributors to air pollution.

With polluted air raising health risks in a large part of India, the situation is critical to say the least and assumes significance as we get ready to celebrate the World Environment Day on Wednesday. The United Nation’s has set “air pollution” as the theme for this year’s celebrations.

“There are policies and programmes to deal with air pollution. But there are issues with their management,” said Anand Kumar, Associate Director (Environment and Climate Change) at IPE Global, a consultancy providing technical assistance and solutions for equitable development and sustainable growth in developing countries.

The government has dealt with vehicular emission through several policies, but stubble burning, which leads to smog and high level of pollutant in the national capital during winters, has not been looked at properly.

Last Diwali, in several parts of Delhi concentration of PM 2.5 exceeded 1,500 µg/m3, way above the “severe” category and could result in respiratory problems to even healthy people, said Kumar.

Environmentalist C.R. Babu stressed the need to raise public awareness. “Technology cannot help much in the fight against air pollution. The natural sinks (to absorb pollutant) have either filled or have been eliminated, while sources of pollution are increasing. How many vacuum cleaners or sprays can be used to remove dust? People’s participation is a must,” he said.

Babu suggested creation of green buffers as one way. “We need multiple patches of vegetation across the urban areas. Only a carpet of greenery can absorb dust and pollutant,” he said. (IANS)
