Asian countries are to face severe water shortages by 2050, if the situation continues the same. The environmental, demographic and economic trends remain unchanged as it is 2050. If the climatic conditions change day by day which lead to water shortage by 2050.
“It’s not just a climate change issue. “We simply cannot ignore that economic and population growth in society can have a very strong influence on our demand for resources and how we manage them. And climate, on top of that, can lead to substantial magnifications to those stresses.” co-author Adam Schlosser emphasizes.
One billion people to face severe water shortages by 2050:
There are many reasons for this water shortage like climatic changes, environmental stress and some other factors like the best access to the precious natural resources, says the reports published in Journal PLOS One. All these factors lead to water shortage in coming days.
By observing the MIT and Integrated Global Systems Model (IGSM) we better understand the population growth and economic development and its interaction with climatic changes that which leads to water stress.
“This model gave us a unique ability to tease out the human and environmental factors leading to water shortages and to assess their relative significance”, Schlosser says.
“For China, it looks like industrial growth has the greatest impact as people get wealthier. “In India, population growth has a huge effect. It varies by region.” lead author Charle Fant explains
The IGSM is based on estimation of population growth, economic expansion, climate and carbon emissions because of human activity. Scientists looked at different possible scenarios for 2050 in many asain countries that include India and China in its studies.
Scientists called one of their scenarios proposed by them `Just Growth` , as they held climatic conditions constant and only exposed the effects of economic and population growth.
