India is among the world’s major hotspots which has seen a serious decline in the availability of freshwater due to overuse of water resources, reveals a new study that combined an array of NASA satellite observations of Earth with data on human activities.
The study, published in the journal Nature, found that Earth’s wetland areas are getting wetter and dry areas are getting drier due to a variety of factors, including human water management, climate change and natural cycles.
Areas in northern and eastern India, the Middle East, Australia and the US state of California are among the major areas where overuse of water resources has led to a serious decline in the availability of freshwater, the Guardian reported this week citing the study.
Without corrective actions by the governments to preserve water, the situation is likely to worsen in these areas, it added.
The first-of-its-kind study used 14 years of observations from the US/German-led Gravity Recovery and Climate Experiment (GRACE) spacecraft mission to track global trends in freshwater in 34 regions around the world.
“This is the first time that we’ve used observations from multiple satellites in a thorough assessment of how freshwater availability is changing everywhere on Earth,” said Matt Rodell of NASA’s Goddard Space Flight Center in Greenbelt, Maryland,
“A key goal was to distinguish shifts in terrestrial water storage caused by natural variability – wet periods and dry periods associated with El Nino and La Nina, for example – from trends related to climate change or human impacts, like pumping groundwater out of an aquifer faster than it is replenished,” Rodell added.
Freshwater is found in lakes, rivers, soil, snow, groundwater and ice. Freshwater loss from the ice sheets at the poles – attributed to climate change – has implications for sea level rise.
On land, freshwater is one of the most essential of Earth’s resources, for drinking water and agriculture.
The researchers found that while some regions’ water supplies are relatively stable, others experienced increases or decreases.
“What we are witnessing is major hydrologic change,” said co-author Jay Famiglietti of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.
“We see a distinctive pattern of the wet land areas of the world getting wetter – those are the high latitudes and the tropics – and the dry areas in between getting dryer. Embedded within the dry areas we see multiple hotspots resulting from groundwater depletion,” Famiglietti warned.
One of the biggest causes of groundwater depletion across the board was agriculture, which can be complicated by natural cycles as seen in California, Famiglietti said.
Decreases in freshwater caused by the severe drought from 2007 to 2015 were compounded by groundwater withdrawals to support the farms in the state’s Central Valley.
Southwestern California lost four gigatons of freshwater per year during the same period. A gigaton of water is the equivalent of the mass of water in 400,000 Olympic swimming pools.
Downward trends in freshwater seen in Saudi Arabia also reflect agricultural pressures, the study said.
From 2002 to 2016, the region lost 6.1 gigatons per year of stored groundwater.
The study also showed that previously undocumented water declines occurred in northwestern China’s Xin Jiang province.
Famiglietti noted that while water loss in some regions, like the melting ice sheets and alpine glaciers, is clearly driven by warming climate, it will require more time and data to determine the driving forces behind other patterns of freshwater change.
The GRACE satellite observations alone could not tell the researchers what was causing the apparent trends.
“We examined information on precipitation, agriculture and groundwater pumping to find a possible explanation for the trends estimated from GRACE,” said co-author Hiroko Beaudoing of Goddard and the University of Maryland in College Park. (IANS)

Readout excerpts from the interview with Susovan Sonu Roy.
Mahyah Binti Idris: Before we begin with this interview, would you like to tell us something about yourself?
SS Roy: So, basically, I am an actor from Kolkata, and I have worked in Bengali TV Serials, and I started my career in the entertainment industry as a western dancer. When I was just five years old, I lost my father in a car accident. Despite my difficult upbringing, my mother never wavered in her commitment of achieving the goals I set for myself.
Mahyah Binti Idris: Despite your mother's wishes, what was the inspiration that made you decide to pursue a career in acting/dancing instead of singing?
SS Roy: I am a firm believer of the fact that inspiration comes from within, and positivity is essential. Things go your way when you're upbeat and optimistic. I enjoy the work I do, and once I started my career in the entertainment industry, there was no turning back, I kept acquiring one project after another. I have always wanted to be an actor, and I am happy that I found my inspiration from within.
Mahyah Binti Idris: You played a negative character in 'Kora Pakhi' for several months. What kind of impact did it have on your professional life after opting for such a role?
SS Roy: I am pretty comfortable in opting for any kind of role I am offered because I believe acting is acting, whether it is a big role, a minor role, a negative or a positive role. I take inspiration from the likes of Shahrukh Khan, Akshay Kumar, Mithun Chakraborty and John Abraham.
Mahyah Binti Idris: Nowadays, cyberbullying and trolling are getting more frequent. How do you handle trolls or deal with criticism?
SS Roy: Trolls exist just to cause others distress. I ignore all the negativity and don't let it affect me in any way. If anyone lets the negative comments get into their head, they will find it difficult to do anything, as negativity hinders pursuing dreams.
Mahyah Binti Idris: What, in your opinion, is more crucial to long-term success in the field of acting, additional projects or formal training?
SS Roy: Indeed, training about the various techniques used in acting is essential, and once you get into the role, everything comes out naturally but that doesn’t mean one should stop training to become better day by day, training and trying to improve your skills is very important.
Mahyah Binti Idris: Where do you see yourself in a few years, and what projects do you have on your bucket list?
SS Roy: I auditioned for a movie that will feature Kajal Aggarwal in the lead. My ultimate goal is to crack a role in Bollywood. I want to gain as much experience as possible in serials and movies.
Mugdha Dubey: What is the difference in the challenges one faces while struggling to gain a role in regional cinema and Bollywood?
SS Roy: The difference in struggle is huge; it is pretty challenging to get a role in Bollywood. But I believe that experience matters and gives you an edge over others because you are already aware of some techniques used in acting and won't commit the mistakes a fresher does. I got the chance to audition for a movie with the lead as Kajal Agarwal because of my experience.
Mugdha Dubey: Have you ever witnessed nepotism firsthand, or did you ever feel that nepotism is prevalent in the Kolkata film industry?
SS Roy: Nothing can stop you if you put in the effort and stay true to your ambitions. But, one cannot ignore the fact that nepotism is everywhere, be it Bollywood or Tollywood. The acquaintances of artists get easily recognized but that shouldn’t demotivate aspiring actors because your hard work matters and if you keep working hard in the right direction, you will surely get recognized.
Mugdha Dubey: What message or tips would you like to convey to today's youngsters and those who aspire to become actors?
SS Roy: I would encourage the young generation to stand up for what they believe in and make the world a better place for future generations by following your passions and utilizing your inborn talents and abilities. If they aspire to become actors, I would like to tell them that mere luck will not be sufficient to become an actor; the struggle is real. You need to work very hard and train yourself to become an actor. Your success and failure depend on what you do, and the type of content you can produce, and one should always try to improve themselves.

NASA will pay up to $1 million to people who can come up with innovative and sustainable food production ideas to feed astronauts in space, as the US space agency prepares to send astronauts further into the cosmos than ever before. Giving future explorers the technology to produce nutritious, tasty, and satisfying meals on long-duration space missions will give them the energy required to uncover the great unknown. In coordination with the Canadian Space Agency, NASA has launched the 'Deep Space Food Challenge' that calls on teams to design, build, and demonstrate prototypes of food production technologies that provide tangible nutritional products -- or food.

"Feeding astronauts over long periods within the constraints of space travel will require innovative solutions," said Jim Reuter, associate administrator for NASA's Space Technology Mission Directorate in Washington, DC. "Pushing the boundaries of food technology will keep future explorers healthy and could even help feed people here at home," he said in a statement. Over time, food loses its nutritional value. That means for a multi-year mission to Mars, bringing along pre-packaged food will not meet all the needs for maintaining astronaut health.

In October 2021, Phase 1 of the challenge culminated as NASA awarded 18 teams a total of $450,000 for their concepts for innovative food production technology that produces safe, acceptable, palatable, nutritious food products. NASA now invites both new and existing teams to enter Phase 2 for a prize purse up to $1 million. "Everything needed to store, prepare and deliver food to the crew, including production, processing, transport, consumption, and disposal of waste should be considered," said NASA. Proposed technologies such as plant growth systems, manufactured food products, and ready-to-eat solutions combined could provide the future crews with a variety of options that would provide the needed daily nutrition, it added.

People suffering from depression are more likely to believe vaccine-related misinformation, according to a new study. The study found that people with moderate or greater symptoms of depression were more likely to believe at least 1 of 4 false statements about Covid-19 vaccines.
Those who believed the statements to be true were half as likely to be vaccinated, the study, published in the Journal of the American Medical Association, indicated. 'It is clear the pandemic has taken a heavy toll on the mental health of Americans, especially young people," said researcher Katherine Ognyanova from Rutgers University, the US.

According to the National Center for Health Statistics, approximately one-quarter of adults in the US have consistently reported moderate or greater depressive symptoms during the Covid-19 pandemic. The findings suggest that people suffering from depression may be at a higher risk of Covid-19, highlighting the need to address mental health disorders.
For the study, the team used data from the research group The Covid States Project, which conducted surveys approximately once every six weeks since April 2020. The researchers analysed data from 15,464 adults in the US and the participants were asked to rate vaccine-related misinformation as accurate (statement is true), inaccurate (statement is not true) or not sure.

The four statements of misinformation included "The Covid-19 vaccines will alter people's DNA", "The vaccines contain microchips that could track people", "The vaccines contain the lung tissue of aborted fetuses", and "The -19 vaccines can cause infertility, making it more difficult to get pregnant". The survey participants completed a health questionnaire to measure major depressive symptoms over two weeks. (IANS/ MBI)
