India lost 20 billion unbelievable 75 billion hours of labor due to the waves of mountains that cause outdoor work to be extremely difficult for lakhs, says a new research that assesses the vulnerability of nations to a growing temperature.
Indian loss accounts for roughly 49% of the world's workforce and is equivalent to nearly 39 million people who did not work at all in 2017, representing 7% of the Indian working population.
Rising temperatures pose a risk in the field of occupational health, and as temperatures rise regularly above physiological limits, permanent work becomes more difficult or impossible.
In 2017, 153 billion hours of work was lost due to exposure to heat, an increase of 62 billion hours over losses in 2000. Most of the losses occurred in India, Southeast Asia, sub-Saharan Africa and South America are already vulnerable.
Approximately 80% of these losses were in the agriculture sector (122 billion hours lost), 17.5% in the industry (27 billion) and 2.5% in the services sector (4 billion), according to a study published in the November 28 issue of the magazine Lancet.
The conclusions are published days before the start of the UN climate summit in Poland, where the world has to finalize a book of rules to meet the emission reduction targets set in Paris three years ago.
"The vulnerability of extreme temperatures has risen steadily since 1990, leading to huge losses for national economies and household budgets," said Joachim Rocklöv, a professor at Umea University in Sweden and one of the authors of the research paper.
"The most vulnerable to heat-related hazards are elderly people (especially in urban areas) who weaken heat protection and handy workers exposed to a hot environment such as agriculture, construction and manufacturing," said Nick Watts, executive director of Lancet Countdown, multidisciplinary research collaboration between academic centers around the world that tracks the relationship between climate change and health.
"People with pre-existing medical conditions such as neurological and psychiatric illness, heart disease, lung disease, kidney disease and diabetes are at risk of heat," said Watts, a colleague at University College London, Institute for Global Health DH.
In the past, Indian meteorologists have warned that waves of heat will become more frequent and more frequent in the future. In 2015, more than 2,000 people in India died of hot waves.
Worldwide, 157 million vulnerable people were exposed to global warming globally in 2017, and 153 billion hours of work were lost during the heat exposure.
