Environmental Bad Effect on Human Labour Productivity of Dhaka
Environmental Bad Effect: Due to Extreme Heat Dhaka, Bangladesh is losing about $6 billion every year of human labour productivity.
Now-a-days environmental issue is the vital issue in the world. And Bangladesh is now gradually getting more environmental affect than other countries. Dhaka, The major municipality of Bangladesh is losing about $ 6 billion worth of labour productivity each time due to heat stress from extreme temperatures, said a study published history.
This amounts up to 8 percent of the periodic labour affair in Dhaka, said the study published by the Adrienne Arsht- Rockefeller Foundation Resilience Center, a common action of The Rockefeller Foundation and philanthropist Adrienne Arsht.
The study compared 12 megalopolises across the globe and set up that in Dhaka heat impairs labour productivity further than any other megacity.
The other megalopolises studied include New Delhi, Athens, Buenos Aires, Freetown, London, Los Angeles, Miami, Monterrey, Santiago and Sydney.
The study named" Hot megalopolises, astounded husbandry Impacts of Extreme Heat on Global megalopolises" said unless measures were taken to reduce global warming, the loss will rise to 10 percent by 2050.
This is the topmost share of losses of any megacity in this study, it added." While others similar as Abu Dhabi and Bangkok are more exposed to heat stress, Dhaka is suddenly vulnerable to its goods, due to its labour-ferocious frugality and low rate of active cooling," said the report.
As per former record high temperatures and moisture of between 60 and 80 percent in Dhaka, climate change is set to make goods mainly worse.
Because of the unbounded warming, sectors similar as manufacturing loses$1.5 billion while logistics loses$1.8 billion monthly.
The report states that in Dhaka, for the 10 hottest days of a typical time, the apparent temperature by considering both heat and moisture is hotter than the mortal body.
In 2020, Dhaka endured36.5 days in which the 24- hour average temperature was further than28.8 degree Celsius. By 2050, this could rise to69.8 days.
The face of roads can presently reach up to 60 degree Celsius, set up the report. Majorly large and wide hotspots within the megacity are further than 10 degree Celsius advanced than the girding country. In the report has mentioned that The heat impacts the poor disproportionately. The major worker productivity which is related profitable losses from the heat are felt by those least suitable to bear them. In sectors similar as garment manufacturing, transport, and retail trade, where stipend can be lower than average, losses formerly amount to around 10 percent of income.
Losses in manufacturing are likely to be particularly high in sectors similar as garment manufacturing or slipup timber, where propinquity to ministry or ranges increases the temperature to which workers are exposed, said the report.
It said that heat is concentrated in some of the megacity's poorest areas.
In Kamranggirchar, southern an area of Dhaka City containing a high attention of informal agreements with wide use of corrugated iron distance roofing, temperatures are generally 12 degree Celsius advanced than Dhaka's surroundings.
similar temperatures lead to health pitfalls, it added.
Presently The world is burning. Unfortunately, that is not an magnification. Climate- driven heat is changing the way we live and work, reflected the report truly precisely.
Ashraf Dewan, a professor at School of Earth and Planetary lores, Curtin University, Australia, had ahead studied collaborative heat islets and how the temperature of Dhaka has risen over the decades. He said collaborative heat islets are places whose temperature is hotter than the girding areas. Temperature is sporadically felt else in different places of Dhaka City. And also he explained that the poorest areas are hotter because of lack of verdure and the use of corrugated iron wastes. These trap heat during the day, and don't radiate heat presto enough at night. Since these areas are girdled by high- rise structures that don't grease wind flux, the air gets trapped.
Water bodies used to cool down the megacity. But we do not have water bodies presently. In addition, the reliance on air conditioners lead to heat being allocated into the girding air." Main focus point is glass structures aggravate collaborative heat islets – they let in heat and light during the day but they need further air conditioners for cooling." ProfessorMr. Ashraf Dewan said that the easiest and cost-effective result is to plant further trees – they don't let the air temperature rise.
Finally, I want to say that we should take care our environment like our child. We should keep the world safe for our next generation.
