Over 2,000 deaths from lightning from 2011-20

Lightning strikes have turned into the deadliest natural disaster in Bangladesh, claiming over 200 lives every year due to the loss of natural defences and a lack of precautionary measures, experts have said.

They blamed deforestation, worsening air pollution and global warming, climate variability, and the growing use of mobile and other technological devices for the increase in the frequency of lightning strikes.

According to the Ministry of Disaster Management and Relief, a total 2,164 people died in lightning strikes in the country from 2011 to 2020. At least 216 people die every year on average in lightning strikes, more than by floods, cyclones, and other natural calamities.

Experts said about 70% of the lightning strikes occur between April and June, and they advised everyone to move with caution during this time.

Farmers the worst victims

When contacted, Md Rashim Molla, secretary general of Save the Society and Thunderstorm Awareness Forum, said a recent study found that at least 177 people, including 122 farmers, were killed and 47 others injured by lightning strikes across the country between March 31 and June 7.

The casualties were higher in Sunamganj, Netrokona, Kishoreganj and Gaibandha districts over the last one and a half months.  “Most of those killed by lightning strikes were working in open fields or fishing.  About 90% of the victims were men.”

He said lightning has now turned into the deadliest natural disaster in the country. “The death toll from lightning strikes is much higher than that of cyclones, tidal surges, landslides and floods.”

Rashim said people in rural areas, croplands, playgrounds, and open spaces are mainly falling victim to lightning strikes.

Causes of lightning strikes

Prof Ainun Nishat, a noted climate change researcher, said it seems the frequency of lightning strikes has increased in Bangladesh due to the rise in temperature caused by climate change. “But data relating to lightning strikes is not collected scientifically in our country. We should take steps for collecting solid data and carry out scientific studies in this regard.”

He said the overall temperature in the world is growing gradually. “The growing temperature due to climate change is causing more water evaporation from the land and ocean. It’s increasing black clouds with potential lightning storms."

Rashim Molla said climate change, deforestation, increases in rain clouds, random set-up of mobile towers and increase in temperature across the globe can be the main factors behind the unusual rise in thunderstorms.

Besides, Rashim said, a one-degree rise in temperature can cause the chances of thunderstorms to rise by 10%.

Gawher Nayeem Wahra, member secretary of Disaster Forum, said the main reason behind the increase in lightning strikes is the lack of trees. “Thunderbolts attack the tallest thing in a field or open space without trees.

“People's knowledge on earthing is low. Houses that had earthing are gone now along with trees,” he observed.

Gawher said many people die on the spot after being hit by lightning strikes while many others are injured and slowly die as there is no treatment for lightning burns.

What is the solution?

Ainun Nishat said hotspots for the lightning strikes should be identified properly through scientific studies and effective steps need to be taken to protect people there.  “People should be made aware that they shouldn’t be in the open field when back clouds gather in the sky.”

He said the government has taken a steps to plant palm trees to lessen the casualties, but it takes at least 20 years to raise such a tree to the necessary height.

The expert also said the Disaster Management Bureau has taken a step to install poles or lightning arresters in fields across the country. 

“This is a good initiative,” he added.

Gawher Nayeem said the Disaster Management Bureau has focused on trees alongside roads, but steps are needed to protect those who work in the fields.

He said the plantation of more trees is one of the solutions to save people from lightning strikes. “Lightning arresters should be set up so that they can catch the thunderbolts in the absence of trees. Many electric poles can be turned into arresters easily. Nepal has achieved great success using this.”

Rashim said the government can make people aware through mobile messaging 30-15 minutes before lightning starts striking in any particular areas as part of an effective step to check casualties.

Early warning system being considered

Disaster Management Ministry Secretary Mohammad Mohsin said high population density and people’s lack of awareness are the main reasons behind the growing lightning casualties.  

“There are many countries where the lightning frequency is much higher than Bangladesh but the causality is much lower due to less population density, strong warning systems and better awareness.”

He said they have already taken an initiative to plant palm trees as a long-term protection measure, as the number of taller trees such as date palm, betel nut, coconut and fan palm has declined.

As a short-term measure, Mohsin said, they are now planning to build concrete lightning shelters in haors, baors, beels as farmers and fishermen are being the worst victims of the lightning strikes. “We have already built some such shelters in Meherpur’s Gagni upazila.”

Besides, he said, they are focusing on ensuring the installation of lightning arresters in every house to reduce the fatality from such a natural disaster.

The secretary said they are also developing an early warning system so that people can be aware half an hour before the possible lightning strikes.  “We need to set up 723 detection stations across the country for developing the warning system. “We are working on reducing the lightning fatalities and we’re taking various effective initiatives. “

He said people’s awareness is crucial to lessen the lightning casualties.
