DHAKA

Dhaka, the capital of Bangladesh, is among the most climate-vulnerable cities globally. This page gives an overview of what workers in the city go through when impacted by extreme weather events, with a focus on impacts of increasing heat. It presents a background of the workers surveyed in the study from which the data has been borrowed and goes into impacts on work and households of workers, coping strategies adopted by them in the face of such impacts and external support accessible to them.

Some key insights on increasing temperatures include

Workers in Dhaka are generally found working in the readymade garment sector, construction sector or as domestic workers, among other informal and vulnerable sectors of work. They are also found to reside in crowded settlements in extreme weather event prone areas of the city.

Who are these workers?

What is the age of the surveyed respondents?

Most of the workers fall in the age group of 25 to 34 years followed by 35 to 49 years. Broadly, a middle aged section of the population are engaged in Dhaka as informal workers, possibly having ample financial responsibilities.

What is the gender of the surveyed respondents?

Interestingly, a large section of the workers in Dhaka and engaging in the informal sector are women. The readymade garment industry, which has a big contributor to the country’s economy, largely employs women.

Migration Trends and Patterns

Why are people migrating?

Issues in livelihoods practiced, limited work opportunities and low wages at source locations are the main reasons why people are compelled to move to Dhaka in search of better livelihoods and income. A significant share of workers also said they migrated because of a weather event at their home.

Why are migrants choosing certain destination locations?

Majority of the workers choose Dhaka as their destination location as they perceive the city to offer better livelihood opportunities (93%) and/or better incomes (83%). Migrant workers also prioritise Dhaka based on better healthcare related services, which is a major area of concern for them given their precarious living conditions and difficult working conditions.

Who are they migrating with?

Workers tend to move with their spouse, children and parents. As pull factors for migrating to Dhaka also include social reasons like better education, healthcare services, moving with family members makes sense for better access to these facilities on top of aspirations for better incomes.

What duration are migrants moving for?

Majority of the migrants moving to Dhaka live for one or more years even though generally internal migration in the country leans towards seasonal migration. This could be because the city of Dhaka provides more economic opportunities than other destination locations in the country.

How many migrants are negatively impacted by extreme weather events?

Everyone surveyed said they were impacted by extreme weather events across locations, highlighting workers are vulnerable to adverse impacts everywhere.

This came out more prominently as 87% workers faced problems due to weather events both at source locations and even after migrating.

Extreme weather events workers face in cities

Almost 75% respondents were impacted by increasing heat. With global projections around rising heat and increasing incidences of heatwaves, Dhaka’s already vulnerable informal workers are bound to face catastrophic impacts on their work, homes and health.

Along with extreme heat, many workers also experience excessive rainfall and urban flooding, given the city’s geographical location along the banks of a major river. Workers often settle along riverbanks, areas that are particularly prone to flooding. A combination of weather events, including floods and rising temperatures, alongside high levels of humidity, severely affects the well-being of informal workers.

I see a change in the temperature compared to the past 10 years. The heat in Dhaka is increasing. As years go by, it is getting difficult to work on hot days.

Impacts on Work

Heatwaves cause a lot of problems while working inside the factory. Just yesterday, I was working next to a machine, and there was no fan nearby. I told the mechanic to fix the fan because the heat was becoming unbearable. The temperature kept rising, but nothing was done. I even reported it to the office director and requested a fan be installed. A few hours later, I started feeling extremely weak and dizzy. In the end, I passed out. I had a severe headache, and three or four coworkers had to help me by giving me water. This is the kind of condition we work in.

Wage related problems

All workers in Dhaka experience some form of negative impact on their livelihoods, with a staggering 94% reporting wage deductions due to weather-related events. A similarly large proportion of workers report being particularly affected by increasing heat. Since workers already earn very low wages, these deductions create significant ripple effects in their overall household budgeting.

Wage related problems

“I am able to work only half day when the heat is too much. Sometimes if you work half a day, you still don’t get paid at all.”

Productivity losses due to heat

Under heat stress conditions, workers are not able to work at their maximum capacities as they get exhausted sooner. They complained about having to stretch work hours to complete assignments without overtime compensation.

Productivity losses due to heat

“The seasons have become unpredictable and irregular. It disrupts our daily routines. The current extreme heat is particularly difficult to endure. When we cannot adapt to this heat at work, it leads to physical discomfort, and reduces our productivity. As a result, people often take frequent breaks or move around to cope with the harsh conditions.”

Employer negligence

Without wage protections, formal contracts, safe working environments, or access to redressal systems, workers suffer more. When they ask supervisors or employers to address the issues they face because of heat, they are often turned away with negative responses and left to endure the heat.

Employer negligence

“The heat is intense, especially inside the kitchen or the pantry. It feels like a furnace. It’s really difficult to work in such conditions. And when we ask for fans, they say, "If we give you fans, the electricity bill will go up." Some even threaten to deduct our salary if we ask for such basic requirements to be able to pay for the electricity bill”

Impacts on households

Health problems

Workers shared their deep frustration over worsening health problems caused by extreme weather events. As temperatures continue to rise, heat-related risks, including heat stress, dehydration, respiratory problems, digestive issues, and even the risk of fatalities also increase.

Health problems

“Higher temperatures cause our bodies to sweat more, which leads to weakness, nausea, and dizziness. The constant fluctuations in temperature also create additional health problems. On top of that, air pollution, dust, and smoke have also increased in the city. That contributes to various illnesses as well. Sometimes the heat becomes so unbearable that even drinking water can cause vomiting. Fever, colds, and coughs have become very common illnesses we face because of this rising heat.”

Sleep and rest deprivation

Not just outdoors, the heat is unbearable for workers inside their homes as well, which are generally made of materials that trap heat. Workers engaged in labour-intensive jobs complain about poor resting conditions, which in turn affect their health and productivity at work. Altogether, these factors have major impacts on their work attendance, which further leads to economic losses.

Sleep and rest deprivation

“At night, I don’t sleep well because of the heat, and my body feels exhausted. In the morning, I try to leave early, but by the time I check the clock, it’s already past eight. If I go then, the employer will refuse to let me work for the day. So, instead of going and being turned away, I just delay leaving and don’t inform anyone. However, if you don’t notify the employer a day in advance, you won’t be allowed to work the following day either.”

Food and sanitation issues

Food security and sanitation were also reported as major concerns. Rising temperatures often cause food to spoil, leading families to go hungry. Income fluctuations may further affect workers’ ability to afford nutritious food and maintain proper sanitation in and around their homes.

Food and sanitation issues

“Food is also a problem. It gets spoiled because it is so hot inside the house. We cook in the morning and leave it, but by the afternoon it goes bad. Then we have to cook again. Because of bad food, I had diarrhoea. I had to get treatment in Mohakhali.”

Assistance received during and post extreme weather events

Shortage in government support targeting informal workers

9 out ten workers mentioned not receiving any external support when they experienced impacts due to extreme weather events. Under extreme heat conditions, a very small share of workers mentioned some emergency relief from the government. This highlights gaps in the social security landscape and coverage for informal workers, especially in terms of climate responsive measures.

Shortage in government support targeting informal workers

“Government employees have pension schemes and social safety nets, but in construction work, we have nothing like that.”

Issues in accessing existing government support

Some workers spoke about the issues in accessing social security benefits that are in place. This would highlight the need for strengthening last mile delivery of existing social protection infrastructure for better coverage and efficient access.

Issues in accessing existing government support

“If I go to apply to receive the benefits of these schemes, I have to stand in line behind 300 people. That means losing an entire day’s work. But if I work, I can earn 600 to 800 taka and at least bring food home. That income is certain. My application is not certain if it will be successful. By 2 PM they say there’s no rice, no lentils, no oil left for the day—then I’ve lost both my wages and the food.”

Lack of employer support

During in-depth discussions, workers mentioned any support from employers was up to their discretion. There are no mandates or rules around basic support workers should receive to ensure they are able to work properly.

Lack of employer support

“Out of all employers, only 20% actually care and provide proper water. Most don’t bother. They give water, snacks, and even bring lemon water on hot days. Some are kind and attentive. Contractors sometimes include snacks and drinks as part of the job. If they feel generous, they give it—if not, they don’t. It’s not mandatory. Some landlords are very helpful and even go beyond what’s asked.”

Coping mechanisms adopted during extreme weather events

A significant share of workers reported having no coping mechanisms, leaving them completely vulnerable to work-related impacts, household impacts, or both. Most affected workers rely on borrowing from family members, while others take informal loans or use their savings. Incurring debt and depleting savings are negative coping strategies that push workers into deeper financial vulnerability, often resulting in long-term setbacks in their efforts to stabilize their livelihoods. During interviews, workers described adopting short-term measures to make the increasing heat more bearable and to continue working despite the conditions.

Stories from the ground

Akram -

Akram, 28 years old, is the primary earner within his family. A migrant worker, employed in a garment factory in Dhaka, Bangladesh, mentions that during the summer months, heat becomes unbearable. The infrastructure of the factory only makes it worse.

At the factory, Akram says, “In the cutting section where I work, the situation is even worse. We work with fabric, and the area is closed from all sides, making it incredibly hot. The fabric we handle is hot and the sewing machines release heat from their copper motors. Additionally, imagine 200 people working together in a closed space, that body heat adds up. The heat is unbearable.”

The factory sees constant power cuts during the summer, usually due to load shedding. During these periods, with no fans or cooling mechanisms, it becomes impossible for Akram and his fellow workers to stay on the factory floor. They’re forced to step outside near the fire hydrant or stand by the stairwell corner for some relief. In spite of these challenges, he mentions, “The company does nothing. Even if there's no power for 1.5 to 3 hours, they don’t give us leave. We just sit and wait.”

Akram noted health issues are rampant during the summer months especially within the workplace. He spoke about his fellow workers vomiting, experiencing high blood pressure, or feeling dizzy due to the heat.

He recalled, “I remember a tragic incident from a year or two ago. A boy, around my age came to work, climbed the stairs, drank water, and suddenly collapsed from heatstroke. The doctor wasn’t called immediately. When they finally took him to Al-Baraka Hospital, they couldn’t admit him, and then referred him to Dhaka Medical. He died before reaching there. Everyone cried—around 200 workers from our sample department. I believe he died because of the delay and poor medical judgment.”

With no protection mechanisms or support from employers to reduce distress caused to workers during the summer months, the heat will only become further unbearable for workers like Akram.

Razia -

Razia, a 25-year-old domestic worker, moved to Dhaka about 9 years ago, eventually found a home in the city, married, and settled down. During the initial years of her marriage, she took care of the household; however, in 2018, decided to seek employment to cope with the growing financial challenges within the family due to her husband’s frequent illnesses.

Razia mentions that heat during the summer months has gotten worse over the past few years. Her work, which requires constant movement, and life at home in a tin-roofed household, make it extremely challenging during the summer. She mentions,

“when I mop the floor, I have to bend down, and it becomes very hot. I have to turn off the fan while sweeping, which makes it even worse. After cleaning one house, when I go outside, the sun feels scorching. Then I head to the next house and have to climb stairs in the heat. It’s exhausting.”

Razia works part-time in multiple houses, completing tasks such as cooking, cleaning, etc. Additional restrictions placed on workers like Razia make their work even more unbearable. She talked about domestic staff in residential areas not being allowed to use lifts which meant that after entering the building from the scorching sun, she had to climb 5-6 flights of stairs to reach her employer's house. The exhaustion and reduced productivity due to this, significantly impact her ability to work.

To cope with these increasing temperatures, Razia and her family use electric fans to keep themselves cool at home. However, this often leads to extremely high electricity bills and additional financial costs for a family already struggling financially. Razia feels that some support from the government during the period would take her family a long way to cope with these yearly impacts.

“I feel that if they provide some assistance, we could live better, eat better, and generally do better, like if there was rice, lentils, etc., that would be good.”
