Community Values Enhance Bangladesh’s Cyclone Preparedness

Bangladesh is highly prone to tropical cyclones (TCs), storm surges, and floods. In response to these persistent threats, the country has developed a multi-level Disaster Management Committee (DMC) system, a framework that operates across all levels of government, from national to community.

This multi-tiered disaster management programme includes a partnership with the Bangladesh Red Crescent Society, which plays a key role in disseminating early warnings and facilitating timely evacuations during emergencies.

Non-governmental organisations (NGOs) and international agencies have also contributed significantly to community-based disaster preparedness, shelter construction, and livelihood recovery programmes.

A history of cyclone impacts in Bangladesh

Bangladesh has endured several devastating cyclones in the past, including the Great Bhola Cyclone in 1970 and Cyclone Gorky in 1991, two of the deadliest tropical cyclones in recorded history, causing approximately 500,000 and 147,000 deaths, respectively.

Although more recent cyclones, such as Sidr (2007), Aila (2009), and Amphan (2020), have resulted in significantly fewer fatalities, the economic losses remain substantial, totalling around $10 billion, or roughly 3.5% of national GDP.

Tropical cyclones not only cause widespread destruction and loss of life but also trigger flooding, damage infrastructure, and exacerbate salinity intrusion. Storm surges frequently submerge villages and agricultural land, pushing already vulnerable communities further into poverty.

Effectiveness of early warning systems and local institutions

Given the increasing frequency and intensity of extreme weather events, assessing the effectiveness of Bangladesh’s DMC system is essential. Understanding gaps in communication, resource allocation, and support for vulnerable populations can help strengthen disaster response and improve long-term climate resilience.

A 2026 study titled “Beyond warnings and shelters: local institutions and trust build cyclone resilience in Bangladesh”, published in npj Natural Hazards, examined how coastal communities experience cyclones and evaluated the effectiveness and equity of early warning systems and government responses.

The study found that households across all surveyed areas reported high exposure to tropical cyclones, with an average rating of 4.61 out of 5. Offshore island communities experienced the highest levels of exposure. The most affected sectors included crops, fishing assets, livestock, and housing.

Despite recovery efforts, many communities continue to face unmet needs. Access to drinking water was identified as the most urgent issue in five of the seven districts studied, followed by housing repairs, agricultural and fisheries inputs (such as fishing nets), food aid, and veterinary support.

The Cyclone Preparedness Programme (CPP), jointly managed by the government and the Bangladesh Red Crescent Society, emerged as the most effective warning system. CPP volunteers conduct door-to-door visits to alert households and encourage evacuation. The programme achieved over 72% coverage across all districts, peaking at 90% in Bhola—outperforming mass media, social media, and word-of-mouth channels.

Participants highlighted that trust in local volunteers was key to the programme’s success. One volunteer noted that personal relationships with households improved response rates, while residents expressed greater confidence in warnings delivered through familiar, trusted individuals.

Barriers to evacuation and the importance of shelter quality

The study also found a strong correlation between shelter quality and evacuation rates. In districts such as Barguna and Satkhira, where shelters were well-maintained, with clean water, proper sanitation, and adequate space, residents were more willing to evacuate.

However, evacuation decisions are complex and influenced by multiple factors. Concerns about theft, personal safety, and overcrowding in shelters often discourage people from leaving their homes. Women, in particular, reported fears related to privacy and safety in mixed-gender shelters.

Other barriers included false alarm fatigue, economic concerns, distance to shelters, and distrust of aid distribution systems. In some areas, residents chose to stay behind to protect livestock or property, highlighting the need for more inclusive and context-specific solutions.

Towards more inclusive and effective disaster resilience

The study concludes that building resilience in Bangladesh requires a shift towards context-sensitive and community-driven strategies. Key recommendations include:

• Investing in better-quality and more accessible cyclone shelters
• Integrating trusted local networks, such as religious institutions, into warning systems
• Designing equitable aid programmes that prioritise vulnerable groups
• Developing livelihood-specific recovery support

Future research should focus on long-term impact assessments, gender-sensitive decision-making, and cost–benefit analyses of different communication strategies.
