BD needs permanent flood resilience strategy

The recent spell of incessant heavy rainfall has once again exposed the extent to which Bangladesh’s agriculture remains dependent on nature. Flooding triggered by torrential rains in Chattogram, Cumilla, Sylhet and many other districts has caused widespread devastation, claiming lives and inflicting severe damage on agriculture, fisheries and livestock.

According to available estimates, more than one hundred people lost their lives, while nearly 100,000 hectares of cropland were submerged. Aus paddy suffered the heaviest damage, with more than 53,000 hectares still under water. Around 9,000 hectares of Aman seedbeds have been destroyed, while vegetables cultivated on nearly 20,000 hectares have also been affected. The full economic cost is yet to be determined, but it is expected to be enormous.

Although floods affected 43 districts, the worst damage was concentrated in sixteen districts, including Chattogram, Cox’s Bazar, Rangamati, Khagrachhari, Noakhali, Cumilla, Barishal, Patuakhali, Bhola, Jhalokathi, Barguna, Bagerhat, Jashore, Meherpur, Naogaon and Habiganj. As field assessments continue, additional districts may be added to this list.

After crop losses, the fisheries sector has suffered the second-largest blow. Floodwaters washed away fish from ponds, shrimp farms and aquaculture projects. Coastal districts such as Chattogram and Patuakhali experienced extensive losses, while overflowing ponds in Cumilla and Rajshahi allowed large quantities of fish to escape. Financial losses in the fisheries sector alone are expected to exceed Tk 4 billion.

The livestock sector ranks third among the worst-affected sectors. Government agencies estimate losses exceeding Tk 800 million from cattle, poultry and duck farming. Approximately 5,000 dairy farms across the country have suffered losses of around Tk 200 million, with poultry losses adding at least another Tk 200 million.

The floods are also expected to reduce national rice production by nearly 300,000 tonnes. Re-establishing Aman seedbeds will require both time and additional financial resources.

Immediate relief operations remain essential. However, relief alone cannot restore livelihoods. Farmers require direct financial assistance to resume cultivation, rebuild their confidence and prepare for the next planting season. A responsible and coordinated response from government, civil society and the private sector will be crucial in helping affected communities recover.

Yet relief and rehabilitation should not become the country’s only response. Bangladesh must begin implementing both short-term protective measures and long-term structural solutions to safeguard crops, livestock and fisheries from recurring flood disasters.

Every year, when rivers overflow, local communities struggle desperately to protect embankments with their own limited resources. In many areas, breached embankments allow floodwaters to inundate cropland, wash away fish from enclosures and destroy valuable agricultural assets. Livestock suffer from shortages of fodder and safe drinking water, while outbreaks of waterborne diseases become increasingly common. Poor drainage systems often prolong waterlogging long after floodwaters have receded.

These are not new problems. They have persisted for decades, and successive governments have largely confined their efforts to temporary emergency responses instead of pursuing permanent solutions.

In today’s world, however, many of these challenges are technically solvable. What is required is political commitment, scientific planning and effective implementation.

Unfortunately, the Bangladesh Water Development Board has traditionally relied on an ad hoc approach to embankment construction and repair. Earthen embankments are built, destroyed by floods, repaired and then destroyed again the following year. This repetitive cycle consumes substantial public resources without providing lasting protection.

It is time to break this cycle.
The country’s flood-prone regions are already well identified. Rather than repeatedly reconstructing vulnerable earthen embankments, Bangladesh should begin piloting durable concrete embankments and flood-control structures in selected high-risk areas. Although the initial investment would be higher, the long-term economic benefits would almost certainly outweigh the recurring costs of emergency relief, reconstruction and compensation.

For a country that remains heavily dependent on borrowed resources for development, it is neither economically prudent nor fiscally sustainable to spend billions every year on disaster relief and rebuilding infrastructure that repeatedly fails.

Bangladesh’s future food security cannot depend solely on favourable weather. Climate change is making rainfall more erratic, floods more destructive and extreme weather events more frequent. Protecting agriculture therefore requires a transition from reactive disaster management to proactive climate resilience.

Modern engineering, advanced forecasting systems, resilient embankments, improved drainage infrastructure, scientific water management and climate-smart agricultural technologies must become integral components of national development planning.

Relief and rehabilitation will always remain necessary after natural disasters. But they should no longer be the centrepiece of Bangladesh’s flood management strategy. The country’s long-term prosperity depends on protecting its farmers before disasters strike-not merely assisting them after they have lost everything.

The true measure of national preparedness is not how effectively relief is distributed after a flood, but how successfully the country prevents avoidable losses in the first place. Bangladesh possesses the knowledge, the engineering capacity and the institutional experience to build a more resilient future. What is needed now is the political will to replace temporary remedies with permanent solutions.
