Bangladesh’s next climate vulnerability may be losing its young people

Bangladesh cannot build lasting climate resilience if young people in its most vulnerable communities see no future there. Closing the gap between climate risk and economic opportunity must therefore become central to the country's adaptation strategy.

On International Youth Day 2026, I found myself confronting a difficult question: what if Bangladesh's next climate vulnerability is not only the number of people exposed to climate change, but also the number of young people leaving vulnerable communities behind?

Across rural and coastal areas on the front lines of the climate crisis, young people are making a rational choice. They are moving in search of education, employment and opportunity. They are looking for a future.

This year's International Youth Day theme, "Different Contexts, Common Aspirations", reflects that reality. Whether they live in coastal communities affected by salinity, flood-prone river basins, drought-affected regions or growing urban centres, young people may face different circumstances, but their aspirations are remarkably similar: education, decent work, security, dignity and a future they can believe in.

This raises an uncomfortable question: what happens when the young people expected to sustain community resilience increasingly see their future elsewhere?

People aged 15–29 account for nearly 28% of Bangladesh's population. Yet the country's demographic dividend is far from guaranteed. The 2023 Labour Force Survey found that around 1.94 million young people were unemployed, about 69% of them in rural areas. It also found that 39.8% of people aged 15–24 were not in employment, education or training.

We tend to view these as labour-market statistics. We should also see them as climate statistics.

A climate-vulnerable community cannot build lasting resilience if much of its future workforce – its entrepreneurs, innovators and leaders – remains disconnected from opportunity.

I describe this as Bangladesh's "adaptation opportunity gap": the widening mismatch between where climate risks are greatest and where young people believe opportunities exist.

Climate risks remain concentrated in rural and coastal Bangladesh. Education, decent work, finance, innovation and investment remain disproportionately concentrated elsewhere.

Young people are not simply migrating away from climate risk. They are migrating towards opportunity.

A young person leaving a coastal village for Dhaka may simply be responding to the absence of decent work or higher education. But the city does not necessarily offer security. Rural vulnerability may instead be exchanged for precarious employment, informal housing, extreme heat and urban flooding. Under a pessimistic scenario, the World Bank estimates that Bangladesh could have 13.3 million internal climate migrants by 2050.

The question is not whether young people will migrate. It is whether migration becomes a pathway to opportunity or another form of vulnerability. There is also another choice to consider: how do we make staying viable?

Answering that question requires us to rethink adaptation.

Bangladesh has become adept at protecting infrastructure and livelihoods. But who will maintain local water systems? Who will manage early-warning information? Who will introduce new technologies into agriculture? Who will build enterprises around renewable energy, water management and ecosystem restoration?

Young people are not simply beneficiaries of adaptation. They are part of the infrastructure that makes adaptation possible.

This is particularly important for young women.

Bangladesh's latest Multiple Indicator Cluster Survey found that 47.2% of women aged 20–24 had married before turning 18. The figure was 49.4% in rural areas and 62.5% among women from the poorest households.

Climate change does not cause child marriage. The practice has deep roots in poverty, gender inequality and social norms. Climate shocks can, however, intensify those pressures by destroying livelihoods, disrupting education and increasing insecurity. For poor households facing repeated floods, erosion, salinity intrusion or income loss, marrying off a daughter can become a desperate coping strategy.

Climate vulnerability can therefore narrow a girl's future as surely as it can destroy a family's home.

Adaptation must also be an investment in choices. A girl who stays in school, acquires skills, secures decent work and has a voice in decisions has greater agency over whether and when to marry, whether to migrate and whether to build her future locally.

Yet young women are too often consulted rather than empowered. If adaptation is to be transformational, young women and men must move from the margins of programmes to the centre of decision-making.

How, then, do we close the adaptation opportunity gap for young people?

First, make adaptation an economic strategy. Climate finance should support rural green enterprises, climate-smart agriculture, renewable energy, water stewardship and ecosystem restoration – while connecting young people to finance, technology and markets.

Second, invest in young women's choices through education, skills, productive assets, decent work and leadership – not simply awareness or participation.

Third, connect rural adaptation with urban planning. Migration will continue. Secondary cities need housing, employment, services and climate-resilient infrastructure so that mobility becomes a route to opportunity rather than another layer of vulnerability.

Finally, measure adaptation differently. Success should be judged not only by how many people were trained, but also by how many livelihoods were created, how many young people influenced decisions and whether communities can sustain investments.

Perhaps the most important question is this: did our investment give a young person a reason to stay, return or invest in their community?

This is not an argument against migration. Young people have the right to leave. The point is that they should also have the right to stay.

For three decades, development organisations have helped communities become more resilient to climate shocks. The next challenge may be harder: how do we make climate-vulnerable rural communities resilient to the loss of their own young people?

The next frontier of climate adaptation is not simply helping people survive where they live. It is ensuring that they can imagine a future there.

If Bangladesh fails to close its adaptation opportunity gap, its greatest climate vulnerability may not be the infrastructure it failed to build. It may be the generation it failed to retain.
