The looming threat of sea level rise in Bangladesh

The recent report by the International Centre for Climate Change and Development (ICCCAD) paints a grim picture of Bangladesh’s future, with nearly nine lakh people in southern Bangladesh facing displacement by 2050 due to sea level rise.

This impending crisis is exacerbated by projections indicating that between 12 per cent and 18 per cent of the country’s coastal areas will be submerged by the end of the century.

The implications of such displacement are dire, with devastating consequences for food crops and the livelihoods of coastal communities. Already, Bangladesh experiences an annual average loss of $1 billion due to cyclones, further exacerbating the economic strain on the nation.

Millions could face displacement, which underscores the urgency of the situation.

The loss of arable land and disruptions to fisheries due to saline waters will disproportionately affect the poorest communities, for whom these resources are vital sources of sustenance.

These impacts are not just environmental but have far-reaching socio-economic implications, threatening food security and exacerbating poverty.

Bangladesh’s vulnerability to extreme weather events is well-documented, ranking as the seventh most vulnerable to climate change globally.

However, the government’s proactive measures, such as the Cyclone Preparedness Programme and investments in adaptive technologies, have been instrumental in reducing the loss of lives during cyclones.

Bangladesh is heavily reliant on international support for its relief work as the readiness and resources of local rescue teams and the government is scarce.

For years, NGOs as well as different bodies of the United Nations – such as the International Children Emergency Fund (UNICEF) and the Development Programme (UNDP) – and other international organisations have provided economic support and humanitarian relief work to vulnerable parts of Bangladesh.

These are extremely helpful in providing emergency relief, especially for remote coastal areas.

Nevertheless, the scale of the challenge ahead demands a concerted international effort to mitigate the impacts of climate change.

Bangladesh’s efforts in adaptation and resilience serve as a model for other vulnerable nations, but they cannot tackle this crisis alone.

Urgent action is needed to curb emissions and limit global warming to prevent further escalation of the climate crisis and its devastating consequences on vulnerable communities like those in Bangladesh.
