There is a particular cruelty embedded in the geography of climate change. The nations that have contributed least to the warming of this planet are the ones standing closest to its most violent consequences. Bangladesh understands this cruelty along its 710-kilometre coastline.
The coastal region of Bangladesh, stretching across 19 districts, is regularly struck by cyclones, floods, sea-level rise, salinity intrusion, heavy rainfall, and prolonged waterlogging. These climate hazards severely impact livelihoods, food security, healthcare, housing, and employment in the region. These are not projections; they are recurring facts of life for tens of millions of people who did not choose to live at the edge of catastrophe, but were simply born there.
According to the World Risk Report 2025, Bangladesh ranks 11th in global risk, while the Germanwatch Climate Risk Index 2026 places the country 13th globally in long-term climate vulnerability. We are consistently at the top of every list we least want to be on. And yet when the conversation shifts from vulnerability to finance, Bangladesh falls precipitously from view.
Coastal zone management in Bangladesh has never suffered from a shortage of policy ambition. What it has suffered from, consistently and painfully, is a shortage of money arriving at the right time, in the right form, to the right people.
Bangladesh has established over 200,000 hectares of coastal green belts, primarily with mangrove plantations, to protect vulnerable coastal regions against cyclones, high tides, and erosion. Bangladesh's National Adaptation Plan, approved in October 2023, emphasises sustainable land use through reforestation, soil restoration, land zoning, and adaptive agricultural practices. These are real achievements, and they deserve recognition. But the full picture is considerably less reassuring. Salinisation in coastal regions increased from 0.83 million hectares in 1973 to 1.05 million hectares in 2009, and currently impacts more than 53% of the country's coastal areas. The green belts are rising; the salt is rising faster.
The structural problem is not effort. It is the fundamental mismatch between the scale of coastal degradation and the scale of financing directed at reversing it. Coastal zone management requires long-term, predictable investment in embankments, tidal river management, salinity-resistant agriculture, community relocation, and ecosystem restoration. What it typically receives is fragmented project funding, short grant cycles, and the exhausting administrative burden of navigating an international climate finance architecture that was not designed with countries like Bangladesh in mind.
The world arrived at COP30 in Belém last November carrying both promises and contradictions. The UN Environment Programme's Adaptation Gap Report 2025 estimated that the global adaptation finance gap sits somewhere between USD 284 billion and USD 339 billion per year for developing countries, while the Climate Policy Initiative reported that only 5% of total climate finance flows are directed toward adaptation. Five per cent. For the dimension of the climate crisis that is already here, already destroying coastlines and harvests and futures, the world's financial architecture allocates five per cent of its attention. In 2023, developed nations provided just under USD 26 billion in adaptation finance against a need that the same UNEP report estimates will reach between USD 310 billion and USD 365 billion per year by 2035. The arithmetic of this gap is not merely alarming; it is, for coastal Bangladesh, a question of survival.
It would be dishonest to lay every burden at the door of international inaction. Bangladesh's own management of coastal finance deserves scrutiny as rigorous as the scrutiny we apply to the promises made in Baku and Belém.
The Ministry of Disaster Management and Relief adopted a 20-year inclusive and rights-based National Action Plan for 2022 to 2042, but even after four or five years the government's initiative and progress remain unclear. It is not enough to adopt an action plan; effective implementation must begin immediately. This observation, made by coastal civil society researchers, carries a weight that no amount of official optimism can dissolve. Bangladesh excels at building policy frameworks; it has been far less consistent at building the institutional machinery that transforms those frameworks into tangible outcomes for the woman whose paddy field is now brackish water, or the fisherman whose boat was swept away in the last cyclone.
