Bangladesh’s proposed record climate allocation signals stronger adaptation efforts, but experts warn declining health-sector funding, implementation gaps, and inequitable climate finance could weaken resilience for vulnerable communities.
Bangladesh is set to propose a record allocation of around Tk 5.2 trillion for climate change-related interventions in its 2026-27 national budget, marking an increase of nearly 25 percent from the previous year. The move signals one of the country’s most significant policy commitments to climate adaptation amid rising environmental risks, according to official and policy sources.
The proposed allocation comes as Bangladesh continues to face intensifying climate impacts, including cyclones, floods, droughts, river erosion, heatwaves, sea-level rise and salinity intrusion. These hazards are increasingly affecting millions of people, particularly in coastal and riverine regions.
Officials and climate advocates say climate change is no longer only an environmental issue but a central development and macroeconomic risk requiring sustained and large-scale adaptation investment.
Under the proposed plan, major spending is expected on coastal embankment strengthening, flood management, safe water supply, afforestation and biodiversity protection, renewable energy expansion, climate-resilient agriculture and resilient infrastructure development. Bangladesh’s Ministry of Youth and Sports and the Department of Youth Development (DYD) are not among the 25 ministries and divisions receiving climate-relevant allocations.
Health sector concerns amid rising climate budget
While the record allocation reflects strong policy momentum, experts warn of an emerging imbalance in sectoral priorities, particularly the declining integration of health within climate finance.
Data presented at a recent policy dialogue in Dhaka show that the share of climate-related allocation within the health services budget fell from 2.74 percent in 2021-22 to 1.97 percent in 2025-26. Over the same period, the health sector’s share of the national climate budget also declined from about 2.5 percent to 1.5 percent.
Analysts caution that this dual decline suggests structural underinvestment in climate-health integration, weakening long-term adaptation outcomes. They argue that infrastructure-heavy spending alone cannot address the growing burden of climate-related disease and health system stress.
Climate change reshaping public health risks
Public health specialists say climate change is already altering disease patterns across the country.
Rising temperatures are linked to increased heatstroke, dehydration and cardiovascular stress. Irregular rainfall and waterlogging are contributing to the spread of dengue and chikungunya, while floods and cyclones continue to trigger outbreaks of diarrhoeal diseases, cholera and other waterborne infections.
Salinity intrusion into drinking water has also been associated with hypertension, kidney disease and pregnancy complications, particularly in coastal districts. Experts further warn that climate-induced displacement is likely to increase mental health pressures, malnutrition and strain on already overstretched health systems.
Women and adolescents facing heightened risks
Findings presented by the Centre for Participatory Research and Development (CPRD) at a policy dialogue held at BRAC Centre highlight significant reproductive and maternal health risks among women and adolescents in climate-affected coastal areas.
Nearly half of the surveyed women reported menstrual irregularities, severe pain and other reproductive health complications. Cases of miscarriage, pre-eclampsia and childbirth-related complications were also reported to be increasing.
Alarmingly, 82.5 percent of respondents identified a lack of safe drinking water and sanitation as a key factor worsening health risks.
Experts note that reproductive and maternal health impacts remain under-addressed in climate policy, which continues to focus more heavily on infectious diseases such as dengue and diarrhoea.
Heavy reliance on short-term climate projects
Researchers highlight that more than 60 percent of climate-health expenditure depends on short-term development projects, raising concerns over sustainability.
They warn that once projects end, essential systems such as disease surveillance, epidemic preparedness, emergency response, training and research often lose continuity, undermining the development of a resilient climate-responsive health system.
Health remains marginal in climate finance architecture
According to Bangladesh Climate Change Trust Fund data, out of 877 funded projects, only three were implemented by the Health Services Division, with less than 1 percent of total funding allocated to the sector.
Experts say this reflects the continued structural marginalisation of health within Bangladesh’s climate finance system despite its growing importance as a frontline climate impact area.
Financing gap threatens adaptation goals
The National Adaptation Plan for the health sector estimates that Bangladesh will require around $140 million over the next five years to build a climate-resilient health system.
The funding is intended for upgrading health facilities, strengthening disease surveillance, improving emergency preparedness, expanding research capacity and training health workers.
However, current financing trends indicate a significant gap between needs and available resources, raising concerns about long-term system resilience.
“People-centred adaptation must guide climate finance”
Economists and policy analysts say the record climate allocation is a strong signal of commitment, but its effectiveness will depend on targeting, implementation and accountability.
They stress that climate adaptation must go beyond infrastructure and place stronger emphasis on health systems, livelihoods and vulnerable populations.
Sohanur Rahman said climate finance governance must be transparent, accountable and justice-driven. “A just transition is impossible without protecting health and nutrition. Climate finance must prioritize people-centred adaptation, especially for climate-affected communities in coastal and riverine areas.”
He added that adaptation requires deeper structural shifts: “We need sustainable transport systems that reduce emissions while improving access and equity. At the same time, locally led adaptation must be strengthened through direct investment in vulnerable regions, especially for women, youth and workers facing climate-induced displacement and rising salinity.”
He further emphasized renewable energy reform: “Removing taxes and duties on solar panels and renewable energy technologies should be a priority in the upcoming budget to accelerate a fair and inclusive energy transition.”
Outlook: implementation gap remains the key challenge
Bangladesh continues to be internationally recognized for its climate adaptation efforts, and the proposed budget reinforces that trajectory with its largest-ever climate allocation.
However, experts caution that the decisive factor will not be the size of the budget but how effectively it is implemented and whether it addresses structural gaps, particularly in health integration and equity.
Without that shift, they warn, climate finance risks remaining impressive on paper while vulnerable communities continue to bear the rising human cost of climate change.
