Climate health funding shrinks despite rising risks, experts warn

“Bangladesh needs stronger evidence to establish the link between climate change and health vulnerabilities. Robust, granular and peer-reviewed research can help quantify both economic and non-economic losses, strengthen climate rationale, and unlock greater access to international climate finance. Climate risks are systemic and addressing them requires systemic resilience built through data-driven policies, interdisciplinary collaboration and long-term investment. As climate finance declines globally and health-related climate risks intensify, budget allocations should reflect the growing vulnerabilities rather than shrink. Effective climate action will depend on integrating science, finance, policy and local knowledge to design interventions that are credible, targeted and capable of delivering lasting resilience.”

“Bangladesh allocates only 0.38% of its climate-related expenditure to the health sector, even though climate change is increasingly affecting public health. We have already identified key policy and financing gaps, and now the focus should be on turning research evidence into concrete policy action. If even one of the five recommendations from this study is implemented, it could help increase climate financing for health and strengthen resilience. Climate and health must be addressed together through stronger evidence generation, capacity building, and sustained investment. The time has come to move beyond discussions and translate knowledge into action.”

“These studies unveiled the impacts of climate change on human health and assessed how climate finance is being allocated, tracked, and made more transparent and accountable. Climate challenges are increasingly affecting health systems, livelihoods, and vulnerable communities, making interdisciplinary collaboration essential. We hope these findings will contribute to stronger policy recommendations, improved financing mechanisms, and more resilient health and climate systems at both national and local levels.”

“Research must not end with presentation; it should translate into policy and practice. Evidence is often shared but not effectively used, which limits real impact. Strong collaboration among research organizations, government, and development partners is essential to address climate and health challenges. Resources are increasingly limited, so we must focus on efficient use through cooperation and sustained evidence generation. Policy platforms should integrate health within broader climate discussions, ensuring systems thinking rather than isolated approaches.”

“The study found strong associations between the use of saline-contaminated water, occupational exposure, and increased reproductive health risks, including pelvic inflammatory disease (PID) symptoms and menstrual irregularities. Women facing multiple health burdens were significantly more vulnerable to these outcomes. Despite recognition of climate and health as a national priority, climate-health spending is still largely concentrated in infrastructure projects, while critical areas such as surveillance, workforce development, research, preparedness and service continuity receive far less attention. Climate-health priorities must be made more visible within budgeting systems, supported by sustained financing, and better aligned with national adaptation plans and long-term resilience goals.”

“Climate-health financing remains a grey area because we still lack a clear mechanism to identify and tag health-related climate expenditures. Building a resilient health system requires recognizing climate-induced health risks, strengthening frontline health workers, and integrating community realities into policy and financing decisions. The priority now is to connect evidence, financing, and community needs so that climate resilience becomes an operational reality rather than merely a policy commitment.”

“Cognitive behavior and developmental issues are often overlooked, and mental health remains a taboo subject. We urgently need recognition of mental health, particularly for adolescents and youth, in the health budget. Climate health budget planning must adopt a bottom-up approach prioritizing impacted communities and vulnerable groups, while also valuing their traditional knowledge and adaptation techniques.”

“Until evidence is recognized within international climate assessment processes, it remains difficult to bring these issues effectively to global negotiation and financing forums. Climate-resilient health systems should also incorporate low-carbon approaches, aligning with evolving global frameworks. Going forward, climate-health research must be presented not only as a public health concern but also as a strategic investment priority for climate finance.”

“Climate research often fails to adequately reflect the lived experiences of women and children. We need stronger participation of women-led organizations in climate finance and policy processes to ensure resources reach the most vulnerable populations. Without understanding the additionality of financing requirements in regard to differentiated vulnerability context and cost efficiency, climate-health investments will struggle to attract grants-based financing for addressing very localized and intersectional health vulnerabilities.”

“Climate-related health impacts often emerge gradually, making long-term disease surveillance essential for establishing clear links between climate change and health outcomes. Integrating climate-sensitive disease reporting into the existing health system would help track trends, identify seasonal patterns, and guide timely interventions. Addressing these challenges also requires stronger collaboration across sectors, including health, fisheries, agriculture, transport, and labor.”

“Climate adaptation cannot depend solely on short-term projects. We will face shrinking funding once we graduate from LDC status. We must need sustained investments in local health services, equitable climate-budget allocation and greater support for vulnerable communities, including those affected by river erosion and displacement. This essentially requires a coordinated, interdisciplinary approach not only to reduce health risks for vulnerable communities and frontline workers but also to distribute financial responsibility more effectively across government sectors.”

“Despite Bangladesh being globally recognized for its climate policy leadership, critical gaps remain in defining what truly qualifies as climate finance and how it is tracked across sectors, particularly in health. Weak surveillance systems, limited forecasting integration, and highly centralized planning further reduce the effectiveness of local responses. Evidence also shows significant productivity losses due to climate stressors like heatwaves, alongside growing risks of displacement and climate-induced health burdens. Without stronger data systems, clearer definitions, and decentralized planning, climate-health financing risks remaining fragmented and under-prioritized.”

“To truly understand climate-health impacts, we must start with land-use patterns and zoning. Without a clear zonal framework such as coastal classification, we cannot design effective health systems tailored to local realities. This requires long-term action research, with control-based monitoring to capture real reproductive and broader health impacts, including male vulnerability as well. We also need to quantify lost working hours due to climate stress and integrate local government into health system activation.”

“The findings show a clear link between climate change and women’s reproductive health risks.  We need further research to understand how recurring climate shocks and disruptions in healthcare services increase vulnerabilities and identify effective adaptation measures.”

“Beyond technical research, what we urgently need is a coordinated sectoral platform for climate and health where data, adaptation solutions, and institutional responses can be systematically mapped and shared. Effective climate resilience cannot be built in isolation. Health surveillance must be linked with media and communication strategies so that communities are better informed and prepared through structured public messaging and early warning systems. At the same time, we must assess how existing local government allocations are being utilized for climate-health needs. Finally, innovative financing, including low-cost insurance mechanisms and private sector engagement, should be explored to support vulnerable populations.”

“Climate impacts are already affecting the daily lives of women, children and families through limited access to basic services. I’d suggest further investigation into issues such as women's increased workload in aquaculture zones and broader household water insecurity.”

“What makes this research particularly powerful is the way it frames the climate health nexus through a cost lens. In development finance, cost packaging is critical because once we quantify the health and economic burden, investment decisions become far more actionable. This study can help identify unit costs and opportunity costs in reproductive health impacts, making adaptation finance more targeted.”

“It is critical to distinguish whether allocations fall under the development budget or the revenue budget, as investments can blur this line.  Allocations must be more transparent; otherwise, it is not possible to ensure effective budgeting within the health sector. We also need to identify both macro- and micro-level financing opportunities to support growth.”
