‘Health of millions in Bangladesh at risk due to climate change’
UNB :
Climate change is affecting the Bangladeshi population’s well-being, impeding poverty reduction, and hindering progress towards a net-zero future, says a new report.
A recent report by the Grantham Research Institute on Climate Change and the Environment and Centre for Climate Change Economics, authored by Lauren O’Leary, Shouro Dasgupta, PhD, and Professor Elizabeth JZ Robinson highlighted that a 46% increase in extreme weather events are evident in Bangladesh.
In 2021, the summer season experienced a 0.49°C temperature rise, causing infants to face 12 additional heatwave days and lead to higher heat-related deaths.
The study shows a 148% surge in heat-related fatalities among individuals aged 65 and above, resulting in 1,430 deaths during 2017-2021.
Dr. Shouro Dasgupta, Visiting Senior Fellow of Grantham Research Institute, LSE and one of the authors of the report stated “Climate change threatens to reverse decades of Bangladesh’s remarkable progress in public health, especially in child and maternal health.
Evidence-based policies that take into account local context can reduce many of these negative effects.”
The report highlighted that Bangladesh’s public health is being seriously affected by climate change through disasters like droughts, floods, and cyclones, which are destroying land, damaging health facilities, and harming people.
Vulnerable people, including the young, elderly, and those with health issues, suffer significantly during extreme heat and heatwaves.
Bangladesh, consistently ranking among the worst countries for air pollution, sees high mortality rates due to respiratory infections, lung cancer, and cardiovascular diseases.
Shockingly, the death toll from ambient air pollution reached 101,500 in 2019 and 112,700 in 2020.
Moreover, air pollution is high in both rural and urban areas. 24,000 people in the Dhaka region alone were estimated to have died prematurely due to air pollution between 2005 and 2018.
Additionally, women and children are more likely to be exposed to indoor air pollution because only 23% of the population has access to clean cooking fuels.
Professor Dr. Ahmad Kamruzzaman Majumder, Chairman, Department of Environmental Science, Stamford University Bangladesh and Chairman, Center for Atmospheric Pollution Studies (CAPS) mentioned “Local heat wave drivers are influencing the upward trend of Global Climate Change.
Due to this the number, intensity and extent of heat waves are increasing, on the other hand, the use of fossil fuels is accelerating both rising temperature and air pollution and creating multifaceted risks for public health.”
Climate change is disrupting ecological systems, including floods, droughts, and changes in rainfall patterns are expected to negatively impact food, nutrition, and livelihoods in Bangladesh.
Moreover, climatic changes are increasing disease vectors, evident in the 2022 surge in dengue cases linked to high rainfall and temperature in Dhaka.
Dengue outbreaks are expected to worsen due to favourable climate conditions boosting mosquito populations in this country. Additionally, climate change is impacting mental health, contributing to conditions like anxiety and depression.
The report highlighted those earlier policies like the Health and Population Sector Program (HPSP) focused on healthcare improvements without addressing climate change explicitly.
The initial National Health Policy (NHP) from 2000 lacked comprehensive support for chronic diseases, potentially reducing resilience to climate-induced heatwaves.
The 2011 NHP saw revisions but no significant shift in focus. Bangladesh’s healthcare system faces inequality issues, with disparities in health indicators among wealthy and deprived households.
The Health Care Financing Strategy (20120-2032) aims to advance health financing but faces criticism due to depleting budgetary allocations hindering progress toward universal health coverage (UHC).
Recent initiatives signal a shift toward climate-conscious health policies.
Bangladesh introduced the National Action Plan on Short-Lived Climate Pollutants (SLCPs), aiming to reduce black carbon emissions by 40% and methane emissions by 17% by 2030.
