By the end of this article, you'll have a comprehensive understanding of the health implications of climate change and the steps we can take to protect ourselves and future generations. Let's embark on this journey towards a healthier, more sustainable future.
THE URBAN CHALLENGE: CITIES AS EPICENTRES OF CLIMATE CHANGE
THE URBANISATION TREND
As we look towards the future, the trend of urbanisation is set to continue at an unprecedented pace. By 2050, it's projected that nearly 70% of the global population will reside in urban areas. This shift is driven by various factors, including increased job opportunities and easier access to goods and services in cities. However, this urban migration brings with it a host of challenges that intersect with climate change and public health.
URBAN HEALTH RISKS
The concentration of people in cities amplifies the health risks associated with climate change. Urban residents face a myriad of issues, including:
Inadequate housing and transportation systems
Inefficient waste management
Urban heat islands
Air quality that falls short of World Health Organization (WHO) guidelines
These factors combine to create environments that are particularly vulnerable to the effects of climate change, making cities the epicentres of this global crisis.
LIFESTYLE CHANGES AND HEALTH IMPACTS
The urban lifestyle often leads to shifts in dietary habits, with a move from fresh foods to processed alternatives. This dietary change, coupled with a lack of green spaces and limited opportunities for active transportation like walking or cycling, contributes to reduced physical activity levels. These lifestyle factors not only impact individual health but also exacerbate the effects of climate change on urban populations.
PROJECTED HEALTH CONSEQUENCES
The World Health Organization paints a sobering picture of the future, estimating that between 2030 and 2050, climate change will be responsible for approximately 250,000 additional deaths per year. These fatalities are expected to result from malnutrition, malaria, diarrhoea, and heat stress – all conditions that are closely linked to changing climate patterns and urban living conditions.
HEALTH CONSEQUENCES OF CLIMATE CHANGE
EXTREME HEAT AND ITS EFFECTS
One of the most direct and severe impacts of climate change on human health is the increase in extreme heat events. The Lancet Countdown, an international collaboration tracking climate change's health effects, has highlighted several consequences of extreme heat:
Reduced ability to engage in outdoor physical activities
Decreased work capacity and school attendance
Exacerbation of mental health conditions
These impacts are not distributed equally, with vulnerable populations such as the elderly, children, and those with pre-existing health conditions being disproportionately affected.
RISE IN INFECTIOUS DISEASES
The changing climate is also altering the landscape of infectious diseases. Increased atmospheric concentrations of greenhouse gases are playing a significant role in the emergence and spread of various pathogens:
Water-borne diseases are becoming more prevalent due to changes in water temperature and quality
Air-borne pathogens are finding new transmission routes
Food-borne illnesses are on the rise as climate change affects food production and storage
Of particular concern is the expansion of vector-borne diseases. The warming of coastal brackish waters has led to an increase in cholera-causing vibrios. Additionally, the number of months suitable for malaria transmission by Anopheles mosquitoes has grown, heightening the risk of malaria outbreaks in previously unaffected areas.
EMERGING DISEASE THREATS
Climate change has also facilitated the spread of other mosquito-borne diseases such as chikungunya, Zika, and dengue fever. While socioeconomic development, public health interventions, and medical advances have reduced the global burden of infectious diseases, climate change threatens to undermine these efforts, potentially reversing hard-won progress in disease eradication.
VULNERABLE REGIONS AND POPULATIONS
GEOGRAPHICAL HOTSPOTS
While climate change is a global phenomenon, certain regions of the planet are at greater risk due to their geographical and socioeconomic characteristics. The United Nations Intergovernmental Panel on Climate Change (IPCC) has identified drought as a particularly pressing issue. Between 2012 and 2021, compared to the period from 1951 to 1960, 29% more of the global land surface experienced extreme drought for at least one month each year.
EXTREME WEATHER EVENTS
Recent years have seen devastating extreme weather events across the globe:
Floods in Australia, Brazil, China, Western Europe, Malaysia, Pakistan, South Africa, and South Sudan
Wildfires in Canada, the United States, Greece, Algeria, Italy, Spain, and Turkey
Record-breaking heatwaves in Australia, Canada, India, Italy, Oman, Turkey, Pakistan, and the United Kingdom
These events have had severe consequences, particularly for vulnerable populations, with heat-related deaths increasing by 68% between 2017-2021 compared to 2000-2004.
SOCIOECONOMIC FACTORS AND VULNERABILITY
The IPCC emphasises that vulnerability to climate change impacts is strongly associated with the ability of systems, institutions, and humans to adapt to potential harm, exploit opportunities, or respond to consequences. This adaptive capacity depends on various factors, including age, gender, and socioeconomic status, which play central roles, especially in poorer areas more vulnerable to climate change.
MOST AFFECTED GROUPS
The most vulnerable and disadvantaged groups bear the brunt of climate change impacts:
Women and children
Ethnic minorities
Poor communities
Migrants
Elderly populations
Individuals with pre-existing health conditions
These groups often face compounded challenges as climate change compromises many of the fundamental social factors essential for maintaining good health, such as livelihoods, equality promotion, and access to healthcare and social support structures.
MITIGATION AND ADAPTATION STRATEGIES
ENERGY CHOICES AND CLIMATE ACTION
The fight against climate change primarily revolves around energy choices. Limiting the use of fossil fuels and promoting renewable energy sources are crucial steps. However, a broader approach is necessary, embracing the principle of co-benefits that can significantly contribute to climate change mitigation.
NATURE-BASED SOLUTIONS
Nature-based solutions are emerging as a key element of sustainable urban planning and climate change adaptation. These solutions have the potential to reduce the urban heat island effect while also providing additional benefits:
Improved psychological well-being
Enhanced social relationships
Increased physical activity, especially among children
EFFECTIVE COUNTERMEASURES
A range of measures can be implemented to combat climate change and its health impacts:
Enforcing air quality standards
Reducing industrial emissions
Transitioning to clean fuels and renewable energy sources
Decreasing urban traffic
Implementing energy efficiency standards
Reducing automobile emissions
Improving access to public transportation
THE IMPORTANCE OF ACTIVE TRANSPORT
The latest Lancet Countdown report for Europe suggests that significant co-benefits can result from urban strategies based on enhancing "active transport" such as walking and cycling. These strategies can increase physical activity levels, leading to positive health outcomes. Additionally, shifts towards healthy and sustainable diets can reduce deaths attributable to poor nutrition, such as excessive red meat consumption.
URBAN PLANNING FOR CLIMATE RESILIENCE
VULNERABILITY OF URBAN AREAS
Urban areas are particularly susceptible to climate change, especially due to the expected increase in heatwaves. The effects on health can be exacerbated by the urban heat island phenomenon, which is caused by the high density of buildings and the use of materials that impede natural transpiration.
GLOBAL ADAPTATION AGENDA
In November 2022, at the United Nations climate conference in Sharm el Sheikh, Egypt (COP27), world leaders launched the Adaptation Agenda for climate change. This agenda aims to improve the resilience of 4 billion people living in the communities most vulnerable to the climate crisis by 2030.
KEY THEMES FOR ADAPTATION
The Adaptation Agenda outlines the first globally shared plan of 30 adaptation outcomes by 2030. The defined themes include:
Water management
Food and agriculture
Cities, settlements, and key infrastructure
Health
Poverty alleviation and livelihoods
Terrestrial ecosystems
Oceans and coastal ecosystems
CLIMATE AND PREVENTION: A UNIFIED APPROACH
SYNERGIES IN HEALTH AND CLIMATE ACTION
The convergence of climate change mitigation policies and disease prevention can lead to a significant reduction (up to 40-50%) in the incidence of chronic diseases such as cancer, diabetes, and cardiovascular, respiratory, and neurological diseases. This approach not only improves public health but also offers substantial economic benefits.
PREVENTIVE POLICIES BEYOND HEALTHCARE
Preventive policies implemented outside the healthcare system, such as those related to nutrition, transportation, and agriculture, are crucial. Financing these policies through appropriate ministries could lead to significant savings in the health service and have an impact on social inequalities. Moreover, these policies would have a ripple effect on climate change, as the same risk factors that affect chronic diseases are also agents of climate change.
THE ROLE OF HEALTHCARE PROFESSIONALS
While interventions to reduce air pollution and combat climate change typically fall outside the realm of clinical practice, healthcare professionals play a crucial role:
Identifying individuals highly susceptible to cardiac events attributable to pollution
Educating patients about the health impacts of climate change
Promoting sustainable lifestyle choices
General practitioners and paediatricians, in particular, need to be trained on these issues to perform an important educational function for the entire population through interaction with individual patients.
CHALLENGES FOR HEALTHCARE SYSTEMS
ADAPTING TO NEW HEALTH DEMANDS
The Italian healthcare system, despite its challenges (such as doctor shortages, insufficient healthcare personnel, and regional disparities in care delivery), remains one of the best in the world. However, climate change will make its management more challenging.
INTERSECTORAL POLICIES FOR HEALTH AND CLIMATE
The fundamental idea is that by acting with inter-sectoral policies in various environmental sectors, it is possible to simultaneously mitigate climate change and prevent many diseases. While the impact of climate change mitigation is long-term and global (thus not easily perceptible to the population), the health impact is short-term and geographically proximate, making it more easily perceived by the populations involved.
THE IMPORTANCE OF MEDICAL EDUCATION
The role of doctors will be increasingly important in identifying individuals highly susceptible to cardiac events attributable to pollution and exposed to high levels of air pollution. It will be crucial for general practitioners and paediatricians to be trained on these issues to perform an important educational function for the entire population through interaction with individual patients.
