Climate change is reshaping the world in many ways, and Latin America is experiencing some of the most severe impacts. While much of the focus has been on rising temperatures and environmental degradation, less attention has been given to the toll it is taking on the region’s workforce. From heat stress to air pollution, workers across various sectors are increasingly exposed to health risks that threaten both their livelihoods and well-being. This article explores how climate change is amplifying these risks, the most affected sectors, and the actions being taken to mitigate these challenges.

Rising Temperatures and Heat Stress

One of the most immediate and dangerous impacts of climate change is the increase in temperatures across Latin America. In 2023, the region recorded its highest average temperatures, with many areas experiencing heatwaves. Workers, especially those in outdoor sectors like agriculture and construction, are bearing the brunt of this heat. Excessive heat exposure can lead to conditions like heat exhaustion and heat stroke, both of which can be fatal if untreated.

Studies show that workers in agriculture are particularly vulnerable, with a sharp rise in heat-related illnesses and deaths. Maintaining a stable body temperature of around 37°C is essential for normal bodily functions, but when temperatures exceed 38°C, workers experience impaired cognitive and physical abilities, pushing them into what is known as “heat exhaustion.” At 40.6°C, workers are at risk of heat stroke, organ damage, and even death.

The International Labour Organization (ILO) estimates that by 2030, heat stress could result in the loss of 2.5 million outdoor jobs in Latin America. This will not only affect productivity but also significantly reduce income in sectors where workers already face precarious conditions.

Air Pollution: A Growing Concern

In addition to heat, climate change is exacerbating air pollution across Latin America, especially in cities and industrial areas. Drier, hotter conditions intensify pollution levels, while more frequent wildfires, fueled by rising temperatures, release harmful emissions into the air. Outdoor workers, such as those in agriculture, construction, and street vendors, are especially exposed to pollutants like ozone and particulate matter, which can cause respiratory problems, cardiovascular diseases, and other long-term health issues.

The combination of heat and air pollution creates a dangerous “cocktail” of health risks. For instance, when high temperatures combine with poor air quality, workers face increased risks of lung damage, heat exhaustion, and respiratory distress, further amplifying the health burden.

Vector-Borne Diseases on the Rise

Another emerging health risk for Latin American workers, especially those in rural and tropical areas, is the spread of vector-borne diseases such as dengue fever, malaria, and Zika virus. Climate change is altering the distribution and seasonality of these diseases, making outbreaks more frequent and widespread.

Outdoor workers in agriculture and construction are particularly exposed to mosquito-borne diseases, and record outbreaks of dengue have already been reported in parts of South America. Rising temperatures and changes in rainfall patterns create ideal conditions for mosquito populations to thrive, putting millions of workers at risk of contracting these life-threatening diseases.

Extreme Weather Events: A Threat to Safety

Latin America is no stranger to extreme weather events like hurricanes, floods, and wildfires, but these have become more frequent and intense due to climate change. Workers in sectors such as emergency services, construction, and agriculture face heightened risks when responding to or working through these disasters.

For emergency responders like firefighters and healthcare workers, extreme weather events increase the likelihood of hazardous working conditions, including exposure to biohazards, chemical spills, and traumatic injuries. Meanwhile, agricultural workers and laborers in construction sites face dangerous conditions during floods and hurricanes, which disrupt work and increase risks of injury.

The Most Affected Sectors

The sectors hardest hit by climate-related health hazards are agriculture, construction, and tourism. These industries rely heavily on outdoor labor, leaving workers highly vulnerable to heat stress, extreme weather, and air pollution. In agriculture, rising temperatures are not only making it harder for workers to maintain normal working hours but are also increasing the need for pesticide use due to soil degradation. This leads to greater exposure to harmful chemicals, further endangering worker health.

Construction workers, too, are facing mounting risks. As heatwaves intensify, working conditions become more dangerous, especially for those working in poorly ventilated or confined spaces. The ILO reports that the productivity of outdoor workers in Latin America is expected to decline by 1% for every 1°C rise in temperature.

Government Response and Mitigation Efforts

Governments and organizations across Latin America are gradually recognizing the growing health risks posed by climate change, but their responses have been varied and fragmented. In some countries, policies have been introduced to protect workers from excessive heat. For example, Brazil has implemented guidelines that require work to be halted when temperatures exceed certain thresholds, and Costa Rica mandates that employers provide hydration and shaded rest areas for outdoor workers.

In Chile, employers are required to monitor solar ultraviolet radiation levels and provide protective gear to workers. Legislation is also being implemented in various countries to prevent pesticide overuse and reduce the risk of vector-borne diseases by limiting working hours during the hottest parts of the day.

Despite these efforts, many of these policies are still in their early stages, and a more unified regional approach is needed to effectively address the full scope of climate-related health risks.

The Future: Job Losses and a Green Economy

While climate change poses significant health hazards, it is also expected to reshape the job market in Latin America. The transition to a low-carbon economy will lead to job losses in sectors like fossil fuels and certain forms of agriculture, but it will also create new opportunities in areas such as renewable energy, forestry, and environmental conservation.

A 2020 report by the ILO and Inter-American Development Bank projected that while 7.5 million jobs may be lost in the region by 2030, another 22.5 million new jobs could be created in green industries. However, ensuring that these jobs are accessible to those most affected by climate change, particularly informal and outdoor workers, will require careful planning and policy changes.

Conclusion

Climate change is undeniably raising the stakes for workers in Latin America. From extreme heat to air pollution and the spread of diseases, the health hazards are increasing at an alarming rate. While some governments and organizations are beginning to take action, much more needs to be done to protect workers from these escalating risks. As the region looks toward a future shaped by climate change, ensuring the safety, health, and livelihoods of workers must be a top priority.

FAQs

How is climate change affecting workers in Latin America?

Climate change is exposing workers in Latin America to extreme temperatures, air pollution, and an increase in vector-borne diseases. Outdoor workers in sectors like agriculture and construction are particularly vulnerable to heat stress, respiratory problems, and work disruptions caused by extreme weather events.

What are the health risks workers face due to rising temperatures?

Workers, especially those in outdoor environments, face significant risks like heat exhaustion and heat stroke. Prolonged exposure to extreme heat can impair cognitive and physical function, increasing the risk of organ damage, unconsciousness, and even death.

How does air pollution impact worker health in Latin America?

Climate change exacerbates air pollution, leading to higher levels of harmful pollutants such as ozone and particulate matter. This exposes outdoor workers to respiratory and cardiovascular diseases, further compounding the health risks posed by heat stress.

What sectors are most affected by climate change in Latin America?

The agriculture, construction, and tourism sectors are among the hardest hit. Workers in these industries are more exposed to outdoor conditions and face increasing threats from heat, air pollution, and extreme weather events like floods, hurricanes, and wildfires.
