Air Pollution In Columbia: Causes And Concerns

Air pollution is a pressing issue in Colombia, causing about 15,000 deaths every year, with outdoor pollution being responsible for 8,000 of these. Household air pollution, largely caused by burning wood and solid fuels for cooking and heating, accounts for 7,000 deaths, predominantly in rural areas. While the air in Colombian cities has become cleaner in recent years, it still does not meet the WHO's interim air quality standard of 15µg/m3. To address this, Colombia has launched initiatives such as the Biodivercities Alliance for a Better Air, aiming to improve air quality through nature-based solutions.

Household air pollution

The use of solid fuels, such as wood and coal, for cooking and heating is a significant contributor to household air pollution in Colombia. In rural areas, where access to alternative fuels may be limited, burning these solid fuels releases harmful particles into the air. These particles, known as PM2.5, are less than 2.5 thousandths of a millimetre across and can penetrate deep into the lungs. Over 6 million Colombians, particularly in the Caribe, Central, and Pacifica regions, rely on solid fuels for their daily needs. As a result, the air pollution levels in these households can be alarmingly high, often exceeding those in urban areas by a significant margin.

To address this issue, it is essential to promote alternative fuels and improved cooking technologies. For instance, transitioning to propane (LPG) as the primary fuel source can significantly reduce pollution levels. While this option may be more expensive, it offers a substantial reduction in disease and death rates associated with household air pollution. Additionally, improved cookstoves that burn less fuel can be a more affordable option, as seen in successful examples from other countries in the region.

Community involvement is crucial in tackling household air pollution. By involving entire communities, consistent pollution reduction can be achieved for all households. Colombia has taken steps to address air pollution by forming alliances such as the Biodivercities Alliance for Better Air, which aims to identify sources of air pollution and develop nature-based solutions. Cities like Montería, which is part of the clean air alliance, are taking proactive measures to improve air quality and reduce their environmental footprint.

While progress has been made, there is still work to be done to improve air quality in Colombia, particularly in rural areas where household air pollution is a pressing concern. By implementing initiatives that provide access to cleaner fuels and technologies, as well as fostering community engagement, Colombia can continue to make strides toward reducing the impact of household air pollution on its citizens' health and well-being.

Industrial and agricultural sources

In British Columbia, industrial sources of air pollution include the upstream oil-and-gas industry, which releases SOx, NOx, and VOCs into the atmosphere. Other industrial sources include coal mining, cement and concrete production, mining and rock quarrying, and aluminium production. Small businesses, such as automotive shops, dry cleaners, and painting operations, also contribute to air pollution through the use of toxic substances such as paints, solvents, and cleaning agents.

In Colombia, industrial sources of air pollution are not explicitly mentioned. However, the country has joined the Biodivercities Alliance for Better Air, which aims to identify sources of air pollution and develop nature-based solutions. The city of Montería, as part of this alliance, has deployed new air quality monitoring units to gather data and inform more effective policies. The transport sector, including vehicles, marine vessels, and aircraft, is a significant contributor to air pollution in Colombia, with Montería estimating that 28% of its emissions come from this sector.

Agricultural sources of air pollution in British Columbia are not specifically mentioned, but it can be assumed that they contribute to the overall air pollution levels, especially in rural areas.

In Colombia, agricultural sources of air pollution are more apparent, particularly in rural communities. The use of wood and other solid fuels for cooking and heating is a significant contributor to household air pollution, which is responsible for about 7,000 deaths in the country each year. This affects mainly rural communities, where solid fuels are relied upon by approximately 6 million Colombians, or half of all rural households. The transition to cleaner fuels, such as propane (LPG), and the adoption of improved cookstoves are recommended to reduce household air pollution and improve health outcomes.

Transport emissions

Vehicle emissions contain harmful pollutants such as carbon monoxide, nitrogen oxides (NOx), and particulate matter, which have detrimental effects on both human health and the environment. These emissions can lead to respiratory and cardiac issues, as well as playing a role in cancer and genetic mutations. The impact of transport emissions is particularly concerning in urban areas, where over 60% of the Colombian population is estimated to breathe air that exceeds the World Health Organization's (WHO) guideline for safe levels of pollutants.

To address this issue, several Colombian cities have taken initiatives to reduce transport emissions and improve air quality. For instance, Montería has constructed 42 kilometers of bike lanes and implemented a public bike rental network with 11,000 users. The city is also developing Colombia's first public river transportation system, which will be partially powered by solar energy and integrated with the public bus system.

While these efforts are a step in the right direction, more comprehensive measures are needed to tackle transport emissions effectively. This includes improving the availability of information on air quality and emissions, as well as implementing policies and regulations to reduce vehicle emissions and encourage the use of alternative modes of transportation.

Furthermore, it is important to involve entire communities in the transition to cleaner energy sources and technologies. For example, providing access to cleaner cooking facilities and improved cookstoves for rural households can significantly reduce household air pollution, which is responsible for a significant number of deaths in Colombia.

Poor air quality monitoring

Air pollution is a pressing issue in Colombia, causing about 15,000 deaths every year, according to a World Bank study. While 8,000 of these are attributed to outdoor pollution, the remaining 7,000 are due to household air pollution, particularly in rural areas. This is primarily caused by cooking and heating with wood and other solid fuels, which release harmful smoke and particles.

To address this issue, Colombia has recognised the importance of improving air quality monitoring to facilitate more aggressive, evidence-based solutions. As a result, the country launched the Biodivercities Alliance for Better Air in July, aiming to help 11 urban settlements identify sources of air pollution and develop nature-based solutions. This initiative underscores the need for data-driven decisions, as emphasised by Colombia's Minister of Environment and Sustainable Development, Carlos Correa Escaf.

One of the key challenges in Colombia's efforts to improve air quality is the lack of a robust air quality monitoring system. The current system struggles to gather the data required to inform and implement more effective policies. Recognising this gap, the Biodivercities Alliance plans to deploy two new air quality monitoring units, including one focused on vehicle emissions, which contribute significantly to air pollution.

Montería, one of the 11 Colombian cities in the alliance, has already taken significant steps towards reducing its environmental footprint. The city has constructed 42 kilometres of bike lanes, introduced a public bike rental network, and is developing Colombia's first public river transportation system, powered partly by solar energy. These initiatives not only reduce vehicle emissions but also provide sustainable alternatives for transport.

While Colombia's air quality has improved in recent years, particularly in cities, more needs to be done to meet the World Health Organization's (WHO) interim air quality standard of 15µg/m3. Achieving this standard in rural areas, where solid fuel use is prevalent, would be more expensive than investing in cleaner cooking facilities for these households. Therefore, a comprehensive approach involving entire communities is necessary to reduce pollution for all households.

Environmental damage

Air pollution in Colombia has severe environmental implications. According to a World Bank study, air pollution kills 15,000 Colombians annually, with 7,000 of those deaths attributed to household air pollution caused by cooking and heating with wood and other solid fuels. This issue predominantly affects rural communities, where solid fuel usage is more prevalent, and the lack of access to cleaner cooking technologies exacerbates the problem.

The environmental costs linked to atmospheric pollution in Colombia have been significant, nearly doubling between 2009 and 2015. The country has recognized the need to address this problem and has taken steps towards improving air quality. Colombia's Minister of Environment and Sustainable Development, Carlos Correa Escaf, emphasized the importance of data-driven decisions in reducing air pollution. As a result, the Biodivercities Alliance for Better Air was launched to help 11 urban settlements identify sources of air pollution and develop nature-based solutions.

One of the key environmental challenges in Colombia is the extensive use of solid fuels, such as wood, for cooking and heating, particularly in rural areas. This practice releases harmful pollutants into the atmosphere, including particulate matter and toxic substances. The most dangerous of these airborne particles are known as PM2.5, which are tiny particulates that can penetrate deep into the lungs and cause serious health issues.

To mitigate environmental damage, Colombia has been working with nature to combat air pollution. Cities like Montería, which is part of the Biodivercities Alliance, have taken steps to reduce emissions from the transport sector, which accounts for an estimated 28% of the city's emissions. The city has constructed 42 kilometers of bike lanes, introduced a public bike rental network, and is developing Colombia's first public river transportation system, powered partly by solar energy. These initiatives aim to reduce emissions and promote sustainable practices.

Additionally, Colombia is focusing on improving air quality monitoring systems to facilitate more aggressive, evidence-based efforts to tackle air pollution. The deployment of new air quality monitoring units will enable officials to identify and address specific sources of pollution, such as vehicle emissions, industrial activities, and agricultural practices. By strengthening the monitoring network, Colombia will be better equipped to implement corrective, preventive, and mitigation measures to reduce environmental damage caused by air pollution.
