The Effects of WildfiresThe effects of wildfires are destructive, deadly and devastating. Additionally, they are becoming increasingly frequent. From the west coast of the United States to Australia and Russia, wildfires are spreading like never before, wreaking havoc and adding unparalleled burden to the countries’ poor.

The Effects of Wildfires

Wildfires burden society by depleting resources, burdening the economies and impacting citizens’ health. Wildfires force the evacuation of people and often destroy homes and valuables. The University of Oregon Scholars Bank states that a person needs an income of twice the poverty line to be fully capable of protecting oneself, family and assets from fires. Thus, these fires have a disproportionate effect on the poor.

Wildfires Cause Depletion of Resources

One way in which wildfires are destructive is the depletion of resources. The burning of forests destroys properties, trees, vegetation and wildlife. Wildfires often strip families of everything they own in a matter of minutes.

In addition, these fires deplete not only air quality but water quality as well. As wildfires burn, they contaminate the water in streams, lakes and reservoirs which limits access to clean water. Thus, the affected area’s drinking water and food supply are not usable. Limited food and water supplies make it harder for the poor to live.

Wildfires Cause a Decrease in Economic Stability

Wildfires take a large toll on an affected areas’ economic security by causing economies to close. As a result of closing the economy, tourism decreases. The effects of wildfires make areas untravellable as they pose a massive threat to people and destroy forests and hiking trails that often draw tourists. In addition, the economy slowed due to the destruction of resources.

This lack of tourism and loss of resources cause loss of income in affected economies. So, as income from tourism decreases, the number of available low-paying service industry jobs decreases as well. This causes those already living on or below the poverty line to face greater financial hardships as hours and jobs are limited. Furthermore, as fires destroy forests and trees, jobs in the logging or wood chipping industries run scarce.

Wildfires Cause Strain on Human Health

Furthermore, wildfires pose a great threat to human health as their smoke depletes air quality. This can result in reduced lung function, bronchitis, heart failure and asthma among other things. The effects of wildfires on mental and physical health are long-lasting. These effects on health disproportionately affect the poor as they often have limited access to affordable healthcare.

The Increase in Wildfires Worldwide

Wildfires know no bounds and have begun to spread with increased frequency to places that have little to no previous experience with them. Siberia, a tundra that has had limited prior experience with fires, is now struggling to put out a fire that has burned upwards of 6.5 million acres. 

Similarly, in 2020, Australia suffered devastating wildfires that burned 44.5 million acres and killed upwards of 30 people. It killed large amounts of wildlife and devastated their environment. Likewise, Australians are feeling the effects of wildfires in Australia today. The Australian government did little to curtail the devastation of wildfires which led to countless protests by citizens.

The Good News

The devastating effects of wildfires worldwide are far from gone. However, through the increase in aid and wildfire-related programs, the goal to limit drastic spreads and devastation is possible.

The United States developed many fire-related programs that created job opportunities focused on research, fighting and prevention methods and landscape rehabilitation. These programs aim to limit the level of devastation associated with wildfires. Additionally, the USAID also provided humanitarian support to Australia throughout its 2020 wildfires.

With increased research and fire-related programs in addition to global support during times of active burns, the devastating impacts of wildfires can reduce. Thus, they will lower the impacts on communities and preventing an increased burden on the poor.

Air Quality
The COVID-19 pandemic has renewed interest in air quality as lockdowns and public health restrictions have led to improved quality in many areas. Additionally, research has found a link between poor air quality and poor COVID-19 outcomes. The decline in pollution will be only temporary, and in many areas was actually smaller than scientists anticipated.

The impacts of poor air quality on global health beyond COVID-19 are numerous. However, curbing emissions and improving quality where it is already poor are huge undertakings. Nonetheless, looking at those living in urban areas where quality is monitored, more than 80% of people are experiencing air pollution in excess of the limits suggested by the World Health Organization (WHO). This makes air quality a pivotal global health issue.

Another important factor in addressing this issue is the distribution of the negative effects of poor air quality. In other words, the development of any program or policy interventions ought to consider the inequitable distribution of those effects. Research in the United States and the United Kingdom indicates that while wealthier people tend to be responsible for the majority of air pollutants, those living in impoverished areas disproportionately experience the harmful effects of those pollutants.

A. What Compromises Air Quality

There are two main categories of air pollutants: those naturally occurring and those human-made. While dust storms and wildfires can introduce harmful particulate matter, there are also numerous sources of pollution driven by human activities. These include automobiles, certain types of power plants, oil refineries and more. In addition to particulate matter, other pollutants that adversely affect health include sulfur dioxide, nitrogen dioxide and ozone.

Finding new yet affordable ways to decrease the pollutants we release into the air is challenging but not insurmountable. Putting this into perspective, 90% of people around the world are breathing unclean air according to WHO guidelines.

B. What Poor Quality Air Does to Our Health

Beyond the link between air pollution and poor COVID-19 outcomes, research also shows the negative impact air pollution has on the risk of stroke and heart disease, certain types of cancer, lung infections and diseases and even mental health. Furthermore, both air quality and environmental quality tend to be worse in areas of the world already comparatively disadvantaged.

According to research on the effectiveness of European climate and pollution policies, the number of people prematurely dying after exposure to fine particulate matter pollution decreased by approximately 60,000 between 2018 and 2019. Better yet, between 2010 and 2020, there was a 54% drop in premature deaths attributable to nitrogen dioxide pollution. Despite these positive outcomes, they also demonstrate the extent of the damage airborne pollutants can do to human health.

C. What Has Proven Successful in Protecting Air Quality

Like health policy progress, innovations in air quality programs and policies often start at the local government level. According to the Environmental Defense Fund (EDF), cities around the world are implementing ultra-low and zero-emission urban access zones, deploying hundreds of thousands of electric buses, and learning from their own successes in moving to clean municipal transportation in order to teach other cities to do the same.

The EDF notes the importance of gathering detailed data on air quality. This data allows organizations to identify communities disproportionately affected by pollution and develop targeted approaches to protecting and improving air quality. This type of data can help localities not only measure levels of pollutants over time but pinpoint hotspots. Hotspots include, for example, those caused by construction sites and manufacturing facilities. The need for this type of data is worldwide, but developing nations are in particular need of the tools necessary for thorough air quality monitoring.

Highlighting the successes experienced in air pollutant reduction efforts in wealthier counties may seem counterintuitive given the importance of addressing inequalities across the world. Still, they also represent numerous lessons for developing cities and countries to learn. The negative experiences of areas already developed have yielded data, technology and sample policies from which leaders worldwide can draw. Moving forward, it is essential that organizations and leaders around the world prioritize improving air quality.

Childhood Pneumonia
One of the most common diseases globally, pneumonia can be a silent killer when it infects children under 5. In the developing world, rates of childhood pneumonia cases and deaths are still high despite decreasing in other childhood diseases. However, due to new research and outreach programs to aid developing countries, those numbers may soon fall.

10 Facts About Childhood Pneumonia

  1. Various sources cause the disease. Unlike many other diseases that come from a single source, pneumonia is the name for the lungs’ acute response to an airborne pathogen. While pneumonia can develop from bacteria, viruses or fungi, the most common cause for children is the bacteria S. pneumoniae. The bacteria typically live in the lungs without harming the body, but the body develops pneumonia to kill the bacteria when it begins to spread.
  2. Childhood pneumonia mainly infects children under the age of 5. While people of all ages can develop pneumonia, children under the age of 5 are especially susceptible to the infection. Since their immune systems are not fully developed, their bodies are more likely to trigger a response to a foreign agent’s presence in the respiratory system, leading to pneumonia. These infection rates only increase in developing countries, where children are more likely to be born either malnourished or with a disease that they acquired in utero such as HIV.
  3. Pneumonia is a leading cause of death in children. Although pneumonia is often easy to treat and cure in developed countries, it can be fatal in developing countries. According to the United Nation’s Children’s Fund (UNICEF), childhood pneumonia kills over 800,000 children each year in comparison to 437,000 from diarrhea and 272,000 from malaria. These deaths are typically in children who are malnourished or have other conditions such as HIV that impair the immune system.
  4. South Asia has the greatest incidence of childhood pneumonia. Out of every 100,000 children in South Asia, approximately 25,000 will develop pneumonia each year. However, the majority of these cases — approximately 36% — occur in India. Studies looking into the potential causes for the increased number of cases have found that overcrowding in housing with inadequate ventilation allowed the disease to spread among families. Without effective airflow, children in those households continue to breathe in potentially infected air, increasing their chances of developing pneumonia.
  5. Air pollution increases pneumonia rates. Although a child needs to have exposure to the biological cause of pneumonia to develop the disease, certain environmental factors can increase infection likelihood. In India, a country with one of the worst-rated air qualities in the world, particles of smoke and other forms of pollution in the air weaken lungs when inhaled, making it more likely for a young child to develop pneumonia. These conditions of outdoor air pollution causes approximately 17.5% of all pneumonia deaths in the developing world.
  6. The disease is treatable. With antibiotics or antifungals (depending on the cause), children with pneumonia can recover from the disease. However, this treatment is dependent on the resources available in the country where the child lives. In developing countries such as Nigeria — the African country with the highest pneumonia rates in children — only one in three children with pneumonia symptoms can receive treatment due to the lack of available medicines and other medical resources.
  7. Some are producing vaccines. Although vaccines cannot treat viral pneumonia, they are still an important asset in preventing it. However, most of the produced vaccines are only available in developed countries where doctors recommend them for children under 5. In developing countries, nearly 10 million children are unvaccinated. Through the World Health Organization (WHO), many countries have received vaccines, although there has been great variation between regions of the world. While WHO’s South-East Asian Region has 89% coverage, its Western Pacific region only has 24% coverage.
  8. Less progress has occurred regarding childhood pneumonia. While research on pneumonia as a whole has increased over the past decade, there has been much less progress on childhood pneumonia in comparison to other childhood diseases. Since 2000, deaths for those under 5 from pneumonia have decreased by 54%, while deaths from diarrhea have decreased by 64% and are currently half the number of childhood pneumonia deaths.
  9. Large organizations are helping. Among other large, international organizations, the Gates Foundation has taken efforts to reduce childhood pneumonia rates in developing countries. One of its main methods is the continued distribution of vaccines to children and families in South Asian and Sub-Saharan Africa, specifically India and Nigeria. So far, the organization has sent vaccines to over 37 countries in those regions of the world, slowing transmission and infection rates in those areas.
  10. Rates will continue to drop in the future. Although the number of childhood pneumonia cases each year have not dropped as much as other diseases, long-term progress is still ongoing. If the current level of progress toward eradicating the disease continues, UNICEF predicts that it will save 5.9 million children. At the same time, if resources towards the effort increase, that number will increase to nearly 10 million.

UNICEF and WHO do not expect to meet their goal of eradicating childhood pneumonia until 2030. However, the progress they and many others are currently initiating is making a difference. Soon, pneumonia will become an extinct disease in the developing world so that it will never harm another child.

Air Pollution in Nepal's Kathmandu ValleyLocated in a bowl-shaped region enclosed by four mountain ranges, the Kathmandu Valley is Nepal’s most populous and developed metropolitan area. However, with the valley’s population density, level of industrialization and geographic location, a host of problems afflicts the region. In recent years, the international and domestic communities have paid increasing attention to the worsening issue of air pollution in Nepal’s Kathmandu Valley. In Nepal, air contains five times more pollutants than the amount considered safe by the World Health Organization (WHO); the air in the Kathmandu Valley contains ten times the pollutant concentration set forth by WHO guidelines.

Causes of Air Pollution

The Urban Health Initiative (UHI), an on-the-ground pilot program initiated by the WHO, has identified four primary sources of air pollution worldwide:

  • Solid waste
  • Transport
  • Industry/brick kilns
  • Household energy sectors

The geographical location of the Kathmandu Valley exacerbates all four sources of pollution. Since tall mountain ranges enclose the region, the valley does not get enough wind to disperse air pollutants. Furthermore, Nepal’s location between China and India means that the contaminants from both countries flood into Nepal and vice versa.

Effects of Air Pollution in Nepal’s Kathmandu Valley

Air pollution has had a massive impact on Nepalese people. Every year, 35,000 people in Nepal die from illnesses related to air contaminants. Air pollution frequently causes osteoporosis, heart attacks, dementia and kidney diseases. Furthermore, the life expectancy in the Kathmandu Valley is four years less than that of other Nepalese regions.

While the government has taken little action to reduce the region’s concentration of air pollutants, the Nepalese people have taken matters into their own hands. People have started to wear face masks day-to-day, cancel outdoor activities and frequently monitor air pollution levels. Although individuals have shown an admirable degree of agency in protecting themselves, the Nepalese government must take greater action to reduce the risk of air contaminants for its people.

Action Items So Far

To address air pollution in Nepal’s Kathmandu Valley, the Nepalese government has released a National Plan for Electric Mobility (NPEM) that contains several time-oriented goals. The NPEM includes several objectives: increasing the share of electric vehicles to 20% by the end of 2020, cutting fossil fuel use in the transport sector 50% by 2050 and developing a hydroelectric powered rail network by 2040. The NPEM focuses on pollution caused by transportation, and this emphasis has shown promising results.

Due to the COVID-19 pandemic, automobile use has decreased significantly in Nepal. The air quality index in April 2020 showed a noteworthy improvement compared to April 2019: the air on April 30, 2020, contained about 50% fewer contaminants than the air the year prior. Therefore, the government should be able to achieve significant improvements in air quality by targeting automobile emissions.

Efforts by USAID

In 2015, USAID launched the five-year, nearly $10 billion Nepal Hydropower Development Project (NHDP). With this project, USAID aimed to assist in the development of hydroelectric power services. Nepal has impressive hydroelectric capabilities and, if the country harnesses its full hydroelectric potential, it could even have an energy surplus to export to neighboring countries and gain additional revenue.

Working in tandem with various Nepalese governmental organizations, the NHDP focuses on private sector development and investment in hydroelectricity. By creating viable power services, the NHDP hopes to permanently transform Nepal’s energy sector to include more sustainable sources.

Moving Forward

As Nepal and international organizations improve the country’s air quality, a successful continued response will require cooperation. Given Nepal’s landlocked location, collaboration with other countries such as India and China is also necessary. However, in light of the efforts of the Nepalese government and USAID, Nepal is taking steps in the right direction to improve its air quality for the benefit of everyone in the region—especially those in the vulnerable area of Kathmandu Valley. Ultimately, there is hope to combat air pollution in Nepal’s Kathmandu Valley and protect the health and safety of thousands.

Socioeconomic implications of air pollutionAir pollution is commonly understood as an environmental issue. In the U.S., pollution is most commonly tested using the Air Quality Index. The AQI measures air pollution based upon ground-level ozone, particle pollution, carbon monoxide, sulfur dioxide, and nitrogen dioxide levels. Air pollution causes a number of health risks such as cancer and respiratory infections. In 2016, an estimated 4.2 million people died prematurely due to air pollution. Often, the effects of environmental issues have more consequences for the poor. Thus, concerns stemming from air pollution are not just environmental but also socioeconomic.

Who is affected?

About 90 percent of premature deaths by air pollution occur in low-middle income areas. This issue disproportionately affects lower-income households for many reasons. For one, impoverished homes are often dependent upon energy sources such as coal and wood. The burning of these fossil fuels contaminates the air with carbon dioxide emissions and creates indoor pollution. A lack of finances can also result in the absence of healthcare. Without early treatment, people dealing with infections related to air pollution are more likely to suffer fatal consequences.

Research shows that this disparity supports social discrimination. A study in 2016 reports: “The risk of dying early from long-term exposure to particle pollution was higher in communities with larger African-American populations, lower home values, and lower median income”. Minority groups often face prejudice in places such as employment. On average, a black woman makes 61 cents per dollar earned by a white male counterpart. In sum, minority groups ordinarily earn lower wages. This prohibits them from buying more expensive renewable resources.

The largest effects of air pollution take place in the World Health Organization’s South-East Asia and Western-Pacific regions. These regions are primarily occupied by developing nations. With a lack of financial resources, these countries resort to cheap and environmentally unsustainable practices. For example, the slash-and-burn technique is a method used by farmers and large corporations. This technique involves clearing land with intentional fires, which raises carbon dioxide levels.

What are the implications?

When considering the socioeconomic implications of air pollution, it is important to note all of the key facts. Here are a few things to consider:

  • The WHO has declared air pollution as the number one health hazard caused by environmental degradation. Air pollution can cause ischaemic heart disease, strokes, chronic obstructive pulmonary disease, and lung cancer.
  • Worldwide, 1 in 8 people dies due to the effects of air pollution. In 2018, 7 million people passed away because of infections relating to air quality.

Who is helping?

Air pollution should not be overlooked as a serious issue. Fortunately, in recent years there has been a significant movement to combat poor air quality. For example, China has a reputation for being heavily polluted. However, in 2015, the Chinese government was the world’s lead investor in renewable energy. The government invested $26.7 billion in renewable resources, which was twice the amount that the U.S. invested that same year. Furthermore, between the years 2010 and 2015, particle pollution levels in China decreased by 17 percent.

Organizations such as Greenpeace have advocated for better policies surrounding environmental degradation. In 2013, the Chinese government released the Clean Air Action Plan which set forth the initial progress in combating air pollution. Nevertheless, in 2017, Greenpeace recorded that while particle pollution levels continued to decrease, progress had significantly declined. Greenpeace is now urging the government to produce a new plan to further challenge air pollutants.

Air pollution is harmful to the global ecosystem but it also has a profound impact on society. In order to fully understand the consequences of this issue, one must consider the ways in which environmental degradation targets specific groups. The contamination of the environment, or more specifically the air, often affects minorities and the poorest people. Thus, air pollution should be a top priority not only for environmentalists but also for social activists. Luckily, governments are already seeking plans to prevent the outcome of air pollution. By contributing to organizations such as Greenpeace, everyone can advocate for better policies and regulations against the socioeconomic implications of air pollution.

Malaria. HIV/AIDS. Tuberculosis. One of these must be the biggest cause of death in the developing world, right?

Wrong. It is pollution, not diseases, that causes the most deaths in developing countries. 8.4 million people’s lives are claimed each year by varying kinds of pollution. That is three times more deaths than those caused by malaria and four times more than those caused by HIV/AIDS.

India and Africa are areas where there are particularly serious problems. India, not China, is home to the world’s most polluted city: Delhi. The number of PM 2.5 particles, the world’s most dangerous pollution, capable of penetrating the lung and therefore entering straight into the bloodstreams of millions, reached 21 times the recommended limit recently.

These levels are twice as toxic as those in Beijing, the accepted pollution capital of the world. The pollution in India accounts for 1.3 million deaths a year. It also cuts 660 million lives short by three years. Three years off a life simply because of where a person is born or happens to live.

Pollution is also a danger in Africa, where Malaria and HIV/AIDS often take the headlines as leading killers on the continent. Gaborone, Botswana, ranks eighth in particulate pollution among cities that provided information about their pollution levels.

Besides outdoor pollution is an issue, there is also the problem of indoor pollution in both Africa and India. This is generated mostly from cooking with wood and other sooty fuels that clog up the air. Even more worrisome is the fact that Africa could account for at least half of the world’s population by 2030, due to its increased mining, oil, and biofuel industries that will go along with a rise in urbanization. Regulations are lax towards both indoor pollutants as well as corporate ones.

Never fear, however. New wearable pollution-sensing technology is on the way to save the day, or at least improve the situation somewhat. TZOA is producing a small gadget capable of informing wearers about the air they breathe. “TZOA uses internal sensors to measure your air quality, temperature, humidity, atmospheric pressure, ambient light and UV (sun) exposure all in one wearable device.”

The device can hook up to an app on a phone to give air readings. It is not alone in the small pollution-sensing technology department. A device that doubles for a keychain, called Clarity, can perform a similar task to the TZOA. Clarity tracks “personal exposure to air pollution via a smartphone app,” just like the TZOA.

While these technologically advanced gizmos cannot reduce the drastic levels of pollution around the globe that are killing millions, what they can do is help provide data where it is lacking in areas where pollution is prevalent. Data is often not available, or not provided for some of the areas with the worst pollution.

The wearables also have the potential to raise awareness of the severity of the issue. Empowering those in the thick of the worst conditions has the potential to make the severity of the situation clearer to both governments and ordinary people. Armed with this information, both could take action because of the data provided by devices like TZOA and Clarity.

Shanhai_Smog_Creating_Health_Concerns
Officials in Shanghai are holding their order that children and elderly persons remain inside their homes, since the outdoor smog levels reached dangerously high levels on Friday December 6.

The Chinese government ordered a stop to construction and for factories to cut production following the warning. Flights were delayed and cars were ordered off the roads due the thick haze reducing visibility to 150 feet in certain areas. The city’s Air Quality Index rose above 500, “beyond index” for the first time in history.

The Air Quality Index is a scale from 0-500; a warning for people to stay indoors is typically given when the index surpasses 200. Two days after the government issued warning, the air was still considered “heavily polluted” by a local monitoring center, with an index rating of 238.

Smog is formed when mono-nitrogen oxides and volatile organic compounds react in the presence of sunlight. The main smog-causing sources are stationary industrial emissions and automobile exhaust. China’s rapidly increasing factory production, coal-burning plants and high use of automobiles are exceeding the few government regulations that are attempting to reduce air pollutants, creating a serious health issue for Shanghai’s citizens.

Shanghai’s dangerous particulate matter (PM) was 14 times higher than the World Health Organization’s recommended daily exposure. In circumstances such as these, health is the main concern. According to an article from National Public Radio, a local resident reported having a headache, coughing, and difficulty breathing while on her way to work.

PM is a complex combination of solid and liquid particles of organic and inorganic substances suspended in the air, affecting more people than any other pollutant according to the WHO. When inhaled, PM may interfere with gas exchange inside the lungs, causing cardiovascular and respiratory diseases after chronic exposure. Outdoor air pollution contributes to an estimated 1.3 million deaths per year, with those in middle-income countries disproportionately suffering.
