China's Rural Pollution Crisis: Impact And Challenges

Rural China is affected by pollution in several ways. Pollution in rural China is often as rife as in its urban industrial heartlands. Mining companies often ride roughshod over environmental laws, and cottage industries dismantling electronic waste create their own health hazards. In some cases, the Chinese government has only recently begun to acknowledge the problem of indoor air pollution in rural areas.

In Baocun, a Yunnan village surrounded by phosphorus mining and fertiliser plants, nose and throat infections, hand and feet swelling, and joint pain (possibly the early stages of fluorosis) were regarded as normal. When asked about their health, villagers almost always neglected to mention such conditions. They often said that the body can get used to pollution.

In Guiyu, Guangdong, a hotspot for trading and processing electronic waste, stinging eyes and headaches were common when plastics were burnt. The smell was sometimes overpowering.

In Qiancun, a heavily polluted lead and zinc mining village in western Hunan, residents were more cautious about suggesting that pollution affected their environment and their bodies when officials were around. When they were alone, they sometimes went to the other extreme, to draw attention to their suffering. Some asked for help in obtaining redress from higher levels of government.

Under Xi Jinping, there have been increasing efforts by the central leadership to show a strong commitment to curbing pollution. However, problems in many areas remain under the radar. Poorer, often rural, localities are more likely to accept polluting firms in exchange for tax revenue and employment.

Regulations have improved, but economic incentives to accept polluting activities in poor areas are still strong. Enforcement is still a huge issue.

Air pollution in rural China is caused by the burning of coal and biomass in homes, which has been linked to respiratory and heart ailments

The burning of solid fuels, such as coal and biomass, in simple combustion devices such as household cooking and heating stoves, results in substantial emissions of pollutants. This is due to the difficulty of completely premixing the fuel and air during burning, which is easily done with liquid and gaseous fuels. As a result, a significant fraction of the fuel carbon is converted into products of incomplete combustion (PICs), which include carbon monoxide, sulfur dioxide, and particulate matter.

The combustion of coal and biomass releases toxic constituents, such as polycyclic aromatic hydrocarbons (PAHs), which have been linked to various health issues. PAHs are formed during the incomplete combustion of all carbon-based fuels, and their presence in the particle phase makes them particularly harmful to human health.

In rural China, the burning of solid fuels for cooking and heating is widespread, with over 60% of the population still relying on these fuels. This has led to high levels of indoor air pollution, with pollutant levels generally exceeding China's indoor air quality standards.

The health effects of air pollution from solid fuel combustion in rural China include respiratory illnesses, lung cancer, chronic obstructive pulmonary disease, weakening of the immune system, and reduction in lung function. Arsenic poisoning and fluorosis, resulting from the use of "poisonous" coal, have also been observed in certain regions.

Interventions to reduce indoor air pollution from solid fuel combustion are available, such as improved stoves with chimneys or more complex bioenergy programs. However, these interventions require coordinated support from the government and commercial sector to be successful.

Rural residents in China are often unaware of the health risks posed by indoor air pollution, and there is a crisis of ignorance in these areas

In addition, an attitudinal study of Anqing suggested that, despite widespread health problems in the area, residents showed little concern for the environment broadly, and indoor air quality specifically. 63% of the 244 residents surveyed were unfamiliar with the term "environmental protection"; 58% would throw litter aside rather than search for a proper receptacle; 70% felt biomass cooking posed no harm to their health; and, nearly 65% of respondents saw nothing wrong with burning fields.

The Chinese government has been trying to address this issue by implementing the National Improved Stove Program (NISP), which has proven to improve indoor air quality in rural areas. However, there is still a lack of awareness among rural residents about the health risks associated with indoor air pollution, and more efforts are needed to educate and raise awareness about the dangers of indoor air pollution in these areas.

The Chinese government has implemented the National Improved Stove Program (NISP) to encourage the use of more energy-efficient stoves, with some success

China's economic boom has led to severe environmental pollution, which has had a significant impact on the health of its citizens. Air pollution, in particular, has been identified as a leading cause of mortality, with an estimated 800,000 premature deaths attributed to it annually.

To address this issue, the Chinese government, in collaboration with the World Bank, implemented the National Improved Stove Program (NISP) in the 1980s and 1990s. This program aimed to promote the use of more energy-efficient stoves, specifically targeting rural households that relied heavily on solid fuels such as coal and biomass for cooking and heating. The NISP was a remarkable success, distributing 180 million improved stoves across the country. This initiative not only reduced air pollution but also contributed to China's strategy to promote energy conservation, carbon emission reduction, and the adoption of green energy in villages.

The impact of the NISP extended beyond air quality improvements. For instance, the transition to cleaner energy sources in rural areas resulted in a significant reduction in the number of premature deaths. It is estimated that the program prevented approximately 130,000 premature deaths associated with exposure to particulate matter (PM2.5) from solid fuel combustion. Additionally, the shift away from solid fuels led to a decrease in the climate forcing associated with this sector, contributing to China's efforts to address climate change.

Despite the success of the NISP, challenges remain. Solid fuel combustion still contributes significantly to air pollution, particularly in rural areas. This is partly due to the slow transition away from solid fuels for heating, as cleaner alternatives are often more costly and inaccessible to low-income households. As a result, solid fuel combustion continues to impact both rural and urban air quality, with higher contributions during the winter heating season in northern China.

To build on the success of the NISP and address remaining challenges, China launched the "China Clean Stove Initiative" in 2012, in collaboration with the World Bank. This initiative aims to accelerate access to clean and efficient stoves for all citizens by 2030, with a particular focus on poor, rural households.

The impact of stoves on health was expected, but one study found that residents showed little concern for the environment or indoor air quality

The use of traditional stoves in rural China has been linked to premature deaths and climate change. According to research published in Nature Sustainability, many Chinese homes continue to use traditional coal and wood-burning stoves despite the health risks and their contribution to climate change. Air pollution from these stoves contributed to approximately 2.8 million premature deaths globally in 2017. While 95% of households in the study had started using clean energy for cooking, only 35% had completely stopped using traditional stoves for cooking, and 17% for heating.

The China Clean Stove Initiative, launched in 2012 by the World Bank and China's Ministry of Agriculture, aims to bring clean cooking and heating solutions to all citizens by 2030. However, the initiative has faced challenges due to the reluctance of many households to give up traditional stoves. A study by King's College London and McGill University found that a better understanding of the reasons behind this reluctance is needed for policies encouraging a shift towards clean energy to succeed.

One study found that rural residents in China lack awareness of the impacts of environmental pollution on their health. The study, which focused on the attitudes of urban and rural residents towards environmental pollution and its health effects, found that the rates of urban residents who perceived air, water, garbage, and noise pollution were higher than those of their rural counterparts. While urban residents perceived pollution to have a negative impact on their health, none of the perceived pollution types had a significant impact on rural residents' health. This disparity in awareness may create risks and vulnerabilities within the rural environment and livelihood of these residents.

The impact of stoves on health is evident, with studies showing that childhood asthma and adult respiratory disease are positively associated with coal use and negatively associated with improved stoves and good stove maintenance. However, one study found that residents showed little concern for the environment or indoor air quality, indicating a need for education and awareness campaigns to highlight the health and environmental risks associated with traditional stove use.

There is a significant urban-rural differentiation mechanism for environmental health effects, with gender, household size, travel, and physical activity having insignificant effects on the health of the rural population

There is a significant urban-rural differentiation mechanism for environmental health effects in China. This is due to the fact that the rates of urban residents who perceive air pollution, water pollution, garbage pollution, and noise pollution are higher than those of their rural counterparts. This is because urban residents perceive more environmental pollution than their rural counterparts.

The four types of perceived environmental pollution all had insignificant effects on rural residents' health. This is because rural residents lack awareness of the impacts of environmental pollution on health. This may create risks and vulnerabilities within the rural environment and the livelihood of these residents.

Gender, household size, travel, and physical activity had insignificant effects on the health of the rural population.
