Introduction
Stubble burning is a significant issue in Munshiganj, Bangladesh, which occurs during the potato harvesting season. Despite efforts to educate farmers and provide alternative methods, the burning of stubble continues to increase in the country (Bangladesh Bureau of Statistics, 2020). This practice results in the release of carbon and nitrogen previously stored in the biomass, leading to air pollution and contributing to global warming due to the emission of CO2 (Rembon & MacKenzie, 1997). The burning of crop residue in open fields has become a significant concern for climate change mitigation efforts worldwide and has led to air quality impairment, smog, haze, heatwaves, and different health problems (Raza, et al., 2022). This practice also impacts soil fertility and crop yield, affecting both the environment and the economy.
Epidemiological studies have shown that air quality contamination resulting from stubble burning leads to adverse health impacts, as rice straw is often burnt in the fields, resulting in airborne emissions that are hazardous to human and ecosystem health (Korenga, Liu, & Huand, 2001). The air that we breathe can consist of many contaminants, including ozone (O3), sulfur dioxide (SO2), particulate matter, volatile organic compounds (VOCs), and nitrogen oxides (NOx) (Synnefa, et al., 2003) (Lee, Chan, & Chiu, 1999). These contaminants have specific impacts on human health and the environment (Islam, Hasina, Majumder, Hossain, & R, 2017). Atmospheric PM is of great concern to the public and government agencies because of its significant impact on human health, visibility reduction, agriculture, and atmospheric chemistry (Sarker, Yeasmin, Rahman, & MA, 2018).
This research report aims to explore the causes and effects of stubble burning in Munshiganj, Bangladesh, and to identify alternative solutions to this practice. The study focuses on the perceptions and attitudes of farmers towards stubble burning and the impact of this practice on soil fertility, crop yield, and the environment. The significance of this study lies in its potential to provide insights into the factors that contribute to the practice of stubble burning and to identify more sustainable alternatives. The findings of this study could inform policy decisions and strategies aimed at reducing the negative impact of agriculture on the environment and human health.
Methodology
Research Design: This qualitative case study aimed to investigate the causes of stubble burning in Munshiganj, Bangladesh, and explore ways to raise awareness and prevent the practice.
The central research question for this study is “What causes stubble burning in Munshiganj, and how can awareness be raised to prevent it?” The study was guided by five sub-questions (Creswell, 2018):
- What factors influence farmers in Munshiganj to engage in stubble burning?
- What knowledge do farmers have about the air pollution caused by stubble burning?
- How does stubble burning in Munshiganj contribute to air pollution and other environmental issues?
- What steps can be taken to educate and raise awareness among farmers in Munshiganj about the negative impacts of stubble burning?
- What are alternatives and policies for managing crop residue and addressing stubble burning in Munshiganj?
Participants: The study included a total of 15 participants, comprising six farmers, eight residents, and one government official from the Department of Agriculture. Recruitment was conducted using purposive and snowball sampling techniques to ensure diversity.
Data Collection: Data was collected through semi-structured interviews consisting of 15 questions, which were recorded with participants’ consent and later transcribed for analysis. The average length of the interviews was 10-12 minutes. Additionally, demographic information was collected from participants before conducting the interviews.
Data Analysis: The transcribed data were analyzed using a qualitative content analysis approach (Braun & Clarke, 2006), involving coding, categorizing, and reviewing the data to identify patterns and emerging themes.
Ethical Considerations: The study adhered to ethical guidelines set forth by the American Psychological Association. Informed consent was obtained from all participants, and their anonymity and confidentiality were ensured throughout the study (American Psychological Association, 2017).
Findings
Factors Contributing to Stubble Burning
Several factors contribute to the practice of stubble burning in Munshiganj. Some farmers do not have enough space to store the stubble, leading them to resort to burning the excess materials. Burning unnecessary plants is seen as a way to address issues of pest infestation and manage the cost of straw management. Additionally, some farmers believe that burning the stubble at night reduces the impact of the smoke on people. Finally, there is a perception among some farmers that burning the stubble can have positive effects on soil treatment.
Many farmers in Munshiganj believe that using stubble-burning ash can have a positive impact on the fertility of their land, leading to better crop yields, particularly for vegetables. Several farmers have reported positive results after using the ash in their fields, and some have even found that mixing cow dung with the ash further enhances its benefits for the soil. This traditional practice has been used for generations and is believed to have many beneficial properties for the soil.
According to farmers and agricultural experts, stubble-burning ash can work as a potash supplement for crops. If the soil in cropland has decreased levels of potash, applying the ash can help to recover some of these levels. This traditional practice has been used for generations and is considered by some to be an effective way of supplementing the soil with necessary nutrients.
Agricultural experts suggest that when farmers harvest crops, they often leave behind unnecessary plants, straws, and other debris. These can become breeding grounds for insects, acting as alternate hosts for these pests. To address this issue, some farmers choose to burn these materials and spread the resulting ash onto their fields. This can be an effective way to destroy harmful germs and reduce the risk of pest infestation in crop fields.
Alternatives to Stubble Burning
Villagers commonly use it as a cooking fuel and to fill blank dug spaces. If left unused, the stubble can lead to rotten soil, so using it to fill spaces is a practical solution. Additionally, it can be used for betel leaf cultivation and in cottage industries, and can even be sold. Farmers also use stubble for floating crop beds: they pile the straw together and add vegetable seeds during the rainy season, resulting in good vegetable yields. Furthermore, stubble can be used to make sheds or cool houses, and mixed with soil for building houses. It is also a valuable source of food for cows.
Agricultural experts and farmers agree that by allowing these materials to decompose, they can transform into compost that can be used to enhance crop growth. One farmer described a process of digging soil, placing straw and other organic materials into it, and allowing it to decompose. They reported seeing positive results in their potato crops and noted that this method can also be effective for vegetable crops.
Knowledge and Attitudes Towards Air and Environmental Pollution
A significant number of farmers believe that the smoke generated from burning straw does not have any adverse effects on the air and environment. However, a significant number of residents have the opposite belief and think that smoke does have negative effects on the air and environment. According to agricultural experts, the primary focus should be on food and agriculture, and they do not seem to be as concerned about the potential pollution of the air and environment.
Health Impacts of Stubble Burning
Stubble burning usually starts in the afternoon and lasts until midnight, generating dense smoke that can be seen in the neighboring areas. The thick smoke produced by burning stubble makes it difficult to remain indoors, even with closed doors and windows. It can penetrate through closed doors and windows, leading to respiratory problems and unpleasant odors. Children are especially susceptible to the smoke’s effects, which may cause eye irritation and other health issues.
Policies and Regulations
As of now, there are no government restrictions in place regarding the burning of straws. Agricultural experts within the government believe that it can be beneficial for the soil and crops, which is why there is no policy to regulate this practice.
Limitations and Challenges
Farmers face challenges with storage space for stubble and often resort to burning it for cooking fuel. However, the cost of transporting the stubble can be prohibitive. Additionally, many farmers lack knowledge about effective straw management practices.
Discussion
The findings of the research highlight the various causes and alternatives to the practice of stubble burning in Munshiganj. The research indicates that many farmers resort to burning excess materials due to the lack of storage space, which can have adverse effects on the air and environment. However, farmers also believe that burning the stubble can have positive effects on soil treatment, and can lead to better crop yields.
