Assessing the PM2.5 impact of biomass combustion in megacity Dhaka, Bangladesh - PubMed (nih.gov)

This article is about crop burning in Dhaka, Bangladesh and attempts to figure out if there is more or less harmful PM2.5 particulate air pollution caused by either fossil fuels or biomass, and during which season is one or the other higher in the air pollution it produces. During monsoon season, fossil fuels lead in the most PM2.5 releases at 44.3%. When it is not monsoon season and is the winter season, the percentages are way higher for PM2.5 air particulate releases at 41.4% for the remainder of the year. Across the globe, there are now people stepping up to uncover the true and real environmental and health impacts this harmful particulate byproduct causes in different parts of the world and with differring weather conditions than what we see in North Carolina.

This study is set in South/Southeast Asia and uncovering that, when trying to count the percentages of PM2.5 put off during biomass, the true amount of emissions were being gravely undercalculated. Specifically rice straw burning becuase the amount burned varied so much because of different harvest and burning practices that it just wasn't taken into consideration. What this study does is go bottom up using these strategies: "subnational spatial database of rice-harvested area, region-specific fuel-loading factors, region, and burning-practice-specific emission and combustion factors, including literature-derived estimates of straw and stubble burned"(Lasko et al. 2021, 1). 

In this essay the authors have highlighted some of the stakeholders in the fight against industrial biomass operations as members of the surrounding community who live with these operations as close as their own backyards, and experience the environmental pollution directly everyday. They highlighted Belinda Joyner, a resident of Northhampton County, and an environmental activist who rose to defend her community and their lands and livelihoods due to expanding hazardous infrastructures such as the Atlantic Coast Pipeline and the Enviva power plant. Other stakeholders besides activists and organziers such as Belinda include the people of Northampton County who attend hearings with government officials and take a stance agaisnt pollution, as well as organizations such as the Dogwood Alliance. The county is predominantly Black and working class, one of several in North Carolina that bear the brunt of exploittion and pollution by powerful biomass manufacturers such as Drax and Enviva.

This timeline essay provides more examples from recent years of community responses and collective action for environmental justice.

The development of both pipelines and CAFOs (confined animal feeding operations) in eastern NC have prompted action from justice organizations such as the North Carolina Environmnetal Justice Network (NCEJN). To address the ongoing problem of CAFOs, NCEJN has provided a number of resources on their site, as well as ways to take action by signing a petition to stop the use of hog waste as fertilizer. Prior to the Atlantic Coast Pipeline (ACP) being canceled in 2020, NCEJN played a role in organizing protests and taking legal actions- in conjunction with many other community member and activist groups- against Dominion and Duke Energy, the companies responsible for the ACP's construction. 

The authors, Andrew Lakoff and Stephen Collier both study anthropology. They have written several papers together focusing on the social and cultural types of knowledge concerning health and medicine. Lakoff works at the University of Southern California and Collier is the Director of Anthropology for the New School.

The authors argue that while recent changes in health security have led to a modern knowledge base and understanding of health threats these new systems are still forming and adapting as the health problems faced change.

The main argument is supported primarily through policy changes that show a changing approach to public health safety in the government and private organizations, with specific examples such as changes to the US government funding for biodefense research in the early twenty-first century. The paper also includes examples of changing scientific knowledge during the later twentieth century, referencing studies and reports that highlight the changing opinions of the scientific community. Finally, the authors divide the paper into several sections each outlining a specific type of problem and the practices devised as a solution, this format clarifies the main argument and aids the reader in understanding the authors views.

“There is no such thing as being “too secure.” Living with risk, by contrast, acknowledges a more complex calculus. It requires new forms of political and ethical reasoning that take into account questions that are often only implicit in discussions of biosecurity interventions.” (Lakoff 28)

“On the one hand, they examine the different political and normative frameworks through which the problem of biosecurity is approached: national defense, public health, and humanitarianism, for example. On the other hand, they examine the styles of reasoning through which uncertain threats to health are transformed into risks that can be known and acted upon” (Lakoff 12)

“These initiatives build on a growing perception among diverse actors—life scientists and public health officials, policymakers and security analysts—that new biological threats challenge existing ways of understanding and managing collective health and security. From the vantage point of such actors, the global scale of these threats crosses and confounds the boundaries of existing regulatory jurisdictions. Moreover, their pathogenicity and mutability pushes the limits of current technical capacities to detect and treat disease” (Lakoff 8)

The primary method of supporting the main argument is a series of historical examples including policies such as those created by the World Health Organization, outbreaks including AIDS, and previous attempts to provide health security such as the Smallpox Caccination Program. The use of these examples highlights the changing nature of health problems and how that effects the type health security. Specific dates and data from the examples is included, which allows for a more detailed analysis to support the main argument.
