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). 

The most common air pollutants are called criteria pollutants and are regulated by the Clean Air Act and the EPA. These pollutants are: particles, ozone, nitrogen oxides, sulfer dioxide, carbon monoxide, and lead. The EPA have sections under the CAA that help regulate factories and air pollution in the environment. For example section 108 requires the EPA to identify the pollutants that are criteria pollutants, listed above, and determine if where they are coming from and if they "endander public health or welfare". Under section 109 the EPA had to set standards across the board for air pulltion in regard to human health and to the environemtn sperately (Christopher D. Ahlers 2016, 51-52).  There are many more sections that go into detail about what the CAA can do and what the EPA members are required to do as well. 

Following the article, the author J. Kenens has published another paper "Changing perspectives: tracing the evolution of citizen radiation measuring organizations after Fukushima (2020)" DOI: 10.1051/radiopro/2020041 (link) that draws on the research on citizen science in Japan with a new focus on the comparison of their practices directly after the nuclear accident and today. 

It is interesting to see how citizen science in Japan is enacted and how the concept of citizen science is dependent to the social and cultural context. Also looking at it not only from a top-down perspective, where universities or organizations are involved, but also the bottom-up perspective that includes only those practices that are done by citizens alone opens up a new space. As I am currently engaging with research on air pollution in different sites, I could build from this text in considering the link between "citizen-driven approaches and institutional imparatives in the governance" (p. 7) of issues with air pollution. 

The text is an article about citizen science in the aftermath of the Fukushima disaster in 2011. The first noteworthy detail about this text that struck me is the inclusion of Japanese words and even their original spelling. This creates a kind of closeness to the field that the authors did their research in. 

The authors engaged in multi-sited ethnographic fieldwork that took place in and around Fukushima but also in other geografical sites like Tochigi, Miyagi, Aichi, Tokyo and Kyoto. There, they conduct semi-structured interviews with various organisations that are all somehow involved with citizen science or radiation measurement.  To learn about the citizens that measure radioactivity and create their own data on radiation because of a lack of provided data by the government, a literature review of policy documents and workshops with those citizen scientists is performed. 

As the title of the work hints to, the text builds on discussions surrounding energy policy and energy investments. Throughout the work, Boyer (2019) discusses dimensions of energy transitions that range from job creation, forms of development (industry and otherwise). Most significant to take into consideration is the fact Boyer (2019) acknowledges energy development often occurs without at par social, political, and economic transitions. Boyer (2019) advances discussions of energy politics and transitions by highlighting the inherent problems energy transitions bring into communities where wind farm and green projects are envisioned. Here, we should note the impacts energy transitions may have on the most vulnerable populations, which have been and continue to be documented. In fact, it is documented that LMI communities tend to be least likely to sport energy-efficient, carbon neutral energy systems and appliances (Cluett et al., 2016; Elnakat, 2016; Kaza et al., 2014).

This text is particularly exemplary in documenting local community antagonism to energy transitions as it recognizes small-scale intrusions green energy may introduce. This varies from loss of agricultural planes to loss of fishing potential, as noises created by aeolian energy production can disrupt wildlife and their habitats. It is important to consider details like these in what can be considered microcosms of life. However, the text does not widely address how to move past these intrustions. Questions that still linger are: How can the introduction of green (aeolian and other) energy avoid damaging such microcosms? How can energy prices be made accessible to everyone thanks to the introduction of green energy instead of being used as an excuse to increase energy prices? What understandings are green energy investors missing to carry forward beneficial green energy projects? And, a question that the author asks from the beginning: How can the introduction of green energy benefit those communities in which projects are carried out?
