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. 

Emissions from Biomass Burning in South/Southeast Asia; correcting the miscalculation about the PM2.5 emissions from burning.

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 Clean Air Act and the EPA laws and regulations against harmful PM2.5 air pollutant matter

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.

COVID-19 collaboration call: project reflections & directions (Response)

I am particularly interested in comparative approaches on how different sites (and academics in those places or studying them) are thinking about COVID in their localities. How are people dealing with issues of trust and information in an era when entire archives are in danger (like the police archives in Guatemala which had been rescued in the past decade and are now in danger). This question expands beyond COVID but has become crucial in the context of Ecuador where reliable data is hard to come by. Another important aspect for us is how indigenous communities are fairing amid the pandemic (here a fabulous article on the terrible situation in Brazil—which is not so different to Ecuador's). This touches on issues of communication, infrastructure, language, systemic racism, and more. Finally, I am also interested in ways in which we might be a able to contribute to some of these issues from our academic spaces. Collaborators (which can take many forms) are certainly welcomed.

Mobilizing comedians/political commentators

makasuarez
One of the mediums of communications that has reached well beyond the US are monologues by well-known comedians that are partly explaining, partly commenting on current BLM events. One of them is Hasan Minjah and his message We Cannot Stay Silent About George Floyd where he calls on migrants in particular to act in the face of racism rather than perpetuate it. Nearly 4 million people have seen the clip, which is part of Minjah's broader Netflix TV series The Patriot Act (who makes these videos and pays for them is also relevant here). In Ecuador, this video circulated mainly among English speaking young adults, mainly via WhatsApp. It triggered many group discussions around what is happening in the US and how we might think about this political moment with regards to our own racist history. The second video is by Trevor Noah and has over 8 million views. In it, he explains what racism means in relationship to the social contract and how it has failed for too many people. To me it is particularly interesting to see the pedagogical approach their videos take and the truly diverse audiences they speak to. The ripple effect the videos have is important for thinking about how the BLM movement has mobilized political sentiments well beyond the US and what mediums can effectively do this (and for whom).

I'm a co-founder of Kaleidos - Center for Interdisciplinary Ethnography, a space for academic experimentations supported by two top ranked universities in Ecuador (University of Cuenca and FLACSO-Ecuador). We are located in Cuenca, where I am assistant professor of medical anthropology. Together with a team of researchers we have been tracking covid19 with a specific focus on Latin America through Spanish language podcasts, collective texts, webinars, and online forums.

My current ethnographic interest is on documenting data distrust networks from the neighborhood scale to the national level in Ecuador, and how these networks have produced distinctive approaches (and failures) to the current pandemic.

Maka Suarez: thinking about air pollution locally

makasuarez

I was interested in learning about how air pollution has been talked/researched in the New Orleans area. Mainly, the need to highlight local specificities and historical analysis. A 1950s study on air pollution in New Orleans (Air Pollution and New Orleans Asthma), for instance, documented asthma incidence among black communities (sadly the article still uses the N word), and its relationship to underground fire burning in nearby dumps. The study is more comprehensive and did a census in part of the city as well as a number of medical tests on 84 individuals.

A second study, this one from 2007, documented asthma in children (Prevalence of Indoor Allergen Exposures among New Orleans Children with Asthma). It has a relevant focus of the differences between document indoor allergen exposure in different areas of the US and how subtropical weather in NOLA plays an important role in the kinds of allergies that children with asthma face. One of the main findings of the study can be summarized in the following quote “our data show that asthmatic children in New Orleans may be exposed to a greater number of allergens at moderate to high levels compared to asthmatic children living in other inner cities and to the general population.”

Finally, a third reference, the book Race, Place, and Environmental Justice After Hurricane Katrina: Struggles to Reclaim, Rebuild, and Revitalize New Orleans and the Gulf Coast talks about something, others have already pointed out (@Omar Perez Figueroa for instance) regarding areas that undergo dramatic change and hardship after natural disasters like hurricane Katrina and Rita. This book, particularly chapter 5 (though I can’t access the full text) explains the highly toxic environment that resulted (and remains) in the New Orleans area due to little clean-up action following the disasters. Lack of funding, deference to poorly resourced local authorities, and policy-failure all affect New Orleans (and many of our sites of research) particularly the fate of vulnerable communities.
