FOR ECOGOVLAB/CCEJP CURRICULUM: Use this as a research resource during 11th and 12th Grade Lesson 2 on Hazards.

What do you hope to get out of the lab?

I hope to be involved in projects that aim to gather scientific evidence to inform environmental decision making and advocate for greater equity and justice in environmental governance. Through this work, I hope to learn the skills needed to engage in community based research and leverage community knowledge as expert knowledge. In my department, things are often siloed and issues are only seen through one perspective. I really want to gain more experience in collaborating with a wide array of stakeholders to come up with approaches to mitigate the environmental injustices experienced in under-resourced communities.

Harmful PM2.5 emissions in Dhaka, Bangledesh prompting researchers to study emissions during winter and monsoon season.

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).
