Item Open Access Annual Trends in Plastics Policy: A Brief(2022-02-23) Karasik, Rachel; Bering, Janet; Griffin, Madison; Diana, Zoie; Laspada, Christian; Schachter, Jonathan; Wang, Yifan; Pickle, Amy; Virdin, JohnIn 2020, the Plastics Policy Inventory and accompanying report, 20 Years of Government Responses to the Global Plastic Pollution Problem, were published, providing a baseline for the trends in government responses to the plastic pollution problem, as well as highlighting some gaps. Since that time, momentum has grown toward negotiation of an international agreement as a collective response to the problem, even as governments and resources have been strained by the ongoing coronavirus pandemic. This first brief builds upon the 2020 report and baseline by adding new data on national policy responses to plastic pollution from 2020 and 2021. Assessment of the more up-to-date policy inventory suggests that the twenty-year trend of an increase in the number of national policies introduced to reduce plastic pollution has stalled. While additional data on national policies may subsequently become available to revise these estimates, if confirmed they would suggest a pause in government responses to the problem, coinciding with the pandemic (though we cannot show causality). Our goal is for this brief to be the first in a regular series of annual updates on the trends in government responses to the global plastic pollution problem.Item Open Access Dancing in the Squares(2015) Wang, Yifan“Guangchangwu,” or what is literally translated as “square-dancing,” is a form of public dance that has been exceedingly popular, albeit controversial, in China over recent years. Most of the participants are elderly women in their late-50s or above, who roughly fall in the category called “dama” (“big-mother”). Usually, a dancing group assembles in the evening and dances on a daily basis to the music played through a portable loudspeaker. Yet, because many dancing sites are in or close to residential compounds, the music played, or, the alleged “noise pollution,” have caused numerous conflicts nationwide. During the summer 2014, I conducted a three-months fieldwork on the dance in China. In this thesis, I first demonstrated how a specific guangchangwu dancing group organized in relation to the space it occupied, then I traced the media discourse of guangchangwu and showed how it became linked with elderly women, dama. I argue that this seemingly new and overwhelmingly women-dominated public dance emerges from a series of long existing activities, the embedded gender politics of which articulates China’s recent and ongoing revision of policies and laws regarding birth control and the retirement age. Moreover, it is precisely against the backdrop of such social discourse that the practice and persistence of individual dancing groups becomes meaningful: through an effective organizational structure, these elderly women made their existence visible, audible, and their stories irreducible.
Item Open Access Impact of Ecosystem Services Loss to Macroeconomic Productivity(2022-04-22) Hermanson, Max; Chen, Mingyi; Vanasse, Sam; Wang, YifanEcosystem service losses pose an enormous threat not only to the environment, but also to businesses and society. The Duke student team helped its client, Ortec Finance, assess frameworks around ecosystem service losses and risks to different business sectors by conducting a literature review, describing analysis methodologies, and providing recommendations. The literature review showed that quantifying the economic impacts of ecosystem services is effectively done through either partial-equilibrium or computable general-equilibrium models (CGE’s). The foremost publication regarding CGE models was found to be a report by the World Bank, which provides insights into how countries and economic sectors will differ between 2021 and 2030 due to BES losses. Additional literature showed consensus on three sectors: agriculture, raw material mining, and manufacturing are at the highest risk from ecosystem service losses. A flowchart was created to easily summarize how different ecosystem services link to various economic sectors. Geopolitically, developed countries in North America and Europe have low direct GDP dependency on BES. Other developing countries like China, India, and Brazil all have moderate to high GDP dependency. In comparing quantification methodologies used to analyze the economic impacts of ecosystem services, we recommended that Ortec Finance focuses on the Swiss Re BES Index as well as the ENCORE tool. The results from these two main approaches conducted by this report should feed into the expansion of Ortec Finance’s proprietary tool, Climate Maps, on ecosystem services.
