Identifying Accessibility Improvement Opportunities For Global Environmental Communication Websites, Alicia Mason, Josh Compton, Sakshi Bhati

Faculty Submissions

Digital environmental information presented with low web accessibility reduces parti-cipation in environmental advocacy and information seeking behaviors for many people with disabilities, creating a consequential digital divide. We use WEB AIM computer automated analysis of web accessibility to assess the general accessibility of online environmental communication messages. Results show 95.3% of the popular websites in our sample had indicators of potentially critical accessibility errors. Our findings highlight the importance of addressing digital environmental information accessibility shortcomings so that educational, informational and persuasive environ-mental messages can increase environmental literacy of vulnerable populations and help to bridge the digital divide.

Deforestation, Trade Liberalization, And Environmental Politics In The Brazilian Amazon: 1990-2022, Kerin Debany

Araneum: Richmond Journal of American & Global Affairs

This paper explores the relationship between trade liberalization and deforestation in the Brazilian Amazon from the beginnings of widespread trade liberalization in the 1990s to 2022. This paper, through an analysis of deforestation from soy and beef production, concludes that trade openness and foreign direct investment (FDI) alone cannot fully explain the rapid environmental degradation occurring in the Brazilian Amazon. Despite Brazil’s efforts to integrate into global markets, the levels of trade and FDI are relatively low. Instead, the policies of Brazil’s government play a decisive role in shaping deforestation trends. The contrasting presidencies of Luiz Inácio Lula da Silva …

Rethinking Environmental Disclosure, Annie Brett

UF Law Faculty Publications

Twenty years ago, legal scholars and regulators alike were convinced that information-forcing regulations heralded a new era in environmental law. Coming off the success of the Toxics Release Inventory (TRI), which seemed to decrease toxic chemical pollution solely by forcing industry to disclose if they released certain chemicals, many called information regulation the third wave of environmental law. New information disclosure policies were enacted and old policies reinvigorated, leading to a plethora of information-based regulations throughout environmental law. Now, twenty years later, the emergence of big data and artificial intelligence (AI) approaches to environmental analysis have only further increased the …

Regulator Preferences And Underinvestment In Drinking Water Infrastructure, Chunyu Guo

Electronic Theses & Dissertations (2024 - present)

The infrastructure of U.S. drinking water systems faces chronic issues of low quality and underinvestment. As the water utilities in the U.S. are typically managed and regulated at the local municipal level, investment levels depend on the municipal regulator's preferences. Drawing from a dynamic framework, I specify and estimate the local regulators' objective function over drinking water infrastructure investment. This framework highlights the tradeoff between profit and consumer surplus and reveals how regulator preferences can deviate from net surplus optimization, resulting in underinvestment. My findings provide significant evidence that the drinking water infrastructure is underinvested. I reveal that the regulator's …
