Creating Wildfire-Resilient Communities In Utah: Fuel Treatments In The Wildland-Urban Interface, Luke Dutson, Kendall Becker, Katlyn Stemmler, J. Bradley Washa, Larissa L. Yocom Kent, Aish Chandrasekaran, Joseph D. Birch, Scott Hotaling

All Current Publications

In the western United States, decades of wildfire suppression and grazing have led to changes in the amount and type of wildland fuels. In many lower montane forests, fuels such as logs, dead trees, and fallen leaves have accumulated. In many sagebrush-dominated rangelands, annual grasses have invaded, and pinyon pine and juniper woodlands have encroached. These areas now threaten to burn at uncharacteristically high fire severity, a metric based on how much vegetation is killed. Climate change and rapid population growth have exacerbated this issue in Utah, increasing the threat wildfire poses to the state’s communities, infrastructure, and ecosystems. Fuel …

From Dialogue To Delivery: Engaging Non-State Actors In Gst Follow-Up, Aya Mohamed Sep 2025

From Dialogue To Delivery: Engaging Non-State Actors In Gst Follow-Up, Aya Mohamed

COP30

Climate action is falling short where it matters most, on the ground, because those doing the work are often excluded from the system's tracking progress. The Global Stocktake (GST), meant to assess global climate efforts, remains focused on national governments, leaving out non-state actors (NSAs) who lead much of the real-world delivery. This exclusion stems from structural gaps in Nationally Determined Contributions (NDCs) and the lack of formal ways for NSAs to engage meaningfully. Existing tools, like voluntary platforms and consultations, are not enough, they lack enforcement and true integration. This paper proposes two practical solutions: AI-powered Nested Climate Accounting, …
