This project studies how climate policy networks around the United States are evolving. It documents the ideological and policy networks operating at the state and federal levels on climate/clean energy issues and observes how they are changing over time. The research maps out what clusters are forming around particular climate-related issues, what explains the formation of these clusters, and how they are related to specific policy actors. The methodology, which builds on previously NSF-funded research (see COMPON below for details), involves data collected from public documents, social media, and from policy actors engaged in the debates around climate/clean energy issues.

Along with the federal level, the project is currently focusing on state-level activities in Florida, Nevada, North Carolina, and Ohio.  This project is funded by the MacArthur Foundation.

Code for running the analysis in R



This project analyzes the people who participate in large-scale protest events around the world: who are they, what motivates them to protest, and how are they connected to one another. Current research on this project is focusing on analyzing data collected from the Women's March on Washington (21 January 2017), the March for Science (22 April 2017), and the People's Climate March (29 April 2017). In addition to looking at who is participating in the specific protest events, these data will also be compared to those collected at other large-scale mobilizations since 2000. Data have been collected at the 2014 People's Climate March, the 2009 Copenhagen Climate March, the 2004 RNC Protests, as well as a numerous other protest events.

Through this analysis, we will be able to answer broad questions about large scale political mobilizations, as well as those about political engagement, organizational embeddedness, network connections among protest participants, and how protest around contentious issues connect social movements and change over time.

This project, which is a collaboration with colleagues at the US Forest Service, studies how civic groups are working together to steward their local communities in cities in the United States. Funded by the US Forest Service (USFS) and a grant from the National Science Foundation, we studied these groups in New York City starting in 2007. More recently, we conducted a similar census of groups in Philadelphia. These data arel being analyzed and compared with other cities.

The USFS manages a website for cities doing STEW-MAP analyses.
