A.R. Siders is an Environmental Fellow at the Harvard University Center for the Environment where she studies climate change adaptation governance. Her current work explores decision-making and outcomes of managed retreat - the relocation of people and infrastructure out of vulnerable areas - as an adaptation and risk reduction strategy. She previously authored the Managed Retreat Handbook, a collection of case studies and legal strategies for state and local governments, while serving as Associate Director of the Center for Climate Change Law at Columbia Law School. Her most recent work on social justice implications in U.S. floodplain buyout policy is forthcoming in Climatic Change.

Siders received her PhD in Environment and Resources from the Emmett Interdisciplinary Program in Environment and Resources. Her doctoral work explored the concept of adaptive capacity: the traits and conditions that enable people and groups to adapt to changing conditions. Her work applying computational text analyis tools to conduct a meta-analysis of qualitative environmental studies literature won an early career award from the international Association of Digital Humanities Organizations. Her applied work on risk reduction, adaptive governance, and climate adaptation included collaborations with nonprofits and government agencies in Alaska, California, the Philippines, and United Kingdom. She continues to consult with non-profit organizations on the integration of climate adaptation in disaster risk reduction programs.

Prior to pursuing a PhD, Siders received a JD from Harvard Law School and served as a Presidential Management Fellow with the U.S. Navy. She has worked on a variety of capacity building, environmental sustainability, and human rights projects including naval capacity building in West Africa, counter-piracy measures in the Red Sea, health effects of mining runoff on indigenous populations, the effects of sea level rise on military installations, and national reporting requirements for unexploded ordnance clearance.
