Revealing + Redressing Injustices in Climate Adaptation
My research demonstrates that major climate adaptation projects around the world are producing inequitable and unjust land use plans and projects within cities. These projects have to be seen not only in terms of what they do for or to low-income communities, but vis-a-vis what is done for or not done to wealthier residents. In addition, cities have long relied on resources from outside their own borders. Under climate change, their efforts to securitize their own safety by extracting more water or diverting floodwaters from/to rural areas can negatively impact surrounding regions. This critical research reveals how mainstreaming adaptation into current governance institutions and planning processes can sustain existing racist, classist, and unsustainable policies. It also reveals how adaptation planning implicates regional geographies – watersheds, metropolises – as well as higher levels of government whose policies drive and constrain local responses.
To counter tendencies towards inequitable adaptation, I research institutions related to core aspects of land governance: regional governance, fiscal policy, land use regulation, and property rights regimes.
Regional Governance of Climate Adaptation
One remedy to local, exclusionary adaptation is to upscale governance to the metropolitan region. This was the focus of my dissertation on climate collaboratives in five U.S. metropolitan regions. These have enabled more localities to begin adaptation planning by expanding access to data, technical assistance, and networks. However, initiatives advocate for more local resources and authority rather than regional capacity and governance. This potentially accelerates uneven intra-regional adaptation as the most impacted municipalities confront adaptation limits. Fundamentally, my research reveals the limits of soft regionalism in changing development choices on the ground.

Fiscal Policy & Challenges under Climate Change
Recent disasters and growing concerns about climate change have spurred calls for cities to retreat and avoid developing in coastal areas. Cities can ill afford to take these steps because the decentralization of municipal services, fiscalization of land use, and fragmentation of jurisdictions into 100+ governments per metro area make local governments jealously guard their property tax rolls. In some coastal bedroom suburbs, property taxes comprise 70% of local government revenues. However, sea-level rise, floods, fires, and other climate impacts will increase the cost of local services and reduce local revenues – sometimes upwards of 50%. This limits their ability to fund services and infrastructure, leaving them more exposed to future disasters, downgraded municipal bond ratings, and increasing the cost of future adaptation. This research highlights the need to stop fiscalizing land use and start regionalizing wealth sharing and housing production to avoid the creation of climate slums and resilient enclaves.

Property Rights + the Power of Collective Land Tenure
Many adaptation projects focus on the scale of individual property – for flood insurance, elevating homes, providing disclosures during property sales, and floodplain buyouts. With 13 million people currently living within 6 feet of sea levels, we need to enable action in ways that doesn’t require every individual to navigate the complexity from scratch. Meanwhile, individual residents living in more climate-safe areas also have little power to confront and resist climate gentrification. My research, along with colleagues, explores the potential for collective land ownership – for instance through community land trusts, cooperatives, indigenous communal land management, land readjustment, or even homeowner associations – to help communities resist climate gentrification, mobilize collective action, and support more equitable adaptation at a neighborhood scale.
Resident-Owned Resilience: Cooperative Land Ownership Enable Transformative Climate Adaptation for Manufactured Housing Communities? (with Zachary Lamb, Berkeley)
Mobile homes comprise most of all affordable housing in the United States that is not subsidized, buts residents are vulnerable to both environmental risks and displacement by eviction. Ongoing research explores how collective land tenure affects their ability of U.S. mobile home parks to respond to economic, health, and environmental needs.

(Shi, Lamb, Qiu, Cai, Vale, Habitat International, 2018)
We show how collective tenure enabled Shenzhen’s rural poor to capitalize on the city’s urbanization and improve their built environment, social and environmental services, resist and negotiate the terms of displacement. However, these rights did not extend to migrant tenants. Property rights accrue to the holder of those rights, and the wider the net, the wider the redistributive benefits.
