As the global climate crisis accelerates, cities around the world are grappling with an increasingly urgent question: how can local governments protect communities, infrastructure, and ecosystems from the rising tide of environmental disruption? This May, Stanford University will bring that question to the forefront with a landmark event examining how two dynamic and diverse cities — Los Angeles and Tel Aviv-Yafo — are responding to the climate challenge from the ground up.

Taking place May 29–30, 2025, and hosted by the Visiting Fellows in Israel Studies program at the Center on Democracy, Development and the Rule of Law (CDDRL) and the Environmental Social Sciences department at Stanford’s Doerr School of Sustainability, “Climate Resilience and Local Governmental Policy: Lessons from Los Angeles and Tel Aviv” will be the largest academic conference ever held on Israel’s climate policy. The two-day event will convene experts from both cities to explore how local institutions are building equitable, sustainable, and adaptive systems to confront growing environmental risks.
 

How does the history and culture of the American West affect its capacity to address Climate Change? In a CDDRL seminar talk, Bruce Cain addressed the question by drawing on findings from his latest book, Under Fire and Under Water: Wildfire, Flooding, and the Fight for Climate Resilience in the American West (University of Oklahoma Press, 2023). Cain — director of the Bill Lane Center for the American West, Professor of Political Science at Stanford University, and CDDRL faculty affiliate — argued that the federalist nature of the U.S., along with regional history and idiosyncratic human behavior, have made resolving collective action problems uniquely difficult.

Cain opened his talk with a reflection on American federalism. He indicated that the U.S. strongly federalist political system aims to delegate the provisions of specific public goods across its national, state, and local jurisdictions. However, the worsening issue of climate change — and its negative externalities — transcends these jurisdictional borders, thereby creating a coordination challenge. There is fracture at both the vertical level — between federal, state, and local governments — and the horizontal level, across branches of government and between states and localities themselves. Polarization, geographic sorting, and rising inequality have exacerbated the problem.

Adequately addressing climate change requires extensive coordination and planning, which is not often the strength of a highly diverse democracy. Furthermore, the public, even when it is not polarized along party lines, may hesitate to take sufficient steps to protect climate progress because people may not want to pay now for future benefits.

This national framework serves as the backdrop for the West’s regional history. The initial move to the West required incentives, as people were uneasy traveling into a land seen as untamed and wild. This created an appropriative culture, as settlers had to be motivated to undertake the risks of living and working in the American West. After World War II, the private nature of this land began to get in the way of the maturing environmental movement.

The Western climate is arid, a characteristic that will be further exemplified by the changing climate. As such, in California, we face two “water problems.” First a “too little” water problem — droughts. But we also face a “too much” water problem — sea level rise and flooding. The “too little” water problem leads to extensive wildfires — the smoke from which has serious health effects. While fires are one of the most visible and concerning effects of climate change, their bearing on electoral outcomes is marginal, as only a small number of people lose their homes in a given year.

In many places where homes have been destroyed, they tend to be promptly rebuilt. Unfortunately, this is not the only case of building in disaster-prone areas. Infrastructure continues to be built in flood zones on the coast, and neighborhoods routinely decimated by fires are erected time and time again. But this issue is confronted with a competing priority, namely the lack of housing in the state, making policy decisions all the more complicated.

Governmental fractioning and perverse incentives make the coordination necessary to address these issues even more difficult.

So what does all of this mean going forward? Cain believes the federalist nature of this country may mean a lower ceiling on progress but a higher floor in the long run. Our progress will be slower but more resilient to party shifts in the executive. He also predicts that U.S. decarbonization efforts will vary more by income and lag behind other OECD countries. Finally, in the absence of coordination, the U.S. strength will remain in providing innovation and pushing for the early adoption of first-mover policies.

How can we encourage citizens to comply with desired civic behaviors? In a CDDRL seminar series talk, Salma Mousa, assistant professor of Political Science at UCLA and former CDDRL postdoctoral fellow, explored this broader question via a field experiment in Lebanon. In conjunction with a municipality and local NGO, Mousa and her team evaluated the effectiveness of a waste sorting intervention.

In 2015, some of Lebanon’s primary landfills reached capacity, forcing displaced waste into the streets and prompting public outcry. Lebanon's crisis is not for lack of money; the country spends ten times more than nearby Tunisia despite having only half the population of Tunisia. This suggests that Lebanon’s issue reflects mismanagement rather than a lack of resources.

A key component of this mismanagement is a lack of sorting at the source of waste. Effective sorting, Mousa argues, requires collaboration between citizens, civil society, and government. Overcoming this collective action problem does not just require physical infrastructure and intrinsic motivation; it also requires that people trust that their neighbors and government will do their part.

To test their sorting intervention, Mousa and her collaborators chose the small, wealthy, and predominantly Christian town of Bikfaya. The town is characterized by high levels of social cohesion and a “green” reputation that is central to its identity.

Working with the municipality and an NGO called “Nadeera,” the team divided the town into neighborhoods, randomly assigning treatment and control. The treatment group received a box with QR codes they could put on their trash bags and an app where they could access feedback on their sorting. They were given instructions on proper waste management and told to sort their waste into recycling, organic materials and other — sticking their personal QR codes on each bag.

After pickup, inspectors at the nearby waste management facility would use the app to provide personalized feedback on sorting quality, giving participants the opportunity to improve.

This intervention makes trash sorting a sanctionable behavior, with social pressure to enforce it, because participation is visible to neighbors via the QR code stickers placed on their trash bags.

The team examined three distinct outcomes. First, the quality of sorting. Second, participation in a raffle for “green” prizes, designed to measure the impact of the intervention on other climate-friendly behaviors. Finally, they measured participation in volunteer opportunities for environmental initiatives.

Two months after the intervention, the program improved sorting quality by an average of 14 percent. That said, at the twelve-month mark, the effect was null. Eight months in, the program and app feedback ceased, making it difficult to distinguish between diminishing long-term effects and lack of sanctioning.

Treated participants entered the raffle at two times the rate of the control group, but the mechanisms behind this increase remain unclear. The rise in uptake could be attributed to behavioral change or familiarity with the NGO as a result of treatment.

On the volunteering measure, the treated group saw a 7% negative effect, meaning they were less likely to sign up for local environmental initiatives if assigned to treatment. Mousa and her collaborators theorize that this is due to moral licensing, or the feeling that they have already done their part.

While the effects of the primary outcome became null after a year, the treated group did see a substantial improvement in sorting quality — a big win for the town on environmental and economic measures. Future iterations of this intervention will include consistent monitoring or cash benefits to promote prolonged participation.

How does climate change shape citizens’ views of political leaders and institutions? At a CDDRL seminar series talk, Amanda Kennard, assistant professor of political science at Stanford University, and Brandon de la Cuesta, a postdoctoral fellow at CDDRL and the Center on Food Security and the Environment (FSE), explored the effects of climate shocks on political trust, employing innovative machine learning methods.

To illustrate the link between the environment and human social systems, Kennard began with an anecdote about street vendors in Liberia. She noted that research has found that the single largest factor influencing vendors’ decision to join the formal economy is precipitation. From crop cultivation to the uptake of government programs, climate sets the stage for all other systems.

The existing literature on the political effects of climate links extreme temperatures to civil conflict and flood events to anti-incumbent voting. However, it has yet to fully explore the effect of climate on state actors or state structures.

Kennard’s and de la Cuesta’s paper focuses on Sub-Saharan Africa, characterized by a diverse set of political, economic, and demographic circumstances.

The authors studied public confidence in heads of state, local leaders, opposition parties, the police, the courts, and the bureaucracy. In the face of the changing climate, the authors are seeking to understand how people perceive state performance, corruption, and democracy.

At the start of this research project, the presenters explained, the available data lacked the spatial and temporal resolution necessary for credible subnational analysis. Accordingly, Kennard, de la Cuesta, and their team worked to create a machine learning algorithm that could harmonize survey questions across survey rounds and countries. These geolocated surveys were then paired with remote sensing data to create a complete picture of the association between climate change and public opinion in a given place and time.

Kennard and de la Cuesta used the data to study the effects of environmental shocks on relevant economic, social, and political outcomes. In terms of economic and social well-being, the team found that temperature shocks led to meaningful increases in dependence on informal networks for borrowing and remittances and to a decrease in interpersonal trust.

On the political side, they found that climate change is associated with statistically significant (albeit small) negative effects on public confidence in local bodies, the president, and the ruling party, along with some state institutions like the police and court system. While the effects of climate change on satisfaction with democracy were directionally consistent, they were, for the most part, not statistically significant.

Several countries in Africa have already seen devastating temperature changes of two degrees Celsius, with another two likely to come before 2050. This change is pushing many people out of the so-called human habitable zone, so the current effects on measures of economic, social, and political distress are only likely to increase going forward.

Kennard and de la Cuesta indicated that they hope to make the machine learning infrastructure they have developed scalable and open source, thereby allowing researchers to access specific geolocated survey responses. 

Kumi Naidoo, a prominent South African human rights and environmental justice activist, spoke about transformative change, the climate crisis, and how to move human hearts and minds during a presentation hosted by the Center on Development, Democracy and the Rule of Law (CDDRL) on January 31.

His talk, “Creative Maladjustment and the Climate Crisis,” was the 2024 installment of the annual Payne Distinguished Lecturer Series at the Freeman Spogli Insitute for International Studies (FSI). Naidoo, who also served as the executive director of Greenpeace and secretary general of Amnesty International, is this year’s Payne Distinguished Lecturer at CDDRL.

“The moment of history that we find ourselves in is one in which pessimism is a luxury we simply cannot afford,” said Naidoo, who, at the age of 15, started campaigns to dismantle South Africa’s apartheid system. He added that tackling the environmental crisis is a big puzzle, and it seems as if humanity is still trying to figure out the right thought processes. Yet, to truly grasp how to co-exist with nature and start thinking long-term instead of just short-term, authentic change will require a fundamental shift in mindsets, one inspired by positivity and creativity.
