Climate-Induced Displacement is a Global Phenomenon, but Not Evenly Experienced

As world leaders presented their plans to combat rising global temperatures at the annual United Nations Climate Change Conference (COP 28) in Dubai from Nov. 30-Dec. 13, 2023, discussions are centered on how countries can cut greenhouse gas emissions and mitigate a dire environmental future. But a UC Berkeley researcher says that future is already here for millions of people displaced by the climate crisis. And those climate refugees are predominantly from formerly colonized countries that are not responsible, in large part, for the factors that exacerbate climate change.

But a UC Berkeley researcher says that future is already here for millions of people displaced by the climate crisis. And those climate refugees are predominantly from formerly colonized countries that are not responsible, in large part, for the factors that exacerbate climate change.

Those nations — in the global south regions of Africa, Latin America, the Caribbean and much of Asia and Oceania — also lack the wealth and infrastructure to withstand intensifying natural disasters, rising sea levels and the collapse of industries dependent on stable climates, according to a recent Berkeley report.

“There are many examples of how global south countries face the brunt of a crisis they did not produce, due to the activities of countries and industries in the global north,” says report co-author Hossein Ayazi, a senior policy analyst at UC Berkeley’s Othering and Belonging Institute. “So, we want to help protect the most marginalized — climate-induced displaced persons — while targeting the sources of their marginalization.”

That is why the institute’s Global Justice Program recently launched an interactive database that helps both policymakers and impacted communities explore global data on climate-induced displacement. The report also offers strategies to ensure the protection of people displaced by the climate crisis, and climate resilience for them moving forward.

Ayazi said the research shows that sea levels are expected to rise drastically in the coming decades, which will impact nearly 40% of the world’s population that lives in coastal areas. And over 75% of all coastal populations — 90% of the world’s poor rural coastal areas — live in the global south.

Berkeley News spoke with Ayazi about what’s causing climate change displacement and what needs to happen to protect climate refugees and make their communities more resilient.

Berkeley News: Your research unpacks why people in the global south are more vulnerable to being displaced from the impacts of the climate crisis. What are some of the economic dimensions of this vulnerability?

Hossein Ayazi: Many countries in the global south have a relatively large percentage of their gross domestic product (GDP) derived from agriculture, forestry, and fishing — industries that are by nature more vulnerable to a changing climate.

In Ethiopia, for example, agriculture comprises almost 40% of its total GDP. That sector also employs over 80% of its population. So as these countries experience climate extremes — droughts, floods, increased temperatures and so on— their economies are impacted on a deep level.

A defining feature of countries in the global south is that their economies have been organized by, and to the benefit of, the global north — wealthier and powerful nations in North America and Europe. This means agricultural production that’s largely export-oriented, and not diversified, makes these countries especially inflexible and vulnerable to climate impacts.

Berkeley News: What other significant economic or financial factors cause or worsen climate-induced displacement?

Hossein Ayazi: Global south countries have a high external debt burden, with surcharges making things worse. In fact, global south debt payments in 2023 reached their highest level in 25 years.

This high debt burden means a poor sovereign credit rating, and a lack of fiscal space to invest in climate-resilient infrastructure and economies that can adequately respond to disasters. This is true at the individual and household level: When disaster strikes, it’s hard for people to manage when they are struggling financially.

Protecting climate refugees and affording people the right to stay in their communities means addressing such issues.

Berkeley News: While the focus of your data is on the global south, when you talk about climate displacement in this way it seems like it can happen anywhere — even in the United States.

Hossein Ayazi: It certainly can. Consider Hurricane Katrina in 2005. Residential segregation and decades of disinvestment in New Orleans’ levee infrastructure meant that when the storm hit, it would be the city’s poorer Black residents who would be displaced or lose their lives.

In the wildfires in Maui this year, we saw the inequalities in those communities exacerbated. Tourists had the means to reach safety and secure a place to stay, while many Native Hawaiians struggled to flee, save their homes, or recover afterward.

The climate crisis is a global phenomenon, but its impacts are not evenly experienced.

Berkeley News: Your research reveals that industries using extreme amounts of nonrenewable energy sources mostly come from wealthier countries in the global north. How do those industries affect the surrounding communities they inhabit?

Hossein Ayazi: Globally, we have come to be dependent on extractive, exploitative industries that might provide for some, but collectively harm us all, and certainly harm the people in closest proximity to them.

These industries are usually placed in marginalized communities in the global north — and in countries across the global south — and, rife with health and environmental impacts, they become mainstays of the broader economy.

Berkeley News: What is an example of this locally?

Hossein Ayazi: We can look to Richmond, California, and the Chevron oil refinery located there. Nearly 24% of the city’s general fund comes from the refinery, which also provides regional employment.

So, the question is: How do communities and countries become less dependent on these extractive industries that harm them, and us? How are these harms — past and present — addressed?

That’s the point of this work: Protecting peoples most harmed by the climate crisis, targeting the sources of the climate crisis, and building communities and economies that are just, sustainable and resilient against the climate crisis.

Berkeley News: What do world leaders need to do to make this vision a reality?

Hossein Ayazi: World leaders need to recognize the rights of people displaced by the climate crisis and across international borders. They also need to act upon demands for the transformational changes needed to materialize inclusive, just, and climate-resilient communities.

These demands entail ending the exploitation of land, resources and labor, and demilitarizing borders, among other key climate justice demands.

Berkeley News: What type of policy does your research recommend?

Hossein Ayazi: What we conceptualize as the “Right to Stay” is not only the right for climate-displaced people to safely resettle when their lives are uprooted. It is also the right to stay in place amidst the climate crisis, and against the extractive and exploitative structures that are forcing them to move.

To be able to aid the transition to climate-resilient societies and regenerative economies globally — while protecting the world’s most marginalized and exploited people and communities — a Right to Stay policy platform entails:

Legal rights for all peoples displaced by the climate crisis, within and across national borders
Climate reparations to countries in the global south, whose vulnerability to the climate crisis follows centuries of global north extractive and exploitative political and economic activity
Just transitions that democratize, decentralize, and diversify economic activity and (re)distribute resources and power

Berkeley News: Why should the general public care about people displaced by climate change?

Hossein Ayazi: To address the condition of climate displacement is to come at the work of climate justice from multiple angles — from worker protections to migrant rights to prison abolition to reparations for the harms of colonialism and slavery to food sovereignty, and so on.

These struggles for justice and self-determination are all connected, especially under the climate crisis.

It’s that work that we’re trying to hold together through this database, and through the reports and recommendations that accompany it. Our work aims to map and strengthen this global constellation of efforts by helping the public and policymakers understand the structural nature of climate displacement.

Berkeley News: How do we build climate resilience in our own communities?

Hossein Ayazi: It begins with organizing ourselves as renters, as students, as workers, as debtors and so on. It’s about all the ways that we can collectively determine and respond to the sources of hardship in our life, in ways that are connected to these other issues.

And it must be through a hopeful message, a message that we’re going to co-create the future that we all deserve to live in.

Closing the Gap: What the Data and Frontline Experiences Reveal About Cancer in Black California

OAKLAND POST — According to a UC Davis study, “The Burden of Cancer Among Black/African Americans in California,” Black cancer patients were more likely than White patients to be diagnosed at a later stage and to have multiple health conditions, making treatment more difficult. They were also far more likely to live in low-income communities and rely on public insurance—evidence that economic inequality and barriers to care are helping drive disparities in the state’s cancer crisis.

Kris Benz, a disabled Black veteran, is no stranger to cancer. In 2012, he was diagnosed with salivary duct carcinoma, a cancer so rare it strikes only about 1 in a million people each year.” But he beat it after six weeks of radiation and removal of his right salivary gland.

“I was cancer-free after six months,” he said.

Now, a new concerning mass has appeared in his neck despite months of scans. His doctor suspects it is cancerous, but Benz, who lives near Palm Springs, will not know for certain until a biopsy.

Compounding that uncertainty is a gap in his coverage. Benz is two work credits short of qualifying for Medicare, but returning to work could jeopardize his Department of Veterans Affairs (VA) disability status and funding. Buying Medicare Part A would cost $568 a month, leaving him “winging it.”

Benz is also frustrated that the VA will not schedule his scan and biopsy before his consultation, which will require another round of appointments afterward.

“It’s about money,” he said. “Doctor’s appointments, they get the money. There’s no preventive medicine here anymore.”

Although he calls the VA “a great organization,” he believes it is hampered by bureaucracy. For now, he remains “in limbo” waiting to complete his appointments.

His experience reflects one of the most persistent health equity challenges facing Black communities: access to care.

According to a UC Davis study, “The Burden of Cancer Among Black/African Americans in California,” Black cancer patients were more likely than White patients to be diagnosed at a later stage and to have multiple health conditions, making treatment more difficult. They were also far more likely to live in low-income communities and rely on public insurance—evidence that economic inequality and barriers to care are helping drive disparities in the state’s cancer crisis.

That same study reports that between 2014 and 2018, the ten cancers most frequently diagnosed among Black/African American women in California were, from one to ten, breast, lung, colorectal, uterine, pancreatic, kidney, non-Hodgkin lymphoma, thyroid, myeloma, and ovarian cancers. During the same period, the ten most commonly occurring cancers among Black/African American men in California were, from one to ten, prostate, lung, colorectal, kidney, bladder, liver, non-Hodgkin lymphoma, pancreatic, myeloma, and oropharyngeal cancers.

Researchers attribute the gaps not to biology but to social and economic inequality connected to structural racism. An American Cancer Society analysis found educational attainment was a stronger predictor of the mortality gap than race alone.

“These disparities are not because Black people are inherently less healthy,” said Rhonda Smith, executive director of the California Black Health Network. “They are the result of decades of inequitable policies, structural racism, unequal access to quality care, and chronic underinvestment in our communities.”

Dr. Flojaune Cofer, an epidemiologist and public health policy expert, said health outcomes are shaped as much by circumstances as by biology. She traced her understanding of disparities to her father’s death from heart disease at age 47. He began smoking as a child when tobacco companies marketed cigarettes aggressively and disproportionately to Black communities.

“My father’s story is not about individual choices,” Cofer said. “My father’s story speaks to institutional and systemic harm.”

“Health is not just what happens in the doctor’s office,” she added. Social determinants include neighborhood conditions, housing stability, nutritious food, transportation, and the ability to take time off work for care.

At federally qualified health centers, tight appointment schedules can make it difficult for medical providers to detect cancer early and earn the trust patients need to discuss troubling symptoms.

“We have only 15 minutes when you are working in a federally qualified health center — you have 15 minutes to assess, diagnose, treat, and write your note per patient,” said Jamie Garcia, a registered nurse who has been certified in oncology nursing for more than a decade and works at AdventHealth White Memorial in East Los Angeles.

Garcia said the rushed pace, driven partly by billing requirements tied to federal funding, leaves little time for providers to build relationships with patients. It can also allow health care professionals’ implicit biases to go unrecognized and unchallenged.

For Garcia’s patients, who are predominantly Black and Latino residents of surrounding communities, the consequences can be immediate and alarming. Many arrive with visibly advanced tumors after going without insurance, adequate coverage, a primary care physician or routine screenings.

Garcia recalled treating one patient whose tumor had grown large enough to be visible through the skin.

“The fact that I even got to see that is a failure and an atrocity,” she said.

Assemblymember Lori D. Wilson (D-Suisun City) sought to reduce another barrier through Assembly Bill 1570, which would have eliminated out-of-pocket costs for medically necessary diagnostic and supplemental breast imaging. It passed the Assembly Health Committee 16-0 but died in the Appropriations Committee. Wilson plans to reintroduce it during the next legislative session without biopsy coverage.

Wilson announced her breast cancer diagnosis in April 2023. She received timely, quality care but “saw others with similar diagnoses face different outcomes.”

“Some people who got diagnosed at the same time as me — their timing of their surgeries and treatment was delayed in comparison to my own,” she said. “Watching people go through and suffering unnecessarily was heartbreaking to me.”

Her follow-up imaging required only a $10 copay. “I’ve had friends have to pay $1,000 to get that secondary screening,” Wilson said.

Smith warned that policy changes could further erode access. California’s Every Woman Counts screening program is losing funding and being scaled back, she said. About one in three Black Californians relies on Medi-Cal, according to the state.

Smith also cited federal Medi-Cal work requirements projected to cause 1.1 million Californians to lose coverage by 2029-30. “Health equity is no longer simply about improving outcomes,” she said. “It’s about protecting access.”

Californians seeking low-cost cancer screening can contact a local federally qualified health center or the California Department of Public Health’s Every Woman Counts program. The California Black Health Network also offers referrals and advocacy resources.

JPMorganChase Expands San Francisco Housing Investments Under $750 Billion Initiative

OAKLAND POST — In San Francisco, JPMorganChase will provide nearly $200 million in financing for a 342-unit residential building at the Power Station development in the Dogpatch neighborhood. The firm previously financed the Sophie Maxwell Building at the site, which opened in 2025 with 105 permanently affordable apartments for middle-income residents.

JPMorganChase is expanding its housing investments in San Francisco, committing nearly $200 million to a new residential development and millions more to affordable housing projects, research and community organizations working to address the city’s housing shortage.

The San Francisco effort is part of the firm’s American Dream Initiative, through which it plans to deploy more than $750 billion nationwide through 2035 to increase housing supply and support homeownership. The commitment represents a nearly 40% increase over its housing investments during the past decade.

In San Francisco, JPMorganChase will provide nearly $200 million in financing for a 342-unit residential building at the Power Station development in the Dogpatch neighborhood. The firm previously financed the Sophie Maxwell Building at the site, which opened in 2025 with 105 permanently affordable apartments for middle-income residents.

The company also plans to invest up to $15 million in Fifth Space’s new Essential Housing Fund, which will support affordable housing development in San Francisco, including an expected 250 units in Potrero Hill.

“Too many families are struggling to make rent in San Francisco, and our administration is working every day to help them stay here. Building housing is a critical piece of that work, and we’re taking an all-hands-on-deck approach to make that happen,” said Mayor Daniel Lurie. “JPMorganChase’s investment in housing reflects their commitment to San Francisco’s future, and these projects with hundreds of new homes show what we can do when the private sector and the city come together to tackle the issues that matter to families.”

Another $6 million in grants will go to the San Francisco Housing Accelerator Fund, Community Vision Capital & Consulting, San Francisco Bay Area Planning and Urban Research Association, the Housing Action Coalition and Housing California. The firm will also support housing research by the Urban Land Institute Foundation, Terner Labs and other institutions to develop local policy recommendations.

Nationally, JPMorganChase aims to finance the construction or preservation of 1 million affordable housing units for households earning less than 120% of area median income. It also plans to help 500,000 customers, including 200,000 first-time buyers, purchase homes by increasing mortgage lending by more than 40% and hiring 850 home lending advisers.

“JPMorganChase has a decades-long history of supporting San Francisco’s housing ecosystem—working with developers, community organizations, and local government to help bring more housing to market,” said Noah Wintroub, global chair of J.P. Morgan. “Through the American Dream Initiative, we’re ready to do even more. With the right public policies in place, the firm can provide more capital for housing, scaling solutions that help expand supply and affordability.”
