First detections of many significant invasive insects have been made by members of the public. In the case of the first-ever observation of Asian longhorned beetle (Anoplophora glabripennis) in the United States, a resident of Brooklyn, New York, noticed unusual damage on maple trees in his neighborhood in 1996. He then caught an adult beetle, which he reported and provided to the New York City Department of Parks and Recreation. Since then, 12 additional infestations of the invasive forest pest have been found in North America, and a member of the public was the first detector in two-thirds of those cases. Public observations have also initiated discoveries in recent years of the elm zigzag sawfly, spotted lanternfly, boxtree moth, northern giant hornet, yellow-legged hornet, emerald ash borer, and Jorō spider.

Annapolis, MD; November 18, 2024—The next time you see an interesting bug, take a photo on your smartphone, and post it online. You just might catch an invasive species new to your area.

That's the call to action a group of entomologists are issuing to the public, in conjunction with advice to fellow scientists to monitor public observations, in a new article published this month in Environmental Entomology. Platforms like iNaturalist, Observation.org, and others allow users to post images of animals and plants with no prior knowledge of the potential importance or impact of what they're seeing, and experts within the fellow user community can provide identifications. Such "passive surveillance" is playing an increasingly common role in early detection of invasive species.

"More people involved will create more raw observations, and more raw observations increase the probability of early detection of something important," say the authors Amanda D. Roe, Ph.D., of the Canadian Forest Service; Leigh F. Greenwood, of The Nature Conservancy; and David R. Coyle, Ph.D., of Clemson University.

They call it "catching invasives with curiosity." And, indeed, even before the advent of smartphone-enabled nature observations, first detections of many significant invasive insects were made by members of the public. As Roe and colleagues explain, in the case of the first-ever observation of Asian longhorned beetle (Anoplophora glabripennis) in the United States, a resident of Brooklyn, New York, noticed unusual damage on maple trees in his neighborhood in 1996. He then caught an adult beetle, which he reported and provided to the New York City Department of Parks and Recreation. Since then, 12 additional infestations of the invasive forest pest have been found in North America, and a member of the public was the first detector in two-thirds of those cases.

Public observations have also initiated discoveries in recent years of the elm zigzag sawfly, spotted lanternfly, boxtree moth, northern giant hornet, yellow-legged hornet, emerald ash borer, and Jorō spider.

The community of scientists and professionals who work to detect and respond to invasive species use a variety of tools and strategies, many of them highly targeted or reliant on trained experts. But public observations are a key piece of the puzzle—perhaps especially so for insects. "Passive surveillance does not replace active surveillance for invasive species; rather, it widens the surveillance net, substantially augmenting and broadening existing biosecurity frameworks," Roe and colleagues write.

They report that some entomologists are already building informal methods for monitoring public biodiversity observations through existing applications, and the authors recommend that scientists and government agencies invest in building more integrated alert systems, codify data-mining efforts, and communicate that they are following ethical frameworks when using public data. Research and experience from past invasive species incursions have shown that, the earlier an arrival is detected, the better the chances of containing or eradicating the invasive species—thereby decreasing impacts on ecosystems, the economy, and human health.

For people who want to get involved, iNaturalist is the world's largest platform for public biodiversity observations and is the leading North American system. Observation.org is a strong alternative, and more commonly used in Europe. Meanwhile, BugGuide.net focuses specifically on insects and arthropods. And, in the U.S., many university extension programs offer insect identification services, as well.

If members of the public answer the call to share more insect and arthropod observations of all kinds, entomologists must be ready to use them, Roe and colleagues say.

"Increasing the number of observers (and observations) will ultimately improve invasive species surveillance," they write. "So the invasive species surveillance community should strive to develop a holistic approach to biosecurity that fully embraces the curious public as invasive species early detectors."

While invasive alien species have long been recognised as a major threat to nature and people, urgent action now is needed to tackle this global issue. This is the critical evaluation by the 88 authors, representing 101 organisations from 47 countries, of ‘Curbing the major and growing threats from invasive alien species is urgent and achievable’ published in Nature, Ecology & Evolution, including lead author Professor Helen Roy from the UK Centre for Ecology & Hydrology and the University of Exeter.

Focused on the main findings of the Intergovernmental Science Policy Platform on Biodiversity and Ecosystem Services (IPBES) thematic assessment report on invasive alien species and their control*, the paper also highlights that the impacts of invasive alien species observed today are likely to underestimate the magnitude of future impacts. Also, the interactions among biodiversity drivers are key as no driver acts in isolation.

Co-chair of the IPBES IAS assessment and lead author, Professor Helen Roy from the UKCEH and the University of Exeter, said: “The paper brought together the entire expert team of the IAS assessment, with this diverse group spanning many disciplines with perspectives from around the world drawing the same conclusion about the need for urgent action on the major and growing threat of invasive alien species.

“With the number of invasive alien species set to rise, the IPBES invasive alien species assessment provides the evidence-base and options to inform immediate and ongoing action. To achieve this there is a need for collaboration, communication and cooperation, not only across borders but within countries.”

Professor Peter Stoett from Ontario Tech University, co-chair of the IPBES IAS assessment, added: “Interdisciplinarity is key to the success of IPBES assessments. It was wonderful to see social science and humanities experts interacting with invasion biologists and other natural scientists, in a community-building process that will inform policy decisions moving forward.”

The threats posed by invasive alien species are expected to continue to rise. Every year, approximately two hundred new alien species are now being introduced globally by human activities to regions they had not been recorded before. Even without the introduction of new species by human activities, already established alien species will continue to naturally expand their geographic ranges and spread into new countries and regions, with many causing negative impacts. Simple extrapolations from the impacts of invasive alien species observed today are likely to underestimate the magnitude of future impacts.

Interactions among drivers of biodiversity loss are amplifying biological invasions with no driver acting in isolation. Climate change is a major driver facilitating the establishment and spread of invasive alien species into previously inhospitable regions. For example, climate warming is enabling aquatic and terrestrial invasive alien species to establish and spread poleward, including into the Arctic and Antarctic regions. Also, in some mountainous regions, climate change, acting together with other drivers of biodiversity loss, has allowed invasive alien species to extend their ranges into higher elevations twice as fast as native species.

The IPBES invasive species assessment provided the first comprehensive synthesis of evidence globally concluding that the threat of biological invasions is major but can be mitigated with urgent cross-sectorial cooperative and collaborative action. Co-developing management actions with multiple stakeholders including government and private sector stakeholders, and Indigenous Peoples and local communities will be critical to achieving success in addressing biological invasions.

Aníbal Pauchard, co-chair of the IPBES IAS assessment and Professor at the University of Concepción, Chile, highlights the importance of inclusion within the assessment: “This is not only the most comprehensive global assessment on invasive alien species to date, but also the selection of experts and the evidence gathering was done under the highest standards of inclusivity, resulting in a report which provides critical insights for all stakeholders.”

Coordinating bodies such as the Non-Native Species Secretariat can ensure effective collaboration among diverse stakeholder groups. Indeed, management actions in response to incursions of the Asian hornet (Vespa velutina) in the UK have involved multiple stakeholders coming together to ensure rapid flow of information following detection of the species leading to effective control of nests.

The paper recognises that the engagement of the general public through awareness raising campaigns, education and community science platforms also contributes to establishing shared responsibilities in managing biological invasions. Community science initiatives, supported by digital identification tools are important for the rapid detection of invasive alien species. Records submitted by the public through the Asian Hornet Watch app in the UK are making a major contribution to Vespa velutina (Asian hornet) early warning and rapid response.

City of Alameda Halts Climate Tech Experiment Aboard a WWII Carrier

The Cloud-Aerosol Research Instrument aboard USS Hornet (UW Marine Cloud Brightening Program)

The City Council in Alameda, California has put an end to a scientific experiment aboard the WWII carrier USS Hornet, a museum ship permanently berthed at Old Alameda Point. 

Last year, a team of researchers from the University of Washington and funders at nonprofit SilverLining arranged to use the deck of the Hornet to test a cloud-brightening machine - a device designed to emit aerosols that promote water droplet formation and create reflective white clouds, partially shielding a small area from the sun's heat. Their plan was to put the small nozzle-like device aboard Hornet, run it for up to a year and collect data on how well it worked outside of the lab. As a test-size model, it is not expected to have measurable local effects, and its emissions are below the minimum threshold for environmental permitting.

However, some of Alameda's citizens objected to the testing, for two separate reasons. First, some residents expressed concern that the mist could have health effects. In early April, the city of Alameda ordered the experiment paused until it had further information on the impact on health and safety. After a brief period of research, the city managers determined that the tests did not post any measurable risk to the health of the surrounding community or wildlife, since the contents of the device's spray were naturally-occurring and similar to seawater. 

The second reason is more complex, and reflects a matter of disagreement in the environmental community. Cloud brightening is a form of geoengineering - a deliberate intervention to slow down warming, whether or not humanity stops emitting large amounts of carbon. Some climate action groups oppose geoengineering on principle, arguing that it creates an excuse for inaction on carbon and uses up funding that could be spent on developing green energy alternatives. It could also have unpredictable consequences for natural ecosystems. 

Researchers in the geoengineering field argue that it may be needed as a backup if the world's nations fail to follow through on their Paris commitments, and could help mitigate the impact of an already-changing climate on the developing world. If used at massive scale - for example, on thousands of oceangoing vessels - it could have a meaningful global impact. 

This week, the Alameda City Council decided that it would not be taking any chances with the project. On Wednesday morning, the five council members voted to prohibit further testing aboard USS Hornet, despite the report from their staff advising that the process was safe. Among other issues, the council was concerned that its members had never been informed, and that local leaders found out about the project after the fact from media reports. 

"Was it intentional? Was it an oversight?" Alameda Mayor Ezzy Ashcraft said, speaking to the East Bay Times. "The experiment was shrouded in secrecy, then it turns out it was in a controversial field."

Project leaders have denied any attempts at secrecy, and they emphasized that they had set up the test in an open, public space - USS Hornet, which they described as "unparalleled in its potential to increase access and equitable engagement for all people."

Hornets found to be primary pollinators of two Angelica species



New research overturns the conventional belief that Angelica species do not have a primary pollinator

Researcher Ko Mochizuki of the University of Tokyo discovered that two species in the genus Angelica are pollinated primarily by hornets. This overturns the conventional belief that Angelica species are “generalists,” meaning that there is not one primary pollinator but a variety of species. As hornets are rarely primary pollinators, the discovery also impacts future ecological research and conservation efforts. The findings were published in the journal Ecology.

White, small, open, secretes nectar and produces pollen: these are the kinds of flowers that many types of insects can reach and are attracted to. Most of the plants in the carrot family, Apiaceae, fit this description perfectly. As such, the species in this family are considered to be generalists. In extreme cases, over 100 different insect species visit their flowers. Not so with Angelica decursiva and Angelica hakonensis, two species in the genus Angelica in the family.

“I observed a fierce visitation by hornets for the first time in 2015 in Nagano Prefecture,” Mochizuki recalls, “and then again in 2018 in the Nikko Botanical Garden where they were feeding on the nectar of the inflorescences of A. decursiva and A. hakonensis. Since it was a dogma that species in the family Apiaceae are generalists, this observation motivated me to investigate if the two Angelica species were pollinated predominantly by hornets.”

Confirming the hunch was a stepwise process. First, Mochizuki returned to the Nikko Botanical Garden to quantify the numbers and types of "visitors" to the flowers. Then, he captured some visitors to check the amount of pollen stuck to their bodies to verify whether it would be enough for pollination. Finally, he conducted an experiment in which he covered some flowers with a mesh that blocked the hornets and some flowers with a mesh that blocked all insects, with a third group of flowers remaining uncovered as the control group. All three of these methods showed that hornets were the most numerous species that visited the flowers.

“Nevertheless, excluding hornets resulted in seed production higher than expected. I think excluding the hornets allowed other visitors to gather on the flowers. Especially considering that I had previously observed hornets hunting and killing other insect visitors when they encountered each other on the inflorescence,” Mochizuki explains.

Science advances by incremental steps. Discovering that hornets are the primary pollinator of certain species is one such incremental step, but the consequences are wide-ranging.

“Hornets are generally considered pests in their native range and problematic invasive species in some areas such as North America. Nevertheless, this study underscores the importance of hornets as pollinators, opening new avenues for research and conservation,” says Mochizuki.

Three-Day Sanders Institute Event Details the Case: 'Housing Is a Human Right'

"We can't address the housing crisis by chopping the weed off at the top. We have to pull it out by the roots," said one panelist at the intimate event in Los Angeles that looked at the issue from the local, state, and federal level.

COMMON DREAMS

We want to educate the public. We want to shift the narrative. We want to organize for transformational and lasting change.

Those were the stated goals and repeated themes at the heart of a three-day event in Los Angeles over recent days, a gathering focused on the national housing crisis organized by the Sanders Institute, spearheaded by co-founder Dr. Jane O'Meara Sanders and executive director Dave Driscoll.

While the policy discussion around housing has a reputation for being dynamic and complex—especially as an issue that straddles municipal, state, and federal governance—the human story at the center of what it means to have a home or be housed is simple and universal, a thread woven into over a dozen panels, presentations, and keynote speeches by progressive lawmakers, top experts, frontline advocates, academics, and community organizers.

In a conversation with Common Dreams, Sanders and Driscoll explained that everyone who attended the event—kept intentionally small and low-profile—was told that the focus would be on "concrete remedies" and "replicable policies" with the ultimate purpose of informing a national audience about not only how severe the housing crisis has become, but also the concrete ways to address it.

"We believe democracy requires an informed electorate and civil discourse and bold ideas. That's part of our mission," Sanders said. "And the purpose was to come at the housing crisis from many aspects—not all of the aspects, but many of them—with the goal of actionable solutions."

"None of us are very interested in making small incremental change, which might mean building some more affordable housing or supporting this or that initiative. That's not what this is about." —Dr. Jane O'Meara Sanders, The Sanders Institute

But why housing? Why now? According to Sanders, the issue is potent politically because it's an issue that is not just about the poor and unhoused, but also central to the working class.

"Everybody knows somebody that has a problem getting affordable housing or just affording their life and having to make different choices," she told Common Dreams. "It's middle-income people, it's everybody having a problem with the housing crisis, and elected officials are getting pressure. Those lawmakers and politicians are hearing it more and more. And we said, okay, now's the time to bring people together around this."

Driscoll targeted private equity, Wall Street investors, and real estate developers that have used their outsized economic and political power to further skew the nation's housing market in search of ever-larger profits, squeezing out low- or middle-income individuals and families in the process.

"It's just another way in which the gap is growing between the rich and the poor and increasing inequality," said Driscoll. "And that needs to stop."

It is powerful interests most of all, says Michael Weinstein, president of the AIDS Healthcare Foundation (AHF), who must be named, shamed, and overcome if any of the progressive solutions championed at the gathering—including rent control, social housing models, community land trusts, more climate-resilient communities, and proven efforts to curb homelessness—are to have any hope of being implemented at the necessary scale.

Weinstein—a driving force behind the event, a supporter of the Sanders Institute, and a major player in California's healthcare and housing political landscape—agrees fully with Sanders and Driscoll that the moment, both in California and nationally, is ripe for an invigorating politics focused on housing.

Rent Control for All

During opening remarks focused on "perpetually affordable housing" and a 2024 ballot initiative in California that would end the state's existing ban on local rent control ordinances, Weinstein said that he has argued for years that "the housing issue was not high enough on the progressive agenda."

"This is a battle for the poor and working-class people in California," Weinstein said of the Justice for Renters campaign, an effort funded by AHF, local unions, and others to see the Justice for Renters Act become law via a ballot measure this year.

"There are 17 million renters in California—that's 45% of the population," he explained. "There are tens of millions more renters across the country. Our primary job as progressives is to improve the lives of people and housing is their greatest need."

If enacted, the law would remove the existing ban on rent control laws in California, encourage expanded rent control at the local level, and curb the power of "predatory landlords" who charge "unfair and unaffordable" rent.

While everyone at the gathering agreed more housing stock is a key part of the solution, Weinstein was among those who emphasized that the biggest obstacle is unaffordability of homes and rental units—a problem attributable to the greed of landlords and the investor class within an economy designed to siphon the wealth of workers into the coffers of the already rich.

"We can't address the housing crisis by chopping the weed off at the top. We have to pull it out by the roots," Weinstein explained. "And high rents are the root cause of the housing affordability crisis. It's that transfer of wealth that's causing the problem. And if we do nothing about rising rents, then nothing else we do in terms of producing housing or other changes will make a difference. If we continue to treat housing as a commodity, we'll never be able to house everyone. It's very similar to healthcare. If we leave it up to the marketplace, we're lost."

With the homeless population in Los Angeles estimated to be over 70,000—in a city of approximately 3.9 million—Weinstein said that L.A. is "not just the homeless capital of this country" but the "homeless capital of the world." This, he lamented, is "truly shameful," but also the reason why California has a vital role to play in showing people that the crisis can be confronted.

As a veteran healthcare advocate and the head of a nonprofit organization focused on AIDS, Weinstein rejected the accusation he sometimes receives from political opponents that he is somehow "out of his lane" by pushing so loudly and aggressively for rent control reforms. One reason that assessment is wrong, Weinstein explained, is that housing is the largest predeterminant of health, which is also why so many at the gathering rallied around the demand that housing be treated like the human right it is.

"But the main reason I'm involved in housing," Weinstein told the audience at the gathering, "is that I feel the same outrage about the housing situation and homelessness today as I did in the 1980s about AIDS, where the benign neglect saw tens of thousands of people die needlessly."

In his remarks, Weinstein stressed the crisis is a result of the most powerful in society refusing to meet the needs of its most vulnerable. But he said the galvanizing potential of housing—and the political potency and opportunities of social uplift embedded in the solutions presented at the conference—must be recognized.

"This is a cry for unity," he said. "Unity behind rent control and unity behind opposing corporate real estate and unity behind housing justice. There's no better time than now."

Putting the Housing Crisis at the Top of the Agenda

The sense of urgency felt by attendees of the event was unmistakable.

Speaking at the opening night dinner for the conference, Rep. Jimmy Gomez (D-Calif.), who represents parts of Los Angeles County, said the creation of the Renters Caucus in Congress last year is a sign that lawmakers are beginning to take housing more seriously at the federal level.

The goal of the new caucus, Gomez said, "is to make sure that the renters agenda is at the top of the Democratic Party agenda." This was a focus of all the members of Congress who attended the gathering in some capacity, including Reps. Pramila Jayapal (D-Wash.) and Ro Khanna (D-Calif.) as well as Sen. Bernie Sanders (I-Vt.), also notable as Jane's husband. Driscoll is their son.

"Housing Should Be a Human Right in the Richest Country in the History of the World"

Democratic Los Angeles Mayor Karen Bass, who left Congress to provide more local leadership, said she did so because she saw that the rightward political shift at the local government level was set to take the city backward on a numerous fronts, including on the issues of affordable housing, education, and homelessness.

Calling housing "one of the most important issues of our lifetime right now," Bass praised the Sanders Institute's focus on the crisis and for bringing the event to California. "I know that you are going to be the brains behind what we need, which is a national movement," said Bass. "That's the only thing that is going to bring about the type of fundamental change that we need."

"What we need... is a national movement." —Los Angeles Mayor Karen Bass

Speaking after Jayapal—who had told the audience the battle for better housing policy in the United States should be viewed much like the battle for universal healthcare—Bass acknowledged there are things on the housing agenda that will require action by leaders at every level of government.

"But nothing takes the place of the grassroots day-to-day organizing that is needed," she said, "so that we can win what Pramila said: Housing should be a human right in the richest country in the history of the world, just like healthcare should be a human right."

According to Sen. Sanders, who delivered the keynote address and was an active participant throughout, the purpose of the gathering was to get beyond talk in order to get down to the real work of making change.

"Our task is to organize and to educate," Sanders said. "It's easy to come up with rhetoric—which I have done once or twice in my life—but when you're the mayor of a city, you're going to need some concrete plans. How do you do it? You're going to have to bring a lot of smart people together to figure out the best way forward."

Social Housing: A Solution That Works

A constant theme at the event was that not only does the housing crisis demand progressive solutions, but the implementation of those solutions are themselves opportunities to revive democracy, increase social cohesion, and expand the public imagination.

In their joint presentation on social housing, California Assemblymember Alex Lee (D-25) and South San Francisco Mayor James Coleman, also a Democrat, detailed a vision for "social housing" which aims to demolish preconceived notions that tend to dominate understandings of "public housing" throughout the United States.

When it comes to defining the term "social housing," Lee explained that he likes to "keep it simple." Social housing, he said, "is beautiful, sustainable, and publicly led developed housing that is available to everyone and for everyone."

The idea of universality, he emphasized, is critical in the U.S. context where public housing is typically subsidized housing only for low-income individuals or families. Social housing models across the world provide housing across economic classes, which creates more buy-in from communities and residents.

"There's a very deliberate reason of why we stick to the term social housing," Lee said, "even though it is three letters away from a scary thing that Americans fear." But it is the term used around the world, he explained—both in highly capitalistic economies like Singapore's as well as in the various social democracies of Europe and beyond.

Because it's housing for everyone—the poor, the middle class, and even the upper-middle class—Lee and Coleman explained that "universality" and the lack of means-testing are core components of a model they believe can transform people's understanding of what's possible in this country.

"With social housing," argued Coleman, "you'll see broad spots of the public be able to look at it and say: 'That is quality housing. I want to live there. I want my children to live there and I know I'm going to be paying lower rents than market rate.' And when people start seeing that, then they're going to want to continue to invest in social housing and we won't see the decades of disinvestment that we have seen here in the United States for our public housing program."

In an interview with Common Dreams, Lee offered a parallel example.

"In America," he said, "there is no constitutional guarantee of education, yet every parent will wake up tomorrow not having a single doubt in their mind that their child will go to school." Lee acknowledged not all children go to the same kinds of school, but said that people never doubt that education will be there for their families.

"But there is not the similar sense of options in housing—people don't have that." But they should, he said, and there are models out there—not just abroad but also examples in the U.S.—that show how it could work.

Citing housing construction in the post-war years, Lee said the country has shown it's capable of amazing things when it comes to housing.

"We could end the housing crisis in four years, at true scale," said Lee. "That's why it's really important to prove that this can work at the state level, especially in a state as populous as California. If we prove the concept here, we can show nationally how it can be done."

Like the Housing Crisis, "The Climate Crisis Is Actually a Massive Health Crisis"

During another session, actor and activist Jane Fonda presented alongside local activist Nalleli Cobo, a cancer survivor who has been fighting the oil industry that operates drilling wells in her urban neighborhood since she was a child.

Cobo, co-founder of the South Central Youth Leadership Coalition and a 2022 Goldman Environmental Prize winner for the activism that she initiated while still a teenager living in South Los Angeles, told the audience that the hard-fought victories she and her allies were able to win against the fossil fuel industry "were made possible because of a frontline community that was historically viewed as silenced, invisible, and disposable finally said: 'Enough is enough. We deserve to open our windows and our home and we deserve to breathe clean air.'"

"This is the largest crisis humanity has ever faced. We're running out of time and we have to fight back." —Jane Fonda

Living her whole life in a home neighboring a fossil fuel operation beset Cobo with health challenges throughout her childhood and ultimately led to a cancer diagnosis. Now three years in remission, she said affordable and healthy housing is something that every single member of society is entitled to.

"They may not be drilling in your community right now, but they can be unless we stand up and fight back," she said.

With nearly 3 million Californians living within a mile or less from oil and gas drilling wells, Fonda championed the courage and determination of Cobo to end this toxic practice, including with a ballot fight in California this year to ban such operations permanently.

"What Nalleli didn't tell you," Fonda told the audience when she took the podium, "is that at age 10 and 11, she and her mother had to be put into a witness protection program because of her organizing in the community to shut the oil well down; that at 19 she had to have a total hysterectomy; that her dream was to be a dancer and now that is no longer possible for her."

People must understand, Fonda said, that "the climate crisis is actually a massive health crisis" for people living in communities made toxic by fossil fuels all over the country and around the world. A cancer survivor in her own life, Fonda said she was told by someone when she threatened to tattoo the phrase "climate emergency" on her bald head if the chemotherapy took her hair that "the cancer community doesn't like to be looped in with other causes."

"Causes?!" she recalled exclaiming in response. "Honey, the climate crisis is not a cause. This is the largest crisis humanity has ever faced. We're running out of time and we have to fight back."

Climate Resilience and Housing Justice

Also on the climate front—which highlighted the intersectional style of the Sanders Institute's gathering—Congresswoman Jayapal joined with author and labor organizer Saket Soni as well as Jamie Court of the California-based Consumer Watchdog, an advocacy group, to discuss the linked issues of community resilience amid extreme weather disasters and soaring insurance costs that have arrived hand-in-hand with rising global temperatures.

While Soni in his work has been at the forefront of building up climate resilience in communities for decades—both by helping to mitigate the impact of extreme weather and also working on disaster relief and rebuilding—Jayapal explained that she has a bill in the U.S. House—called the Climate Resilience Workforce Act—that would formalize processes and establish funding to make such work a more integral part of federal, state, and local planning.

Among others, one component of the legislation would be to make sure that people in communities "disproportionately affected by climate change are actually at the table" when federal funds are dispersed.

According to the panel, the increasing impacts of climate change are a key driver of housing costs but nothing will get better without a justice lens through which to see the crisis of housing in an increasingly hotter world that is resulting in more floods, larger fires, and too little accountability for the corporate interests profiting from those extremes.

"In the context of our climate crisis," Soni explained during the panel discussion, "there is an opening for justice that Jayapal's bill is trying to take and that we're all trying to take. There is an opening where resilience is a framework that can accelerate housing justice, justice for the incarcerated, and justice for immigrants. And that's what we should all be trying to do, is look at how resilience is a real majoritarian framework—maybe one of the last ones left in our country—and inside of that there is so much consensus that we can push justice forward in many, many ways."

"There Is a Lot of Potential for Prop 1"

On the state level, California's Democratic Gov. Gavin Newsom arrived at the event to champion the recently approved measure known as Proposition 1, which will, among other things, provide state revenue from a nearly $6.4 billion bond to build and service more treatment beds for those experiencing severe mental health and addiction disorders as a way to curb homelessness across California.

During a panel discussion with Sacramento Mayor Darrell Steinberg and California Secretary of Health & Human Services Dr. Mark Ghaly, both Democrats, Newsom said that Prop. 1 would allow for a "strike force" that could better confront the overlapping issues of housing, homelessness, mental health, and substance addiction disorders.

Acknowledging the potential for hyperbole, Newsom said he believes what's contained in the new law "are the most significant" and far-reaching "behavioral health reforms happening anywhere in the United States of America."

While the debate over Proposition 1 was heated in the state, including among progressives who landed on various sides of the initiative, a subsequent panel focused on the implementation mostly landed on the side of cautious optimism for what it could be and what kind of model it might represent.

"There is a lot of potential for Prop 1," said Dr. Margot Kushel, professor of medicine at University of California San Francisco and director of the UCSF Benioff Homelessness and Housing Initiative.

"No matter where you stood on it before it passed," Kushel added, "there is a lot of potential now that it's here and we need to exercise that in the right way, which is that we need to be sure that it is used to enable these living-in-the-community, choice-driven, client-driven, but very supportive programs for people who are suffering terribly."

The evidence for what it will take to solve the mental health crisis as it pertains to homelessness, said Kushel, is overwhelming. "You don't need me to do more studies on it," she said, "we actually just need to bring to bear that funding [supplied by Prop 1] to solve some of these really sticky funding issues so that we can create the workforce, sustain the workforce, and create the programming" that will really serve the unhoused population "with dignity" in the communities they live in.

Several researchers presented on the severe impacts that homelessness and housing insecurity have on students and young people, including those in the foster care system. Other presenters described how community land trusts and other innovative housing collaborations, including faith-based initiatives, are providing models that could be replicated nationwide. Separately, a panel focused on the struggle of homeless veterans told the harrowing tale of former U.S. soldiers denied access to housing and care in Los Angeles who remain in a protracted legal fight with the U.S. Department of Veterans Affairs over land set aside for exactly that purpose.

In her reflections as a presenter and participant of the gathering, Congresswoman Jayapal explained to Common Dreams that the event was significant because "it lifted up an issue that" has been central for progressives but too often ignored and neglected by those in the media and within both major political parties.

"We don't suffer from scarcity in this country. We suffer from greed," Jayapal said. "We have enough money to house people, and to create situations where people aren't going to fear for what tomorrow's going to look like."


"We Need to Call Out the System"

The germination of the gathering, Jane Sanders explained to Common Dreams in the wake of the three days, was like "peeling back the onion" as one area of focus led to another, and a discussion with one invited expert resulted in the introduction to another.

As she realized the issue of housing was such a "hornet's nest" of intersecting issues, overlapping viewpoints, and innovative thinking, Sanders said it became increasingly clear that was exactly the reason to go forward with the event.

"We're talking about transformational change," she said of the work that she, Driscoll, and their colleagues are doing at the Sanders Institute. "None of us are very interested in making small incremental change, which might mean building some more affordable housing or supporting this or that initiative. That's not what this is about."

The Sanders Institute was initially in founded in 2018 with the goal of extending the energy, ideas, and political movement sparked during Bernie's presidential run in 2016. When the senator decided to run again in 2020, Jane and Dave decided to pause operations and then went into full hiatus when the coronavirus pandemic hit. In this context, holding an intimate housing conference in Los Angeles was conceived as a reawakening for the organization and a chance to let people know the time has now arrived to continue their original mission.

Reflecting on his experience after the gathering had concluded, Driscoll said it had been great to see so many people—whether in government or through an organization or at the grassroots level—having the chance to connect, learn from one another, and hopefully collaborate in the future.

"Sometimes this can be a lonely fight, whether or not you're fighting for housing or you're fighting for healthcare, sometimes you feel like you're not getting anywhere," he said. "But when you bring all these people together like we did over the last couple days, I felt at times a real energy in the room. People felt good about a really tough fight. So I think it inspired and fired people up, and also gave people hope for the future."

While they don't have it pinned down yet—that was the admission of the gathering—the point going forward is to clarify what the progressive agenda on housing should be and help push out to others how that fits into the broader movement for bold and lasting change.

When it comes to the opponents of such transformational proposals—national rent control, expansion of social housing, ending homelessness, or forging the Green New Deal for public housing—Driscoll said it's important that people understand powerful financial interests will fight such ideas with everything they have.

"We need to start calling people out like we did with tobacco money or with oil money," Driscoll said. "We need to start calling people out and saying, you're taking money from big real estate and developers that are causing this harm and stopping this progress." As is true in so many other areas of policy and politics, he said, following the money will be key in the battles to come.

"I don't like to call out individuals," Sanders said, "but we need to call out the system."

"It's a systematic problem that we don't say 'housing is a human right.' That's not shared in a capitalist society," she continued. "Not everybody would agree with that statement. We agree with that statement, but it's not one of those accepted truisms in this country. So what's our goal? That it become one."

AI helps to detect invasive Asian hornets

Artificial Intelligence can be used to detect invasive Asian hornets and raise the alarm, new research shows.

University of Exeter researchers have developed VespAI, an automated system that attracts hornets to a monitoring station and captures standardised images using an overhead camera.

When an Asian hornet visits, VespAI can identify the species with almost perfect accuracy – allowing authorities to mount a rapid response.

Asian hornets (also known as yellow-legged hornets) have already invaded much of mainland Europe and parts of east Asia, and have recently been reported in the US states of Georgia and South Carolina.

The UK sits at the edge of the European invasion front, and with ongoing yearly incursions there is an urgent need for improved monitoring systems.

“Our goal was to develop something cost-effective and versatile, so anyone – from governments to individual beekeepers – could use it,” said Dr Thomas O’Shea-Wheller, from the Environment and Sustainability Institute on Exeter’s Penryn Campus in Cornwall.

“This study tested a prototype version, and the results were encouraging. VespAI shows promise as a robust early warning system to detect Asian hornet ingressions into new regions.”

VespAI uses a compact processor to operate, and remains dormant unless its sensors identify an insect within the size range of a hornet.

If this happens, the system’s AI algorithm activates, analysing the image to determine if it’s an Asian hornet (Vespa velutina), or native European hornet (Vespa crabro). If an Asian hornet is detected, the monitor then sends an image alert to the user, allowing them to confirm the identification.

At present, the UK response strategy depends upon people seeing, identifying and reporting Asian hornets. However, this has some limitations.

“Unfortunately, the majority of reports submitted are misidentified native species, meaning that the responsible agencies have to manually validate thousands of images every year – our system thus aims to provide a vigilant, accurate and automated surveillance capability to remediate this,” said Dr Peter Kennedy, who conceptualised the system.

“In some parts of Europe, detection relies on hornet trapping – but such traps kill a lot of native insects, and do little to impact Asian hornet numbers.

“VespAI does not kill non-target insects, and thus eliminates the environmental impact of trapping, while ensuring that live hornets can be caught and tracked back to the nest, which is the only effective way to destroy them.”

During the project, the system was tested extensively on the island of Jersey, which experiences high numbers of Asian hornet incursions due to its proximity to France.

While this exposed the monitor to both Asian hornets, European hornets and a variety of other insects, VespAI’s detection algorithm successfully distinguished between each of these, even when present in large numbers.

“That’s the benefit of our system – its high accuracy means that it won’t wrongly identify other species, or miss any Asian hornets that visit,” said Dr O’Shea-Wheller.

The research project included both biologists and data scientists from the University of Exeter’s Environment and Sustainability InstituteCentre for Ecology and Conservation and Institute for Data Science and Artificial Intelligence.

This year, the team will begin deploying additional prototypes in collaboration with Defra, the National Bee Unit, the British Beekeepers Association and Vita Bee Health.

With 2023 seeing record numbers of Asian hornet sightings in the UK, the system aims to bolster exclusion efforts at a potentially crucial juncture.

“The proposed device may prove a powerful tool in the early determination of the presence of Asian hornets in an area, and thereby fills an important gap,” said Alistair Christie, Senior Scientific Officer for Invasive Species in Jersey, and part of the collaborative testing effort.

The project was funded by the Biotechnology and Biological Sciences Research Council (BBSRC), part of UKRI.

The paper, published in the journal Communications Biology, is entitled: “VespAI: a deep learning-based system for the detection of invasive hornets.”
