Appeals court ruling grants Donald Trump broad powers to deploy troops to American cities

Source: The Conversation – Canada – By Jack L. Rozdilsky, Associate Professor of Disaster and Emergency Management, York University, Canada

Residents of Los Angeles will need to get used to federally controlled National Guard troops operating on their streets. Due to a ruling from an appeals court on June 19, United States President Donald Trump now has broad authority to deploy military forces in American cities.

This is a troubling development. All presidents have held in their grasp extraordinary powers to deploy military troops domestically. But Trump stands apart with his apparent keen interest in manufacturing false emergencies to exploit extraordinary power.

An 1878 law called the Posse Comitatus Act restricts using the military for domestic law enforcement. The broader principle being challenged by Trump’s actions in L.A. is the norm of the military not being allowed to interfere in the affairs of civilian governance.

Injunctions and appeals

Five months into Trump’s presidency, L.A. has been targeted for aggressive immigration enforcement. In their pluralistic city where dozens of languages and nationalities peacefully co-exist, some Angelenos believe the city is experiencing an attack on its most essential social fabric.

On June 7, Trump acted under United States Code Title 10 provisions to take over command and control of California’s National Guard. Federalized military forces were deployed.

The objective was to counter what Trump argued was a form of rebellion against the authority of the government of the United States. In fact, these “rebellions” were largely peaceful protests in downtown L.A.

On June 9, the U.S. District Court for the Northern District of California granted an injunction restraining the president’s use of military force in L.A. The court order supported Gov. Gavin Newsom’s contention that Trump overstepped his authority.

On June 19, a decision from a panel of judges at the U.S. Court of Appeals for the Ninth Circuit overturned the injunction.

What this means at the moment is that Trump does not have to return control of the troops to Newsom. California has options to continue litigation by asking the Federal Appeals Court to rehear the matter, or perhaps directly asking the U.S. Supreme Court to intervene.

Moving toward authoritarianism

Trump’s June 7 memorandum facilitating his move to overrule Newsom’s authority and seize control of 2,000 National Guard troops was based on the president defining his own so-called emergency.

He claimed incidents of violence and disorder following aggressive immigration enforcement amounted to a form of rebellion against the U.S.

As Trump flexes his emergency power might, his second term has been called the 911 presidency. He has used extraordinary emergency powers at a pace well beyond his predecessors, pressing the limits to address his administration’s supposed sense of serious perils overtaking the nation.

Issues arise when the level of actual danger locally is not at all representative of what the president suggests is a full-scale national emergency. For example, demonstrations over immigration raids occupied only a tiny parcel of real estate in L.A.’s huge metropolitan area. A Los Angeles-based rebellion against the U.S. was not occurring.

As dissent over aggressive immigration enforcement actions grew, localized clashes with law enforcement did occur. Mutual aid surged into Los Angeles, where neighbouring California law enforcement agencies acted to assist one another. The law enforcement challenges never rose to the level of the governor of California requesting additional federal support.

Shortly after the federal government took over the California National Guard, Newsom said the move was purposefully inflammatory.

In addition to declaring dubious emergencies to amass power, stoking violence is a characteristic of authoritarian rulers. Creating fear, division and feelings of insecurity can lead to community crises. Trump did not need to wait for a crisis; it seems he simply invented one.

No guardrails

The expression “out of kilter” comes to mind as Trump inches closer to invoking the Insurrection Act of 1807. If so, the situation will look quite similar in practice to what is happening now in Los Angeles.

Five years ago, Trump flirted with invoking the Insurrection Act during Black Lives Matter unrest in Washington, D.C., in and around Lafayette Park.

As recent L.A. protests intensified, Trump stated: “We’re going to have troops everywhere.”

Currently, there are few guardrails in place to prevent a rogue president from misusing the military in domestic civilian affairs. Trump has been coy about whether he would tap into the greater powers available to him under the Insurrection Act.

Real emergencies presenting existential threats to America do persist. Nuclear proliferation, climate change and pandemics need serious leaders. But politically exploiting last-resort emergency laws designed to provide options to deal with genuine existential threats — not to weaponize them against protesters demonstrating against public policy — is absurd.

AI is consuming more power than the grid can handle — nuclear might be the answer

Source: The Conversation – Canada – By Goran Calic, Associate Profesor of Strategy and Entrepreneurship Leadership Chair, McMaster University

New partnerships are forming between tech companies and power operators — ones that could reshape decades of misconceptions about nuclear energy.

Last year, Meta (Facebook’s parent company) put out a call for nuclear proposals, Google agreed to buy new nuclear reactors from Kairos Power, Amazon partnered with Energy Northwest and Dominion Energy to develop nuclear energy and Microsoft committed to a 20-year deal to restart Unit 1 of the Three Mile Island nuclear plant.

At the centre of these partnerships is artificial intelligence’s voracious appetite for electricity. One Google search uses about as much electricity as turning on a household light for 17 seconds. Asking a Generative AI model like ChatGPT a single question is equivalent to leaving that light on for 20 minutes.

AI is bad for the environment, and the problem is bigger than energy consumption


Having GenAI generate an image can draw about 6,250 times more electricity, roughly the energy of fully charging a smartphone, or enough to keep the same light bulb on for 87 consecutive days.

The hundreds of millions of people now using AI have effectively added the equivalent of millions of new homes to the power grid. And demand is only growing. The challenge for tech companies is that few sources of electricity are well-suited to AI.

The grid wasn’t ready for AI

AI requires vast amounts of computational power running around the clock, often housed in energy-intensive data centres.

Renewable energy sources such as solar and wind provide intermittent energy, meaning they don’t guarantee the constant power supply these data centres require. These centres must be online 24/7, even when the sun isn’t shining and the wind isn’t blowing.

Fossil fuels can run continuously, but they carry their own risks. They have significant environmental impacts. Fuel prices can be unpredictable, as exemplified by the gas price spikes due to the war in Ukraine, and the long-term availability of fossil fuels is uncertain.

Major tech companies like Google, Amazon and Microsoft say they are committed to eliminating CO2 emissions, making fossil fuels a poor long-term fit for them.

This has pushed nuclear energy back into the conversation. Nuclear energy is a good fit because it provides electricity around the clock, maximizing the use of expensive data centres. It’s also clean, allowing tech companies to meet their low CO2 commitments. Lastly, nuclear energy has very low fuel costs, which allows tech companies to plan their costs far into the future.

However, nuclear energy has its own set of problems that have historically been hard to solve — problems that tech companies may now be uniquely positioned to overcome.

Is nuclear energy making a comeback?

Nuclear power has long been considered too costly and too slow to build. The estimated cost of a 1.1 gigawatt nuclear power facility is about US$7.77 billion, but can run higher. The recently completed Vogtle Units 3 and 4 in the state of Georgia, for example, cost US$36.8 billion combined.

Historically, nuclear energy projects have been hard to justify because of their high upfront costs. Like solar and wind power, nuclear energy has relatively low operating costs once a plant is up and running. The key difference is scale: unlike solar panels, which can be installed on individual rooftops, the kind of nuclear reactors tech companies require can’t be built small.

Yet this cost is now more palatable when compared to the expense of AI data centres, which are both more costly and entirely useless without electricity. The first phase of OpenAI and SoftBank’s Stargate AI project will cost US$100 billion and could be entirely powered by a single nuclear plant.

Nuclear power plants also take a long time to build. A 1.1 gigawatt reactor takes, on average, 7.5 years in the U.S. and 6.3 years globally. Projects with such long timelines require confidence in long-term electricity demand, something traditional utilities struggle to predict.

To solve the problem of long-range forecasting, tech companies are incentivizing power providers by guaranteeing they’ll purchase electricity far into the future.

These companies are also literally and financially moving closer to nuclear power, either by acquiring nuclear energy companies or locating their data centres next to nuclear power plants.

Destigmatizing nuclear energy

One of the biggest challenges facing nuclear energy is the perception that it’s dangerous and dirty. Per gigawatt-hour of electricity, nuclear produces only six tonnes of CO2. In comparison, coal produces 970, natural gas 720 and hydropower 24. Nuclear even has lower emissions than wind and solar, which produce 11 and 53 tonnes of CO2, respectively.

Nuclear energy is also among the safest energy sources. Per gigawatt-hour, it causes 820 times fewer deaths than coal, 43 times fewer than hydropower and roughly the same as wind and solar.

Still, nuclear energy remains stigmatized, largely because of persistent misconceptions and outdated beliefs about nuclear waste and disasters. For instance, while many public concerns remain about nuclear waste, existing storage solutions have been used safely for decades and are supported by a strong track record and scientific consensus.

Similarly, while the Fukushima disaster in Japan displaced thousands of people and was extremely costly (total costs of the disaster are expected at about US$188 billion), not a single person died of radiation exposure after the accident, a United Nations Scientific Committee of 80 international experts found.

With nuclear power on the rise, reducing conspiracies and increasing public education is key


For decades, there was little effort to correct public perceptions about nuclear fears because it wasn’t seen as necessary or profitable. Coal, gas and renewables were sufficient to meet the demand required of them. But that’s now changing.

With AI’s energy needs soaring, Big Tech has classified nuclear energy as green and the World Bank has agreed to lift its longstanding ban on financing nuclear projects.

Big Tech’s billion-dollar bet on nuclear

The world has long lived with two nuclear dilemmas. The first is that, despite being one the safest and cleanest form of energy, nuclear was perceived as one the most dangerous and dirtiest.

The second is that upgrading the power grid requires large-scale investments, yet money had been funnelled into small, distributed sources like solar and wind, or dirty ones like coal and natural gas.

Now tech companies are making hundred-billion-dollar strategic bets that they can solve both nuclear dilemmas. They are betting that nuclear can offer the kind of steady, clean power their AI ambitions require.

This could be an unexpected positive consequence of AI: the revitalization of one of the safest and cleanest energy sources available to humankind.

The Learning Refuge: How women-led community efforts help refugees resettle in Cyprus

Source: The Conversation – Canada – By Suzan Ilcan, Professor of Sociology & University Research Chair, University of Waterloo

A grassroots organization in Paphos, Cyprus, is bringing women together to address the needs of refugees in the city. (Shutterstock)

Since 2015, the Republic of Cyprus (ROC) has seen a steady rise in migrant arrivals and asylum applications, primarily from people from Middle Eastern and African countries like Syria, the Democratic Republic of Congo and Cameroon.

But many asylum-seekers face significant challenges. Refugees formally in the asylum system are often denied residency permits, which means they face persistent insecurity, poverty and isolation

These conditions are compounded by restrictive and limited services for asylum-seekers. This deepens the precarity and exclusion refugees face within a political and economic system that treats them more like economic burdens than as human beings with rights who need help.

In response to these institutional failures, citizens, volunteers and refugees themselves have begun to build grassroots networks of care and solidarity in the ROC and beyond to support refugee communities.

In 2022 and 2023, we conducted interviews with women volunteers and refugees affiliated with The Learning Refuge, a civil society organization in the city of Paphos in southwest Cyprus that cultivates dialogue and collaboration among these two diverse groups.

Women-led initiatives

Many displaced people first arrive on the island of Cyprus through the Turkish Republic of Northern Cyprus (TRNC). However, the absence of a functioning asylum system or international legal protections leaves them in limbo.

With no viable path to status in the TRNC, most cross the Green Line that bifurcates Cyprus into the ROC, where European Union asylum frameworks exist but remain limited in practice.

Women-led community-building is often a response to the negative effects of inadequate state support and humanitarian aid for refugees. In Cyprus, this situation leaves many refugees without access to sufficient food, satisfactory health care, accommodation, employment, clothing and language training. In this current environment, refugees are increasingly experiencing insecure and fragile situations, especially women.

In Cyprus, as in many other countries, a variety of community-building efforts are important responses to limited or restricted state support and humanitarian aid for refugees.

Women-led efforts offer opportunities to deliver educational activities and establish networks, and to help improve the welfare and social protection of refugee women, however imperfectly.

These and other similar efforts highlight how women refugees and volunteers can mobilize to foster dialogue and collaboration.

The Learning Refuge

Founded in 2015, The Learning Refuge began as community meetings in a city park. The organization then used space from a nearby music venue to conduct support activities, and later, established itself in a dedicated building.

Organizations like The Learning Refuge emerged to address the limited state support and humanitarian assistance services available to refugees.

As Syrian families began arriving in Paphos in 2015, local mothers started working with Syrian children, assisting them with homework, providing skills-training opportunities and language classes.

The Learning Refuge cultivates dialogue and collaboration among a diverse group of community volunteers, including schoolteachers, artists, musicians, local residents, refugees and other migrants.

With the aid of 20 volunteers, the loosely organized groups provide women refugees with material support and resources to enhance collective activities, including art and music projects, while also engaging in educational and friendship activities.

While modest in scale, the organization has formed partnerships with local and international organizations, including Caritas Cyprus, UNHCR-Cyprus and the Cyprus Refugee Council to extend its outreach to various refugee groups.

The organization has also launched creative initiatives aimed at cultivating additional inclusive civic spaces. One such effort, “Moms and Babies Day,” was developed in response to the rising number of single mothers from Africa arriving on the island. These women often face poverty and isolation, and struggle with language barriers.

These efforts highlight how grassroots responses — especially those led by women — can offer partial but vital educational and emotional support to refugees struggling to find their footing in a new country.

Negotiated belonging

Through participation in The Learning Refuge, refugee women in Paphos engage in a dynamic process of negotiated belonging, navigating challenges like language barriers, gendered isolation, domestic violence and poverty while contributing to broader community-building efforts.

For example, Maryam, a Syrian woman and mother of three, told us how The Learning Refuge helped her children establish friendships and learn Greek. She also highlighted that it helped her form close ties with volunteers and other Syrian women living in Cyprus, and find paid work in the city.

The volunteers and women refugees participating in The Learning Refuge’s activities emphasized not only their capacity to develop new forms of belonging and solidarity; they also help reshape communal knowledge and generate supportive spaces for women from various backgrounds.

Our research shows that women-led community-building is an effective, though short-term, response to insufficient state support and humanitarian aid systems that leave many refugees in precarious situations.

In varying degrees, these efforts offer women and their families spaces to learn and cultivate new relationships, and foster collective projects and better visions of resettlement and refuge.

Alberta youth have the right to school library books that reflect their lives, including sexuality

Source: The Conversation – Canada – By Jamie Anderson, PhD Candidate, Werklund School of Education, University of Calgary

Alberta Premier Danielle Smith has expressed fondness for Florida Gov. Ron DeSantis, most recently wagering a a friendly public bet on the NHL hockey playoffs. In 2023, she said she wanted Albertans to enjoy some of the same freedoms available to citizens in certain American states, including Florida.

Her government’s latest proposal aims to take more than a page from DeSantis’s playbook, setting its sights on how Florida has targeted school library books, effectively purging and banning many.

Alberta Education Minister Demetrios Nicolaides recently announced the province will move ahead to develop provincial standards “to ensure the age-appropriateness of materials available to students in school libraries.” This followed a public engagement survey related to what he said were concerns about “sexually explicit” books in Edmonton and Calgary schools.

The province says the survey results show “strong support” for a school library policy, even while the majority of respondents don’t want the government setting standards for school library books.

This marks the Alberta government’s latest effort to restrict the rights of 2SLGBTQIA+ children and youth.

New proposed school library standards

Like Florida’s statute on K-12 instructional materials, Alberta’s proposal centres on age-appropriateness and increasing parental choice in learning materials.

Despite claiming a need for new standards, Nicolaides has acknowledged there are already mechanisms in place in Alberta’s school jurisdictions for parents to challenge materials. Many school boards already have policies governing school library materials.

Additionally, librarians are trained professionals who follow established practices around organizing materials that reflect developmental appropriateness.

Florida school book purges

Florida’s statute, framed by DeSantis as empowering parents to object to obscene material, has targeted 2,700 books. More than 700 were removed from libraries in 2023-24.

Ron DeSantis shows how ‘ugly freedoms’ are being used to fuel authoritarianism


Confusion and a climate of fear caused by the bill has led Florida teachers and librarians to self-censor. Florida’s Department of Education urged districts to “err on the side of caution” to avoid potential felony charges.

Such fear and surveillance lead to unnecessary restrictions on students’ rights.

Targeting 2SLGBTQIA+ books

Nicolaides has emphasized that developing the new standards in Alberta is not a question of “banning certain books,” and has acknowledged he does not have that authority.

However, as PEN Canada notes, the implications of the proposed policies raise alarm bells, with the government’s actions “paving the way to a new era of government-sponsored book banning.” Singling out books has the same effect as a ban, according to the CEO of the St. Albert Public Library.

By labelling four books as inappropriate — three of which include 2SLGBTQIA+ authors and themes — Nicolaides suggests these books don’t belong in K-12 schools. One of the books, the graphic novel Flamer, has won several awards, including the Lambda Literary Award for LGBTQ Young Adult Literature in 2021.

PEN America interview with Mike Curato, author of ‘Flamer.’

The education minister refuted the idea that singling out the books is anti-queer or anti-trans, and did so in an inflammatory manner, characterizing concern as being about protecting children from seeing porn, child molestation and other sexual content.

Nicolaides also said the proposed policy is focused on sexual content, so themes and depictions of graphic violence are “probably not” an issue.

Rolling back trans, queer rights

Alberta has already rolled back the rights of trans and non-binary children and youth to use different pronouns, access gender-affirming care and participate in sports.

Queer and trans identities are also absent from all subjects in the K-12 program of studies, including recently updated K-6 curriculum. New sexual health resource guidelines prohibit the use of learning materials that primarily and explicitly address sexual orientation or gender identity unless they have been vetted and approved by Alberta Education (except for use in religion classes).

Survey amplifies moral panic

Through specific communication tactics, the minister’s public engagement works to exacerbate moral panics about sexuality as a threat to childhood innocence. This influences broader messages about 2SLGBTQIA+ inclusion.

The government-created survey shared illustrations and text excerpts on their own, without context or consideration of their narrative purpose in each book. Although the excerpts flagged by the minister make up between 0.1 to two per cent of the total page count in each book, the books as a whole are labelled “extremely graphic.”

In a media appearance, Nicolaides stated the books in question were available to “elementary-aged” students. This is misleading because K-9 schools include junior high students.

In a social media post, the minister’s press secretary said “these problematic books were found in and around books like Goldilocks,” suggesting targeted books are alongside children’s storybooks. But the image he shared showed Flamer near the graphic novel Goldilocks: Wanted Dead or Alive, aimed at middle-grade readers aged nine to 12 years old.

Survey respondents

The survey reported 77,395 responses by demographics, including parents, teachers, school administrators, librarians and other interested Albertans.

Forty-nine per cent of parents of school-aged children were not at all or not very supportive of the creation of government guidelines, compared to 44 per cent of the same demographic who were somewhat or very supportive (eight per cent were unsure). Across each other demographic, most respondents expressed that they didn’t support the creation of new government standards. But the ministry plans to move ahead anyway.

Socially conservative lobby

The Investigative Journalism Foundation reports two conservative activist groups have taken credit for giving the Alberta government names of books believed to be inappropriate.

Parental rights groups and far-right activists have long asserted that 2SLGBTQIA+ inclusion in schools “indoctrinates” and sexualizes children.

We’re concerned the Alberta government may be reinforcing this message to manufacture a greater public consensus in support of wider policies against 2SLGBTQIA+ rights.

Since at least 2023, United Conservative Party (UCP) members have embraced socially conservative “parental rights” rhetoric and supported motions for purging school libraries and mandating parent approval of changes to kids’ names and pronouns.

Traditionalist ‘parental rights’

Far-right activist groups like Take Back Alberta have shaped the UCP government’s policies alongside special interest groups like Action4Canada and Parents for Choice in Education.

A common thread among such groups is parental authority over one’s own children framed in traditionalist or hetero-normative terms. Significant mobilizing has happened against the inclusion of sexual orientations and gender identities in school curricula, trans-inclusive health care, drag shows, conversion therapy bans and more.

Pride, pages and performance: Why drag story time matters more than ever


Queer and trans identities are viewed as a social contagion threatening to change anyone exposed to them, and efforts for inclusion are labelled “gender ideology.”

These misconceptions, combined with political and religious biases, frame queerness and transness as “adult topics” that will confuse or harm children. However, research confirms ignoring these topics is of far greater concern when children may already experience discrimination about their gender expression by the age of five.

Earlier learning about diverse forms of gender expression and relationships can reduce victimization, and prevent young children from becoming perpetrators of, or bystanders to, anti-2SLGBTQIA+ harassment and violence.

‘Parental rights’ lobby puts trans and queer kids at risk


The United Nations recognizes that governments need to resist political pressure “based on child protection arguments to block access to information on [2SLGBTQIA+] issues, or to provide negatively biased information.”

Access to self-selected literature is important for all students, and can be a lifeline for 2SLGBTQIA+ students who don’t see themselves in the curriculum.

If Alberta Education will not prepare students for the world they live in — where we queer and trans people exist, flourish and are loved — then students should be able to seek out stories that reflect that world. It’s a matter of protecting their freedom of expression.

Indigenous engagement is essential for small modular nuclear reactor projects

With climate change-fuelled natural disasters becoming more frequent and devastating for communities around the world, the need for cleaner energy solutions is more urgent than ever.

When it comes to transitioning away from fossil fuels, much of the focus tends to be on solar, wind or hydroelectricity. However, small modular reactors (SMRs) are an emerging technology showing promise globally.

SMRs are a specific type of nuclear reactor that, as the name suggests, are small in energy output and modular in their manufacturing. Provinces like New Brunswick, Alberta and Saskatchewan have made progress on strategic plans to make SMRs part of their provincial climate action plans.

Unlike traditional nuclear reactors that generally produce more than 1,000 megawatts of electricity, SMRs are designed to produce as low as five megawatts. The modularity of such reactors allows for manufacturing off-site and installation at the desired location. This can decrease construction time, manufacturing costs and certain environmental costs associated with building on site.

This means SMRs are more feasible for many off-grid communities that lack reliable access to electricity, many of which are Indigenous. In 2023, the Canada Energy regulator said there were 178 remote Indigenous and northern communities not connected to the North American electricity grid and natural gas infrastructure.

In an effort to shift reliability from carbon-emitting resources to nuclear power, SMRs provide an exciting alternative, but implementation needs effective engagement with Indigenous communities to flourish.

Engaging Indigenous communities

Much of Canada’s electricity is already generated from low-carbon emission sources. However, there are still areas in northern Canada that are reliant on diesel, and therefore SMR plans are often aimed at providing electricity to these communities.

While on paper, this might sound like the perfect solution, there’s a lot to consider about SMR siting from an environmental perspective in these remote communities. These considerations include but are not limited to potential locations, source term, refuelling and waste management.

As research continues into the engineering and science behind SMR technology, meaningful community engagement with Indigenous communities is also required.

Thoughtfully considered and integrated consultations are necessary to ensure projects respect treaties, land rights and the surrounding environment. Consultation is needed to understand the needs and goals of the community for creating an energy transition plan.

In addition, incorporating traditional ecological knowledge in environmental risk assessments is vital. Ultimately, projects designed alongside Indigenous communities should strive for Indigenous sovereignty over growing infrastructure.

Why community engagement is important

Indigenous communities continue to face challenges as a result of colonization. The Truth and Reconciliation Commission’s (TRC) seventh Call to Action highlights the need to eliminate educational and employment disparity between Indigenous and non-Indigenous Canadians.

A direct way to address in terms of Canada’s nuclear landscape is to train members of those communities in technical roles related to the planning, deployment and sustained use of a nuclear facility. Specifically, training today’s Indigenous youth so they can fulfil these roles in their future careers.

The TRC’s Call to Action 92 calls on Canada’s corporate sector to engage in meaningful consultation, respectful relationship-building and equitable access to training and education opportunities that will contribute to long-term benefits from any economic development projects.

Through understanding the need for this relationship-building, there is a lot that western practices can learn from adopting Indigenous ways of knowing. Indigenous people have a long history of sustainable practices in their culture and traditions, and although western science now consider sustainable practices, it is not deeply woven into community and industrial initiatives.

As nuclear projects advance in Canada, it’s vital to respect Indigenous knowledge through weaving with western science. Projects can adopt a Two-Eyed seeing approach. This refers to viewing a problem with one eye using an Indigenous knowledge perspective and the other with a western knowledge lens. There is much to learn from understanding the philosophy behind Indigenous ways of knowing that can be applied to protect the environment.

Indigenous knowledge varies across Canada and comes with different insights, but a commonality is the teaching that all living things are interconnected and must be respected and cared for. This perspective is necessary for the future of nuclear projects to ensure the environment is sustained to support the biodiversity of regions throughout Canada.

This informed approach of protecting the environment, together with an ecosystem approach that considers the uniqueness and interconectedness of each organism, will ultimately lead to improved nuclear policies and safety.

The actions that institutions and private industry take today to build strong relationships with Indigenous communities and work towards an increasingly sustainable future will support already resilient communities so they can see growth well beyond the deployment of SMRs. A path to a cleaner future is in reach, but only if we walk beside Indigenous leaders, knowledge holders, community members and, especially, youth.

Catholic school board’s regressive flag policy sets back reconciliation in a post-Papal visit Canada

Source: The Conversation – Canada – By Erenna Morrison, PhD Candidate, Curriculum and Pedagogy, Ontario Institute for Studies in Education, University of Toronto

Following the release of the Truth and Reconciliation Commission’s 94 Calls to Action in 2015, some Catholic school boards have made commitments to reconciliation in education. These boards include the Dufferin-Peel Catholic District School Board (DPCDSB).

However, the DPCDSB — located in the Greater Toronto area — has also introduced a flag policy that raises serious questions about a commitment to the wider progress being made in welcoming all students and promoting reconciliation.

On Jan. 28, 2025 — following advocacy in different parts of Ontario and the country against the presence of the Pride flag — the board’s trustees voted in nine to one to add more restrictions to its flag policies. These restrictions stipulated that only flags representing Canada, the provinces, territories and the school board can be be displayed inside schools or other DPCDSB facilities.

Acts of erasure

The developments in Peel Region follow earlier policy changes to restrict the presence of the Pride flag and other flags at schools.

Advocates from the board defending flag restrictions have said that in Catholic schools, the icon of the cross is the only symbol that should be promoted and that this represents inclusion and acceptance of all.

However, members of the 2SLGBTQI+ community and opponents of restrictive flag policies argue that the Pride flag is needed to signal a welcoming environment. They say its removal is an act of erasure and that it calls into question how the board affirms the rights, dignity and visibility of 2SLGBTQI+ people and how it fosters their safety. The board says, and believes, its practices and policies comply with the Ontario human rights code, adding that supports are available for students who identify as 2SLGBTQI.

The erasure of the Pride flag has the simultaneous effect of banning other important flags, such as Every Child Matters flags, Indigenous Nation flags and MMIWG2S flags (drawing attention to ending violence, disappearance and murder of First Nations women, girls and two-spirit people).

In our analysis, this restrictive flag policy expresses colonial violence. We rely on the work of Sandra Styres, researcher of Iethi’nihsténha Ohwentsia’kékha (Land), Resurgence, Reconciliation and the Politics of Education, who examines how colonial violence is expressed in academic settings through “micro-aggressions, purposeful ignorance, structural racism, lateral violence, isolation” and also in “representations and spaces.”

Crucial time for righting relationships

Our concern is informed by our combined research and personal engagement focused around reconciliatory education in elementary Catholic schools (Erenna) and Anishinaabe Catholic expressions of self-determination in the Church (Noah). Erenna is a settler and Noah is a member of Michipicoten First Nation.

We are married writing partners who travelled to Québec City in July 2022 to witness the long-awaited penitential pilgrimage of the late Pope Francis. We left with an awareness that this is a critical time for the righting of relationships that have been severely fractured by a Church complicit in genocide.

The DPCDSB flag policy speaks to an unwillingness of many to sever emotional attachments to the white imperialism that preserves a western way of thinking, doing and being, in the name of faith.

When a major Catholic entity like the DPCDSB introduces policies that may cause harm, concerned people, regardless of creed, must pay attention to such injustices.

Revised flag policy

Delegate Melanie Cormier, representing the DPCSB’s Indigenous Education Network, shared a statement relaying that the board’s restrictive flag policy fails to acknowledge the Mississaugas of the Credit First Nation whose traditional and treaty territory where the board resides. She states: “Your flag policy is in violation of our jurisdiction. To say that any of our flags can not be flown in our own territories is unacceptable.”

Brea Corbet, the only trustee with voting power who did not vote to restrict the Pride flag, told an earlier bylaw policies meeting: “When we remove rainbow flags and heritage flags, we are not protecting our Catholic identity; we are revealing institutional fragility. The Pride flag does not threaten Catholic education, policies of exclusion do.”

Three student trustees also opposed the restrictive policy, but their votes unfortunately aren’t counted. We argue this too speaks to the suppression of student voice within the board.

This fragility disproportionately threatens the safety of Indigenous, 2SLGBTQI+ and marginalized students and staff as they are overlooked and dismissed by the flag policy.

Nurturing all students

Kanienʼkehá:ka (Mohawk) education professor Frank Deer speaks of educational programming “that is congruent with the identity of the local community.” This programming, he writes, must go beyond curricula to address the school environment as well. Student safety, inclusion and identity affirmation must be prioritized in all aspects of school life.

Jennifer Brant, a Kanienʼkehà:ka interdisciplinary scholar, speaks in depth about how silence during times like these equates to complicity in accepting injustices that are taking place within “the communities in which we live, the broader society and global communities.”

Inaction in response to this policy is negligent.

Detrimental ramifications may also extend to reconciliation efforts in religious spaces more generally. This regressive policy poses lingering questions about the longevity of Catholic schools if they fail to protect and nurture all students.

Impacts on reconciliation

The primary target of the DPCDSB’s sweeping flag policy is the 2SLGBTQI+ community. In addition, the flag ban attacks Indigenous sovereignty and Anishinaabek nationhood, perpetuating attitudes tied to the Doctrine of Discovery still present in the Catholic ethos.

Flying the flags of First Nations (at their request) is not only a matter of inclusion, it is a matter of respect — respect for the land, the people and the treaties that connect us.

In denying this step towards relationality, this governing body of a Catholic school board sets back the Church’s reconciliation efforts riding on the momentum of the papal visit.

Pope Francis showed in deeds and words he wanted to face the truth in Canada


The board’s ignorance of how this policy risks damaging relationships with students, families and staff at the board, as well as the broader public, partly reflects an indifference that Pope Francis warned Catholics about during his visit:

“I trust and pray that Christians and civil society in this land may grow in the ability to accept and respect the identity and the experience of the Indigenous Peoples. It is my hope that concrete ways can be found to make those peoples better known and esteemed, so that all may learn to walk together.”

Walking together in solidarity

As we write this piece, we can see through the window a local Toronto Catholic Distric School Board elementary school, where an Every Child Matters flag is flown alongside a Pride and Canadian flag.

Catholic education, despite its sordid history and contested perspectives about interpreting and practising Church doctrine, can be a tool to drive reconciliation.

Catholics cannot let a narrow vision overshadow Pope Francis’s pilgrimage and the global Church movement he, the Church’s bishops and Catholic lay people have participated in — via a global synod — to respond to the call to walk together in solidarity with Indigenous, 2SLGBTQI+ and other marginalized people.

Counter-narratives of hope and possibility

We wish to continue to hear counter-narratives of hope and possibility for Catholic education. We wish to see active changes that move the DPCDSB, as scholar Sheila Cote-Meek of the Teme-Augama Anishinabai, writes, “to a drastically different way of being, doing and working.”

As other Catholic boards in Ontario initiate flag debates of their own, we are left with the lingering question. What is the future of Catholic education if it’s not intended to support the physical, emotional, mental and spiritual well-being of all those entrusted to its care?

Why corporations are backing away from supporting Pride this year

Source: The Conversation – Canada – By Leah Hamilton, Professor in the Faculty of Business & Communication Studies, Mount Royal University

Prime Minister Mark Carney recently raised the Pride flag on Parliament Hill and lamented the growing anti-2SLGBTQIA+ sentiment in Canada. He also committed $1.5 million to make Pride festivals across the country safer.

This political support stands in sharp contrast to the many businesses that have reduced or ended their support for the 2SLGBTQIA+ community this Pride season.

Multinational corporations like Google, as well as Canadian-owned companies like Molson Coors, have divested from supporting festivals, while Target has scaled back its Pride merchandise due to threats against employees and large-scale conservative backlash.

The impact is already being felt. Pride Toronto is currently facing a $900,000 funding gap. Executive director Kojo Modeste recently told CBC News this corporate divestment appears to be linked to the larger backlash against diversity, equity and inclusion efforts.

Fear of punitive measures

In January, United States President Donald Trump issued an executive order to dismantle DEI initiatives in federal agencies and target private companies that support DEI measures. In the executive order, Trump’s administration called DEI measures and mandates “immoral discrimination programs.”

Spearheaded by journalist-cum-activist and Trump adviser Christopher Rufo, the attacks against so-called “woke” DEI programs are fuelled by the “culture wars” that pit equity and inclusion against merit and the free market.

Here’s what ‘woke’ means and how to respond to it


Major private corporations, including IBM, quickly bent to the pressure of Trump’s anti-DEI orders by gutting their programs and shifting corporate donorship away from “woke” initiatives.

The pressure to comply with anti-DEI measures hasn’t ended with corporations. More recently, Trump has set his sights on the U.S. post-secondary system, freezing US$2.2 million in federal grants and US$60 million in contracts after Harvard University refused to comply with the administration’s demands related to its DEI programs.

In Canada, the rollback of DEI programs isn’t as loud, but it is happening. Michelle Grocholsky, the CEO of Empowered EDI in Toronto, told CBC News companies are reducing their budgets and cutting their staff. In the midst of job cuts in January 2025, the Alberta Investment Management Corporation removed their DEI staff.

Following in the footsteps of the U.S., Alberta’s United Conservative Party membership passed a resolution to eliminate DEI programs and training in the public service. The party has also indicated it will remove government funding from post-secondary institutions that continue to do DEI work.

Declining public support

In addition to the rollback of DEI programs, the ongoing corporate reductions in Pride support are taking place amid increasing anti-2SLGBTQIA+ sentiment.

A 2024 poll reported that, in Canada, support for 2SLGBTQIA+ visibility — like representation on screens and in sports — is lower than it was in 2021. Compared to previous years, Canadians also expressed less support for transgender rights, and this level of support was lower than the 26 other countries surveyed.

Not surprisingly, this declining public support for the 2SLGBTQIA+ community coincides with rising hate crimes targeting 2SLGBTQIA+ communities. In 2023, Statistics Canada reported a 69 per cent increase in hate crimes targeting sexual orientation.

Public attitudes don’t change in a vacuum. They are deeply influenced by hate movements, political rhetoric and the spread of misinformation and disinformation weaponized by politicians and leaders to dehumanize the 2SLGBTQIA+ community, particularly transgender people.

This dehumanization incites fear, violence and support for anti-2SLGBTQIA+ hate. It has coincided with companies silently withdrawing their support for the 2SLGBTQIA+ community.

Where we live, in Alberta, the provincial government has passed the most draconian anti-trans laws Canada has ever seen. As we (Corinne L. Mason and Leah Hamilton) have previously written, Premier Danielle Smith’s government has unveiled a suite of policies targeting transgender, intersex and gender diverse children and youth in Alberta, and the 2SLGBTQIA+ community more broadly.

In this environment of reduced public and political support, it’s not surprising to see companies backing away from the 2SLGBTQIA+ community.

Getting back to Pride’s roots

The fact that companies have quickly backed away from their support of the 2SLGBTQIA+ community — by halting production of Pride merchandise or reducing sponsorship in Pride festivals — illustrates the conditionality of their support.

Rather than beg big business to come back to the table, some members of the community are using this moment to reflect on how corporate “Love is Love” campaigns haven’t actually led to increased quality of life or justice for our communities.

While it has received less media coverage than calls to remove police from Pride and the presence of Boycott, Divest and Sanction movement at Pride festivals, the corporatization of Pride has long been subject of debate in the 2SLGBTQIA+ community.

Queers and trans say no to police presence at Pride parade


Those against “rainbow capitalism” — the shallow and inauthentic use of Pride imagery in advertising — argue for a return to community-based and radical protest rather than settling for flag-waving bankers throwing beads from atop expensive floats.

Pride Month is rooted in protest and resistance against police violence and systemic oppression. It was led by Black trans women and can be traced back to the Stonewall Riots. Today, Pride still isn’t simply a party and parade.

Authentic ‘rainbow dollars’

In this sociopolitical climate of legislated DEI rollbacks and declining public support for the 2SLGBTQIA+ community, organizations that want to support the 2SLGBTQIA+ community should back up their messaging with meaningful actions and structural support.

Some organizations have shown a commitment to structural support for the 2SLGBTQIA+ community from its beginning, including the Northern Super League, the top-division professional women’s soccer league in Canada. The league openly and consistently amplifies and supports its 2SLGBTQIA+ players, coaches, staff and fans. Founded by Diana Matheson, an openly queer woman, the league is founded on inclusion as a core value.

When it comes to creating Pride merchandise, Social Made Local is a queer-owned Canadian apparel company in Saskatoon that focuses on gender-inclusive sizing, sustainability and community. They donate a portion of their sales to Canadian non-profits like Rainbow Railroad.

Companies that want to show their support can spend their rainbow dollars in good faith through actions that meaningfully support the 2SLGBTQIA+ community. This could include creating programs that support queer entrepreneurs, donating to legal funds that are fighting discriminatory legislation, and partnering with 2SLGBTQIA+ organizations to amplify their work.

Sustainable economic growth in South Africa will come from renewables, not coal: what our model shows

Source: The Conversation – USA – By Andrew Phiri, Associate Professor of Economics, Nelson Mandela University

Coal fired power stations produce 85% of South Africa’s electricity, making the country the biggest producer of harmful greenhouse-gas emissions in Africa. To move away from coal and meet its commitment to reaching net zero emissions by 2050, South Africa needs to dramatically increase production of renewable energy. New research by economics associate professor Andrew Phiri looked at the relationship between renewable and non-renewable energy consumption and GDP growth in South Africa to find out which energy source is most compatible with economic development.

Non-renewables, renewables and economic growth: what’s there to know?

We set out to discover whether renewable energy in South Africa, such as wind or solar power, supports sustainable economic growth. We also wanted to find out if renewables can replace non-renewable energy as a source and enabler of economic growth.

Together with student Tsepiso Sesoai, I did research comparing the impact of renewable and non-renewable energy on economic growth in South Africa.

South Africa currently faces a dual challenge when it comes to energy. It is heavily dependent on non-renewable energy (coal), which also worsens global warming and speeds up climate change. But it desperately needs to grow the economy at a faster rate, given very high unemployment, poverty and inequality.

It’s therefore important to find out whether South Africa would be able to make a smooth transition from non-renewable energy to cleaner energy, and grow the economy at the same time.

Past studies have looked into the role of energy in South Africa’s economic growth, but their methods have provided only limited information about whether South Africa can make a smooth transition from dirty to clean energy.

African economic expansion need not threaten global carbon targets: study points out the path to green growth


To get a deeper understanding, we conducted a modelling exercise. We used an analytical tool called “continuous complex wavelets” to see how renewable and non-renewable energy influences growth over time.

Our model shows that an increased supply and higher consumption of non-renewable energy causes long-term economic growth over 10-15 year cycles. Renewables, at best, have short-term growth effects over six months to one year.

After 2000, there was a very sharp increase of almost 25% in the use of renewable energy throughout the decade. According to our model, this sharp increase was enough to have an impact on economic growth over the short term but not over the long term.

This is because South African energy regulators have not adopted strong enough measures for renewable energy to enable long-term growth. They have not funded the mass rollout of renewable energy, or connected renewables to the national grid. We found that renewables can only sustain growth over six to 12 month cycles whereas policymakers work towards longer cycles such as the 2030 and 2050 sustainable development goals.

Economic growth and coal consumption: what did you find?

In 2003, the government started taking climate change seriously with the release of the White Paper on Renewable Energy. The government started intentionally trying to increase the use of renewable energy while decreasing the use of dirty energy, such as coal. Before this, South Africa’s economic growth was heavily driven by coal consumption.

Renewable energy saw its biggest surge after the 2010 launch of the Renewable Energy Independent Power Producer Procurement Programme. This opened competitive bidding for renewable energy providers to supply electricity to the grid.

The transition to renewable energy had begun. But coal-fired power, while declining, remained the main source of electricity.

In 2019 carbon taxes were formally introduced. This resulted in a further slowdown in consumption of non-renewable energy. The COVID-19 pandemic in 2020 and 2021 coincided with severe power cuts. These two events combined caused a general slowdown in non-renewable and renewable energy use, and in economic growth.

At this point, the drop in coal consumption was actively dragging down the economy. This in turn reduced society’s income, as measured by the gross national product. And because incomes were constrained, fewer private households purchased renewable energy systems. People didn’t spend on solar panels.

What do your findings mean?

Our research suggests that relying on non-renewable energy, like coal, won’t lead to long-term growth for South Africa. This is because non-renewables are not a reliable source of energy, as shown by loadshedding.

Our research further suggests that renewable energy policies, subsidies and programmes made some positive short-term impacts on economic growth, measured as gross domestic product.

Overall, our findings highlight that policymakers have treated renewables as a “nice-to-have” gesture for humanity, instead of a key driver of long-term economic growth.

This has led to weak policies, poor regulation, and under-investment in renewable energy. These have held the sector back from making a bigger contribution to economic growth.

Africa doesn’t have a choice between economic growth and protecting the environment: how they can go hand in hand


For example, the government has not taken renewables seriously enough to include them in the power grid. This has largely limited the use of renewable energy to private homes and businesses. Coal-fired electricity from the country’s power utility, Eskom, is still cheaper for households than leaving the grid and purchasing their own renewable energy infrastructure (solar energy systems). The government has not funded the infrastructure needed to unlock South Africa’s vast renewable energy potential.

The planet is at a critical state with global warming. The government should urgently set up policies and actions to overcome the barriers to using renewable energy. Only then will renewable energy have a permanent, positive influence on economic growth.

South Africa has huge potential in renewables like solar, wind and biomass, thanks to its diverse geography. Yet, when people think about moving away from coal, they worry about job losses in the coal industry. But historically, energy transitions have never been instant. African countries that embraced the change early on reaped the benefits. They became more industrialised and prosperous.

The South African government must act now if it wants to use renewable energy to drive future economic growth and stay ahead in the global shift to clean energy. Climate change affects us deeply. But it also presents a chance for Africa to leap ahead technologically.

Lake Victoria is turning green – the deadly bacteria behind it

Source: The Conversation – USA – By Lauren Hart, PhD candidate, Michigan Geomicrobiology Lab, University of Michigan

Lakes, natural and man-made, provide water, food and habitats for wildlife, as well as supporting local economies. Around the world, though, there’s a growing threat to lakes: toxic bacteria which turn the water green.

This is the same green as you see on stagnant ponds. It’s caused by tiny organisms called cyanobacteria and can be deadly.

Cyanobacteria thrive in warm, sunny lakes and ponds that contain excess nitrogen and phosphorus nutrients derived from fertiliser, manure and sewage. When conditions are right, cyanobacteria multiply rapidly and form smelly green scums on the water’s surface.

Known to science as cyanoHABs (cyanobacterial harmful algal blooms), the scums are harmful to livestock, wildlife, pets, people and aquatic organisms like fish. Toxins make untreated water unsafe to drink, swim in, or even touch. Sometimes they can become suspended in air and be inhaled. The cyanoHABs also harm ecosystems by depleting oxygen, killing off whatever lives in the water, and disrupting food webs and fisheries.

CyanoHABs are a global threat and receive considerable scientific attention in North America and Europe. Blooms are becoming more widespread worldwide because rising temperatures promote cyanobacterial growth and more intense rainfall delivers nutrients from the landscape. Only effective management of nutrients can reverse this trend.

The problem is understudied in Africa’s main lakes, including its largest – Lake Victoria. Past research on cyanoHABs has mostly used microscopy to study the kinds found there, but microscopy cannot differentiate between toxic and non-toxic cyanobacterial cells.

We are on a large project team of scientists who have been studying the socioeconomic and environmental effects of cyanoHABs in the Winam Gulf region of Lake Victoria in south-western Kenya.

Our latest study identified which cyanobacteria were the most abundant in the gulf and which ones were producing the main toxin of concern.

These findings can improve public safety:

  • local authorities can monitor for specific cyanobacteria and warn residents to stay away when blooms are present

  • cyanoHAB prevention practices (nutrient reduction, land-use practices) can target the cyanobacteria that cause the problem.

Greening of lakes

Lake Victoria now receives large influxes of nutrients because of growing lakeside populations and land-use changes. Nutrients from agriculture, industry and urbanisation fuel the growth of cyanoHABs.

CyanoHABs occur in many basins in Lake Victoria but are highly concentrated in Kenya’s shallow Winam/Nyanza Gulf. Changing nutrient and temperature conditions can also alter which types of cyanobacteria dominate the gulf and the types and levels of toxins in the water. Lakeside communities that rely on the gulf for drinking water and domestic tasks are at risk of exposure to cyanoHAB toxins.

Past research on cyanoHABs has mostly used the oldest of microbiological techniques — microscopy — to classify the types of cyanobacteria in the gulf. This cannot differentiate between toxic and non-toxic cyanobacterial cells.

Modern genome sequencing technologies can identify genes encoding the production of known and novel toxins and other molecules of interest, such as those with medicinal properties. Genomic data from African Great Lakes is scarce, so the chemical capabilities of bacteria in this region are largely unexplored. But this is beginning to change.

Our latest study adds to a growing number of recent studies our team has carried out in and around Lake Victoria. In this study, our research vessel stopped at over 31 sites to collect scientific samples and data. The samples were later analysed for DNA, the biological “instruction manual” inside every living thing. DNA tells an organism how to grow, function, reproduce, and – in the case of cyanobacteria – make deadly toxins. This analysis produced near-complete genome sequences – that is, the set of all genes in the DNA – for organisms at each sampling site.

Past reports identified Microcystis as the dominant cyanobacteria in the Winam Gulf. Our research, however, found Dolichospermum was the most abundant type in major cyanoHAB events there. This finding might be due to recent environmental changes in the region.

But we linked Microcystis to microcystin. This is a liver-damaging toxin that can kill livestock, wildlife and humans, especially those whose immune system isn’t working well. In Winam Gulf, it’s often more abundant than the health limits set by the WHO.

Our study also found that Microcystis occurs mainly in murkier river mouths where green scums are not visible, making scientific monitoring and public alerts even more important.

Local authorities can now monitor for these cyanobacteria and warn residents to stay away when blooms are present.

The findings also mean that authorities know which cyanobacteria to target in prevention efforts like reducing the amount of phosphorus and other nutrients entering the gulf.

Lastly, our genomic study uncovered over 300 uncharacterised genes that may produce novel cyanobacterial molecules. These molecules could have toxic or therapeutic effects, and provide an opportunity for future investigators to explore.

A model for what is to come

Rapid human population growth and settlement around lakes and their watersheds is leading to high levels nutrients in lakes around the world. This results in excessive growth of algae and aquatic plants. This danger is likely to increase with global warming because warm temperatures promote algal blooms.

Our data provides a foundation for remedying this in Lake Victoria – and possibly discovering beneficial properties in cyanoHABs.

Has finance for green industry had an impact in Africa? What’s happened in 41 countries over 20 years

Source: The Conversation – USA – By Nara Monkam, Associate Professor of Public Economics, Chair in Municipal Finance within the Department of Economics, and Head of the Public Policy Hub at the University of Pretoria, University of Pretoria

The African continent finds itself in a predicament. Advanced economies in the rest of the world developed through industrialisation: their economies transformed from mainly agricultural to industrial. This involved burning fossil fuels like coal, generating greenhouse gas emissions that caused global warming.

African economies have trailed behind industrially. They’re now industrialising at a time when the world is moving away from fossil fuels and towards solar power, wind energy and hydropower.

Africa has 60% of the world’s best solar resources but only 1% of the world’s installed solar power systems. Despite renewable energy capacity nearly doubling in the last decade, only 2% of global investments in renewable energy went to Africa.

Green industrialisation could be the answer: achieving long-term economic growth and industrial development that does not harm the environment. But in most African countries, renewable energy is more expensive than fossil fuels, which are readily available in many parts of the continent. Africa is also one of the world’s poorest regions and cannot easily afford green technologies.

So a key issue in economic development is how to stimulate green industrial productivity. Green finance (funding from banks and investors specifically for environmentally friendly projects) can fund green innovations. These include renewable energy technologies, energy-efficient building designs, or electric vehicles.

Africa doesn’t have a choice between economic growth and protecting the environment: how they can go hand in hand


I am an economist who worked with a team of researchers to study the impact of green finance on industrialisation in Africa. We also wanted to find out if green innovation influenced the effect that green finance has on industrialisation. (This was measured in this study as the total industrial value added as a percentage of gross domestic product.)

For example, switching to renewable energy like solar power reduces greenhouse gas emissions, and helps mitigate climate change. But the high costs of renewable energy equipment could harm industrial growth.

The research analysed macroeconomic and energy, green finance and industrialisation statistics from 41 African countries between 2000 and 2020.

Our research found that green finance offers funding opportunities for clean and innovative technologies and creating new jobs in green sectors. However, the potential of green financing to drive industrialisation through green innovation (such as renewable energy projects) is not being realised.

How green innovation could be the key to growth for the UK’s rural businesses


This is because renewable energy comes with high costs. There also are not enough skilled people available to run green projects. There’s a lack of proper roads, connectivity or transmission lines to connect renewable energy to the main grid. The basic conditions for industrial growth through renewable energy are not in place.

Governments in Africa should find ways to make green innovation work. This will mean that society can enjoy the benefit of new environmentally friendly projects.

How to make green innovation work

African governments should focus on increasing people’s access to renewable energy projects. For this to happen, they need to put more funding and effort into developing renewable energy infrastructure. Renewable energy technologies must be available and affordable.

Education and capacity building is needed, particularly in rural communities. For example, community-owned solar microgrid projects provide people with the skills needed to manage and look after renewable energy systems.

Governments will need to subsidise local manufacturing of renewable energy components. When these are produced locally, this can help harness the potential of green innovation for industrialisation and also create jobs.

Countries must co-operate regionally on green innovation. This means sharing best practices, pooling resources, and making coordinated efforts towards green industrialisation.

Our research found that it would be useful to set up regional centres of excellence for renewable energy research and development. Regional alliances are also needed, so that countries can work together to negotiate better terms for green finance. This could enhance Africa’s journey towards the kind of green industrialisation that is cost effective and sustainable over time.

What needs to happen next

These steps would boost the impact of green finance on industrialisation in Africa:

  • more climate finance, including finance from the private sector

  • environmental taxation – a policy tool to limit activities, goods or services that have negative environmental impacts

  • reform of multilateral development agencies to make it easier for African countries to access to climate funds

  • development bank funding tailored to the needs of African countries. Nations that invest in renewable energy manufacturing should get tax breaks and other incentives. Green bonds that only fund renewable energy projects should be issued to attract private investors

  • vocational training and higher education programmes that focus on training people in green technologies must get government funding.

Africa has a huge problem with trying to build some resilience to the effects of climate change, such as floods and drought. Economic development is also a challenge on the continent. Both could be addressed by green industrialisation. With the right investments in green finance, innovation and infrastructure, the continent can unlock sustainable growth, reduce poverty and help curb climate change.
