A major new declaration co-initiated by York University professor and philosopher Kristin Andrews affirms there is strong scientific evidence that not just mammals and birds, but potentially all vertebrates and many invertebrates, possess conscious experiences.

The New York Declaration on Animal Consciousness, unveiled on April 19 at a conference at New York University, states that the empirical evidence indicates “at least a realistic possibility” of conscious awareness in reptiles, amphibians, fish, cephalopod mollusks like octopuses, decapod crustaceans like crabs and lobsters, and even insects. Andrews co-initiated the declaration along with Jeff Sebo from New York University and Jonathan Birch from the London School of Economics.

“Recent research has shown stunning evidence of consciousness-related behaviours in a wide range of animals,” says Andrews, a professor in the Faculty of Liberal Arts & Professional Studies. “The declaration affirms that we can no longer assume these creatures are insentient or incapable of feeling.”

The declaration – which has already been signed by more than 80 leading scientists and philosophers across disciplines – focuses on the most basic form of consciousness – the subjective experience of being an organism and the ability to feel sensations such as pain, pleasure and hunger. While higher-order consciousness involving self-awareness is not attributed, the statement says it would be “irresponsible to ignore” the possibility that these animals can have positive and negative experiences.

For Andrews, the York Research Chair in Animal Minds who has studied animal cognition for more than 30 years, the evidence from recent studies on seemingly conscious behaviours in creatures including bees, crayfish and wrasse fish is compelling.

“We’ve seen bumblebees exhibiting placid, playful behaviours for no apparent reason other than enjoyment,” she says. “Crayfish show anxious behaviours that change when given anti-anxiety medication. Wrasse fish seem to recognize bodily markings when shown a mirror.”

Such findings challenge the assumption that invertebrates and cold-blooded animals are insentient automata. The declaration argues that when there is a realistic chance an animal has conscious experiences, we are ethically obligated to consider its welfare interests.

“It doesn’t mean we can’t ever eat them or use them,” clarifies Andrews. “But it does mean we need to recognize they likely can feel pain and pleasure, and minimize the negative experiences we impose on them.”

While the declaration doesn’t prescribe policies, Andrews hopes it will prompt wider consideration of how human activities impact invertebrates. She points to the need to include cephalopods and crustaceans under animal welfare regulations in Canada, alongside chickens, pigs and fish.

More profoundly, Andrews sees an opportunity for new scientific insights by studying consciousness across a broader range of organisms. “If even simple animals like worms or flies are conscious in some way, they could provide a revelatory model for understanding the fundamental nature of consciousness, without the confounding factors like language that make human consciousness so complex.”

By expanding our “circle of moral consideration,” as Andrews puts it, the declaration opens perspectives on the richness of subjective experiences pervading the natural world. “It offers the possibility of feeling a wider, deeper connection to all the creatures around us.”

Andrews and her colleagues hope The New York Declaration will be an impetus for more research, greater ethical deliberation and, ultimately, a heightened societal valuation of the experiences of non-human minds.

York U student research reveals importance of native shrubs to wildlife

A research paper by master’s student Ethan Owen, from York University’s Faculty of Science, was recently published in the journal Biodiversity and Conservation. Titled “The importance of native shrubs on the distribution and diversity of reptiles and amphibians in the central drylands of Southwestern USA,” Owen’s first-ever published study involved scouring 43 sites across California’s deserts with his team to understand how the density of native shrubs affects local wildlife.

Armed with high-resolution satellite images and citizen science data sourced from the Global Biodiversity Information Facility (GBIF) – an international, open-access network and data infrastructure funded by the world’s governments – the researchers set out to uncover hidden patterns in these rugged landscapes.

The team’s findings showed that areas with higher shrub density had significantly more abundant, rich, and diverse reptile and amphibian communities, proving the shrubs are indispensable for the creatures’ survival by creating microhabitats that offer cooler temperatures and crucial hiding spots.

“These shrubs are more than just plants; they are lifelines,” explains Owen. “In the central drylands of California, they provide essential shelter, food, and protection for a variety of reptile and amphibian species, helping them survive the extreme conditions.”

But the study didn’t stop at counting reptiles and amphibians. Owen’s team looked at different levels of aridity to see if the relationship held up. “It was fascinating to see that regardless of how dry the area was, the presence of these shrubs consistently boosted the diversity and abundance of the local wildlife,” he says. “It really underscores their importance in these arid ecosystems.”

Owen believes the implications of this research are profound, offering valuable insights for conservationists and land managers alike. “By maintaining and promoting native shrub species, we can support biodiversity, even in the face of climate change,” he says.

As the natural world continues to suffer the consequences of global warming, Owen hopes that research like his will serve as a reminder that even small interventions – like protecting existing shrubs or planting new ones – can have significant positive impacts on the health and diversity of the Earth’s ecosystems.

Lassonde celebrates International Women in Engineering Day

Woman engineer

Each year on June 23International Women in Engineering Day honours the efforts and achievements of women while highlighting the need for diversification in the field. In celebration of this day, York University’s Lassonde School of Engineering is spotlighting Zoi Ralli, Stavroula Pantazopoulou and Baoxin Hu – three of the many inspiring women at Lassonde who are demonstrating excellence in engineering through their passion, expertise and solutions-driven research.

Zoi Ralli

A postdoctoral fellow in the Civil Engineering Department, Ralli has developed and tested a novel, sustainable concrete formulated with recycled waste material instead of cement.

“Cement production is a very energy-intensive process,” explains Ralli, “and it is responsible for seven per cent of carbon dioxide emissions globally.”

Ralli’s cement-free concrete addresses the extreme sustainability concerns of traditional concrete production, boasting a 70 to 90 per cent reduction in carbon dioxide emissions. The material was developed with byproducts from a Canadian quarry, comprised of Earth materials and minerals like silicon and aluminum. She also designed the concrete with microfibers to improve its overall strength and performance. These steel, needle-like fibers allow the concrete to withstand harsh conditions, while minimizing cracking and increasing durability.

Our paper shows that it is possible to completely eliminate the use of cement by replacing it with geological and industrial waste materials to develop a high-performance and sustainable concrete,” she says.

Stavroula Pantazopoulou

Another achievement worth celebrating is the recent recognition of Lassonde Professor Stavroula Pantazopoulou – coincidentally, Ralli’s supervisor – as a fellow of the prestigious Canadian Academy of Engineering (CAE). This distinction reflects her significant research impact and dedication to science and engineering, further underscoring the exceptional contributions of women at Lassonde.

“For me, this award represents the most important recognition of my work,” says Pantazopoulou, who was one of a small number of highly accomplished individuals to be selected as a CAE fellow this year. “No other award compares to this one.”

This commendation is a testament to the transformative efforts Pantazopoulou has made to the field of structural engineering. Her research focuses on addressing a range of complex and emerging infrastructure concerns. In particular, she dedicates her work to enhancing the structural design of various infrastructure, to improve resistance against earthquakes and other extreme events. Though modern infrastructure is typically developed with resilient materials, many older buildings are constructed with less advanced components, posing safety risks to occupants. To address this concern, Pantazopoulou’s work aims to upgrade and retrofit older buildings with new and innovative materials.

As a newly appointed CAE fellow, she is positioned to further advance the field of structural engineering and elevate her research to new heights.

Baoxin Hu

Hu, a professor in the Department of Earth & Space Science & Engineering, is an accomplished researcher at Lassonde who recently secured significant funding – three grants in total – from the Canadian Space Agency and Forestry Futures Trust Ontario. She will use this support to advance her forest management research through remotely sensed data analysis and the development of various artificial intelligence (AI) technologies.

Motivated by the urgent demand for accurate information regarding carbon sequestered forest ecosystems, as well as the need for highly qualified personnel with particular skills and knowledge to help tackle climate change, Hu is leading a multidisciplinary team to address and create solutions for carbon stock in forest ecosystems. Through funding from the Canadian Space Agency, the team will use satellite Earth observation data to develop AI methods that can accurately quantify carbon flux and stocks in Canadian forests.

With funding from Forestry Futures Trust Ontario, Hu’s second project is aimed at improving sustainable forest management and biodiversity conservation by developing AI methods to survey lichens in Canadian forests. These organisms play many critical roles in forest ecosystem dynamics, like serving as a dietary source for various animals and supporting water and nutrient cycling. Using single photon LiDAR (SPL) data, Hu and her team will map and characterize lichens in the Ontario boreal forest and use this information to develop AI methods that can effectively predict lichen distribution in other forest ecosystems.

Hu’s third project, also funded by Forestry Futures Trust Ontario, will explore drone-based AI technologies, referred to as remotely piloted aircraft systems (RPAS), and their ability to analyze conditions of forest ecosystems. Specifically, these RPAS will collect data concerning the effects of silviculture, which is the practice of controlling the growth and composition of forests. By collecting this data, different forest ecosystems can be classified based on the intensity of silviculture, enabling forest managers to gain a more comprehensive understanding of forest environments.

York alumnus helps Ghana farmers flourish

By Elaine Smith

Moustapha Seck, an electrical and electronic engineering graduate from York University’s Lassonde School of Engineering, has created a company in Ghana that provides loans, market access and guidance to small-scale farmers in Ghana.

One of every two adult Ghanaians work as smallholder farmers, and many of them merely subsist, struggling to achieve profitably year after year. Seck created a company called Fluid Finance Technologies after identifying the need for those farmers to be able to obtain loans, despite their lack of collateral, to improve their businesses with more modern equipment and the latest agricultural knowledge, thus creating wealth for them. “There was a lot of education needed and lots of people have taken advantage of them, so their work was often a zero-sum game,” Seck says. “We wanted to turn that into a win-win situation.”  

Moustapha Seck
Moustapha Seck

Fluid Finance Technologies looks to create those scenarios by offering aid to smallholding farmers in Ghana and creating a bridge between them and the banking community so they can obtain business loans. Seck had no contacts in the banking industry as he was starting out, so it required a lot of cold calls and a lot of research and attending conferences to convince people that his company could be trusted. One bank got on board in 2022, and now Fluid Finance works with nine financial institutions in Ghana and about 6,000 farmers.

The company and its success is driven, in part, by Seck’s time at York University.

Seck was born in Canada and split his childhood between Senegal, his parents’ birthplace, and Canada, where his father taught finance at the University of Windsor. As he enrolled at York, Seck had a firm goal. “For me, it was all about studying something that would help me be an asset to the African continent,” he says.

Initially, that ambition took Seck on a different path than where he has ended up today. “In Senegal, there used to be a lot of power outages, so I thought an electrical engineering degree would help me fix that problem,” he says. Seck did pursue opportunities in that direction, like an internship at Hydro One and jobs with a startup venture and a technology company. That is, until an experience with a lender that helped e-commerce businesses get started got the wheels in his brain spinning with ideas.

“I see everything through the lens of creating opportunities in Africa,” he says. He saw value in how he might be able to help business in Africa get off the ground or achieve greater profitability. “So, I transitioned to finance and learned on the job.”

Now four years into existence, Fluid Finance Technologies assists banks with collecting and digitizing the information about farming they need to make decisions about providing loans to individual farmers. The company also brings in agronomy experts to teach farmers about appropriate fertilizers and new harvest methods and how to troubleshoot problems. In addition, Fluid has worked to ensure that farmers have fair and available markets for their crops. 

The result? Banks understand the needs of the local farmers and a willingness to work with them means new banking customers. Meanwhile, farmers get the financial, marketing and agricultural assistance they need to succeed and earn a living wage.

Looking ahead, Seck hopes to expand the business to other African countries in the Global South. He is also thinking about how to provide farmers with markets on a global scale and trying to be proactive about climate change, “giving farmers access to resources ahead of time so they can withstand shocks.”

For Seck, it’s all about advancing a singular passion, one readily found on his LinkedIn page like a motto: “Creating opportunities for people in the Global South is my calling.”

Innovative feature highlights pollinator garden, York U’s sustainability efforts

pink flowers pollinator garden BANNER

By Alexander Huls, deputy editor, YFile

A new augmented reality (AR) experience offered at the pollinator garden at York University looks to engage the community in the greening of campuses and serves as the latest example of York’s broader sustainability efforts and leadership.

York community members who decide to travel to visit the pollinator garden – designated as a haven for birds, bees and butterflies ­– on Chimneystack Road at the University’s Keele Campus will find an innovative surprise among the native plant and wildflower species.

Posted on new signs are QR codes that – when captured with smart phone or tablet – invite a special visitor to their screens: an augmented reality butterfly, eager to land on the user’s palm. The AR experience is meant to reward and delight those who visit the gardens, while fostering an awareness of the vital role pollinators – like butterflies, along with birds and bees – play in the world’s ecosystems.

“Through these gardens, we not only provide essential foraging and nesting sites for pollinators but also create green corridors that promote biodiversity and ecological connectivity,” says Stewart Dankner, director of property management, facilities services at York.

The garden is one of several naturalized spots strategically dispersed across University campuses – ranging from rooftop gardens to designated wildflower patches – that are designed to “green” the landscape and support diverse pollinator species. The pollinator garden has been recently seeded and is expected to grow and thrive over the coming years – in good part because of the creatures that will visit it.

In that way, the AR experience is designed to encourage community members to think about the importance of pollinators. In addition to butterflies, bees are a particular target of these gardens, as they are among nature’s most specialized and efficient insect pollinators – collecting pollen and nectar from flowers to feed themselves and their larvae – that contribute to one in every three bites of food we eat.

Bees are also an area of York leadership and study through experts in the field like Distinguished Research Professor Laurence Packer and the Centre for Bee Ecology, Evolution & Conservation (BEEc), which strives to advance research in the fields of bee ecology, evolution and conservation to increase the long-term sustainability of bees and the vital ecosystem services they provide.

Stewart Danker

The gardens then are reflective of not just BEEc efforts but tied to broader ones around York looking to advance United Nations Sustainable Development Goals centred on contributing to protection, restoration and sustainable use of ecosystems to halt biodiversity loss.

“The collective effort to establish and maintain pollinator habitats aligns with broader sustainability goals, underscoring dedication to environmental stewardship and conservation,” says Dankner.

Those goals and efforts have led to the University being recognized as one of Canada’s Greenest Employers and the recent announcement that it would be aiming to achieve net-zero emissions by 2040 – a decade sooner than its previous commitment.

The seeds for reaching that goal are being nurtured by initiatives like the new AR experience and the pollinator gardens, which students, faculty, staff and others are encouraged to enjoy – whether during a walk, a living lab supporting teaching and research, or more. Further information about the pollinator habitats can be found through the Office of Sustainability website.

Student-led group tackles Indigenous food sovereignty

Learning Spirit Alliance workshop group photo

After personally experiencing food insecurity, and witnessing its effects first-hand, a group of York University Faculty of Health students decided to do something about it.

The Learning Spirit Alliance is an Indigenous student-led group, open to all York students, committed to educating the community about food sovereignty and helping to prevent poverty and food insecurity on campus. Led by current students Leo Manning and Rainingbird Daniels, and former student Shanice Perrot, the initiative was established as a result of discussions with Indigenous students about access to food – particularly healthy and traditional food, and especially for students who had moved away from home.

“Members of our leadership team have personally experienced the effects of food insecurity and lack of food access throughout their time in post-secondary education,” explains Daniels. “There are many Indigenous students facing the increasingly high cost of housing both on and off campus; required meal plans at institutions and/or inflation of food costs; transportation costs associated with travelling home; and a lack of sufficient funding while completing post-secondary education.”

Launched last year with funding from a national organization called Indigenous Youth Roots, the Learning Spirit Alliance held three Food is Medicine workshops this semester, where both Indigenous and non-Indigenous students were welcomed at Skennen’kó:wa Gamig – the gathering space for York’s Indigenous community – and taught how to make traditional Indigenous foods such as elk stew, bannock, three sisters salad and various soups. Each participant was also given an honorarium towards groceries.

According to Daniels, the feedback received from the community has been overwhelmingly positive.

“The different dishes we learned to make gave me the knowledge to make affordable and healthy meals while in residence and away from my traditional territory,” said workshop participant and York student Doreen Scow.

“The workshop helped me feel more culturally involved and connected,” said another participant, student Miigwan Mainville. “This initiative allows us to share stories and laughter with others while sharing cultural food; food is truly medicine.”  

In addition to the workshops, the Alliance held weekly free lunch events for the community, to help bring more traditional and nutritious meals to students in need.

With no plans currently in place for the next academic year, the group’s leadership is using its resources to apply for more grants in hopes that they can continue to host events and workshops on culturally relevant food and food sovereignty, giving Indigenous students the tools they need to cook at home at a low cost.

“We are striving to make a difference in ways that strengthen community and provide relief,” said Manning.

York scholars collaborate on Indigenous-led climate report

York University plays a pivotal role in a groundbreaking report entitled “For Our Future: Indigenous Resilience Report,” which underscores the vital contribution of Indigenous communities in tackling climate change.

The report, a cornerstone of Canada’s National Knowledge Assessment, is co-authored by an almost entirely Indigenous team comprised of Indigenous authors, Elders, wisdom keepers and youth from across the country.

Key figures from York include Professor Deborah McGregor, who is Anishinaabe from Whitefish River First Nation, Birch Island, Ont., and holds the Canada Research Chair in Indigenous Environmental Justice, and former postdoctoral fellow Graeme Reed, now a strategic adviser with the Assembly of First Nations.

“Dr. Reed was lead author, along with Dr. Shari Fox, and coordinated a primarily Indigenous author team for the report,” says McGregor, who has prior experience with climate assessments, notably the “Health of Canadians in a Changing Climate Report,” released in 2022. 

“Natural Resources Canada has coordinated Canada’s climate assessment reports for over a decade. Yet the climate change reports, although important, did not reflect the climate realities and experiences of Indigenous Peoples in Canada,” McGregor continues. 

“To advance the experience, perspectives and realities of Indigenous Peoples in Canada about climate change, it was important to ensure Indigenous Peoples have their voice and conduct their assessment.”

Graeme Reed

Organized according to five key themes, the report highlights Indigenous Peoples’ unique strengths in responding to environmental and climate challenges, positioning them as active agents of resilience and leadership.

Within the research framework, the report underscores the essential role of Indigenous knowledge systems and lived experiences in shaping effective climate action, particularly within the context of food, water and ecosystem interrelationships, and emphasizes the significance of self-determination in Indigenous-led climate initiatives.

At the core of York involvement in the report is the recognition of colonialism’s historical impact, including its role in shaping societal attitudes toward the environment. While acknowledging the multi-faceted nature of climate change and the need to address systemic injustices and historical legacies contributing to environmental degradation, the report also reframes Indigenous Peoples as active agents of resilience and leadership, challenging perceptions of them as passive victims of climate change.

“Drs. McGregor and Reed showcase through this collaborative report their continued national leadership in the discussions of why Indigenous Peoples and our knowledge must be at the forefront of the response to climate change. This continues to demonstrate how Centre for Indigenous Knowledges and Languages (CIKL) researchers are making positive impacts not only at the policy level but also through community-led and driven environmental and climate-based research,” says Sean Hillier, director of the CIKL at York University. 

By amplifying Indigenous voices and perspectives, the report seeks to influence broader climate governance, policy development and decision-making processes, paving the way for meaningful Indigenous climate leadership.

“Climate assessments are intended to influence climate governance, policy development and decisions. We hope that this report influences the broader climate policy landscape to truly reflect the potential of Indigenous climate leadership,” says McGregor.

“Ideally, this report can form the foundation for Indigenous governments, organizations and communities to formulate their own climate policies, strategies and plans.”

Eco Arts Festival to showcase students’ environmental art

A banana fish is set to be one of the hits of the 2024 Eco Arts Festival, an annual explosion of artistic talent organized by the students in the Environmental Arts and Justice (EAJ) program in York University’s Faculty of Environmental & Urban Change (EUC), which marks its 30th anniversary this year.

The Eco Arts Festival is an environmental initiative where art is a catalyst for ecological change and a way to highlight the intersection of art and the environment in the EAJ program. It takes over the lobby and two exhibit spaces – Zig-Zag and Crossroads – in the Health, Nursing & Environmental Studies Building, displaying visual arts and offering performances and readings.  

EUC_The Great Banana Fish migration cover 1

The banana fish, an organically shaped yellow creature, is the star of visual artist and an EUC master’s degree student Michael Bradley’s illustrated book, The Great Banana Fish Migration, a tale that he’ll be reading aloud at the festival later this year.  

This mythical creature fits well with this year’s theme, Beast Friends Forever, a title conceived by festival co-ordinator and EUC doctoral student Giuliana Racco and inspired by Professor Andil Gosine’s research into animal-human interactions and species loss. Gosine is an artist and curator who is the EAJ program co-ordinator. 

“Arts are a place for the students to contend with their anxiety about what is happening in the world, and to think about how we might respond to the crisis we face,” Gosine says. 

Many of the student-artists displaying their work in the festival were enrolled in one or both of Gosine’s two EUC summer courses: Environmental Arts Workshop (for undergraduates) and Cultural Production: Image (for graduate students). These three-week intensive courses are akin to “an arts residency,” says Gosine, who brings artists to class and encourages the students to take their research and passion for environmental issues and translate them in a way that challenges them to explore their creative instincts.  

A similar fourth-year course in the undergraduate EAJ program, Arts in Action, brings together both undergraduate and graduate students to realize the project they have been dreaming up.  

“Fourth-year undergrads and first-year master’s students use the course to deeply explore their interests, with dedicated attention to each of their projects,” Gosine explains. “It’s a rare opportunity to move from research on an environmental concern to exhibition of an artwork that might stimulate conversation and action.”  

As for the undergraduate EAJ program, Gosine considers it unique; he accepted a teaching position at York to be part of it. 

“It’s rare to have such a confluence of learning styles,” he says. “We are allowed to have an interdisciplinary approach. Here, you can be both an artist and a social scientist.”

Chrocheted Chickens

Among the art that festival attendees will see are Tess Thompson-van Dam’s crocheted chicken sculptures harking back to Victorian times when the elites brought chickens to tea parties; drawings by Andrew Carenza that reinterpret horses pictured in historical European paintings through a contemporary, Queer lens; work on historical and contemporary ideas of Eden; and the travelling banana fish. Bradley’s reading of The Great Banana Fish Migration and an Eco Arts collaborative workshop offer participatory opportunities. 

Bradley, an Ottawa Valley native, had a thriving art practice in Taiwan but returned to Canada for master’s studies. He has been drawing banana fish daily since 2018 and creating stories about them. The current book talks about the fish’s journey to find its place in the world and how that might always be changing. 

“I’m not commenting on the politics of migration in a direct way, but when people migrate they have a confused sense of place. I hope people can relate,” he says. “There are a lot of ways that art and environmental science can intersect,” Bradley adds. “I’m not a politician or a policymaker, but artists, creators and curators are part of the cultural community, so if the environment requires a cultural shift, artists are the best people to usher in this change.” 

Bradley’s work, and the Eco Arts Festival, will have that on full display.  

‘We must never give up,’ Jane Goodall tells York community

Jane Goodall at podium BANNER

On April 9, at a special ceremony to award Jane Goodall with an honorary degree, the renowned primatologist and anthropologist shared stories from her life and career with attendees. She also shared why – despite the immense challenges the natural world faces at the expense of climate change – she has hope for the future.

“I still don’t really understand what’s happened to me,” she told the York audience about a career that has led her to become one of the world’s most famous anthropologists and primatologists. Nonetheless, she made an attempt to help those in attendance understand how she became the world-renowned figure she is today from – what she considers – a simple beginning.

“I was born loving animals,” Goodall explained, recounting how as a young child she would climb a tree and watch birds, squirrels, spiders and other creatures. If she couldn’t observe the magic of the natural world directly, she’d read about it indirectly through fantasy-tinged books like Tarzan of the Apes and The Story of Doctor Dolittle. With both novels’ ties to Africa, a seed was planted early for Goodall: she wanted to see the continent herself.

Goodall recounted how many questioned the logic of that newfound desire to travel to Africa and – perhaps – live with the wild animals like Tarzan and write books about them. “Everybody laughed at me,” Goodall said.

Throughout her address, she returned to the importance of the people most important to her journey, and among them was her mother who – even when she was young – never laughed at Goodall’s interest in animals. Once, when Goodall was very young, her mother found she had brought a handful of earthworms to bed. “Jane, you’re looking at them so earnestly, as if you’re monitoring how they’re walking without legs,” she noted. Then, very quietly, she nudged: “We better take them back to the garden.”

Goodall received a similar degree of gentle motherly guidance as she considered pursuing her interest in animals in Africa. “If you really want to do something like this, then you have to work really hard, take advantage of every opportunity, and if you don’t give up, hopefully you’ll find a way,” Goodall recalls her mother saying. “That’s the message I take around the world, particularly to young people, particularly to girls in disadvantaged communities.”

Goodall certainly took that message with her at the time, and did find her way to Africa, becoming a secretary to renowned British paleontologist Louis Leakey in Kenya. As Leakey began seeing Goodall interacting with local animals, he saw something in her. “He apparently decided that I was the person he’d been looking for to be the first to study chimpanzees in the wild,” Goodall said.

So, she did.

For a while, everything that would happen next – the exposure and support she received through National Geographic, the leadership she would demonstrate in guiding science to completely reconsider chimpanzee behaviour and more – would have seemed unlikely to Goodall when she began her immersive study.

The first few weeks were difficult. “For four or five months, the chimps took one look at me and vanished into the forest,” she recalled. She felt like she was making no progress. Goodall’s mother, who had volunteered to come with her to Tanzania, saw it differently, pointing to how in that limited time Goodall had already learned much about the chimpanzees: what they ate, how they communicated and what their communal dynamics were. “She said, ‘You’re learning more than you think,’” Goodall recalls of her mother.

Soon after there also came a turning point in the form of a chimpanzee she would come to call David Gray Beard. “He began to lose his fears [of me] before the others,” she said, which led to her getting close enough to him to observe an – at the time – revolutionary insight: chimpanzees could make and use tools. “That really changed everything,” Goodall said.

In time, Leakey wanted her work to be recognized by the scientific community, elements of which rejected her. Notably, they questioned the empathetic connection Goodall formed with the apes – something she, to this day, is known and beloved for. “’You cannot have empathy with animals and be a good scientist. You have got to be objective. You cannot be objective if you have empathy,’” she recalled being told.

That revolutionary empathy has been a landmark of not just Goodall’s work with apes, but advocacy for the natural world. That was something that especially flourished when she returned to Tanzania to start a research station after her first immersive study among the chimpanzees.

“I got to understand the ecosystem of the forest,” she said. “I see it as like a tapestry. And every time a species disappears from that ecosystem, you pull that thread from a tapestry. And if you pull in other threads, that ecosystem will collapse.”

She began to wonder what would happen if climate change were allowed to run unabated, or if humans don’t do something to control biodiversity loss. She could see first hand the impact poverty has on the environment, “because when people are poor, out in the rural areas, they’re destroying the environment simply to survive.” And the young people she would encounter were similarly concerned with the future. “Young people were losing hope. They were angry,” she said.

Addressing the students in the audience, Goodall admitted the old had have been compromising the future of the young for generations. However, Goodall said there is much that gives her hope. “If we get together, we can start to slow down climate change,” she said. She’s encouraged by many people throughout the world wanting to work to solve the challenges the Earth currently faces. “I’m sure there are students even right here working to try and solve particular problems,” she added.

“There is always hope,” she said. “We must never give up.”

York research advances flood risk management with AI

flood surrounding traffic sign BANNER

In a recently published paper, Rahma Khalid, a PhD candidate in the Civil Engineering Department at York University’s Lassonde School of Engineering, and her supervisor, Associate Professor Usman Khan, proposed a promising new model for flood susceptibility mapping (FSM) that incorporates artificial intelligence (AI) machine learning (ML) methods.

Flood susceptibility mapping – the process of identifying potential flood-prone areas based on their physical characteristics – is a valuable technique used to identify areas that are vulnerable to flooding and inform risk mitigation and protection strategies. Unfortunately, conventional FSM methods rely on time-consuming physical and mathematical models that are also limited in their ability to predict flood risk across large regions.

“We have seen that physical and mathematical models can be very inconvenient for flood susceptibility mapping, especially when it comes to analyzing large areas,” says Khalid. “From a research perspective, we know that using machine learning can improve the speed and efficiency of different processes. This is why we proposed a flood susceptibility mapping model that is leveraged by machine learning for more accurate, rapid and reliable results.”

In their paper, titled “Flood susceptibility mapping using ANNs: a case study in model generalization and accuracy from Ontario, Canada,” Khalid and Khan document how they put their idea to the test and utilized an ML model to map out different regions in southern Ontario and determine their flood susceptibility.

Usman Khan
Usman Khan

They did so by using previously gathered data from different regions across southern Ontario, allowing the model to interpret, identify and predict areas that are at risk of flooding.

The model’s performance was also compared against conventional physical and mathematical models, as well as various emerging ML methods.

“When it comes to flood susceptibility mapping in real-world scenarios, machine learning models have not really been used,” says Khalid. “Industry members are also hesitant to apply these models because there is very little information about their accuracy and reliability.”

Khalid and Khan’s proposed model addressed limitations of other FSM models through training and testing that proved it to be a superior method for flood susceptibility mapping, outperforming other models. It even demonstrated novel capabilities that can help advance the future of flood risk management.

“Our model demonstrated a novel ability to accurately predict flood susceptibility, even across areas that we did not provide training data for,” says Khalid. “Knowing this, we can work towards training our model to understand more about different regions and further improve its ability to predict flood susceptibility in larger areas.”

Currently, Khalid and Khan are working on enhancing the performance of their model with a particular focus on improving data resolution, as well exploring the possibility of supplementing their model with additional ML methods.
