Indigenous agricultural practices, developed over thousands of years, have long been a model of sustainability and resilience. As climate change alters growing conditions across Canada, many Indigenous communities are turning to their traditional food systems and agricultural knowledge to adapt, ensuring food security while maintaining cultural connections to their homeland.
The Importance of Traditional Food Systems
Traditional Indigenous food systems represent complex networks of relationships that connect people, land, culture, and spirit. These systems embody generations of ecological knowledge while sustaining cultural identity and community well-being through sacred connections to ancestral practices.
The cultural and spiritual significance of traditional food systems runs deep within Indigenous communities. Sacred relationships with food sources guide ceremonial harvesting practices and spiritual food preparation protocols. Traditional food-sharing customs strengthen community bonds, while connection to ancestral teachings ensures cultural continuity. These practices align with seasonal celebration cycles, creating rhythms of community life marked by food ceremonies honouring both the sustenance received and the relationships maintained.
Knowledge systems within traditional food practices preserve crucial ecological understanding. Sustainable harvesting methods passed down through generations reflect sophisticated knowledge of species relationships and environmental indicators. Traditional preparation techniques and preservation practices ensure both food security and the maintenance of cultural knowledge. Traditional food knowledge integrates physical and spiritual health, recognizing food’s role in holistic wellness.
Community well-being flourishes through these food systems. Intergenerational knowledge transfer occurs naturally through collective harvesting practices and family teaching opportunities. Community food-sharing networks strengthen social bonds and support traditional economies. These practices build cultural identity while maintaining vital connections between community members of all ages.
Territorial connections remain strong through food practices that maintain relationships with traditional lands. Sacred site protection and traditional territory knowledge guide environmental stewardship practices. Seasonal land use patterns respect wildlife habitat and protect water systems, ensuring biodiversity maintenance for future generations. These connections remind communities of their responsibilities as land stewards.
Physical and spiritual nourishment intertwine within traditional food systems. Beyond providing nutritional well-being, these foods offer spiritual connection and cultural healing. They support mental health through community engagement and physical strength through active harvesting practices. This holistic approach to health recognizes the inseparable nature of physical, spiritual, and emotional well-being.
The contemporary relevance of traditional food systems grows as communities face modern challenges. These systems offer proven strategies for climate change adaptation and food security. Their sustainable practices provide models for environmental protection while supporting cultural revitalization and community resilience. Economic development opportunities emerge through traditional food practices, demonstrating how ancestral knowledge can address current needs.
Climate Impacts on Indigenous Agriculture
Climate change is affecting traditional food systems in various ways across Turtle Island:
- Changing Growing Seasons: Longer, warmer summers in some regions alter planting and harvesting times.
- Unpredictable Weather Patterns: Increased frequency of droughts, floods, and storms threatens crop stability.
- Shifting Species Ranges: Some traditional food plants and animals are moving to new areas or declining in population.
- Water Availability: Changes in precipitation patterns are affecting water resources for agriculture.
Adapting Traditional Practices
In response to these challenges, many Indigenous communities are adapting their agricultural practices, often by blending traditional knowledge with modern techniques.
The Three Sisters: Adapting an Ancient Practice
The Three Sisters agricultural system stands as a living testament to Indigenous agricultural brilliance, representing far more than a planting method. This sacred Haudenosaunee practice demonstrates how traditional food systems create complete cultural economies that define communities’ relationships with their territories while providing sustainable economic foundations.
At its core, the Three Sisters agricultural system reveals sophisticated agricultural knowledge that has evolved over generations. The intricate understanding of how corn, beans, and squash support each other mirrors broader Indigenous principles of reciprocity and balance. This agricultural wisdom encompasses complex soil management practices, traditional climate adaptation strategies, and careful seed selection methods that ensure crop resilience. The system’s ability to maintain ecological balance while providing complete nutrition demonstrates Indigenous peoples’ deep understanding of sustainable food systems.
The cultural and economic significance of the Three Sisters extends throughout community life, supporting traditional trading networks and establishing robust food economies. These practices create pathways for cultural exchange, strengthen economic sovereignty, and maintain systems of social reciprocity. Through these food-based commerce networks, communities build intergenerational wealth while maintaining sustainable livelihoods honouring traditional values.
Sacred agricultural ceremonies and traditional planting protocols root the Three Sisters in spiritual practice, connecting current generations to ancestral teachings. Creation stories guide planting practices, while harvest celebrations mark important community gatherings. These cultural foundations strengthen community cohesion and maintain vital connections to traditional territories and ancestral knowledge.
Innovative Approaches to Traditional Agriculture
Modern applications of the Three Sisters system demonstrate its remarkable adaptability to climate change. Communities select drought-resistant varieties and develop heat-tolerant crops while maintaining traditional knowledge systems. These adaptations enhance biodiversity and build ecosystem resilience, showing how ancient wisdom can address contemporary challenges.
The Three Sisters system powerfully supports food sovereignty, providing communities with food security while maintaining traditional diets and economic independence. This sovereignty extends beyond food to encompass cultural preservation and health independence, demonstrating how traditional agricultural practices support comprehensive community well-being.
The contemporary evolution of the Three Sisters practice shows how traditional systems can adapt while maintaining cultural integrity. Integration of scientific research validates traditional knowledge, while innovative planting techniques address modern challenges. Urban agriculture models and educational programs engage youth, ensuring these practices continue to support community development and economic sustainability.

- Creating systemic support for Indigenous food systems.
The Broader Impact: Lessons for Sustainable Agriculture
The adaptations being made in Indigenous agriculture offer valuable lessons for the broader agricultural, tech and business sectors in Canada and globally.
Research demonstrates that Indigenous agricultural practices, characterized by their emphasis on biodiversity, local adaptation, and sustainability, provide valuable frameworks for climate-resilient agriculture. These traditional approaches offer significant insights for developing world food systems that can withstand environmental challenges.
Rooted in Tradition, Growing Towards the Future
As climate change reshapes the agricultural landscape of Turtle Island, Indigenous communities are demonstrating remarkable resilience and innovation in adapting their traditional food systems. By drawing on ancestral knowledge while embracing new technologies and approaches, these communities are not only ensuring their own food security but also providing a blueprint for sustainable agriculture practices in a changing climate.
As Canada and the world grapple with the challenges of feeding a growing population in an era of climate uncertainty, the adaptive strategies of Indigenous agriculture offer hope and practical solutions. These approaches demonstrate that by respecting traditional knowledge, working in harmony with local ecosystems, and remaining flexible in the face of change, we can create food systems that are not only resilient to climate change but also sustainable and environmentally regenerative.

COP17: Key outcomes agreed at the UN biodiversity conference in Yerevan
Countries have completed the first “global review” of their progress towards reversing nature loss by 2030 at the COP17 biodiversity talks in Yerevan, Armenia.
The review “notes with deep concern” that, unless action is “rapidly accelerated”, the goal to reverse nature loss and meet a set of 23 targets by 2030 “will not be achieved”.
It “urges” countries to accelerate action, including by “increased ambition in addressing the gaps”.
Much of the discussions in Yerevan focused on how to raise the necessary funds to help developing countries protect nature.
Some major economies pushed to expand the range of nations that are expected to provide finance, with countries agreeing at the end of the two weeks of talks that non-donors that want to contribute can “signal interest” before COP18.
This came after developed countries failed to meet a target to significantly ramp up nature finance over the last few years.
It also came as a landmark fund agreed at COP16 in Colombia to pay communities for the genetic resources derived from nature stands nearly empty two years on.
The Yerevan talks marked the halfway point of the “Kunming-Montreal Global Biodiversity Framework” (GBF), the “Paris Agreement for nature” first made in 2022 and due to be achieved by 2030.
During the nearly 12-hour-long final plenary, countries voted for Quito, Ecuador, to host the COP18 nature talks, which will be held in 2028.
Countries managed to sign off on all the major negotiation texts, marking a stark contrast to COP16, which ran so far over time that the Colombian presidency lost “quorum”, forcing talks to resume in Rome months later.
Below, Carbon Brief has detailed analysis of all of the key outcomes from COP17.
Formal negotiations
Finance
Finance, predictably, was at the heart of the discord and deadlock at the Yerevan talks.
At COP17, discussions on finance had to achieve several outcomes.
The first part – to take stock of biodiversity finance mobilised so far to meet the nature deal’s goals – fell under the global review.
As the global report noted, developed countries failed to meet their commitments to raise “at least $20bn a year by 2025” for nature. Delegates pointed to falling aid levels and a sharp 27% decline in environmental funding for the 2026-30 period.
The second part was to agree on how to mobilise resources for the next four years, to meet the GBF’s goals and targets.
Calls to “broaden the contributor base” of who pays to protect nature – and whether that should include emerging economies – became the most fraught element of the talks.
Eventually, countries agreed on what Switzerland described as a “super, mega-delicate” text. It hinged on major “political compromises”, with “no major winner or loser”, according to Kenya.
Per the decision, countries that want to be included on a list of developed country donors can “signal interest” through bilateral, confidential consultations before COP18 and every alternate COP after.
Finally, countries also agreed on criteria to shape and resource a new, permanent financial mechanism to protect nature after 2030.
However, this did not immediately take the form of a new fund under the COP that biodiverse countries have demanded since 2022, deferring the mechanism’s institutional structure to COP18.
Resource mobilisation discussions at the GBF’s halfway mark were supposed to agree on how to close the “biodiversity finance gap” and to “increase resources from all sources” to “at least” $200bn per year by 2030, as set out in target 19 of the GBF.
The talks were largely dominated by a push, led by the JUSCANZ bloc of developed countries, to “broaden the contributor base”. This could see emerging economies, such as Qatar, China, Saudi Arabia and India, being added to the list of countries that pay to protect nature.

Article 20 of the UN Convention on Biological Diversity (CBD) states that developed countries “shall provide new and additional financial resources” to developing countries to meet the costs of implementing measures to protect nature.

The text states that other countries – including emerging economies – may “voluntarily assume” these obligations to pay. However, it adds that this list of developed countries “shall” be reviewed periodically and amended “if necessary”.
The list was last amended in 2006.
(See this “jargon buster” which explains the specific meaning and legal weight of various terms and verbs used in UN formal documents.)
Discussions around this fraught subject had reached a dead end at intersessional talks this year, but resurfaced in Yerevan.
The first “non-paper” had four different options for expanding the contributor base. These ranged from using the World Bank’s country income groups “as a proxy” to identify high-income countries, to commissioning a study on the impacts of being included on the list.
By 21 October, the number of options swelled to eight, including two from Saudi Arabia and one from Peru.
Some countries “expressed concern” that certain options were based on a CBD secretariat study on “what constitutes a developed country”, Earth Negotiations Bulletin reported.
By the end of the first week, it was clear that the finance deadlock would have to go into informal ministerial consultations for any consensus to emerge.
At a press conference on 28 October, Christopher O’Sullivan, Ireland’s nature minister and representing the EU delegation, told Carbon Brief:
“Our position isn’t that we want to pull back in terms of contributing…but it’s been 20 years since that list was added to, times have changed and there are new realities. We just simply want those new realities reflected. I don’t fully understand why there’s so much opposition to that.”
The EU chose not to comment on which countries it would like to see on that list.
Lim Li Ching from the Third World Network, meanwhile, called the push for others to “assume the obligations” of developed countries “sheer hypocrisy”, adding that any country could make a voluntary contribution. She told Carbon Brief:
“At a forum like the CBD, this linking of income status with finance does not take into account where historical and current responsibilities lie. If you want to generate more funding for biodiversity, let’s look at sovereign debt burdens and rules, which are inequitable for developing countries. But if you can fund wars, and provide resources for your defence industry, then you know where the priorities are.”
On 29 October – at a plenary meant to adopt final texts for the most contentious subjects – Norway’s Gaute Hanssen announced that resource-mobilisation discussions would go into a smaller “friends of the chair” meeting.
Facilitated by Carolina Caceres from Canada and Imèn Meliane from Tunisia, the meeting would discuss the most contentious elements of a draft decision that had swelled to 112 brackets, denoting areas of disagreement on specific details in the text.
While the meeting was open to all, countries that were called to be present included Brazil, Canada, Chile, China, the EU, Fiji, Norway, Russia, Switzerland, Saudi Arabia, South Africa and the UK.
At the same time, a “non-paper” text by finance and environment ministers laid out countries’ red lines and compromises.

At the end of COP17, countries welcomed a final compromise text, with Kenya thanking the “strong women” co-chairs who strove to strike a “delicate” balance.
China, Saudi Arabia, Switzerland and Fiji cautioned against any further interventions, with Brazil warning: “If we open this text, we will never close it again.”
While the final decision “recognises” that “contributions from more parties would improve the mobilisation” of biodiversity finance, it steered away from issuing criteria to expand the list of donor countries.
The text makes it clear that no additions to the list would be made without inviting and confidentially consulting with interested countries, to secure their explicit consent.
Instead, the CBD secretariat “invites” countries keen to be on the list and “assume the obligations” of developed countries to “signal interest” before COP18 and at every alternate COP thereafter.
At the same time, developing countries can contribute to meeting the GBF and biodiversity convention’s goals on a “voluntary basis”, with contributions not implying inclusion on the list.
A negotiator for China told Carbon Brief at the closing plenary:
“We welcome this balanced document. It was a very long discussion that has gone [on] since [2022 nature talks in] Nairobi. But actually this time, there were a lot of sensitive issues, [there were] a lot of critical things we didn’t open in the contact groups; it mainly went to the high-level discussion.”
The decision also establishes a financial mechanism for nature funding after 2030 under the governance of the COP, a key ask from developing countries.
However, it defers decisions on what form this mechanism would take – whether this would be a new fund or based o
