Agroecology in Canada: Towards an Integration of Agroecological Practice, Movement, and Science

This article surveys the current state of agroecology in Canada, giving particular attention to agroecological practices, the related social movements, and the achievements of agroecological science. In each of these realms, we find that agroecology emerges as a response to the various social and ecological problems associated with the prevailing industrial model of agricultural production that has long been promoted in the country under settler colonialism. Although the prevalence and prominence of agroecology is growing in Canada, its presence is still small and the support for its development is limited. We provide recommendations to achieve a more meaningful integration of agroecology in Canadian food policy and practice.


Introduction
Contemporary interest in agroecology has emerged in response to evidence of widespread problems associated with the industrial model of agricultural production [1][2][3]. While the industrial model may increase short-term yields of targeted crops in certain geographies and climatic zones, it is also increasingly linked to a number of global environmental problems that compromise the ecological foundations of food systems. These include soil degradation, the depletion and contamination of 'permaculture' and 'biodynamic', are less popular globally than 'organic', all of these approaches are on a trajectory towards, but are not synonymous with, agroecology.
These multi-modal perspectives of agroecology illustrate the different and sometimes competing understandings of "agroecology" as an on-farm practice, "agroecology" as a movement and political tool, and "agroecology" as a science across academic disciplines [2]. This tension, and potential opportunity, sparks a need to address the synergies among different conceptualizations of agroecology among academics, politicians, agricultural producers, and social movement actors. For example, one may ask a direct yet surprisingly complicated question: Why do farmers cultivate biologically complex agroecological systems? Through multiple lenses, responses could include, but are not limited to: (i) To ensure nutrient cycling, yield stability, and ecosystem services [1]; (ii) as an expression of autonomy and bulwark against uncertain and uneven market relations [23,33]; (iii) to carve out alternative agrarian spaces defined by non-commodified exchanges of labour and education [34]; (iv) to counter macro-scale political and economic phenomena and strive for social justice [35]; and/or (v) to improve household and community food security [36][37][38]. Motivations for engaging with agroecological practices are derived from a range of thematic and methodological approaches, including environmental and biological sciences, political economy, labour, food sovereignty, and justice.

The Canadian Context
While the three main identities of agroecology (a practice, a movement, and a science) have received cursory attention from both a global and developing world perspective [2,39], to date, there remain no multi-disciplinary comprehensive assessments that address these trends in a North American context. Canada remains a significant player in global agriculture; it is the fifth largest exporter in the world, including the largest exporter of dominant crops, such as durum wheat, pulses, and oats. According to national databases, the agriculture and agrifood sector employs 2.3 million Canadians. Yet, policies aimed at significantly expanding agroecological production in Canada would run counter to a long history of governmental support for an export-oriented agriculture that is based on economies of scale, mechanization, standardization [40,41], and the widespread and increasingly intense application of industrial style inputs (Table 1). Since the late 1960s, in particular, the federal government has firmly held such a vision for the agricultural sector, with a continued focus on the expansion of international markets and economic competitiveness [42]. Arguably, Canada provides a distinctive context to understand the deployment and constraints of agroecology. Unlike the development of agroecology in many countries as the revitalization of place-based knowledges [43,44], in Canada, agroecology can be framed as a reaction to the environmental degradation caused by a productivist form of agriculture that in fact stretches back to the onset of settler colonialism [45,46]. Indeed, a discursive assessment of agroecology in current Canadian practice, movements, and science generally elucidates a "responsive" agricultural approach to a rather consolidated history of yield maximization models. In this paper, we focus on illustrating the emerging interactions (both positive and antagonistic) among agroecological practice, movements, and science within the Canadian context. We stress that Indigenous food provisioning practices are tremendously important to food sovereignty struggles in Canada [47], and that the advancement of agroecology in this country will therefore need to address the realities of ongoing settler colonialism and Indigenous dispossession [48,49]. This includes an engagement with both the historical trajectories of settler agriculture compromising Indigenous sovereignty [50,51], as well as the current threats to Indigenous foodways due to, for example, development projects, industrial pollution, and treaty violations (where treaties are in place) [52,53]. In this light, it is also important to acknowledge that throughout this paper, we focus exclusively on terrestrial agriculture, as is common in the field of agroecology; however, it must be noted that fisheries, foraging, and other forms of food provisioning practiced by Indigenous peoples are very much aligned with agroecological principles and complementary notions of agricultural bioregionalism [54].
The future of alternative agricultural production in Canada is relevant to not only the security and promotion of sustainable food production at the national level, but also to food production globally. To reflect more on the role of agroecology in the Canadian context, we brought together an interdisciplinary team of scholars and practitioners involved in various dimensions of agroecology. We assess the three themes of agroecology by operationalizing domestic case studies and relate our findings to the opportunities and challenges associated with strengthening agroecology in the context of Canadian policies and practices.

The Scope and Implementation of Agroecological Practices in Canada
There is no commonly held definition of agroecological practice in Canada. The closest proxy is certified organic production, yet, as we note above, organic production fails to capture multiple dimensions of agroecological practices and motivations. However, the number of Canadian farms cultivating organic products increased 65% between 2001 and 2016 (see Figure 1 for data on organic production distribution in Canada), which indicates a trend toward increased ecological farming across the country and possibly a transition to the adoption of more ambitious agroecological practices. Within Canada, organic farming in 2001 was concentrated in Saskatchewan (773 farms), Ontario (405), Quebec (372), and British Columbia (319) [55]. While the Census of Agriculture no longer asks farmers to specify which of their products are certified organic [56], in 2006, the majority of farms reporting certified organic products were producing hay or field crops (2462 farms), followed by fruits, vegetables, or greenhouse products (916 farms) [57]. Despite the growth of organic farming in Canada, certified organic products account for no more than 1.9% of total production. Moreover, the 2006 Census of Agriculture allowed farmers to report selling uncertified organic products, which totaled 11,937 farms [58]. This is indicative of the numerous farms in Canada following organic, ecological, and agroecological practices that remain otherwise unreported. While this question is no longer included in the Census, it is notable that over three times as many farms reported uncertified organic products than those that reported certified organic products. This growth is particularly notable as, simultaneously, the number of farms in Canada continues to decline, having decreased by more than 50,000 between 2001 and 2016. [59][60][61][62]. To characterize what we mean by agroecological, we use examples common in Canada, including the integration of crops and livestock and/or by relying solely on organic inputs. In livestock production, the focus is often on pasture-raised animals and, in the case of cattle and other ruminants, employing rotational (multi-paddock) grazing practices as a form of agroecological practice (e.g., Ecological Farmers Association of Ontario Research Library). In plant-based production, many farms move beyond the Canadian organic standards in terms of disease control and fertility amendments by avoiding even the use of 'natural' pesticides that are listed as 'permitted substances,' and by cycling nutrients on-farm (i.e., preparing their own compost or green manure). Farmers tend to emphasize cover cropping, and agroecological practices that further increase diversity, such as extended crop rotations (e.g., Canadian Organic Growers Gaining Ground Handbook). Though less common in Canada, intercropping and agroforestry are gaining ground as a viable agroecological practice to achieve higher soil fertility and moisture availability. Recently in the province of Saskatchewan, the practice of intercropping was adopted on-farm and recognized as a method leading to decreased synthetic inputs and increased water retention at the farm scale-a practice that thus garnered national attention [63]. Even conventional farmers are indicating a desire to adopt practices that support soil health, such as under the auspice of the Innovative Farmers Association of Ontario. Clearly, however, a systematic survey of agroecological practices in Canada is needed.
Given the dramatic decline of extension services in Canada, and especially those geared toward ecologically oriented production [64], knowledge generation and transfer that supports agroecological practices is largely facilitated by non-profit and grassroots organizations (except for a few examples of government support, such as the Agriculture and Agri-Food Canada Environmental Farm Plan, which encourages ecological and organic agriculture). Examples of these non-governmental organizations and initiatives include USC Canada, The Young Agrarians, The Bauta Family Initiative on Canadian Seed Security (facilitated by USC Canada), Quebec's Coopérative pour l'agriculture de proximité écologique (CAPÉ) and Réseau des joyeux maraîchers écologiques (RJME), and the Ecological Farmers Association of Ontario (EFAO). (These examples do not include national or regional organic networks, such as the Atlantic Canadian Organic Regional Network (ACORN), which engage in knowledge generation/transfer to varying degrees.) For instance, EFAO, a membership-based not-for-profit organization based in Guelph, Ontario founded in 1979 by farmers, for farmers, supports a community of ecological producers through education, farmer-to-farmer training, and knowledge sharing. EFAO is also active in research, with the start of a farmer-led research program in 2016. The program supports EFAO member-farmers to conduct and share the research they conduct for their farms.
These organizations' programming are typically dependent on short-term and unstable financial support, from both government organizations and private foundations. Given the precarious nature of nonprofit funding and the lack of support for agroecological practices in current federal and sub-national frameworks, the innovators and early adopters of agroecological practices are not well supported. Because of these trends, farmer-to-farmer knowledge sharing-a key pillar of agroecology-is happening on the margins of mainstream agricultural training. Except for a few examples of agroecological training (for instance, on-farm training through programs, such as Everdale Environmental Learning Centre, EFAO's field days, workshops and Advisory Services, and the British Columbia-based farmer training schools at the University of British Columbia and Kwantlan), very little support exists to organize and sustain efforts in rural agroecological practice, with minimal agroecology policy to encourage such efforts.
The topic of labour is also significant in terms of the potential for agroecological practices to proliferate in Canada. Historically, women and children have provided unpaid labour to Canadian farm operations, but increasingly young women and men are coming from off farms to work on farms in exchange for an education in ecological production methods [65]. Domestic and migrant farm workers represent the final source of labour on many farms, including relatively agroecological operations. Among larger organic farms, it has been especially common for operators to employ migrant workers through the Seasonal Agricultural Worker Program (SAWP), a program that has been in existence since 1966 and that is designed to have workers from Mexico and several Caribbean nations fill labour shortages on various types of agricultural operations [66,67]. Many producers, including some employing migrant workers, are concerned about the precarity of migrant workers and the lack of citizenship rights they are afforded [68,69]. In the best cases, producers employing migrant workers on agroecological operations through guest worker programs have emerged as strong advocates for migrant workers' rights, calling for paths to citizenship.
Even though state-led support for agroecological practices is minimal, agroecology is gaining traction in several new arenas, including among urban growers [70]. Despite the relatively short growing season, agricultural production is widespread in Canadian cities. A 2002 poll found that 44% of households in Vancouver and 40% of those in Toronto had at least one member who grows food [71]. One might imagine that this involvement has increased with the growing public interest in food over the past decade, and there is reason to believe that many of these growers are partial to practices in line with agroecology.
Recent research has highlighted the viability of agroecology in urban and peri-urban contexts and its potential to advance environmental objectives [72,73] and promote food justice [74,75]. To date, no studies have explicitly researched agroecology in Canadian cities. Yet, community gardening in Toronto and Montreal has been credited with advancing a number of social and environmental objectives, including improving marginalized city dwellers' access to nutritious and culturally appropriate food, fostering community solidarity and development, and promoting democratic practices and activism among previously excluded populations [76,77]. In Toronto, the Toronto Urban Growers (TUG), a network of urban agriculture advocates and practitioners, released a set of indicators by which to assess the effectiveness of urban agriculture projects. Among the 30 indicators identified, seven addressed environmental concerns, including planting practices that lead to improved soil, water, and air quality; storm-water management and water conservation; and increased biodiversity. Another seven indicators focus upon social objectives, such as equality and the inclusion of marginalized populations, social cohesion, and collaboration with other social organizations [78].
Urban growers' interest in environmentally sustainable and socially just food is also mirrored in consumer demand. This is demonstrated in the dramatic growth of Community Supported Agriculture (CSA) initiatives and with the rising popularity and activity at farmers' markets over recent decades [79]. In three case studies of farmers' markets in Ontario, it was found that the most common reasons for attending were the freshness and quality of the food, supporting local farmers, environmental concerns, and sociocultural interaction [79][80][81]. Although some research has found that consumers rarely discuss production systems with producers [80,81], these urban consumers increasingly express an interest in purchasing ecologically produced goods [79].
Initiatives in urban environments, such as the Toronto's Black Creek Community Farm and The Stop; Thunder Bay's Roots to Harvest's urban farm, garden, and edible food forest; Vancouver's Inner City Farms; and Montreal's Lufa Farms, all recognize the mounting consumer interest in purchasing foods grown agroecologically and locally grown by farmers with whom they can interact (see [82]). This phenomenon suggests that the expansion of agroecology in Canada is not only contingent upon 'production practices', but also the social relations of exchange. The implementation of agroecology must consider the entire food system, including consumption and consumer integration, and the broader political and economic systems in which food provisioning occurs [83][84][85]. As we discuss in the following section, an emerging food movement in Canada aims to do just that.

Agroecology and Canadian Food Movements
Agroecological principles have been adopted by food movements around the world in recent decades, with many proponents linking agroecology to struggles for food sovereignty [21,35,86]. Food sovereignty can be described as "the right of all people to healthy, culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own agricultural systems" [87]. The food sovereignty movement's origins can be traced, in part, to the work of the transnational peasant movement, La Vía Campesina, and its efforts in the early 1990s to help marginalized agricultural producers across the globe to resist the industrial food system by placing control of food production, distribution, and consumption within local communities [88,89]. Food sovereignty advocates for the fight for keeping food production under the control of peasants and small-scale sustainable fisherfolk and farmers through the construction of agroecological alternatives that meet their needs [90].
The discursive entry of agroecology to Canada's food movement came via the food sovereignty movement. At local, regional, and national levels, organizations of food producers have embraced the ideals of agroecology, if not necessarily the term. Their combined efforts are working to coalesce Canada's agroecological food producers and their allies into a veritable social movement. At the national level, some of these organizations include the National Farmers Union, Food Secure Canada, USC Canada, and Inter Pares, while Union Paysanne is promoting agroecology in Quebec (especially by way of the 'Centre Paysan', Canada's only peasant-led and La Vía Campesina-recognized agroecology school). Most of these organizations have developed partnerships across the globe, including close ties with other food sovereignty proponents.
Complementing these national initiatives, there are also many regional organizations and individual farms within Canada that have adopted agroecology as part of a food sovereignty approach. For example, in Atlantic Canada, one of the primary organizations working to promote sustainable agricultural systems is the Atlantic Canadian Organic Regional Network (ACORN). Founded in 2000, ACORN is a membership-based non-profit that focuses specifically on supporting the certified organic sector. It provides networking services and engages in education and promotional work. ACORN is also heavily involved in fostering seed security-one of the cornerstones of agroecology-and collaborates with the nation-wide Bauta Family Initiative on Canadian Seed Security to deliver its programming in the Atlantic provinces. This work includes partnering with the Dalhousie University Faculty of Agriculture and Seeds of Diversity Canada to run a regional seed bank. The organization also runs an annual conference and trade show that brings together ecologically minded producers and consumers from across the region.
Though more prominent in an international context, urban food movements that embrace agroecology as a base principle are starting to take hold in Canadian cities. Several urban agriculture initiatives in Toronto engage with newcomer and Indigenous communities to put their agricultural knowledge to work in fostering ecologically sound growing practices. Similarly, Ottawa's Just Food, while initially a grassroots non-profit addressing urban hunger, today supports an urban farm that specifically incorporates agroecological practices. Urban residents and groups, especially urban growers utilizing agroecological science, increasingly fight for their right to shape food production, distribution, and consumption in their communities [91]. Accordingly, in these urban areas, agroecological concepts can also be found in other movements around food justice, community food security, and slow food (see [28,92]).
At the same time, there are also risks associated with the popularization of agroecological practices and discourses. La Vía Campesina and their allies are particularly alert to the possibility of the term 'agroecology' being equated with large-scale monocultural approaches to growing organic food, or with trends, such as 'climate-smart agriculture' and 'sustainable intensification' [93]. This notion that agroecology is at risk of being co-opted has in fact been raised by others in recent years (see [94]). To counter the potential of co-optation, groups have even begun to specify that they are advocating for an explicitly political 'peasant' agroecology that challenges unequal power relations in the food system [93,94]; and, significantly, social movements adopting agroecology have used it as a frame to articulate resistance against the dominant capitalist logic [95].

The Science of Agroecology and the Canadian Scientific Research Agenda
In general, prevailing themes of contemporary agricultural science focus on maximizing short-term agricultural production and profit, while also exploring how crop production can be more socially and environmentally sustainable [1]. By extension, this dichotomy has come to frame academic debates surrounding agricultural research as a series of trade-offs in policy and practice: Organic vs. conventional forms of production [96], intensification vs. extensification [97], and provisioning of multiple ecosystem services vs. yield maximization [98]. As a scientific discipline, agroecology is central in such debates, being widely viewed as a branch of agricultural sciences and ecology that addresses the central question: Can the diversification of agricultural systems enhance the provisioning of multiple beneficial agroecosystem functions, including food production, while simultaneously mitigating the negative environmental and social externalities associated with the industrial model of intensified agriculture [1,[99][100][101]?
Underpinning the majority of agroecological research is a general hypothesis of a positive relationship between biodiversity in agricultural systems and the rate of ecosystem service provisioning [99]. Indeed, this expectation forms the basis of essentially all agroecological research that either explores the ecological, environmental, and socio-economic benefits associated with increasing diversity in agricultural systems, or highlights the negative consequences of reduced biodiversity at the level of the farm through to global scales. Agroecological research tends to evaluate hypothesized enhancements in agroecosystem function between biologically diverse systems and monoculture, and observed differences are then often explained based on long-standing ecological principles, such as niche partitioning, facilitation, and competition [107,108]. In Canada, contemporary themes for agroecological scientific research fall, arguably, into two categories: (i) Studies on productivity, and productivity comparisons between agroecological and conventional systems (e.g., [109]); and (ii) studies on the environmental services (and disservices) conferred by the adoption of agroecological practices (e.g., [110]).
Other threads of agroecological research have tied the ecological basis of agroecology to rural sociology and agrarian studies [111], as well as political ecology [112]. Much of this work examines how agroecology can engage and transform inequitable power and epistemological dynamics in the current agrifood system. This effort to become more transdisciplinary (i.e., crossing academic disciplines, but also knowledge systems) can be seen as a strength by some, and a weakness by others [27], but it is a crucial component in an attempt to coalesce the science, movement, and practice dimensions of agroecology.
In general terms, governments are more inclined to fund research on conventional agricultural practices than on interdisciplinary agroecology and diversified farming. Research shows that in the United States, only~10% of the Department of Agriculture's 2014 budget for "Research, Extension, and Economics" was directed toward research projects focusing on sustainable agriculture, a very conservative estimate for agroecology in terms of representing ambitious and/or transformative agroecological practices [113]. Similarly, in the UK, research has found that UK aid funding for agroecological projects is less than 5% of all agricultural aid funding [114].
To date, no such numbers have been published for Canadian research institutions. While a comprehensive analysis, such as that of [113], is beyond the scope of this paper, the awards database of the Natural Sciences and Engineering Research Council of Canada (NSERC) provides some insights into how agroecology factors into Canadian research priorities. The NSERC Discovery Program represents, arguably, Canada's premiere long-term (i.e., five-year) research funding program. In 2016-17, 9725 projects were awarded in total, with 443 grants awarded under this program that include "agri*" in the title or keywords, totaling some CAD $15.6 million in funding or about 4.75% of the total NSERC Discovery funding for that granting period. Of these, only ten funded projects, totaling CAD $343,500, focus on linkages between biodiversity, agroecosystem management, and agroecological functioning. There are certainly other funded research programs with clear applications for agroecological sciences and management, such as research into crop improvement or remote sensing of agricultural systems. However, explicit research on intercropping, or any other interpretations of agroecological science common in the literature [37], do not factor prominently in the current Canadian science funding landscape.
In Canada, social science research is supported by the Social Sciences and Humanities Research Council (SSHRC), including through the Insight Grants and Insight Development Grants, which support long-term (two to five year) research projects. Data from the SSHRC funding database suggests that, as compared to 2008-09, monetary allocation to agroecological research has nearly doubled over the past 10 years. Specifically, in 2008-09 research projects containing the search terms "agr*" and/or "food" were allocated CAD $994,883 or~1.3% of the total amount disbursed by these SSHRC programs. In comparison, 2.2% of the total monetary awards from these same programs, totaling CAD $2.1 million, were allocated to agroecology-related research programs in 2016-17. This limited financial support may be reflective of the small, albeit growing, presence of agroecology on Canadian farms.

The State of Canadian Policy on Agroecology
Agroecology remains on the fringes of Canadian policy at the government level. While scientific researchers working with Agriculture and Agri-Food Canada (AAFC) have called for a greater exploration of agroecology in Canadian production systems [115], current policy frameworks do not use the term, agroecology, explicitly. As such, existing policies may support climate change mitigation, conservation, or organic production, but they fail to cover the full scope of agroecology's multiple dimensions. For example, federal policy frameworks, such as Growing Forward 2, have highlighted some prioritization of industry-supported research and development aligned with organic practices through the Organic Science Clusters. At the provincial level, voluntary initiatives, such as the Species at Risk Farm Incentive Program and the Species at Risk Partnerships on Agricultural Land Program in Ontario, offer cost-sharing opportunities for farmers to engage in sustainable agricultural production and conservation practices. Additionally, Quebec uniquely offers marginal financial support (up to CAD $20,000) for farmers to transition to organic production [116]. Yet, these government initiatives do not explicitly address agroecology. For instance, through its Next Agricultural Policy Framework, the AAFC has prioritized the mitigation of greenhouse gas emissions and "innovative approaches to address agri-environmental issues" at provincial, territorial, and regional scales [42], providing a potential avenue to integrate agroecological principles into policy.
There are critical challenges to the widespread adoption of agroecology policies in Canada. First and foremost, among these challenges is the state's attachment to modernist values and its perpetuation of settler colonial practices. Since the late 1960s, in particular, the federal government has firmly held a yield-maximization, productivist, and export-oriented vision for the agricultural sector. The current Canadian Agricultural Policy Framework continues to focus on the expansion of international markets and economic competitiveness [42]. Beyond the pressures towards industrialized export-driven agriculture, other influential aspects of Canada's current agricultural policy scenarios can dissuade agroecological production. As an important example, supply management-which aims to protect farm revenues by coordinating the production of dairy, eggs, chickens, and turkeys through the assignment of limited quotas for each sector-features specific policies that may favour large producers at the expense of new and relatively small farmers [117,118]. Over the years, the quota system has made it nearly impossible for new entrants to be able to afford the start-up costs associated with launching a business in these sectors. Additionally, this system makes the integration of crops and livestock a major challenge for growers. High minimum thresholds required to hold quota result in the need for large investment in a single sector, while low exemption thresholds for farmers to engage in these sectors without holding quota make it unlikely for diverse farm operations to be profitable. However, Ontario's Artisanal Chicken Program is a notable exception. By allowing small-scale producers to enter niche markets, it offers a useful example of how to include diversified and smaller-acreage farmers in a supply management system that is generally biased towards heavily capitalized farms [118,119]. Thus, while supply management may ultimately align with the goals of Canada's food sovereignty proponents, substantial policy reforms would be needed for it to contribute to an agroecological food production system.
Beyond state-led processes, there have been a number of efforts to engage farmers and other food systems advocates in policy-making as part of civil society engagement initiatives. Building on the work of [120] in the late 1970s that mobilized a diverse range of actors to critically reflect on corporate power in the food system, the People's Food Policy (PFP) project more recently aimed to establish a pan-Canadian food policy proposal rooted in food sovereignty principles [121]. Launched in 2008, the PFP engaged over 3500 Canadians and Indigenous people in conversations about ways to transform the dominant food system. The project led to the release of a cumulative report, Resetting the Table: A People's Food Policy for Canada [122], which highlighted the top policy priorities and a broader vision for a radically transformed, and substantially more democratic, food system. Although it only mentioned agroecology by name in passing, the PFP explicitly called for integrated ecological systems that include diverse forms of learning and practice (e.g., science and technology, and Indigenous and farmer knowledge); open, democratic, and transparent governance processes; and a connecting of place-based experiences to the growing global food sovereignty movement. These are well aligned with agroecology's key principles [2]. Adopted by Food Secure Canada (FSC), the PFP gained widespread international interest, and its processes of citizen-based policy engagement were adopted by a number of movements in other places (e.g., Australia in 2013 and the United Kingdom in 2017).
In May 2017, when the Minister of Agriculture and Agri-Food Canada launched consultations to inform a national food policy for Canada, FSC coordinated a diverse group of social, ecological, and economic advocates, who brought their voices together on a number of key issues fundamental for future food systems. The hope was that the national food policy for Canada could finally address the fractured, isolated, and often contradictory policies that structure the country's dominant food system. This included a critique that the federal government's proposed framework ignored the view that food production was part of an interconnected and interdependent web of human and ecological processes, as the framework instead focused on conservation (wherein nature is often perceived as distinct from agricultural production), increased production, and food affordability. Working with a range of individuals, organizations, and networks across Canada's food movements, FSC compiled a set of key recommendations rooted in an integrated food systems perspective, reconciliation with Indigenous peoples, the right to food, and adaptive and socially innovative solutions that would combine technology, science, and community-based knowledge. The FSC (2017) report [123] states that, "Over the long term, we should strive towards a process that will lead to the application of the principles of food sovereignty, which has, at its heart, reclaiming public decision-making power in the food system." Much of this work has built on social movements' efforts to make agroecology and food sovereignty a core part of both short-term tactical and campaign-based efforts, and a longer-term strategic vision.

Conclusions
In this paper, we present, from the perspective of the Canadian context, (i) the current practices of agroecology and other non-industrialized forms of agriculture on farms, (ii) social movements connected to agroecology, (iii) the science of agroecology and its role in research agendas, and, finally, (iv) the policy landscape (or the lack of it) on agroecology. We illustrate that agroecology in Canada is emerging in a number of dimensions and that efforts to expand and formalize it have been largely led by non-state actors and initiatives. However, these efforts are frequently disjointed, are commonly precarious and underfunded, and are paired with minimal, or often restrictive, government policy. Furthermore, Canada is not unique in that agroecology has the potential to be co-opted as exclusively a set of technologies for production, such as the federal industry aligned Growing Forward 2 framework, rather than being taken up as a form of resistance against the dominant food production system that is environmentally destructive and exacerbates socio-economic inequalities.
Unlike other contexts, wherein the recent growth of agroecology can be understood as a resurgence of place-based knowledges, particularly given its historical de-development and exclusion from dominant models of agricultural production and land use practices, agroecology in Canada is distinctive as a direct response to the degradation caused by a productivist approach that stretches back to the earliest forms of settler colonial agriculture [45,48]. In Canada, the full-scale industrial model was deployed in full effect following the Second World War, and emerging agroecological efforts are responses to this particular prevailing production; however, the science, practice, and movement associated with agroecology will need to be informed by Indigenous food sovereignty. In Canada, agroecology offers a mode of production that can enhance yield stability, create autonomy against uncertain and uneven market relations, carve out alternative agrarian spaces to counter macro-scale political and economic phenomena, and improve household and community food security. Specifically, developing agroecology in the Canadian context should aim to re-write agricultural science and technology with due regard to traditional Indigenous knowledge systems; the creation of alternative agricultural practices should take place alongside sustainable food provisioning practices that include fishing, gathering, and hunting; and, finally, the movement for agroecology will need to address key issues, such as land access and food distribution, while simultaneously seeking to rectify the relevant injustices that continue to be perpetuated against Indigenous peoples.
As we have highlighted, there is generally a broad enthusiasm for agroecology among Canadian agricultural producers, farmers' organizations, and other food system actors. Yet, in this context, a concerted effort is needed to merge Canada's disparate agroecological practices, movements, and science, as has recently been noted in Europe [124]. For agroecology to achieve the political, environmental, and socioeconomic transformations envisioned by its various promoters, alliances between farmers and non-farmers and between urban and rural stakeholders, and food justice organizations will be necessary in terms of generating popular pressure to change policies and approaches to food system governance in Canada. A movement for agroecology will need to support existing prefigurative approaches to agricultural production, while pushing for these to be replicated and scaled out-an effort that will undoubtedly entail confronting the political economic realities of a system that currently perpetuates labour injustices, corporate consolidation, land speculation, and market-based models that preclude poor people from accessing sustainably produced food.
Funding and support for farmer-led research is also essential. More comprehensive farmer-research collaborations will be necessary, along with increased recognition of existing practices, knowledge, and farmer-to-farmer networks. Similarly, the scientific community will greatly benefit from funding for research on the agroecology of fisheries, and for an agroecology that is informed by Indigenous food systems. Canadian agricultural policy is seemingly shortsighted, particularly in comparison to other countries that are actively integrating agroecology into regulatory frameworks (e.g., Brazil, Cuba, France, Sweden). While we recognize that the transformative potential of policy alone is limited, agroecology is unlikely to become a fundamental tenet of agriculture in Canada unless policies more effectively integrate practices, movements, and science.
