As agroecology gains traction in Australia, many farmers and food systems activists have asked what the differences are between agroecology and regenerative agriculture. So today I’m going to draw from my PhD literature review to try to answer that question. I do so in the spirit of furthering the movement for ecologically and socially just food and agriculture systems, regardless of where any farmer may presently situate themselves along a continuum of agricultural production.
I’m going to take you through what I understand as the history and contemporary state of the rise of alternative agricultures. I’ll then turn to a closer look at regenerative agriculture and agroecology specifically. And I’ll finish with my views on why agroecology offers the transformation our food and agriculture systems need. I do not aim to create divisions in our beautiful fledgling food movement full of hard working and passionate farmers and advocates. On the contrary, I aim to build our collective knowledge, wisdom, and solidarity as we work to radically transform the food system from the ground up. I don’t wish to focus on what regenerative agriculture isn’t, but rather on what it can be, and highlight the dangers of corporate capture to these important parallel movements.
A brief history of alternate agricultures
Farmers and researchers have been practising and writing about the need to move away from chemical agriculture for nearly two centuries – all the way back to George Perkins Marsh’s warnings as early as 1864 in Man and Nature – awork credited with launching the modern conservation movement. Agronomist Sir Albert Howard went to India in the first decade of the twentieth century to ‘teach the locals’ how to modernise their agricultural systems, only to be transformed into an advocate of organic agriculture by what he learned there. Along with Rudolf Steiner J.I. Rodale, and Lady Eve Balfour, Howard is considered one of the founders of the organic movement in the Global North. All promoted the use of composts instead of chemical fertiliser, and focused on the critical roles of humus and mycorrhizal fungi in healthy agroecosystems.
We are in need of a historical corrective here that is as much about today as yesterday. The influence of Indian peasants on the rise of organics in the North is rarely acknowledged. The Green Revolution in India all but decimated small-scale farmers’ traditional, sustainable practices, though the recent farmer protests certainly demonstrate the collective will there to reclaim their right to life and livelihood. While the organics movement has clearly had a net ecological benefit due to reduced use of agricultural and veterinary chemicals (amongst other more sustainable land management practices), what started as a movement has become an industry in its own right. Industrial organics are full of vast monocultures controlled by a decreasing number of corporations. One need only look at the increase in multinational corporations claiming to promote regenerative agriculture to get a taste of what is already happening to this movement (see Walmart, Purina, General Mills, and Danone for just a few, or the consortium that includes Nestlé, Unilever, Kellogg, and McCain Foods for another).
There is an effusive and influential popular agrarian literature on the philosophy and practice of what is considered organic, biological, ecological, regenerative, or agroecological farming. This spans the lyrical musings of bucolic life in the country, exhortations to diversify to maintain the viability of small-scale farms, and socio-political treatises championing the protection of rural communities, local economies, and healthy landscapes.
While it can often seem to be the domain of cis-gendered white men, there are many less celebrated women, BIPOC, and queer agrarian (often explicitly anti-capitalist) thinkers and doers to engage with. One I admire is farmer-activist Elizabeth Henderson of Peacework Farm, a pioneering community-supported agriculture (CSA) farm in the American organics movement. Elizabeth has contributed decades of guidance through columns in The Natural Farmer magazine and community-supported publications on CSA, and also as a leading member of Urgenci: the International Network for Community-Supported Agriculture.
Yet while the emergence of the CSA movement in the United States is largely credited to two white-owned farms in the mid-1980s, it can also be tracked to Black horticulturalist Booker T. Whatley’s ‘clientele membership club’ established in the 1960s, as recorded in his 1987 guide How to Make $100,000 Farming 25 Acres. Both of these CSA origin stories arise from economic and ecological sustainability narratives and constitute quite radical moves to solidarity economies, as small-scale farmers were rapidly disappearing in the ongoing commodification of food production. However, Whatley’s work included an explicit focus on support for Black farmers who suffered from racialized limited access to government support.
Black farmer-activist Leah Penniman of Soul Fire Farm is a more recent inspiration to many. In 2018 she published Farming While Black, a contemporary practical and liberatory guide to everything from land access to composting. Temra Costa’s celebratory anthology Farmer Jane: Women Changing the Way We Eat  profiles 26 women across America farming, cooking, and advocating for change, and Trina Moyles’ Women Who Dig: Farming, Feminism, and the Fight to Feed the World  offers a more radical feminist political lens on the efforts of women across three continents farming against the tide of food system injustices.
In Australia, Bruce Pascoe published Dark Emu in 2014, which argues that there is a long history of Aboriginal agriculture, and his and others’ ongoing work to recuperate Indigenous farming practices has had a significant influence within the food sovereignty movement. Pascoe has challenged us with the question, ‘Black people aren’t going anywhere. White people aren’t going anywhere. So what are we going to do about it?’ My PhD project seeks to contribute to working out what we’re going to do about it in the context of small-scale farmers with exotic livestock holding title and farming on unceded Aboriginal lands. I’ll write more on this in a future post.
The origins of regenerative agriculture
Regenerative agriculture’s practices were developed before the phrase was coined by Robert Rodale, J.I.’s son, in the 1980s in the United States. The early works of André Voisin on ‘rational grazing’ (a strong influence on the creator of Holistic Management Allan Savory) remain deeply influential in the regenerative agriculture movement, and spawned an entire education industry around holistic planned grazing of livestock, particularly cattle.
Regenerative agriculture is described by many as an approach to food and farming systems which aims to recuperate biodiversity, soil, water and nutrient cycles, economies, and communities. It has notably grown in public awareness over the past decade, and especially the last few years in Australia, as the country has suffered unprecedented fires while enduring extended droughts. The literature is extensive and still growing. Some of it focuses on farmers’ experiences and reasons for transitioning away from industrial agriculture, while much concentrates on the importance of soil, or on various techniques, and others on regenerative agriculture as a way to mitigate and adapt to climate change. Charlie Massy’s triumphant 2017 account of a dozen broadacre farmers in Australia who have overcome the ‘mechanical mindset’ to farm with nature is arguably one of the most radical of regen ag’s foundational texts, as it actively tackles questions around farmers’ very ways of thinking and being in the world.
Despite these steps forward, many believe that regenerative agriculture remains insufficient. While it accepts the shared biogeological nature of agricultural landscapes, it remains looped into the premises of economic and sociopolitical systems that treat farms and farmers as separate economic units. The two impulses are incompatible. We cannot return to an agriculture that acknowledges a more natural economy defined by a shared ecosystem that still operates under a social system that defines farmers almost entirely as segregated competitors in the market and sectioned-off on the landscape. Such systems reward practices that externalize the damage of such agriculture off-farm and onto our neighbours, both local and global.
Agroecology as ecology and social system
Let me be clear that regenerative agriculture represents a rightly celebrated step forward. There are also other alternatives that can take us a few more steps forward. And I’m sure all of us want that.
While regenerative agriculture has gained momentum and prominence in Australia, agroecology is much less well-known or understood here, though there is a deep and substantial literature on agroecology internationally. Broadly speaking, agroecology is a scientifically and experientially justified practice of agriculture that is sensitive to the ecosystems in which it is situated and that fosters the democratic participation of farmers in the food system. Its original and still predominant practitioners are Indigenous peoples and peasant smallholders the world over. Many of its advocates make a strong case for relying on peasant and Indigenous knowledge of their land and systems to produce sufficient food sustainably. A science, a set of practices, and a social movement, agroecology is fundamental to my own research project, including its concerns with the importance of biodiversity, the role of animals in agroecosystems, and the lived social, economic, and political realities of small-scale farmers.
The term agroecology was coined by Russian agronomist Basil Bensin in 1930, and the practice emerged as more of a social movement in Mexico in the 1970s in resistance to the Green Revolution. Much research has focused on the diversification of agroecosystems ‘over time and space at the field and landscape level,’ and on enhancing ‘beneficial biological interactions and synergies among the components of agrobiodiversity, thereby promoting key ecological processes and services’. There is also a focus on supporting resource-poor farmers in managing their agroecosystems with minimal inputs.
The democratic and ecological potential of agroecology and its political expression in food sovereignty has been well canvassed for decades. There’s been an explosion of publications in the last decade that coincided with the UN Food and Agriculture Organisation (FAO) launched a process and series of global and regional symposia on agroecology in 2014. Political analysis in agroecology extends from Marxist ecological examinations of racism in food and agriculture systems, to maintaining the integration of Indigenous peoples and peasants within a matrix of wild and managed ecosystems, to rejecting imperialist attempts to lock up ‘nature’ to protect it from ‘humans’. The concept of ‘nature’s matrix,’ in which biodiversity, conservation, food production and food sovereignty are all interconnected goals represents a stark contrast to ‘land-sparing’ arguments that posit humans as separate from and antithetical to the health of functional ecosystems. This debate is currently being played out in the UN’s work on development of the post-2020 Global Biodiversity Framework, with peasants, fisherfolk, and Indigenous peoples defending their rights to customary lands and territories as governments and conservation groups push for further enclosures.
Presently there are economic, political, and cultural lock-ins that limit the ability of Australian farmers to shift to agroecology. At the same time, there are what Alastair Iles proposes are enablers. At its core, Iles asserts:
Geographical and environmental conditions have made – and are making – it hard for farmers to adopt agroecological practices. Strong beliefs among scientist, industry, and government elites in the power of science and technology to overcome climate constraints are leading to agroecology being ignored.
He proposes that some of the implications of neoliberal agriculture policies for agroecology in Australia include:
- Weak farmer resources for adopting agroecological practices;
- demoralized and eroding rural communities; and
- investment in export support instead of environmental support’.
In turn, enabling dynamics for an agroecological transition include:
- coalescing social organization;
- effective agroecological practices;
- external allies; and
- favourable policies.
All of the above enablers are currently coalescing in Australia under:
- a global pandemic;
- strengthening global and national food sovereignty movements;
- the emergence of agroecology schools such as those run by the Australian Food Sovereignty Alliance (AFSA); and
- increasingly supportive state governments offering targeted support for small-scale farmers.
Food sovereignty embodies the collective politicisation of agroecology. It asserts everyone’s right to nutritious and culturally appropriate food produced and distributed in ethical and ecologically sound ways, and our right to democratically determine our own food and agriculture systems. With its political roots established in the mid ‘90s in the fertile soils of La Vía Campesina (LVC) – the global alliance of peasants – food sovereignty was launched into public political discourse at the World Food Summit in Rome in 1996. In the words of McMichael, ‘food sovereignty emerged as the antithesis of the corporate food regime and its (unrealized) claims for “food security” via the free trade rules of the World Trade Organization (WTO)’.
Agroecology fundamentally aims to promote the deep ecological, social, and economic knowledge of First Peoples, peasants, and other small-scale food producers and custodians of land. It puts decision making power back in the hands of Indigenous Peoples and peasants and local communities.
Regenerative agriculture is promoted and practised by many who are thinking and acting in much more holistic ways than industrial agriculturalists, but as a people’s movement, the approach presently lacks coherence and cohesion. Too much of what I see promoted as regenerative agriculture is still just capitalist agriculture with better inputs. Its ecological work is important but ultimately iterative rather than transformational because of its lack of a political framework. In a critical way regen ag is repeating the errors of the organics movement. Organics were commodified and consolidated because the sector lacked a collective vision to unshackle itself from capitalist food systems.
To my knowledge, regenerative agriculture has not developed a theory of change for an economic or social transformation, and is growing a new generation of ‘experts’ and gurus who profit from teaching the ‘how’ rather than the ‘what’ or ‘why’. This is a critical juncture for regen ag – can it shift to teaching the ‘what’ as well as the ‘how’? Who will its teachers be? Will they accept the challenge to think and advocate beyond farm boundaries to the broader social and political economies and ecologies within which farmers care for country?
Agroecology, on the other hand, has a well-developed theory of change. It works to support horizontal knowledge sharing by empowering farmers and their communities to learn from and with each other and the land and all on it, rather than relying on external experts for inputs of knowledge or other resources.
Further, by collectivising and uniting the voices of the people in democratically constituted organisations like the Australian Food Sovereignty Alliance (AFSA), and actualizing shared decision-making, agroecology offers genuine political strength and capacity for policy reform as well as grassroots transformations. A major strength of agroecology is that it is immune to being captured as a brand due to its grassroots, democratic principles and practices – nobody can own or certify agroecology because it asserts everybody’s right to practice it without reliance on or creation of externalities.
My intentions are altruistic. I do not aim to divide us, but rather to help understand our histories and ways forward from here. Our objective should be to offer every kind of farmer a path to the next food landscape forward. Regenerative agriculture and agroecology proponents and practitioners ultimately want food and agriculture systems that are ecologically sound and socially just. If we work together, actualizing everyone’s right to nutritious, delicious, and culturally appropriate food produced and distributed in ethical and ecologically sound ways, Australia can get there.
