Farming for a Small Planet

People yearn for alternatives to industrial agriculture, but they are worried. They see large-scale operations relying on corporate-supplied chemical inputs as the only high-productivity farming model. Another approach might be kinder to the environment and less risky for consumers, but, they assume, it would not be up to the task of providing all the food needed by our still-growing global population.

Contrary to such assumptions, there is ample evidence that an alternative approach--organic agriculture, or more broadly "agroecology"--is actually the only way to ensure that all people have access to sufficient, healthful food. Inefficiency and ecological destruction are built into the industrial model. But, beyond that, our ability to meet the world's needs is only partially determined by what quantities are produced in fields, pastures, and waterways. Wider societal rules and norms ultimately shape whether any given quantity of food produced is actually used to meet humanity's needs. In many ways, how we grow food determines who can eat and who cannot--no matter how much we produce. Solving our multiple food crises thus requires a systems approach in which citizens around the world remake our understanding and practice of democracy.

Today, the world produces--mostly from low-input, smallholder farms--more than enough food: 2,900 calories per person per day. Per capita food availability has continued to expand despite ongoing population growth. This ample supply of food, moreover, comprises only what is left over after about half of all grain is either fed to livestock or used for industrial purposes, such as agrofuels.[1]

Despite this abundance, 800 million people worldwide suffer from long-term caloric deficiencies. One in four children under five is deemed stunted--a condition, often bringing lifelong health challenges, that results from poor nutrition and an inability to absorb nutrients. Two billion people are deficient in at least one nutrient essential for health, with iron deficiency alone implicated in one in five maternal deaths.[2]

The total supply of food alone actually says little about whether the world's people are able to meet their nutritional needs. We need to ask why the industrial model leaves so many behind, and then determine what questions we should be asking to lead us toward solutions to the global food crisis.

Vast, Hidden Inefficiencies

The industrial model of agriculture--defined here by its capital intensity and dependence on purchased inputs of seeds, fertilizer, and pesticides--creates multiple unappreciated sources of inefficiency. Economic forces are a major contributor here: the industrial model operates within what are commonly called "free market economies," in which enterprise is driven by one central goal, namely, securing the highest immediate return to existing wealth. This leads inevitably to a greater concentration of wealth and, in turn, to greater concentration of the capacity to control market demand within the food system.

Moreover, economically and geographically concentrated production, requiring lengthy supply chains and involving the corporate culling of cosmetically blemished foods, leads to massive outright waste: more than 40 percent of food grown for human consumption in the United States never makes it into the mouths of its population.[3]

The underlying reason industrial agriculture cannot meet humanity's food needs is that its system logic is one of disassociated parts, not interacting elements. It is thus unable to register its own self-destructive impacts on nature's regenerative processes. Industrial agriculture, therefore, is a dead end.

Consider the current use of water in agriculture. About 40 percent of the world's food depends on irrigation, which draws largely from stores of underground water, called aquifers, which make up 30 percent of the world's freshwater. Unfortunately, groundwater is being rapidly depleted worldwide. In the United States, the Ogallala Aquifer--one of the world's largest underground bodies of water--spans eight states in the High Plains and supplies almost one third of the groundwater used for irrigation in the entire country. Scientists warn that within the next thirty years, over one-third of the southern High Plains region will be unable to support irrigation. If today's trends continue, about 70 percent of the Ogallala groundwater in the state of Kansas could be depleted by the year 2060.[4]

Industrial agriculture also depends on massive phosphorus fertilizer application--another dead end on the horizon. Almost 75 percent of the world's reserve of phosphate rock, mined to supply industrial agriculture, is in an area of northern Africa centered in Morocco and Western Sahara. Since the mid-twentieth century, humanity has extracted this "fossil" resource, processed it using climate-harming fossil fuels, spread four times more of it on the soil than occurs naturally, and then failed to recycle the excess. Much of this phosphate escapes from farm fields, ending up in ocean sediment where it remains unavailable to humans. Within this century, the industrial trajectory will lead to "peak phosphorus"--the point at which extraction costs are so high, and prices out of reach for so many farmers, that global phosphorus production begins to decline.[5]

Beyond depletion of specific nutrients, the loss of soil itself is another looming crisis for agriculture. Worldwide, soil is eroding at a rate ten to forty times faster than it is being formed. To put this in visual terms, each year, enough soil is washed and blown from fields globally to fill roughly four pickup trucks for every human being on earth.[6]

The industrial model of farming is not a viable path to meeting humanity's food needs for yet another reason: it contributes nearly 20 percent of all anthropogenic greenhouse gas emissions, even more than the transportation sector. The most significant emissions from agriculture are carbon dioxide, methane, and nitrous oxide. Carbon dioxide is released in deforestation and subsequent burning, mostly in order to grow feed, as well as from decaying plants. Methane is released by ruminant livestock, mainly via their flatulence and belching, as well as by manure and in rice paddy cultivation. Nitrous oxide is released largely by manure and manufactured fertilizers. Although carbon dioxide receives most of the attention, methane and nitrous oxide are also serious. Over a hundred-year period, methane is, molecule for molecule, 34 times more potent as a heat-trapping gas, and nitrous oxide about 300 times, than carbon dioxide.[7]

Our food system also increasingly involves transportation, processing, packaging, refrigeration, storage, wholesale and retail operations, and waste management--all of which emit greenhouses gases. Accounting for these impacts, the total food system's contribution to global greenhouse gas emissions, from land to landfill, could be as high as 29 percent. Most startlingly, emissions from food and agriculture are growing so fast that, if they continue to increase at the current rate, they alone could use up the safe budget for all greenhouse gas emissions by 2050.[8]

These dire drawbacks are mere symptoms. They flow from the internal logic of the model itself. The reason that industrial agriculture cannot meet the world's needs is that the structural forces driving it are misaligned with nature, including human nature.

Social history offers clear evidence that concentrated power tends to elicit the worst in human behavior. Whether for bullies in the playground or autocrats in government, concentrated power is associated with callousness and even brutality not in a few of us, but in most of us.[9] The system logic of industrial agriculture, which concentrates social power, is thus itself a huge risk for human well-being. At every stage, the big become bigger, and farmers become ever-more dependent on ever-fewer suppliers, losing power and the ability to direct their own lives.

The seed market, for example, has moved from a competitive arena of small, family-owned firms to an oligopoly in which just three companies--Monsanto, DuPont, and Syngenta--control over half of the global proprietary seed market. Worldwide, from 1996 to 2008, a handful of corporations absorbed more than two hundred smaller independent companies, driving the price of seeds and other inputs higher to the point where their costs for poor farmers in southern India now make up almost half of production costs.[10] And the cost in real terms per acre for users of bio-engineered crops dominated by one corporation, Monsanto, tripled between 1996 and 2013.

Not only does the industrial model direct resources into inefficient and destructive uses, but it also feeds the very root of hunger itself: the concentration of social power. This results in the sad irony that small-scale farmers--those with fewer than five acres--control 84 percent of the world's farms and produce most of the food by value, yet control just 12 percent of the farmland and make up the majority of the world's hungry.[11]

The industrial model also fails to address the relationship between food production and human nutrition. Driven to seek the highest possible immediate financial returns, farmers and agricultural companies are increasingly moving toward monocultures of low-nutrition crops such as corn--the dominant US crop--that are often processed into empty-calorie "food products." As a result, from 1990 to 2010, growth in unhealthy eating patterns outpaced dietary improvements in most parts of the world, including the poorer regions. Most of the key causes of non-communicable diseases are now diet-related, and by 2020, such diseases are predicted to account for nearly 75 percent of all deaths worldwide.[12]

A Better Alternative

What model of farming can end nutritional deprivation while restoring and conserving food-growing resources for our progeny? The answer lies in the emergent model of agroecology, often called "organic" or ecological agriculture. Hearing these terms, many people imagine simply a set of farming practices that forgo purchased inputs, relying instead on beneficial biological interactions among plants, microbes, and other organisms. However, agroecology is much more than that. The term as it is used here suggests a model of farming based on the assumption that within any dimension of life, the organization of relationships within the whole system determines the outcomes. The model reflects a shift from a disassociated to a relational way of thinking arising across many fields within both the physical and social sciences. This approach to farming is coming to life in the ever-growing numbers of farmers and agricultural scientists worldwide who reject the narrow productivist view embodied in the industrial model.

Recent studies have dispelled the fear that an ecological alternative to the industrial model would fail to produce the volume of food for which the industrial model is prized. In 2006, a seminal study in the Global South compared yields in 198 projects in 55 countries and found that ecologically attuned farming increased crop yields by an average of almost 80 percent. A 2007 University of Michigan global study concluded that organic farming could support the current human population, and expected increases without expanding farmed land. Then, in 2009, came a striking endorsement of ecological farming by fifty-nine governments and agencies, including the World Bank, in a report painstakingly prepared over four years by four hundred scientists urging support for "biological substitutes for industrial chemicals or fossil fuels."[13] Such findings should ease concerns that ecologically aligned farming cannot produce sufficient food, especially given its potential productivity in the Global South, where such farming practices are most common.

Ecological agriculture, unlike the industrial model, does not inherently concentrate power. Instead, as an evolving practice of growing food within communities, it disperses and creates power, and can enhance the dignity, knowledge, and the capacities of all involved. Agroecology can thereby address the powerlessness that lies at the root of hunger.

Applying such a systems approach to farming unites ecological science with time-tested traditional wisdom rooted in farmers' ongoing experiences. Agroecology also includes a social and politically engaged movement of farmers, growing from and rooted in distinct cultures worldwide. As such, it cannot be reduced to a specific formula, but rather represents a range of integrated practices, adapted and developed in response to each farm's specific ecological niche. It weaves together traditional knowledge and ongoing scientific breakthroughs based on the integrative science of ecology. By progressively eliminating all or most chemical fertilizers and pesticides, agroecological farmers free themselves--and, therefore, all of us--from reliance on climate-disrupting, finite fossil fuels, as well as from other purchased inputs that pose environmental and health hazards.

In another positive social ripple, agroecology is especially beneficial to women farmers. In many areas, particularly in Africa, nearly half or more of farmers are women, but too often they lack access to credit.[14] Agroecology--which eliminates the need for credit to buy synthetic inputs--can make a significant difference for them.

Agroecological practices also enhance local economies, as profits on farmers' purchases no longer seep away to corporate centers elsewhere. After switching to practices that do not rely on purchased chemical inputs, farmers in the Global South commonly make natural pesticides using local ingredients--mixtures of neem tree extract, chili, and garlic in southern India, for example. Local farmers purchase women's homemade alternatives and keep the money circulating within their community, benefiting all.[15]

Besides these quantifiable gains, farmers' confidence and dignity are also enhanced through agroecology. Its practices rely on farmers' judgments based on their expanding knowledge of their land and its potential. Success depends on farmers' solving their own problems, not on following instructions from commercial fertilizer, pesticide, and seed companies. Developing better farming methods via continual learning, farmers also discover the value of collaborative working relationships. Freed from dependency on purchased inputs, they are more apt to turn to neighbors--sharing seed varieties and experiences of what works and what does not for practices like composting or natural pest control. These relationships encourage further experimentation for ongoing improvement. Sometimes, they foster collaboration beyond the fields as well--such as in launching marketing and processing cooperatives that keep more of the financial returns in the hands of farmers.

Going beyond such localized collaboration, agroecological farmers are also building a global movement. La Via Campesina, whose member organizations represent 200 million farmers, fights for "food sovereignty," which its participants define as the "right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods." This approach puts those who produce, distribute, and consume food--rather than markets and corporations--at the heart of food systems and policies, and defends the interests and inclusion of the next generation.

Once citizens come to appreciate that the industrial agriculture model is a dead end, the challenge becomes strengthening democratic accountability in order to shift public resources away from it. Today, those subsidies are huge: by one estimate, almost half a trillion tax dollars in OECD countries, plus Brazil, China, Indonesia, Kazakhstan, Russia, South Africa, and Ukraine.[16] Imagine the transformative impact if a significant share of those subsidies began helping farmers' transition to agroecological farming.

Any accurate appraisal of the viability of a more ecologically attuned agriculture must let go of the idea that the food system is already so globalized and corporate-dominated that it is too late to scale up a relational, power-dispersing model of farming. As noted earlier, more than three-quarters of all food grown does not cross borders. Instead, in the Global South, the number of small farms is growing, and small farmers produce 80 percent of what is consumed in Asia and Sub-Saharan Africa.[17]

The Right Path

When we address the question of how to feed the world, we need to think relationally--linking current modes of production with our future capacities to produce, and linking farm output with the ability of all people to meet their need to have nutritious food and to live in dignity. Agroecology, understood as a set of farming practices aligned with nature and embedded in more balanced power relationships, from the village level upward, is thus superior to the industrial model. This emergent relational model offers the promise of an ample supply of nutritious food needed now and in the future, and more equitable access to it.

Reframing concerns about inadequate supply is only the first step toward necessary change. The essential questions about whether humanity can feed itself well are social--or, more precisely, political. Can we remake our understanding and practice of democracy so that citizens realize and assume their capacity for self-governance, beginning with the removal of the influence of concentrated wealth on our political systems?

Democratic governance--accountable to citizens, not to private wealth--makes possible the necessary public debate and rule-making to re-embed market mechanisms within democratic values and sound science. Only with this foundation can societies explore how best to protect food-producing resources--soil, nutrients, water--that the industrial model is now destroying. Only then can societies decide how nutritious food, distributed largely as a market commodity, can also be protected as a basic human right.
