How to feed the world

 In 2009, ETC Group (Action Group on Erosion, Technology and Concentration) published a report titled Who Will Feed Us? in which they cite the statistic that small-scale farmers feed 70 percent of the world (that is, they produce 70 percent of the food that actually goes to feeding people, vs. crops that are diverted for biofuels, animal feed, or other non-food uses). This distinction is important—they aren’t claiming that smallholder farmers produce 70 percent of net calories, but 70 percent of the food that ends up being consumed by people.

They assert, based on available data, that 50 percent of global crop production for human consumption can be attributed to small-scale farms under 5 hectares (this is relatively uncontroversial in the research). Then, they added in food resulting from practices like hunting and gathering, fishing, pastoralism, as well as small-scale urban and peri-urban food production, which accounted for an additional 20 percent of food consumed. These forms of food production are mostly informal—and chronically undervalued—so it’s difficult to ascertain exact figures, but they are nonetheless important ways that people feed themselves around the world.

Two papers, published by Vincent Ricciardi et al. (2018) and Sarah Lowder et al. (2021), both claim that small-scale farmers account for just 30 percent of global food production—quite a jump down from 70 percent. This has led to a slew of headlines implying that these findings prove that small-scale agriculture is inefficient and incapable of feeding the world and that we should invest in industrialised methods instead. 

The studies were full of methodological errors and assumptions that warrant further scrutiny.

They measured crop production for small-scale vs. industrial farms, completely neglecting how much of that food is going to feed people. The reality is that industrial farms divert a significant percentage of crops to biofuels, animal feed, and other non-food uses. Even calories grown for animal feed, which could be argued to still be contributing to food security, are highly inefficient; nonprofits GRAIN and IATP estimate that for every 100 calories fed to animals, only 17 to 30 end up in the meat that humans consume. Measuring production alone doesn’t tell us much about food security.

Their dataset included only 55 countries (or two-fifths of the global population). Over half of these countries are European, where small-scale farming is, indeed, more marginal. The researchers ignore large swaths of Africa, South East Asia, and other regions where small-scale farmers account for a significant percentage of food production. And yet they make sweeping claims about global peasant food production.  It’s nonsensical to rely on a dataset that erases the vast majority of countries where small-scale farmers exist, neglect to include the majority of food production methods they employ, and then make claims about their ability to feed the world.

Ricciardi’s team referenced another study in 2016 that uses a dataset that includes far more Majority World countries. They found that if they applied their methodology to this dataset, they would reach the conclusion that 76 percent of food calories are produced by farms under five hectares, which is significantly higher than even ETC.

Lowder et al.’s paper made the assumption that land and production have a correlative relationship; if large farms make up 80 percent of the agricultural land, then large farms must make up 80 percent of food production. But the reality is that not all farms are equally productive. Small farms tend to outproduce larger ones per hectare. Lowder’s paper assumes that since small farmers only occupy a small portion of land, they must also only produce a small portion of the food. But that’s the whole point — while small farmers do occupy a small portion of the land, they (a) produce more than large-scale farms per hectare, and (b) devote more of their food to people, rather than non-food uses. They’re also able to produce food using significantly fewer resources and without industrial agriculture’s huge environmental and social externalities. Second, for many large farms (more so than smaller farms), a significant percentage of produced calories are diverted to biofuels, animal feed, and other uses. Again, Ricciardi et al. found that farms under 2 hectares devote a greater proportion of their production to food, while farms over 1,000 hectares have the greatest proportion of post-harvest loss. Simply measuring production doesn’t tell us very much about food security. And yet, production remains the dominant metric.

Both papers also define a “small farm” as a farm under 2 hectares, when the FAO itself has stated that creating a standard cutoff for farm size is unwise because what is considered “small” varies from country to country.

These two papers have led to when you search “how much of the world’s food do smallholder farmers produce,” these are the results that come up, based on research that is, at best, deeply flawed. Their assumptions make their research basically useless for determining which agricultural path we should pursue, taking all externalities and environmental impacts into account. The implications of these papers justifying industrial agriculture are dangerous. We cannot measure success on production alone. We must begin widening the metrics to include biodiversity, environmental impact, and equity.

The debate places the onus unfairly on peasant and small-scale farmers to prove they can produce enough food to feed the world (even though we have ample country-level data showing that small-scale farms outproduce large-scale farms). We must ask, then, why the onus is not placed on industrial agriculture to justify why the percentage of the calories they deliver to people is so low; why there is so much waste; why so many calories are inefficiently allocated while using such vast amounts of land and resources.

It just seems implausible to those who accept capitalism that small-scale farming really can be more productive per-hectare than large, industrial farms. But most of the world does not get their food from industrial sources. Some believe that they should. But the industrial system’s efficacy is far from proven, especially when loss, waste, and non-food uses are taken into account. In fact, the evidence points squarely in the opposite direction. As the climate crisis deepens, we are collectively waking up to the immense harms of the industrial system — environmental degradation, corporate consolidation and exploitation.
