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.
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.
The underlying reason industrial agriculture cannot meet humanity’s food needs is that its system logic is one of disassociated parts, not interacting elements.
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.
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.
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.
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.
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.
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. And the cost in real terms per acre for users of bio-engineered crops dominated by one corporation, Monsanto, tripled between 1996 and 2013.
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. 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.
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.
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.

What the article's author calls "industrial model", the simpler way to describe it is as capitalism. The article goes on to suggest replacing this "industrial model" with agro-ecology, which may well be a better way of farming, but it won't solve the food problem. Only replacing capitalism with the socialist system can do that.
