Feeding the world with organic food

I have seen discussions on sustainable / organic / agro-ecological / nature-friendly farming derailed by this:

“How are you going to feed ten billion people with organic farming?”

Some things to say to this:

1. We grow enough. Global output is around 1.5x what we need in calories. People go hungry from poverty and distribution, not from farms producing too little.

2. Most calories grown don’t feed people. A large share of grain goes through livestock’s digestive tracts. We get a tenth to a third of those calories. “Feed the world” is often a defence of cheap feed-grain meat and eating too much food.

3. Industrial yield is more expensive than it looks. Industrial ag books the output and hides many costs — soil depletion, drained and polluted aquifers, fossil-gas nitrogen, lost pollinators. It is extractive rather than productive.

When you price in those external costs, cheap food turns out expensive.

Extraction gets more expensive as it goes. As soil fertility is spent and supportive insects disappear, you buy more nitrogen, water and spray to hold the same yield. Regenerating soil runs the other way.

4. Nutrition v. tonnes. Industrial farming measures success in tonnes. It spent decades breeding varieties for yield, uniformity, shelf life, transportability and machine-harvesting; nutrient density isn’t on the list, so it gets traded away. The result is produce that’s bigger, more uniform, longer-lived but nutritionally thinner per unit weight. A “high-yield” hectare can deliver less actual nourishment. If the point of farming is to feed people rather than fill silos, the right unit is nutrition per hectare. On that ruler the gap narrows or flips.

5. Feeding ten billion isn’t one harvest, it is about getting to 2080. Mining the soil to win this decade means we lose the century.

6. Industrial ag says killing insects raises production. But for every pest the chems kill, they take out bees, hoverflies, lacewings, parasitic wasps, ground beetles and so on. Three quarters of leading crop types depend on pollinators. The current system kills its own natural labour force and labels the funeral as “productivity.”

7. Nobody is proposing kitchen gardens only. Strategies include agroecological intensification, diet shift, less waste and some redistribution. “Ten billion” is a way to dodge these by pretending hectare-yield is the only important number.

In summary, the problem is not really about production. It is about distribution, diet and transparent accounting. Industrial farming “wins” on yield only by leaving before paying its bills (including the wages of the insects that do the work.)

Another version of the original question is “how will we feed ten billion people within several decades while keeping our meat habits, maintaining generous waistlines, binning a third of it, and allowing certain politicians, engineers and industrialists to get away with avoiding difficult truths?”
