When we talk about basic ag tech, we're not talking about drones or robots, we're not even talking about mechanization, it's mostly fertilizer and seed breeding.

- The accumulated knowledge of crop science is pretty strong, it's not a secret what the limiting factors in cereals crops are.

- Empirical results (see groups like The One Acre Fund, extensive research farm results in the region, high confidence RCTs leave basically no doubt)

- For US farmers prior to ~1930, they had the same average yields as Kenya does currently. In fact, fertilizer usage and yield have a very strong correlation and Kenya has a very similar curve.

Are there factors besides inputs that can impact yield? Absolutely. You could see from satellite imagery the places where conflict reached in Syria by harvest time as that conflict was developing. Market access and infrastructure in Kenya are super hard also, fertilizer is more expensive in rural Kenya than it is in the United States even though the consumers are much poorer.

Basically, there are certainly places that we're not a good fit for. I don't think we could operate in places with active conflicts like South Sudan, but Africa's a real big place. Kenya is quite stable and has effective if not formalized property rights for most smallholders. The thing I always try to remember is that America had very similar problems. The area that is now the great bread basket of the world also used to be referred to as "The Wild West."

That doesn’t address the core issue of rule of law and property rights though. Pick any number of countries in Africa and air drop them ag-tech that’s 50 years into the future. I don’t for a second believe that it would cause much of anything to change or improve.

Your US example appears to have been constrained by the current tech and knowledge of the day. In Kenya like you bring up, they aren’t limited by those things but rather lack of rule of law and property rights. So how can you compare them apples to apples?

This isn’t a chicken or egg thing. Rule of law and property rights are the necessary condition to allow people and society to grow and flourish. You can’t skip those necessary steps.

I mean look at the agricultural output for Zimbabwe for reference.

Hey, I'm sorry but I truly don't understand what you're trying to say. I want to try and understand where we disagree, because to me that usually indicates we're having a communication failure. I think this is an empirical question and I feel like it's been settled at every level, and so I'd like to understand at what level we're disagreeing.

Things I believe:

- At the plant level, crop science has shown fertilizer and seed breeding are by far the dominant factor that control the first 75% of yield above wild types of maize/corn.

- One Acre Fund RCTs have shown that providing seed and fertilizer substantially improve yield outcomes.

- At the macro level, the development path of most countries that have transitioned out of agricultural economies have correlated extremely well with fertilizer usage. From the US to China, yield correlates really, really well with fertilizer usage and minimally with things like rule of law indexes of property ownership.

Which level or statement do we disagree at?
