Can we expedite regenerative farming with UBI?

TL;DR: Could UBI for farmers be a highly effective use of philanthropic funding to pivot more food production to regenerative farming sooner? By extension, would it be a good use of my time to put a grant application to Coefficient Giving to set up UBI programs for rural farmers (ie in Vietnam) who are currently switching to industrial (harmful) techniques due to financial instability?

#idea Natural farming. One reason that farmers use industrial methods is to produce more money to escape poverty. The unpredictability of produce prices perhaps also contributes to the desire to increase yields. However, as Fukuoka mentioned, as long as the farmers are desperate, they will spend more money on improvements without any extra cost; middle-men monopolies in the supply chain, perhaps along with price stickiness from consumer demand for substitutable goods (produce), prevents farmers from making more money. But still, a fundamental driver of industrial product (fertiliser, pesticide etc) usage is earning instability.
To resolve this, what if we provided a UBI for farmers, guaranteed to three years at a time (or long enough to survive the organic transition)? Their income is guaranteed, so they are free to use methods that do not produce more profit at the expense of future sustainability? This could be an extremely effective use of philanthropic funds that I could argue for on EA.

First, let's get on the same page about UBI; UBI works. This post discusses how UBI studies in Kenya demonstrated that UBI was generally helpful, but lump sum (upfront) UBI payments over a long term (ie 12 years) produced much larger benefits (measured through eg net village revenue, number of businesses, domestic violence reduction, perceived alcohol consumption). Shorter term (ie 2 years) and regular payment (ie monthly instead of yearly) UBIs created benefits too, but less, which is troubling because most UBI pilots use short-term monthly payments, and thus are seeing suboptimal benefits.

I contacted UBI Farms to ask about their opinions on barriers to regenerative farming adoption, and whether they've explored natural farming in addition to modern techniques (ie aeroponics).

Caro mentioned that Vietnam's management of ethnic minorities may provide clues about how to integrate regenerative farming adoption with existing regenerative traditional practices used by these groups.
