The problem is that political instability makes it very hard for long-term planning & efforts. If you're unsure what the political winds will bring next year, or who might be in power and how it will affect you, why would you invest in a long-term cash crop that takes years to pay off? To make sure you can provide for your family, you'd be wiser to focus on the food-crop harvest that's just a few months away, which is exactly what Haitian farmers do.
That makes "chasing charity" desirable: if you can't risk personal effort & cost for long term goals (see above), then by all means leverage what you can out of short-term donations. Practically all the infrastructure and equipment used by farmer cooperatives and associations were plopped down by an aid agency or nongovernmental organization. ... in turn, there are few incentives to make repairs when equipment fails, or to want to achieve long-term success generally. ...the [donated] gear is much too large for the low coffee yields and production levels in the country, and built in a style more suited for Central America. These aid-built facilities wind up operating at extremely low capacities and consequently with high labor, fuel, and water requirements. Most of them are so inefficient that they can't even break even—or at least they wouldn't be able to without support from outside aid groups.
There's a great deal more explaining this. RT*A.
The primary lesson though is that aid organizations can't handle a military without another military backing them. The UN couldn't make that happen, so the result was to promote conflict in the end.
Truly, that isn't even remotely analogues to the situation in Haiti.
The fastest way to make money from coffee is aid agencies.
If there was more long term thinking then the actual coffee would be a better way to make money. If there was no aid then ??? I'm not sure - either they would abandon coffee entirely, or they would be forced to actually try to grow coffee.
Coffee is a tree it takes many many years to grow and develop. It's quicker to "harvest" money from aid agencies.
PS. Your reply is very strange, since the answer to your question is quite obvious. Are you actually trying to get info, or are you trying to push the message you desire via questions?
