For all but a few agrarian countries heavily dependent on tobacco farming (such as Zimbabwe and Malawi), a drop in demand for tobacco would not lead to massive job losses, according to the bank.
Their reluctance has been put down to ignorance (farmers do not appreciate the benefits of fertiliser until they have tried it), timidity (they are wary of upfront commitments of money and prefer farming that delivers a reliable, even if low, return) or illiquidity (farmers cannot get the credit they need to afford seeds and fertiliser).
