The term exists, but it's not quite approved, more of a neologism. If there's a specific niché to be filled, the word could gain some ground, probably with some intellectual backing, I gather it'll be a social scientist that's more likely to use it in a specific context (excluding economists; they tend to be rather unimaginative with such things). In the meantime other expressions are used till it becomes vogue amongst generic Sub-saharan environmental policy strategists.
