I have read several articles about looming famines later this year or next year as a consequence of the war in Ukraine (less wheat and less fertilizer exports) and possible droughts. I and other people raising money for EA-aligned charities (I'm running Effektiv Spenden) will be asked where to donate to fight this catastrophe. Maybe the "right" answer will still be that bednets, but most people won't follow that advise (I'm talking about 99.9% of people from outside of the EA-community). Any ideas on how to prepare an answer with a higher potential of engaging people with effective giving?
I don't think it's normally useful to preemptively direct aid because of the predictability issues you point out (coming famines being an exception). My point is more that there is a large value to quickly reacting to emergencies that we will miss if we only focus on systemic issues.
Aid infrastructure costs are a valid point, and that pushes the limit of how useful my point is as an abstract claim. I imagine that in many emergencies, a sufficiently effective infrastructure already exists and can be augmented if people put in a lot of effort (again leaning on the India COVID emergency example). But that's just my imagination and could definitely be wrong.
