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 people see the "right" answer as bednets even today.
GiveWell maximum impact fund and the very similar EA global development fund seem to me to be more recommended choices, in part because of time-sensitive opportunities like you mention ( e.g. grants on covid-19 in 2020 )
As mentioned in another comment, the maximum impact fund is also funding malnutrition treatment
