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'm not sure it's actually the case that interventions in temporary emergencies are "very likely" more cost-effective. Emergencies often lead to an influx of funds that local organizations struggle to absorb, and it's difficult to allocate funds efficiently. This GiveWell blog on the topic is somewhat dated, but I think the main points still stand.
