While the article is about general food drives, emergencies
do introduce a bigger problem of scale and management that come and go quickly.
I volunteer with and donate to a group - https://adrn.org/ - and that's what we do. When Hurricane Harvey hit, they (I was traveling) mobilized 150+ churches around central Texas to support the coast with food, supplies, and transportation immediately after it hit. Further, we've supported cleanup operations and helped get people back on their feet.
One of the things I've helped with directly is developer our playbook so other groups worldwide can learn from what we've done and build the infrastructure and relationships to prepare in advance.
By working with smaller organizations, the closest to the problem, you get great perspective but backed by larger teams who can coordinate across a city, region, or country.
It's business management + crisis response.
