I don't know but there might be some grassroots level organisations and/or societies that I could imagine they'd like to help at the on going areas of crisis. I'm not anymore in the activist scene that I used to hang with in the 90's,
but I could imagine some things have continued in a way or another.
There are for sure a spontaneous, international grassroot people still around somewhere like the
Food Not Bombs.
At least in millenium 2000's there was an leftwing independent media group active called the
Indymedia.
Their intention was to give and make news about activist things that are more independent.
I don't have any idea are they working on the topic or even about their present state are they still active.
If you go further and ask the Red Cross about getting to a volunteer and helping somehow, they'll tell the methods for sure. There must be some.
...ok at least they've still their websites. There are wiki articles available of them if you're interested.
