A few years ago I read a book about the potential danger from the sky. The book pointed out that the Southern Hemisphere has only about 1 tenth the number of observers that are at work in the Northern Hemisphere. This includes both professional and amateur astronomers. The book suggested helping interested folk in the SH acquire telescopes and communications to help watch for these dangers.
It’s true, and one problem in the southern hemisphere is that most of the Earth’s land surface is n of the equator. Equatorial observatories can (over the course of a year) view all or almost all of the sky, but need to be at high altitude for the lower temps.
