Any particular resource to recommend?

Both of the books "Systems Thinkers" and "The Emerging Consensus in Social Systems Theory" are nice broad introductions into the historical developments, various lines of thought, and the massive space that is systems thinking. They should both give you a good initial starting point for further research.

“Thinking in Systems: A Primer” is the best first read.

Then, “Meltdown” and finally “The Fifth Discipline”
