Maybe these three lectures about emergence could be interesting to get a first overview of the topic. Therein Prof. De Deo explains for example that emergence has a lot to to with what new phenomena can occurre when coarse graining (or renormalizing) microscopic degrees of freedom of a large system to obtain an effective (possibly including emergent phenomena) macroscopic description.

Background material to understand and deepen the wisdom about the concepts presented in these lectures can be found here. Among these resources is this book titled "Statistical Physics: Statics, Dynamics and Renormalization". It explains not only the statistical mechanics basics, but from the authors "interdisciplinery" point of view it includes topics such as renormalization, self-organized criticality complexity, and other things which are useful and important to understand emergence (as explained in the video lectures).

I've just read some chapters of this book, it is slightly technical and very accessible, and the style of writing makes me wanting to read the whole thing.
