The study of stochastic processes in inhomogeneous environments and random environments is developing well in probability theory. In this talk I first briefly review some basic facts on contact processes. Then I introduce some previous models on contact processes in inhomogeneous environments and random environments. Finally, I report some recent works on contact processes on some inhomogeneous graphs and random graphs. Some basic ideas of the proofs are given. (The talk is based on some joint works with Xinxing Chen, Thomas Mountford, Jean-Christophe Mourrat and Daniel Valesin.)
