Abstract: In this paper we focus on two main aspects of planetary nebulae (PNe) as stellar and galactic evolutionary constraints: (1) PNe as probes of AGB evolution across metallicities, where both the Galactic and Magellanic Cloud PNe are studied together, and (2) PNe as probes of galaxy disk evolution. For the first topic we rely on two Spitzer Space Telescope IRS surveys of Magellanic Cloud and Galaxy PNe, where the nature of PN morphology was found to be closely related to their dust type. The second topic illustrates a series of spectroscopic observations of Galactic, M33, and M81 PNe and H II regions, comparatively studied to determine the evolution of their radial metallicity gradients.
