In this talk I reviewed the present status and recent progress on lightmeson scattering analyses, by means of dispersive or analytic methods. The recent application of these model independent techniques have settled the controversy about the existence and parameters of long debated light meson resonances. I will thus discuss here the state of the art and recent changes on our knowledge about the spectroscopy of light scalar mesons when observed from such scattering processes.
