We give an effective characterization of semi-abelian surfaces extending to the logarithmic setting the famous theorem of Enriques about abelian surfaces. In addition we will give a characterization of semi-abelian varieties in any dimension, strengthening a result of Kawamata. This is a joint work with M. Mendes Lopes and R. Pardini
