I will report on a joint work with F. Bastianelli, A. Kouvidakis and A. F. Lopez in which we study the cone of (pseudo-)effective cycles on symmetric products of a curve.   We first prove that the diagonal cycles span a face of the pseudo-effective cone of cycles in any given dimension. Secondly, we  look at the contractibility faces associated to the Abel-Jacobi morphism towards the Jacobian and in many cases we are able to compute   their dimensions.
