In models where the gravitino to gaugino mass ratio is bounded from below, such as gaugino-mediated SUSY breaking, we derive a lower bound on the gaugino mass parameter m_1/2. As a concrete example, we determine the parameter space of gaugino mediation that is compatible with all cosmological constraints.1+14 pages, 6 figures; v2: minor clarifications, 1 reference added, matches version to appear in JCAPHigh Energy Physics - Phenomenologytext
