  In this talk, based on \cite{Kane:2001rb}, we emphasise that intermediate
scale supersymmetric inflation models are particularly attractive since
inflation, baryogenesis and the relic abundance of cold dark matter (CDM) are
all related by a set of parameters which also affect particle physics collider
phenomena, neutrino masses and the strong CP problem. We also point out that
the present day relic abundances of different forms of matter are (in
principle) calculable from the supersymmetric inflation model together with a
measurement of the CMB temperature and the Hubble constant. From these relic
abundances one can deduce the amount of the present day dark energy (DE)
density.
