The string theory Swampland programme aims at distinguishing quantum field
theories which can be completed into quantum gravity in the ultraviolet
from those which cannot. I will outline relations between different
conjectural properties of the Swampland, showing how a coherent picture is
emerging, and discuss a proposal for the microscopic physics underlying
the conjectures. I will then focus on the Swampland de Sitter conjecture
which proposes that there are no de Sitter vacua in string theory,
implying that dark energy cannot be a cosmological constant. In
particular, I will show how it can be related to the other conjectures.
