de Sitter vacua in String Theory are usually constructed using effective four-dimensional theories that appear to descend from string theory compactifications with fluxes and localized objects. However, in most constructions it is not clear whether the needed ingredients can be combined directly in String Theory without leading to inconsistencies.

A parallel line of inquiry, based on the properties of consistent effective field theories and known as the Swampland Paradigm, conjectures that these constructions will always be inconsistent. 

This workshop aims to bring together experts on top-down and bottom-up de Sitter constructions, discuss progress and controversies in this area and create the framework for new collaborations and developments.
