The PLURIS conference series is a biennial event for Integrated and Sustainable Urban, Regional and Spatial Planning, initiated in 2005 through a partnership between Portuguese and Brazilian researchers.

Held alternately in Brazil and Portugal, PLURIS fosters a highly multidisciplinary environment, integrating presentations on the major themes that structure regional and urban systems, encompassing all their sub-systems such as planning, management, the natural and built environment, mobility, and energy.
