The HBE Linkages Toolkit describes how population health is influenced by the design of our neighbourhoods, housing, transportation systems, natural environments, and food systems.  It brings together research based key messages that correlate land-use planning decisions, impacts on the built environment and population health. Victoria Barr assisted with the initial literature review for the Toolkit in 2012, then integrated new knowledge about economic co-benefits of healthy built environments and links between those environments and social well-being, for the updated version, released in 2018.
