THE INFLUENCE OF DESIGN, DEVELOPMENT AND PRESERVATION

The Barcelona superblock: lessons for our cities and the health of their residents

 

While current urban designs for new suburbs in cities across Australia are an improvement on post-war suburban residential developments, the result is still one that leaves suburban residents highly car dependent, with limited public transport (PT) access and scant opportunity to walk or bicycle to local amenities. As a consequence of Australian cities pursuit of urban sprawl, work journeys continue to lengthen in time and space, traffic congestion worsens, transport emissions rise, and inequality of economic and health outcomes for those living in these suburbs continues to grow relative to the whole population.


Researchers from the Transport Health and Urban Design Research Lab at the University of Melbourne (https://thud.msd.unimelb.edu.au/) collaborated with researchers from Spain to explore the co-benefits associated with an urban model that may have utility if applied in Australia. The research undertaken in Barcelona, Spain and recently published in Environment International demonstrates that substantial health benefit for the whole population can be attained if large “superblocks” (400m x 400m) are created from relatively dense residential blocks of 150m x 150m, which are currently surrounded by normal busy streets.


The co-benefits associated with creating these superblocks is considerable. The research highlights opportunities to reduce premature mortality rates and increase life expectancy through reductions in air pollution, noise and heat and increased access to green space, and transport-related physical activity. The economic effects of transforming the existing urban form are also impressive, estimated to be 1.6 billion euros, mainly coming from the increase in life expectancy, a 20% reduction in premature mortality, and a 13% reduction in overall burden of disease.


The paper presents the results in more detail and explores how such a model might be relevant to or applied in Melbourne and other sprawling Australian cities.
