Alex Penn and Pete Barbrook-Johnson (Senior Research Fellows in CECAN) recently delivered a bespoke 1-day course on participatory systems mapping for researchers and policy makers in the new SIPHER project. SIPHER is an ambitious systems science project focussed on public health issues at different geographical scales in the UK. It includes policy makers, embedded policy researchers, public health experts, and academic modelling experts. They were keen to learn about CECAN’s approach to systems mapping, understand its strengths and weaknesses, and how they might apply it.
