Slum upgrading

A Cochrane review on the impact of slum upgrading was published last month, looking specifically at the impact of improving physical environments and infrastructure. The most common interventions were improvements in water supply, sanitation, drainage, roads, paved footpaths.

The main finding is a reduction in incidence of diarrhoea due to improved water connections, with mixed results on parasitic infections or other communicable diseases and insufficient evidence on many other impacts. They also call for involvement of independent researchers early on in implementation (since most studies found were post-hoc evaluations) and for more studies to include process evaluations and qualitative evidence.

Find a great summary of it here.
