Geographically, the capital of Solomon Islands, Honiara, is a hilly city, a maze of ridges and valleys.
In front of me, concrete steps descend 30 meters down the face of a ridge, winding their way down in a gravity-defying manner; nothing else stands on the slope, it’s simply too steep.
The steps are part of a system of footpaths that link communities of thousands of people below to the main public road above.
Over the past 60 years as Honiara has developed, so too have informal settlements. These are often located at the bottom of steep valleys without basic services such as roads, water and electricity.
