Drought and other factors had caused migration in Mozambique. There were many communities who unknown to the government who were living without health services. Local authorities worked with community health workers to map these communities using web applications. I followed one health worker, Fernando, to map a remote community. Fernando would travel on his motorbike for days through the bush, and we followed him by car and when necessary, by foot. This mapping would eventually mean that authorities could plan services and these communities would eventually receive better access to health, education and basic sanitation.
