No10, Thayu, Mabatini & Mashimoni – A pilot within a pilot
Our biggest focus during this pilot project in Mathare was on four villages: Mathare No10, Thayu, Mabatini, and Mashimoni. This is because our local partner (Community Cleaning Services) operates in the area and also because we wanted to test our capacity – figuring out how much can be done in the limited amount of time.…

Why Map Open Drainage? And How?
I believe that the reasons to map open drainage in the slums are well known and are obvious to most people. Everyone who’s ever been to the slums knows that open drainage presents a huge health hazard to the people living around it. In combination with poor or non-existent water and sanitation systems, open drainage…

The American Association for Advancement of Science (AAAS) donated us a WorldView-2 image (read more) with 6% cloud cover, taken on 30th of June 2010. It covers the areas of Mathare Valley, Korogocho, Kariobangi, Baba Dogo, as well as part of Kasarani, Dandora, and some surrounding areas. Altogether, the imagery is of a broader eastern…

Base map of Mathare is complete!
We’ve completed the base map of Mathare. It took us 17 days during which 15 mappers (on average each day) would map and edit for an average of 5 hours per day. That accumulates up to 1250 man hours. Of course the exact figure of man hours is much lower mainly due to a limited…

We are trying to get different groups to host us so we can be closer to…
