How to Strengthen Market-Based Sanitation Strategies Using a Geographic Information System
![](/themes/custom/fsn2020/assets/img/transparent.png)
This learning note presents the main ideas behind a basic approach to using a geographic information system (GIS) to establish geographic segmentation as part of a market-based sanitation (MBS) strategy. Use of a GIS assumes that the most densely populated, most accessible zones are characterized by a more dynamic economy, making them easier to tap into to develop a sanitation market that is currently nonexistent or, at best, barely exists. This project aimed to support the BHA-funded Resilience Food Security Activities in Niger to develop a comprehensive market development strategy focused on the availability and supply of improved latrines and handwashing-related products in the Maradi and Zinder regions of Niger.
