Atlas of change
A recent report looks at how WaterAid is leading the way with mapping innovations, ensuring that access to water and sanitation reaches those most in need.
In the Afram Plains in Ghana, citizens started to voice their demands at district assembly meetings based on their increased awareness about the inequality of service coverage that this type of mapping exposed.

A GIS map can display information about the spatial distribution of access to water and sanitation services across the rural areas of a local government district.

In many developing countries, there is little information about the state of access to water and sanitation at the local level. This means that any water points or latrines that are built are often allocated without looking at the bigger picture and those most in need are not necessarily prioritized.
But when information about access to water and sanitation is displayed in a map, the distribution is clearly conveyed and areas of need are starkly highlighted.
In general, water and sanitation mapping captures information in three areas:
- the availability and quality of water resources, including variation under dry season, drought and extreme climate conditions (e.g. groundwater availability or levels of fluoride or arsenic);
- access to water and sanitation services (e.g. analyzing which parts of the population are underserved, or which water schemes do not function and why)
- demand and use of water supply and sanitation services for domestic, agricultural and productive purposes (such as irrigation, beer brewing, brick making, mining etc.)
WaterAid first began mapping in Malawi where it employed teams of mobile researchers to map the distribution of Malawi's existing water points in 90% of the country using handheld GPS devices. This information was then compared to information on population so that the ratio of water points to people could be accurately calculated.
Other WaterAid country programs, as well as other aid agencies, have also started to use similar mapping systems, resulting in far-reaching impacts.
In the Afram Plains in Ghana, citizens started to voice their demands at district assembly meetings based on their increased awareness about the inequality of service coverage that this type of mapping exposed.
The same data also led to a competition between sub-district councils to improve water supply and sanitation services for their constituencies.The district assembly, for its part, acted upon results by allocating, for the first time, funds for sanitation services.
The assembly started using data about coverage levels to redistribute funding for water points between sub-districts and to request additional financial resources from the national government.
WaterAid is now building on its successes so far and scaling up this innovative tool to create a true atlas for change.
