As part of the African Development Bank’s (AfDB) Annual Effectiveness Review (ADER), Fraym used high-resolution time series mapping to examine how lives have changed along a 1900-kilometer road corridor connecting Bamako, Ouagadougou, and Accra. The project was meant to facilitate trade linkages and development. AfDB’s desire to understand livelihood changes within the project area necessitated an innovative approach not limited by administrative boundaries.

Fraym generated a custom polygon that included areas within 20 kilometers of the road, and then used geotagged household survey data from before and after the AfDB-funded road project to analyze changes within the corridor.

Overall, the corridor is home to roughly one-third of the total population of Mali, Burkina Faso, and Ghana. Additionally, the corridor represents about 40 percent of the countries’ GDP.

Though not all changes are directly attributable to the project, some notable results from the before and after analysis inside the corridor include:

  • 3.4 million additional people started using advanced cooking fuel
  • The time to fetch water decreased on average by 3.3 minutes, while it increased outside of the corridor
  • The number of literate females nearly doubled
  • The number of Malian men employed in skilled labor increased by more than 15 percentage points
  • Corridor population increased from 11.6 million to 19.3 million

By using hyperlocal data, Fraym is helping clients plan more effective projects and assess population changes over time. Our data team can do this for any specialized geography in Africa.
