TAMASA is active in 3 countries:
Within each country, TAMASA’s activities are structured within a nested impact geography, consisting of four stratification levels:
- Maize area: defined as where maize is grown using the AfSIS crop mask, SPAM and national production statistics
- Maize-based systems: defined as areas within the maize area where >50% of the crop in more than half the seasons is maize
- Area of Interest (AOI): defined using intensification criteria of areas within maize-based systems where population density >25 km2 and that are <4 hours travel time to an urban market.
- Focal areas (FA): defined as areas within the AOI where TAMASA and its primary partners will conduct research and deliver outputs and impact.
