Definition
The lowest level of geographic aggregation covered by the data is zones. These either correspond to existing administrative units, or were zones created for this study by the Program national teams by dividing administrative units into relatively homogenous sub-units. This was the case in:
- Madagascar, where Alaotra and Antsirabe regions were divided in two zones (1 and 2)
- Mexico, where the Sotavento region was divided in two zones (Terras Bajas and Sierra Santa Marta)
- Senegal, where Mekhe and Senegal River Delta were divided in two zones (1 and 2).
For detailed information on the rationale corresponding to the definition of each zone, the data users can refer to the National Reports.
