Author calculation. See Additional file 1: Appendix A for the description of the variables
^aWe assume that the soil quality is changing across time owing to erosion and nitrogen leaching
^bThe Productive Safety Net Programme (PSNP) is a welfare improvement program by the Government of Ethiopia to the food-insecure households. The household exposure to the program changes across time
^cSee Additional file 1: Appendix A for detailed information about the Activity of Daily Living Index and a full description of all variables
