_Source:_ Authors’ analyses based on baseline and endline survey data.

_Note:_ HH stands for household. Calculation of food insecurity status based on self-experienced events of food insecurity, based on Household Food Insecurity Access Scale (HFIAS). MWS stands for microwatershed. Kebele is the lowest administrative unit in Ethiopia. Robust standard errors in parentheses, clustered at the mws level. Significance levels indicated as following: *** p<0.01, ** p<0.05, * p<0.1.
