This study uses five rounds of household panel data from Tigray, Ethiopia, collected in the period 1998β2010 to assess the impacts of a land registration and certification program that aimed to strengthen tenure security and how it has contributed to increased food availability and, thus, food security in this food-deficit region. Results show that land certification appears to have contributed to enhanced calorie availability (calorie intake), and more so for female-headed households, either through enhanced land rental market participation or increased investment and productivity on owner-operated land. Results also show that members of households that accessed additional land through the land rental market had a significantly higher body mass index.Non-PRIFPRI1; ESSP II; Theme 6; Subtheme 6.2; GRP32; CRP2DSGD; PIMCGIAR Research Program on Policies, Institutions, and Markets (PIM
