Land tenure and food security have each been the subject of extensive but g
enerally separate - research in the past. Links between the two issues are
now receiving increased attention, yet critical links between them remain u
nexplored. After a brief review of the two concepts, this article combines
both issues within a dynamic framework that recognizes not just the convent
ional link between access to land and access to food in the short run, but
also the recursive link between access to food and the ability to maintain
sufficient resources to meet long-run needs. Such a framework makes explici
t the trade-offs that poor households may face in bad years between consump
tion and investment in non-labour assets. Perhaps less intuitively, it also
suggests that the need for self-insurance may force poor households to cho
ose less efficient crops or production strategies than wealthier households
even in good years. The article concludes with a discussion of the implica
tions of these results for equity, efficiency, research, and policy.
