Resumen
Descripción
The 2007-2008 global food crisis has
renewed interest in post-harvest loss, but estimates remain
scarce, especially in Sub-Saharan Africa. This paper uses
self-reported measures from nationally representative
household surveys in Malawi, Uganda, and Tanzania. Overall,
on-farm post-harvest loss adds to 1.4-5.9 percent of the
national maize harvest, substantially lower than the Food
and Agriculture Organization's post-harvest handling
and storage loss estimate for cereals, which is 8 percent.
Post-harvest loss is concentrated among less than a fifth of
households. It increases with humidity and temperature and
declines with better market access, post-primary education,
higher seasonal price differences, and possibly improved
storage practices. Wider use of nationally representative
surveys in studying post-harvest loss is called for.
