Public sector provision of improved seeds in developing countries has
often fallen foul of government failure, while commercial seed supply
has faced unusually high transactions costs and some market failure. B
oth have met difficulties in providing appropriate seed for marginal f
arm lands. Into the gap have come nongovernmental organisations (NGOs)
, most of them involved in small-scale seed multiplication and distrib
ution. Evidence from a review of 19 NGO programs suggests that their s
eed activities operate on a small scale, sometimes with little distinc
tive technical competence, and tend to ape other formal sector methods
. Above all, they face a challenge in making their efforts sustainable
: the most promising avenue seems to lie in their supporting the growt
h of small seed production and distribution enterprises at farm and vi
llage level.
