DETAILS OF SAMPLE SURVEY DESIGN 181
of use for the organic fertilizers for a oneproduction
cycle (January to December
2003) was measured by counting the number
of mats under each type of organic fertilizer.
To minimize the measurement error,
the interview was conducted in the plot,
and the farmer showed the enumerator parts
of the plantation that were treated with
the organic fertilizers as the enumerator
counted mats in the area. For mat management
practices, color photographs were
used to enhance the farmer’s recognition of
the practice being surveyed.
Social Capital Schedules
Social capital data were collected through
discussions with key informants and the
sampled households. Key informants (the
local leaders and village elders) were interviewed
about village social homogeneity (in
terms of ethnicity and religious affiliation)
and formal and informal organizations.
The schedule on associations recorded
information on household membership; the
level of household participation; major activities
of associations; benefits to the members;
and composition, function, and leadership
quality of associations. These were
measured following the work of Narayan
(1997). Social networks, trust, and solidarity,
as well as historical rules and regulations,
were measured in other instruments
as part of the thesis by Katungi (2006) but
are not presented here.
