Phase II Data Collection
Duration: July 2000 – November 2000
Plangs reported in Form 6 were
matched to the mapped plangs based upon the names of the adjacent plang
users. Household interviewees reported the names of adjacent users for
each plang that they used. Sometimes, they reported an adjacent
username which happened to correspond to the user of a plang that was
one or more plangs away from their plang and not immediately adjacent.
For each village, the mapping informants in Phase II provided the names
of users for all plangs used by villagers in their village. In
addition, they provided the usernames of plangs that were adjacent to
and one plang away from each of the plangs that were used by villagers
in their village. Gathering the usernames of adjacent plangs and plangs
located one plang away during the mapping process would theoretically
increase the chances of finding a matching pattern in the Form 6 data.
Phase II Data Collection consisted of three main tasks:
- Group
Discussion (Mapping) – The spatial teams queried village headmen
and other village informants in order to map locations and boundaries
of farmland (plang) used by all households in each village and identify
the users of each plang. These plangs were referred to as “target
plang.” In addition, the group mapped and defined users for
immediately adjacent plang (“0 jump plang”) and plang
located one plang away from target plang (“1 jump plang”),
even if they belonged to other villages. Plangs that belonged to other
villages were referred to as “non-target” plang. Typically,
multiple group discussion sessions (~half day / session) were required
for each village.
- GPS Accuracy Check (Mobile Checking) – Using
GPS receivers and updated cadastral maps, interviewers verified the
location and user information provided by the village informants in the
group discussion sessions. At least six target plang representing at
least 6 different households were randomly selected for verification.
- Matching – Using target and adjacent plang information
gathered in the Household Survey Form 6 and in the Group Discussion,
the spatial team attempted to match each plang listed in household
survey Form 6’s with a corresponding plang mapped in the group
discussion. The spatial teams were responsible for carrying out these
tasks for the 92 intensive study villages.
