A household survey of 550 paddy farmers across the ten Jelapang, sampled by stratified probability-proportional-to-size. It collects the socio-economic drivers of paddy abandonment that feed the Phase II Random Forest and the Phase III prioritisation index.
Locations: stratified PPS sample, Table 3.4 allocation (n=550). Active parcels from the v3 paddy product; inactive from the v9 amplitude classification. Active:inactive split is proportional to each zone's mapped abandonment rate. Sampling design after Olofsson et al. (2014).

Enumerators ask the farmer these questions on an ODK Collect tablet (GPS auto-tagged). Land status is the farmer's own report, never an enumerator's visual judgement.
