Résumé	Ethnographic mapping is a fieldwork technique in which the researcher — rather than the participants — systematically records a community's physical and social space: the layout of households, the placement of resources such as wells, markets, and fields, the boundaries people recognize, and the routine paths along which people and goods move. Sketch maps drawn in the field and georeferenced coordinates captured with GPS are treated as primary ethnographic data, not mere illustration. The resulting map anchors observation, sampling, and interpretation in the concrete geography of social life.	The key-informant interview is a purposive in-depth interviewing technique in which the ethnographer works closely with a small number of especially knowledgeable or well-positioned community members rather than a representative sample. Key informants are people who, by experience, role, or position, can articulate cultural knowledge a typical member could not. The method centers on selecting such people well, building genuine rapport, eliciting their expertise through ethnographic questioning, and cross-checking what they say against other informants and observations to guard against bias.
