**2.1. Primary data collection**

Primary data collection is generally based on field survey comprising three main parts: (a) household interviews, (b) key informant interviews, and (c) focus group discussions.

The research team, led by the principal investigator, visited ten villages in Thatta, Sujawal, and Badin districts in Sindh and in the Gwadar district of Balochistan. The team was assisted by representatives of the communities for interpretation and to translate the questions and answers for both parties (**Figure 3**).
