The study has been conducted from July 2019 to October 2019 with the key objective of identifying opportunity, ability and motivations of the focus sanitation behaviours. The research broadly followed the SaniFOAM approach. SaniFOAM is a useful framework for organizing and analyzing the behavioral determinants of sanitation which uses a classification system commonly used in the fields such as – consumer behavior, social marketing, and organizational management, to categorize sanitation behavioural determinants under three headings: opportunity, ability and motivation. The study used qualitative data collected from various stakeholders through focus group discussions, key informant interviews and in-depth interviews. The study has identified behaviour change communication (BCC) strategy for both population (slum and non-slum) and institutions. The findings of the research also demonstrate that the relevant authorities play a vital role in decision making and implementation of policies as far as sanitation behaviours are concerned.
