This document outlines a proven model to eliminate open defecation in Nadia, India. The key approaches include using community-led total sanitation to trigger behavior change, linking government and non-government organizations, community-led monitoring, and convergence with other departments. Strategies focus on raising demand, strengthening the supply chain, mobilizing resources, and monitoring construction and toilet use. Toilets are constructed and supply chains are managed through agreements with self-help groups and local governments. Lessons learned emphasize the importance of social mobilization, breaking large goals into smaller targets, women's participation, convergence, intensive monitoring, and institutionalizing systems for long-term sustainability.
