Summary of "Long-Term Sustainability of Improved Sanitation in Rural Bangladesh"

Core Content

This technical paper examines the long-term sustainability of improved sanitation in rural Bangladesh, focusing on the impact of the 2003–2006 national sanitation campaign that aimed to eliminate open defecation and promote latrine use. The study analyzes the effectiveness of different implementation models and the role of government, NGOs, and the private sector in sustaining sanitation behaviors and facilities.

Main Points

1. Overview of the Sanitation Challenge

• 2.6 billion people globally lack access to improved sanitation.
• In Bangladesh, 75% of these people live in rural areas.
• The 2003–2006 national sanitation campaign aimed to achieve 100% sanitation coverage and eliminate open defecation by 2010.

2. Implementation Approaches

Four implementation models were used in the ODF (Open Defecation-Free) campaigns:

• GOB-only: Local government with no NGO support.
• GOB-Donor: Local government with some donor support.
• NGO-CLTS: Strong NGO support using Community-Led Total Sanitation methods.
• NGO-Non-CLTS: Strong NGO support without using CLTS.

3. Survey Findings

• 89.5% of households in ODF Union Parishads own or share a latrine that safely confines feces.
• 10.5% of households still practice open defecation or use unimproved facilities.
• 70% of households have owned their latrines for at least three years, indicating durability.
• Sustained latrine use is observed across all four implementation approaches, with similar outcomes likely due to the central government's promotion of sanitation.

4. Latrine Access and Quality

• 95% of households can access latrine materials and skilled masons.
• 74% of households know where to find a latrine pit cleaner.
• Latrine quality varies; some are unclean, especially in poorer households.
• WHO/UNICEF definitions show 52% of households have an "improved" latrine, while 37% have a "hygienic" one.

5. Social and Cultural Factors

• Social norms have shifted to accept latrine use across all societal levels.
• Women are more likely to have improved or shared latrines due to privacy and cultural practices (e.g., purdah).
• Open defecation is socially stigmatized, and those who do it face criticism in terms of marriage, village respectability, and religious purity.

6. Private Sector Role

• The private sector has matured and supports affordable access to latrine parts and services.
• Microfinance institutions can help households upgrade their latrines by connecting with service providers.

7. Factors Affecting Sustainability

• Poverty is a key factor; the two poorest wealth quintiles are more likely to continue open defecation.
• Natural disasters (e.g., cyclones, floods) may disrupt sanitation progress.
• Lack of local leadership and follow-up programs correlates with continued use of unimproved latrines.

8. Key Insights for Future Programming

• Political will from all levels of government is crucial for long-term sanitation success.
• Sustained financing and behavior change communication are essential for maintaining sanitation behavior.
• Sanitation marketing can help understand consumer needs and constraints.
• Subsidies and community-based approaches are more effective in reaching the poorest families.
• Schools and local institutions play a role in maintaining sanitation awareness.

Key Information

• The study was conducted in 53 Union Parishads, representing 481 total.
• 3,000 households were surveyed, with qualitative research in 18 Union Parishads.
• The private sector has emerged as a key enabler for latrine access and maintenance.
• Follow-up programs and local leadership are important for sustaining sanitation behaviors.
• Cultural factors, such as purdah and purity, influence the adoption of latrines.
• Government support and institutionalization (e.g., sanitation secretariat, annual development programs) have been critical in the campaign's success.

Conclusion

The study highlights that while the national sanitation campaign in Bangladesh has led to significant improvements in latrine access and use, long-term sustainability depends on continued government and NGO engagement, private sector support, and behavior change efforts. The findings offer valuable lessons for other countries aiming to scale up rural sanitation programs, emphasizing the importance of social norms, financing mechanisms, and community involvement.
