Economics of Sanitation Initiative: What Are the Economic Costs of Poor Sanitation and Hygiene?

The Economics of Sanitation Initiative, launched in 2007 with a WSP study from East Asia, found that the economic costs of poor sanitation and hygiene amounted to over US $9.2 billion a year (2005 prices) in Cambodia, Indonesia, Lao PDR, the Philippines, and Vietnam, affecting a total population of more than 400 million. The groundbreaking study was the first of its kind to attribute dollar amounts to a country’s losses from poor sanitation.

Factors Associated with Achieving and Sustaining Open Defecation Free Communities: Learning from East Java

This research brief discusses what it takes to bring about sustainable sanitation behavior change, cost-effectively, and at scale. Some of the findings: open defecation free (ODF) communities represent the most efficient model for scaling up sustainably; ODF outcomes that materialize late, after many months of triggering, should be subject to intensive verification and periodic recheck; and sanitation behavior change is difficult to ignite in riverbank and waterfront communities and special strategies are needed.

Digging In, Spreading Out and Growing Up: Introducing CLTS in Africa

This paper draws on the extensive involvement of Kamal Kar with the spread of CLTS in Africa to describe the early stages of the process, elaborate on its developments, and outline insights into the circumstances and features that have facilitated its rapid spread. It also discusses challenges, however, noting several issues that may limit its impact and hinder its dissemination.

Revisiting the Midnapore Model after Ten Years of Total Sanitation Campaign (TSC) in India

This paper discusses the Midnapore model of sanitation, adopted by the Indian government as a role model of Total Sanitation Campain (TSC). In doing so, the paper examines the factors behind the success of the model, which during the process of replication were probably overlooked. The paper also tries to address some policy level problems in the implementation of TSC.

Improving Sanitation at Scale: Lessons from Total Sanitation and Sanitation Marketing (TSSM) Implementation in East Java, Indonesia

The Gates Foundation contracted Mathematica Policy Research to conduct a retrospective implementation study to understand how the TSSM program was implemented in Indonesia, to learn more about how program monitoring data were collected, and to reconcile some apparent discrepancies between program monitoring data and impact evaluation data involving program progress. This report describes the findings from this study.
