Sanitation value chains in low density settings in Indonesia and Vietnam: Impetus for a rethink to achieve pro-poor outcomes

© 2017 The Authors. This study examined the sanitation hardware supply chain in rural, low density settings in Indonesia and Vietnam. Actual costs along the chains were investigated to understand the challenges and opportunities to support affordable sanitation in remote, rural locations. Data were collected from four remote districts in Indonesia and Vietnam through a systematic value-chain analysis comprising 378 interviews across households and supply chain actors and both quantitative and qualitative analysis. Three main findings are presented. Firstly, poor households, often located in remote areas and with lower sanitation access, often experienced higher costs to build durable latrines than households in accessible areas or district capitals. Second, locally sourced materials (sand, bricks or gravel) had a greater influence on price than externally sourced materials (cement, steel and toilet pans), even accounting for cost increases of these materials along the supply chain. Thirdly, transport and labour costs represented considerable proportions of the overall cost to build a toilet. These findings highlighted logistical and financial barriers to poor, remote households in accessing sanitation. Findings can inform strategies to improve the availability and affordability of sanitation products and services, in particular key issues that need to be addressed through government and non-government pro-poor market-based interventions.
