Abstract
It is argued that there are interconnected and dynamic factors that influence the sustainability of water, sanitation, and hygiene (WASH) services in developing countries. Five sustainability factors are often mentioned by literature: financial, institutional, environmental, technical, and social (FIETS) factors. This article aims to understand the interaction of those five sustainability factors in the context of WASH services in Indonesia. A system approach, in the form of a “modified” causal loop diagram, was utilized to analyze this interaction. The strength of influence from one factor to others were obtained from small surveys of 16 WASH practitioners and experts from international and national non-governmental organizations (NGOs) based in Indonesia and national government institutions related to WASH. It was found that institutional factor is the “leverage” factor, i.e., the most influential and least dependent, in the WASH services system in Indonesia. It means that WASH institutional strengthening is necessary to sustain WASH services in Indonesia. Furthermore, the most important feedback loop is social–WASH services. This depicts the importance of the bi-directional effect of WASH services and the social conditions of the community, i.e., the more supportive the community is, the higher the likelihood of the sustainability of WASH services, and then positively influence back the social conditions of the community. Moreover, the relationship between factors varies across context or location. Finally, this paper shows that the sustainability of WASH services involves complex interactions of the sustainability factors and understanding these interactions is critical to sustaining the WASH services or program in rural Indonesia.
Highlights
There is a high concern for the sustainability of water, sanitation, and hygiene (WASH)services, such as provision of water supply and sanitation services, in developing countries.Sustainability in the WASH services means that the WASH services remain functional, even after the WASH implementer organization leaves that place [1,2]
Sixteen WASH practitioners and experts from international and national nongovernmental organizations (NGOs) based in Indonesia and national government institutions related to WASH were involved in this study
This paper explores the interactions between factors influencing the sustainability of WASH services through the lens of the system dynamics approach
Summary
There is a high concern for the sustainability of water, sanitation, and hygiene (WASH)services, such as provision of water supply and sanitation services, in developing countries.Sustainability in the WASH services means that the WASH services remain functional, even after the WASH implementer organization leaves that place [1,2]. There is a high concern for the sustainability of water, sanitation, and hygiene (WASH). Services, such as provision of water supply and sanitation services, in developing countries. Sustainability in the WASH services means that the WASH services remain functional, even after the WASH implementer organization leaves that place [1,2]. Previous reports mentioned that many WASH services failed, especially in rural areas, water supply [3,4,5]. A lot of investment is wasted due to this problem. It was estimated that the WASH system failure in Africa resulted in a lost investment of $1.2 billion [9]. Unsustainable WASH services inhibit the progress of the UN Sustainable Development Goals 6, i.e., achieving 100% access to safely managed water and sanitation services
