Dear Martha: 

I have not been able to access the article to read it, but reading the abstract, I undoubtedly agree that generating models of access to sustainable and participatory sanitation generates, replicates and scales, therefore an effect on the achievement of the SDGs, mainly the 6th. 

I can tell you about the experience in Bolivia, where the Swedish Embassy through the Aguatuya Foundation executed a project for 10 years, where basically different models of decentralized wastewater treatment plants were implemented for different communities.

Together with the participation of different actors in society, strategic sanitation plans  were developed that help visualize the appropriate technologies to provide sanitation solutions to 100% of the municipality's population. The impact after 10 years is a municipality of 20 thousand inhabitants with 100% of its wastewater treated, here a  video 

Querida Martha: 

No he podido acceder al artículo para poder leerlo, pero leyendo el abstract, sin duda estoy de acuerdo que el generar modelos de acceso a saneamiento sostenible y participativos, genera, replica y escalamiento, por consiguiente un efecto en el logro de los ODS, principalmente el 6. 

Yo puedo hablarte de la experiencia en Bolivia, donde la Embajada de Suecia a través de la Fundación Aguatuya ejecuto un proyecto por 10 años, donde básicamente se implementaron diferentes modelos de plantas descentralizadas de tratamiento de aguas residuales para diferentes comunidades.

Junto con la participación de diferentes actores de la sociedad se desarrollaron  Planes estratégico de saneamiento  que ayudan a visualizar las tecnologías adecuadas para brindar soluciones de saneamiento al 100% de la población del municipio.
El impacto después de 10 años es un municipio de 20 mil habitantes con el 100% de sus aguas residuales tratadas, aquí un video 

Hello,

My co-authors and I recently published "Rural Sanitation Sustainability Dynamics: Gaining Insight through Participatory and Simulation Modeling" as part of a virtual special issue on “Accelerating Environmental Research to Achieve Sustainable Development Goals” in Environmental Science & Technology.

I hope you enjoy the article - please feel free to reply to this thread with any questions.

Sincerely,
Martha McAlister

Synopsis:
This paper outlines a participatory, systems thinking approach which, through model building and simulation, led to insights about rural sanitation in Uganda and broad recommendations for sanitation policy and intervention design.

Abstract:
Improved sanitation provides many benefits to human health and well-being and is integral to achieving Sustainable Development Goal Six. However, many nations, including most of sub-Saharan Africa, are not on track to meeting sanitation targets. Recognizing the inherent complexity of environmental health, we used systems thinking to study sanitation sustainability in Uganda. Our study participants, 37 sanitation actors in three rural districts, were engaged in interviews, group model building workshops, and a survey. The resulting model was parametrized and calibrated using publicly available data and data collected through the Uganda Sanitation for Health Activity. Our simulations revealed slippage from improved sanitation in all study districts, a behavior reflected in real interventions. This implies that systemic changes-changes to the rules and relationships in the system-may be required to improve sanitation outcomes in this context. Adding reinforcing feedback targeting households’ perceived value of sanitation yielded promising simulation results. We conclude with the following general recommendations for those designing sanitation policies or interventions: (1) conceptualize sanitation systems in terms of reinforcing and balancing feedback, (2) consider using participatory and simulation modeling to build confidence in these conceptual models, and (3) design many experiments (e.g., simulation scenarios) to test and improve understanding.
