Caught Short: How a Lack of Access to Clean Water and Decent Toilets Plays a Major Role in Child Stunting. WaterAid, July 2016. WaterAid’s new report reveals the extent of the global stunting crisis and the impact a lack of clean water and decent toilets is having on the future of millions of children suffering from malnutrition.
Quantifying Accessibility and Use of Improved Sanitation: Towards a Comprehensive Indicator of the Need for Sanitation Interventions. Nature, July 2016. Results show how a good indicator of the need for sanitation and hygiene interventions can combine evidence of both access and use, from self-reports and objective observation. Such an indicator can inform decisions about sanitation-related interventions, and about scaling programs up or down.
Supporting the Rights of Girls and Women through Menstrual Hygiene Management (MHM) in the East Asia and Pacific Region: Realities, Progress and Opportunities. UNICEF, July 2016. UNICEF provides an overview and analysis of the experiences of girls and women, to establish the current status of MHM programming and action across the region.
Water and Sanitation Entrepreneurs in Indonesia, Vietnam and Timor-Leste: Traits, Drivers and Challenges. Institute for Sustainable Futures, 2016. This paper explores the entrepreneurial traits, motivations, and challenges of different types of water and sanitation entrepreneurs in Indonesia, Vietnam, and Timor-Leste. It also looks at the socio-cultural dynamics that affect women’s involvement in leading water and sanitation enterprises.

Learning from Sustained Success: How Community-Driven Initiatives to Improve Urban Sanitation Can Meet the Challenges. World Development, July 2016.
Authors: Gordon McGranahan, Diana Mitlin.
Past research by one of the authors of this paper has identified four key institutional challenges that community-driven initiatives to improve sanitation in deprived urban settlements face: the collective action challenge of improving community sanitation; the coproduction challenge of working with formal service providers to dispose of the sanitary waste safely; the affordability challenge of reconciling the affordable with what is acceptable to both users and local authorities; and the tenure challenge of preventing housing insecurity from undermining residents’ willingness to commit to sanitary improvement.
In this article we examine how two well-documented, relatively successful and longstanding initiatives, the Orangi Pilot Project and an Alliance of Indian partners, met these challenges. They were met through social innovation, but also through the choice and development of sanitation technologies (simplified sewers for OPP and community toilet blocks for the Indian Alliance) that provided traction for the social innovations. We also explore more recent efforts by civil society partnerships in four African cities, demonstrating some of the difficulties they have faced in trying to overcome these challenges. No equivalent models have emerged, though there has been considerable progress against particular challenges in particular places.
These findings confirm the importance of the challenges, and indicate that these are not just challenges for social organization, but also for technology design and choice. For example, the problem with household pit latrines is not that they cannot physically be improved to sufficiently, but that they are not well-suited to the social, economic and political challenges of sanitary improvement at scale. The findings also indicate that a low economic status and a tendency to treat sanitation as a private good not suitable for public support also makes the sanitation challenges difficult to overcome.
The Developing World Urgently Needs Phages to Combat Pathogenic Bacteria. Front. Microbiol., 08 June 2016. Authors: Tobi E. Nagel, Benjamin K. Chan, et. al.
With the growing global antimicrobial resistance crisis, there is a critical need for alternatives to conventional antibiotics, especially in developing countries. Virulent bacteriophages (phages) represent a viable antibacterial technology that could be particularly beneficial, since phages are active against antimicrobial-resistant bacteria, easy to isolate from contaminated environments, and relatively inexpensive to produce.
We discuss here examples of infectious diseases that significantly affect developing countries, phage applications that could be especially impactful in those settings, and special considerations for implementing phages in the developing world.
Co-composting of solid waste and fecal sludge for nutrient and organic matter recovery, 2016. Colombo, Sri Lanka: International Water Management Institute (IWMI). CGIAR Research Program on Water, Land and Ecosystems (WLE).. 47p.
Authors: Cofie, Olufunke; Nikiema, Josiane; Impraim, Robert; Adamtey, N.; Paul, Johannes; Kone, D.
Biological treatment, composting, in particular, is a relatively simple, durable and inexpensive alternative for stabilizing and reducing biodegradable waste. Co-composting of different waste sources allows to enhance the compost nutrient value. In particular, integration of ‘biosolids’ from the sanitation sector as potential input material for co-composting would provide a solution for the much needed treatment of fecal sludge from on-site sanitation systems, and make use of its high nutrient content.
This research paper elaborates in detail the main parameters that govern the co-composting process as well as factors that control the production of a safe and valuable quality compost. It further explains technological options to tailor the final product to crop and farmer needs.
Identification and quantification of pathogenic helminth eggs using a digital image system. Experimental Parasitology, July 2016.
Authors: B. Jiméneza, C. Maya, et. al.
A system was developed to identify and quantify up to seven species of helminth eggs (Ascaris lumbricoides -fertile and unfertile eggs-, Trichuris trichiura, Toxocara canis, Taenia saginata, Hymenolepis nana, Hymenolepis diminuta, and Schistosoma mansoni) in wastewater using different image processing tools and pattern recognition algorithms.
The system allows the helminth eggs most commonly found in wastewater to be reliably and uniformly detected and quantified. In addition, it provides the total number of eggs as well as the individual number by species, and for Ascaris lumbricoides it differentiates whether or not the egg is fertile.
The system only requires basically trained technicians to prepare the samples, as for visual identification there is no need for highly trained personnel. The time required to analyze each image is less than a minute. This system could be used in central analytical laboratories providing a remote analysis service.
