While child mortality rates have plummeted worldwide, . Children who are stunted (having low height-for-age) suffer from a long-term failure to grow, reflecting the cumulative effects of chronic deficits in food intake, poor care practices, and illness. The early years of life, especially the first 1,000 days, are critical; if a child’s growth is stunted during this period, the effects are irreversible and have lifelong and intergenerational consequences on their future human capital and potential to succeed.
For the water and sanitation community the year 2009 marked a turning point in our understanding of the role that Water, Sanitation and Hygiene (WASH) has on child stunting. A provocative Lancet article (Humphrey 2009) put forth the hypothesis that a key cause of child stunting is asymptomatic gut infection caused by ingestion of fecal bacteria. Small children living in poor sanitary environments are especially at risk, through frequent mouthing of fingers and objects during exploratory play, playing in areas contaminated with human and animal feces and ingesting contaminated food and water (Ngure et al. 2013). Researchers now estimate that up to 43 percent of stunting may be due to these gut infections, known as environmental enteric dysfunction (EED) (Guerrant et al. 2013).
Just last week estimates were released suggesting that (Danaei et al. 2016). In a key departure from previous work, the researchers defined risk as the sanitation level of a community, rather than an individual. This is consistent with mounting evidence showing that a community’s coverage of sanitation is more important than any one household’s (Andres et al. 2013). Across different studies, data sets and outcomes the evidence consistently shows that a threshold of around 60–70 percent household usage within a community is needed before the health and nutrition benefits of sanitation begin to accrue. Studies that have focused on an individual’s toilet use as a predictor, rather than a community’s use, may have vastly underestimated the impacts (Hunter and Prüss-Ustün 2016).
As we advance our understanding of the ways in which a poor sanitary environment impacts growth in small children, we can better design water and sanitation interventions to target these pathways. While there is a role for multi-sectoral interventions, which can simultaneously target the underlying determinants of child undernutrition, such as food security, access to health services, and childcare practices — there are ways that the water sector can adapt its own approaches so that they are more nutrition-sensitive, and more impactful on nutrition.

A successful city is economically and culturally vibrant, healthy, safe, clean and attractive to business and tourism, and provides quality of life to its citizens. This vision is appealing but remains hard to realize as developing cities have to cope with changing demographics and climate with limited financial and human resources. The sustainable development goals have given a new impetus for cities to be inclusive, safe, resilient and sustainable (SDG11), ensure citizens’ health and wellbeing (SDG3) and secure access to sustainable water and sanitation services (SDG6).
World Toilet Day on November 19th is the opportunity to remind ourselves of a few facts and propose a set of guiding principles for a renewed and revitalized urban sanitation agenda.
In our previous blogs: Fecal Sludge Management: the invisible elephant in urban sanitation, 5 lessons to manage fecal sludge better, and A tale of two cities: how cities can improve fecal sludge management, we outlined the neglect of Fecal Sludge Management (FSM) and presented new tools for diagnosing urban sanitation challenges and how they can be used. Today, on World Cities Day, we are looking more deeply into a city — Lima, Peru, to shed light on how cities around the world can meet opportunities and address challenges of urbanization including providing improved sanitation for a rapidly growing number of urban residents.
Can a sustainable water sector be developed simultaneously with a country’s growth? Can the water sector continue to expand and achieve comprehensive coverage and financial sustainability goals to become a recognized global model for water sector management and performance? Can a country without a single sewer line in 1958 have 90 percent of its wastewater treated by 2012?
The answer is yes! The example is Korea.
Over the last few years, the international community has been busy establishing new indicators for the Sustainable Development Goals (SDGs), which officially replaced the Millennium Development Goals (MDGs) for the period 2015-2030. SDG #6: Ensure access to water and sanitation for all, seeks to reduce the incidence of malnutrition, communicable diseases, and inequities that are directly related to lack of access to improved sources of drinking water (affecting 663 million people worldwide) and sanitation (which 2.4 billion people still lack). This new goal implies a commitment by countries to monitor and report on their progress, similarly to what was done for the MDGs, but with much more detail.
Under the Millennium Development Goals (MDGs), countries were requested to report the coverage of water and sanitation, distinguishing between “improved” and “unimproved” coverage. The WHO/UNICEF Joint Monitoring Programme for Water Supply and Sanitation (JMP), established specific indicators for each, using definitions that could be captured with information from standard household surveys, which typically rely on self-reported questions on access to services collected from a nationally representative sample of households.
Niger is one of the world’s poorest countries (44.5% of poverty incidence in 2014). The country faces a number of challenges in meeting the national (PROSEHA, the National Program for sustainable development) and global targets to increase access to sanitation and potable water, particularly in rural areas where the access to water is 44.2% and 7% for sanitation (2015 Ministry of Water and Sanitation data).
Overcoming these challenges while satisfying increasing demands for better or expanded service, the government began investigating options that bring in the know-how of the private sector. This has led to a growing domestic private sector provision of services in Niger.
Fresh water touches every part of daily life—from drinking water and sanitation, to agriculture and energy production. Unfortunately, for nearly half of the world’s population, water scarcity is a growing issue with devastating impacts to our communities, economies and nature. In the past, countries have primarily turned to more supply-side infrastructure, including reservoirs and canals, as solutions to increasing water demands. But we can no longer build our way out of scarcity. We must find ways to do more with less, and impact investment can provide a catalyst for revolutionary changes in water management.
Water markets can be a powerful mechanism for alleviating water scarcity, restoring ecosystems and driving sustainable water management. Water markets are based upon water rights which can be bought and sold, enabling water to be transferred from one user to another. A well-managed water market provides economic flexibility, encourages water saving measures and brings a variety of stakeholders to the table to find balance between the water needs of people and nature.
The Nature Conservancy’s new report, “Water Share: Using water markets and impact investment to drive sustainability,” explores the potential for water markets and impact investment to serve as part of the solution to global water scarcity. Water markets, when paired with creative investment solutions including The Nature Conservancy’s concept of Water Sharing Investment Partnerships, can help provide a more water-secure future for cities, agriculture, industries and nature.
In previous blogs on Fecal Sludge Management (FSM), we outlined the lack of appropriate attention given to FSM as a formal urban sanitation solution and we presented new tools for diagnosing fecal sludge challenges. In this blog, we provide illustrations from Indonesia and Mozambique of the challenges and opportunities of using FSM.
Our last blog outlined the neglect of Fecal Sludge Management (FSM) and presented new tools for diagnosing FSM challenges and pointing the way to solutions.
In this blog, we’ll share some lessons learned from the city-specific case studies and analysis to highlight key areas which need to be addressed if the non-networked sanitation services on which so many citizens rely are to be effectively managed.

Small towns* typically have not been well served by national or regional water utilities. Decentralization has become increasingly widely adopted, but even if local governments at the small town level have the power to operate a water utility, they often lack the capital and skills to do so. In response, some local governments and public institutions concentrate improvements on upgrading public utilities’ operations or strengthening community based management. In other cases, they choose to bring in the private sector knowledge of how to get clean water and sanitation services to more people more efficiently, affordably or sustainably.
There are many ways in which the public sector can leverage its own resources through partnering with the private sector. For the domestic private sector to fully realize its potential at scale in the small town sub-sector, we found they need capable and enabled public institutions to structure the market and regulate private operators.
