Book Description
Water, sanitation and hygiene (WASH) investments are widely seen as essential for improving health in early childhood. However, the experimental literature on WASH interventions identifies inconsistent impacts on child health outcomes, with relatively robust impacts on diarrhea and other symptoms of infection, but weak and varying impacts on child nutrition. In contrast, observational research exploiting cross-sectional variation in water and sanitation access is much more sanguine, finding strong associations with diarrhea prevalence, mortality and stunting. In practice, both literatures suffer from significant methodological limitations. Experimental WASH evaluations are often subject to poor compliance, rural bias, and short duration of exposure, while cross-sectional observational evidence may be highly vulnerable to omitted variables bias. To overcome some of the limitations of both literatures, we construct a panel of 442 subnational regions in 59 countries with multiple Demographic Health Surveys. This large subnational panel is used to implement difference-in-difference regressions that allow us to examine whether longer term changes in water and sanitation at the subnational level predict improvements in child morbidity, mortality and nutrition. We find results that are partially consistent with both literatures. Improved water access is statistically insignificantly associated with most outcomes, although water piped into the dwelling predicts reductions in child stunting. Improvements in sanitation predict large reductions in diarrhea prevalence and child mortality, but are not associated with changes in stunting or wasting. We estimate that sanitation improvements can account for just under 10% of the decline in child mortality from 1990-2015.

Book Description
This publication, jointly prepared by WHO, the United Nations Children's Fund (UNICEF) and the United States Agency for International Development (USAID), summarizes the current evidence on the benefits of WASH (water, sanitation and hygiene) for improving nutrition outcomes and describes how WASH interventions can be integrated into nutrition programs. It provides practical suggestions, targeted at nutrition program managers and implementers, on both "what" WASH interventions should be included in nutrition programs and "how" to include them. It also seeks to help the WASH community to better understand their role, both as providers of technical expertise in WASH interventions and in prioritizing longer-term improvements to WASH infrastructure in areas where under-nutrition is a concern.

Book Description
The new 2030 Agenda for Sustainable Development includes water, sanitation, and hygiene (WASH) at its core. A dedicated Sustainable Development Goal (SDG 6) declares a commitment to "ensure availability and sustainable management of water and sanitation for all." Monitoring progress toward this goal will be challenging: direct measures of water and sanitation service quality and use are either expensive or elusive. However, reliance on household surveys poses limitations and likely overstated progress during the Millennium Development Goal period. In Innovations in WASH Impact Measures: Water and Sanitation Measurement Technologies and Practices to Inform the Sustainable Development Goals, we review the landscape of proven and emerging technologies, methods, and approaches that can support and improve on the WASH indicators proposed for SDG target 6.1, "by 2030, achieve universal and equitable access to safe and affordable drinking water for all," and target 6.2, "by 2030, achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations." Although some of these technologies and methods are readily available, other promising approaches require further field evaluation and cost reductions. Emergent technologies, methods, and data-sharing platforms are increasingly aligned with program impact monitoring. Improved monitoring of water and sanitation interventions may allow more cost-effective and measurable results. In many cases, technologies and methods allow more complete and impartial data in time to allow program improvements. Of the myriad monitoring and evaluation methods, each has its own advantages and limitations. Surveys, ethnographies, and direct observation give context to more continuous and objective electronic sensor data. Overall, combined methodologies can provide a more comprehensive and instructive depiction of WASH usage and help the international development community measure our progress toward reaching the SDG WASH goals.

Book Description
Since the 1960s, it has been known that poor water and sanitation causes diarrhea, which consequently compromises child growth and leads to undernutrition. Ample evidence shows that poor water and sanitation causes diarrhea, but there is a growing body of knowledge discussing the magnitude of the impact of diarrhea on undernutrition. A recent hypothesis by Humphrey (2009), for example, states that the predominant impact of contaminated water and poor sanitation on undernutrition is via tropical/environmental enteropathy (triggered by exposure to fecal matter) rather than mediated by diarrhea. This new hypothesis has generated much debate, especially in the South Asia region, on the contribution of water and sanitation to the South Asian Nutrition Enigma. The region is characterized by unusually high rates of child undernutrition relative to its income level, as well as a slow reduction in undernutrition. Practitioners have struggled to decipher the reasons behind this 'anomaly.' This report provides a systematic review of the evidence to date, both published and grey literature, on the relationship between water and sanitation and nutrition. We also survey the potential impact of improved water, sanitation, and hygiene (WASH) on undernutrition. This is the first report that undertakes a thorough review and discussion of WASH and nutrition in Bangladesh. The report is meant to serve two purposes. First, it synthesizes the results/evidence evolving on the pathway of WASH and undernutrition for use by practitioners working in the nutrition and water and sanitation sectors to stimulate technical discussions and effective collaboration among stakeholders. Second, this report serves as an advocacy tool, primarily for policy makers, to assist them in formulating a multisectoral approach to tackling the undernutrition problem.

Book Description
The evaluation of reproductive, maternal, newborn, and child health (RMNCH) by the Disease Control Priorities, Third Edition (DCP3) focuses on maternal conditions, childhood illness, and malnutrition. Specifically, the chapters address acute illness and undernutrition in children, principally under age 5. It also covers maternal mortality, morbidity, stillbirth, and influences to pregnancy and pre-pregnancy. Volume 3 focuses on developments since the publication of DCP2 and will also include the transition to older childhood, in particular, the overlap and commonality with the child development volume. The DCP3 evaluation of these conditions produced three key findings: 1. There is significant difficulty in measuring the burden of key conditions such as unintended pregnancy, unsafe abortion, nonsexually transmitted infections, infertility, and violence against women. 2. Investments in the continuum of care can have significant returns for improved and equitable access, health, poverty, and health systems. 3. There is a large difference in how RMNCH conditions affect different income groups; investments in RMNCH can lessen the disparity in terms of both health and financial risk.

Book Description
This open access book examines the interactions between India’s economic development, agricultural production, and nutrition through the lens of a “Food Systems Approach (FSA).” The Indian growth story is a paradoxical one. Despite economic progress over the past two decades, regional inequality, food insecurity and malnutrition problems persist. Simultaneously, recent trends in obesity along with micro-nutrient deficiency portend to a future public health crisis. This book explores various challenges and opportunities to achieve a nutrition-secure future through diversified production systems, improved health and hygiene environment and greater individual capability to access a balanced diet contributing to an increase in overall productivity. The authors bring together the latest data and scientific evidence from the country to map out the current state of food systems and nutrition outcomes. They place India within the context of other developing country experiences and highlight India’s status as an outlier in terms of the persistence of high levels of stunting while following global trends in obesity. This book discusses the policy and institutional interventions needed for promoting a nutrition-sensitive food system and the multi-sectoral strategies needed for simultaneously addressing the triple burden of malnutrition in India.

Book Description
In recent years, the world has seen unprecedented attention and political commitment to addressing malnutrition. Milestones such as the Scaling Up Nutrition (SUN) Movement, the Lancet Maternal and Child Nutrition Series, and the Second International Conference on Nutrition (ICN2) have marked the rapid rise of nutrition on the global policy and research agenda. These developments reverse years of relative neglect for nutrition. Undernutrition is a global challenge with huge social and economic costs. It kills millions of young children annually, stunts growth, erodes child development, reduces the amount of schooling children attain, and increases the likelihood of their being poor as adults, if they survive. Stunting persists through a lifetime and beyond—underweight mothers are more likely to give birth to underweight children, perpetuating undernutrition across generations. Undernutrition reduces global gross domestic product by US$1.4–$2.1 trillion a year—the size of the total economy of Africa south of the Sahara.
