Abstract
Hand washing with soap and water is a simple way to reduce the spread of disease. It doesnt require complicated technology, its usually affordable and even young children can do it. Yet many people dont wash their hands when they should: before touching food, after using the toilet or after cleaning a babys bottom. Campaigns to remind people to wash their hands arent always successful, even in places where both soap and water are easy to find. For health experts, the problem is puzzling. Bacteria, parasites and viruses can easily spread when people dont wash their hands, putting children at risk of potentially fatal diarrheal and respiratory infections. The World Bank is committed to ending poverty and giving everyone an equal chance in life, and promoting healthy habits can help make this happen. There are so many things that can conspire to keep people poor: bad education and few jobs usually come to mind first. But poor health can be as devastating, if not more so, to a persons ability to create, find and utilize opportunities. Illness drains finances and keeps people out of school and work. For young children, the results can be deadly: diarrhea is the second leading cause of death in children under the age of 5, and this despite the fact that its both preventable and treatable. As these studies underscore, changing behavior is difficult. The two studies taken together build on existing evidence showing that handwashing campaigns must move beyond traditional mass media into more personalized and intensive programs at the community and institutional level. Further research into how such approaches can be deployed on a large scale is needed, as is a better understanding of other environmental factors and fecaloral transmission pathways that can spread illnesses. This Evidence to Policy note was jointly produced by the World Bank Group, the Strategic Impact Evaluation Fund (SIEF), and the British governments Department for International Development.

Publication Kenya(Washington, DC, 2022-10)Before the COVID pandemic, more than half of children in low and middle-income countries suffered from learning poverty: they either were out of school or failed to learn to read with comprehension by age 10. At the same time, numerous studies have documented serious challenges related to the quality of education services, particularly for those serving poor students. In a country like Kenya, for example, teachers exhibit low levels of content and pedagogical knowledge. Previous research has shown that highly structured teaching guides could improve literacy, but scripted lessons are not without critics, who worry that teachers will not be able to adapt content to student’s needs. In places where teachers may be less prepared to tailor high quality lessons to their students, however, scripting may offer a way to standardize a minimum level of quality at scale.Publication India(World Bank, Washington, DC, 2021-07)In the first years of life, all children need healthy food, a clean environment, and stimulation to thrive and reach their full developmental potential. However, poverty prevents millions of young children in low- and middle-income countries from receiving adequate nutrition and stimulation. As a result, many disadvantaged children’s brain development lags behind that of their well-off peers, which can have lifelong consequences. Previous research from low-income settings has found that encouraging parents to play and interact more with their children can improve children’s brain development, with impacts that can last into adulthood. Delivering these parenting programs at scale and in a cost-effective manner, however, has been a challenge, in part because some of the most successful programs have been delivered through intensive and relatively costly home-based programs.Publication Rwanda(World Bank, Washington, DC, 2021-11)Children need a safe, nurturing, healthy, and stimulating environment to thrive and reach their full potential. But millions of children living in poverty don’t receive enough stimulation or good nutrition in their first years of life, and poverty also makes them more likely to experience neglect and violence in the home. Domestic violence, however, is rarely addressed in programs promoting young children’s development, which also typically focus on mothers, with little attention on fathers. Previous research suggests home-based parenting programs can lead to positive improvements in children’s brain development. Can these programs be adapted to address family violence as well Can these services be effectively delivered through government social safety net programs which often target poor, vulnerable familiesPublication Armenia(World Bank, Washington, DC, 2021-04)More people around the world are dying from noncommunicable diseases than ever before. These diseases, which include cancer, chronic respiratory diseases, diabetes, and heart disease, prematurely kill more than 15 million people between ages 30 and 69 each year. Many of these health conditions also make individuals more susceptible to severe forms of other diseases like Coronavirus disease 2019 (COVID-19). This study targeted adults between the ages of 35 and 68 in Armenia who had not been screened in the preceding year. The baseline data suggests this population was not economically secure: half of participants responded that their income was sufficient for basic family needs, such as food, clothing, and utilities, but not enough for big purchases like a car, while 35 percent responded that their income is sufficient for everyday food but not for clothes and other basic needs. More than half of those in the study were unemployed. This research finds that conditional incentives and personalized invitations can substantially increase screening for diabetes and hypertension for those who haven’t been recently screened. Further research may be needed to evaluate these interventions at scale.Publication Philippines(World Bank, Washington, DC, 2020-11)The World Bank’s Strategic Impact Evaluation Fund supported a randomized controlled trial from 2015-2018 to assess the extent to which subsidized microloans can enable households to build and use improved toilets. The loans, which carried zero interest, included toilet installation and were offered to poor beneficiaries who also received sanitation behavior change promotion as part of a social safety net program. The large financial subsidy led to modestly higher coverage of improved toilets, better toilet quality, and greater satisfaction, while the small subsidy did not improve access to improved sanitation. Among those who took out the subsidized loans, 59 percent already had improved toilets, which explains the limited effects on improved sanitation and open defecation. Overall, these findings suggest that subsidy programs hold promise, but need to be better targeted.

Publication Can Intense Exposure to Hand-Washing and Hygiene Information Campaigns Affect Children's Socio-Emotional Skills?(World Bank, Washington, DC, 2015-11)Hygiene information and practices play a critical role in preventing diseases, particularly among children. Hygiene behaviors practiced in the household have been linked to development outcomes such as socio-emotional skills. This paper exploits data from impact evaluation surveys of a hygiene information campaign conducted in Senegal, where the randomized design suffered from contamination between comparison groups. The variations in exposure and intensity to hygiene information campaigns captured in the surveys were used to understand contamination biases. Such variations were interacted with the presence of household communication assets to explore potential effects on children’s socio-emotional scores. In the presence of contamination biases, the study exploited the longitudinal sample of children in the surveys to reduce time-dependent biases. For robustness, statistical matching was applied between the impact evaluation surveys and Demographic and Health Surveys conducted in 2008 and 2011. Socio-emotional outcomes were the imputed into Demographic and Health surveys to expand sample sizes. By applying matching techniques and imputing outcomes into a larger sample, impacts were non-negligible. Double-difference estimates showed that children’s socio-emotional scores were higher when intervention status was interacted with the presence of communication assets within households. Without the presence of communication assets in the households the impacts were close to zero. Evaluating the effect of hygiene campaigns on children’s socio-emotional skills is challenging because of the biases from contamination that exist when information flows between comparison groups. Targeted hygiene information to the poorest households is relevant for reducing risks of recurrent infections and enables better conditions for socio-emotional development of children.Publication Four-Country Synthesis of the Enabling Environment for Hand Washing with Soap Endline Analysis(World Bank, Washington, DC, 2012-10)The Water and Sanitation Program (WSP)'s Global Scaling up Hand washing Project (HWWS) has ended its four-year implementation period (2007-2011). The project tested whether innovative approaches can generate large-scale and sustained increases in hand washing with soap at critical times among poor and vulnerable mothers and children in Peru, Senegal, Tanzania, and Vietnam. The assessments were repeated after three years of project implementation to assess progress in strengthening the enabling environment (EE) and to recommend additional steps to improve the EE as the projects wound down. The purpose of this report is to synthesize the main findings from the four end line EE assessment reports, including conclusions and lessons learned as well as recommended interventions and practices that can be used to strengthen the EE in the future. Aimed to gauge the robustness of the programmatic conditions for the continued scale-up and sustainability of program interventions as external funding for the projects end, the assessments were conducted from October 2010 through January 2011. The same basic instrument was used for the 2007 baseline EE assessments, with some modifications and additions made in 2010 based on program experience and learning.Publication Global Scaling up Hand Washing Project : Endline Assessment of the Enabling Environment in Peru(World Bank, Washington, DC, 2011-06)The Water and Sanitation Program (WSP) is in the final phase of the Global Scaling up Hand washing Project, implemented in Peru, Senegal, Tanzania, and Vietnam. In Peru, where the project is known as Iniciativa de Lavado de Manos, or the Hand washing Initiative (HWI), the specific target is to reach 5.1 million women and children under the age of 12 with hand washing messages by the end of the four-year implementation period (November 2010). The ultimate goal is to have 1.3 million people practicing improved hand washing behaviors. This report summarizes the end line assessment of the enabling environment (EE) for the Global Scaling up Hand washing Project in Peru. This assessment aimed to evaluate the robustness of the programmatic conditions for scale up and sustainability as the project's implementation phase was winding down. Research carried out from October 18 to November 5, 2010, followed a 2007 baseline EE assessment. The same instrument was used in both assessments, with some modifications and additions made in 2010 based on program experience and learning. An international consultant carried out the assessment.Publication Economic Assessment of Sanitation Interventions in Yunnan Province, People's Republic of China(Washington, DC, 2012-09)This study evaluates the costs and benefits of technical sanitation options and programs in Yunnan Province, China, as part of the Economics of Sanitation Initiative (ESI) conducted by the World Bank's Water and Sanitation Program in East Asia. As an underdeveloped province, Yunnan has achieved huge progress in sanitation improvement since the 1990s. Sanitation options evaluated in the study include the facilities to collect and convey human excreta, household wastewater treatment, and related hygiene practices. The benefits of sanitation evaluated include health, water quality, time to access sanitation facilities, external environment, reuse of human excreta, quality of life improvement, and other intangible benefits such as privacy, cleanliness and comfort. The costs of sanitation measured include investment costs and recurrent costs (operations and maintenance). The study compares the costs and benefits of alternative improved sanitation options over the expected life of each technology, to estimate efficiency of alternative sanitation options. For the study sanitation options in eight different sites throughout Yunnan Province were selected. Three rural sites include: a) villages in Luquan county s mountainous rural villages (R1); b) Dali Shangguan (R2) lakeside plain; and c) villages in Qiubei county (R3). Three urban sites represent: a) Kunming (U1); b) Dali (U2); and c) Qiubei (U3). Two peri-urban sites include: a) Kunyang town of Jinning County (PU1) and b) Dali Zhoucheng (PU2). The economic returns on all improved sanitation options are significant in all the sites evaluated, when compared with no access to basic sanitation.Publication Economic Assessment of Sanitation Interventions in Lao People's Democratic Republic(Washington, DC, 2013-08)Access to improved sanitation is a major concern in the Lao People s Democratic Republic. Only 63 percent of the population of the country had access to improved sanitation facilities in 2010. Sanitation conditions are worse in rural areas. This study aims to generate evidence on the costs and benefits of sanitation improvements Lao PDR.

Publication The Convergence of Sovereign Environmental, Social and Governance Ratings(World Bank, Washington, DC, 2021-03)This paper studies sovereign environmental, social, and governance (ESG) ratings from the qualitative and quantitative angles. First, it introduces the landscape for sovereign ESG ratings. Second, it provides a comparison with the history of credit ratings, factoring in that ESG ratings are in an early development stage. Third, the paper reviews different actors, key issues, including taxonomy, models and data from different providers. The paper provides a qualitative assessment of the convergence of ratings among providers by introducing a factor attribution method, that maps all providers' ratings into a common taxonomy defined by the United Nations-supported Principles for Responsible Investment (UNPRI). Then, a quantitative analysis of the convergence is performed by regressing the scores on variables from the World Bank sovereign ESG database. A noticeable contribution to the literature is a high level of explanatory power of these variables across all rating methodologies, with a R2 ranging between 0.78 and 0.98. An analysis of the importance of variables using a lasso regression exhibits the preponderance of the governance factor and the limited role of demographic shifts for all providers.Publication A Workbook on Planning for Urban Resilience in the Face of Disasters : Adapting Experiences from Vietnam’s Cities to Other Cities(World Bank, 2012-01-26)This workbook is intended to help policy makers in developing countries plan for a safer future in urban areas in the face of natural disasters and the consequences of climate change. It is based on the experiences of three cities in Vietnam, Can Tho, Dong Hoi, and Hanoi, that worked with international and local experts under World Bank supervision to develop local resilience action plans (LRAPs) in 2009-10. An LRAP is a detailed planning document that reflects local concerns and priorities based on the experiences of the past and projections for the future. It is not a wish list of projects that may never be completed because they are too costly or lack political support. Rather, it should be a realistic document that describes and establishes priorities for specific steps that can be undertaken in the near term to adapt to both climate related and other hazards. Regardless of their size, location, political orientation, or technical capacity, other cities can learn from the experiences of these pilot cities to develop their own LRAPs. The purpose of this workbook is to adapt the initial experiences of Can Tho, Dong Hoi, and Hanoi to benefit the national government and other communities in Vietnam and beyond. Indeed, the process described in this workbook was later adopted in the cities of Iloilo, the Philippines; Ningbo, China; and Yogyakarta, Indonesia, and the concluding chapter of this workbook draws on some of the lessons learned in these cities. However, the workbook, while generalizable to other contexts, largely reflects the Vietnamese experience.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.Publication Growth Spillover Effects and Regional Development Patterns : The Case of Chinese Provinces(World Bank, Washington, DC, 2005-06)The author discusses regional development patterns in China and examines effective ways of using development aid to attain regional balanced growth through optimizing growth spillover effects. Based on provincial panel data from 1978-99 she constructs an indicator "neighborhood performance" to measure the geographic spillover effects of aggregate growth from and to different provinces according to their relative richness and geographic position. Analysis of a Solow-type growth model suggests that positive spillover effects dominate negative shadow effects at the national level as well as the regional level, and some coastal provinces provide growth pull and growth push forces for their neighbors and serve as locomotives. The results show that the rapid takeoff of the coastal provinces has the largest spillover effects on the Chinese economy, but at the expense of a widening regional gap. A policy of encouraging the growth of the non-coastal regional hubs would have strong forward and backward linkages with the inland and western regions and thus reduce the regional development gap without sacrificing much aggregate growth. The author offers support for the policy of developing inland hubs, and argues that directing development aid to Hubei and Sichuan would optimize the growth spillover impacts on inland regions.Publication Credit Worthy(World Bank, Washington, DC, 2022-01)The increasing role of the financial sector in the move toward a more sustainable economic model continues apace. The Coronavirus (COVID-19) shock shone a light on the need for all society to correct course, and the financial sector is responding. The pace of environmental, social, and governance (ESG) integration into investment decisions, which has become the prevalent form of sustainable finance, continues to accelerate. These developments reflect changing societal perspectives that challenge the traditionally ingrained investment approaches that have evolved over many decades. Against this backdrop, various financial sector stakeholders continue to evaluate how their role, products, and tools should adapt to this evolving landscape. This paper focuses on sovereign credit ratings and empirically assesses how broad sovereign ESG factors as well as the ESG factors specific to a country’s national wealth and management of risks and opportunities related to so-called stranded assets like fossil fuel resources are manifested in sovereign credit rating assessments.
