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 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 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 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 Remarks at the United Nations Biodiversity Conference(World Bank, Washington, DC, 2021-10-12)World Bank Group President David Malpass discussed biodiversity and climate change being closely interlinked, with terrestrial and marine ecosystems serving as critically important carbon sinks. At the same time climate change acts as a direct driver of biodiversity and ecosystem services loss. The World Bank has financed biodiversity conservation around the world, including over 116 million hectares of Marine and Coastal Protected Areas, 10 million hectares of Terrestrial Protected Areas, and over 300 protected habitats, biological buffer zones and reserves. The COVID pandemic, biodiversity loss, climate change are all reminders of how connected we are. The recovery from this pandemic is an opportunity to put in place more effective policies, institutions, and resources to address biodiversity loss.Publication Media and Messages for Nutrition and Health(World Bank, Washington, DC, 2020-06)The Lao People’s Democratic Republic (Lao PDR) has experienced rapid and significant economic growth over the past decade. However, poor nutritional outcomes remain a concern. Rates of childhood undernutrition are particularly high in remote, rural, and upland areas. Media have the potential to play an important role in shaping health and nutrition–related behaviors and practices as well as in promoting sociocultural and economic development that might contribute to improved nutritional outcomes. This report presents the results of a media audit (MA) that was conducted to inform the development and production of mass media advocacy and communication strategies and materials with a focus on maternal and child health and nutrition that would reach the most people from the poorest communities in northern Lao PDR. Making more people aware of useful information, essential services and products and influencing them to use these effectively is the ultimate goal of mass media campaigns, and the MA measures the potential effectiveness of media efforts to reach this goal. The effectiveness of communication channels to deliver health and nutrition messages to target beneficiaries to ensure maximum reach and uptake can be viewed in terms of preferences, satisfaction, and trust. Overall, the four most accessed media channels for receiving information among communities in the study areas were village announcements, mobile phones, television, and out-of-home (OOH) media. Of the accessed media channels, the top three most preferred channels were village announcements (40 percent), television (26 percent), and mobile phones (19 percent). In terms of trust, village announcements were the most trusted source of information (64 percent), followed by mobile phones (14 percent) and television (11 percent). Hence of all the media channels, village announcements are the most preferred, have the most satisfied users, and are the most trusted source of information in study communities from four provinces in Lao PDR with some of the highest burden of childhood undernutrition.Publication South Asia Development Update, April 2024: Jobs for Resilience(Washington, DC: World Bank, 2024-04-02)South Asia is expected to continue to be the fastest-growing emerging market and developing economy (EMDE) region over the next two years. This is largely thanks to robust growth in India, but growth is also expected to pick up in most other South Asian economies. However, growth in the near-term is more reliant on the public sector than elsewhere, whereas private investment, in particular, continues to be weak. Efforts to rein in elevated debt, borrowing costs, and fiscal deficits may eventually weigh on growth and limit governments' ability to respond to increasingly frequent climate shocks. Yet, the provision of public goods is among the most effective strategies for climate adaptation. This is especially the case for households and farms, which tend to rely on shifting their efforts to non-agricultural jobs. These strategies are less effective forms of climate adaptation, in part because opportunities to move out of agriculture are limited by the region’s below-average employment ratios in the non-agricultural sector and for women. Because employment growth is falling short of working-age population growth, the region fails to fully capitalize on its demographic dividend. Vibrant, competitive firms are key to unlocking the demographic dividend, robust private investment, and workers’ ability to move out of agriculture. A range of policies could spur firm growth, including improved business climates and institutions, the removal of financial sector restrictions, and greater openness to trade and capital flows.Publication Economic Recovery(World Bank, Washington, DC, 2021-04-06)World Bank Group President David Malpass spoke about the world facing major challenges, including COVID, climate change, rising poverty and inequality and growing fragility and violence in many countries. He highlighted vaccines, working closely with Gavi, WHO, and UNICEF, the World Bank has conducted over one hundred capacity assessments, many even more before vaccines were available. The World Bank Group worked to achieve a debt service suspension initiative and increased transparency in debt contracts at developing countries. The World Bank Group is finalizing a new climate change action plan, which includes a big step up in financing, building on their record climate financing over the past two years. He noted big challenges to bring all together to achieve GRID: green, resilient, and inclusive development. Janet Yellen, U.S. Secretary of the Treasury, mentioned focusing on vulnerable people during the pandemic. Kristalina Georgieva, Managing Director of the International Monetary Fund, focused on giving everyone a fair shot during a sustainable recovery. All three commented on the importance of tackling climate change.Publication Making Procurement Work Better – An Evaluation of the World Bank’s Procurement System(Washington, DC: World Bank, 2024-12-06)This evaluation assesses the results, successes, and challenges of the World Bank 2016 procurement reform. Procurements acquire the works, goods, and services necessary to achieve the World Bank’s project development outcomes. The World Bank’s procurement processes must ensure that clients get the best value for every development dollar. In 2016, the World Bank reformed its procurement system for Investment Project Financing and launched a new procurement framework aimed at enhancing the Bank’s development effectiveness through better procurement. The reform sought to reduce procurement bottlenecks impeding project performance and modernize procurement systems. It emphasized cutting edge international good practice principles and was intended to be accompanied by procurement capacity strengthening to help client countries. This evaluation offers three recommendations to scale up reform implementation and enhance portfolio and project performance: (i) Improve change management support for the reform’s implementation. (ii) Strategically strengthen country-level procurement capacity. (iii) Consistently manage the full spectrum of procurement risks to maximize project success.
