Reforming urban sanitation under decentralization: Cross‐country learning for Kenya and beyond

Nathaniel Mason, Charles O. Oyaya, Julia Boulenouar

Abstract Motivation Across the Global South, unclear institutional frameworks undermine progress in improving services. Often, ongoing decentralization reforms reduce clarity further. Policy professionals working on institutional reform lack comparative models. Purpose To identify key challenges for the institutional arrangements for urban sanitation in decentralizing contexts, in Kenya and elsewhere, and to propose possible responses. Approach and methods We use key informant interviews and literature review in a problem‐driven analysis, drawing from three comparative case studies: South Africa, Indonesia and Tamil Nadu State. The analysis builds upon research on institutional effectiveness—co‐operation, collaboration and co‐ordination—rooted in game theory and elaborated in the 2017 World Development Report. Findings Three key problems in Kenya are identified: overlaps and competition around sector leadership at national and devolved levels; weak incentives for county governments to commit policy attention and finance, despite devolution; and limited regulatory oversight. Policy implications We identify a range of options for urban sanitation policy‐makers: (a) to engage non‐sectoral authorities in co‐ordinating multi‐sectoral issues across all levels of government; (b) to encourage political commitment to pro‐poor sanitation services at decentralized levels; and (c) to use incentive‐based and risk‐based approaches to regulate decentralized entities and strengthen local capacity for monitoring and enforcement.

Drinking-water management in Canadian provinces and territories: a review and comparison of management approaches for ensuring safe drinking water

Ty Bereskie, Ianis Delpla, Manuel J. RodrĂ­guez, Rehan Sadiq

Abstract Drinking-water management systems (DWMSs) represent the primary means for preventative management of a drinking-water supply and are defined as a system of policies, procedures and administrative/behavioral controls designed to ensure safe drinking water from source to tap. With influence and inspiration ranging from safe food handling to industrial quality management, DWMSs can take, and have taken, many different forms throughout the world. This variability is especially true in Canada, a country with a decentralized governance structure, where provincial and territorial governments are mostly autonomous in regard to drinking-water governance and management. While this has resulted in comprehensive DWMSs in provinces such as Ontario, less-proactive provinces and territories have fallen behind and may be exposing consumers to under-protected and vulnerable drinking-water supplies. This paper includes a review and comparison of the existing Canadian national, provincial and territorial approaches to drinking-water management, the World Health Organization Water Safety Plan Recommendations, national DWMSs from Australia and New Zealand, and also includes widely applied, generic quality management systems. This information is then used to gauge the comprehensiveness of DWMSs in Canada and highlight potential management gaps and policy recommendations for the development of new, or improving existing, DWMSs.

Understanding pathways to better nutrition at district level: Lessons from Uganda

Edgar Agaba, Sanjiban Ghosh, Jeffrey K. Griffiths

For countries looking to implement multisectoral nutrition plans, it is critical to understand what works and how programs should be delivered and scaled-up in each context. Programs can learn from each other on how to adapt to new information, evidence and events related to scaling-up and district stakeholders can play important roles in implementation of this multisectoral plan. As part of "Pathways-to-Better Nutrition" (PBN) case study conducted by USAID/SPRING Project, this research set out to explore district leaders' perceptions of the nutrition situation, programs and opportunities for integration. Qualitative data were collected through key-informant interviews and focus group discussions. Thirty-five district and local leaders belonging to district and sub-county multisectoral nutrition committees in Kisoro and Lira were interviewed. Grounded Theory Approach was used to identify themes for coding and key domains included: learning, adoption and evidence of scale-up; adoption of innovations/interventions to local context, financing of nutrition-sensitive activities and long-term planning. Additionally, quantitative data collected by Feed the Future Innovation Lab for Nutrition were analyzed in each of the districts to provide nutrition snapshots. Malnutrition in the study districts was worse than the national average for stunting, anemia and women's underweight. The majority (91%) of respondents were not familiar with these nutrition statistics. Both study areas have formed nutrition multisectoral working groups (District Nutrition Coordinating Committees) and have developed management structures to implement interventions. Government stakeholders from every nutrition-sensitive sector referred to the lack of clear government programs that support nutrition directly in local policy environment. Key agricultural-related programs are focusing on wealth creation, value-addition or increasing agricultural productivity without nutrition lens (not "nutrition sensitive"). Nutrition is not on the 'list' of key priorities of district health departments unlike HIV/AIDS, malaria or sexual reproductive health. About 69% respondents believe they lack operational capacities and soft-power skills to design, implement and manage nutrition interventions such as leveraging of resources and being able to convey evidence. The understanding of "Scaling-up Nutrition" also differed by respondent, and this has resulted in different goals and measurements. Challenges related to nutrition financing were also noted, including fiscal decentralization, use of Output-Based Financing mechanisms, limited flexibility to re-allocate funds for nutrition, and lack of standard reporting procedures or implementation strategy. Efforts to address malnutrition need to be multisectoral, coupled with increased coordination of different sectors and ministries for sustained impact on nutrition outcomes.

Optimizing the Multisectoral Nutrition Policy Cycle

Sascha Lamstein, Amanda Pomeroy–Stevens, Patrick Webb, Eileen Kennedy

Based on the data collected in Uganda, Nepal, and Ethiopia, the papers included in this supplement fill a critical gap in evidence regarding multisectoral National Nutrition Action Plans. The studies offer new data and new thinking on how and why governance, effective financial decentralization, and improved accountability all matter for nutrition actions in low-income countries. This introductory paper offers an overview of the current state of evidence and thinking on the multisectoral nutrition policy cycle, including how governance and financing support that process. It also explores the benefits of applying a systems lens to understand the dynamic, enabling processes of the policy cycle-from research to knowledge and ultimately action-and to provide more dynamic and accurate information for nutrition advocacy and evidence-based decision-making. It concludes with key findings from the 5 country-level studies included. Several important themes emerge: the egregious gap in human resources needed for effective nutrition actions in most low-income settings, the value of research on bottlenecks and successes, and the need for routine monitoring of national policies and plans to measure their effectiveness in achieving both their own stated goals and global sustainable development goals. Reviewing these studies together provides a path forward in building stronger, evidence-based multisectoral nutrition policies and supporting implementation of the nutrition activities included within them.

A new approach to implementing decentralized wastewater treatment concepts

Manfred van Afferden, Jaime Cardona, Mi-Yong Lee, Ali Subah · 5 authors

Planners and decision-makers in the wastewater sector are often confronted with the problem of identifying adequate development strategies and most suitable finance schemes for decentralized wastewater infrastructure. This paper research has focused on providing an approach in support of such decision-making. It is based on basic principles that stand for an integrated perspective towards sustainable wastewater management. We operationalize these principles by means of a geographic information system (GIS)-based approach 'Assessment of Local Lowest-Cost Wastewater Solutions'--ALLOWS. The main product of ALLOWS is the identification of cost-effective local wastewater management solutions for any given demographic and physical context. By using universally available input data the tool allows decision-makers to compare different wastewater solutions for any given wastewater situation. This paper introduces the ALLOWS-GIS tool. Its application and functionality are illustrated by assessing different wastewater solutions for two neighboring communities in rural Jordan.

Learning from implementation of the sanitation and hygiene master plan in Nepal

Anup Adhikari, Bhagwan Aryal, Namaste L. Shrestha

This briefing paper has been prepared based on the basis of field level experiences. It highlights the emerging decentralized leadership in the WASH sector in light of the Master Plan and ODF movement in Nepal. The Master Plan has introduced innovative institutional arrangement of inclusive WASH Coordination Committees to lead ODF movement. These committees leadership of such committees hashave come up with several innovations in planning, financing, implementation and monitoring, and promoting inclusive and participatory governance process in sanitation development. Nepal's sanitation campaign has visibly scaled up ODF status despite some shortcomings. Mobilization of local resources is possible through local leadership, sustainability requires equal emphasis on behavioural and facility aspects and advocacy for health benefits of the improved sanitation are the prime drivers for changes. Similarly, cross-learning are vital for innovations in the sector and integration of sanitation with other development sector activities enhances synergy. The post-ODF intervention is leading the sanitation sector towards livelihood promotion and social wellbeing aspect too.

Global Efforts to Address Severe Acute Malnutrition

Ricardo Uauy, Jehan‐François Desjeux, Tahmeed Ahmed, Muttaquina Hossain · 8 authors

Childhood malnutrition encompasses a plethora of nutritional disorders that include stunting, underweight, wasting, severe acute malnutrition (SAM), and micronutrient deficiency disorders. Overweight and obesity, at the other end of the nutritional spectrum, are also manifestations of childhood malnutrition. Nearly 24 million children (younger than 5 years) worldwide experience SAM. The vast majority is located in Africa and Asia (8 million are in India alone). A child with SAM is 10 times more likely to die than a well-nourished child. SAM is one of the top 3 nutrition-related causes of death in children younger than 5 years. Estimates of deaths directly attributable to SAM varied from 0.5 to 2 million annually. Moderate and severe child malnutrition account for 40% to 50% of all deaths in children younger than 5 years. If the United Nations Millennium Development Goals (http://www.un.org/millenniumgoals) of reducing children malnutrition and mortality by 50% by 2015 are to be met, SAM needs to be prevented and controlled effectively. UN SYSTEM (UNICEF-WHO-WFP) ACTIVITIES IN PREVENTION AND TREATMENT OF SAM Support countries with high levels of SAM to scale up coverage for treatment through community-based management of acute malnutrition (CMAM) Preventing acute malnutrition in children and women through increasing coverage of high-effect interventions (eg, micronutrients) Inpatient treatment is reserved for the smaller group that requires close medical monitoring and therapies that are exclusive to medical facilities: parenteral hydration, treatment of hypotension, shock, metabolic alterations (hypoglycemia, hypothermia), or severe infections Integrated management of PEM considers both inpatient and outpatient treatment of SAM; whenever possible outpatient treatment should be used based on the following advantages: Minimizes effect on family and requires limited health services support Simpler treatment: no food preparation is required, can be eaten directly Broad coverage: eliminates primary barriers to “scaling up” (need for doctors and health facilities) Active case finding relies on community outreach The support for using community-based treatment is also based on equal or lower mortality rates and reduced cost (US$∌450–∌$130/child).Policy formulation at country level is progressing rapidly; 95% countries have national guidelines/protocols for acute malnutrition as evidenced by: Visible policy documents and joint statements Increasing coverage and scaling-up of programs: 55 countries implementing CMAM; an additional 7 countries are in the planning stages. Integration of CMAM with other primary health progress in at least 50% to integrate activities: integrated management of childhood illness, infant and young child feeding, human immunodeficiency virus/acquired immune deficiency syndrome Increasing adherence to a comprehensive integrated approach into health system Global guidelines and training resources are available including incorporation of infant feeding orientation into trainings.Challenges encountered in the implementation of the CMAM include Weakness in existing intersectoral linkages; stronger links with food security and other sectors are required in support of long-term solutions and prevent short-term emergencies Unpredictable funding; most resources still derived from humanitarian response for acute emergencies averting multiyear planning Difficulties in setting up long-term supply plans to ensure that ready to use therapeutic food (RUTF) needs are met and buffer stocks are in place. Geographical distance of manufacturers from the final beneficiaries is a problem; however, proliferation of unreliable local suppliers with poor quality control systems is not the answer. UN SYSTEM ACTIVITIES IN PREVENTION AND TREATMENT OF SAM The WHO Electronic Library of Evidence for Nutrition Actions (eLENA) has been released (www.who.int/elena). This updated version of the site includes new nutrition intervention topics such as food supplementation for children with moderate acute malnutrition, vitamin D supplementation in infants, multiple micronutrient supplementation in pregnant women, and community-based feeding for the promotion of child growth. Updates of the eLENA site have been launched and include translations into the 5 official WHO languages. The Spanish site was launched during the World Health Assembly in May 2012 (www.who.int/elena/es). Updated guidelines on the integrated management of SAM in children are expected to be released in the upcoming edition of eLENA. The Global Database on the Implementation of Nutrition Action is a complementary Web-based tool in which governments and organizations can upload and share information on their nutrition activities. The Global Database on the Implementation of Nutrition Action will have a user-friendly interface with interactive maps, lists, and fact sheets that show what is being done where, when, with whom, why, and how to scale up and improve nutrition. Users are invited to continue to upload nutrition action information via the online form at www.who.int/nutrition/gina. CHALLENGES FOR HEALTH PROFESSIONALS CONCERNED WITH GASTROINTESTINAL DISEASES AND NUTRITION IN ADDRESSING SAM Clearly, there is a need for all concerned parties to join forces; pediatricians and especially those with interest in gastrointestinal (GI) diseases and nutrition have an important role to play. Key challenges ahead and potential approaches in addressing them are summarized in the next section. Lack of political commitment: Nutrition is often a low priority on the political agenda resulting in limited funding or in some cases no secure budget allocation being made. SAM in many cases is not even recognized as a health problem (not included in surveillance systems). Health professionals should also be strong in advocacy efforts and lead the battle against SAM calling the attention of all concerned parties, not only on moral grounds but also as a key investment for national development. The implementation of known solutions requires a strong delivery system, such as infant and young child feeding. Thus, a well-supported health care service with broad coverage is fundamental, particularly in hard-to-reach areas and for population groups living in poverty or emergency conditions. Resistance of some governments to use imported ingredients, that is, RUTF or other costly supplies, limits implementation of CMAM programs in some areas of the world. The concerns are commonly based on sustainability and having to depend on imported commodities. These can be circumvented by using local ingredients and/or local blending of ingredients depending on circumstances. The appropriate design and effective implementation of CMAM requires local capacity to design, implement, and evaluate programs. Limited local capabilities impede progress in controlling and preventing malnutrition in many countries. The effectiveness of CMAM program requires local institutional capacity to ensure the delivery of a comprehensive package of services in emergencies (CMAM and micronutrients); in addition, information needs to be collected and reported to assess cost-effectiveness of the interventions. Successful sustained control of SAM requires intersectoral linkages beyond health; at the very least, they should include agriculture (food and nutrition security), water and sanitation, women's and children rights, community participation and empowerment. Creating sustainable livelihoods allows communities to meet their basic needs. Only then can governments be held accountable and responsible in addressing the social and economic determinants of SAM. Sustained funding for activities, programs, development of institutional and human capacity is fundamental to avert acute emergencies. Predictable medium- and long-term funding and multiyear planning are essential to prevent malnutrition in all its forms and avert the consequences on human and social development. Long-term supply to ensure that raw materials to produce RUTF are met and buffer stocks are in place and available to cover local needs. This requires appropriate quality control and distribution systems. Systematic collection of local, regional, and national data collection and information systems should be in place to guide CMAM activities, map SAM, and focus efforts on most-affected areas. Information flow from field to national level should be established; consistent use of WHO reference growth standards should be used within and between countries, defining common performance indicators for regional- and country-level reports. This report is a short account of present efforts in addressing SAM; what we do or fail to accomplish in the next few years will have major significance if we are to achieve the millennium development goals 1 and 4. Halving hunger by 2015 most likely will not be achieved on a global basis; however, with appropriate support, this may be achieved by many countries in Africa and southeast Asia. Similarly, reducing by two-thirds the mortality of children younger than 5 years unless we make this a global priority for action and do not leave this to action by local governments that may or may not see this as a top priority. It is time that we consider child health and well-being a global priority subject to commitments by global governance; sooner or later we must face that “children's needs cannot be postponed.” We must act now to secure their basic needs—the future of humanity is at stake. All JPGN readers are concerned with malnutrition in children because most diseases of the GI tract have a negative effect on nutrition. Because they are common all over the world, essentially as a consequence of infection, they represent a major cause of malnutrition. Malnutrition, A Risk to All Children and Humanity Nutrition is essential for all life to be perpetuated through reproduction. Childhood is the period in which growth and psychosocial development are supported by use of food through metabolic processes genetically determined. Malnutrition is a generic term that covers the results of any deviation that impairs growth and development. It may be so severe that it may remove the life of the child. Most often the child recovers after proper treatment, but in too many children, it will last for years. Many girls reach reproductive age in poor nutritional condition. The millions of children born to malnourished women are more likely to face cognitive impairments, short stature, lower resistance to infections, and a higher risk of diseases throughout their lives, thus perpetuating the cycle of malnutrition. Select Realistic Target At the global scale, the most prevalent situation is deficit rather than abundance in food availability or food use or both, for example, as a consequence of GI disorder, infectious disease, or low birth weight (LBW). According to UNICEF, 1 in 4 children in the developing world are underweight. Because pediatricians are facing such a disaster, it is difficult to imagine what can be done to solve it; however, by targeting specific population, it may be possible to envisage proper treatment. First, it is important to define the different states of malnutrition. Malnutrition may be the results of general or selective food deprivation, essentially iron, iodine, zinc, and vitamin A. The most common clinical conditions are underweight, stunting, and wasting. All of these conditions occur in different context that need to be analyzed. Second, it is important to identify the regions of the world that need context-specific approaches. More than 10 million children die each year, most from preventable causes and almost all in poor countries. Six countries account for 50% of worldwide deaths in children younger than 5 years, and 42 countries for 90%. The causes of death differ substantially from one country to another. A better understanding of child health epidemiology could contribute to more effective approaches to saving children's lives (1). Severe Acute Malnutrition SAM is defined by an extremely low weight for height, by visible severe wasting, or by the presence of nutritional edema. Until the end of the 20th century, the median under-5 case-fatality rate for SAM typically ranges from 30% to 50%. It was reduced substantially (typically <5%) when physiological and metabolic changes were taken into account and a standardized protocol was initiated (2). The use of F100 as a milk powder reconstituted with water to obtain 100 kcal/100 mL was effective but its use was limited to medical structures. The RUTF was a major step in overcoming the limitation of F100 (3–5). In 1997, AndrĂ© Briend, who was the initiator of such treatment, conducted the first clinical trial in Tchad as a proof of concept. In 2005, in Niger, MĂ©decins Sans FrontiĂšres treated at home 60,000 children with a success rate of 90%. Such a therapeutic approach is expected to save millions of children. Linear Programming One approach to prevent malnutrition and maintain healthy nutritional status is to use locally available food. However, many limits need to be taken into account, including food availability, composition, and cost, which must cover the nutrient recommendations for that population. Historically, such an approach was at on trial and The of nutrition has been with a tool The is The more a child a for example, the more or and such a is The for and and cost of the This is what can solve an program was then more user-friendly programs were for example, In a program was being and should be released more pediatricians and to proper recommendations that are as food rather than Such an approach could be used in many different in both and developing Childhood Malnutrition in Asia defined as the reference is the most common of childhood malnutrition and malnutrition.

SISAR: a sustainable management model for small rural decentralized water and wastewater systems in developing countries

Alejandro Meleg

Investments for basic rural sanitation programs should not only focus on the construction of new installations, but also on the necessity of implementing proper management models that guarantee the operational and financial sustainability of the investments. The integrated rural sanitation system (SISAR) is based on the idea of creating a confederation of local user groups which come together on a regional basis, and through an adequate institutional setup, are responsible for managing SISAR and assuring the adequate provision of water supply and in some cases, wastewater services. Financial sustainability is achieved by the implementation of tariffs for water consumption and provision of wastewater services generating revenue which is redistributed among all systems in order to cover all operational, maintenance and administration costs. Important stakeholders in the model include, besides the users, local and state government and international financing institutions responsible for financing the investments in the construction of rural water supply and wastewater systems. This document focuses on the experience and results achieved by SISAR in the Brazilian state of CearĂĄ. In 2001 eight SISARs began providing improved water supply services in 66 settlements. Today, more than 560 settlements (more than 330,000 inhabitants) are supplied by SISARs.

The Nonspecific Effects of Vaccines and the Expanded Program on Immunization

Frank Shann

(See the article by Aaby et al, on pages 245–52.) There is now clear evidence that the simplistic conventional model of immunization is invalid [1]. We can no longer assume that a vaccine acts independently of other vaccines, or that it influences only infections caused by the target disease. Strong evidence from randomized trials suggests that bacillus Calmette-GuĂ©rin vaccine (BCG) reduces mortality from infections other than tuberculosis and that measles vaccine reduces mortality from infections other than measles [1–4]. However, there is worrying evidence that whole-cell diphtheria-tetanus-pertussis vaccine (DTP) may increase mortality from infections other than diphtheria, tetanus, or pertussis in high-mortality areas [1, 3–8]. These nonspecific effects of BCG, measles vaccine, and DTP are generally stronger in girls, appear to be maximal in the first 6 months after immunization, and are largely determined by the most recent vaccine administered [1]. Randomized trials show that measles vaccine has strong nonspecific effects. Providing it is not given after vitamin A or followed by DTP, measles vaccine reduces mortality from diseases other than measles by 45% (95% confidence interval [CI], 14%–65%) when given at 4.5 months of age [9], and by 47% (95% CI, 23%–63%) when given to girls at 9 to 10 months of age [1]. In this issue of the Journal, Aaby et al present further evidence, from Guinea-Bissau, that BCG has potent nonspecific effects on mortality [4]. Low-birth-weight neonates were randomized to receive BCG at birth or via the routine immunization program at an older age (median, 7.7 weeks). The biological effects of BCG are shown by the outcome during the first 4 weeks after randomization, before children in either group had been given DTP and when few children in the control group had received BCG. In this period, BCG reduced mortality by 45% (95% CI, 11%–66%); there were fewer deaths from sepsis and acute respiratory infection, and no deaths from tuberculosis (which is a rare cause of death at this age). This spectacular reduction in mortality is consistent with the results of 6 controlled trials performed in 45,662 children in the United States and the United Kingdom in the 1940s and 1950s, in which BCG reduced mortality from causes other than tuberculosis by 25% (95% CI, 6%–41%) [1, 2]. Although BCG reduced mortality in the first 4 weeks of life in the trial in Guinea-Bissau, investigators observed no difference in mortality after that age [4]. This is not surprising, because by 2 months of age 58% of the controls had received BCG and over 60% of children in both groups had received DTP. Consequently, BCG did not significantly reduce mortality in the first 12 months of life, the observed reduction being 17% (95% CI, −8% to 37%). This was the primary endpoint of the trial, which was underpowered because infant mortality was 101 deaths per 1000 live births, rather than 250 deaths per 1000 live births as predicted when the trial was designed. A lower-than-expected mortality often occurs when trial participants in a high-mortality area are offered free treatment, as in this study. This illustrates how difficult it is to do randomized trials in high-mortality areas, where we most need to obtain information about how to lower mortality. A worrying finding in this trial was that children who had received DTP by 2 months of age had an increased mortality between 2 and 6 months of age: Mortality was increased 4.3-fold (95% CI, 1.5–12.2-fold) in the BCG-at-birth group and 1.7-fold (95% CI, .7–4.0-fold) in the control group [4]. DTP was observed to have similar effects in a randomized trial of revaccination with BCG at 19 months of age in Guinea-Bissau [3]. In that trial, 60% of the participants had not received their last dose of DTP (DTP4) at the time of enrollment, and many of these children were given DTP4 after entering the study. Children who received BCG had a lower mortality than controls if they had received DTP4 before enrollment (hazard ratio, .36; 95% CI, .13–.99) but a higher mortality if they had not received DTP4 before enrollment (hazard ratio, 1.78; 95% CI, 1.04–3.04); the difference was highly significant (P = .006). Mortality was 0.36 deaths per 100 person-years if DTP4 had been given before BCG revaccination, 1.02 deaths per 100 person-years in controls who were not revaccinated with BCG (mortality was not affected by DTP4 status at enrollment), and 1.83 deaths per 100 person-years if DTP4 had not been given before BCG revaccination [3, 10]. These 2 studies suggest that BCG lowers mortality if it is given alone or after DTP, but that mortality may be increased if DTP is given after BCG as recommended in the schedule for the Expanded Program on Immunization (EPI) [3, 4]. The administration of DTP after BCG was not randomized in these studies, so the observed increase in mortality with DTP may have been caused by bias. However, this seems unlikely. In the trial of BCG in low-birth-weight babies [4], the infants who had received DTP by 2 months of age (and had increased mortality) were larger babies who would be expected to have a lower mortality in the absence of a nonspecific effect of DTP. In the trial of BCG revaccination at 19 months of age [3], mortality in the control group (no additional BCG) was not influenced by DTP4 status at the time of randomization, suggesting that this was not an independent risk factor. Even in unimmunized communities, diphtheria, tetanus, and pertussis cause far fewer deaths than pneumonia, sepsis, and diarrhea [11]; despite reducing mortality from diphtheria, tetanus, and pertussis, DTP will, therefore, increase total mortality if it causes even a small increase in mortality from pneumonia, sepsis, and diarrhea in high-mortality areas [12]. When DTP was first introduced into Guinea-Bissau, despite the absence of herd immunity, mortality was 5.1 deaths per 100 person-years among children who did not receive DTP but 11.3 deaths per 100 person-years among children who did receive DTP (risk ratio, 2.03; 95% CI, 1.17–3.52) [7]. I know of no other study of the introduction of DTP in a high-mortality area with sufficient power to test the effect on total mortality. No randomized trial has demonstrated that it is safe to give DTP to young infants in high-mortality areas, and there is now worrying evidence that DTP may increase mortality under these circumstances—especially when it is given after BCG as recommended in the EPI schedule [1, 3–8]. In 2002, 2003, and 2004, the WHO Global Advisory Committee on Vaccine Safety (GACVS) concluded that the evidence did not support an increased risk of mortality after DTP immunization [13]. However, the onus of proof is surely the reverse of this—we need clear evidence that a vaccine is safe when it is given routinely to all infants in high-mortality areas. In addition, the Committee based its conclusion on observational studies, all of which had one or more serious methodological problems [1, 5, 14–16]. First, any observational study (with nonrandom allocation of vaccines) may induce a spurious association between vaccination and survival [16]. Second, vaccination was often withheld in sick children, which causes selection bias in favor of DTP [5]. Third, many of the studies classified dead children as unvaccinated if there was no evidence they had been immunized; as some of these children will have been vaccinated, this causes survival bias in favor of DTP [1, 5, 14–16]. Fourth, most of the studies did not test the effect of the most recent vaccine received by each child over time: the first dose of DTP has different effects when given before, with, or after BCG [4, 5]; the last dose of DTP has different effects given before, with, or after measles vaccine [5, 6]; and the effects differ by sex [1]. Fifth, many children were given BCG at the same time as DTP, rather than at birth (6 weeks before DTP) as specified in the EPI schedule [5]. In 2008, GACVS finally endorsed the view that evidence for the safety of DTP is “unlikely to be obtained from observational studies” [17]. Given the very large number of lives at stake, it is disappointing that it took the Committee so long to decide that observational studies are unlikely to provide adequate evidence that it is safe to give DTP to infants who have been vaccinated with BCG at birth, and even more disappointing that international agencies have not funded randomized trials to test the effect of DTP on all-cause mortality in children in high-mortality areas [5, 18]. We could obtain this information while still immunizing against diphtheria, tetanus, and pertussis if we randomized children to receive the primary series of DTP at different ages, or to receive a booster dose of DTP at different ages [18, 19]. The current EPI schedule is BCG-polio at birth; DTP-polio at 6, 10, and 14 weeks; and measles vaccine at 9 months–but tuberculosis, polio, diphtheria, tetanus, pertussis, and measles are not the main causes of death in children, even in unimmunized communities [11]. The main reason that the EPI program has been beneficial may not be because it protects against these infections, but because the nonspecific effects of BCG and measles vaccines reduce the very large number of deaths from pneumonia, sepsis, and diarrhea. It is exciting that we may be able to save several million more lives each year just by making better use of the current EPI vaccines in an improved schedule—we urgently need randomized trials of the effects of the EPI vaccines on total mortality to help us design the optimal schedule [5, 18].

Integration of capacity factors analysis risk methodology and Ostrom's social ecological system assessment framework to assess and improve domestic water infrastructure in Nalgonda District, Andhra Pradesh, India

Siddhartha Pailla, Garrick Louis

Over the past 50 years, both financing and socio-economic considerations in South India have shifted heavily towards improving urban infrastructure, causing rural services to be left behind. A recent report released by WHO and UNICEF states that over 884 million people, 84% of whom live in rural areas, use “unimproved water sources” for domestic purposes. This paper considers the case study of Nalgonda, a district to the east of Hyderabad, India. Nalgonda struggles with three main issues concerning domestic water: high fluoride levels in groundwater have caused thousands of cases of dental and skeletal fluorosis; second, over two-thirds of Nalgonda does not meet the WHO-requirement of 40 liters per capita daily of domestic water supply; third, poor management and maintenance have increased the risk of failure of existing water infrastructure. The state has been pursuing these issues in conjunction with a multi-district irrigation project that taps the regional Nagarjuna Sagar Dam. Centralized water supply, treatment, and distribution services are appropriate for high population density areas; however, geographical expanse and sparse populations lead to onerous access to improved water sources and inhibit the success of a similar centralized framework in rural areas. This is compounded by a lack of ownership at the habitation and socio-cultural levels. Further, the current water network and its problems - including inconsistent service, corruption, and general distrust of the treated Sagar water - have emboldened wealthier citizens to build private, unregulated groundwater defluoridation plants and commercialize small-scale water businesses. Inequitable services and uncertainty of shared water resources have caused a “tragedy of the commons,” leading to growing disparity and a severely receding water table. This research proposes the Louis-Ostrom Comprehensive Capacity Assessment (LOCCA) tool - an integration of the quantitative Capacity Factors Analysis risk methodology and the qualitative Ostrom's framework for assessing socio-ecological systems (SESs). The new framework is used to provide a sample assessment of the Vaillapally habitation in Narayanpur Mandal, Nalgonda. Preliminary results indicate that the institutional, technical, and socio-cultural capacity factors must progress to meet the policymakers' current projects technical capacity. Alternatively, decentralized systems, such as rainwater harvesting technology, better serve rural areas with low capacity and demand, while increasing collective investment in village-scale systems.

Why do some wastewater treatment facilities work when the majority fail? Case study from the sanitation sector in Ghana

Ashley Murray Ashley Murray, Pay Drechsel Pay Drechsel

Failure is the norm for urban sanitation infrastructure in Ghana: of the rather substantial number of wastewater and faecal sludge treatment plants, with about 70 mostly decentralized systems throughout the country, less than 10 are operating effectively. This research presents an overview of the related sanitation situation in Ghana, and compares the few successful facilities with their failed counterparts in order to decipher the factors that enable the former to prevail. The research reveals important differences in the operation and maintenance (O&M) strategies, financing schemes and incentive structures in the successful versus unsuccessful facilities, which are probably not unique to Ghana. Based on the findings, we suggest a set of guiding questions for incorporation into the existing planning, funding or general decision-making framework in order to avoid commonly observed traps, which not only undermine progress in the delivery of sanitation services but also harshly affect environmental and public health.

Why DEWATS is Still not Popular in Vietnam?

Viet‐Anh Nguyen

While large centralized sanitation projects are not affordable for most cases in urban and rural areas, the only way to increase sanitation coverage, especially for the poor, is to implement low-cost alternatives with decentralized sanitation management schemes where local community, administrative authorities and private sectors are involved in the decision making as well as in the exploitation process. Despite of that, there are some reasons discussed why decentralized wastewater management concept and its application is still not widely disseminated throughout Vietnam. Among institutional and managerial aspects there are weaknesses of environmental pollution control capacity at different, especially local levels, limitations of existing Vietnamese environmental standard system, and lacking of incentive measures to encourage consultants to go for the decentralized wastewater concept, as well as to force polluters to improve their situation. In term of finance, discussed pints are low wastewater fee, and limited participation of private sector in the business. In technical aspects, there are limited information of appropriate and proven technical options for different contexts, lessons on their performance and system setting up. Besides, difficulties in the household connection and in collection network are among factors. The paper also provides some examples of decentralized alternatives implemented in different sanitation projects at different scales in Vietnam.

The challenges of achieving high training coverage for IMCI: case studies from Kenya and Tanzania

Honoratha Mushi, K. Mullei, J. Macha, Francis Wafula · 7 authors

Health worker training is a key component of the integrated management of childhood illness (IMCI). However, training coverage remains low in many countries. We conducted in-depth case studies in two East African countries to examine the factors underlying low training coverage 10 years after IMCI had been adopted as policy. A document review and in-depth semi-structured interviews with stakeholders at facility, district, regional/provincial and national levels in two districts in Kenya (Homa Bay and Malindi) and Tanzania (Bunda and Tarime) were carried out in 2007-08. Bunda and Malindi achieved higher levels of training coverage (44% and 25%) compared with Tarime and Homa Bay (5% and 13%). Key factors allowing the first two districts to perform better were: strong district leadership and personal commitment to IMCI, which facilitated access to external funding and encouraged local-level policy adaptation; sensitization and training of district health managers; and lower staff turnover. However, IMCI training coverage remained well below target levels across all sites. The main barrier to expanding coverage was the cost of training due to its duration, the number of facilitators and its residential nature. Mechanisms for financing IMCI also restricted district capacity to raise funds. In Tanzania, districts could not spend more than 10% of their budgets on training. In Kenya, limited financial decentralization meant that district managers had to rely on donors for financial support. Critically, the low priority given to IMCI at national and international levels also limited the expansion of training. Levels of domestic and donor support for IMCI have diminished over time in favour of vertical programmes, partly due to the difficulty in monitoring and measuring the impact of an integrated intervention like IMCI. Alternative, lower cost methods of IMCI training need to be promoted, and greater advocacy for IMCI is needed both nationally and internationally.

Key challenges in the governance of rural water supply: lessons learnt from Tanzania

Alejandro Jiménez Fernåndez de Palencia

El primer objetivo de esta tesis es la identificaciĂłn y anĂĄlisis de aspectos clave para la gobernanza de los servicios de agua rural en paĂ­ses que adolecen de bajos niveles de cobertura, altos Ă­ndices de pobreza, se encuentran en procesos de descentralizaciĂłn, reciben un importante apoyo de donantes internacionales. Esta situaciĂłn es comĂșn para muchos paĂ­ses de África Sub-sahariana. Por ello, se eligiĂł Tanzania como objeto de estudio. El segundo objetivo de esta tesis ha sido el ensayo de nuevas herramientas y mecanismos institucionales para la mejora de la eficiencia, equidad y sostenibilidad en la provisiĂłn de agua en las zonas rurales, con especial Ă©nfasis en el nivel de gobierno descentralizado. Para ello, se desarrollaron experiencias piloto asĂ­ como procesos de investigaciĂłn-acciĂłn. En el capĂ­tulo 1 se estudia el papel desempeñado por los diferentes actores internacionales en la financiaciĂłn del sector del agua en los paĂ­ses en desarrollo durante la dĂ©cada 1995-2004. En el capĂ­tulo 2 se analizan los indicadores existentes para el seguimiento del sector del agua a nivel internacional, especĂ­ficamente los utilizados para valorar el cumplimiento de los Objetivos del Milenio, asĂ­ como el Índice de Pobreza HĂ­drica (Water Poverty Index). Se detallan algunos limitantes en cuanto al alcance y metodologĂ­a de cĂĄlculo de estos indicadores, y se proponen las caracterĂ­sticas bĂĄsicas que los indicadores deben tener para apoyar la toma de decisiones a nivel gubernamental. En el capĂ­tulo 3 se presenta una metodologĂ­a para el desarrollo de indicadores mĂĄs completos de acceso al agua, basĂĄndose en el Mapeo de Puntos de Agua (Water Point Mapping-WPM). La metodologĂ­a propuesta, denominada Mapeo Mejorado de Puntos de Agua, incluye la mediciĂłn de parĂĄmetros bĂĄsicos de calidad del agua y estacionalidad de los servicios. La factibilidad y pertinencia de la adopciĂłn de esta metodologĂ­a a nivel nacional se desarrollĂł satisfactoriamente a modo de experiencia piloto en dos distritos de Tanzania, con una poblaciĂłn rural aproximada de 840.000 personas (capĂ­tulo 4). En el capĂ­tulo 5 se analiza la sostenibilidad de los servicios de agua rural en relaciĂłn al tipo de tecnologĂ­a utilizada para el abastecimiento. El anĂĄlisis se basa en los datos de 6814 puntos de agua, sobre una poblaciĂłn equivalente al 15% de la poblaciĂłn rural de Tanzania. El capĂ­tulo 6 se analiza el proceso de toma de decisiones, desde el nivel central al nivel comunitario, para la asignaciĂłn de recursos en el sector del agua rural. Los resultados en los 4 distritos estudiados muestran que menos de la mitad de los proyectos asignados se destinan a zonas con baja cobertura de servicios. Las incoherencias entre el diseño y la implementaciĂłn de los planes nacionales, y la influencia de los poderes polĂ­ticos locales son los mayores obstĂĄculos para una equitativa distribuciĂłn de los recursos. El capĂ­tulo 7 detalla el caso de investigaciĂłn-acciĂłn ejecutado a nivel de gobierno local entre 2006 y 2009 con el gobierno del distrito de Same, Tanzania. La mejora de la equidad y la sostenibilidad se fomentaron mediante el desarrollo de herramientas de planificaciĂłn basadas en el WPM y de mecanismos institucionales para el apoyo a largo plazo a los sistemas de agua rurales. En el capĂ­tulo 8 se detallan las conclusiones generales y lĂ­neas de investigaciĂłn futuras. La resoluciĂłn de los desafĂ­os principales encontrados implican la adopciĂłn de paradigmas diferentes: i) la aceptaciĂłn del agua rural como un servicio responsabilidad del gobierno y no de las comunidades; ii) las actuaciones deben decidirse en funciĂłn de las necesidades de las comunidades, y no de su capacidad de demanda, iii) el establecimiento de sistemas de informaciĂłn internos que partan desde el nivel local y estĂ©n adaptados a las capacidades de actualizaciĂłn disponibles, iv) el desarrollo de mecanismos para la orientaciĂłn y el seguimiento cercano de los procesos de toma de decisiĂłn a nivel local The first objective of this thesis is the identification and analysis of key issues in the governance of rural water services in countries that suffer from a lack of rural water access, high levels of poverty, are under decentralization processes and receive significant donor support. This is a common situation for many Sub-Saharan countries. To address the relevant aspects, Tanzania was taken as a case study and was analyzed in depth. The second objective was to test tools and propose institutional arrangements at that can improve efficiency, equity and sustainability in the provision of water for the rural areas, with special focus at the local government level. This was made through pilot experiences and an action research case study. In Chapter 1 we analyse the role played by the international actors in the financing of the water sector of developing countries, in the period 1995-2004. In Chapter 2 we study existing indicators for international monitoring, specifically the ones used by the Joint Monitoring Programme for the monitoring of the MDGs, as well as the Water Poverty Index (WPI). Some drawbacks are found the indicators’ scope and methodology, which prevents them from being used as policy drivers at national level. The chapter concludes by proposing the main characteristics that those indicators must entail to be useful for governmental decision making. In Chapter 3, a methodology to define water access indicators, based on GIS-based Water Point Mapping (WPM) is proposed. The methodology, named Enhanced Water Point Mapping (EWPM), includes the measurement of basic parameters of quality of water and seasonality of the service. The feasibility and relevance of adopting this methodology at national level was tested with success in two districts in Tanzania, covering a rural population of approximately 840,000 people, as described in Chapter 4. In chapter 5, we analyze the sustainability of systems over time, and the relation between sustainability and technology; this chapter is based on the study of 6814 water points, covering 15% of the rural population in the country. Chapter 6 analyses the aspects affecting financial resource allocation for rural water in Tanzania at all levels, from central government to village level. Results in four districts studied showed that less than half of allocated projects go to underserved areas. Incoherencies between the design and the implementation of the plans and political influences at local level are highlighted as major obstacles to the effective, equitable allocation of resources. In chapter 7, we describe an action research process that was carried out at local government level, together with Same District Council, between 2006 and 2009. The improvement of equity and sustainability was supported through the development of EWPM based planning tools and new institutional arrangements for the long-term support of community managed water supplies. In Chapter 8 the overall conclusions and future research lines are presented. We propose some new paradigms in the sector: i) rural water supply must be considered as a service, with government and not communities as main duty bearers; ii) the adoption of a needs-based approach to projects planning at community level, instead of the current demand driven, iii) the establishment of bottom-up internal information systems adapted to available updating capacities and iv) the development of mechanisms for the guidance and close monitoring of local government decision-making.

Building the role of local government authorities towards the achievement of the human right to water in rural Tanzania

Alejandro Jiménez, Agustí Pérez Foguet

Abstract In recent decades, many changes have occurred in the approach to financing and operating water services in developing countries. The demand‐responsive approach is now adopted in many countries in a context of donor‐supported decentralization processes, which gives more responsibility to end users. However, the government's responsibility at different levels is enforced by the international recognition of the human right to water. This paper examines specific actions that build the role of local government authorities in this scenario. A collaboration between an international NGO and a rural district in Tanzania from 2006 to 2009 is used as an action research case study that is representative of local capacity‐building needs in decentralized contexts and rural areas. Three main challenges were detected: i) lack of reliable information; ii) poor allocation of resources in terms of equity; and iii) lack of long‐term community management support from the district. Two mechanisms were established: i) water point mapping as a tool for information and planning; and ii) a District Water and Sanitation Unit Support (DWUS) for community management. The results show how the framework provided by the goal of human right to water helps to define useful strategies for equity‐oriented planning and post‐project support at the local level.

Newborn healthcare in India: The road ahead

Vinod K. Paul

Neonatal mortality in the country continues to be unacceptably high and unrelenting with wide variations across states. Six high population states account for 60% burden of neonatal deaths. Most of the evidence-based interventions are reflected in the programs, but the coverage levels are low due to poor implementation resulting from missed opportunities and weak health systems. Action is required at the home and community level, as well as at the outreach and facility levels in rural and urban settings. ASHAs must be engaged in home care of neonates. Private sector needs to be involved for providing care to neonates of poor families. Demand side financing and incentives could be game-changers in enhancing care seeking and service uptake. Effective programming would require still higher budgets, decentralized planning, managerial support, proper monitoring and a massive human resources capacity development. Community mobilization is essential for which panchayati raj institutions can play an important role. Advoa.cy efforts should not be diluted because there still is a long way to attain an acceptable level of newborn survival.

Neurotoxicants: Environmental Contributors to Disability in Children

Apart from the budget and service delivery concerns associated with larger caseloads in schools, parents and professionals alike seek explanations for why so many of our children are receiving diagnoses such as attention deficit hyperactivity disorder or those under the autism spectrum. Recent research reveals that exposures to neurotoxicants such as lead, mercury, and pesticides can have a particularly detrimental impact on brain function and in turn lead to the expression of learning and developmental disabilities, including speech, language, and hearing disorders (Miller & Snow, 2004; Schettler, Stein, Reich, Valenti, & Wallinga, 2000). The complex interaction of genetics and the environment during windows of vulnerability may lead to the expression of various disabilities. These environmental contributors to disability are often the least appreciated yet the most preventable. Children are uniquely susceptible to hazardous environmental exposures-they are not little adults (National Academy of Sciences, 1993). Exposures that occur before conception and continue through late adolescence can cause or contribute to disease and can disrupt development, learning, and behavior. For example, a child’s biological system is still developing: pound per pound they eat, drink, and breathe far more than adults and their behavior, such as crawling on the ground and putting their hands in their mouths after touching the floor, results in higher toxic exposure. Metabolism of many compounds, even common ones such as caffeine, is limited during the first six months of life, making them more vulnerable. In comparison to adults, children have periods of rapid brain growth in utero and during the first few months of life through puberty and up to 20 years of age when the brain reaches its maximum weight. The greatest neurological difference between adults and children includes the immaturity of the blood brain barrier, which is not fully developed until after 6 months of age. Rigid and predictable periods of nervous system cell proliferation, migration, and differentiation create windows of vulnerability for the young brain. These two features combined make the young brain a less stable organ and a more culpable target of toxicity when compared to the adult counterpart. To date, most learning and developmental disability groups have focused on identifying affected children and getting them the services they need-something that is, of course, very important. However, there is a parallel need for prevention of exposures that lead to or exacerbate these disabilities. Prevention of communication disorders has always been a part of the scope of practice for SLPs and audiologists. Science typically can’t identify a single chemical “cause” of a developmental or learning disability. There are hundreds of neurotoxicants and suspected neurotoxicants in production that have not been thoroughly tested for adverse health effects. Given the knowledge and experience we have gained about developmental effects of neurotoxicants, we have an ethical responsibility to protect our children (Gilbert, 2005). Therefore environmentalists and public health officials are beginning to adopt the “precautionary principle” with regard to chemical exposures. The precautionary principle states: When an activity raises threats of harm to human health or the environment, precautionary measures should be taken even if some cause and effect relationships are not fully established scientifically. In this context the proponent of an activity, rather than the public, should bear the burden of proof. The process of applying the precautionary principle must be open, informed, and democratic and must include potentially affected parties. It must also involve an examination of the full range of alternatives, including no action. (Science and Environmental Health Network, 1998). Lead Exposure Lead provides an important example of hazardous environmental exposures that may lead to disabilities because it is the most researched neurodevelopmental toxicant. Lead exposure in schools can occur through older drinking water systems with leaded pipes or from cracking and peeling paint that produces lead dust. This lead dust may be inhaled or inadvertently ingested by children, teachers, and administrators alike. More recently lead has been found in children’s jewelry, school lunch boxes, and even candy. Lead has an affinity for the central nervous system (CNS) and it deposits in bone as a substitute for calcium. Very high lead levels in blood can result in encephalopathy; very low levels can result in cognitive impairment and behavioral difficulties. In 1979 Herbert Needleman published a research paper that found an association between lead levels in teeth and difficulty following classroom instruction, unruly behavior, greater distractibility, and reduced auditory and verbal processing (Needleman et al., 1979). Lesser known CNS effects from lead include hearing and balance (Bhattacharya, Shukla, Bornschein, Dietrich, & Keith, 1990). Although blood lead levels in children and adults have been declining over the past 30 years, deterioration or renovation of homes and complexes constructed prior to 1980 can result in exposure to contaminated paint chips or dust. Lead-tainted soil can persist as long as 2,000 years and contaminated house dust remains a significant source of lead exposure for children in urban communities (Koger, Schettler, & Weiss, 2005). Children also may be exposed through inhalation of lead dust from home renovation or take-home occupational exposures of adults in the household. Poor academic performance and low intelligence test scores have been associated with even low lead levels (Needleman et al., 1979). Long-term follow up of children with early childhood exposures reveals the irreversibility of lead’s effects on cognitive and behavioral impairment (Needleman, 1998). These studies have been substantiated elsewhere (Schwartz, 1994). Recent evidence suggests that lead exposure below the current Centers for Disease Control and Prevention standard of 10 ”g/dL blood lead level results in cognitive deficits (Lanphear et al., 2005). The effects of a developmental disorder last a lifetime with societal costs measured in the billions of dollars (Landrigan, Schechter, Lipton, Fahs, & Schwartz, 2002). Prevention of childhood lead exposure at home and school is the best course of action to protect the potential of our children. Pesticide Exposure Over the years, many schools have relied on pesticide applications to control pests. However, recent research reminds us that pesticides are poisonous and many are neurotoxicants. Exposure to pesticides is linked with cancer, birth defects, and most notably, neurological and behavioral disorders. There is a movement across the nation to eliminate pesticide use at schools to manage pests and this safer alternative is called Integrated Pest Management (IPM). IPM is a method of pest control that emphasizes prevention of pests and allows the use of “least toxic” pesticides when necessary to protect human health. IPM is a shift in thinking to prevention in the first place. It eliminates the cause of pests by minimizing their access to food, water, and hiding places. Many schools are finding that implementing IPM as an “ounce of prevention” can save time and money with the added benefit of being safer for children’s neurological development and the environment. Recent examples include the Seattle, WA IPM policy (www.seattleschools.org/area/facilities/IPM/IPM.htm) and the Pennsylvania IPM policy (http://paipm.cas.psu.edu/schools/PSBApolicy.html). A good place to find more information and resources on an IPM program for schools is the Safer Pest Control Project (http://spcpweb.org) based in Chicago, IL. This project conducts site assessments, workshops, and ongoing technical assistance and maintains a speaker’s bureau that travels the surrounding states educating school administrators, homeowners, and even garden clubs on IPM implementation. The project also has a 12-minute video available for purchase entitled, “Integrated Pest Management in Schools: A Better Method.” See The ASHA Leader Online for more resources. Elemental Mercury Exposure Elemental mercury exposure in schools occurs from broken thermometers and thermostats, spills from improperly stored or handled mercury in the chemistry lab, and accidents when using mercury in the science lab for experiments. In 2004, six Environmental Protection Agency (EPA) regional offices responded to mercury spills that included 12 emergency removals from schools. EPA cleanup costs for elemental mercury in 2004 ranged from $1,000 to $200,000 per school. Elemental mercury is most toxic in its vapor form. It slowly vaporizes at room temperature and more quickly when heated. Children exposed to elemental mercury can be seriously poisoned by breathing in the invisible vapor. Elemental mercury vapor, like lead, is a well-known neurotoxicant that can disrupt normal brain development in the child and fetus. Children exposed to elemental mercury for long periods of time may have trouble learning in school, and exposure to mercury can result in communication and learning disabilities that may be irreversible (Skavroneck & Stenstrup, 1998). The EPA has developed a program, with funding, to help schools get rid of elemental mercury and many other harmful chemicals that could adversely affect children’s health. The Schools Chemical Cleanout Campaign (SC3) was started in 2004 to help schools remove potentially harmful chemicals, conduct chemical management training for lab instructors, and raise national awareness of the issue of chemicals in schools (see the Resources online for more information.) Understanding the role that exposures to neurotoxicants play in the etiology of communication disorders in our most vulnerable of populations-young children-is an important landmark because many of these exposures are either preventable or amenable to change. Through self-directed learning, SLPs and audiologists become better prepared to serve as important members of the health profession/research team. Education regarding children’s environmental health will enable the practicing SLPs and audiologists to provide parents with information using brochures and Web site information about exposures commonly found in their child’s environment. Partnerships with the Learning and Developmental Disabilities Initiative (LDDI) and its member organizations will afford researchers in the field of communication disorders opportunities to forge into new territory, taking into consideration the possible role of neurotoxicant dose and timing on the nature of hearing loss, language delays, and a host of other communication disorders in children. Educators and public health professionals can make powerful partners in taking action at local, state, and national levels to prevent exposure to neurotoxicants that lead to learning disabilities. Keeping Children Safe from Pesticides Pesticides are poisonous chemicals used in schools and around school grounds to kill weeds, insects, rodents, and fungus. Children are more vulnerable to the adverse effects of pesticides because of their smaller size, their organs still being under development, and they eat and breathe more relative to their body weight. For an adult or child, pesticide exposure is unwelcome and increases the risk of adverse health effects. Our children have a right to an environment that ensures that they have the best opportunity to reach and maintain their potential. The health effects of pesticides are well established; after all, they are designed to kill. Pesticides can affect a child’s nervous system, respiratory system, endocrine function, and some are even linked to cancer. Pesticide exposure in schools can be reduced or even eliminated by establishing an Integrated Pest Management (IPM) program. For example, in Seattle, WA a public committee was established by the Seattle School Board to examine pesticide use and consider establishing an IPM policy. The Seattle School Board adopted the following policy: It is the policy of the Seattle School Board that students and staff have a right to a healthy learning and working environment. The District will work to achieve this, in part, by reducing and eliminating the use of pesticides and other toxic chemicals through the use of Integrated Pest Management in buildings and grounds programs, as set forth in the attached procedures. The goal of this policy is to create and maintain sustainable, healthy school environments by using methods that emphasize protection of children’s health and use of ecologically sound practices, in order to achieve long-term prevention and suppression of pest problems. The above policy statement was supported by a more detailed operating procedure that outlines an IPM approach. These changes in management practice were not expected to increase costs while the use of chemicals is being reduced or even eliminated. In some cases less toxic chemicals were substituted for more toxic pesticides. More information on developing an IPM policy for your school can be found at Washington Toxics Coalition (www.watoxics.org) and School Pesticide Reform Coalition (www.beyondpesticides.org/toxicfreeschools/index.htm).

Programmatic pathways to child survival: results of a multi-country evaluation of Integrated Management of Childhood Illness

Jennifer Bryce, CĂ©sar G. Victora, Jean‐Pierre Habicht, Robert E. Black · 5 authors

OBJECTIVE: To summarize the expectations held by World Health Organization programme personnel about how the introduction of the Integrated Management of Childhood Illness (IMCI) strategy would lead to improvements in child health and nutrition, to compare these expectations with what was learned from the Multi-Country Evaluation of IMCI Effectiveness, Cost and Impact (MCE-IMCI), and to discuss the implications of these findings for child survival policies and programmes. DESIGN: The MCE-IMCI study designs were based on an impact model developed in 1999-2000 to define how IMCI would be implemented at country level and below, and the outcomes and impact it would have on child health and survival. MCE-IMCI studies included: feasibility assessments documenting IMCI implementation in 12 countries (1999-2001); in-depth studies using compatible designs in Bangladesh, Brazil, Peru, Tanzania and Uganda; and cross-site analyses addressing the effectiveness of specific subsets of IMCI activities. RESULTS: The IMCI strategy was successfully introduced in the great majority of countries with moderate to high levels of child mortality in the period from 1996 to 2001. Seven years of country-based evaluation, however, indicates that some of the basic expectations underlying the development of IMCI were not met. Four of the five countries (the exception is Tanzania) had difficulties in expanding the strategy at national level while maintaining adequate intervention quality. Technical guidelines on delivering interventions at family and community levels were slow to appear, and in their absence countries stalled in their efforts to increase population coverage with essential interventions related to care-seeking, nutrition, and correct care of the sick child at home. The full weight of health system limitations on IMCI implementation was not appreciated at the outset, and only now is it clear that solutions to larger problems in political commitment, human resources, financing, integrated or at least coordinated programme management, and effective decentralization are essential underpinnings of successful efforts to reduce child mortality. CONCLUSIONS: This analysis highlights the need for a shift if child survival efforts are to be successful. Delivery systems that rely solely on government health facilities must be expanded to include the full range of potential channels in a setting and strong community-based approaches. The focus on process within child health programmes must change to include greater accountability for intervention coverage at population level. Global strategies that expect countries to make massive adaptations must be complemented by country-level implementation guidelines that begin with local epidemiology and rely on tools developed for specific epidemiological profiles.

CONQUERING THE INTOLERABLE BURDEN OF MALARIA: WHAT’S NEW, WHAT’S NEEDED: A SUMMARY

Joel G. Breman, Martin Alilio, Anne Mills

Each year, up to three million deaths due to malaria and close to five billion episodes of clinical illness possibly meriting antimalarial therapy occur throughout the world, with Africa having more than 90% of this burden. Almost 3% of disability adjusted life years are due to malaria mortality globally, 10% in Africa. New information is presented in this supplement on malaria-related perinatal mortality, occurrence of human immunodeficiency virus in pregnancy, undernutrition, and neurologic, cognitive, and developmental sequelae. The entomologic determinants of transmission and uses of modeling for program planning and disease prediction and prevention are discussed. New data are presented from the Democratic Republic of the Congo, Tanzania, Ethiopia, and Zimbabwe on the increasing urban malaria problem and on epidemic malaria. Between 6% and 28% of the malaria burden may occur in cities, which comprise less than 2% of the African surface. Macroeconomic projections show that the costs are far greater than the costs of individual cases, with a substantial deleterious impact of malaria on schooling of patients, external investments into endemic countries, and tourism. Poor populations are at greatest risk; 58% of the cases occur in the poorest 20% of the world's population and these patients receive the worst care and have catastrophic economic consequences from their illness. This social vulnerability requires better understanding for improving deployment, access, quality, and use of effective interventions. Studies from Ghana and elsewhere indicate that for every patient with febrile illness assumed to be malaria seen in health facilities, 4-5 episodes occur in the community. Effective actions for malaria control mandate rational public policies; market forces, which often drive sales and use of drugs and other interventions, are unlikely to guarantee their use. Artemisinin-based combination therapy (ACT) for malaria is rapidly gaining acceptance as an effective approach for countering the spread and intensity of Plasmodium falciparum resistance to chloroquine, sulfadoxine/pyrimethamine, and other antimalarial drugs. Although costly, ACT ($1.20-2.50 per adult treatment) becomes more cost-effective as resistance to alternative drugs increases; early use of ACT may delay development of resistance to these drugs and prevent the medical toll associated with use of ineffective drugs. The burden of malaria in one district in Tanzania has not decreased since the primary health care approach replaced the vertical malaria control efforts of the 1960s. Despite decentralization, this situation resulted, in part, from weak district management capacity, poor coordination, inadequate monitoring, and lack of training of key staff. Experience in the Solomon Islands showed that spraying with DDT, use of insecticide-treated bed nets (ITNs), and health education were all associated with disease reduction. The use of nets permitted a reduction in DDT spraying, but could not replace it without an increased malaria incidence. Baseline data and reliable monitoring of key outcome indicators are needed to measure whether the ambitious goals for the control of malaria and other diseases has occurred. Such systems are being used for evidence-based decision making in Tanzania and several other countries. Baseline cluster sampling surveys in several countries across Africa indicate that only 53% of the children with febrile illness in malarious areas are being treated; chloroquine (CQ) is used 84% of the time, even where the drug may be ineffective. Insecticide-treated bed nets were used only 2% of the time by children less than five years of age. Progress in malaria vaccine research has been substantial over the past five years; 35 candidate malaria vaccines are in development, many of which are in clinical trials. Development of new vaccines and drugs has been the result of increased investments and formation of public-private partnerships. Before malaria vaccine becomes deployed, consideration must be given to disease burden, cost-effectiveness, financing, delivery systems, and approval by regulatory agencies. Key to evaluation of vaccine effectiveness will be collection and prompt analysis of epidemiologic information. Training of persons in every aspect of malaria research and control is essential for programs to succeed. The Multilateral Initiative on Malaria (MIM) is actively promoting research capacity strengthening and has established networks of institutions and scientists throughout the African continent, most of whom are now linked by modern information-sharing networks. Evidence over the past century is that successful control malaria programs have been linked to strong research activities. To ensure effective coordination and cooperation between the growing number of research and control coalitions forming in support of malaria activities, an umbrella group is needed. With continued support for scientists and control workers globally, particularly in low-income malarious countries, the long-deferred dream of malaria elimination can become a reality.
