Book Description
This study evaluates the effectiveness of the World Bank Group's support for health, nutrition, and population (HNP) in developing countries from 1997 to 2008 - totaling more than $17 billion - and distills lessons for greater impact in the future. It finds that the Bank Group now funds a smaller share of global support for HNP than a decade ago, but its support remains substantial and adds considerable value. About two-thirds of the Bank's HNP support has had satisfactory outcomes, often in difficult environments. But in a number of country settings, particularly in Africa, it has not performed well, in part due to high complexity and weak capacity. Only half of HNP support had a pro-poor focus, while support to reduce high fertility and promote family planning has dwindled. The evaluation highlights the contribution of investments in water supply, sanitation, and hygiene to improving the health of the poor and the lessons from support for sector-wide approaches, communicable disease control, and health reform. Moving forward, the World Bank needs to improve the performance of its HNP support and the Bank and IFC need to take actions to ensure their support reaches the poor and contributes greater social benefits, respectively.

Book Description
In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.

What Can We Learn from Nutrition Impact Evaluations?

Book Description
Evaluation Summary What Can We Learn from Nutrition Impact Evaluations? High levels of child malnutrition in developing countries contribute to mortality and have long-term consequences for children s cognitive development and earnings as adults. Recent impact evaluations show that many different interventions have had an impact on children s anthropometric outcomes (height, weight, and birth weight), but there is no simple answer to the question What works? to address the problem. Similar interventions have widely different results in different settings, owing to differences in local context, the causes and severity of malnutrition, and the capacity for program implementation. Impact evaluations of programs supported by the Bank, which are generally large-scale, complex inter-ventions in low-capacity settings, show equally variable results. The findings confirm that it should not be assumed that an intervention found effective in a randomized medical setting will have the same effects when implemented under field conditions. There are many robust experimental and quasi-experimental methods for assessing impact under difficult circumstances often found in field settings. The relevance and impact of nutrition impact evaluations could be enhanced by collecting data on service delivery, demand-side behavioral outcomes, and implementation processes to better understand the causal chain and what part of the chain is weak, in parallel with impact evaluations. It is also important to understand better the distribution of impacts, particularly among the poor, and to document better the costs and effectiveness of interventions. High levels of child malnutrition in developing countries are contributing to mortality and present long-term consequences for the survivors. An estimated 178 million children under age 5 in developing countries are stunted (low height for age) and 55 million are wasted (low weight for height). Malnutrition makes children more susceptible to illness and strongly affects child mortality. Beyond the mortality risk in the short run, the developmental delays caused by undernutrition affect children s cognitive outcomes and productive potential as adults. Micronutrient deficiencies vitamin A, iron, zinc, iodine, for example are also common and have significant consequences. Progress in reducing malnutrition has been slow: More than half of countries are not on track to achieve the Millennium Development Goal of halving the share of children who are malnou-rished (low weight for age) by 2015. The food price and financial crises are making achievement of this goal even more elusive. The World Bank has recently taken steps to ex-pand its support for nutrition in response to the underlying need and the increased urgency due to the crises. WHAT DO WE KNOW ABOUT REDUCING MALNUTRITION? The increased interest and resources focused on the problem of high and potentially increasing rates of undernutrition raises the question, what do we know about the causes of malnutrition and the in-terventions most likely to reduce it? The medical literature points to the need to inter-vene during gestation and the first two years of life to prevent child malnutrition and its consequences. It suggests that investments in interventions during this window of opportunity among children under 2 are likely to have the greatest benefits. Recently published meta-analyses of the impact evaluation literature point to several interventions found effective for reducing undernutrition in spe-cific settings. However, there are limitations to the generalizability of those reviews findings, particularly in the context of large-scale government programs most likely to be supported by the World Bank. The reviews tend to disproportionately draw on the findings of smaller, controlled experiments; there are few examples of evaluations of large-scale programs, over which there is less control in implementation. In reviewing a large number of studies, interventions, and outcomes, they tend to focus on average impacts. They generally do not explain the magnitude or variability of impacts across or within studies. Very few address the programmatic reasons why some interventions work or don t work, nor do they assess the cost-effectiveness of interventions. Objectives of the Review This paper reviews recent impact evaluations of interventions and programs to improve child anth-ropometric outcomes height, weight, and birth weight with an emphasis on both the findings and limitations of the literature and on understanding what might happen in a non-research setting. It further reviews in greater detail the experience and lessons from evaluations of the impact of World Bank-supported programs on nutrition outcomes. Specifically, the review addresses four questions. First, what can be said about the impact of different interventions on children s anthropometric outcomes? Second, how do these findings vary across settings and within target groups, and what accounts for this variability? Third, what is the evidence of the cost-effectiveness of these interventions? Finally, what have been the lessons from implementing impact evaluations of Bank-supported programs with anthropometric impacts? While there are different dimensions of child nutri-tion that could be explored, the report focuses on child anthropometric outcomes -- weight, height, and birth weight. These are the most common nutrition outcome indicators in the literature and the most frequently monitored by national nutrition programs supported by the World Bank. Low weight for age (underweight) is also the indicator for one of the MDGs. Methodology and Scope Forty-six nutrition impact evaluations published since 2000 were systematically reviewed. These evaluations assessed the impact of diverse interven-tions community nutrition programs, conditional and unconditional cash transfers, early child devel-opment programs, food aid, integrated health and nutrition services, and de-worming. All of the evaluations used research designs that compared the outcomes among those affected by the project to the counterfactual that is, what would have happened to a similar group of people in the absence of the intervention. About half used randomized assignment to create treatment and control groups, while the remainder used matching and various econometric techniques to construct a counterfactual. Among the 46 evaluations, twelve assessed the im-pact of World Bank-supported programs on nutri-tion outcomes in eight countries. While the broader review relies on the analysis of the published impact evaluations as the main source of data, for these twelve evaluations project documents and research outputs were reviewed and World Bank staff, country officials and the evaluators and re-searchers who conducted the studies were interviewed. Findings A wide range of interventions had a positive impact on indicators related to height, weight, wasting, and low birth weight. There were a total of 10 different outcome indica-tors for the four main anthropometric outcomes. A little more than half of the evaluations addressing a height-related indicator found program impacts on at least one group of children, and this was true for about the same share of interventions aimed at improving weight-related and wasting (low weight for height)-related indicators. About three-quarters of the 11 evaluations of interventions that aimed at improving birth weight indicators registered an impact in at least one specification, including five out of seven micronutrient interven-tions. There was no clear pattern of impacts across interventions in every intervention group there were examples of programs that did and did not have an impact on a given indicator, and with varying magnitude. Evaluations of the nutritional impact of programs supported by the World Bank, which are generally large-scale, complex, and implemented in low-capacity settings, show equally variable results. Even controlling for the specific outcome indicator, studies often targeted children of different age groups that might be more or less susceptible to the interventions. It is thus difficult to point to inter-ventions that are systematically more effective than others in reducing malnutrition across diverse set-tings and age groups. Differences in local context, variation in the age of the children studied, the length of exposure to the intervention, and differing methodologies of the studies account for much of the variability in results. Context includes factors like the level and local determinants of malnutrition, differences in the characteristics of beneficiaries (including their age), the availability of service infrastructure, and the implementation capacity of government. Outside of a research setting in the context of a large government program there are many things that can go wrong in either service delivery or the demand response that can compromise impact. Beyond this, there are social factors like the status of women or the presence of civil unrest that can affect outcomes. These findings underscore the conclusion that it should not be assumed that an intervention found effective in a randomized controlled trial in a re-search setting will have the same effects when im-plemented under field conditions in a different set-ting. They also point to the need to understand the prevailing underlying causes of malnutrition in a given setting and the age groups most likely to benefit in selecting an intervention. Further, impact evaluations need to supplement data measuring impact with data on service delivery and demand-side behavioral outcomes to demonstrate the plausibility of the findings, to understand what part of a program works, and to address weak links in the results chain to improve performance. There is scant evidence on the distribution of nutrition impacts who is benefiting and who is not or on the cost-effectiveness of interventions Just because malnutrition is more common among the poor does not mean that they will disproportio-nately benefit from an intervention, particularly if acting on new knowledge or different incentives relies on access to education or quality services. Only a third of the 46 evaluations looked at the distribution of impacts by gender, mother s education, poverty status, or availability of complementary health services. Only nine assessed the impacts on nutritional outcomes of the poor compared with the non-poor. Among the evaluations that did examine variation in results, several found that the children of more educated mothers or in better-off communities are be-nefitting the most. Bank-supported cash transfers, community nutrition, and early child development programs in six of eight countries had some impact on child anthropometric outcomes. Of the 12 impact evaluations of Bank support, all but one were of large-scale government programs with multiple interventions and a long results chain. Three-quarters found a positive impact on anthro-pometric outcomes of children in at least one age group, although the magnitude was in some cases not large or applied to a narrow age group. Most of the impact evaluations involved assessment of completely new programs and involved World Bank researchers. Most used quasi-experimental evaluation designs and two-thirds assessed impact after at most 3 years of program implementation. Only half of the evaluations documented the distribution of impacts and only a third presented information on the costs of the intervention (falling short of cost-effectiveness analysis). In two of the countries (Colombia and the Philippines) the evaluations likely had an impact on government policy or programs. Lessons A number of lessons for development practi-tioners and evaluators arose from the review of impact evaluations of World Bank nutrition support. For task managers: Impact evaluations of interventions that are clearly beyond the means of the government to sustain are of limited relevance. The complexity, costs, and fiscal sustainability of the intervention should figure into the decision as to whether an impact evaluation is warranted. Impact evaluations are often launched for the purpose of evaluating completely new pro-grams, but they may be equally or even more useful in improving the effectiveness of ongo-ing programs. There are methods for obtaining reliable impact evaluation results when randomized assignment of interventions is not possible for political, ethical, or practical reasons. For evaluators: In light of the challenges of evaluating large-scale programs with a long results chain, it is well worth the effort to assess the risks to disruption of the impact evaluation ahead of time and identify mitigation measures. The design and analysis of nutrition impact evaluations need to take into account the likely sensitivity of children of different ages to the intervention. For the purposes of correctly gauging im-pact, it is important to know exactly when delivery of an intervention took place in the field (as opposed to the official start of the program). Evaluations need to be designed to provide evidence for timely decision-making, but with sufficient elapsed time for a plausible impact to have occurred. The relevance of impact evaluations for po-licymakers would be greatly enhanced if im-pact evaluations were to document both the

Only nine assessed the impacts on nutritional outcomes of the poor compared with the non-poor. Among the evaluations that did examine variation in results, several found that the children of more educated mothers or in better-off communities are be-nefitting the most. Bank-supported cash transfers, community nutrition, and early child development programs in six of eight countries had some impact on child anthropometric outcomes. Of the 12 impact evaluations of Bank support, all but one were of large-scale government programs with multiple interventions and a long results chain. Three-quarters found a positive impact on anthro-pometric outcomes of children in at least one age group, although the magnitude was in some cases not large or applied to a narrow age group. Most of the impact evaluations involved assessment of completely new programs and involved World Bank researchers. Most used quasi-experimental evaluation designs and two-thirds assessed impact after at most 3 years of program implementation. Only half of the evaluations documented the distribution of impacts and only a third presented information on the costs of the intervention (falling short of cost-effectiveness analysis). In two of the countries (Colombia and the Philippines) the evaluations likely had an impact on government policy or programs. Lessons A number of lessons for development practi-tioners and evaluators arose from the review of impact evaluations of World Bank nutrition support. For task managers: Impact evaluations of interventions that are clearly beyond the means of the government to sustain are of limited relevance. The complexity, costs, and fiscal sustainability of the intervention should figure into the decision as to whether an impact evaluation is warranted. Impact evaluations are often launched for the purpose of evaluating completely new pro-grams, but they may be equally or even more useful in improving the effectiveness of ongo-ing programs. There are methods for obtaining reliable impact evaluation results when randomized assignment of interventions is not possible for political, ethical, or practical reasons. For evaluators: In light of the challenges of evaluating large-scale programs with a long results chain, it is well worth the effort to assess the risks to disruption of the impact evaluation ahead of time and identify mitigation measures. The design and analysis of nutrition impact evaluations need to take into account the likely sensitivity of children of different ages to the intervention. For the purposes of correctly gauging im-pact, it is important to know exactly when delivery of an intervention took place in the field (as opposed to the official start of the program). Evaluations need to be designed to provide evidence for timely decision-making, but with sufficient elapsed time for a plausible impact to have occurred. The relevance of impact evaluations for po-licymakers would be greatly enhanced if im-pact evaluations were to document both the

Book Description
This evaluation assesses the performance of IFC s energy efficiency finance program in China aimed at stimulating energy efficiency investments through bank guarantees and technical assistance. The difference made by the program is traced along the chain of interventions: (i) at the level of banks, the program is narrowly based on one of the two partner banks, which, with the help of the program, expanded its energy efficiency lending as a new business line; (ii) at the level of energy management companies, the program s technical assistance improved the program participants access to finance; and (iii) at the end-user level, it promoted the use of energy efficiency investments that achieved reduction of greenhouse gas emissions. The utilization of IFC s program has been rapid compared with other similar programs. The energy efficiency investments supported by the program have reduced greenhouse gas emissions by 14 million CO2 tons per year, slightly in excess of the target set at the beginning of the program. However, there is only a weak differentiation in behavior surrounding energy efficiency investment between end users supported by the program and other similar companies that were not. It is important to note that the performance of the program was heavily influenced by the government s policy actions and the earlier efforts of other players: The Chinese government and other players such as the World Bank. The CHUEE program, relying mainly on commercial funding through IFC s guarantees, builds on these efforts

Poverty Reduction Support Credits

Book Description
This evaluation examines the relevance and effectiveness of Poverty Reduction Support Credits (PRSCs), introduced by the Bank in early 2001 to support comprehensive growth, improve social conditions, and reduce poverty in IDA countries. PRSCs were intended to allow greater country-ownership, provide more predictable annual support, exhibit more flexible conditionality, and strengthen budget processes in a results-based framework. By September 2009, the Bank had approved 99 PRSCs totaling some $7.5 billion and representing 38% percent of IDA policy based lending. The evaluation finds that in terms of process, PRSCs were effective in easing conditionality, increasing country ownership and aid predictability, stimulating dialogue between central and sectoral ministries, and improving donor harmonization. In terms of content, PRSCs succeeded in emphasizing public sector management and pro-poor service delivery. Yet in terms of results, it is difficult to distinguish growth and poverty outcomes in countries with PRSCs from other better performing IDA countries. There is scope for further simplifying the language of conditionality and underpinning PRSCs with better pro-poor growth diagnostics. PRSCs can also strengthen their results frameworks and limit sector policy content in multi-sector DPLs to high-level or cross-cutting issues. Today, Bank policy has subsumed PRSCs under the broader mantle of Development Policy Lending and the rationale for a separate brand name although differences linger from the past. Since PRSCs and other policy-based lending have gradually converged in design, remaining differences compared to other Development Policy Loans should be clearly spelled out, or the separate PRSC brand name should be phased out.
