Abstract
Climate change is impacting human health in myriad ways, including by increasing the frequency of extreme weather events, the emergence and spread of infectious diseases, and disruptions to food systems. The impacts of climate change on health—already profound—are only expected to worsen over time. Not only will the number of diseases and deaths from climate-sensitive health risks increase, but so too will the geographical range of these diseases. Low- and middle-income countries (LMICs) are expected to face a disproportionate burden of these impacts due to their higher levels of poverty and income inequality, and weak healthcare systems. With growing recognition that the climate crisis is a health crisis, the international community has expressed urgent calls for action on climate and health. The response of the health community and researchers has been largely focused on studying the link between climate change and health. A limited number of studies have established empirical links between climate conditions and the number of cases of different diseases in specific national (or subnational) contexts, particularly focusing on vector-borne and waterborne diseases. In addition, few studies have aimed to assess the economic cost associated with the health impacts of projected climate change. This report aims to address the existing knowledge gap and provide a deeper understanding of the interconnection between climate and health, in terms of the risks to human health and the economic burden of these risks. Specifically, it provides a quantitative assessment of the potential impacts of climate change based on the number of cases and the number of deaths resulting from selected vector- and water-borne diseases, stunting, and extreme heat. An assessment of the economic cost of climate change on health (in terms of both morbidity and mortality) is also provided. The analysis covers 69 LMICs with national populations exceeding 10 million people in the base year 2020. These 69 countries comprise 96 percent of the tota population of all LMICs.

Publication Eastern Africa - A study of the Regional Maize Market and Marketing Costs(World Bank, 2009-12-31)Maize is the most important staple food in the Eastern Africa region and the most widely traded agricultural commodity. Therefore, the performance of grain markets has a significant impact on people's welfare, particularly the poor, and is critical to inducing pro-poor growth in Kenya, Tanzania, and Uganda, i.e. the countries under review in this report. Marketing costs at the borders would need to be reduced but even more attention should be paid to domestic marketing costs. Policy makers in East Africa should not be misled that encouraging greater regional trade is solely a diplomatic matter. Instead, concerted public investments and policy actions at local, national, and regional levels are required. Reduced marketing costs would allow a reduction in input prices and thus production costs. This report aims to examine, identify, and quantify the factors behind the marketing costs for maize in East African countries. While a number of studies have recognized major barriers to trade in the region, few have actually quantified their relative importance or the magnitudes of these constraints on grain trade. Since much past research has been inconclusive, a key focus of this report is to identify how different barriers contribute to marketing costs within countries and across borders. It also aims to analyze whether a reduction in cross-border trade costs without a simultaneous reduction in domestic costs would be sufficient for greater regional integration in East Africa.Publication Costing Adaptation through Local Institutions(Washington, DC, 2011-02)This report presents the results of the World Bank funded project on Costing Adaptation through Local Institutions (CALI). The objectives of the CALI project are to: (1) identify the costs of adaptation through local institutions, and (2) investigate which institutions support households in adapting to climate variability, what efforts and costs are needed to realize the adaptation options, and how they facilitate adaptation to climate variability. The study has been carried out in Mali, Ethiopia, and Yemen. This report discusses the results for Mali.Publication Delivering Primary Care for Non-communicable Diseases(Washington, DC: World Bank, 2025-06-13)The global prevalence of noncommunicable diseases (NCDs) continues to escalate, leading to a substantial burden of disease. NCDs account for 74 percent of all global deaths, causing approximately 41 million fatalities annually, with cardiovascular diseases (CVDs), cancers, chronic respiratory diseases, and diabetes being the main contributors. Low- and middle-income countries (LMICs) bear a disproportionate share of this burden, experiencing around 82 percent of premature NCD-related deaths. Yet, many health systems in low- and middle-income countries are inadequately prepared to deliver comprehensive care for major NCDs, as primary health care (PHC) services mainly focus on the provision of acute and episodic care, leaving gaps in coverage and quality of essential services for the prevention, diagnosis, treatment, and long-term management of NCDs across the care continuum. While a broad range of cost-effective, equitable, and evidence-based interventions to address the growing burden of NCDs have been identified, the challenge lies in effectively delivering these interventions, particularly in health systems facing significant resource constraints. Integrating NCD care into primary health care (PHC) services is key to expanding access to care closer to communities, supporting health promotion and facilitating NCD prevention and control, and alleviating the burden of care at higher-level facilities. New strategies and innovative solutions are needed to achieve this approach and improve outcomes across the care continuum, from reducing risk factors to sustainably managing chronic conditions at the PHC level.Publication Morocco : Cost Assessment of Environmental Degradation(Washington, DC, 2003-06-30)This report is the first step in a process toward using environmental damage cost assessments for priority setting and as an instrument for integrating environmental issues into economic and social development. The report provides estimates of damage cost for several areas of the environment: air, water, land and forests, and waste disposal. The estimates should be considered as orders of magnitude and a range is provided to indicate the level of uncertainty. As areas of priority are identified, further analysis will be required for more accurate estimates. Due to data limitations, the damage cost of environmental degradation has not been estimated in several areas: industrial, hazardous, and hospital waste disposal; unsanitary landfills; degradation of natural ecosystems and biodiversity; and groundwater resource degradation and over-extraction. In addition and due to the complexity of the problem, the report only partially captures damage resulting from soil degradation. The report points t the need to further assess and quantify current and potential future damage costs related to those impacts.Publication Municipal Solid Waste Cost Calculation Technical Guidelines for Low and Middle-Income Countries(Washington, DC: World Bank, 2024-04-01)Municipal Solid Waste Cost Calculation Technical Guidelines discusses good practices for calculating investment and operating costs in the solid waste management sector illustrated through notional cost calculations for waste management functions and a combined waste management system. The report emphasizes the need to accurately determine the full costs of municipal waste services to establish recurrent financing needs and plan new investments. The publication aims to impress that funding annual operating expenses, typically higher than the annualized capital costs of investments and the single most important factor for sustaining waste operations, needs to be a key area of attention for local authorities. It emphasizes that the waste management sector is principally a net cost activity that requires financing; while investments in advanced treatment facilities and processes bring higher environmental and economic benefits, they also incur higher financial costs and hence revenue requirements. The publication aims to support the work of technical departments within municipalities that inform, advise, and guide their municipal councils and policy makers. The guidelines were developed with consideration of the state of the sector and its development trajectory in low, and middle-income countries.

Publication Gender-Based Violence Country Profile(World Bank, Washington, DC, 2023-06-01)Jamaica is a small island developing state situated in the Caribbean. It is the third largest island in the Caribbean, with an approximate population of 2.8 million and a gross domestic product (GDP) of 14.6 billion dollars. Agriculture and tourism are two of Jamaica’s main industries, with the latter contributing significantly to the country’s economy as well as the tourism industry. Jamaica has a high prevalence of gender-based violence (GBV), with a domestic violence rate that increased by 15.6 percent in 2022 compared to the previous year. Exposure to violence has been found to have negative implications for women’s physical and emotional health. Survivors were more likely to have suicidal thoughts and to use recreational drugs. The Covid-19 pandemic has intensified intimate partner violence (IPV), with a higher percentage of women reporting frequent experiences of IPV. Overall, the data highlights the need for continued efforts to prevent and address GBV in Jamaica.Publication Moldova Country Climate and Development Report(Washington, DC: World Bank, 2024-11-07)Moldova’s climate and development challenges are inextricably linked. Weak and volatile growth, highlevels of poverty, near total energy import dependence, and a strong reliance on drought-prone agricultureare all symptoms of intrinsic structural vulnerabilities. Climate-smart development policies offer a pathwayto address long-standing structural barriers to growth and accelerate convergence with European Union(EU) standards. Renewable energy and energy efficiency scale-up are crucial for improving the country’senergy security but will require substantial investments as well as full implementation of sectoral reformsto accelerate integration with EU energy markets. Adaptation investments are key, not only to manage theimpacts of climate shocks, but also to raise productivity in the most vulnerable sectors. Most funding willneed to come from the private sector, while public sector investments need to be substantially augmentedby development partners. With smart macro-fiscal policies, Moldova has the opportunity and potential toimplement these ambitious measures and lay the foundations for sustainable and resilient growth.Publication Global Economic Prospects, January 2023(Washington, DC: World Bank, 2023-01-10)Global growth is projected to decelerate sharply, reflecting synchronous policy tightening aimed at containing very high inflation, worsening financial conditions, and continued disruptions from Russia’s invasion of Ukraine. Investment growth in emerging market and developing economies (EMDEs) is expected to remain below its average rate of the past two decades. Further adverse shocks could push the global economy into recession. Small states are especially vulnerable to such shocks because of the reliance on external trade and financing, limited economic diversification, elevated debt, and susceptibility to natural disasters. Against this backdrop, it is critical that EMDE policy makers ensure that any fiscal support is focused on vulnerable groups, that inflation expectations remain well anchored, and that financial systems continue to be resilient. Urgent global and national efforts are also needed to mitigate the risks of global recession and debt distress in EMDEs, and to support a major increase in EMDE investment.Publication FY 2024 Dominican Republic Country Opinion Survey Report(Washington, DC: World Bank, 2024-10-22)The Country Opinion Survey in the Dominican Republic assists the World Bank Group (WBG) in better understanding how stakeholders in the Dominican Republic perceive the WBG. It provides the WBG with systematic feedback from national and local governments, multilateral/bilateral agencies, media, academia, the private sector, and civil society in the Dominican Republic on 1) their views regarding the general environment in the Dominican Republic; 2) their overall attitudes toward the WBG in the Dominican Republic; 3) overall impressions of the WBG’s effectiveness and results, knowledge work and activities, and communication and information sharing in the Dominican Republic; and 4) their perceptions of the WBG’s future role in the Dominican RepublicPublication Making Teacher Policy Work(Washington, DC: World Bank, 2023-11-08)This report zooms into what lies behind the success or failure of teacher policies: how teachers experience these policies, and how systems scale and sustain these policies. The report argues that for policies to be successful, they need to be designed and implemented with careful consideration of the barriers that could hinder teachers’ take-up of the policy (individual-level barriers), and the barriers that could hinder the implementation and sustainability of policies at scale (system-level barriers). Teacher polices too often fail to yield meaningful changes in teaching and learning because both their design and implementation overlook how teachers perceive, understand, and act in response to the policy and because they miss what is needed at a system level to achieve and sustain change. To avoid this, policymakers need to go beyond what works in teacher policy to how to support teachers in different contexts to adopt what works, while making sure it is implementable at scale and can be sustained over time. This requires unpacking teacher policies to consider the barriers that might hinder success at both the individual and system levels, and then putting in place strategies to overcome these barriers. The report proposes a practical framework to uncover the black box of effective teacher policy and discusses the factors that enable their scalability and sustainability. The framework distills insights from behavioral science to identify the barriers that stand in the way of the changes targeted by the policy and to develop strategies to overcome them. The framework is used to examine questions such as: What changes are required at an individual level to achieve the specific goals of a given teacher policy What barriers constrain the adoption of these changes How can the policy be better designed and implemented to tackle these barriers Moreover, the report draws on evidence from quantitative and qualitative studies on successful and failed teacher policies to examine the factors that make teacher policy operationally and politically feasible such that it can work at scale and be sustained over time.
