Shaping a Cooler Bangkok: Tackling Urban Heat for a More Livable City

Abstract
In 2024, global temperatures reached record highs multiple times, highlighting the growing severity of extreme heat and the widespread implications. By 2050, Bangkok, already prone to high temperatures, can see extreme heat risks to health, productivity, economic growth, and infrastructure. The Urban Heat Island (UHI) effect exacerbates these challenges, making some districts, including those with high concentrations of vulnerable populations, significantly hotter than surrounding rural areas. This report, developed by the Bangkok Metropolitan Administration (BMA), in partnership with the World Bank, examines the growing threat of extreme urban heat in Bangkok, long-term trajectories, and potential impacts. It also quantifies the health, economic, and infrastructure costs associated with rising temperatures and explores targeted interventions and strategic reforms - particularly for the city’s most vulnerable communities.

    Modeling Spatio-Temporal Characteristics of Urban Heat in Bangkok
    (Washington, DC: World Bank, 2025-07-01) Acero, Juan A.; Sinh, Vivek K.; Rubinyi, Steven L.
    Urban areas accumulate heat, developing distinct urban climates that differ from the regional climate, leading to elevated mean air temperatures within cities. In tropical climates, such as Bangkok, this urban heat can contribute to high levels of heat stress. This study analyzes the spatial and temporal variation of air temperature in the Bangkok Metropolitan Administration (BMA) using dynamic climate modeling (WRF, v4.2). The analysis focuses on three distinct cli-matic periods: the cool and dry season (November–February), the hot and dry season (March–May), and the wet monsoon season (June–October). Results indicate that during sunrise in the cool and dry season, urban temperatures can be up to 6.4°C higher than those in surrounding rural areas. The highest temperature differences (>4°C) occur at night during this season, with over 50% of BMA’s urban area and population experiencing sustained exposure to these ele-vated temperatures. In contrast, the smallest temperature differences occur in the hot and dry season, despite it being the hottest overall, due to low soil moisture limiting rural cooling. Un-der specific conditions, an urban cool island (Turban < Turban) may develop during the daytime. Compact urban areas exhibit the most significant heating, although vegetated areas within BMA are also affected. These findings support the design of targeted mitigation strategies.

    Unlivable
    (Washington, DC: World Bank, 2023-12-20) Roberts, Mark; Deuskar, Chandan; Jones, Nicholas; Park, Jane
    Amid continuing urban growth and the accelerating effects of climate change, East Asian cities suffer from more extreme temperatures than surrounding rural areas - being up to 2 degrees Celsius hotter on average. This urban heat island (UHI) effect is caused by cities’ relative lack of vegetation, the prevalence of impervious surfaces, construction of buildings in locations that block breezes, releases of heat from cars and machinery, and other features of the urban environment. In the decades ahead, the UHI effect will interact with climate change in ways that make cities even more prone to heat waves - already increasing in frequency and intensity - especially among East Asian cities in tropical zones and in low- and middle-income countries. Extreme heat not only lowers the economic competitiveness and livability of cities in the region but also increases the risk of death and illness. Groups such as low-income residents, outdoor workers, and the region’s growing elderly population are the most vulnerable to extreme heat. The poor are also more likely to bear the brunt of these harms: certain urban neighborhoods, particularly poorer ones, may be several degrees hotter than others within the same city. This report uses satellite data, on-the-ground data collection, and a review of economic literature to shed new light on the magnitude of the UHI effect and its impacts on East Asian cities. Using a “Places, People, Institutions” framework, the report provides practical suggestions to help policy makers to rise to the extreme urban heat challenge. These actions, such as promoting urban greening, adopting heat-resilient urban design, and implementing heat wave early warning systems - can help to protect East Asia’s urban residents from the impacts of extreme heat, contributing to cities that are more competitive, livable, and inclusive.

    Guide to Climate Change Adaptation in Cities
    (World Bank, Washington, DC, 2011) World Bank Group
    Cities face significant impacts from climate change, both now and into the future. These impacts have potentially serious consequences for human health, livelihoods, and assets, especially for the urban poor, informal settlements, and other vulnerable groups. Climate change impacts range from an increase in extreme weather events and flooding to hotter temperatures and public health concerns. Cities in low elevation coastal zones, for instance, face the combined threat of sea-level rise and storm surges. The specific impacts on each city will depend on the actual changes in climate experienced (for example, higher temperatures or increased rainfall), which will vary from place to place. Climate change will increase the frequency at which some natural hazards occur, especially extreme weather events, and introduce new incremental impacts that are less immediate. However, few climate impacts will be truly unfamiliar to cities. Cities have always lived with natural hazards, such as earthquakes, tsunamis, hurricanes, and flooding. In some situations, cities will experience an increase in the frequency of existing climate-related hazards, such as flooding. Climate change considerations can be integrated with disaster risk reduction (DRR) in cities. DRR efforts already familiar to many may be used as a platform from which to develop climate change adaptation plans. In practical terms, disaster risk reduction and climate adaptation can be integrated in many instances, although cities should also consider incremental or gradual changes in climate that affect government operations or community life in less immediate and visible ways than conventional disasters. Approaches to collecting information on climate change impacts in a city can range from highly technical and resource-intensive, to simple and inexpensive. Technically complex assessments are likely to require collaboration with external experts, if a city is not large or well-resourced with sufficient in-house capacity.

    Indispensable Ocean : Aligning Ocean Health and Human Well-Being
    (Global Partnership for Oceans, Washington, DC, 2013-10-16) Blue Ribbon Panel
    A healthy ocean is fundamental to human wellbeing and an indispensable part of the Earth's life-support system, which sustains the species and the ecosystems upon which we depend. The ocean regulates our climate and, as part of the hydrological cycle, drives weather patterns that determine rainfall, droughts, and floods. The ocean has also reduced the impact of human-induced climate change by absorbing 25 percent of the carbon dioxide released by human activities and over 90 percent of the extra heat trapped by rising concentrations of atmospheric greenhouse gases. The ocean also provides food and sustains livelihoods. The size and growth of the human population is putting unprecedented pressure on natural resources, both on land and in the sea. The ocean may play an increasing role in supplying those resources and will, in this regard, play a critical role in global efforts to reduce poverty and improve livelihoods. Comprehensive global estimates of the economic activity associated with the ocean have only recently been attempted and a published consensus estimate has not yet emerged. The global economic benefits derived from the ocean's goods and services are, however, undeniably important, especially for coastal states and island nations. The ocean generates hundreds of millions of jobs in biotechnology, energy, fishing, shipping, tourism, and other sectors. Most current economic assessments do not yet fully account for the innumerable non-market ecosystem services that can deeply influence well-being, traditions, cultures, faith, and recreation and enjoyment for many millions of people.

    Weather and Child Health in Rural Nigeria
    (World Bank, Washington, DC, 2012-10) Rabassa, Mariano; Skoufias, Emmanuel; Jacoby, Hanan G.
    The effect of weather shocks on children's anthropometrics is investigated using the two most recent rounds of the Nigeria Demographic and Health Survey. For this purpose, climate data for each survey cluster are interpolated using daily weather-station records from the national network. The findings reveal that rainfall shocks have a statistically significant and robust impact on child health in the short run for both weight-for-height and height-for-age, and the incidence of diarrhea. The impacts of weather shocks on health are of considerable magnitude; however, children seem to catch up with their cohort rapidly after experiencing a shock. The paper does not find any evidence of nonlinear impacts of weather variability on children's health, suggesting that a moderate increase in future rainfall variability is not likely to bring additional health costs. Finally, it appears that the impact of these shocks is the same for young boys and girls, which suggests that there is no gender-based discrimination in the allocation of resources within households.

    Global Economic Prospects, June 2025
    (Washington, DC: World Bank, 2025-06-10) World Bank
    The global economy is facing another substantial headwind, emanating largely from an increase in trade tensions and heightened global policy uncertainty. For emerging market and developing economies (EMDEs), the ability to boost job creation and reduce extreme poverty has declined. Key downside risks include a further escalation of trade barriers and continued policy uncertainty. These challenges are exacerbated by subdued foreign direct investment into EMDEs. Global cooperation is needed to restore a more stable international trade environment and scale up support for vulnerable countries grappling with conflict, debt burdens, and climate change. Domestic policy action is also critical to contain inflation risks and strengthen fiscal resilience. To accelerate job creation and long-term growth, structural reforms must focus on raising institutional quality, attracting private investment, and strengthening human capital and labor markets. Countries in fragile and conflict situations face daunting development challenges that will require tailored domestic policy reforms and well-coordinated multilateral support.

    Digital Progress and Trends Report 2023
    (Washington, DC: World Bank, 2024-03-05) World Bank
    Digitalization is the transformational opportunity of our time. The digital sector has become a powerhouse of innovation, economic growth, and job creation. Value added in the IT services sector grew at 8 percent annually during 2000–22, nearly twice as fast as the global economy. Employment growth in IT services reached 7 percent annually, six times higher than total employment growth. The diffusion and adoption of digital technologies are just as critical as their invention. Digital uptake has accelerated since the COVID-19 pandemic, with 1.5 billion new internet users added from 2018 to 2022. The share of firms investing in digital solutions around the world has more than doubled from 2020 to 2022. Low-income countries, vulnerable populations, and small firms, however, have been falling behind, while transformative digital innovations such as artificial intelligence (AI) have been accelerating in higher-income countries. Although more than 90 percent of the population in high-income countries was online in 2022, only one in four people in low-income countries used the internet, and the speed of their connection was typically only a small fraction of that in wealthier countries. As businesses in technologically advanced countries integrate generative AI into their products and services, less than half of the businesses in many low- and middle-income countries have an internet connection. The growing digital divide is exacerbating the poverty and productivity gaps between richer and poorer economies. The Digital Progress and Trends Report series will track global digitalization progress and highlight policy trends, debates, and implications for low- and middle-income countries. The series adds to the global efforts to study the progress and trends of digitalization in two main ways: · By compiling, curating, and analyzing data from diverse sources to present a comprehensive picture of digitalization in low- and middle-income countries, including in-depth analyses on understudied topics. · By developing insights on policy opportunities, challenges, and debates and reflecting the perspectives of various stakeholders and the World Bank’s operational experiences. This report, the first in the series, aims to inform evidence-based policy making and motivate action among internal and external audiences and stakeholders. The report will bring global attention to high-performing countries that have valuable experience to share as well as to areas where efforts will need to be redoubled.

    Global Economic Prospects, January 2025
    (Washington, DC: World Bank, 2025-01-16) World Bank
    Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.

    The Container Port Performance Index 2023
    (Washington, DC: World Bank, 2024-07-18) World Bank
    The Container Port Performance Index (CPPI) measures the time container ships spend in port, making it an important point of reference for stakeholders in the global economy. These stakeholders include port authorities and operators, national governments, supranational organizations, development agencies, and other public and private players in trade and logistics. The index highlights where vessel time in container ports could be improved. Streamlining these processes would benefit all parties involved, including shipping lines, national governments, and consumers. This fourth edition of the CPPI relies on data from 405 container ports with at least 24 container ship port calls in the calendar year 2023. As in earlier editions of the CPPI, the ranking employs two different methodological approaches: an administrative (technical) approach and a statistical approach (using matrix factorization). Combining these two approaches ensures that the overall ranking of container ports reflects actual port performance as closely as possible while also being statistically robust. The CPPI methodology assesses the sequential steps of a container ship port call. ‘Total port hours’ refers to the total time elapsed from the moment a ship arrives at the port until the vessel leaves the berth after completing its cargo operations. The CPPI uses time as an indicator because time is very important to shipping lines, ports, and the entire logistics chain. However, time, as captured by the CPPI, is not the only way to measure port efficiency, so it does not tell the entire story of a port’s performance. Factors that can influence the time vessels spend in ports can be location-specific and under the port’s control (endogenous) or external and beyond the control of the port (exogenous). The CPPI measures time spent in container ports, strictly based on quantitative data only, which do not reveal the underlying factors or root causes of extended port times. A detailed port-specific diagnostic would be required to assess the contribution of underlying factors to the time a vessel spends in port. A very low ranking or a significant change in ranking may warrant special attention, for which the World Bank generally recommends a detailed diagnostic.
