Heat acclimatization and vulnerabilities of people living in the Sahel: The case of Senegal

Institut de Recherche pour le Développement | 2018

This study analysed the heat-related impact on mortality and morbidity for a rural population in Senegal. To evaluate the effect of the duration of heat exposure, we measured heat by the average apparent temperature (with effect of humidity) in a period preceding the event (medical visit, death) ranging from one, five, and ten to thirty days. We investigated the temperature-mortality or -morbidity relationship by vulnerable groups (children and elderly people) and by temperature type (daily minimum, maximum and average). Finally, we used three types of models: GLM, GAM and ARIMAX.

We found that, between 1984 and 2014, high heat resulted in an excess of mortality and medical diagnosed morbidity, especially among children and elderly people.

Action Plan

Commissioner Karachi

This document, Karachi Heatwave Management Plan, outlines what should happen before, during and after periods of extreme heat in Karachi. It sets out strategies that government and non-government agencies will adopt to prevent heat-related illnesses and deaths in Karachi and capacitate the public, particularly the most vulnerable residents, to take protective action. The Plan describes actions of implementation partners to ensure (1) information on weather conditions and heat health is timely and specific, (2) organizations have the capacity to respond according to their roles, and (3) strategies and actions enabling increase in effectiveness over time. In June 2015 Karachi City experienced a severe heatwave that caused over 1,200 deaths and over 50,000 cases of heat illness. The heatwave caught all levels of government and first responders off-guard, highlighting the need for inter-agency coordination, clarity in roles, and a well-publicized trigger to activate a planned response. To address this need and to prevent health impacts from future heatwaves as climate change intensifies, the Commissioner Office Karachi requested support from the Climate and Development Knowledge Network (CDKN) to develop a heatwave management plan. Karachi’s first Heatwave Management Plan is the result of a technical assistance project delivered by national and international experts between October 2016 and May 2017, working closely with the Commissioner Office and other stakeholders. The Plan will be subject to an annual performance review and updated versions will be available to implementation partners accordingly.

Too hot to handle? Heat resilience in urban South Sudan

South Sudan is at risk from the impact of climate change. This paper reviews the climate change issues faced by South Sudan, and the strategy as outlined to the United Nations. The author argues that the policy overlooks a key potential cause of future morbidity and mortality: increased ambient temperatures, particularly in urban centres due to the urban heat island effect.  The capital is especially susceptible to heat-related mortality as it faces a ‘triple threat’: rapidly rising temperatures, an at-risk population profile, and inadequate planning for the pressures of urbanisation. Four low-cost, evidence-based recommendations are given to mitigate the impact of heatwaves on human health, and it is concluded that South Sudan has great potential to become a regional leader in heat resilience.

Las islas de calor o islas térmicas se refieren al patrón térmico que se encuentra en sitios altamente urbanizados en el centro o en la periferia de las ciudades. Son generadas por la pérdida de cobertura vegetal la cual es substituida por superficies impermeables como las carreteras de asfalto, edificios de concreto, ladrillo y otros materiales de construcción, dando como resultado el cambio en el balance hídrico y radiativo superficial, generando, por lo tanto, aumentos en la temperatura de las áreas urbanizadas. La identificación de estas islas térmicas permite desarrollar medidas de adaptación en sitios puntuales de la ciudad. Con el objetivo de conocer el comportamiento de las islas de calor en el Cantón de Curridabat se realizó un análisis de las temperaturas de los últimos cuatro años obtenidas de imágenes satelitales LandSat 8. Los resultados obtenidos reflejan un patrón de calentamiento diferenciado dependiendo del nivel de urbanización y la presencia de vegetación. Así mismo, se señala la relación de estas islas de calor con diferentes grupos vulnerables de la población y la necesidad de tomar medidas considerando la situación actual y futura con los cambios probables del clima. Análisis relacionados con la vegetación remanente en el cantón muestran la importancia de tomar acciones sobre parches de bosques en propiedades privadas y la atención al espacio verde público por habitante que muestra una situación de desigualdad dependiendo del distrito en que se ubique. Finalmente se propone la necesidad de desarrollar una definición para bosque urbano, y de acciones para atender principalmente todo lo relacionado a la adaptación al cambio climático basada en ecosistemas en la ciudad.

Emerging climate change-related public health challenges in Africa: A case study of the heat-health vulnerability of informal settlement residents in Dar es Salaam, Tanzania

Heat has the potential to become one of the most significant public health impacts of climate change in the coming decades. Increases in temperature have been linked to both increasing mortality and morbidity. Cities have been recognized as areas of particular vulnerability to heat’s impacts on health, and marginalized groups, such as the poor, appear to have higher heat-related morbidity and mortality. Little research has examined the heat vulnerability of urban informal settlements residents in Africa, even though surface temperatures across Africa are projected to increase at a rate faster than the global average.

This paper addresses this knowledge gap through a mixed-methods analysis of the heat-health vulnerability of informal settlement residents in Dar es Salaam, Tanzania. The heat exposure, sensitivity and adaptive capacity of informal settlement residents were assessed through a combination of climate analyses, semi-structured interviews with local government actors and informal settlement residents, unstructured interviews with health sector respondents, a health impacts literature review, and a stakeholder engagement workshop.

The results suggest that increasing temperatures due to climate change will likely be a significant risk to human health in Dar es Salaam, even though the city does not reach extreme temperature conditions, because informal settlement residents have high exposure, high sensitivity and low adaptive capacity to heat, and because the heat-health relationship is currently an under-prioritized policy issue. While numerous urban planning approaches can play a key role in increasing the resilience of citizens to heat, Dar es Salaam’s past and current growth and development patterns greatly complicate the implementation and enforcement of such approaches. For African cities, the findings highlight an urgent need for more research on the vulnerability and resilience of residents to heat-health impacts, because many African cities are likely to present similar characteristics to those in Dar es Salaam that increase resident’s vulnerability.

Action Plan

Arizona Department of Health Services, Arizona State University, University of Arizona | 2017

The Arizona Extreme Weather and Public Health Program’s primary climate-sensitive hazard topics include extreme heat, wildfires, air quality, drought, flooding, extreme cold, and vector-borne diseases. Extreme heat is a major concern to Arizona and a large focus of their work due to the frequency and severity of extreme heat events. A large portion of the state’s population is frequently exposed to outside temperatures above 100 degrees from May through September. Arizona experienced about 1,200 heat caused deaths during 2007–2017. In addition to extreme heat, the arid climate leads to other hazards such as flooding during monsoon season and more wildfires due to increased drought and high temperatures.


The Arizona Extreme Weather and Public Health Program facilitates the development and sharing of local knowledge of climate and health effects and the implementation of public health interventions for climate-related hazards affecting the state’s residents and visitors. Partnerships have led to several projects on extreme heat, such as heat alerts sent to schools and public and healthcare facilities that provide steps for heat safety. Additionally, local projects have assessed and improved cooling center networks, which help provide a cool space to get out of the heat during the summer. The program has created and distributed heat safety toolkits for various specific at-risk populations, including outdoor workers, older adults, and school children. The program and local partners have also increased their capacity to perform heat illness surveillance activities and coordinated a state heat preparedness workgroup.


In addition to adapting to the challenges of heat, other work has focused on understanding climate impacts on vector-borne diseases and the fungal disease called Valley fever. The program has also assisted in developing public health emergency response plans for wildfires and flooding. This work benefits various populations such as the homeless, elderly, children, local officials, and residents of low income and minority neighborhoods.

Managing health impacts of heat in South East Queensland, Australia

Heatwaves kill more people than any other natural hazard in Australia. Current literature on managing health risks of heatwaves highlights the importance of implementing urban planning measures, and engaging with vulnerable groups on a local level to better understand perceptions of risk and tailor health protection measures. This paper reviews arrangements to reduce heatwave health risks in South East Queensland in response to these themes. A literature search and document analysis, stakeholder interviews, and multi-stakeholder cross-sectoral workshops revealed that although heatwave management is not always considered by local government and disaster management stakeholders, many urban planning measures to minimize urban heat have been pursued. However, greater information from vulnerable groups is still needed to better inform heatwave management measures.

Cities have been recognized as areas of particular vulnerability to heat’s impacts on health, and marginalized groups, such as the poor, appear to have higher heat-related morbidity and mortality. Little research has examined the heat vulnerability of urban informal settlements residents in Africa, even though surface temperatures across Africa are projected to increase at a rate faster than the global average.

This paper addresses this knowledge gap through a mixed-methods analysis of the heat-health vulnerability of informal settlement residents in Dar es Salaam, Tanzania. The heat exposure, sensitivity and adaptive capacity of informal settlement residents were assessed through a combination of climate analyses, semi-structured interviews with local government actors and informal settlement residents, unstructured interviews with health sector respondents, a health impacts literature review, and a stakeholder engagement workshop.

The results suggest that increasing temperatures due to climate change will likely be a significant risk to human health in Dar es Salaam, even though the city does not reach extreme temperature conditions, because informal settlement residents have high exposure, high sensitivity and low adaptive capacity to heat, and because the heat-health relationship is currently an under-prioritized policy issue. While numerous urban planning approaches can play a key role in increasing the resilience of citizens to heat, Dar es Salaam’s past and current growth and development patterns greatly complicate the implementation and enforcement of such approaches. For African cities, the findings highlight an urgent need for more research on the vulnerability and resilience of residents to heat-health impacts, because many African cities are likely to present similar characteristics to those in Dar es Salaam that increase resident’s vulnerability.

Arizona Department of Health Services, Arizona State University, University of Arizona | 2017

The Arizona Extreme Weather and Public Health Program’s primary climate-sensitive hazard topics include extreme heat, wildfires, air quality, drought, flooding, extreme cold, and vector-borne diseases. Extreme heat is a major concern to Arizona and a large focus of their work due to the frequency and severity of extreme heat events. A large portion of the state’s population is frequently exposed to outside temperatures above 100 degrees from May through September. Arizona experienced about 1,200 heat caused deaths during 2007–2017. In addition to extreme heat, the arid climate leads to other hazards such as flooding during monsoon season and more wildfires due to increased drought and high temperatures.


The Arizona Extreme Weather and Public Health Program facilitates the development and sharing of local knowledge of climate and health effects and the implementation of public health interventions for climate-related hazards affecting the state’s residents and visitors. Partnerships have led to several projects on extreme heat, such as heat alerts sent to schools and public and healthcare facilities that provide steps for heat safety. Additionally, local projects have assessed and improved cooling center networks, which help provide a cool space to get out of the heat during the summer. The program has created and distributed heat safety toolkits for various specific at-risk populations, including outdoor workers, older adults, and school children. The program and local partners have also increased their capacity to perform heat illness surveillance activities and coordinated a state heat preparedness workgroup.


In addition to adapting to the challenges of heat, other work has focused on understanding climate impacts on vector-borne diseases and the fungal disease called Valley fever. The program has also assisted in developing public health emergency response plans for wildfires and flooding. This work benefits various populations such as the homeless, elderly, children, local officials, and residents of low income and minority neighborhoods.

Managing health impacts of heat in South East Queensland, Australia

Heatwaves kill more people than any other natural hazard in Australia. Current literature on managing health risks of heatwaves highlights the importance of implementing urban planning measures, and engaging with vulnerable groups on a local level to better understand perceptions of risk and tailor health protection measures. This paper reviews arrangements to reduce heatwave health risks in South East Queensland in response to these themes. A literature search and document analysis, stakeholder interviews, and multi-stakeholder cross-sectoral workshops revealed that although heatwave management is not always considered by local government and disaster management stakeholders, many urban planning measures to minimize urban heat have been pursued. However, greater information from vulnerable groups is still needed to better inform heatwave management measures.
