Africa is often viewed as a relatively young continent, with less than 7 per cent of the population over 60. But this is set to change. Declining fertility rates and increasing life expectancy mean that by 2050, the number of people over 60 in Africa is projected to triple to 235 million (about 9 per cent of the African population).

This demographic shift is occurring when global climate change is intensifying, leading to more frequent and severe extreme weather events such as heatwaves, flooding and tropical cyclones.

By 2050, older adults in Africa are projected to face significantly higher heat exposure due to rapid population growth and climate change, with an increase in extreme heat events. This will heighten health risks and put pressure on local services, especially in low-income areas with limited ability to cope with the strain.

As we age, it gets harder to control body temperature. Longtime health issues like heart and lung disease and diabetes make older people more likely to become dehydrated.

In Africa, many older people struggle to get the physical, mental, social and financial support they need to cope with the direct and indirect effects of extreme weather.

Urgent strategies are therefore needed to protect older people from extreme weather such as heatwaves. These include cooling infrastructure (air conditioning) and early warning systems that tell older people when it is getting dangerously hot. Climate change adaptation plans must be integrated with policies on ageing to protect older people.

I research climate gerontology — the intersection between ageing and climate change. As part of my research I am undertaking a series of Global Ageing and Climate Change Regional Dialogues in collaboration with HelpAge International. Here are the key issues we found in Africa.

Climate change is harsh on older people

Older people vary in health and mobility. Some older individuals remain active and healthy, allowing them to cope better with the disruptions caused by extreme weather. Other, less active older adults tend to be vulnerable to climate-related threats because of weaker physical health, reduced mobility and higher risk of existing disease.

In Africa, older people are at greater risk because the continent has limited basic infrastructure. This is especially the case in rural areas, where access to healthcare, clean water and emergency services is often poor. Poverty, living alone and depending on small-scale farming make them even more susceptible to extreme weather.

The impact of climate change disproportionately affects the continent, resulting in severe floods, droughts and unprecedented heatwaves.

In 2023 alone, about 15,700 people were killed in extreme weather disasters in Africa and a further 34 million people affected. Storm Daniel caused widespread devastation in Libya, displacing 2.4 million people. Kenya, Somalia and Ethiopia experienced intense rainfall and flooding. Northern Africa faced record-breaking heat, with temperatures reaching 49.0°C in Tunisia and 50.4°C in Algeria. Severe droughts hit Morocco, Algeria and Zambia, affecting millions.

Prolonged droughts and crop failures make food shortages worse and mean that older people are unable to access healthy, nutritious food.

Floods contribute to displacement and difficulties in accessing healthcare, resulting in stress and anxiety.

Older people are also affected by the digital divide. Not having as much access to digital tools like smartphones means they cannot always get the information they need. They may not be able to see climate change education programmes, or get early warnings of extreme weather.

Solutions

Traditional knowledge: This is the understanding and practices that older people in Africa have gained over generations about their local environment. It includes knowing about climate patterns, resource use and disaster preparedness. Recognising this valuable knowledge can help communities adapt to climate change and strengthen local community resilience.

Regular assessments: Local authorities and community organisations must monitor how older people are coping with climate impacts. This will lead to more effective adaptation strategies that make use of their insights.

Healthy ageing: Older people need support to take care of their bodies, minds and social lives so that they can stay active and remain independent. Healthy ageing helps prevent illness and disabilities and allows older adults to connect with communities and cope with extreme weather.

One-stop shops for older people: These should be set up by community-based organisations, charities and government agencies to provide services such as financial assistance, healthcare and nutrition support specifically tailored for older people. They could also train older people to adapt to climate change.

Involve older people in climate adaptation: Through their local organisations, older people should be involved in disaster risk reduction plans.

Older people have already played vital roles in climate adaptation efforts across Africa. In Kenya, their mobilisation for national tree planting initiatives shows what a great contribution older people can make to the environment. A group of different generations also works together in Kenya on Agriculture for the Aged — planting climate-resilient crops to cope with unpredictable weather patterns.

Policy changes needed

For these solutions to become a reality, policies and budgets are needed.

First, policymakers should consult older people and their representatives when they draw up climate resilience strategies. Region-specific strategies are best. For example, when setting up community-based early warning systems for extreme weather events, local authorities could work with non-governmental organisations to create a system that provides timely alerts aimed at older people.

Second, age-friendly infrastructure, such as accessible healthcare facilities and housing that can withstand extreme weather, must be set up.

Third, stronger laws and political commitment will result in stronger policies for older people. The lack of political will often results in insufficient attention and resources being allocated to the needs of older people in climate action. Without strong commitment from policymakers, older populations are frequently overlooked. This limits their ability to adapt effectively.

Fourth, social protection systems such as cash transfer programmes must be improved to give financial help to vulnerable older people. Programmes that provide direct support and jobs in projects that protect against climate impacts are also a good idea.

To make this happen, governments and institutions must start collecting more data on how older people are affected by climate change. By developing inclusive policies, we can promote healthy ageing while empowering older adults to play an active role in building climate resilience.
