Freetown, the capital of Sierra Leone, is experiencing rising temperatures, with extreme heat becoming a major challenge for residents, especially those in crowded neighbourhoods and open-air markets.

With limited access to cooling infrastructure, the heat affects daily life, health, food security and the economy.

In response, the city recently hosted an ‘Urban Heat Hackathon’, where teams developed innovative solutions to tackle the problem.

In today's Africa Daily Alan Kasujja speaks to two of the hackathon winners, Tommy Charles and Glory Aminata Turay, to explore how technology and urban greening are helping residents adapt to and mitigate extreme heat.
