Half the world's population face severe food shortages by the end of the century as climate change takes its toll on the global harvest. Drought in the Sahal, which runs through Senegal, means many climate migrants are flocking to the capital, Dakar, to find work to feed their families. “Hot Cities” follows migrants from their villages, where farming has almost been wiped out, to the city. This film also looks at what is being done to feed Senegal in the future.
