Editor's note

On paper, Uganda protects its citizens’ freedom of expression, whether that’s verbal or on social media and other online platforms. But the reality is very different: the government continues to use domestic laws on electronic communication to crack down on citizens, activists and politicians who criticise the president on the internet.

Migration from Central America has gotten a lot of attention in recent times, including the famous migrant caravans. But much of it focuses on the way migrants from this region – especially El Salvador, Guatemala, Nicaragua and Honduras – are driven out by gang violence, corruption and political upheaval. These factors are important and require a response from the international community. But, as Miranda Cady Hallett argues, displacement driven by climate change is significant too.
