In a recent speech commemorating the 30th anniversary of the 1994 genocide against the Tutsi ethnic group, Rwanda’s president Paul Kagame said the international community “failed all of us”. In the years since the massacre, both country and UN leaders have admitted that more could’ve been done to prevent the genocide. International peacekeeping and security expert Walter Dorn outlines the three things the international community could’ve done to predict and
prevent the genocide.
Large swathes of an important South African river, the Vaal, are covered with a bright green blanket of water lettuce. This invasive plant, also known as Nile cabbage, causes major damage wherever it grows, hurting aquatic ecosystems and interfering with human activities. Luckily, those fighting the invasion have a small but potent weapon: a weevil species with an impressive track record of bringing water lettuce invasions under control. Julie Coetzee explains how the weevils work.
