The Politics of Flood Forecasting

Can better cross-border co-operation and collaboration save lives in South Asia’s floods? Plus, how to protect Caribbean coral reefs from Lionfish. And, what dinosaur teeth reveal.

International Flood Forecasting
The Uttarakhand region of northern India has recently seen the heaviest rains in 80 years. The floods which followed are thought to have led to the deaths of over 5,700 people, according to official figures released this week. Every year we hear similar stories after floods in South Asia. Yet better cross-border co-ordination and collaboration on both flood warning and evacuation could save many lives. We look at the problem and the solutions.

Invading Fish
Red Lionfish, an invasive species from the Pacific are creating problems in the Caribbean. The poisonous fish, which were accidentally introduced to the region through escaping from aquariums, are now everywhere. They eat other fish and threaten the coral reef ecosystems. We look at the solutions to dealing with the problem – the chief one is to catch them and eat them.

Dinosaurs in Action
Paleontologists are uncovering new details about how dinosaurs lived by looking at their teeth. From the shape of the teeth of herbivorous species to a T-Rex tooth lodged in the tail of another dinosaur it was trying to eat, we discover what and how dinosaurs ate.
