Coastal cities face rising risk of flood losses, study says
The world's 136 largest coastal cities could risk combined annual losses of $1 trillion (750 billion euros) from floods by 2050 unless they drastically raise their defences, a study warned Sunday.

Genetic engineers create smarter toxins to help crops fight resistant pests
One of the most successful strategies in pest control is to endow crop plants with genes from the bacterium Bacillus thuringiensis, or Bt for short, which code for proteins that kill pests attempting to eat ...

Spread of crop pests threatens global food security as Earth warms
A new study has revealed that global warming is resulting in the spread of crop pests towards the North and South Poles at a rate of nearly 3 km a year. The study, published in the journal Nature Climate Change and carrie ...
Temperature alters population dynamics of common plant pests
Temperature-driven changes alter outbreak patterns of tea tortrix—an insect pest—and may shed light on how temperature influences whether insects emerge as cohesive cohorts or continuously, according ...
