Flood Trap

Introduction

Global warming is making extreme rainfall a regular event across the globe. A grass has now been developed to reduce the devastation caused by floods. A hybrid of two grasses, rye and meadow fescue, the grass helps mitigate rising floods by making the fields absorb huge amounts of rainwater water instead of letting it flow into rivers. It has been found to reduce water run-off by half. This happens as the roots of this grass make the soil more porous than traditional grasses, enabling it to absorb more water. The grass can also work as a high quality, weather resilient forage for livestock.
