Flood Alleviation within Rural Development

This gallery of images records a 2014 survey of FRM/’ALFA’ potential along the rural England-Wales border. Evidence exists there of opportunities, primarily by attenuation, to exploit CAP Pillar 2 incentive for community FRM investment by Adaptive Landuse (Ecosystem Service). Approaching 100 locations of interest are identified. Such sites, when characterized, should be visible also to spatial targeting software.

Hybrid grass ‘could reduce flooding impact’

Mark Kinver,  BBC News Environment reporter, writes:-

“A hybrid farmland grass, developed by a team of UK researchers, could help reduce flooding, a study has shown. A team of plant and soil scientists said tests showed the new cultivar reduced run-off by 51%, compared with a variety widely used to feed livestock. They added that rapid growth and well developed root systems meant that more moisture was retained within the soil rather than running into river systems.

The novel grass is a hybrid of perennial ryegrass (Lollium perenne) – which is widely planted by farmers for grazing livestock – and meadow fescue (Festuca pratensis), which has environmental stress-resistant characteristics.

Co-author Kit Macleod, senior research scientist at the James Hutton Institute based in Aberdeen, said a long-term project had been developing novel forage grasses but their environmental benefits had not really been tested.”

The findings appear in the journal Scientific Reports.
