Flooding and farming: level heads are needed

Feelings are running high in Somerset as parts of the Levels continue to be inundated with deep floodwater, causing untold misery to those who live and farm there. Locals are convinced that some river-dredging would have substantially reduced the length of time the land there has been underwater and offer evidence from the Environment Agency demonstrating this. The EA did start some dredging last year at 'pinch points'. I suspect the work was delayed owing to the incredibly wet summer - a lot of land-related contract work just didn't get done in 2012 - a large area of the Levels was flooded at the time.

There's a lot to consider about how the Levels should be managed, and the debate needs to cover all bases, not just be confined to dredging. However, to date there hasn't been a rounded debate - and this is badly needed. It is vital to look at reducing the quantity of silt being eroded off farmland into the rivers - after all it is a first principle in addressing pollution control to deal with SOURCE before PATHWAY and finally RECEPTOR. Catchment Sensitive Farming initiatives aim to help farmers with this, but the initiative is inadequately funded (our R Frome initaitive is to be put into ''passive" status owing to inadequate funding) with CSF "struggling" to deliver.

In all the years I have been working in land management, many daft things have been done to floodplains and high up on the list is the conversion of permanent pasture to temporary grassland or, worse still, arable land in areas which should NEVER have been ploughed. One of the daftest examples was the construction of an embankment within part of the Nene Washes (Cambs) within which the land was pumped and carrots grown (the water being pumped on to adjacent land, making that wetter!) The Washes were designed to TAKE AND HOLD FLOODWATER and should never have been used to grow arable crops. This daftness was eventually put into reverse, but Tory MP Richard Body was one of many commentators who raised the profile about this type of mad subsidy-driven farming in his books Agriculture: The Triumph and the Shame and Farming in the Clouds. Subsidy-driven deep drainage for farming intensification in the Somerset Levels was also a cause celebre in the 1980s - and why the Environmentally Sensitive Areas Scheme was introduced here (following Andrew Lee's and other's campaigns about wetland destruction in the Halvergate Marshes and other areas). It is a tragedy that the ESA scheme is no more and a big concern that farmers could now drop out of the agri-environment programme, with the risk that land could be, once more, cultivated and intensified here.

It is urgent that questions should be asked about what types of land use are appropriate to the Levels. Resilient pastures are floristically diverse, with many grass and herb species that can tolerate prolonged flooding, unlike re-seeded rye-grass leys or arable land. Listening to one farmer who had just re-seeded after last winter reinforces the need to look at just what is grown on the levels and how farming can become more resilient there. Another farmer was on the radio saying he had lost a winter wheat crop. So why is winter wheat being grown on land liable to flooding - it doesn't make sense unless you are willing to take a big gamble (and lose the crop)? Arable land on the Levels also offers a potential and much greater source of silt, than does permanent pasture, that will end up in the rivers (and thus increase the frequency for river-dredging). All these considerations must be part of the big debate about future management of the Levels. Finally, any funding from the public sector must be strongly justified. We keep being reminded we are in an age of austerity and Somerset is facing a situation where cuts in public services are deep and damaging. As a taxpayer I want to see my taxes used to protect people and property where this makes sense, but not to justify the continuation of inappropriate land use practices that are going to make matters worse.

  1. Nice Post...Many homes in high risk flood zones have significant structural issues. Although the structural issues may be able to be repaired, raising your home may be the best option to insure the longevity and safety to your home. Many structural issues are not completely apparent to the untrained eye and homeowners need professional evaluation and advice. Raising your home and repairing all structural issues may be necessary to prevent future problems.Read about House Raising Texas
