Environmental groups warn of dredging ‘triple whammy’ with damage to wildlife, increased flooding and legal challenges

Friday 19th July 2013

The Blueprint for Water coalition of environmental organisations has this week submitted a strong response to the Government, objecting to proposals to weaken controls on river dredging which have been produced at the request of Environment Secretary Owen Paterson.

The Environment Agency was asked by Mr Paterson to consider how it can make it easier for farmers and landowners to undertake their own dredging and watercourse maintenance, in response to some strong lobbying by the National Farmers Union in the aftermath of last year’s heavy rainfall and flooding.

The Agency now proposes to deregulate parts of the consenting process for dredging through the use of a Regulatory Position Statement (RPS) that would enable farmers and landowners to undertake works themselves. The Blueprint for Water coalition believes that this move runs contrary to the EA’s own advice on the use of dredging as a flood control measure and is concerned that the deregulation could herald a return to the river management regimes of the 1960s and 70s. This was a time when rivers were dredged and straightened and when valuable habitat was destroyed in the mistaken belief that moving floodwater downstream at a faster rate would reduce flood risk. In fact studies have shown that at best, dredging is often ineffective.  At worst, it can create heavier flooding by increasing the height of the peak flows.

Dredging river channels doesn't make them big enough to contain the huge volumes of water during a flood... Even major dredging will not free up enough space in the river channel

Worryingly, Mr Paterson is reported as telling the South West Agricultural Conference in April this year that, ‘The purpose of waterways is to get rid of water.’

The Environment Agency’s own guide to Dredging and Flood Risk states:

Dredging river channels doesn't make them big enough to contain the huge volumes of water during a flood. When a major flood occurs, water soon fills the river and enters what we call the 'floodplain'. The floodplain is an area of land over which water naturally flows during flooding. Even major dredging will not free up enough space in the river channel to stop this from happening.’

In its response to the RPS the Blueprint coalition said: ‘We do not believe that a return to ad-hoc and uncoordinated river “maintenance” has a role to play in the future.  Such a move is diametrically opposed to the spirit of the Catchment Based Approach launched by Richard Benyon in June this year (which will see coordinated action at a local level to improve the health of our river systems), and it risks causing significant environmental damage and exacerbating flooding impacts in downstream communities.

Wetland wildlife is in crisis, despite the range of legislation designed to protect and enhance it.  We understand the difficulties that heavy rainfall events bring for farmers and for food production.  However, data from the Environment Agency suggests widespread non-compliance with legislation is at the root of many of the runoff and siltation problems facing our rivers and wetlands. We are concerned that the RPS proposal relaxes controls further and, in doing so reinforces the view that environmental protection is a burden that can be ignored at will, rather than a tool that actually helps control flooding and protects our natural heritage and wildlife for the benefit of all.’

The Blueprint coalition has also warned of potential legal challenges and consequent risks for landowners adding: ‘We have concluded that the proposal set out in the RPS will, at best, maintain the status quo. It is more likely, however, to pose a significant threat to the natural environment, to compromise domestic and European obligations and put landowners at risk of inadvertently falling foul of legal requirements.’

The Blueprint for Water coalition outright objects to the proposed content and trialling of the RPS; instead, it suggests that the government should consider piloting an improved fast track consenting process designed to reduce unnecessary red tape while keeping in place existing environmental protections and controls. The coalition also suggested Government should work with farmers to improve soil and land management to stop soils from washing into rivers into the first place, and should ensure that the flooding of agricultural land is addressed at catchment scale, with a thorough assessment of the causes and development of sustainable solutions.

Carrie Hume, Chair of the Blueprint for Water coalition says:

The reduction in dredging activity by organisations such as the Environment Agency reflects the growing recognition that it just isn’t an effective way of preventing large-scale flooding. We’re sure that the farming community will see through the Government’s ‘offer’ which will allow them to undertake - at their own cost and risk - an activity which in the majority of cases is likely to see more flooding, not less, and fewer and fewer places with a healthy river environment. This is a very short-sighted way to deal with calls for action.

The Government is in danger of creating the triple whammy of a ‘lawyer’s charter’ as well as long term environmental damage and increased flood risk.  Common sense must tell them that there is better way.’
