I agree with Ninthace that the attitudes expressed in the previous outbursts are too extreme, but his response is so placatory, as to be alarming, and too often expressed by the users of the countryside.
The land is a resource and as leisure is an increasing social and economic user of that resource, the occupiers, who cultivate, crop and raise livestock on that part of this resource that is soil must start to move with the times and realize that they each occupy a small part of the countryside that forms the entity that the leisure user needs.
An out date notion of 'freehold' has been claimed as a right by landowners, this has not been properly recognized by professional farmers, nor has the body that represents them taken on this responsibility.
Out bursts like those expressed will get more extreme if the root causes of these problems are not identified. I have tried to steer these arguments onto a more productive course, but have been criticized for this.
At a New Year's Eve dinner I was talking to a farmer's widow, she is now no longer farming and a keen golfer. There was a surprising amount of bitterness towards towards countryside visitors. She was happy to emotionally feed off such tales as related by Ninthace, her emotional animosity towards 'walkers' was surprising strong, though I don't think there had been a specific bad experience, other than perceived rudeness from local dog walkers. The root of this was money, not in lost production but the rental equivalent of outstanding mortgage and this relates into a landowner issue, because it was her sense of property that was at the core of the hostility.
What does this have to do with this topic? If there is underlying hostility, then the sympathetic understanding that should be present in Risk Assessment is possibly flawed.
If the same H&S scrutiny has been focused on these animal attacks, that most other professions and industries endure, then I think the farmers might be doing more.
If landowners were more open about sharing the countryside, then perhaps the dog walker's public nuisance might have been have been bought to book by a broader, more inclusive, countryside watch scheme.
For this to happen it is the Landowner and the Farming Lobbies, who need to become more honest. So don't go too easy on them.
