Planning officers and governments issuing guidance need to be positive about changes, including rural housing and diversified activities. There have been failures in both the public and the private sectors. I recall policies which involved grants for preserving hedges while at the same time assisting their grubbing out. That was not many years ago. Land managers may have sinned but I suspect that it is mostly in pursuit of Government and EU policy.
Partnership is a current buzz word.
All I will say is that partners share costs, risks and investment culture. They have compatible and transparent agendas. And I have a word about management plans. Often those have different meanings for different people. They should never be compulsory, even less the sole means of providing incentives or grants.
