The Farmers' Union of Wales says Welsh Government water quality legislation makes a mockery of devolution by failing to address Welsh concerns and needs.

The legislation will mean the phasing across Wales of what are effectively EU rules currently in place in intensively farmed areas -  designate the whole of Wales as an EU Nitrate Vulnerable Zone (NVZ), an area more than forty times bigger than the current Welsh NVZ area, and eleven times bigger than what was recommended by NRW.

FUW president Glyn Roberts said: "The blank sheet of devolution and Brexit allows Welsh Government to design a bespoke system which would target problem areas without being disproportionate and costing the farming industry hundreds of millions - including in areas where there are no problems.

"This was precisely the recommendation of NRW, the FUW and others in a report presented to Welsh Government in 2018."

Mr Roberts said that instead the Welsh Government has taken the draconian and unimaginative move of taking off-the-shelf regulations and applying them for the whole of Wales.

"As with the current white paper proposals for agricultural support, which simply copies a Defra plan, this announcement makes a mockery of devolution, and marks a betrayal of the principles of evidence-based decision making," added Mr Roberts.

NRW had previously advised the Welsh Government against implementing the legislation, warning it could have the perverse outcome of making pollution worse, while also warning of the severe resource implications of such a draconian move.

"It is now essential that members of the senedd stand up for what is best for Wales as this legislation is considered, rather than adding to the erosion of devolution that this legislation symbolises," said Mr Roberts.
