FEARS are mounting in Pembrokeshire as a potentially huge expansion of nitrate vulnerable zones (NVZ) remains under consultation.
Farmers Union of Wales (FUW) said the plans were causing huge anxiety among many farmers in West Wales.
The consultation regarding the Cleddau Rivers catchment and the Milford Haven waterway could see the introduction of an NVZ which would affect up to 2,000 farms in an area which provides half of the Welsh potato crop and a quarter of its milk.
FUW senior policy officer Dr Hazel Wright said: “The FUW has devoted many days of work to the NVZ issue in Pembrokeshire and meetings are being held on an almost weekly basis.
“Given the severe repercussions of NVZ designation for farmers, the focus must be to minimise the area designated under the regulations while finding solutions for those within areas which are designated, including through best use of RDP funding.
“The threat of NVZ designation could not come at a worse time given the collapse in farmgate prices and there being little hope of an improvement in European and global dairy markets.”
