The New South Wales Farmers' Association wants the state authorities to implement moratorium on the coal seam gas industry across the region in light of the environmental risks pose by such activities.

The association unanimously declared on Tuesday that a moratorium on all mining activities in the area is necessary as they argued that "these industries are being allowed to flourish without proper concern for the threat they pose to farmland and water resources."

Association mining taskforce chair Fiona Simson clarified that the group is not countering the introduction of mining and coal seam gas development around the NSW area though she pointed out that a balance approach must be taken "when decisions are made about where development can take place."

Also, the group called on state authorities, both from the Labor and opposition politicians, to support their calls for a moratorium and devise a strategic plan for possible implementation of a transparent approvals process, independent monitoring of projects and aquifer protection.

Ms Simson said that the plan to be hatched by cross-party experts should ensure that the parameters on sleeper licenses must be strictly observed, providing enough assurance that halted mining activities would not be revived after decades of stopping their operations.

The Farmers' Association also batted for just and sufficient compensation for landholders that would be affected by the mining activities in the area.

At present, the encroachment of the coal seam gas industry in NSW has become more imminent while up to 70 percent of the state is being covered by mineral and petroleum titles and applications.

While mostly known for its wine industry, the Hunter Valley in the region is now threatened by mining activities as AGL Energy Ltd has already commenced its coal seam gas explorations in area.
