O dan Bolisi Amaethyddol Cyffredin yr UE, mae materion wedi codi ynghylch yr arfer lle gall dau ffermwr gwahanol hawlio taliad o dan wahanol gynlluniau ar yr un darn o dir. Ni chaniateir hawlio ddwywaith ar yr un tir o dan gynllun Glastir a fydd yn weithredol o 1 Ionawr 2012.
Under the EU Common Agriculture Policy issues have arisen about the practice whereby two different farmers are able to claim payment under different schemes on the same piece of land. This dual use of land is not permitted under the Glastir scheme that will be operational from 1 January 2012.
