Mae’r diwydiant amaeth yn hanfodol i ddatblygu economi Cymru.  Mae rhyw 84% o dir Cymru yn dir sy’n cael ei ddefnyddio at ddibenion amaethyddol ac mae’r sector ei hun yn werth dros £150 miliwn (Gwerth Gros Ychwanegol) i economi Cymru.  Nid yw’r ffigur hwn yn agos at adlewyrchu y gwir werth y mae’n ei ychwanegu at economi Cymru ar ôl ystyried cynhyrchu bwyd, gwasanaethau amgylcheddol a buddiannau eraill a ddaw o amaethyddiaeth.
The agriculture industry is crucial to the overall development of the Welsh economy. Land used for agricultural purposes accounts for approximately 84% of the total land area in Wales and the sector alone is worth over £150 million (Gross Value Added) to the Welsh economy. This figure does not reflect anything like the full value-added to the Welsh economy when we take into account food production, environmental management services and other economic multipliers arising from agriculture.
