Er mwyn cyflawni uchelgeisiau sero net Llywodraeth Cymru, mae angen i Gymru leihau ei hallyriadau amaethyddol drwy newidiadau i arferion ffermio a mwy o atafaeliad carbon, tra hefyd yn cynnal bywoliaethau gwledig.<\/p>\n
Mae Canolfan Polisi Cyhoeddus Cymru (WCPP) wedi cael cyllid gan Lywodraeth Cymru i ddarparu cymorth annibynnol i Gr\u0175p Her Sero Net Cymru 2035, dan gadeiryddiaeth y cyn-weinidog Jane Davidson, i\u2019w helpu i gael gafael ar dystiolaeth ac arbenigedd perthnasol i lywio eu gwaith.<\/p>\n
Mae maes her gyntaf y Gr\u0175p yn gofyn \u2018Sut y gallai Cymru fwydo\u2019i hun yn 2035?\u2019 gan ganolbwyntio ar system fwyd sy\u2019n gallu cyflawni sero net yn ogystal ag uchelgeisiau Deddf Llesiant Cenedlaethau\u2019r Dyfodol.<\/p>\n
Mae pecyn tystiolaeth WCPP yn cyflwyno trosolwg o ddata allweddol a thueddiadau sy\u2019n ymwneud \u00e2 system fwyd Cymru, yn ogystal \u00e2 phapur trafod sy\u2019n cyfuno\u2019r dystiolaeth bresennol ar systemau bwyd, amaethyddiaeth a defnydd tir. Fe\u2019i paratowyd i ysgogi trafodaeth ymhlith y Gr\u0175p ac nid yw\u2019n ceisio darparu unrhyw farn nac argymhellion pendant i\u2019r Gr\u0175p eu cymeradwyo.<\/p>\n
Yn senario \u2018llwybr cytbwys\u2019 Pwyllgor Newid Hinsawdd y DU i Gymru gyrraedd sero net erbyn 2050, amaethyddiaeth fydd y ffynhonnell allyriadau fwyaf erbyn 2035 wrth i sectorau eraill ddatgarboneiddio\u2019n gyflymach. Er mwyn cyrraedd sero net, bydd angen defnyddio tir sy\u2019n cael ei ddefnyddio ar hyn o bryd ar gyfer cynhyrchu amaethyddol ar gyfer dal a storio carbon: mae tystiolaeth yn awgrymu y bydd cymysgedd o ddulliau rhannu tir a dulliau arbed tir yn caniat\u00e1u ar gyfer gostyngiadau mewn allyriadau tra hefyd yn cefnogi ffermwyr Cymru. Bydd lleihau allyriadau amaethyddol hefyd yn gofyn am ostyngiad yn nifer y da byw, oherwydd ar eu pen eu hunain, ni fydd newidiadau eraill i arferion ffermio presennol yn mynd yn ddigon pell. Felly, mae angen dod o hyd i ffyrdd amgen o gynnal bywoliaethau gwledig ar wah\u00e2n i bori da byw, yn enwedig ar y 79% o dir Cymru sy\u2019n llai addas ar gyfer tyfu cnydau.<\/p>\n
Yn ogystal \u00e2 lleihau allyriadau o gynhyrchu, bydd cyrraedd sero net hefyd yn gofyn am ostyngiadau mewn allyriadau defnydd, trwy newidiadau mewn deiet a gostyngiadau mewn gwastraff bwyd a phecynnu. Gallai lleihau faint o gig a chynnyrch llaeth a fwyteir a chynyddu mynediad at fwyd iach, fforddiadwy ac o ffynonellau lleol fod ag amrywiaeth o fanteision: mae Swyddog Ymchwil WCPP, Greg Notman, wedi cyhoeddi blog yn archwilio\u2019r manteision hyn.<\/p>\n
Mae\u2019r dadansoddiad a\u2019r casgliadau a gyflwynir yn yr adroddiad, y blog a\u2019r darn trafod yn eiddo i\u2019r awduron ac nid ydynt yn cynrychioli barn na safbwyntiau Gr\u0175p Her Sero Net Cymru 2035.<\/p>\n
