Rhagor o oedi...<\/strong><\/h3>\n

 <\/p>\n

Yr wythnos diwethaf, datgelodd Llywodraeth Cymru y cynllun i weithredu argymhellion Dr. Bolton. Yn anffodus, roedd y cynllun yn manylu ar ragor o oedi, yn enwedig wrth weithredu\u2019r newidiadau hynny a allai wneud gwahaniaeth gwirioneddol i\u2019n hafonydd.<\/p>\n

Ac i ffermwyr, mae\u2019r oedi ychwanegol hyn yn broblem hefyd. Cafodd llawer o\u2019r argymhellion eu cynllunio i\u2019w helpu i gydymffurfio \u00e2\u2019r rheoliadau ar reoli llygredd amaethyddol.\u00a0<\/p>\n

Roedd argymhelliad cyntaf Dr. Bolton ar gyfer y tymor byr yn sefydlu \u2018gr?p technegol tasg a gorffen\u2019. Mae ei ffurfio bellach ar y gweill.\u00a0<\/p>\n

Mae\u2019r 22 argymhelliad arall wedi\u2019u cynllunio mewn tair cam:<\/p><\/div>\n\t\t\t<\/div>

Cam 1<\/h3>\n

Bydd hyn yn digwydd dros y 12\u201318 mis nesaf ac yn cynnwys 6 argymhelliad.<\/span>\u00a0<\/p>\n

Fodd bynnag, mae llawer o\u2019r cam hwn yn canolbwyntio ar leddfu\u2019r baich ar y rheoliadau ar ffermwyr. Yr unig argymhelliad sy\u2019n mynd i\u2019r afael \u00e2 llygredd amaethyddol mewn gwirionedd yw cynnwys mesurau i ddiogelu rhag colli pridd.\u00a0<\/p>\n

Yr hydref hwn, mae rhannau helaeth o gefn gwlad Cymru unwaith eto wedi\u2019u hamlygu i risg uchel o lifogydd oherwydd arferion rheoli tir gwael, megis plannu indrawn a chnydau porthiant mewn lleoliadau amhriodol.\u00a0<\/p>\n

Ni all rheoliadau cryfach ar briddoedd ddod yn ddigon buan, ond hyd yn oed os daw hynny mewn 12 mis (y cynharaf yn \u00f4l Llywodraeth Cymru), bydd yn rhy hwyr i ddiogelu silio eogiaid a sewin y gaeaf hwn ac, yn \u00f4l pob tebyg, silio\u2019r flwyddyn nesaf hefyd. Mae\u2019r rhywogaethau hyn angen gweithredu brys os yw\u2019r cwympiadau pryderus yn eu niferoedd i gael eu gwrthdroi.<\/p><\/div>\n\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t\n\t\t\t<\/div>

Gwelliannau ar fin digwydd mewn afonydd yn annhebygol<\/h3>\n

Gallai\u2019r oedi wrth ddatrys llygredd amaethyddol, ynghyd \u00e2 datganiad diweddar y Dirprwy Brif Weinidog y bydd newidiadau i reoleiddio\u2019r diwydiant d?r yn cymryd hyd at 7 mlynedd, olygu ei bod yn annhebygol y gwelwn unrhyw welliant ar unwaith yn ansawdd d?r afonydd Cymru.<\/span><\/p>\n

\u00a0Os bydd gwelliant, mae\u2019n debygol na fydd hynny oherwydd polisi\u2019r Llywodraeth ond yn hytrach oherwydd gweithredu gan ffermwyr unigol yng Nghymru sy\u2019n deall goblygiadau colli pridd i\u2019w busnesau ac sy\u2019n gofalu am afonydd.<\/p><\/div>\n\t\t\t<\/div>

Nid oes prinder tystiolaeth fod amaethyddiaeth yn llygru afonydd Cymru. Mae Cyfoeth Naturiol Cymru bellach yn meddu ar dystiolaeth fod y sector yn effeithio ar safleoedd morol gwarchodedig Cymru hefyd.<\/p>\n

Gall olwynion y Llywodraeth droi\u2019n araf. Ond mae angen gweithredu mesurau Dr Bolton ar gyflymder os ydym o ddifrif am ddatrys y problemau eang sy\u2019n effeithio ar ansawdd d?r, bioamrywiaeth a dirywiad rhywogaethau fel eog yr Iwerydd yng Nghymru.<\/p>\n

Mae\u2019n debygol mai\u2019r gr?p tasg a gorffen fydd yr unig un o\u2019r argymhellion a weithredir yn llawn cyn etholiadau\u2019r Senedd y gwanwyn nesaf, dros flwyddyn ers y adroddiad.<\/p>\n

Er gwaethaf cynnydd rhewlifol, efallai mai\u2019r agwedd fwyaf pryderus yw nad oes unrhyw sicrwydd, pa Lywodraeth Cymru bynnag ddaw nesaf, y bydd newidiadau i wella rheolaeth rheoliadau llygredd amaethyddol yn derbyn yr un math o ymrwymiad a roddwyd gan y Dirprwy Brif Weinidog presennol, nac y bydd eu gweithredu\u2019n cyflymu.<\/p><\/div>\n\t\t\t<\/div>
