English: These tests should have been carried out by the planning authority when the development plan was prepared and the acceptable uses for the site identified.
Welsh: Dylai'r awdurdod cynllunio fod wedi cynnal y profion hyn adeg paratoi'r cynllun datblygu a nodi defnyddiau derbyniol ar gyfer y safle.
English: However, there may be instances where the nature of the proposal is not adequately addressed by the development plan and it may be appropriate to apply one or more of these tests.
Welsh: Fodd bynnag, mewn rhai achosion mae'n bosibl na fydd y cynllun datblygu yn rhoi sylw digonol i'r cynnig, a gall fod yn briodol defnyddio un neu fwy o'r profion hyn.
English: Planning authorities should anticipate such changes using appropriate conditions
Welsh: Dylai awdurdodau cynllunio ragweld newidiadau o'r fath drwy ddefnyddio amodau priodol
English: Conditions can restrict the amount of floorspace, or prevent a development from being sub-divided into smaller shops to limit the range of goods sold, or prevent the creation of a single large store.
Welsh: Gall amodau gyfyngu ar faint yr arwynebedd llawr, neu atal datblygiad rhag cael ei isrannu'n nifer mawr o siopau bach er mwyn cyfyngu ar yr amrywiaeth o nwyddau a werthir, neu atal y broses o greu un siop fawr.
English: Also where the inclusion, for instance, of post offices and pharmacies in out-of-centre retail developments would be likely to lead to the loss of existing provision in a designated retail and commercial centre, they should be discouraged by imposing appropriate conditions.
Welsh: Hefyd, pe byddai cynnwys swyddfeydd post a fferyllfeydd, er enghraifft, mewn datblygiadau manwerthu y tu allan i ganolfannau yn debygol o arwain at golli'r ddarpariaeth sy'n bodoli eisoes mewn canolfan fanwerthu a masnachol dynodedig, dylid annog datblygwyr i beidio â chyflwyno cynigion o'r fath drwy osod amodau priodol.
English: Planning authorities may wish to consider extending the list of uses controlled in out-of-centre retail developments if the location of such uses are likely to lead to the loss of existing provision in retail and commercial centres.
Welsh: Gallai awdurdodau cynllunio ystyried estyn y rhestr o ddefnyddiau a reolir mewn datblygiadau manwerthu y tu allan i ganolfannau os yw lleoliad defnyddiau o'r fath yn debygol o arwain at golli darpariaeth sy'n bodoli eisoes mewn canolfannau manwerthu a masnachol.
English: Applications to remove or vary conditions should be subject to the same considerations.
Welsh: Dylid rhoi'r un ystyriaeth i geisiadau i ddileu neu amrywio amodau o'r fath.
English: Mixed Uses and Primary and Secondary
Welsh: Defnyddiau Cymysg a Phrif Ardaloedd Siopa ac Ardaloedd Siopa Eilaidd
English: Secondary areas typically contain mixed uses, for example shops, cafes and restaurants, financial establishments and other services and community facilities.
Welsh: Fel arfer, mae ardaloedd siopa eilaidd yn cynnwys defnyddiau cymysg, er enghraifft, siopau, caffis a bwytai, sefydliadau ariannol a gwasanaethau eraill a chyfleusterau cymunedol.
English: Planning authorities should identify which retail and commercial centres in their development plans have primary and secondary shopping areas, and show these on the proposals map.
Welsh: Dylai awdurdodau cynllunio nodi pa ganolfannau manwerthu a masnachol yn eu cynlluniau datblygu sydd â phrif ardaloedd siopa ac ardaloedd siopa eilaidd, a'u dangos ar y map cynigion.
English: Development plans should include policies describing the types of use that are likely to be acceptable in primary and secondary areas.
Welsh: Dylai cynlluniau datblygu gynnwys polisïau sy'n disgrifio'r mathau o ddefnydd sy'n debygol o fod yn dderbyniol mewn prif ardaloedd siopa ac ardaloedd siopa eilaidd.
English: In addition to general diversity of uses, mixed use developments, which combine retailing with entertainment, restaurants and, where appropriate, residential in a comprehensive and planned way should also be encouraged where appropriate to promote lively centres during both the day and the evening.
Welsh: Yn ogystal ag amrywiaeth gyffredinol o ddefnyddiau, dylid hefyd annog datblygiadau defnydd cymysg, sy'n cyfuno manwerthu ag adloniant, bwytai a, lle bo hynny'n briodol, preswyl mewn ffordd gynhwysfawr a gynlluniwyd, er mwyn hyrwyddo canolfannau bywiog yn ystod y dydd a gyda'r nos.
English: Where the right balance of use and activity is not being achieved, planning authorities should consider making changes to the acceptable uses in primary or secondary areas, or the retail and commercial centre boundaries themselves.
Welsh: Os nad oes modd sicrhau cydbwysedd priodol rhwng defnydd a gweithgareddau, dylai awdurdodau cynllunio ystyried gwneud newidiadau i'r defnyddiau derbyniol mewn prif ardaloedd neu ardaloedd eilaidd, neu i ffiniau'r ganolfan fanwerthu a masnachol.
English: They should use the strategy in their development plan to manage change and take action where necessary to address this.
Welsh: Dylent ddefnyddio'r strategaeth yn eu cynllun datblygu i reoli newid a gweithredu os oes angen mynd i'r afael â hyn.
English: Where economic decline is impacting on a retail and commercial centre, emphasis on retaining A1 uses in premises either in primary or secondary areas, which have been vacant for a period of time, may undermine a centre's viability and vitality.
Welsh: Os yw dirywiad economaidd yn effeithio ar ganolfan fanwerthu a masnachol, gallai pwyslais ar gadw defnyddiau A1 mewn eiddo naill ai mewn prif ardal neu ardal eilaidd, a fu'n wag am gyfnod o amser, danseilio hyfywedd a bywiogrwydd canolfan.
English: Technical Advice Note 4, Retail and Commercial Development, Welsh Government, 2016. https://gov.wales/topics/planning/policy/tans/tan4/?lang=en
Welsh: Nodyn Cyngor Technegol 4: Datblygiad Manwerthol a Masnachol. Llywodraeth Cymru 2016
English: Rationalising a centre's boundary can help concentrate both A1 and non-A1 uses in a smaller more viable area, whilst potentially releasing property outside the new boundary for residential and other appropriate uses.
Welsh: Gall ad-drefnu ffin canolfan helpu i ganolbwyntio defnyddiau A1 a defnyddiau nad ydynt yn A1 mewn ardal lai o faint ond mwy hyfyw, gan ryddhau eiddo y tu allan i'r ffin newydd o bosibl at ddibenion preswyl a dibenion priodol eraill.
English: Within a retail and commercial centre boundary change of use to residential may also be acceptable and help contribute to the viability and vibrancy of a centre.
Welsh: Gall newid defnydd i ddefnydd preswyl hefyd fod yn dderbyniol o fewn ffiniau canolfan fanwerthu a masnachol, gan helpu i gyfrannu at hyfywedd a bywiogrwydd canolfan.
English: However, night-time noise considerations may be a limiting factor in some areas and residential use is unlikely to be suitable on the ground floor within primary areas or other places of concentrated A1 uses because it may fragment the shopping frontage and impact on the vibrancy and viability of a centre.
Welsh: Fodd bynnag, mae'n annhebygol y bydd defnydd preswyl yn addas ar loriau gwaelod mewn prif ardaloedd neu feysydd A1 crynodedig eraill, oherwydd gall ddarnio ffryntiad siopau ac effeithio ar fywiogrwydd a hyfywedd canolfan.
English: This should be done through full consultation with communities as part of the development plan.
Welsh: Dylid gwneud hynny drwy ymgynghori'n llawn â chymunedau fel rhan o'r cynllun datblygu.
English: Such management, involving enhancement and promotion, can be an important factor in achieving vibrancy, viability, and attractiveness in retail centres.
Welsh: Gall rheolaeth o'r fath, sy'n cynnwys gwella a hyrwyddo, fod yn ffactor pwysig wrth sicrhau bywiogrwydd, hyfywedd, a dengarwch canolfannau manwerthu.
English: Management measures can also contribute to the achievement of a safe and crime free environment.
Welsh: Gall mesurau rheoli hefyd gyfrannu at sicrhau amgylchedd diogel lle nad oes unrhyw droseddu.
English: Partnership between local authorities and the private sector is essential to the success of such management strategies.
Welsh: Mae partneriaeth rhwng awdurdodau lleol a'r sector preifat yn hanfodol i lwyddiant strategaethau rheoli o'r fath.
English: Local and Village Shops
Welsh: Siopau Lleol a Siopau Pentref
English: In rural areas, planning authorities should adopt a positive approach to applications for conversion of suitable
Welsh: Mewn ardaloedd gwledig, dylai awdurdodau cynllunio fabwysiadu agwedd gadarnhaol at geisiadau i addasu eiddo addas mewn pentrefi yn siopau ac am estyniadau i siopau pentref sydd â'r bwriad o wella eu hyfywedd.
English: village properties to shops and for extensions to village shops designed to improve their viability. A positive approach should also be taken, subject to amenity considerations, to reestablishing public houses, especially in villages which have lost such provision.
Welsh: Dylid mabwysiadu agwedd gadarnhaol hefyd, yn amodol ar ystyriaethau amwynderau, at ailsefydlu tafarndai yn enwedig, mewn pentrefi sydd wedi colli darpariaeth o'r fath yn gyfan gwbl.
English: The lack of public transport in rural areas should not preclude small-scale retail or service development where this will serve local needs.
Welsh: Ni ddylai diffyg trafnidiaeth gyhoeddus mewn ardaloedd gwledig atal datblygiadau manwerthu neu wasanaethau ar raddfa fach os bydd hynny'n gwasanaethu anghenion lleol.
English: In assessing such proposals, Planning Authorities should take account of:
Welsh: Wrth asesu cynigion o'r fath, dylai Awdurdodau Cynllunio ystyried:
English: the potential impact on nearby retail and commercial centres or village shops;
Welsh: yr effaith bosibl ar ganolfannau manwerthu a masnachol neu siopau pentref cyfagos;
English: the desirability of providing a service throughout the year;
Welsh: pa mor ddymunol fyddai darparu gwasanaeth drwy gydol y flwyddyn;
English: the likely impact of traffic generated and access and parking arrangements.
Welsh: effaith debygol y traffig a gaiff ei greu a threfniadau mynediad a pharcio.
English: The Importance of Evening and Night Time Economies
Welsh: Pwysigrwydd Economïau Gyda'r Nos a'r Nos
English: Such uses may include, for example, bars, restaurants, pubs, theatres, music, arts and other entertainment venues which provide for social and cultural experience and spaces in which creativity can be fostered.
Welsh: Gall defnyddiau o'r fath gynnwys barrau, bwytai, tafarndai, theatrau, cerddoriaeth, celf a lleoliadau adloniant eraill sy'n darparu profiad cymdeithasol a diwylliannol a gofodau lle mae modd meithrin creadigrwydd.
English: Such activities are likely to be characterised by increased levels of noise, large gatherings of people, later operating hours and greater movements in traffic.
Welsh: Nodweddion tebygol gweithgareddau o'r fath yw lefelau uwch o sŵn, grwpiau mawr o bobl yn ymgynnull, oriau agor hwyrach a mwy o symud o ran traffig.
English: Similarly where residential development is proposed next to or near existing evening and night time uses, such as those described, it will be necessary to consider the compatibility of uses and to incorporate mitigation measures to minimise any impact on the amenity of any future residents.
Welsh: Yn yr un modd, os yw datblygiad preswyl yn cael ei gynnig wrth ymyl neu gerllaw defnyddiau presennol gyda'r nos neu yn y nos, fel y rhai a ddisgrifiwyd, bydd angen ystyried cydnawsedd y defnyddiau a chynnwys mesurau lliniaru er mwyn lleihau unrhyw effaith ar amwynder unrhyw ddarpar breswylwyr.
English: The agent of change principle (see Chapter 6 for more detail) will be a guiding principle for supporting the evening economy and the development of uses sensitive to the soundscapes experienced in busy commercial centres.
Welsh: Defnyddir yr egwyddor cyfrwng newid (gweler Pennod 6 am fwy fanylion) yn sylfaen i gefnogi economi gyda'r nos a datblygu defnyddiau sy'n sensitif i seinweddau canolfannau masnachol prysur.
English: These 'quarters' help create further vibrancy and diversity that stimulates wider growth and regeneration.
Welsh: Mae'r mannau hyn yn helpu i greu rhagor o fywiogrwydd ac amrywiaeth sy'n sbarduno twf ac adfywio ehangach.
English: Traditionally, such hubs grow from the ground up with local and national government playing an enabling role.
Welsh: Yn draddodiadol, mae canolfannau o'r fath yn tyfu o'r gwaelod i fyny, ac mae llywodraeth leol a'r llywodraeth ganolog yn cyflawni swyddogaeth galluogi bwysig.
English: There is evidence that these quarters often evolve from quite humble origins utilising cheap, often disused, building spaces.
Welsh: Mae tystiolaeth yn dangos bod y canolfannau hyn yn esblygu o wreiddiau cymharol gyffredin yn aml, gan ddefnyddio adeiladau rhad sy'n wag yn aml.
English: Community facilities contribute to a sense of place which is important to the health, well-being and amenity of local communities and their existence is often a key element in creating viable and sustainable places.
Welsh: Mae cyfleusterau cymunedol yn cyfrannu at ymdeimlad o le sy'n bwysig ar gyfer iechyd, llesiant ac amwynder cymunedau lleol, ac yn aml mae eu bodolaeth yn elfen allweddol o greu lleoedd hyfyw a chynaliadwy.
English: They can include schools, cultural facilities, health services, libraries, allotments and places of worship.
Welsh: Gallant gynnwys ysgolion, cyfleusterau diwylliannol, gwasanaethau iechyd, llyfrgelloedd, rhandiroedd ac addoldai.
English: When considering development proposals planning authorities should consider the needs of the communities and ensure that community facilities continue to address the requirements of residents in the area.
Welsh: Wrth ystyried cynigion datblygu, dylai awdurdodau cynllunio ystyried anghenion cymunedau a sicrhau bod cyfleusterau cymunedol yn parhau i fodloni gofynion trigolion yn yr ardal.
English: They can contribute to a place's identity and its sense of community, and can help to regenerate open spaces.
Welsh: Gallant gyfrannu at hunaniaeth lle a'i ymdeimlad o gymuned, gan helpu i adfywio mannau agored.
English: Local authorities should retain and protect existing allotment sites, particularly where they have an important green infrastructure or community value.
Welsh: Dylai awdurdodau lleol gadw a diogelu safleoedd rhandiroedd presennol, yn enwedig os ydynt yn bwysig fel seilwaith gwyrdd neu ased cymunedol.
English: Where there is demonstrable demand, local authorities have a statutory duty to provide land for allotments.
Welsh: Os oes galw hysbys amdano, mae gan awdurdodau lleol ddyletswydd statudol i ddarparu tir ar gyfer rhandiroedd.
English: Where appropriate, plans should allocate land for new allotments and community growing spaces.
Welsh: Lle y bo'n briodol, dylai cynlluniau neilltuo tir ar gyfer rhandiroedd a mannau tyfu cymunedol newydd.
English: Statutory allotments have legal protection.
Welsh: Mae rhandiroedd statudol yn cael eu diogelu gan y gyfraith.
English: They cannot be sold or used for other purposes without the consent of the Welsh Ministers.
Welsh: Ni allant gael eu gwerthu na'u defnyddio at ddibenion eraill heb gydsyniad Gweinidogion Cymru.
English: They provide a place for play, sport, healthy physical activity and a place to relax often in the presence of nature, and they contribute to our quality of life.
Welsh: Maent yn darparu lleoedd ar gyfer chwarae, chwaraeon, gweithgarwch corfforol iach a lle i ymlacio yng nghanol byd natur yn aml, gan gyfrannu at ein hansawdd bywyd.
English: Networks of high quality, accessible green spaces and recreation spaces will also promote nature conservation, biodiversity and provide enjoyable opportunities for residents and visitors to participate in a wide range of physical activities.
Welsh: Bydd rhwydweithiau o ansawdd uchel, mannau gwyrdd hygyrch a mannau hamdden yn hyrwyddo cadwraeth natur a bioamrywiaeth hefyd ac yn darparu cyfleoedd pleserus i drigolion ac ymwelwyr gymryd rhan mewn ystod eang o weithgareddau corfforol.
English: These activities are important for the well-being of children and adults and for the social, environmental, cultural and economic life of Wales.
Welsh: Mae'r gweithgareddau hyn yn bwysig i lesiant plant ac oedolion a bywyd cymdeithasol, amgylcheddol, diwylliannol ac economaidd Cymru.
English: These policies should set standards of provision, so that local deficiencies can be identified and met through the planning process, and set out policies to avoid or resolve conflict between different activities.
Welsh: Dylai'r polisïau hyn bennu safonau ar gyfer y ddarpariaeth, fel bod modd nodi ac unioni diffygion lleol drwy'r broses gynllunio, a llunio polisïau i osgoi neu ddatrys gwrthdaro rhwng gweithgareddau gwahanol.
English: Such open spaces also have a role in climate protection and in enabling the adaptation of urban areas to the impacts of climate change, for example by contributing to flood management and helping to reduce the effects of urban heat islands.
Welsh: Mae gan fannau agored o'r fath rôl i'w chwarae hefyd yn diogelu'r hinsawdd ac yn galluogi ardaloedd trefol i ymaddasu i effeithiau'r newid yn yr hinsawdd, er enghraifft drwy gyfrannu at reoli llifogydd a helpu i leihau effeithiau ynysoedd gwres trefol.
English: Many parks and gardens are historically significant and are listed in the Historic Parks and Gardens in Wales Register.
Welsh: Mae parciau a gerddi yn hanesyddol bwysig ac maent wedi'u rhestru yng Nghofrestr Parciau a Gerddi Hanesyddol Cymru.
English: facilities can best be retained and enhanced through the redevelopment of a small part of the site;
Welsh: lle y gellir cadw a gwella cyfleusterau orau drwy ailddatblygu rhan fach o'r safle;
English: alternative provision of equivalent community benefit is made available locally, avoiding any temporary loss of provision;
Welsh: lle y darperir darpariaeth arall yn yr ardal o'r un budd i'r gymuned, gan osgoi colli'r ddarpariaeth dros dro;
English: there is an excess of such provision in the area.
Welsh: lle y mae gormod o ddarpariaeth o'r fath yn yr ardal.
English: They should indicate the ways in which previously developed or disused land and water bodies can be used for sport and recreation uses, particularly in relation to urban regeneration.
Welsh: Dylent nodi sut y gellir defnyddio tir neu gyrff dŵr a ddatblygwyd o'r blaen, neu dir neu gyrff dŵr segur, at ddibenion chwaraeon a hamdden, yn enwedig yng nghyd-destun adfywio trefol.
English: Where recreational use of redundant railway lines or spaces alongside canals or rivers is proposed, planning authorities should ensure that there is no detriment to adjoining users, wildlife or flood defences.
Welsh: Os cynigir defnyddio llinellau rheilffyrdd segur neu fannau ar hyd camlesi neu afonydd at ddibenion hamdden, dylai awdurdodau cynllunio sicrhau nad yw hyn yn cael effaith niweidiol ar ddefnyddwyr neu fywyd gwyllt cyfagos, neu ar amddiffynfeydd rhag llifogydd.
English: Places which are productive and enterprising contribute to the seven goals of the Well-being of Future Generations Act which include:
Welsh: Mae lleoedd sy'n gynhyrchiol a mentrus yn cyfrannu at saith nod Deddf Llesiant Cenedlaethau'r Dyfodol, sy'n cynnwys:
English: This is realised through the availability of employment land, lifelong learning and training opportunities, reliable communication networks and investment in renewable and low carbon energy sources.
Welsh: Gwireddir hyn drwy sicrhau bod tir ar gael ar gyfer cyflogaeth, cyfleoedd dysgu gydol oes a hyfforddi, rhwydweithiau cyfathrebu dibynadwy a buddsoddiad mewn ffynonellau ynni adnewyddadwy a charbon isel.
English: Resource efficient choices are promoted which have financial benefits both now and over the lifetime of development.
Welsh: Hyrwyddir dewisiadau ynni effeithlon a ddaw â manteision ariannol nawr a thros oes y datblygiad.
English: Tourism development, which can finance preservation activities, needs careful management to ensure continued enjoyment by future generations.
Welsh: Rhaid rheoli datblygiadau twristiaeth, sy'n gallu ariannu gweithgareddau cadwraeth, yn ofalus i sicrhau bod cenedlaethau'r dyfodol yn parhau i'w mwynhau.
English: Sustainable agricultural practices can also assist in nature conservation and enhancement. Wales' topography also lends itself to renewable energy generation.
Welsh: Gall arferion amaeth cynaliadwy helpu i warchod a chyfoethogi natur , Mae topograffi Cymru'n addas ar gyfer cynhyrchu ynni adnewyddadwy.
English: Greater distribution of our economic wealth can also help alleviate poverty which is a key determinant of health.
Welsh: Gallai dosrannu'n cyfoeth economaidd yn well helpu i leihau tlodi sy'n un o'r ffactorau allweddol sy'n dylanwadu ar iechyd pobl.
English: The Welsh language and culture makes a distinctive contribution to the viability of communities.
Welsh: Mae'r iaith a'r diwylliant Cymraeg a Chymreig yn gwneud cyfraniad nodedig at hyfywedd cymunedau.
English: Our tourism offer also needs promotion to capitalise support activities which reflect our distinctiveness.
Welsh: Mae angen hyrwyddo ein cynnig i dwristiaid hefyd i gynnal gweithgareddau sy'n adlewyrchu mor unigryw ydym.
English: Above all, a
Welsh: Yn anad dim, mae
English: Development proposals should look to the
Welsh: Dylai cynigion datblygu edrych tuag at y
English: Development should
Welsh: Dylai datblygiad
English: These are areas where 'larger than local' issues need to be addressed by planning authorities with the involvement of other agencies and communities to ensure sustainable outcomes are delivered across Wales.
Welsh: Mae'r rhain yn feysydd lle bo angen i awdurdodau cynllunio fynd i'r afael â ffactorau sy'n fwy na rhai lleol, hynny â chymorth asiantaethau a chymunedau eraill i sicrhau bod canlyniadau cynaliadwy'n cael eu darparu ledled Cymru.
English: Productive and Enterprising Trends and Issues
Welsh: Tueddiadau a Materion Cynhyrchiol a Mentrus
English: The breadth of topics in the Productive and Enterprising Places theme respond to future trends and issues that will need to be addressed through the planning system.
Welsh: Mae ehangder y pynciau yn y thema Lleoedd Cynhyrchiol a Mentrus yn ymateb i dueddiadau a materion y dyfodol y bydd angen mynd i'r afael â nhw drwy'r system gynllunio.
English: These trends need to be challenged by planning decisions in order to ensure we create sustainable places.
Welsh: Bydd angen i benderfyniadau cynllunio herio'r tueddiadau hyn er mwyn sicrhau ein bod yn creu mannau cynaliadwy.
English: The key issues in this theme include:
Welsh: Mae prif ystyriaethau'r thema hon yn cynnwys:
English: ensuring that there is sufficient employment land to meet the needs and requirements of a range of future employment scenarios (including increased automation and the significant contribution of SMEs to the Welsh economy) whilst ensuring that an over-supply of employment land does not prevent the release of land for other uses;
Welsh: sicrhau bod digon o dir cyflogaeth ar gael i ddiwallu anghenion a gofynion sefyllfaoedd cyflogaeth amrywiol yn y dyfodol (yn cynnwys mwy o annibyniaeth a chyfraniad sylweddol i BBaChau at economi Cymru) ond gan sicrhau nad yw gorgyflenwad o dir cyflogaeth yn rhwystro rhyddhau tir ar gyfer dibenion eraill;
English: promoting and diversifying our rural economy to ensure it is fit for the future and economically sustainable while ensuring that unnecessary development in the countryside is controlled;
Welsh: hyrwyddo ac arallgyfeirio'n heconomi wledig i sicrhau ei bod yn addas at y dyfodol ac yn economaidd gynaliadwy a sicrhau bod datblygu diangen mewn ardaloedd gwledig yn cael ei reoli.
English: capitalising on our distinctive tourism offer to promote Wales to the world, creating high quality jobs in this sector which enhance skills and provide employment year-round;
Welsh: manteisio ar ein cynnig nodedig i dwristiaid i hyrwyddo Cymru i'r byd, gan greu swyddi o ansawdd uchel yn y sector sy'n gwella sgiliau ac yn cynnig gwaith trwy'r flwyddyn;
English: readying Wales for further technological innovation in the mobile and broadband sector so it can adapt to future change while ensuring that all parts of Wales have access to modern communication systems;
Welsh: paratoi Cymru ar gyfer arloesedd technegol pellach yn y sector ffonau symudol a band eang fel y gall addasu i newid yn y newid gan sicrhau yr un pryd fod gan bob ardal yng Nghymru fynediad i systemau cyfathrebu modern;
