cy-gb	Ar gyfer unrhyw gynnig datblygu sy’n effeithio ar adeilad rhestredig neu ei leoliad, y brif ystyriaeth berthnasol yw’r gofyniad statudol i roi ystyriaeth arbennig i ddymunoldeb diogelu’r adeilad, ei leoliad neu unrhyw nodweddion o ddiddordeb pensaernïol neu hanesyddol arbennig sydd ganddo.

en-gb	6.1.11  For listed buildings, the aim should be to find the best way to protect and enhance their special qualities, retaining them in sustainable use.
cy-gb	6.1.11  Ar gyfer adeiladau rhestredig, y nod ddylai fod i ddod o hyd i’r ffordd orau o warchod a gwella eu rhinweddau arbennig, gan sicrhau y gellir parhau i wneud defnydd cynaliadwy ohonynt.

en-gb	The continuation or reinstatement of the original use should generally be the first option, but not all original uses will now be viable or appropriate.
cy-gb	Fel arfer, parhau â’r defnydd gwreiddiol neu ei adfer ddylai fod y dewis cyntaf ond ni fydd pob defnydd gwreiddiol yn ymarferol nac yn briodol mwyach.

en-gb	The application of planning and listed building controls should recognise the need for flexibility where new uses have to be considered in order to secure a building’s survival or provide it with a sound economic future.
cy-gb	Wrth weithredu rheolaethau cynllunio a rheolaethau adeilad rhestredig, dylid cydnabod yr angen am hyblygrwydd pan fydd yn rhaid ystyried ffyrdd newydd o ddefnyddio adeilad rhestredig er mwyn sicrhau y bydd adeilad yn goroesi neu y bydd ganddo ddyfodol economaidd cadarn.

en-gb	6.1.13  Applicants for listed building consent must be able to justify their proposals, show why the alteration or demolition of a listed building is desirable or necessary and consider the impact of any change upon its significance.
cy-gb	6.1.13  Mae’n rhaid i ymgeiswyr am ganiatâd adeilad rhestredig allu cyfiawnhau eu cynigion, dangos pam fod newid neu ddymchwel adeilad rhestredig yn ddymunol neu’n angenrheidiol ac ystyried effaith unrhyw newid ar ei arwyddocâd.

en-gb	This must be included in a heritage impact statement, which will be proportionate both to the significance of the building and to the degree of change proposed.

en-gb	6.1.16  Preservation or enhancement of a conservation area can be achieved by a development which either makes a positive contribution to an area’s character or appearance or leaves them unharmed.
cy-gb	6.1.16  Gall ardal gadwraeth gael ei diogelu neu ei gwella gan ddatblygiad sy’n gwneud cyfraniad cadarnhaol at gymeriad neu olwg ardal neu nad yw’n amharu arnynt.

cy-gb	Gellir ystyried mesurau lliniaru hefyd, a allai olygu bod datblygiad arfaethedig yn cael effaith niwtral neu gadarnhaol mewn ardal gadwraeth.

en-gb	6.1.17  Conservation area designation introduces control over the total or substantial demolition of unlisted buildings within these areas, but partial demolition does not require conservation area consent.
cy-gb	6.1.17  Mae dynodi ardaloedd cadwraeth yn golygu y gellir rheoli’r gwaith o ddymchwel adeiladau anrhestredig o fewn yr ardaloedd hyn yn gyfan gwbl neu’n sylweddol, ond nid oes angen caniatâd ardal gadwraeth er mwyn dymchwel adeiladau yn rhannol.

en-gb	Procedures are essentially the same as for listed building consent.
cy-gb	Mae’r gweithdrefnau fwy neu lai yr un peth â’r gweithdrefnau ar gyfer caniatâd adeilad rhestredig.

en-gb	When considering an application for conservation area consent, account should be taken of the wider effects of demolition on the building’s surroundings and on the architectural, archaeological or historic interest of the conservation area as a whole.
cy-gb	Wrth ystyried cais am ganiatâd ardal gadwraeth, dylid ystyried effeithiau ehangach y gwaith dymchwel ar yr ardal o amgylch yr adeilad ac ar ddiddordeb pensaernïol, archaeolegol neu hanesyddol yr ardal gadwraeth yn gyffredinol.

en-gb	Consideration should also be given to replacement structures.

en-gb	6.1.23  The planning system recognises the need to conserve archaeological remains.
cy-gb	6.1.23  Mae’r system gynllunio yn cydnabod yr angen i warchod olion archaeolegol.

en-gb	The conservation of archaeological remains and their settings is a material consideration in determining planning applications, whether those remains are a scheduled monument or not.
cy-gb	Mae gwarchod olion archaeolegol a’u lleoliad yn parhau i fod yn ystyriaeth berthnasol wrth benderfynu ar geisiadau cynllunio, p’un a yw’r olion hynny’n heneb gofrestredig ai peidio.

en-gb	6.1.24  Where nationally important archaeological remains are likely to be affected by proposed development, there should be a presumption in favour of their physical protection in situ.
cy-gb	6.1.24  Pan fydd datblygiad arfaethedig yn debygol o effeithio ar olion archaeolegol o bwys cenedlaethol, dylai fod rhagdybiaeth o blaid eu gwarchod yn ffisegol yn y fan a’r lle.

en-gb	It will only be in exceptional circumstances that planning permission will be granted if development would result in a direct adverse impact on a scheduled monument (or an archaeological site shown to be of national importance).

en-gb	6.1.25  In cases involving less significant archaeological remains, planning authorities will need to weigh the relative importance of the archaeological remains and their settings against other factors, including the need for the proposed development.
cy-gb	6.1.25  Mewn achosion sy’n cynnwys olion archaeolegol llai pwysig, bydd angen i awdurdodau cynllunio lleol bwyso a mesur pwysigrwydd cymharol yr olion archaeolegol a’u lleoliadau yn ôl ffactorau eraill, gan gynnwys yr angen am y datblygiad arfaethedig.

en-gb	6.1.26  Where archaeological remains are known to exist or there is a potential for them to survive, an application should be accompanied by sufficient information, through desk-based assessment and/or field evaluation, to allow a full understanding of the impact of the proposal on the significance of the remains.

cy-gb	Ni ddylai cynlluniau datblygu gynnwys polisïau sy’n ymwneud ag ariannu gwaith archaeolegol yn gyfnewid am roi caniatâd cynllunio.

en-gb	Planning permission for archaeologically damaging development should not be granted merely because it is proposed to record sites whose physical preservation in situ is both desirable (because of their level of importance) and feasible.
cy-gb	Ni ddylid rhoi caniatâd cynllunio ar gyfer datblygiad sy’n niweidiol yn archaeolegol dim ond oherwydd bod cynnig i gofnodi safleoedd y byddai’n ddymunol (oherwydd lefel eu pwysigrwydd) ac yn bosibl eu diogelu yn ffisegol yn y fan a’r lle.

cy-gb	6.2   Seilwaith Gwyrdd

en-gb	Green infrastructure is the network of natural and semi-natural features, green spaces, rivers and lakes that intersperse and connect places.
cy-gb	Seilwaith gwyrdd yw’r rhwydwaith o nodweddion naturiol a lled-naturiol, mannau gwyrdd, afonydd a llynnoedd sy’n britho ac yn cysylltu lleoedd.

en-gb	Component elements of green infrastructure can function at different scales.
cy-gb	Gall elfennau cydrannol seilwaith gwyrdd weithredu ar wahanol raddfeydd.

en-gb	At the landscape scale green infrastructure can comprise entire ecosystems such as wetlands, waterways and mountain ranges.
cy-gb	Ar lefel y dirwedd gall seilwaith gwyrdd gynnwys ecosystemau cyfan fel gwlyptiroedd, dyfrffyrdd a chadwyni mynyddoedd.

en-gb	At a local scale, it might comprise parks, fields, public rights of way, allotments, cemeteries and gardens.
cy-gb	Ar raddfa leol, gallai gynnwys parciau, caeau, hawliau tramwy cyhoeddus, rhandiroedd, mynwentydd a gerddi.

en-gb	At smaller scales, individual urban interventions such as street trees, hedgerows, roadside verges, and green roofs/walls can all contribute to green infrastructure networks.
cy-gb	Ar raddfeydd llai, gall ymyriadau trefol unigol fel coed stryd, perthi, ochr ffyrdd a thoeon/waliau gwyrdd i gyd gyfrannu at rwydweithiau seilwaith gwyrdd.

cy-gb	Gall seilwaith gwyrdd ddarparu sawl swyddogaeth ar yr un pryd ac felly o ganlyniad mae’n cynnig manteision lluosog, ar gyfer cydnerthedd cymdeithasol, economaidd yn ogystal ag amgylcheddol.

en-gb	The components of green infrastructure, by improving the resilience of ecosystems, can result in positive benefits to well-being including flood management, water purification, improved air quality, reduced noise pollution and local climate moderation, climate change mitigation and food production.
cy-gb	Gall elfennau seilwaith gwyrdd, drwy wella cydnerthedd ecosystemau, arwain at fanteision cadarnhaol i lesiant yn cynnwys rheoli llifogydd, puro dŵr, ansawdd aer gwell, llai o lygredd sŵn a chymedroli’r hinsawdd leol, lliniaru newid hinsawdd a chynhyrchu bwyd.

en-gb	These benefits are important in urban environments where they can facilitate health and well-being related benefits of open space, clean air and improved tranquility, for example, as well as creating a sense of place and improved social cohesion.
cy-gb	Mae’r manteision hyn yn bwysig mewn amgylcheddau trefol, lle gallant hwyluso’r manteision iechyd a llesiant sy’n gysylltiedig â mannau agored, aer glân a mwy o lonydd, er enghraifft, yn ogystal â chreu ymdeimlad o le a gwell cydlyniant cymdeithasol.

en-gb	In addition, green infrastructure has a role in protecting local distinctiveness, providing economic benefits and social and community opportunities.
cy-gb	Yn ogystal, mae gan seilwaith gwyrdd rôl mewn gwarchod natur unigryw ardal, darparu manteision economaidd a chyfleoedd cymdeithasol a chymunedol.

cy-gb	Trwy gynllunio a dylunio gofalus, gall seilwaith gwyrdd sicrhau bod manteision gwasanaethau bioamrywiaeth ac ecosystem yn cael eu rhoi ar waith mewn datblygiadau a lleoedd newydd, gan helpu i oresgyn y posibilrwydd o wrthdaro rhwng amcanion, a chyfrannu at amrywiaeth o ganlyniadau iechyd a llesiant.

en-gb	There are multiple ways of incorporating green infrastructure, dependent on the needs and opportunities a site presents.
cy-gb	Bydd sawl ffordd wahanol o ymgorffori seilwaith gwyrdd, yn dibynnu ar yr anghenion a’r cyfleoedd sy’n gysylltiedig â safle.

en-gb	Landscaping, green roofs, grass verges, sustainable urban drainage and gardens are examples of individual measures that can have wider cumulative benefits, particularly in relation to biodiversity and the resilience of ecosystems as well as in securing the other desired environmental qualities of places.
cy-gb	Mae tirlunio, toeon gwyrdd, ymylon gwyrdd, systemau draenio trefol cynaliadwy a gerddi yn enghreifftiau o fesurau unigol sy’n gallu esgor ar fanteision cynyddol ehangach, yn enwedig mewn perthynas â bioamrywiaeth a chydnerthedd ecosystemau yn ogystal â sicrhau rhinweddau amgylcheddol eraill a ddymunir mewn lleoedd.

en-gb	The Green Infrastructure Assessment should also be given early consideration in development proposals, and inform the implementation of projects.
cy-gb	Dylai’r Asesiad o Seilwaith Gwyrdd gael ei ystyried yn gynnar mewn cynigion datblygu hefyd, a llywio’r gwaith o weithredu cynigion prosiect.

en-gb	6.2.9  Considering how significant benefits can be delivered through green infrastructure will be a key aim of the assessment.
cy-gb	6.2.9  Un o brif amcanion yr asesiad yw ystyried sut y gall seilwaith gwyrdd esgor ar fanteision arwyddocaol.

en-gb	This may involve identifying opportunities to improve water management and flood mitigation through the provision of Sustainable Drainage Systems, including design measures such as green roofs.
cy-gb	Gallai hynny olygu nodi cyfleoedd i reoli dŵr a lleihau llifogydd yn well trwy ddarparu Systemau Draenio Cynaliadwy, gan gynnwys mesurau dylunio fel toeon gwyrdd.

en-gb	In a similar way, identifying how the provision of green infrastructure could form an integral part of strategies for growth will be an important factor in maintaining good air quality and appropriate soundscapes.
cy-gb	Mewn ffordd debyg, mae dangos sut y gall seilwaith gwyrdd fod yn rhan annatod o strategaethau twf fod yn ffactor bwysig wrth gynnal ansawdd aer da a seinweddau priodol.

en-gb	This should include identifying ways to minimise or reverse the fragmentation of habitats, and to improve habitat connectivity through the promotion of wildlife corridors and identifying opportunities for land rehabilitation, landscape management and the creation of new or improved habitats.
cy-gb	Dylai gynnwys nodi ffyrdd o leihau neu wyrdroi chwalu cynefinoedd, a gwella cysylltedd cynefinoedd drwy hyrwyddo coridorau bywyd gwyllt a nodi cyfleoedd i adfer tir, rheoli’r dirwedd a chreu cynefinoedd newydd neu well.

en-gb	Planning authorities should ensure that development minimises impact and provides opportunities for enhancement within areas identified as important for the ability of species to adapt and/or to move to more suitable habitats.
cy-gb	Dylai awdurdodau cynllunio gadw mor fach â phosib effeithiau datblygiad mewn ardal a nodwyd fel un bwysig i allu rhywogaethau i ymaddasu/a neu symud i gynefinoedd mwy addas a chynnig cyfleoedd i’w gwella.

en-gb	6.3.5  The statutory landscape designations that apply in Wales are National Parks, and AONBs.
cy-gb	6.3.5  Y dynodiadau tirwedd statudol sy’n  berthnasol yng Nghymru yw Parciau Cenedlaethol, ac AHNE.

en-gb	Planning authorities have a statutory duty to have regard to National Parks and AONB purposes.
cy-gb	Mae dyletswydd statudol ar awdurdodau cynllunio i ystyried dibenion Parciau Cenedlaethol ac AHNE.

en-gb	This duty applies in relation to all activities affecting National Parks and AONBs, whether those activities lie within, or in the setting of, the designated areas.
cy-gb	Mae’r ddyletswydd hon yn berthnasol i bob gweithgaredd sy’n effeithio ar Barciau Cenedlaethol ac AHNE, waeth a yw’r gweithgareddau hynny o fewn lleoliad yr ardaloedd dynodedig neu yng nghyffiniau’r ardaloedd hynny.

en-gb	The designated landscapes should be drivers of the sustainable use and management of natural resources in their areas, and planning authorities should have regard to their identified special qualities in the exercise of their functions and any relevant management plans.
cy-gb	Dylai’r tirweddau dynodedig fod yn sbardun i ddefnyddio a rheoli adnoddau naturiol mewn modd cynaliadwy yn eu hardaloedd, a dylai awdurdodau cynllunio ystyried eu rhinweddau arbennig penodol wrth arfer eu swyddogaethau ac unrhyw gynlluniau rheoli perthnasol.

en-gb	6.3.6  In National Parks, planning authorities should give great weight to the statutory purposes of National Parks, which are to conserve and enhance their natural beauty, wildlife and cultural heritage, and to promote opportunities for public understanding and enjoyment of their special qualities.
cy-gb	6.3.6  Dylai awdurdodau cynllunio parciau cenedlaethol roi pwys mawr ar ddibenion statudol Parciau Cenedlaethol, sef gwarchod a gwella eu harddwch naturiol, bywyd gwyllt a threftadaeth ddiwylliannol, a hyrwyddo cyfleoedd i’r cyhoedd ddeall a mwynhau eu priodoleddau.

en-gb	Planning authorities should also seek to foster the social, economic and cultural well-being of their local communities.
cy-gb	Dylai awdurdodau cynllunio fynd ati hefyd i feithrin llesiant cymdeithasol, economaidd a diwylliannol eu cymunedau lleol.

en-gb	The Sandford Principle provides that, where there is a conflict between these purposes, greater weight shall be given to conserving and enhancing natural beauty, wildlife and cultural heritage.

cy-gb	Ni ddylai datblygiadau mawr ddigwydd mewn Parciau Cenedlaethol neu Ardaloedd o Harddwch Naturiol Eithriadol ac eithrio o dan amgylchiadau eithriadol.

en-gb	This may arise where, after rigorous examination, there is demonstrated to be an overriding public need, refusal would be severely detrimental to the local economy and there is no potential for locating the development elsewhere or meeting the need in some other way.
cy-gb	Gallai hyn godi os gwelir, ar ôl archwiliad trwyadl, bod angen cyhoeddus sy’n drech na dim arall, y byddai gwrthod caniatâd yn niweidiol dros ben i’r economi leol a phan nad oes modd lleoli’r datblygiad mewn man arall neu ddiwallu’r angen mewn rhyw fodd arall.

en-gb	Any construction and restoration must be carried out to high environmental standards.
cy-gb	Rhaid cyflawni unrhyw waith adeiladu ac adfer yn ôl safonau amgylcheddol uchel.

cy-gb	Gallai hyn gynnwys polisïau ar gyfer nodweddion, priodoleddau a rhinweddau’r dirwedd sydd o bwys lleol, a dynodi Ardaloedd Tirwedd Arbennig (ATA).

en-gb	Planning authorities should state which features, characteristics or qualities require extra protection, and explain how the policy or designation will achieve this protection.
cy-gb	Dylai awdurdodau cynllunio ddatgan pa nodweddion, priodoleddau neu rinweddau sydd angen eu gwarchod ymhellach, ac egluro sut bydd y polisi neu’r dynodiad yn gwneud hynny.

en-gb	LANDMAP and any associated landscape character assessments (including the register of historic landscapes in Wales) should be used to inform local landscape policies and SPG, and to help identify or revise SLAs.
cy-gb	Dylid defnyddio LANDMAP ac unrhyw asesiadau cysylltiedig o gymeriad tirwedd (gan gynnwys y gofrestr o dirweddau hanesyddol yng Nghymru) wrth baratoi polisïau tirwedd lleol a chanllawiau cynllunio atodol, ac i helpu i nodi neu ddiwygio ATA.

en-gb	6.3.12  SLAs are non-statutory designations that define local areas of high landscape importance, which may be unique, exceptional or distinctive to the area.
cy-gb	6.3.12  Dynodiadau anstatudol yw ATA sy’n diffinio ardaloedd lleol o bwysigrwydd tirwedd mawr, a allai fod yn unigryw, yn eithriadol neu’n benodol i’r ardal.

en-gb	Planning authorities should apply these designations where there is good reason to believe that normal planning policies cannot provide the necessary protection.
cy-gb	Dylai awdurdodau cynllunio roi’r dynodiadau hyn ar waith lle mae rheswm da dros gredu na all polisïau cynllunio arferol eu gwarchod yn ddigonol.

en-gb	6.3.13  Geological features are a key part of our natural environment, and protecting geodiversity underpins the wider protection and management of our natural resources, including land availability, renewable energy potential, groundwater supply and flood risk.
cy-gb	6.3.13  Mae nodweddion daearegol yn rhan allweddol o’n hamgylchedd naturiol, ac mae gwarchod geoamrywiaeth yn sail i’r gwaith ehangach o warchod a rheoli ein hadnoddau naturiol, yn cynnwys argaeledd tir, potensial o ran ynni adnewyddadwy, cyflenwad dŵr daear a pherygl llifogydd.

en-gb	RIGS are selected for their educational, scientific, historic and aesthetic qualities, to and designated through development plans.
cy-gb	Caiff RIGS eu dewis am eu rhinweddau addysgol, gwyddonol, hanesyddol ac esthetig, a chânt eu dynoi trwy gynlluniau datblygu.

en-gb	6.3.15  Planning authorities should protect the features and qualities for which Geoparks and RIGS have been designated, and are encouraged to promote opportunities for the incorporation of geological features within the design of development, particularly where relevant evidence is provided by Green Infrastructure Assessments.
cy-gb	6.3.15  Dylai awdurdodau cynllunio warchod y nodweddion a’r rhinweddau y mae Geoparciau a RIGS wedi’u dynodi o’u herwydd, ac fe’u hanogir i hyrwyddo cyfleoedd ar gyfer ymgorffori nodweddion daearegol wrth ddylunio datblygiad, yn enwedig lle mae tystiolaeth berthnasol yn dod i’r amlwg trwy Asesiadau o’r Seilwaith Gwyrdd.

en-gb	6.3.16  Some statutory Sites of Special Scientific Interest (SSSIs) are also designated for their nationally important geological or geomorphological features, and planning authorities have a duty to further the conservation and enhancement of those features.
cy-gb	6.3.16  Caiff rhai Safleoedd o Ddiddordeb Gwyddonol Arbennig (SoDdGA) eu dynodi hefyd am eu nodweddion daearegol neu geomorffolegol sydd o bwys cenedlaethol, ac mae dyletswydd ar awdurdodau cynllunio i wneud mwy i warchod a gwella’r nodweddion hynny.

en-gb	6.4.1  Biodiversity underpins the structure and functioning of ecosystems.
cy-gb	6.4.1  Mae bioamrywiaeth yn sail i strwythur a gweithrediad ecosystemau.

en-gb	It is the diversity of living organisms whether at the genetic, species or ecosystem level.
cy-gb	Mae’n golygu amrywiaeth organebau byw boed hynny ar lefel genetig, rhywogaeth neu ecosystem.

en-gb	An ecosystem is made up of living organisms, plants, animals and micro-organisms, in conjunction with their non-living environment, air, water, minerals and soil, and all the diverse and complex interactions that take place between them.
cy-gb	Mae ecosystem yn cynnwys organebau byw, planhigion, anifeiliaid a micro-organebau, ar y cyd â’u hamgylchedd anfyw (aer, dŵr, mwynau a phridd) a’r holl ryngweithio amrywiol a chymhleth sy’n digwydd rhyngddynt.

en-gb	6.4.2  The Environment (Wales) Act 2016  introduced an enhanced biodiversity  and resilience of ecosystems duty (Section 6 Duty).
cy-gb	6.4.2  Cyflwynodd Deddf yr Amgylchedd  (Cymru) 2016 ddyletswydd uwch  yn ymwneud â bioamrywiaeth a chydnerthedd ecosystemau (dyletswydd adran 6).

en-gb	This duty applies to public authorities in the exercise of their functions in relation to Wales and will help maximise contributions to achieving the well-being goals.
cy-gb	Mae’r ddyletswydd hon yn berthnasol i awdurdodau cyhoeddus wrth arfer eu swyddogaethau mewn perthynas â Chymru a bydd yn helpu i sicrhau’r cyfraniadau mwyaf posibl at gyflawni nodau llesiant.

en-gb	The Nature Recovery Action Plan supports this legislative requirement to reverse the decline in biodiversity, address the underlying causes of biodiversity loss by putting nature at the heart of decision-making and increasing the resilience of ecosystems by taking specific action focused around the 6 objectives for habitats and species.

en-gb	Biodiversity is defined by the CBD as “the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part;
cy-gb	Diffinnir bioamrywiaeth gan y Confensiwn ar Amrywiaeth Fiolegol (CBD) fel yr amrywiaeth ymysg organebau byw o bob ffynhonnell yn cynnwys, ymhlith eraill, y tir, y môr ac ecosystemau dyfrol eraill a’r cymhlethdodau ecolegol maent yn rhan ohonynt;

en-gb	this includes diversity within species, between species and of ecosystems”.
cy-gb	mae hyn yn cynnwys amrywiaeth o fewn rhywogaethau, rhwng rhywogaethau ac mewn ecosystemau.

en-gb	Diversity is a structural feature of ecosystems, and the variability among ecosystems is an element of biodiversity.
cy-gb	Mae amrywiaeth yn nodwedd strwythurol o ecosystemau, ac mae amrywiaeth ymhlith ecosystemau yn elfen o fioamrywiaeth.

en-gb	Ecosystems.The CBD defined ecosystems as “a dynamic complex of plant, animal and micro-organisms and their non-living environment interacting as a functional unit”.
cy-gb	Ecosystemau Roedd CBD yn diffinio ecosystemau fel cymhlethfa ddeinamig o blanhigion, anifeiliaid a micro-organebau a’u hamgylchedd anfyw yn rhyngweithio fel uned weithredol.

en-gb	The key feature of ecosystems is that they are fully integrated systems with ‘emergent properties’ arising from interactions between the living and non-living elements of which they are composed.
cy-gb	Nodwedd allweddol ecosystemau yw eu bod yn systemau sydd wedi’u hintegreiddio’n llawn gyda nodweddion newydd sy’n deillio o ryngweithio rhwng yr elfennau byw ac anfyw sy’n eu creu.

en-gb	6.4.3  The planning system has a key role to  play in helping to reverse the decline in biodiversity and increasing the resilience of ecosystems, at various scales, by ensuring appropriate mechanisms are in place to both protect against loss and to secure enhancement.
cy-gb	6.4.3  Mae gan y system gynllunio rôl allweddol   o ran helpu i wrthdroi’r dirywiad mewn bioamrywiaeth a chynyddu cydnerthedd ecosystemau, ar wahanol raddfeydd, drwy sicrhau bod mecanweithiau priodol ar waith i ddiogelu rhag colled a sicrhau gwelliant.

en-gb	Addressing the consequences of climate change should be a central part of any measures to conserve biodiversity and the resilience of ecosystems.
cy-gb	Dylai mynd i’r afael â chanlyniadau newid yn yr hinsawdd fod yn rhan ganolog o unrhyw fesurau i warchod bioamrywiaeth a chydnerthedd ecosystemau.

en-gb	Information contained in SoNaRR, Area Statements and species records from Local Environmental Record Centres should be taken into account.
cy-gb	Dylid ystyried gwybodaeth yn yr Adroddiad ar Sefyllfa Adnoddau Naturiol, Datganiadau Ardal ac adroddiadau ar rywogaethau gan Ganolfannau Cofnodion Amgylcheddol.

en-gb	Development plan strategies, policies and development proposals must consider the need to:
cy-gb	Mae angen i strategaethau, polisïau a chynigion datblygu cynlluniau datblygu ystyried yr angen i:

en-gb	support the conservation of biodiversity, in particular the conservation of wildlife and habitats;
cy-gb	gefnogi cadwraeth bioamrywiaeth, yn enwedig cadwraeth bywyd gwyllt a chynefinoedd;

en-gb	ensure action in Wales contributes to meeting international responsibilities and obligations for biodiversity and habitats;

en-gb	6.4.4  It is important that biodiversity and resilience considerations are taken into account at an early stage in both development plan preparation and when proposing or considering development proposals.
cy-gb	6.4.4  Mae’n bwysig bod ystyriaethau bioamrywiaeth a chydnerthedd yn cael eu hystyried yn gynnar wrth baratoi cynlluniau datblygu ac wrth gynnig neu ystyried cynigion datblygu.

en-gb	Since these considerations are not confined by administrative boundaries they must be addressed strategically through consultation and collaboration with adjoining planning authorities and other bodies such as NRW and the third sector.
cy-gb	Gan nad yw ystyriaethau hyn yn cael eu cyfyngu gan ffiniau gweinyddol, mae’n rhaid mynd i’r afael â nhw’n strategol drwy ymgynghori a chydweithio gydag awdurdodau cynllunio cyfagos a chyrff eraill fel CNC a’r trydydd sector.

en-gb	All reasonable steps must be taken to maintain and enhance biodiversity and promote the resilience of ecosystems and these should be balanced with the wider economic and social needs of business and local communities.

cy-gb	6.4.5  Rhaid i awdurdodau cynllunio geisio cynnal a gwella bioamrywiaeth wrth arfer eu swyddogaethau.

en-gb	This means development should not cause any significant loss of habitats or populations of species, locally or nationally and must provide a net benefit for biodiversity.

en-gb	Implementing the Section 6 Duty
cy-gb	Gweithredu Dyletswydd Adran 6

en-gb	Diversity: to ensure mechanisms are in place to minimise further loss and where circumstances allow for species’ populations to expand and recolonise their natural range (former range) or adapt to future change.
cy-gb	Amrywiaeth: sicrhau bod mecanweithiau ar waith i leihau rhagor o golledion a lle bo amgylchiadau’n caniatáu, galluogi poblogaethau rhywogaethau i ehangu ac ail-gytrefu eu cynefin naturiol (cyn gynefin) neu ymaddasu i newidiadau’r dyfodol.

en-gb	More diverse ecosystems are more resilient to external influences (this includes biological, geological and physical diversity on a site).
cy-gb	Mae ecosystemau mwy amrywiol yn gallu gwrthsefyll dylanwadau allanol yn well (mae hyn yn cynnwys amrywiaeth fiolegol, daearegol a ffisegol y safle).

en-gb	This means development should not cause any significant loss of habitats or populations of species, locally or nationally and must provide a net benefit for biodiversity;
cy-gb	Mae hyn yn golygu na ddylai datblygu arwain at golledion mawr i gynefinoedd na phoblogaethau rhywogaethau, yn lleol nac yn genedlaethol a rhaid iddo esgor ar fanteision net i fioamrywiaeth;

en-gb	Extent: to ensure mechanisms allow for the identification of potential habitat, the maintenance of existing assets and networks and promote the restoration of damaged, modified or potential habitat and the creation of new habitat.
cy-gb	Hyd a lled: sicrhau bod mecanweithiau’n caniatáu ar gyfer clustnodi cynefin posib. cynnal asedau a rhwydweithiau sy’n bodoli eisoes a hyrwyddo’r gwaith o adfer cynefinoedd sydd wedi’u difrodi neu eu haddasu neu ddarpar gynefinoedd a chreu cynefinoedd newydd.

en-gb	This means that planning decisions should incorporate measures which seek the creation, restoration and appropriate management of green networks and linkages between habitats and maintaining and enhancing other green infrastructure features and networks;
cy-gb	Mae hyn yn golygu y dylai penderfyniadau cynllunio gynnwys mesurau sy’n ceisio creu, adfer a rheoli’n briodol rwydweithiau gwyrdd a chysylltiadau rhwng cynefinoedd a chynnal a gwella nodweddion a rhwydweithiau seilwaith gwyrdd eraill;

en-gb	Condition: Ecosystems need to be in a healthy condition to function effectively, to deliver a range of important ecosystem services.
cy-gb	Cyflwr: mae angen i ecosystemau fod mewn cyflwr iach i weithio’n effeithiol ac i ddarparu’r ystod o wasanaethau pwysig ecosystemau.

en-gb	Planning decisions should not compromise the condition of ecosystems.
cy-gb	Ni ddylai penderfyniadau cynllunio beryglu cyflwr ecosystemau.

en-gb	By taking an integrated approach to development, for example, which considers both direct and wider impacts and benefits it should be possible to make a positive contribution.
cy-gb	Trwy ddatblygu mewn dull integredig, er enghraifft, sy’n ystyried effeithiau a manteision uniongyrchol a rhai ehangach, dylai fod modd gwneud cyfraniad cadarnhaol.

en-gb	Planning for the long term management of retained habitats is key to maintaining condition through for example, the use of planning obligations;
cy-gb	Mae cynllunio yn y tymor hir ar gyfer rheoli cynefinoedd a gedwir yn allweddol i ddiogelu’u cyflwr trwy er enghraifft, defnyddio rhwymedigaethau cynllunio;

en-gb	Connectivity: to take opportunities to develop functional habitat and ecological networks within and between ecosystems and across landscapes, building on existing connectivity and quality and encouraging habitat creation, restoration and appropriate management.
cy-gb	Cysylltedd: manteisio ar gyfleoedd i ddatblygu cynefin a rhwydweithiau ecolegol gweithredol o fewn a rhwng ecosystemau ac ar draws tirweddau, gan adeiladu ar gysylltedd ac ansawdd sy’n bodoli eisoes ac annog creu, adfer a rheoli cynefinoedd yn briodol.

en-gb	The opportunities could include enlarging habitat areas, developing buffers around designated sites or other biodiversity assets or corridors, including transport and river corridors, and the creation of ‘stepping stones’ which will strengthen the ability of habitats and ecological networks to adapt to change, including climate change;
cy-gb	Gallai’r cyfleoedd gynnwys ehangu ardaloedd cynefinoedd, datblygu clustogfeydd o amgylch safleoedd dynodedig neu asedau neu goridorau bioamrywiaeth eraill, gan gynnwys coridorau afonydd a thrafnidiaeth, a chreu ‘cerrig sarn’ a fydd yn cryfhau gallu cynefinoedd a rhwydweithiau ecolegol i addasu i newid, yn cynnwys newid yn yr hinsawdd;

en-gb	Adaptability to change: primarily in the form of climate change, for both species (diversity) and ecosystems requires action to protect the extent, condition and connectivity of habitats, features and ecological networks.
cy-gb	Mae’r gallu i addasu i newid, yn bennaf ar ffurf newid hinsawdd, ar gyfer rhywogaethau (amrywiaeth) ac ecosystemau yn gofyn am gamau i warchod hyd a lled, cyflwr a chysylltedd cynefinoedd, nodweddion a rhwydweithiau ecolegol.

en-gb	Development plans, planning proposals and applications which build on protecting designated sites and securing and enhancing green infrastructure will be key ways of addressing the attributes of ecosystems resilience identified in the Environment Act as well as facilitating social and economic resilience aspirations of the Well-being of Future Generations Act.
cy-gb	Bydd cynlluniau datblygu, cynigion cynllunio a cheisiadau sy’n adeiladu ar warchod safleoedd dynodedig a sicrhau a gwella seilwaith gwyrdd yn ffyrdd allweddol o fynd i’r afael â nodweddion cydnerthedd ecosystemau a nodir yn Neddf yr Amgylchedd yn ogystal â hwyluso dyheadau cydnerthedd cymdeithasol ac economaidd Deddf Llesiant Cenedlaethau’r Dyfodol.

en-gb	6.4.17  SSSIs are of national importance.
cy-gb	6.4.17  Mae SoDdGA o bwys cenedlaethol.

en-gb	The Wildlife and Countryside Act 1981, as amended by the Countryside and Rights of Way Act 2000, places a duty on all public bodies, including planning authorities, to take reasonable steps, consistent with the proper exercise of their functions, to further the conservation and enhancement of the features by reason of which a SSSI is of special interest.
cy-gb	Mae Deddf Bywyd Gwyllt a Chefn Gwlad 1981, fel y’i diwygiwyd gan Ddeddf Cefn Gwlad Hawliau Tramwy 2000, yn rhoi dyletswydd ar bob corff cyhoeddus, gan gynnwys awdurdodau cynllunio, i gymryd camau rhesymol, sy’n gyson â’r ffordd gywir o arfer eu swyddogaethau, i barhau i warchod a gwella’r nodweddion sy’n pennu bod SoDdGA o ddiddordeb arbennig.

en-gb	SSSIs can be damaged by developments within or adjacent to their boundaries, and in some cases, by development some distance away.
cy-gb	Gall SoDdGA gael ei ddifrodi gan ddatblygiadau y tu mewn i’w ffiniau neu gerllaw ac, mewn rhai achosion, gan ddatblygiadau sydd gryn bellter i ffwrdd.

en-gb	There is a presumption against development likely to damage a SSSI and this presumption should be appropriately reflected in development plans and development management decisions.
cy-gb	Ceir rhagdybiaeth yn erbyn datblygiad sy’n debygol o beri niwed i SoDdGA a dylid adlewyrchu’r rhagdybiaeth hon mewn ffordd briodol mewn cynlluniau datblygu a phenderfyniadau rheoli datblygu.

en-gb	In particular, before authorising development likely to damage any of the notified features of a SSSI, planning authorities must give notice of the proposed operations to NRW, and must take its advice into account in deciding whether to grant planning permission and in attaching planning conditions.
cy-gb	Yn arbennig, cyn awdurdodi gweithrediadau sy’n debygol o niweidio unrhyw un o nodweddion hysbys SoDdGA, rhaid i awdurdodau cynllunio lleol rybuddio CNC am y gweithrediadau arfaethedig, a rhaid iddynt ystyried ei gyngor wrth benderfynu a ddylid rhoi caniatâd cynllunio ai peidio ac wrth osod amodau cynllunio.

en-gb	For the purposes of land use planning proposed SSSIs will be treated in the same way as notified SSSIs .

en-gb	6.4.18  SACs and SPAs are of European importance.
cy-gb	6.4.18  Mae safleoedd ACA ac AGA o bwys Ewropeaidd.

en-gb	Under the Conservation of Habitats and Species Regulations (2017) (the Habitats Regulations), all public bodies (including planning authorities) must have regard to the requirements of the EC Habitats and Birds Directives when carrying out their functions.
cy-gb	O dan Reoliadau Gwarchod Cynefinoedd a Rhywogaethau (2017) (y Rheoliadau Cynefinoedd), rhaid i bob corff cyhoeddus (gan gynnwys awdurdodau cynllunio) ystyried gofynion Cyfarwyddebau Cynefinoedd ac Adar yr CE wrth arfer ei swyddogaethau.

en-gb	SACs and SPAs on land are underpinned by notification as SSSIs and hence subject to protection afforded by the SSSI provisions.
cy-gb	Atgyfnerthir ACAoedd ac AGAoedd trwy eu dynodi’n SoDdGAoedd sy’n eu gwarchod fel baent yn SoDdGA.

en-gb	Before authorising development or adopting a land use plan which is likely to have a significant effect on a SAC or SPA (including where outside the boundary of the SAC or SPA), planning authorities must carry out an appropriate assessment of the implications for the designated features, consult NRW and have regard to NRW’s representations.
cy-gb	Cyn caniatáu datblygiad neu cyn mabwysiadu cynllun defnyddio tir sy’n debygol o gael effaith arwyddocaol ar ACA neu AGA (gan gynnwys tir y tu allan i ffin ACA neu AGA), rhaid i awdurdodau cynllunio gynnal asesiad priodol o’r goblygiadau i’r nodweddion dynodedig, ymgynghori â CNC a rhoi sylw i farn CNC.

en-gb	The development can normally only be authorised or the plan adopted, if the planning authority ascertains that it will not adversely affect the integrity of the site, if necessary taking into account any additional measures, planning conditions or obligations.
cy-gb	Fel arfer, ni chaiff y datblygiad ei ganiatáu neu’r cynllun ei fabwysiadu ond os gwêl yr awdurdod cynllunio na chaiff effaith andwyol ar integriti’r safle, gan ystyried hefyd yn ôl y gofyn unrhyw fesurau, amodau cynllunio neu rwymedigaethau ychwanegol.

en-gb	Development or policies in land use plans for which there is no alternative solution and which must be carried out for imperative reasons of over-riding public interest may be authorised notwithstanding a negative assessment of the implications, subject to notifying Welsh Ministers.
cy-gb	Gellir caniatáu datblygiad neu bolisi mewn cynllun defnyddio tir os na ellir cyflawni ei ganlyniadau fel arall a bod yn rhaid ei gynnal am ei fod yn angenrheidiol er gwir les y cyhoedd serch asesiad negyddol o’r goblygiadau, cyn belled ag yr hysbysir Gweinidogion Cymru amdano.

en-gb	Any necessary compensatory measures to protect the overall coherence of the network of SACs and SPAs must be secured.
cy-gb	Rhaid cymryd unrhyw fesurau sydd eu hangen i ddiogelu cydlyniant cyffredinol y rhwydwaith o ACA ac AGA.

en-gb	Ramsar sites are important wetland areas designated under the Ramsar Convention on Wetlands of International importance.
cy-gb	Mae safleoedd Ramsar yn ardaloedd pwysig o wlyptir a ddynodir o dan Gonfensiwn Ramsar ar Wlyptiroedd o bwys rhyngwladol.

en-gb	As with SACs and SPAs, Ramsar sites are underpinned by notification as SSSIs, but are not subject to the Habitats Regulations.
cy-gb	Fel ag yn achos ACA ac AGA, atgyfnerthir safleoedd Ramsar trwy eu dynodi’n SoDdGa ond ni ddônt o dan y Rheoliadau Cynefinoedd.

en-gb	However, Ramsar sites should be treated within the planning system in the same way as SACs and SPAs.
cy-gb	Er hynny, dylid trin safleoedd Ramsar o fewn y system gynllunio fel pe baent yn ACAoedd neu AGAoedd.

en-gb	Proposed Special Areas of  Conservation, Special Protection  Areas and Ramsar sites
cy-gb	Ardaloedd Gwarchodaeth Arbennig, Ardaloedd Cadwraeth Arbennig a Safleoedd Ramsar a gynigir

en-gb	6.4.19  Sites which have been formally proposed as SPAs, SACs but which are not yet subject to legal protection under the Habitats Regulations, should be treated within the planning system in the same way as if they were legally designated.
cy-gb	6.4.19  Dylai safleoedd sydd wedi’u cynnig yn ffurfiol fel ACA neu AGA ac nad ydynt yn dod o dan amddiffyniad cyfreithiol y Rheoliadau Cynefinoedd eto, gael eu trin gan y system gynllunio fel pe baent wedi’u dynodi’n ACA neu AGA.

en-gb	The same considerations should, as a matter of policy, be applied to proposed Ramsar sites.

en-gb	Protection for Non-statutory Designations
cy-gb	Gwarchod Dynodiadau Anstatudol

en-gb	6.4.20 Although non-statutory designations carry less weight than statutory designations, they can make a vital contribution to delivering an ecological network for biodiversity and resilient ecosystems, and they should be given adequate protection in development plans and the development management process.
cy-gb	6.4.20 Er nad yw dynodiadau anstatudol mor ddylanwadol â dynodiadau statudol, maent yn gallu gwneud cyfraniad hanfodol at sicrhau rhwydwaith ecolegol ar gyfer bioamrywiaeth ac ecosystemau cydnerth a dylai cynlluniau datblygu a’r broses rheoli datblygu roi amddiffyniad digonol iddynt.

en-gb	Before authorising development likely to damage a local wildlife designation, planning authorities should give notice of the proposed operation to the County Ecologist and third sector environmental organisations.
cy-gb	Cyn awdurdodi datblygiad sy’n debygol o ddifrodi dynodiad natur lleol, dylai awdurdodau cynllunio roi hybysiad o’r bwriad i gynnal y gwaith i Ecolegydd y Sir neu i fudiad amgylcheddol y trydydd sector.

en-gb	Where a Green Infrastructure Assessment has identified that certain features or characteristics of the site need to be conserved or enhanced, planning authorities should state in their development plans what features or characteristics require this extra protection and why, and explain how the policies will achieve this protection.
cy-gb	Pan fydd Asesiad o’r Seilwaith Gwyrdd wedi nodi bod angen gwarchod neu wella nodweddion neu briodoleddau penodol y safle, dylai awdurdodau cynllunio ddatgan yn eu cynlluniau datblygu pa nodweddion neu briodoleddau sydd angen yr amddiffyniad ychwanegol hwn a pham, ac egluro sut bydd y polisïau’n sicrhau’r amddiffyniad hwn.

en-gb	Assessments should similarly consider the presence of protected and priority species including those on the Section 7 list and appropriate weight attached to their protection.
cy-gb	Yn yr un modd, dylai asesiadau ystyried presenoldeb rhywogaethau a warchodir a rhywogaethau â blaenoriaeth yn cynnwys y rhai ar y rhestr Adran 7 a dylid rhoi pwyslais digonol ar eu diogelu.

en-gb	Policies for non-statutory sites should make it clear that such designations do not preclude appropriate developments, where there are no adverse impacts on the features for which a site is designated.
cy-gb	Dylai polisïau ar gyfer safleoedd anstatudol ei gwneud hi’n glir nad yw dynodiadau o’r fath yn atal gweithgareddau economaiddgymdeithasol priodol lle na cheir effeithiau andwyol ar y nodweddion y cafodd y safle ei ddynodi i’w gwarchod.

cy-gb	rhaid darparu gwelliannau lle medrir.

en-gb	The first priority for planning authorities is to avoid damage to biodiversity and ecosystem functioning.
cy-gb	Y flaenoriaeth gyntaf i awdurdodau cynllunio yw osgoi difrod i fioamrywiaeth a gallu’r ecosystem i weithio.

en-gb	Where there may be harmful environmental effects, planning authorities will need to be satisfied that any reasonable alternative sites that would result  in less harm, no harm or gain have been fully considered

en-gb	The provision of up to date ecological survey information will assist in this process.
cy-gb	Byddai darparu gwybodaeth gyfoes o arolygon ecolegol yn helpu’r broses.

en-gb	An ecological survey to confirm whether a protected species is present and an assessment of the likely impact of the development on a protected species may be required in order to inform the development management process.
cy-gb	Er mwyn cael gwybodaeth i helpu i lywio’r penderfyniad cynllunio, efallai y bydd angen arolwg ecolegol i gadarnhau a oes rhywogaeth a warchodir yn bresennol ac asesiad o effaith debygol y datblygiad ar rywogaeth a warchodir er mwyn helpu’r broses rheoli datblygu.

en-gb	It is considered best practice that screening to determine the presence of protected species should by carried out by a competent ecologist on the basis of data provided by the relevant Local Environmental Record Centre.

en-gb	The particular landscapes of the coastline should be recognised and protected where they represent significant characteristics of place.
cy-gb	Dylai tirweddau penodol yr arfordir gael eu cydnabod a’u gwarchod os ydynt yn cynrychioli priodoleddau arwyddocaol lle.

en-gb	Designation as a heritage coast does not directly affect the status of the area in planning terms, however, the features which contributed to the designation of such areas will be important considerations in development plans and in making development management decisions.

en-gb	Coastal Change
cy-gb	Newid i’r Arfordir

en-gb	6.5.14  As part of understanding the characteristics of coastlines it should be recognised that sea level rise, storm surge, wave action and changes in coastal morphology and sediment supply can lead to both direct and indirect effects at the coast.
cy-gb	6.5.14  Fel rhan o’r gwaith o ddeall priodoledd arfordiroedd, dylid cydnabod bod lefel y môr yn codi, ymchwydd storm, gweithrediad tonnau a newidiadau mewn morffoleg arfordirol a chyflenwad gwaddodion yn gallu arwain at effeithiau uniongyrchol ac anuniongyrchol ar yr arfordir.

en-gb	Uncertainty is further exacerbated by the effects of climate change.
cy-gb	Gellir gwaethygu ansicrwydd ymhellach gan effeithiau newid hinsawdd.

en-gb	6.5.15  Whilst coastal morphology can be a protective feature against sea level rise, storm surge and wave action, the construction of coastal defences can potentially influence sediment supply by transferring the risks of erosion elsewhere.
cy-gb	6.5.15  Er y gall morffoleg yr arfordir fod yn nodwedd warchodol rhag lefel y môr yn codi, ymchwydd storm a gweithrediad tonnau, gall adeiladu amddiffynfeydd arfordirol ddylanwadu ar y cyflenwad gwaddodion drwy drosglwyddo’r risg o erydu i rywle arall.

en-gb	This possibility, given that erosion and the risk of inundation are likely to be exacerbated by climate change, should be avoided.
cy-gb	Dylid osgoi’r posibilrwydd hwn, o gofio bod erydu a’r risg o lifogydd yn debygol o waethygu oherwydd newid hinsawdd.

en-gb	It is not appropriate for development in one location to unacceptably add to the impacts of physical change to the coast in another location.
cy-gb	Nid yw’n briodol bod datblygiad mewn un lleoliad yn ychwanegu’n annerbyniol at effeithiau newid ffisegol i’r arfordir mewn lleoliad arall.

en-gb	6.5.16  Shoreline Management Plans are developed by local authorities in partnership with a range of stakeholders and establish long-term local policy frameworks for the management of coastal risk.
cy-gb	6.5.16  Mae Cynlluniau Rheoli Traethlin yn cael eu datblygu gan awdurdodau lleol mewn partneriaeth ag amrywiaeth o randdeiliaid ac maent yn pennu fframweithiau polisi lleol hirdymor ar gyfer rheoli risg arfordirol.

en-gb	The priorities contained within them should influence and inform the preparation of development plans.
cy-gb	Dylai’r blaenoriaethau ynddynt ddylanwadu ar y gwaith o baratoi cynlluniau datblygu a’u llywio.

en-gb	Where it is established that coastal defences will no longer be maintained, development plans should include clear and specific policies to manage development in such areas, including where they feel development would be unsuitable or where specific characteristics should be considered.
cy-gb	Pan bennir na fydd amddiffynfeydd arfordirol yn cael eu cynnal mwyach, dylai cynlluniau datblygu gynnwys polisïau clir a phenodol i reoli datblygiad mewn ardaloedd o’r fath, yn cynnwys ble maent yn teimlo y byddai datblygiad yn anaddas neu y dylid ystyried nodweddion penodol.

en-gb	6.5.17  Shoreline Management Plans will influence whether development itself can be justified or how it should be designed.
cy-gb	6.5.17  Bydd Cynlluniau Rheoli Traethlin yn dylanwadu ar a ellir cyfiawnhau’r datblygiad ei hun neu sut dylai gael ei ddylunio.

en-gb	Some areas of coastline will be covered by active policies of intervention in Shoreline Management Plans to defend the line and clear timescales will be in place governing these policies.
cy-gb	Bydd rhai darnau o’r arfordir yn destun polisïau ymyrryd gweithredol mewn Cynlluniau Rheoli Traethlin i amddiffyn y llinell a bydd amserlenni clir ar waith yn llywodraethu’r polisïau hyn.

en-gb	Other areas, which may already be developed, will not have active interventions associated with defence or may have managed setback, or realignment, identified as the appropriate response to inundation.
cy-gb	Ni fydd gan ardaloedd eraill, sydd eisoes wedi cael eu datblygu o bosibl, ymyriadau gweithredol sy’n gysylltiedig ag amddiffyn na chynlluniau ildio, neu ail-alinio, fel yr ymateb mwyaf priodol i lifogydd.

en-gb	Managed realignment may also be the favoured option in areas of low public exposure to risk or where land values make it difficult to justify public expenditure on engineering works, such as the case in low lying undeveloped coastal areas.
cy-gb	Mae’n bosibl mai  ail-alinio rheoledig fydd yr opsiwn a ffefrir mewn ardaloedd lle mae cysylltiad y cyhoedd â’r risg yn isel neu le mae gwerth y tir yn ei gwneud hi’n anodd cyfiawnhau gwariant cyhoeddus ar waith peirianyddol, fel sy’n wir mewn ardaloedd arfordirol heb eu datblygu sydd ar dir isel.

en-gb	Bearing these considerations in mind, proposed development in areas of coastal change should only take place where risks and consequences are understood and can be acceptably managed over the lifetime of the development.
cy-gb	O gofio’r ystyriaethau hynny, ni ddylid caniatâu datblygiad mewn ardaloedd lle mae’r arfordir yn newid oni deellir y risgiau a’r canlyniadau ac y gellir eu rheoli’n dderbyniol dros oes y datblygiad.

en-gb	6.5.19  Development should not generally be proposed or permitted in areas which would need expensive engineering works, either to protect developments on land subject to erosion by the sea or to defend land which might be inundated by the sea.
cy-gb	6.5.19  Ni ddylai datblygiad gael ei gynnig neu ei ganiatáu mewn ardaloedd a fyddai’n gofyn am waith peirianyddol drud, naill ai i amddiffyn datblygiadau ar y tir a allai gael eu herydu gan y môr neu i amddiffyn tir y gallai’r môr orlifo arno.

en-gb	Where active interventions are needed in areas which already contain development, a full understanding of the implications will need to be drawn up by the local authority in conjunction with all relevant stakeholders and roles and responsibilities in the process clearly identified.
cy-gb	Lle bo angen ymyriadau gweithredol mewn ardaloedd sydd â datblygiad ynddynt eisoes, bydd angen i’r awdurdod lleol, ar y cyd â’r holl randdeiliaid perthnasol, ddangos bod yna ddealltwriaeth lawn o’r goblygiadau a rhaid nodi rolau a chyfrifoldebau pawb yn y broses.

en-gb	6.5.20  In considering new coastal defence works, account should be taken of all potential environmental effects, both on and off-shore, including the impacts on habitat fragmentation and consequential ‘coastal squeeze’, as well as information contained in Shoreline Management Plans and other relevant documents such as Area Statements.

en-gb	The water industry itself is a source of green jobs and water services support energy and food production, recreation and tourism and connect homes and businesses to the infrastructure networks upon which they depend.
cy-gb	Mae’r diwydiant dŵr ei hun yn ffynhonnell swyddi gwyrdd ac mae gwasanaethau dŵr yn cefnogi prosesau cynhyrchu ynni a bwyd, hamdden a thwristiaeth, ac yn cysylltu cartrefi a busnesau â’r rhwydweithiau seilwaith maent yn dibynnu arnynt.

en-gb	As well as this existing natural ecosystems play an important role in providing water quality and flood management.
cy-gb	Yn ogystal, mae ecosystemau naturiol yn chwarae rhan bwysig i wella ansawdd dŵr a rheoli llifogydd.

en-gb	6.6.3  There are three main types of public drainage (often termed “mains drainage”) – foul sewers, surface water sewers and combined systems which convey both.
cy-gb	6.6.3  Mae tri phrif fath o ddraeniad cyhoeddus – carthffosydd budr, carthffosydd dŵr wyneb a systemau cyfunol sy’n cludo’r ddau.

en-gb	Whilst legislation prohibits surface water discharge to foul sewers, additionally, surface water from new developments should not be discharged to combined systems because of the risk of pollution when combined systems overflow, and because they increase the volume of contaminated water requiring transporting and treating.
cy-gb	Er bod deddfwriaeth yn gwahardd rhyddhau dŵr wyneb i garthffosydd budr, ni ddylai dŵr wyneb o ddatblygiadau newydd gael ei ryddhau i systemau cyfunol chwaith oherwydd y risg o lygredd pan fydd systemau cyfunol yn gorlifo, ac am eu bod yn cynyddu cyfaint y dŵr halogedig sydd angen ei gludo a’i drin.

en-gb	This is a costly and energy intensive process and contrary to aims for the Welsh public sector to become carbon neutral by 2030.

en-gb	In guiding new development the planning system should at the very least ensure the incorporation of measures at an individual site scale, particularly in urban areas, in order to secure cumulative benefits over a wider area.
cy-gb	Wrth lywio datblygiad newydd, dylai’r system gynllunio sicrhau bod y mesurau’n cael eu hymgorffori o leiaf  Safonau anstatudol a argymhellir ar gyfer draeniau cynliadwy ar raddfa safle unigol, yn enwedig mewn ardaloedd trefol, er mwyn sicrhau manteision cronnus dros ardal eang.

en-gb	The installation of private sewage treatment facilities within publicly sewered areas is not considered acceptable because of the greater risk of failures leading to pollution when compared to public sewers.
cy-gb	Nid yw gosod cyfleusterau trin carthion preifat mewn ardaloedd â charthffosydd cyhoeddus yn dderbyniol gan fod mwy o berygl i ddiffygion sy’n arwain at lygredd ddigwydd yn y rheini o’u cymharu â charthffosydd cyhoeddus.

en-gb	6.7.4   The planning system should maximise its contribution to achieving the well-being goals, and in particular a healthier Wales, by aiming to reduce average population exposure to air and noise pollution alongside action to tackle high pollution hotspots.
cy-gb	6.7.4   Dylai’r system gynllunio gynyddu cymaint â phosibl ei chyfraniad at wireddu’r nodau llesiant, ac yn arbennig sicrhau Cymru iachach drwy geisio lleihau cysylltiad y boblogaeth gyffredinol â llygredd aer neu sŵn ochr yn ochr â chamau gweithredu i fynd i’r afael â mannau problemus â lefelau llygredd uchel.

en-gb	In doing so, it should consider the long-term effects of current and predicted levels of air and noise pollution on individuals, society and the environment and identify and pursue any opportunities to reduce, or at least, minimise population exposure to air and noise pollution, and improve soundscapes, where it is practical and feasible to do so.
cy-gb	Trwy wneud hynny, dylai ystyried effeithiau hirdymor lefelau cyfredol a rhagamcanol o lygredd aer a sŵn ar unigolion, cymdeithas a’r amgylchedd; nodi a manteisio ar unrhyw gyfleoedd i leihau unrhyw gynnydd mewn lefelau cyfredol cysylltiad y boblogaeth â llygredd aer a sŵn, a gwella seinweddau, lle mae’n ymarferol ac yn hyfyw gwneud hynny.

cy-gb	6.7.5   Wrth roi’r amcanion eang hyn ar waith, prif egwyddor polisi cynllunio yw ystyried pa effaith y gallai datblygiadau arfaethedig ei chael ar ansawdd aer neu seinwedd a’r effeithiau y gallai ansawdd cyfredol yr aer neu’r seinwedd eu cael ar ddatblygiadau arfaethedig.

en-gb	Air Quality and soundscape influence choice of location and distribution of development and it will be important to consider the relationship of proposed development to existing development and its surrounding area and its potential to exacerbate or create poor air quality or inappropriate soundscapes.
cy-gb	Mae ansawdd aer neu seinwedd yn dylanwadu ar leoliad a gwasgariad datblygiad a bydd yn bwysig ystyried y berthynas rhwng datblygiad arfaethedig a datblygiad sy’n bod eisoes a’i gyffiniau a’i botensial i waethygu neu greu ansawdd aer gwael neu seinweddau amhriodol.

en-gb	The agent of change principle says that a business or person responsible for introducing a change is responsible for managing that change.
cy-gb	Mae egwyddor cyfrwng y newid yn dweud mai’r busnes neu’r person sy’n gyfrifol am gyflwyno newid sy’n gyfrifol am reoli’r newid hwnnw.

en-gb	In practice, for example, this means a developer would have to ensure that solutions to address air quality or noise from nearby pre-existing infrastructure, businesses or venues can be found and implemented as part of ensuring development is acceptable.
cy-gb	Yn ymarferol, er enghraifft, mae hynny’n golygu y byddai’n rhaid i’r datblygwr sicrhau y ceir hyd i atebion i fynd i’r afael ag ansawdd aer neu sŵn o seilwaith, busnesau neu neuaddau cyfagos a’u rhoi ar waith i sicrhau bod datblygiad yn dderbyniol.

cy-gb	Wrth gynnig strategaethau datblygu newydd ac wrth neilltuo safleoedd mewn cynlluniau datblygu, bydd yn bwysig osgoi gadael i ddatblygiad graddol seilwaith, tai, masnach a diwydiant greu neu waethygu anghydraddoldebau iechyd ac amwynder trwy gyflwyno derbynyddion mwy sensitif mewn ardal neu drwy wneud trigolion yn fwy agored i ansawdd aer gwael neu sŵn.

en-gb	It will be important to identify wider mitigation solutions to reduce air and noise pollution and to avoid exacerbating problems in existing air quality management areas or noise hotspots through the provision of green infrastructure identified as part of Green Infrastructure Assessments, by the provision of electric vehicle charging infrastructure or through promoting the need to consider effective design solutions.

cy-gb	Deall a Nodi Ffynonellau Llygredd Aer (Aer a Sŵn)

en-gb	6.7.11  Air and noise pollution are often, but not exclusively, emitted from the same sources, notably road transport, commercial and industrial activities.
cy-gb	Mae llygredd aer a sŵn yn aml yn cael eu hallyrru o’r un ffynonellau, ymhlith rhai eraill, sef trafnidiaeth ffordd a gweithgareddau masnachol a diwydiannol yn fwyaf nodedig.

en-gb	Consequently, areas of poor air quality often coincide or overlap with areas subject to high noise levels.
cy-gb	O ganlyniad, mae ardaloedd o ansawdd aer gwael yn cyd-ddigwydd neu’n gorgyffwrdd ag ardaloedd â lefelau uchel o sŵn.

en-gb	Even where they do not, poor air quality at one location and high levels of noise at a neighbouring location may be related to one another, depending on the characteristics of the place in question, including the way in which people use and occupy places and the way in which traffic is managed in the wider area.
cy-gb	Hyd yn oed os nad yw hynny’n wir, gall fod cysylltiad rhwng ansawdd aer gwael mewn un lleoliad a lefelau uchel o sŵn mewn lleoliad cyfagos, yn dibynnu ar nodweddion y lle dan sylw, yn cynnwys y ffordd y mae pobl yn defnyddio ac yn meddiannu lleoedd, a’r ffordd y mae traffig yn cael ei reoli yn yr ardal ehangach.

en-gb	Where air and noise pollution are generated from the same source they should be considered and addressed together and links should be made with active travel and other strategies for reducing vehicular use so as to reduce or minimise, pollution and to ensure an appropriate soundscape.
cy-gb	Lle mae llygredd aer a sŵn yn cael eu cynhyrchu gan yr un ffynhonnell dylent gael eu hystyried a’u datrys gyda’i gilydd a dylid creu cysylltiadau gyda strategaethau teithio llesol a strategaethau eraill ar gyfer lleihau’r defnydd o geir er mwyn lleihau llygredd neu ei gadw cyn ised â phosib, a sicrhau seinwedd briodol.

en-gb	6.7.12  Planning authorities must consider current and future sources of air and noise pollution as part of developing their strategies for locating new development.
cy-gb	Mae’n rhaid i awdurdodau cynllunio i ystyried ffynonellau’r presennol a’r dyfodol o lygredd aer a sŵn wrth baratoi eu strategaethau ar gyfer lleoli datblygiad newydd.

en-gb	The pattern of proposed development should be informed by the sensitivity of, and compatibility of, uses in relation to the sources of airborne pollution and the importance of ensuring appropriate soundscapes.
cy-gb	Dylai patrwm y datblygiad arfaethedig gael ei lywio gan sensitifrwydd a chydnawsedd defnyddiau mewn perthynas â ffynonellau llygredd aer a phwysigrwydd sicrhau seinweddau priodol.

en-gb	6.7.13  When developing strategies, proposing or assessing development proposals it will be essential to understand the implications of the transport demand associated with the proposal and the effect this may have now and in the foreseeable future.
cy-gb	Wrth ddatblygu strategaethau, a chynnig neu asesu cynigion datblygu bydd hi’n hanfodol deall goblygiadau’r gofynion traffig sy’n gysylltiedig â’r cynnig a’r effaith y gallent ei chael yn awr a hyd y gellir rhagweld.

en-gb	When proposing to introduce a development activity into an area the impacts which existing pollution sources (including roads, railways and industrial or commercial operations) have in terms of air and noise pollution should be carefully considered, particularly taking into account any increases in pollution levels which may be reasonably expected in the foreseeable future as a result of increased transport activity.
cy-gb	Wrth gynnig cyflwyno gweithgarwch datblygu mewn ardal, dylid ystyried yn ofalus effeithiau ffynonellau llygredd cyfredol (gan gynnwys ffyrdd, rheilffyrdd a safleoedd diwydiannol neu fasnachol) o ran llygredd aer, a sŵn gan roi sylw arbennig i unrhyw gynnydd yn lefelau llygredd y byddai’n rhesymol eu disgwyl yn y dyfodol y gellir ei ragweld o ganlyniad i gynnydd mewn gweithgarwch trafnidiaeth.

en-gb	6.7.14  Proposed development should be designed wherever possible to prevent adverse effects to amenity, health and the environment but as a minimum to limit or constrain any effects that do occur.
cy-gb	Dylai datblygiad arfaethedig gael ei ddylunio lle bynnag y bo’n bosibl i atal effeithiau andwyol ar amwynder, iechyd a’r amgylchedd ond yn y man lleiaf i gyfyngu ar unrhyw effeithiau sy’n codi.

en-gb	In circumstances where impacts are unacceptable, for example where adequate mitigation is unlikely to be sufficient to safeguard local amenity in terms of air quality and the acoustic environment it will be appropriate to refuse permission.

en-gb	6.7.15  For the purposes of this section, potentially polluting development includes commercial, industrial, energy and agricultural or transport infrastructure.
cy-gb	At ddiben yr adran hon, mae datblygiadau allai lygru yn cynnwys seilwaith masnachol, diwydiannol, ynni amaethyddol neu drafnidiaeth.

en-gb	Such development should be located in areas where there is low potential for public exposure, or where its impact can be minimised.
cy-gb	Dylid lleoli datblygiadau o’r fath mewn ardaloedd lle ceir ond ychydig o botensial i’r cyhoedd ddod i gysylltiad ag ef a lle y gellid cadw’r effeithiau yn fach.

en-gb	Novel or new development types may potentially cause pollution and should be carefully considered, and where appropriate, decisions should be based on the precautionary principle.
cy-gb	Gallai mathau newydd neu arloesol o  ddatblygiad o bosibl achosi llygredd a dylid eu hystyried yn ofalus a lle bo’n briodol, dylai penderfyniadau fod yn seiliedig ar yr egwyddor rhagofalus.

en-gb	6.7.16  Relevant considerations in making planning decisions for potentially polluting development are likely to include:
cy-gb	Mae ystyriaethau perthnasol wrth wneud penderfyniadau cynllunio ar gyfer datblygiad allai lygru yn debygol o gynnwys:

en-gb	location, including the reasons for selecting the chosen site itself;
cy-gb	lleoliad, yn cynnwys rhesymau dros ddewis y safle dan sylw;

en-gb	impact on health and amenity;
cy-gb	effaith ar iechyd ac amwynder;

en-gb	effect of pollution on the natural and built environment and the enjoyment of areas of landscape and historic and cultural value;
cy-gb	effaith llygredd ar yr amgylchedd naturiol ac adeiledig a mwynhad ardaloedd o dirwedd a gwerth hanesyddol a diwylliannol;

en-gb	impact on groundwater and surface water quality;
cy-gb	yr effaith ar ansawdd dŵr daear a dŵr wyneb;

en-gb	effect on biodiversity and ecosystem resilience, including where there may be cumulative impacts on air or water quality which may have adverse consequences for biodiversity and ecosystem resilience;
cy-gb	yr effaith ar fioamrywiaeth a chydnerthedd ecosystemau, gan gynnwys lle gallent gael effeithiau cronnus ar ansawdd aer a dŵr a allai arwain at ganlyniadau andwyol i fioamrywiaeth a chydnerthedd ecosystemau;

en-gb	the risk and impact of potential pollution from the development, insofar as this might lead to the creation of, or worsen the situation in, an air quality management area, a noise action planning priority area or an area where there are sensitive receptors;
cy-gb	risg ac effaith llygredd posibl o’r datblygiad, i’r graddau y gallai hyn arwain at greu, neu waethygu’r sefyllfa mewn ardal rheoli ansawdd aer, ardal flaenoriaeth cynllun gweithredu ar sŵn, ardal lle ceir derbynyddion sensitif;

en-gb	and
cy-gb	a’r

en-gb	impact on the road and other transport networks, and in particular on traffic generation, particularly where the proposed development is not transport infrastructure itself.
cy-gb	effaith ar y ffordd a rhwydweithiau trafnidiaeth eraill, ac yn enwedig ar greu traffig, yn enwedig os nad yw’r datblygiad ei hun yn seilwaith trafnidiaeth.

en-gb	6.7.17  The location of potentially polluting development adjacent to sensitive receptors will be unacceptable where health and amenity impacts cannot be minimised through appropriate design and mitigation measures.
cy-gb	Byddai’n annerbyniol adeiladu datblygiad allai lygru wrth dderbynyddion sensitif os nad oes modd lleihau’r effeithiau ar iechyd ac amwynder trwy fesurau dylunio a lleddfu priodol.

en-gb	It is the overall expectation that levels of pollution should be reduced as far as possible and for this reason the location of potentially polluting development should be taken into account as part of overall strategies in development plans to ensure it can be appropriately located and maximum environmental benefits can be gained through measures such as green infrastructure.
cy-gb	Y disgwyl cyffredinol yw y dylid gostwng lefelau llygredd i’r graddau pellaf posibl ac am hynny, dylid ystyried lleoliad datblygiad allai lygru fel rhan o’r strategaethau cyffredinol mewn cynlluniau datblygu ar gyfer ei leoli’n briodol a’i fod yn esgor ar y manteision amgylcheddol mwyaf posibl trwy fesurau fel seilwaith gwyrdd.

en-gb	6.7.18  Early consideration is required to ascertain whether the location and design of proposed development is acceptable where air pollution or noisegenerating development is likely to affect a protected species, or is proposed in an area likely to affect a statutorily designated site (such as Natura 2000 sites or SSSIs) or a tranquil urban green space (including but not limited to formally designated ‘quiet areas’) valued for the restorative respite and contact with nature that they offer to residents of busy towns and cities.
cy-gb	Mae angen ystyriaeth fuan i weld a yw lleoliad a dyluniad datblygiad arfaethedig yn dderbyniol lle mae datblygiad sy’n achosi llygredd aer neu sŵn yn debygol o effeithio ar rywogaeth a warchodir, neu sy’n cael ei gynnig mewn ardal sy’n debygol o effeithio ar safle dynodedig (fel Natura 2000 neu SoDdGA) neu fan gwyrdd trefol llonydd (yn cynnwys ond heb eu cyfyngu i ‘ardaloedd tawel’ sydd wedi’u dynodi’n ffurfiol) sy’n cael eu gwerthfawrogi am y saib llesol a’r cysylltiad â natur maent yn ei gynnig i drigolion trefi a dinasoedd prysur.

en-gb	Sensitive Development
cy-gb	Datblygiad Sensitif

en-gb	6.7.19  The health imperative of good air quality and appropriate soundscapes in contributing to the overall character and quality of places and the health and well-being of people and wildlife should be fully recognised.
cy-gb	Dylid rhoi cydnabyddiaeth lawn i bwysigrwydd iechyd ansawdd aer da a seinweddau priodol sy’n cyfrannu at gymeriad ac ansawdd cyffredinol lleoedd ac iechyd a llesiant pobl a bywyd gwyllt.

en-gb	It will not be appropriate to locate sensitive uses, such as hospitals, schools, care homes and housing adjacent to busy roads or other transport routes, where there are no connectivity benefits to be gained and where health and amenity impacts associated with increased exposure of people to pollution will be unacceptable.
cy-gb	Ni fydd hi’n briodol lleoli defnyddiau sensitif, fel ysbytai, ysgolion, cartrefi gofal a thai, y drws nesaf i ffyrdd prysur neu lwybrau trafnidiaeth eraill, lle nad oes manteision cysylltedd, neu lle byddai effeithiau iechyd ac amwynder sy’n gysylltiedig â chysylltiad cynyddol pobl â llygredd yn annerbyniol.

en-gb	Whilst some uses may be appropriate with the aid of good design air quality and soundscape considerations can be overriding factors, especially for sensitive uses, if they cannot be adequately mitigated and impacts minimised.
cy-gb	Tra gallai rhai defnyddiau fod yn briodol gyda chymorth dylunio da, gall ystyriaethau ansawdd aer a seinwedd fod yn ffactorau pwysicach, yn enwedig yn achos defnyddiau sensitif, os na ellir eu lliniaru’n ddigonol neu gadw’r effeithiau’n fach.

en-gb	6.7.20  Where sensitive developments need to be located close to existing transportation infrastructure for sustainable movement and access they should be designed, as far as practicable, to limit harmful substances and noise levels within and around those developments both now and in the future.
cy-gb	Pan fo angen lleoli datblygiadau sensitif gerllaw’r seilwaith trafnidiaeth presennol ar gyfer symudiadau cynaliadwy a mynediad, dylent gael eu dylunio, i’r graddau sy’n ymarferol, i gyfyngu sylweddau niweidiol a lefelau sŵn o fewn ac o amgylch y datblygiadau hyn yn y presennol ac i’r dyfodol.

en-gb	This may include employing the principles of good acoustic design and the inclusion of active travel or travel management measures as part of development proposals.
cy-gb	Gallai hynny gynnwys defnyddio egwyddorion dylunio acwstig da a chynnwys teithio llesol a mesurau rheoli teithio fel rhan o’r cynigion datblygu.

en-gb	Such development, however, should preferably be located away from existing sources of significant noise, which may include aircraft noise or roads, particularly new roads or those with programmed route improvements.
cy-gb	Yn ddelfrydol, fodd bynnag, dylai datblygiad o’r fath gael ei leoli i ffwrdd o ffynonellau cyfredol o sŵn arwyddocaol, a allai gynnwys sŵn awyrennau neu ffyrdd, yn enwedig ffyrdd newydd neu’r rheini sydd â rhaglenni o welliannau.

en-gb	6.7.21  Regard should be paid to current air quality and noise levels and the quality of the existing soundscape and account taken of any relevant local air quality action plan, noise action plan and/ or local or regional air quality strategy as part of development strategies and proposals in development plans and before determining planning applications.
cy-gb	Dylid ystyried lefelau cyfredol ansawdd aer a sŵn ac ansawdd y seinwedd sy’n bodoli ar hyn o bryd ac ystyried unrhyw gynllun gweithredu ar ansawdd aer, cynllun gweithredu ar sŵn lleol perthnasol a/neu strategaeth ansawdd aer leol neu ranbarthol fel rhan o strategaethau a chynigion datblygu mewn cynlluniau datblygu a chyn penderfynu ar geisiadau cynllunio.

en-gb	Soundscapes and Compatibility of Uses 6.7.22  Certain qualities of sound can be associated with particular places and the activities within them.
cy-gb	Seinweddau a Chydnawsedd Defnyddiau. Bydd modd cysylltu rhai priodoleddau sain â lleoedd penodol a’r gweithgareddau sy’n digwydd ynddynt.

en-gb	Taking steps to foster the continued longevity of uses and activities which provide wider cultural benefit and experience for people and contribute towards the local economy, both in terms of a vibrancy of place and in creating a space for creativity to flourish, is an important role for the planning system.
cy-gb	Mae cymryd camau i feithrin parhad parhaus defnyddiau a gweithgareddau sy’n cynnig budd a phrofiad diwylliannol ehangach i bobl ac yn cyfrannu at yr economi leol, o ran bywiogrwydd lle ac o ran creu lle i greadigrwydd ffynnu, yn rôl bwysig i’r system gynllunio.

en-gb	6.7.23  When considering the formulation of strategies or individual proposals, bearing in mind the agent of change principle, it will be necessary to identify the nature of the soundscape which exists in an area and the characteristics of the place, or specific activities, which have shaped it.
cy-gb	Wrth ystyried ffurfio strategaethau neu gynigion unigol, o gofio egwyddor y cyfrwng newid, bydd angen nodi natur y seinwedd sy’n bodoli mewn ardal a nodweddion y lle, neu’r gweithgareddau penodol, sydd wedi dylanwadu arni.

en-gb	6.7.24  The potential impacts of noise pollution arising from existing development, be this commercial, industrial, transportrelated or cultural venues (such as music venues, theatres or arts centres), must be fully considered to ensure the effects on new development can be adequately controlled to safeguard amenity and any necessary measures and controls should be incorporated as part of the proposed new development.
cy-gb	Mae’n rhaid ystyried effeithiau posibl llygredd sŵn sy’n deillio o ddatblygiad sy’n bodoli eisoes, boed yn un masnachol, diwydiannol, cysylltiedig â thrafnidiaeth neu ganolfan diwylliannol (fel neuaddau cerdd, theatrau neu ganolfannau celf), yn llawn i sicrhau bod modd rheoli effeithiau datblygiad newydd yn ddigonol i ddiogelu amwynder a dylid ymgorffori unrhyw fesurau fel rhan o’r datblygiad newydd.

en-gb	This will help to prevent the risk of restrictions or possible closure of existing premises or adverse impacts on transport infrastructure due to noise and other complaints from occupiers of new developments.
cy-gb	Bydd hyn yn helpu i leihau’r risg o osod cyfyngiadau ar safleoedd presennol neu eu cau o bosibl neu effeithiau andwyol ar seilwaith trafnidiaeth oherwydd sŵn a chwynion eraill gan feddianwyr datblygiadau newydd.

en-gb	It will be important that the most appropriate level of information is provided and assessment undertaken.
cy-gb	Mae’n bwysig darparu’r lefel fwyaf priodol o wybodaeth a chynnal y lefel fwyaf priodol o asesiad.
