Yn ystod yr un cyfnod, mae'r sector wedi wynebu heriau mawr: cystadleuaeth fyd-eang, datblygiadau aruthrol yn y byd technoleg, Brexit a threfniadau masnachu newydd gyda'r Undeb Ewropeaidd, pandemig COVID-19, yr argyfwng hinsawdd, costau ynni sy’n cynyddu’n ddiddiwedd, y tarfu ar gadwyni cyflenwi byd-eang, prinder deunydd crai, y cynnydd mewn prisiau a phroblemau difrifol o ran llafur.

During the same period, the sector has faced major challenges: global competition, a technology explosion, Brexit and new trading arrangements with the European Union, the COVID-19 pandemic, the Climate emergency, the soaring cost of energy, disruption to global supply chains, raw material shortages, price increases and serious issues with labour availability. Some have called this the ‘perfect storm’.
