The claim inflates Spain's territorial share by roughly a factor of ten: the real share of the European continent is about 5% and of the EU-27 about 12–13%.
The denominator matters: 'Europe' can mean the continent (~10.18 million km² incl. Russia) or the EU-27 (~4.2 million km²). Under neither definition does Spain reach 47%.
No primary statistical source (Eurostat, INE, national statistics office) publishing a '47%' figure was found; the exact figure in the claim does not appear in any source.
The claim was made in the context of the EU Solidarity Fund; the grossly inflated size figure is used to reinforce a narrative of Spain's importance/need, but no source supports it.
