Durante los últimos años

[irmamar]

I'm not sure about the correct translation of this sentence:

He sido testigo de los cambios que ha habido en mi Comunidad durante los últimos años.

I have been (a?) witness of the changes that have been in my region during the last years / for the last years.

Thanks. :)

[Awaken]

I have witnessed the changes that have occurred in my region over the past years.

That is how I would say it in English. I'm not sure if it works as a direct translation though.

I have been a witness to the changes... would also work.

That's an idea that I want to write, so your translations work perfectly. Thanks. :)
