Can anyone recommend a good reverse-dictionary?

Hi there,

Can anyone recommend a good reverse-dictionary (where you find a word via its meaning)? As part of my resume building effort for my grad application, I'm translating documents into English. I need to find an English word that describes "abandoned land" or "land that used to be settled, but no longer is, and is being taken over again by nature." Similar to the noun form of "fallow", but not in the agricultural sense. Does such a word even exist in the English language?

If you're translating and there are words for those meanings in that language, can't you search for the direct translation?

Not sure about reverse translation dictionaries, but wouldn't "decivilized" work?

He-he, you'd think searching the direct translation would work, but I haven't been able to find one. 

"Decivilized" is close, but I was wondering if there's a noun form (describing a landscape feature, kind of like "fallow" can sometimes be a noun defining unused agricultural land, in my understanding).
