Key word

Well, I found a keyword for my thesis: Existenzgruendung in der Landwirtschaft, i.e. establishment of farm-based livelhoods. I wished there was a proper word for it in English. The lack of words hampers imagination. How can I want something that I cannot express clearly? I cannot even feel it clearly. It's like searching in the dark. But once you have the word, it shines and can be found even at night in the hay.
