Find a Geography article?

I am working on a geography project, in which I have to find two articles relevant to what we've been working on, summarize them and write a bit on why they are relevant. I can't seem to find any good articles. We are learning about different types of economies (traditional, command, and market), the three industries (primary, secondary, and tertiary) the four economic resources (land, labour, capital, entreprenuarship) It needs to be fairly recent, but it can be vague on the connections to the topics, as obscure connections are my forte.
