I was just popping in to fix a redirect, when I saw that this article is using a newspaper's interpretation of what the United Nations had supposedly stated on land degradation (section 4.1). That doesn't strike me as a very reliable source - if the UN had stated something, chances are you can find the document itself, and then cite from the horses mouth directly. Just thought I'd bring some attention to the issue. -- = ? 17:29, 2 November 2012 (UTC)
For a relatively simple claim like this one, it probably doesn't much matter. One could even argue that the UN would be a primary source for this, and that the Herald, a broadsheet established in 1783, is a very reliable secondary source and thus would have been expected to do their own fact-checking on this. (That'd be a weak argument, though, as their only statement is that the UN made the claim, so not much fact-checking would have been necessary.) --Demiurge1000 (talk) 21:14, 2 November 2012 (UTC)
Inclusion of weathering and mass movement processes
I have concerns about the following sections:
Exfoliation: That's a weathering process. There is no external agent involved.
Freezing & thawing: That's a weathering process. I've removed the second paragraph as it clearly references only the weathering process. The remaining one states that freezing and thawing is related to 'gravitational movement'. However,
Gravitational erosion: Mass movement is independent of erosion. That was stated clearly in source 21.
