Jialuhe watershed, Baijiapan region
Terrace plots are added on this hilltop with World Bank
assistance.

On the foreground are some experimental plots used to try out
different varieties of grass and shrub for their survivability.
Many of them are introduced from aboard. As far as I can tell,
none seems to survive the harsh climate here. People here probably
stick with the local variety of purple-flower alfalfa. However
Chinese are once greatly excited by some strains of seabuckthorn
introduced from Russia. Special departments have been created to
adopt it.
The region is some badly dissected by gullies that going from
one hilltop to another is a demonstration of non-Euclidean
geometry.
