It is widely perceived that the degradation of China's rangelands has accel
erated since the introduction of rural reforms in the late 1970s. The popul
ar explanation for this phenomenon has been that a 'tragedy of the commons'
exists, as privately-owned livestock are being grazed on 'common' land. Si
nce the passing of the Rangeland Law in 1985, Chinese pastoral tenure polic
y has emphasized the establishment of individual household tenure as a nece
ssary condition for improving incentives for sustainable rangeland manageme
nt, Yet household tenure has yet to be effectively established in many past
oral regions. The first objective of this article is to describe pastoral t
enure arrangements in northern Xinjiang-Uygur Autonomous Region. Its second
objective is to explain pastoral tenure arrangements, particularly the obs
erved persistence of collective action. It is argued that there is no 'trag
edy of the commons' and that it is characteristics of rangeland resources a
nd the social environment that give rise to the particular types of institu
tional arrangements found.
