A Common Property Resource or Common Pool Resource (CPR) is produced by a sufficiently large resource system that makes it costly but not impossible to exclude potential beneficiaries.
A resource system can be regarded as a stock variable that is under favorable conditions capable of producing a maximum quantity of a flow variable, without harming the stock or the resource system itself.
Examples are: Fishing grounds, vast and open pastures.
Commonpropertyresources and dynamics of rural poverty in India's dry regions
The ultimate consequence of commonresource degradation may be the permanent disruption or elimination of vital biophysical processes, of nature's regenerative activities (energy and material flows, etc.), inside the commonproperty area and in the surrounding areas as well (Jodha, 1991).
The dependence of the poor on common properly resources and the vicious circle of poverty and the degradation of such resources are important aspects of the dynamics of rural poverty.
