This paper has argued the importance of common property to the poor especially women in pursuing their livelihoods and serving as safety nets. Almost all case studies show, however, that the existence or at least the functioning of common property regimes is threatened.
In this section, the paper discusses threats common property regimes are facing and that are identified in the case studies. Threats mentioned in the cases can be categorized as follows:
In some examples, these pressures have threatened or are threatening the viability of common property systems, contributing to greater tenure insecurity. In other instances, as will be discussed further in Section 5, common property regimes are changing or adapting to address new challenges, such that tenure security can be maintained or even improved.
The case studies identified a range of threats to common property systems. Some of these may be considered as either "internal", i.e., coming from within a community of CPR users, or "external" i.e., rooted in processes or institutions outside the control of local CPR users. In other instances, the challenges seen - such as environmental degradation or actions to privatize the commons - are a combination of both internal and external factors. Finally, pressures may not generate only challenges, but also opportunities to empower poorer households to enjoy more secure access to common property resources - as will be discussed in the final section of this paper.
