This paper addresses the issue of land security and sustainability. The paper tackles the assumption that, in the case of China, giving farmers more secure land rights would undermine the function of land as a social safety net and, as a consequence, not be sustainable or command broad support.The report draws on data from three provinces, one of which had adopted a policy to increase security of tenure in advance of the others.

Resilience is the magnitude of disturbance that can be tolerated before a socioecological system (SES) moves to a different region of state space controlled by a different set of processes. Resilience has multiple levels of meaning: as a metaphor related to sustainability, as a property of dynamic models, and as a measurable quantity that can be assessed in field studies of SES. The operational indicators of resilience have, however, received little attention in the literature.

This article reviews intellectual property rights (IPRs), with some emphasis on the protection of agricultural and life sciences innovations. The main institutional features of IPRs are first discussed, along with a brief historical background and an articulation of the main rationale for the existence of such rights. This is followed by an overview of the principal economic issues related to IPRs.

The desire for research to be policy relevant has caused many social science studies to have “engineering” dimensions. With respect to the engineering of property rights, economic approaches indicate that we require knowledge regarding the makeup of current property rights structures, how changes to current structures affect the use and management of natural resources, and how property rights have evolved.
