As a response to the environmentally and socially destructive practices of post-war mechanization and intensification, the concept of sustainable agriculture has become prominent in research, policy, and practice. Sustainable agriculture aims to balance the economic, environmental, and social aspects of farming, creating a resilient farming system in the long-term. Over the last few decades, various concepts have been used in research and policy to encourage the adoption of sustainable practices.

Credibility is the measure of how institutions are perceived as a result of autonomous endogenous patterns of interaction and power differences. It is not the tenure security in the sense of neo-classical economics that matters but the perceived security and whether developers have the assurance to retain the fruits of their investment. What matters in performance of institutions is not their form but their functions as it is determined temporally and spatially in terms of economic efficiency, stability and growth.

Both research and policy recognize land systems as fundamental to human life and activities. However, these two perspectives approach land from different ends and it can be difficult to see how studied variables contribute to broader policy goals. In this paper, we argue that there is a need to better select variables to study land systems as social-ecological systems, and to align research more with those policy goals.
