Scope, Limitations and Future Directions

Concepts, theoretical principles and econometric approaches are interrelated throughout the chapters of this book, but generalizations are not so straightforward. One reason why that is although the range of empirical contexts represented is broad, the crops and countries studied were selected purposively. The selection of contexts reflects the joint decisions of the national and international scientists involved, as well as the research policy environment of the country. In other words, empirical research has been conducted in countries where at least some national stakeholders have recognized on-farm conservation of crop biodiversity as a policy issue.
