In agricultural systems, diversity of crops and varieties is essential to combat the risks farmers face from pests, diseases and variations in climate. Crop biodiversity also underpins the range of dietary needs and services that consumers demand. There is growing concern, however, about declining...

On-farm suppliers of crop genetic resources, farmers, in contrast toplant breeders, also use them as planting material - a reproducible production input. These farmers are different in some respects from those working in fully commercialized agriculture in industrialized economies. Many reside in...

In this chapter, a household farm model is used to predict farmer demand for four components of the agricultural biodiversity found on family farms in Hungary. Family farms in Hungary are known traditionally as ‘home gardens’. The four components analysed are: (i) richness in crops and varieties...

Farmers’ choices, given the constraints they face, determine whether or not genetic resources of value to society for future crop improvement continue to be grown on farms. Plant breeders also influence crop biodiversity on farms through the supply of new genetic materials they develop. Using a...

This chapter compares factors explaining the inter- (interspecific) and intracrop (infraspecific diversity) of cereals grown by villages in Peasant Associations (PAs) of the northern Ethiopian highlands of Amhara and Tigray, building on the household-level analysis presented for the same sites in...

This chapter builds on the household model presented in Chapter 5 [Missing markets, migration and crop biodiversity in the milpa system of Mexico: a household-farm model, by van Dusen, M. E., pp. 63-77] by exploring the role of social institutions in household access to planting material and use of ...

As the concluding chapter for this book, the scope of current research is indicated and policy implications discussed. Also considered is crop biodiversity on farms and the effect of economic change, and conservation objectives. In addition to some of the research limitations, future research...

The purpose of this bibliography is to provide researchers with a comprehensive list of the applied economics literature about in situ (on-farm) conservation of crops as of December 2004.

This chapter relates economic development and transition with farmer demand for four components of agricultural biodiversity found on family farms in Hungary using a combination of a stated preference approach andsecondary data. Family farms in Hungary are known traditionally as ‘home gardens’....

In this chapter, survey data are used to compare the determinants of intercrop (interspecific) and intracrop (intraspecific) cereal diversity on household farms in the highlands of northern Ethiopia using an approach based on a theoretic framework. Physical features of the farm, and household...
