The use of diverse genetic resources to breed improved crop varieties has been a key driver of agricultural productivity improvements in the past century. At the same time, the adoption of modern varieties has contributed to substantial loss of traditional varieties. In this analysis, we estimate the social value provided by several proposed crop diversity conservation programs to be carried out by the Czech genebank system. We use a double-bounded dichotomous choice model to estimate the willingness-to-pay (WTP) for conserving additional crop varieties in the genebank for ten years using data collected through an online contingent valuation survey administered to a sample representative of the general Czech population (1037 respondents) and a smaller sub-sample representative of the agricultural region of South Moravia (500 respondents). Mean WTP was found to be about $9 for both the Czech and S. Moravian sub-samples, corresponding to country-wide benefits of ~$68 million. These benefits increase by 6–7% for every ten varieties conserved, implying total welfare benefits of ~$84 million for a program conserving the maximum number of 35 additional crop varieties offered in the experiment. The study illustrates an empirical approach of potential value for policymakers responsible for determining funding levels for genetic resource conservation.

Genetic Resource Conservation

AbstractThe establishment of repositories of frozen semen, for the conservation of agricultural genetic resources, is not a simple matter of collecting and freezing semen in the hope that one day it will be suitable for use in an artificial insemination procedure. Important genetic issues need to be considered; for example, how many samples should be stored and from how many individuals? Aside from these, many biological and logistic issues must be considered. Cryopreservation technology does not work equally well in all species, often because of anatomical differences in the female reproductive tract leading to significant variability in the number of spermatozoa needed in order to achieve an acceptable conception rate. Moreover, spermatozoa from different species are not equally susceptible to cryoinjury. However, it is also emerging that semen samples from individuals within a species are also of different quality; several studies have revealed that these differences reflect the quality of DNA within the spermatozoon itself and also the efficacy of biochemical functions, including metabolic and signalling systems, within individual cells. As new possibilities to select spermatozoa for insemination arise, especially the use of flowsorting for gender selection, these issues may become more significant. In this article we interpret the way in which some of this new information may impact upon the practical implementation of genetic resource conservation.
