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.

The Impact

The study was undertaken to identify the constraints of native cattle genetic resource conservation at the farm level along with their features of breeding system and profitability. Five different study sites like south-west, northern hills, industrial zone, north-west and mid-region were selected representatively from all over the country. A total of 280 cattle farmers from the selected regions were interviewed. A multiple regression model was fitted to know the impact of contributing factors on lactation characteristics of cows. The double log linear model was also used to explore the input-output relationship of milk production. Average milk yield was 1.78 and 5.64 liter per day per cow respectively for native and crossbred cow. Contribution of age, order of lactation and stage of lactation were predictable in native cattle but not in crossbreds. Livestock farming contributed 36.4 percent of total income of the farmers studied. A crossbred cattle farming was profitable but native cattle farming was non-profitable. Indigenous cattle were preferred over crossbred due to their superior adaptability to local environmental stresses, rearing ease, low input, lesser proneness to disease and availability of native bull for mating. Per farm average number of milch cow was found to be reduced day by day and maximum number was 4 in a farm during the period 2006-07. Major causes of reduction were the non-profitability, crisis of feed, lack of investment, introduction of exotic breed etc. Responded farmers had no clear idea on conservation of native cattle.
