Land allocation decisions and in situ conservation of crop genetic resources : The case of wheat landraces in Turkey

TextLanguage: English Publication details: 1997. University of California Davis, California (USA) :Description: xi, 209 pagesSubject(s): Summary: This study contributes to the ongoing discussion of the feasibility of in situ conservation of crop genetic resources by developing a linkage between a household-level analysis of farmer incentives to cultivate traditional varieties and the university outcomes observed in the household for those varieties. The availability of both household-level socioeconomic data and scientifically-measured diversity data from the same holuseholds in an area of wheat diversity in Turkey permits the empirical application of the model. Estimation of the model of diversity outcomes suggests that diversity observed in the household is shaped primarily by the household's choice of variety, rather than its management of the variety once the crop has been planted in the field. Household risk attitudes, the agroecological conditions on the household farm, and the access of the household to markers were all found to be significant factors in the household's varietial choice decision. Market-related factors, such as district-level market development and the relative prices between modern and traditional varieties, were particularly important in the household's decision to cultivate traditional varieties. Because the decision to cultivate traditional varieties appears to be the most important determining factor of household levels of diversity, and effective public-policy approach to maintaining the existing diversity level at the least cost is likely to consist of targeting the households with the highest ex ante probabilities of cultivating traditional varieties. An examination of the diversity held by a subset of household with a probability above 95 percent of cultivating traditional varieties showed these households, concetrated in three of the six surveyed districts, acounted for almost all of the named landraces in the survey. Fidings also suggest that price policies specifically targeting traditional varieties and market development focusing on the consumption characteristics associated with traditional varieties may be the most effective means of encouraging their cultivation in the future.

This study contributes to the ongoing discussion of the feasibility of in situ conservation of crop genetic resources by developing a linkage between a household-level analysis of farmer incentives to cultivate traditional varieties and the university outcomes observed in the household for those varieties. The availability of both household-level socioeconomic data and scientifically-measured diversity data from the same holuseholds in an area of wheat diversity in Turkey permits the empirical application of the model. Estimation of the model of diversity outcomes suggests that diversity observed in the household is shaped primarily by the household's choice of variety, rather than its management of the variety once the crop has been planted in the field. Household risk attitudes, the agroecological conditions on the household farm, and the access of the household to markers were all found to be significant factors in the household's varietial choice decision. Market-related factors, such as district-level market development and the relative prices between modern and traditional varieties, were particularly important in the household's decision to cultivate traditional varieties. Because the decision to cultivate traditional varieties appears to be the most important determining factor of household levels of diversity, and effective public-policy approach to maintaining the existing diversity level at the least cost is likely to consist of targeting the households with the highest ex ante probabilities of cultivating traditional varieties. An examination of the diversity held by a subset of household with a probability above 95 percent of cultivating traditional varieties showed these households, concetrated in three of the six surveyed districts, acounted for almost all of the named landraces in the survey.
