Sammanfattning

Perception of farmers' about the use of pesticides and genetic erosion of tetraploid wheat landraces of Ethiopia was assessed through focus group discussions with farmers, on-farm observations, personal interviews with farmers, by using structured questionnaires of temporal and spatial methods. A total of 1496 farmers from seven provinces in the country were interviewed. Farmers' knowledge about pesticide increases suggests that they are not happy on using chemicals because of their negative impact on farm land. About 75 % of the farmers believe that, although the use of pesticides may increase the production of wheat, it has a negative impact on (human) health and environment. Women showed a higher concern for pesticides' harmfulness than men. Farmers' valuation of genetic erosion was estimated as reduced importance of landraces, as shown by a the lower proportion of landraces either grown or sold on the market. The four most important factors cited for loss of landraces were reduction in land area per capita, displacement by released/modern varieties of hexaploid wheat and teff, reduced benefit from landraces, and displacement by other crops and chat. Genetic erosion of 100 % was observed for Triticum dicoccon in the provinces of Gojam and Gonder and for T. polonicum in Tigray and Gojam. Overall, genetic erosion in the country was 32.0, 35.3, 55.9, 84.4 and 84.4 % for T. durum Desf., T. turgidum L., T. aethiopicum Jakubz., T. polonicum L. and T. dicoccon Schrank, respectively.
