Abstract: | Traditional modes of living or sustenance invariably relate to immediate and surrounding resources. Traditional people use many plant resources and have developed subtle and innovative uses for them in order to obtain maximum benefit. Traditional crop varieties and races that evolved over time through trial and error, not only provide basic nutritional requirements, but also food security. While the effects of the green revolution are conspicuous in the lower Himalayas, they are less visible in the study region, the Darma and Johaar valleys in the Kumaun Himalayas. Loss of crop biodiversity has taken place over the years, principally and inadvertently related to changing lifestyle and closure of traditional trade with Tibet after the 1962 Sino-Indian war. Added to this, is a growing demand for medicinal and aromatic plants (MAPs), principally Jambu (Allium stracheyii) and caraway (Carum carvi), whose acreage has increased with the concomitant decline in area under the traditional crops. In addition, the recent discovery of Yar tsa Gumba (Cordyceps sinensis) in the alpine zones of their summer homes has reduced people's interest in sowing, rearing and caring for traditional crops, viz. beans, potatoes, amaranth, whose growing season coincides with the harvesting season of Yar tsa Gumba. The present study attempts to show the causal factors behind the loss in crop biodiversity, as well as the changing lifestyle of these traditional people, vis a vis the changes in polyculture. |
