Description ABSTRACT
The present study “Harnessing Major Ecosystems and Changing Livelihood
Options in Cold Deserts of Himachal Pradesh” was carried out in the village Goshal of
district Lahaul and Spiti of Himachal Pradesh, to study the major linkages and the changes
the area is undergoing in its structural and functional aspects of the major ecosystems (forest
ecosystem, grassland ecosystem and agro ecosystem) and their likely influence on economy
and other natural processes, which covers land use, phytosociological studies, nutrient and
biomass estimation and their flow through the different systems. Of the total area of village
Goshal maximum area was occupied under second grade irrigated area, pea occupying
maximum per cent of the total cropped area. In forest ecosystem among trees, the species of
maximum occurrence was Juniper macropoda having maximum leaf nitrogen content. In
alpine ecosystem Agropyron longearistatum among grasses and Taraxacum officinale among
herbs showed maximum total aboveground biomass.The biomass productivity in case of crops
depicted highest aboveground biomass for potato and minimum total biomass was reported for
rajmah among crops in agro ecosystem. For water use efficiency Podophyllum peltatum was
most water use efficient species in alpine pasture ecosystem. We found that in forest and
alpine pasture ecosystem nutrient from trees and shrubs is returned back to the soil while for
grasses and herbs 30 per cent of nutrient was decomposed back and remaining some part is
returned to the agricultural fields and thus removed out of the system. In agro ecosystem, for
traditional crop (barley) the nutrients are returned back to the fields, but in case of cash crops a
considerable amount of nutrient is removed out of the system. We found that in case of cash
crops the input: output ratio is quite high and which is the basic reason for shifting of the
farming community from traditional crops to the plantation of cash crops
