Description ABSTRACT
Studies on environmental impacts of Kol-Dam hydropower project were conducted during the year 2010-11 with the
objectives to determine the impact of construction activities on; people and their overall economy as well as on native flora and
to develop a suitable environmental management plan. The study site falls partly in Kol-Dam project area in the Bilaspur and
parts in Mandi district of Himachal Pradesh. Five sample villages were selected in the project area, three of which belongs to
Bilaspur and two to Mandi. In each village five household were selected randomly for the study purpose. Data on the
socioeconomic status regarding household information; sex ratio, literacy rate, land holding, cropping pattern, livestock status,
particular of assets, income from various on-farm and off-farm sources was recorded for individual household in each of five
villages based on before and after project scenarios. Detailed survey of native flora was done in each village adopting walk and
(Quadrate) method. Three sample plot of 0.1 hectare were laid in each village at different sites randomly for analyzing structural
and functional parameter of trees, shrubs and herbaceous vegetation. In each sample plot one sub-plot of size 10m×10m was
established to study shrub vegetation and one sub-plot of 50cm×50cm was laid to study herbaceous vegetation. The diameter of
the tree in sampled plot was determined by tree caliper. Various phyto-sociological parameters (basal area, frequency, density,
IVI, similarity and diversity index) were calculated from primary data to bring out some conclusions. In Socio-economic status, it
was revealed that like other construction activities Kol dam construction resulted in acquisition of land. Due to the loss of
cultivated land, area under different crops also suffered losses which affected the on farm income from agricultural crops. Income
from livestock was also decreased due to loss of pasture/ghasni land as well as fodder trees. Project had also been resulted in loss
of assets like houses, commercial structure and cattle sheds. A decrease in on farm income and increase in off farm income has
been observed from the affected villages, but the net income was found to be increased to some extent in all the villages. In most
of the cases maximum loss was observed in Kyan village. Hence, Kyan was the most affected among the five villages. Whereas
minimum loss was observed for Jamthal. Among the native flora, in project area Acacia catechu, Princepia utilis and
Chrysopogon montanus were the most dominant species of tree, shrubs and grasses, respectively. Ficus religiosa, Zanthoxylum
alatum and Caloris local were the least dominant species among tree, shrubs and grasses, respectively. Maximum diversity for
tree vegetation was recorded in village Ropa, whereas minimum for Harnora. Recognizing the change/impacts on different biophysical
resources status an environment management plan to mitigate the adverse impacts has been suggested.
